Abstract
Dezinfectanții sunt substanțe antimicrobiene care pot distruge toți agenții patogeni de pe suprafețe, materiale sau materii vii. Eficiența dezinfectării/ sterilizării depinde de modul de aplicare, durata de acțiune și concentrația utilizată. Pentru a evalua eficacitatea acestora, substanțele dezinfectante pot fi analizate din punct de vedere fizico-chimic folosind diferite metode. Cromatografia de lichide de înaltă performanță (HPLC) este una dintre tehnicile des utilizate în acest domeniu.
Scopul acestui studiu este de a pregăti și ulterior de a determina proprietățile fizico-chimice și antimicrobiene ale dezinfectanților. Au fost preparate două soluții dezinfectante cu concentrații diferite ale principiului activ, clorhexidina digluconat, și a unui agent calmant numit lidocaină.
Pentru evaluarea parametrilor de dozare și a substanțelor chimice conexe, au fost utilizate patru metode HPLC. Analizele au demonstrat că parametrii de dozare și substanțele chimice conexe se încadrează între valorile minime și maxime în momentul preparării.
De asemenea, au fost efectuate studii de stabilitate asupra soluțiilor dezinfectante, dovedindu-se că acestea sunt stabile timp de un an în condiții normale și 6 luni în condiții accelerate.
Pe toată perioada stabilității activitatea bactericidă corespunde la maxim 5 minute de contact iar activitatea fungicidă corespunde la maxim 15 minute de contact.
Concentrația propusă a soluțiilor s-a dovedit eficientă în ambele cazuri.
In the course of this research for the development of the paper, hydrogel samples based on raw whey and gelatin were obtained. Plasticization was achieved by adding glycerin, and crosslinking was achieved using copper. To confer antimicrobial properties, metallic copper was generated in situ through a reaction between copper sulfate and ascorbic acid, the latter being used as a reducing agent. The gel samples were created under conditions of excess copper sulfate, necessary for the crosslinking process, with varying concentrations of the reducer. These were poured into silicone molds and dried for 48 hours, then stored in the refrigerator. Absorption tests were conducted using the tea bag method. For this purpose, pieces of hydrogel with surfaces of approximately 5 cm² were inserted into envelopes made from non-woven synthetic material. Before the absorption process, the envelopes were moistened in distilled water, blotted with dry paper, and weighed. The degree of absorption was calculated based on the increase in mass of the hydrogels over a period of 96 hours. Measurements were initially made every 5 minutes, then every 15 minutes, and towards the end of the process, once every 24 hours. Fick's and Schott's equations were applied to analyze the kinetics of absorption. The results show that initially, water absorption followed Fick's model, but over the entire duration of the process, the absorption adhered to Schott's model. The stability of the hydrogels was investigated by repeating the absorption process four times, with the samples being air-dried for three days between cycles. Repeated tests have shown that the hydrogels are stable for at least four successive cycles of absorption.

Termenul de “cancer” a ajuns să fie din ce în ce mai cunoscut în rândul oamenilor și ajunge să stârnească frică în majoritatea cazurilor. Leucemia reprezintă forma de cancer al sângelui-fundamentul organismului. Oamenii tind să creadă că în momentul în care aceștia suferă de leucemie, pentru ei nu mai există nicio șansă de salvare, ci doar metode care să amelioreze simptomele și efectele adverse, dar oare să fie așa? Cercetări recente au demonstrat că nanoparticulele de aur și argint pot fi folosite pentru prevenirea și chiar tratarea formelor de leucemie. Dar ce sunt aceste nanoparticule, unde se găsesc și mai important , cum pot ajuta la prevenirea și tratarea acestei "tulpini" aparținătoare "bolii secolului"?
The term “cancer” has become very known among the people and it brings fear in people’s hearts in most of the cases. Leukemia is the form of blood cancer, blood being the fundament of the organism. People tend to believe that as soon as they have been diagnosticated with leukemia, they have no chance to be saved and that there are only methods that can ameliorate the symptoms and the adverse effects, but is it that way? Recent researches have shown that gold and silver nanoparticles can be used as anticancer agents and even to treat some forms of leukemia. But what are these nanoparticles, where can they be found and the most important, how can they help to prevent and treat this form of “disease of the century”?

Following the study carried out in the town of Zlatna, Alba county, regarding the sources of pollution and environmental polluting agents, during the research and determinations in the laboratory regarding the quality of water and soil, and from the field for the quality of air and noise, we learned the following conclusions :
The water quality investigation following the analyzes carried out in the 5 areas: upstream Ampoi River, Valea Mare tributary, Valea Morilor tributary, downstream Ampoi River, Fenesel tributary, from where I took samples, I can conclude the following: the pH was within normal limits at 4 of the 5 analyzed waters, falling between the values of 7.1-7.4, but the sample from the upstream of the Ampoi river had a pH of 7.7. Conductivity was according to STAS with values between 490-709 µS/cm. Turbidity was within normal limits, NO3 and NO2 were also within water quality standards, as was dissolved O2. Regarding the hardness it can be said that all the analyzed water samples are within the parameters.
The air quality investigation was carried out by measuring CO2 and SO2 using the Spark Lx Datalogger, and the values obtained are normal and within the air quality standards.
The investigation of the noise sources were determined with the PeakTech 5035 digital sound level meter in three areas within the radius of the town, the highest value is due to the car traffic on the national road that crosses the town, but the values obtained fall within the noise quality parameters in the towns .
Following the analyzes in the laboratory (water, soil) and in the field (air, noise), after processing the data it can be said that all the parameters analyzed regarding the possible sources of pollution in the city of Zlatna are within the parameters and the study area does not fall within the category of areas subject to different environmental pollution factors.

Abstract
Scopul acestui studiu a fost de a evalua influența conținutului de gelatină asupra carcateristicelor filmelor pe bază de alcool polivinilic (PVA), și anume în stabilirea morfologiei acestora prin microscopie optică, structura prin spectroscopie în infraroșu (FTIR), capacitatea de reținere a apei, porozitatea, degradabilitatea în vitro în prezența pepsinei și pancreatinei și absorbția materiei organice.
Obiectivele studiului sunt: dezvoltarea materialelor pe bază de PVA-gelatină, testarea caracteristilor acestora, stabilirea influenței conținutului de gelatină asupra caracteristicilor testate.
Partea aplicativă conține informații despre matricile de PVA-gelatină cu aplicații în domeniul medical, rezultatele obținute și discuții.
Polimerii biodegradabili au fost utilizați pe scară largă în medicină de mult timp. Polimerii biodegradabili sunt biocompatibili și pot fi utilizați cas materiale medicale, de exemplu, în suturi, materiale de fixare a fracturilor și alte aplicații. PVA este un exemplu de mterial biodegradabil care a fost utilizat în domeniul medical.
Rezultatele fizico-chimice și biochimice au demonstrat că degradabilitatea în vitro în condiții enzimatice, capacitatea de reținere a apei și capacitatea de absorbție a albuminei cresc odată cu conținutul de gelatină, în timp ce porozitatea variază invers proporțional cu cantitatea de gelatină din matricea PVA.
În concluzie, comportamentul biochimic al matricelor pe bază de PVA în timpul testelor enzimatice a demonstrat că aceste materiale pot fi ușor degradate de sucul gastric, astfel că sunt potențial candidate pentru încapsularea suplimentelor nutritive.
Scopul acestei lucrări este de a monitoriza efectul conservării thiocianatului de guanidină asupra parametrilor urinari.
Probele de urină au fost colectate și plasate în eprubete, unele conținând agent de conservare, iar altele nu, fiind stocate la temperaturi de 25°C și 4°C pentru a simula diferite condiții de depozitare. Analizele includ examinarea fizică și testarea cu benzi pentru parametri precum leucocite, nitriți, urobilinogen, proteine, pH, eritrocite, densitate, corpi cetonici, bilirubină și glucoză, alături de examinarea microscopică a urinei pentru leucocite și eritrocite. În plus, s-au efectuat analize ale creatininei și proteinelor urinare.
Rezultatele indică o menținere a nivelurilor parametrilor urinari în eprubetele cu conservant, în comparație cu cele fără conservant, sugerând eficacitatea thiocianatului de guanidină în păstrarea integrității și stabilității probelor. Parametrii urinari, cum ar fi creatinina și proteinele, au prezentat scăderi mai rapide în eprubetele fără conservant, în timp ce concentrația de glucoză a variat în funcție de condițiile de stocare, fiind influențată de prezența conservantului și de temperatură. Temperaturile de depozitare influențează rata de modificare a parametrilor, cu modificări mai rapide la temperaturi ridicate și mai lente la temperaturi scăzute.
Comparativ, probele cu thiocianat de guanidină au demonstrat o stabilitate mai mare a parametrilor urinari în ambele condiții de temperatură, în timp ce probele fără conservant au arătat variații semnificative, accentuate la 25°C. Aceste observații contribuie la o înțelegere mai bună a efectului de conservare al thiocianatului de guanidină asupra parametrilor urinari și la evaluarea eficacității sale în diverse condiții de depozitare.
Studiul a avut ca scop dezvoltarea unor filme de chitosan- alcool polivinilic modificate cu azotat de calciu, zinc și magneziu și evaluarea caracteristicilor acestora, respectiv morfologia prin microscopie optică, structura prin spectroscopie FTIR, capacitatea de reținere a apei, a glucozei și albuminei, porozitatea, biodegradabilitatea indusă în vitro de enzime, precum și capacitatea de reținere a celulelor roșii din sânge.
Obiectivele studiului sunt: dezvoltarea matricilor; caracterizarea lor din punct de vedere morfologic, structural, al determinării capacității de reținere a apei, porozității, biodegradabilității și absorbției de materie organică; evaluarea potențialului acestuia de a fi utilizate în domeniul medical.
Partea practică conține informații despre matrici de fosfat modificate cu alcool polivinilic, chitosan și diferiți ioni metalici cu aplicații în domeniul medical, precum și rezultatele și discuțiile studiului.
Diverse tipuri de polimeri derivați natural (de exemplu, alginat, chitină, chitosan, celuloză, gelatină, mătase, amidon) au fost utilizați în schele concepute pentru aplicații de inginerie a țesutului osos pentru a imita colagenul de tip I. Unul dintre cei mai larg studiați biopolimeri este chitosanul. Chitosanul singur nu este osteoinductiv și necesită combinație cu o fază anorganică bioactivă pentru a modula diferențierea celulelor stem către un fenotip osteoblast.
Rezultatele au arătat că pelicula care conține Zn 2+ are cea mai mare capacitate de reținere a apei (cu 50% mai mare decât cea a chitosan-alcool polivinilic), că prezența ionilor metalici reduce porozitatea materialului (cu ~ 19% decât cea a chitosanului- alcool polivinilic) și nu influențează semnificativ gradul de degradare enzimatică. Filmul care conține toți cei trei ioni metalici a prezentat cea mai mare capacitate de absorbție a glucozei (46% decât cea a chitosan-polialcoolului vinilic), dar a dat rezultate mai puțin satisfăcătoare în ceea ce privește capacitatea de absorbție a albuminei în comparație cu filmul de chitosan-polivinil alcool nemodificat.
Concluzia este că pelicula de chitosan-polivinil alcool modificat cu Zn 2+ este cea mai bună în ceea ce privește retenția de apă, globulele roșii și adsorbția glucozei, astfel că poate fi un posibil candidat pentru aplicații medicale.
Scopul acestui studiu a fost să obțină și să caracterizeze pelicule realizate din alcool polivinilic și amidon, explorând influența conținutului de amidon asupra proprietăților fizico-chimice și morfostructurale ale acestor pelicule. Obiectivele au inclus obținerea peliculelor, caracterizarea morfologiei acestora prin microscopie optică, analiza structurii prin spectroscopie în infraroșu și evaluarea proprietăților cum ar fi capacitatea de reținere a apei, porozitatea, biodegradabilitatea în mediul enzimatic, absorbția de glucoză, absorbția de albumină și fixarea hematiilor.
Partea aplicativă a studiului a fost dedicată procesului de pregătire și caracterizare a peliculelor, folosind amidon și alcool polivinilic modificat ca materiale de bază. Această secțiune abordează în detaliu etapele de preparare a peliculelor și a investigat caracteristicile lor fizico-chimice și morfostructurale. Astfel am examinat metodele de obținere a peliculelor, inclusiv procesele de amestecare și formare a acestora.
Testele realizate au evidențiat că peliculele pe bază de amidon și alcool polivinilic modificat au o morfologie și structură adecvată, pot reține apă și prezintă o porozitate controlată. De asemenea, au demonstrat o biodegradabilitate promițătoare în medii enzimatice și capacitatea de a absorbi glucoză și albumină, precum și de a fixa hematiile. Aceste caracteristici sugerează un potențial considerabil pentru utilizarea lor în ambalarea alimentelor, în medicină și în industria farmaceutică.
Paracetamolul, cunoscut și sub numele de acetaminofen, este un medicament utilizat frecvent pentru ameliorarea durerii și reducerea febrei. Este unul dintre cele mai comune analgezice și antipiretice, fiind adesea preferat datorită eficacității sale și a profilului de siguranță favorabil atunci când este utilizat corect. Acesta face parte din grupa terapeutică a anilidelor și este disponibil în diverse forme farmaceutice, inclusiv: comprimate, capsule, soluții orale, supozitoare și forme injectabile.
Pentru a facilita administrarea acestor principii active, ele au fost formulate sub formă de soluții orale, această prezentare asigură o absorbție rapidă și este mai ușor de utilizat, în special pentru copii și persoanele care au dificultăți în a înghiți comprimate. Unele principii active se dizolvă ca atare și altele cum este paracetamolul se dizolvă la temperaturi mai ridicate.
Ordinea de adăugare a substanțelor active și a excipienților este foarte important pentru a reduce reacțiile adverse cum ar fi precipitarea sau tulburarea unei soluții.
Scopul acestei lucrări este de preparare a unei soluții ce are în compoziția sa paracetamol ca substață activă și testarea proprietăților fizico-chimice prin noile metode HPLC.
Pentru a realiza acest lucru se prepare o soluție de paracetamol și excipienți (conservanți: metil paraben și propil paraben). Pentru determinarea dozării paracetamolului și impuritățiilor s-au folosit metode HPLC. După efectuarea testărilor s-a demonstrat că soluția preparată este în parametrii propuși. În soluția propusă substanța activă paracetamol se dizolvă la aproximativ 80 °C.

Colon cancer remains a leading cause of cancer-related mortality globally, necessitating novel therapeutic strategies. Phytochemicals such as resveratrol and genistein have garnered attention due to their potential anticancer properties, which include modulating cell growth and inducing apoptosis in various cancer models. This study aims to explore the effects of resveratrol and genistein on colon cancer cell lines, specifically focusing on the induced mutational changes and their implications for cancer therapy, using advanced next-generation sequencing (NGS) techniques.
We selected two colon cancer cell lines (HCT116 and RKO) that differ in their genetic backgrounds and mutational profiles. These cell lines were treated with resveratrol and genistein at various concentrations, individually and in combination, at 24,48 and over a 72-hour. We choose the best IC50 obtained at 24h for both cell lines and both natural compounds.
Following treatment, comprehensive genomic profiling was conducted using NGS to assess changes in the mutational status of these cell lines. We used the 50 cancer genes panel from Thermo Scientific and the experiments run into the Ion Torrent platform after nucleic acids extraction and quantification and library preparation. Our results showed that each cell line responded uniquely to the treatments, strongly influenced by their initial genetic characteristics. For instance, HCT116 cells, known for their high microsatellite instability (MSI-H), exhibited more significant apoptotic rates and extensive mutational changes, especially when exposed to both phytochemicals simultaneously. This suggests a synergistic interaction that may be pivotal in optimizing therapeutic outcomes.
The study highlights the critical role of genetic context in determining the responsiveness of colon cancer cells to treatment with natural compounds. Our findings support the potential of resveratrol and genistein as part of a targeted therapy approach, which could be tailored based on the genetic makeup of individual tumors. This personalised approach could enhance the efficacy of treatment modalities and lead to better management of colon cancer, emphasising the need for further clinical studies to validate these findings. The integration of phytochemicals with conventional therapies could potentially shift the paradigm of cancer treatment towards more specific, less toxic, and genetically informed strategies.

Fluoride transitional metal ion complexes have several applications in catalysis, material science, due to their unique properties and reactivity. In this work we present the synthesis and structural analysis of two fluoro-manganese (III) complexes obtained with hydrogen difluoride ion, a special fluorinating agent. The compounds show a combination of strong hydrogen bonds (as provided by hydrogen difluoride ion) and coordinative covalent bonds. Understanding the coordination chemistry of fluoride transition metal complexes helps in elucidating fundamental principles of coordination chemistry and metal-ligand interactions, contributing to the development of new coordination compounds with tailored properties.
The sound numerical solution of a research, high tech engineering, or economics problem involves a four step process: (i) formulation of the underlying mathematical model; (ii) design of an algorithm for solving the mathematical model in a finite number of steps; (iii) a computer code algorithm implementation, enabling floating point computations; (iv) (for expert implementation) optimization of the information flow on the different available hardware architectures (e.g., cache-based
memory hierarchy, distributed memory access, GPU accelerators).
The present lecture illustrates this four step process for the numerical solution of the Riemann integrals by automatic adaptive quadrature (AAQ), which was promoted by the rich, half century, accumulated empirical evidence as the most performant numerical method devoted to this aim.
In this paper, we present some results about
the aproximation of fixed points of enriched strictly
pseudocontractive and enriched nonexpansive op-
erators. There are numerous works in this regard
(for example [9], [10], [11] [14], [16], [35] and ref-
erences to them). Of course, the bibliografical ref-
erences are extensive and they are mentioned at
the end of this paper. In order to approximate
the fixed points of enriched strictly pseudocontrac-
tive and enriched nonexpansive mappings, we use
the Krasnoselskii iterative algorithm for which we
prove weak and strong convergence theorems.
Also, in this paper, we make a comparative study
about some classical convergence theorems from
the literature in the class of enriched strictly pseu-
docontractive and enriched nonexpansive mappings.
In this article, we establish a fixed-point theorem in the setting
of complete rectangular b-metric spaces endowed with a
partial order. We note that several consequences can be
obtained from the main result.
Abstract: - In this paper it is demonstrated that a wind turbine, WT, which is operating at maximum power point, MPP, at significantly varying wind speeds large variations in the power injected into the grid occur. These power variations can be compensated if the wind system has storage facilities for captured wind energy. This experimental data from a 2.5 [MW] WT in operation in the Dobrogea area are processed.
Abstract: The paper presents some characterizations for two concepts of nonuniform dichotomy with growth rates of discrete-time systems in Banach spaces.
The aim of this paper is to give integral characterizations for uniform dichotomy with differentiable growth rates of skew-evolution cocycles in Banach spaces.
Pythagoras said "The world is run by numbers.". How right he was! In the present work, I intend to present you a branch of mathematics that is a little more abstract: astronomy. I will try to capture some classical problems of astronomy in which some relatively simple notions are used. We will walk through "time", discovering sidereal times, apparent solar times and average solar times. We don't discuss astronomical events every day, but it's such a fascinating and so "mathematical" field that it wouldn't take us light years to finish the subject.
In this paper work I will introduce the dynamical covariant derivative operator on the dual space of a given Finsler space using the idea of Legendre duality between the lagrangian formalism and the hamiltonian formalism. Making use of this new operator introduced I will proof that the solution curve equations and their deviations have an elegant geometrical expression.

The main purpose of this paper is to extend some fixed point results for single valued $b$-enriched nonexpansive mappings to the case of multivalued mappings.
This research paper aims to investigate how the eigenvalues of Sturm-Liouville problems behave when the differential equation or coefficients are subjected to perturbations. Specifically, the study seeks to examine the continuity of eigenvalues concerning these perturbations.
The research involves theoretical analysis, numerical simulations using Python and MATLAB programming languages, and potential development of new mathematical techniques to characterize the behavior of eigenvalues.
The main aim of this paper is to give characterizations of Datko type for uniform dichotomy in mean with growth rates concept for reversible stochastic skew-evolution semiflows in Banach spaces. As particular case, we obtain integral characterizations for uniform exponential dichotomy in mean and uniform polynomial dichotomy in mean.
The obtained results are generalizations of well-known theorems about uniform h-dichotomy of variational systems in deterministic case.
Abstract
The starting point of this paper is the central results of the article by Al-Dolat and Jaradat, “A refinement of the Cauchy-Schwarz inequality accompanied by new numerical radius upper bounds”. The purpose of this paper was to generalize the results obtained by them and to obtain an improvement of those inequalities. This aspect is concretely presented based on an example. An improvement of the inequality of means was used in the proofs, which led to some better results for inequalities on certain powers of numerical radius of some operators.
Keywords: linear operator, bounded operator, numerical radius, inner product, norm, inequality
I have chosen to develop a web application that allows users to take three health tests - a vision test, a color blindness test, and a hearing test - from the comfort of their own homes in order to simplify access to crucial information about their health.
The purpose of this project is to provide a convenient and accessible way for people to assess these essential aspects of their health in a non-invasive manner. With the help of this application, users can check their visual acuity, color discrimination ability, and hearing acuity, thereby contributing to awareness and monitoring of their health in an efficient and convenient way. In this way, we hope to improve the quality of life and the overall health of our users by offering them a useful tool for self-assessment and identifying potential health issues.
The project involves the development of an interactive and user-friendly web application that offers users three types of health tests, each addressing a specific aspect of human health.
The vision test evaluates users' visual acuity by displaying numbers on the screen, which they must resolve in a dynamic and intuitive interface. This provides them with insight into the quality of their vision.
The color blindness test identifies possible color discrimination deficiencies by displaying images specially designed for this purpose. Each image contains a number from one to nine, and the user must select the number they see in the interface.
The hearing test assesses auditory acuity. Users need to listen to sounds of different frequencies with headphones and then mark "yes" if they heard the sound or "no" if they did not.
The test results are saved in a database and presented in an easily understandable format through a table and a graph.
This application represents an innovative solution for self-assessment and health awareness and is aimed at individuals interested in their health status and those who want to continuously monitor their basic health parameters.
Therefore, the project focuses on promoting health and well-being through a modern and user-friendly application, offering users the opportunity to check and monitor their health in a convenient and informative way.

Background: As healthcare increasingly integrates digital technologies, it is crucial to ensure that medical professionals possess robust digital competencies to maximize the benefits of these technologies. Mastering fundamental digital skills is essential before engaging with more complex digital health technologies.
Aim: This study aims to assess the general digital competencies of doctors in Chișinău, Moldova, and to identify specific areas needing improvement, thereby providing a foundation for tailored educational programs.
Materials and Methods: In April 2024, data were collected using the My DigiSkills tool, a self-assessment online questionnaire developed under the European Commission's DigCompSAT project by ALL DIGITAL. This cross-sectional study involved 91 doctors from various medical institutions in Chișinău, who self-assessed their digital competence levels across five areas: Information and Data Literacy, Communication and Collaboration, Digital Content Creation, Safety, and Problem Solving.
Results: Results indicate that while doctors in Chișinău generally possess a medium level of digital competencies, significant gaps are evident in some of the 21 individual digital competences. Notable demographic differences in age and gender suggest varying levels of digital literacy.
Conclusions: The findings underscore the need for targeted digital skills training. Training programs should be designed to meet the diverse needs identified through self-assessment, ensuring equitable access to professional development opportunities that enhance digital proficiency and improve overall healthcare quality.

Mobile technology and artificial intelligence are opening new avenues for improving public health, particularly in the field of dermatology. This work presents the concept of a mobile application designed to assist in detecting potentially cancerous moles, with the aim of promoting early detection of skin cancer and reducing the burden on healthcare systems.
Skin cancer is a growing public health issue worldwide, and in Romania, despite a relatively low incidence of melanoma, there are some of the highest mortality rates associated with this disease. This paradox highlights the need for effective methods for early diagnosis and rapid intervention.
The proposed research investigation uses a Convolutional Neural Network (CNN) to classify images of moles based on their risk for skin cancer. Users can capture a photograph of the suspect mole, which the application then processes using a specialized CNN model. The model is trained with labeled datasets by expert dermatologists, using the HAM10000 dataset, which contains over 10,000 dermoscopic images of pigmented lesions.
The application provides a preliminary classification into seven categories, indicating whether the mole is benign or malignant, with a target accuracy of at least 93%, aligning with other similar studies. This initiative can promote awareness and early detection of skin cancer, offering a preliminary screening tool that is easy for the use of general public.

Laboratory test results can be challenging to interpret, which is a big problem for the great majority of the population. In the usual laboratory tests, the patient can find abbreviations of tests performed and a lot of medical terms that are hard to understand. The proposed system's objective is to help patients understand laboratory test results and keep track of their health. To achieve this, we developed an application that can scan a laboratory test result using a pre-trained Convolutional Neural Network-based Optical Character Recognition tool (OCR) in order to extract the data. The application translates the abbreviations of each test performed and stores the processed data locally. The application also provides explanations for each test's normal range, making it easier for patients to understand their results. Additionally, the application's data visualization feature enables patients to track their progress over time and make informed decisions regarding their health. With the ability to share results with healthcare providers, patients can receive professional medical advice and treatment based on their test results. The application's adaptability is a key strength. It can effectively handle different types of laboratory tests from various medical institutions, regardless of the analysis methods used. This ensures a comprehensive and reliable health-tracking experience for the user.

Parkinson’s disease (PD) is a chronic, progressive neurodegenerative disease characterized by both motor and non-motor features. The primary objective for us is the early diagnosis of patients using Artificial Intelligence (AI). To accomplish that we developed an Artificial Intelligence Model (model) that diagnoses PD using data collected from the patient’s gait. The data is represented by multiple images that are generated from raw data collected using a physiograph created by our team. For the research scope, we designed a Generative Adversarial Network that is capable of learning and reproducing real biomechanical data representing Parkinsonian patterns of gait, which is able to generate augmented data that will be used further for training our classification models.

A dataset is a collection of information, usually structured in a format that can be used in research or training various applications such as machine learning. Datasets are fundamental to many analytical processes because they provide raw data that can be used in different applications. While some datasets are readily available, others must be specially curated. Creating a dataset often involves automated data collection methods, with web scraping being a popular technique. Web scraping employs scripts to extract data from online sources, demanding robust programming skills and considerable maintenance effort. It is important to note that the method can break site policies because it may violate terms of service agreements. A proposed solution for gathering the required information is to create a Robot Process Automation (RPA) flow, which collects information from various sources as a normal user would do manually. A use case of RPA flow involves using it to compile a medical dataset that contains information about clinical trials for various drugs. The dataset will be utilized in researching the effects of placebo drugs on people. The information is available on the clinicaltrails.gov site and the results of different trials can be downloaded manually as files. Automating this process can be done by creating a flow in UiPath by linking predefined activity blocks, which simplifies the creation and maintenance of the workflow. Running the flow will follow the steps that a normal user would do for downloading the results of different trials from the site. This approach eases data collection, allowing medical staff to generate datasets, without the need for deep technical skills, that can be used in different investigations. In conclusion, an RPA flow is a straightforward way to gather information for a dataset, circumventing the complexities of traditional programming-based approaches like web scraping.

Diabetic retinopathy (DR) is a diabetic complication that affects the retina of the eye. Due to the accumulation of sugar in the blood, the blood vessels in the retina can bleed. This condition requires proper monitoring and treatment to prevent vision loss. Using the Spatial Transformer Network (STN) method connected to a convolutional neural network (CNN), retinal images are correctly aligned to accurately identify and diagnose lesions associated with this condition. The STN can learn to refocus the images to find the relevant areas that indicate the occurrence of microaneurysms, hemorrhages or exudates. This refocusing is achieved through spatial transformations, and the STN contributes to improved accuracy and efficiency in finding lesions. We used a public dataset which contains samples of fundus images of both the healthy eye and the eye with DR. In this study, we verify which neural architecture is the most performing and efficient, using performance evaluation metrics and execution times. The proposed technique, Trans-NeuroVision Area (TNVA), helps in the prompt detection and categorization of retinas into healthy and problem ones.

UN MATERIAL UTIL IN ACTIVITATEA DIDACTICA
The persistent digital divide in higher education is prominently shaped by socioeconomic status, significantly impacting access to Information and Communication Technologies (ICT). This study examines the multi-layered nature of digital inequalities—ranging from basic access and digital literacy to differential benefits derived from technology usage—highlighting how these disparities are intricately linked with social stratification. Insights from various studies underline the critical need for educational institutions to adopt strategies that not only enhance digital access and literacy but also ensure equitable digital empowerment across diverse student demographics, thereby minimizing social and digital disparities. The integration of ICT in social work services is becoming indispensable rather than optional, driven by the necessity for strategic and flexible applications of emerging technologies. These advancements offer significant opportunities for innovation in service delivery, enhancing accessibility to essential resources for effective social work practice. This study explores how the evolution of technology affects not only the training of social workers but also their practice, particularly in light of the varying digital competencies among students which subsequently affect their educational outcomes and integration into the labor market. Given the dynamic and often unequal nature of the online environment, this digital disparity poses substantial challenges in ensuring equitable access to opportunities within the knowledge society.
The materials commonly used to package fresh meat are of petroleum origin and contribute significantly to environmental pollution. On the other hand, obtaining biodegradable materials faces many challenges, mainly inferior mechanical properties, but also reduced stability in the presence of meat, as shown in this research study. In the direct interaction between the whey and gelatin-based hydrogel and meat, inside the packaging and at refrigeration temperatures, substance exchange processes prevailed, although the original purpose of the hydrogels, to absorb excess moisture from the meat and to ensure optimal preservation conditions of fresh meat qualities, was achieved. These results encourage at least two directions of development of the formulation used in the study: towards the improvement of the dye-free formulation and, towards the development of an innovative meat marinating solution formulation with a dual role – as a biocompatible absorbent and as a tenderizing and flavoring agent.
Scopul activității experimentale a fost bazat pe studiul influenței adaosului de pesmet asupra caracteristicilor fizico-chimice și senzoriale ale pâinii albe, realizându-se analize la 1 zi și 3 zile pe 4 tipuri de pâine cu conținuturi diferite de pesmet.
În urma analizelor de laborator efectuate pe pâini, s-a constat că adaosul de pesmet îmbunătățește volumul și timpul de dospire, scade duritatea cojii, crește umiditatea pâinii și a prezentat caracteristici mai atenuate ale procesului de învechire și valori mai ridicate ale conținutului de polifenoli și a activității antioxidante.
Utilizând pesmetul se obține o pâine cu caracteristici fizico-chimice apropiate sau chiar mai ridicate cu cele ale pâinii albe fără pesmet și totodată, valorificând pâinea uscată, putem reduce risipa alimentară.

În prezentarea propusă, intitulată “CERCETĂRI PRIVIND COMPOZIȚIA FIZICO-CHIMICĂ A DISTILATELOR DE CAISE OBȚINUTE ÎN REGIUNEA SATU MARE (SĂUCA)” sunt prezentate analizele efectuate pe 4 tipuri de pălincă de caise din același an, dar de la producători diferiți, incluzând și o mică parte teoretică despre modul de producere a distilatelor de caise.
Activitatea experimentală a avut ca scop studiul influenței adaosului de gumă xantan asupra caracteristicilor pâinii pe bază de faină de orez.
Au fost pregătite 4 tipuri de pâini, pâinea de control fără gumă xantan și pâinile cu conținuturi variabile de gumă xantan. Pâinile obținute au fost lăsate să se răcească la temperatura camerei și trimise la analiză. Analizele s-au făcut la o zi și la 3 zile de depozitare.
Folosirea gumei xantan la obținerea pâinii pe bază de făină de orez poate avea câteva beneficii în ceea ce privește îmbunătățirea unor caracteristici tehnologice și senzoriale ale pâinilor, dar nu conduce la creșterea valorilor nutritive ale acesteia.

În acest studiu s-a urmărit îmbunătățirea stabilității oxidative a uleiului de floarea soarelui prin adaosul de plante aromatice cu acțiune antioxidantă. În uleiul de floarea-soarelui au fost adăugate frunze uscate și măcinate de pătrunjel și mărar în proporție de 0,5 și 1%, probele au fost lăsate timp de 3 zile la macerat, apoi s-au filtrat și s-a testat eficacitatea antioxidantă a celor două plante. Următorii parametrii au fost analizați: aciditate, substanțe insolubile în eter, indice de peroxid, indice de iod, indice de p-anisidină, conținut de polifenoli.
Prunus spinosa L., commonly known as blackthorn, is rich in bioactive compounds such as flavonoids, anthocy-anins, phenolic acids, vitamins, minerals, and organic acids, displaying strong antioxidant and antibacterial properties. This investigation aims to assess bioactive compounds in fresh and lyophilized blackthorn fruits and analyze ethanolic extracts for phenolic content, antioxidant activity, and antimicrobial effects. The primary objective was to develop a chitosan-based film with antimicrobial and antioxidant properties, targeting the enhancement of food packaging solutions, along with inhibition of S. aureus bacteria. Results showed that ethanolic extracts of blackthorn possess significant antimicrobial efficacy, demonstrating notable effectiveness against S. aureus. Notably, the film incorporating an 80% ethanolic extract demonstrated greater effectiveness against S. aureus-inoculated cheese. This outcome underscores the inhibitory potential of blackthorn extracts on S. aureus growth within a food matrix.

The main objective of this investigative endeavor is to thoroughly identify and analyze potential additives or contaminants within milk products originating from a widely recognized brands. Through meticulous scrutiny and rigorous testing methodologies, the goal is to ensure the milk products uphold stringent quality standards and comply with regulatory mandates. By pinpointing any adulterants, whether deliberate or inadvertent, this inquiry aims to uphold consumer well-being and confidence by advocating for transparency, accountability, and adherence to industry standards.
Objective/World link
Food adulteration is a global concern and developing countries are at higher risk associated with it due to lack of monitoring and policies. However, this is one of the most common phenomena that has been overlooked in many countries. Unfortunately, in contrast to common belief, milk adulterants can pose serious health hazards leading to fatal diseases. Qualitative detection of adulterants in milk are simple color based chemical reactions.
Research Question
How can we effectively identify and quantify adulterants in milk products from reputable brands, and what are the implications for consumer safety and regulatory compliance in the dairy industry?
Background: With the rapid proliferation of Artificial Intelligence (AI) in daily
life, understanding the psychological and demographic determinants of technology acceptance is crucial. Objectives: This research aimed to investigate the mediating role of technology-related anxiety in the relationship between video gaming frequency and the consumption of films featuring humanoid robots, and to
explore how age moderates this mediated relationship. Methods: The study employed a cross-sectional design with quantitative analysis to test the proposed
moderated mediation in a sample of 327 participants. Results: Findings reveal
that a higher frequency of video gaming predicts an increased likelihood of
watching films with humanoid robots, mediated by reduced technology-related
anxiety. This mediation effect was notably pronounced among participants aged
22. Despite the significant mediation effect at age 22, the moderated mediation
index suggested that the strength of this mediation does not significantly vary
across different age groups. Conclusions: These insights contribute to a nuanced
understanding of technology acceptance, emphasizing the role of emotional and
demographic factors in shaping our interactions with AI
In this paper I propose to argue the following: 1. In the history of philosophy there are several landmarks relevant to the approach and understanding of mental illness. In particular, philosophical orientations dealing with the meaning and role of human consciousness are important in this respect. I have in mind both the specific approaches of phenomenology and philosophy of mind, both of which provide significant analyses of phenomena specific to psychiatry. 2. At the intersection of philosophy and psychopathology, already explored with Jaspers, but having undergone an impressive development in recent decades, mental illnesses are described as disorders of consciousness, of the self, of language or as alterations occurring at the level of intersubjectivity.
Of these, I will consider alterations of consciousness and self. Becoming aware of oneself represents a leap for the self, which is characterised by the fact that it begins to distinguish itself from other people and the world, conceives of itself as autonomous, a leap that is closely linked to the development of a type of logical, clear, stringent, universally valid thinking, capable of discovering determined, enduring, recognisable objects in the world, revealing uniformities. Alterations in the experience of the self are part of the psychiatric sphere. Schizophrenia is considered a disease of consciousness, which interferes with and interrupts the human being's search for the meaning of life and the maintenance of emotional security. The illness manifests itself in the degradation of self-experience and loss of identity, which gradually becomes a pathological issue. The roots of psychiatry are to be found in classical philosophical writings, with Plato equating virtue with mental health.
În zorii secolului XXI, Uniunea Europeană a căutat să-și redefinească și să-și consolideze structura, aspirând la o integrare mai profundă și mai eficientă a statelor membre. Acest vis a prins contur prin Tratatul de la Lisabona, un document esențial care a remodelat peisajul politic european și a fortificat temelia pe care se construiește Europa de astăzi.
Tratatul de la Lisabona, semnat în orașul cu același nume, a fost o inovație pentru instituțiile europene, aducând cu sine un aer nou de democrație și eficiență. Prin acest tratat, UE nu doar că și-a reafirmat valorile și obiectivele, dar a și creat mecanisme prin care vocea fiecărui cetățean să poată fi auzită mai clar și mai puternic în corul decizional european.
Rolul Tratatului de la Lisabona în consolidarea construcției europene este unul plurivalent, contribuind la o Uniune mai coezivă, mai transparentă și mai adaptată provocărilor secolului nostru.
Noul Tratat de la Lisabona, cunoscut și sub numele de „Tratatul de Reformă”, oferă doar o amendare a tratatelor considerate a fi fundamentale (Tratatul privind Uniunea Europeană și Tratatul privind funcționarea Uniunii Europene), așa cum au făcut, la vremea lor și Tratatele de la Amsterdam și Nisa.
Trebuie spus că Tratatul de la Lisabona a dat naștere unei serii de dezbaterii în lumea științifică. Astfel în lucrarea „From Dual to Cooperative Federalism. The Changing Structure of European Law”, Robert Schütze face mai multe considerații cu privire la evoluțiile înregistrate în structura dreptului european. El afirmă că epoca pe care o traversează dreptul european se caracterizează printr-o structură în schimbare „de la federalismul dual la cel de cooperare”. Este de remarcat că – în argumentarea tezelor privind federalismul – Robert Schütze a stăruit asupra locului și rolului afacerilor externe într-o Federație.
Alți autori precum Finn Laurese consideră că Tratatul va aduce eficiență instituțiilor, o mai mare legitimitate Parlamentului European precum și coerență acțiunii externe. În același sens al aspectelor instituționale și de politici europene se exprimă și Christian Kaunert. Acesta consideră că Tratatul de la Lisabona conferă Comisiei Europene statutul de autoritate supranațională în ceea ce privește spațiul european al libertății, justiției și securității. Prin intermediul acestui tratat Uniunea Europeană beneficiază de unul dintre cele mai importante rezultate ale procesului de integrare.
Astfel, Tratatul de la Lisabona nu este doar un document juridic, ci un reper semnificativ în evoluția comunității europene, reflectând voința statelor membre de a-și uni forțele într-un proiect comun, de a-și consolida valorile și de a-și întări capacitatea de a face față provocărilor și oportunităților unei lumi în continuă schimbare.
The present communication aims to analyze how children's fantasy literature is utilized didactically in fourth-grade textbooks. We will be focusing, on one hand, on examining the selection of fantasy texts by textbook authors, and on the other hand, we will pay attention to the types of methods and didactic techniques associated with a good understanding and practice of fantasy literary texts, relating to the needs and curiosities of contemporary students. Moreover, the selection of texts will also reveal something about the concern of textbook authors to connect students with the challenges of contemporary literature, as well as the level of openness towards tasks involving dual referencing to content - theoretical and pragmatic (the interactive/playful dimension of workloads, the appeal to Multiple Intelligences Theory).
Abstract

Uniunea Europeană este o organizație internațională supranațională compusă din 27 de state membre. Înființarea și funcționarea Uniunii se întemeiază pe transferul de suveranitate operat de state, ce conferă organizației competențele necesare pentru realizarea obiectivelor stabilite prin tratat și, implicit, personalitate juridică proprie.
Atribuirea personalității juridice este atestată prin tratatele care au stat la baza constituirii Uniunii Europene. Până la intrarea în vigoare a Tratatului de la Lisabona, la 1 decembrie 2009, Uniunea nu a dispus de personalitate juridică, interesele sale fiind reprezentate de instituțiile Comunităților Europene. Ca urmare a evoluției tratatelor, personalitatea juridică a organizației a fost recunoscută expres în art. 47 TUE: ,,Uniunea are personalitate juridică.’’
Personalitatea juridică a Uniunii este confirmată și de competența acesteia de a edicta reguli și de a lua măsuri pentru impunerea respectării lor. Potrivit art. 228 din TFUE, instituțiile UE adoptă regulamente, directive, decizii, recomandări și avize, pentru exercitarea competențelor Uniunii. Problematizare privind actele normative, forța lor juridică, adoptare, recepția normativă sau aplicarea directă, după caz, în legislația națională a statelor.
Personalitatea juridică a Uniunii poate fi analizată sub două aspecte i.e. personalitatea juridică internă și personalitatea juridică externă. Prin intermediul personalității juridice interne, Uniunea are cea mai largă capacitate juridică recunoscută în fiecare stat membru. Cu titlu exemplificativ, prin prisma acestei forme a personalității, Uniunea poate sta în justiție împotriva unui stat membru căruia îi poate fi imputată încălcarea obligațiilor rezultate din tratate, fiind reprezentată de Comisie, potrivit art. 258 TFUE. Problematizare, exemple practice
Datorită personalității juridice internaționale, UE poate încheia acorduri cu una sau mai multe țări terțe sau organizații internaționale, dacă se prevede astfel în tratate ori dacă este necesar pentru realizarea obiectivelor. e.g. Acordul dintre UE și NATO privind securitatea informațiilor, intrat în vigoare în 14 martie 2003.
În virtutea personalității juridice internaționale, Uniunea Europeană, potrivit art. 6 alin. (2) din TUE, a devenit parte la CEDO. În consecință, Curtea de la Strasbourg va avea jurisdicție asupra protecției drepturilor omului la nivelul UE, fiind o modalitate diplomatică de a stabili o relație între cele două organizații internaționale. Problematizare
Uniunea Europeană, în temeiul personalității juridice, își poate reprezenta interesele în fața instanțelor, având calitate procesuală activă sau pasivă, după caz. e.g. Cauza C 552/09 Comisia Europeană v. România, reclamanta a invocat neîndeplinirea de către România a obligației ce îi revenea potrivit Directivei nr. 79/409/CEE privind conservarea păsărilor sălbatice. Problematizare
Recunoașterea personalității juridice a UE influențează în mod substanțial statele membre, dar și situația cetățenilor acestora. Oamenii nu mai sunt doar cetățenii unui stat, ci sunt cetățeni ai Uniunii, dobândind drepturile și obligațiile ce derivă din acest statut. În conformitate cu art. 9 din TUE și art. 20 din TFUE este cetățean al Uniunii orice persoană care are cetățenia unui stat membru. Cetățenia europeană presupune o legătură juridică între resortisanții unui stat membru și Uniunea Europeană, caracterizată prin drepturi (e.g. dreptul de a alege și de a fi ales în Parlamentul European, dreptul de a adresa petiții Ombudsmanului european, dreptul de inițiativă cetățenească europeană etc.) și, în sens formal, îndatoriri. În prezent, tratatele nu prevăd în mod expres obligații care incumbă cetățenilor europeni.
Referitor la pierderea cetățeniei unionale, pe cale jurisprudențială s-a stabilit că este de competența fiecărui stat membru să prevadă condițiile de dobândire și de pierdere a cetățeniei sale. (Problematizare Cauza 689/21). În urma Brexitului, Curtea a decis că pierderea statutului de cetățean al Uniunii este o consecință a decizie Regatului Unit de a se retrage din Uniune, iar nu a acordului de retragere. Problematizare Comunicat de presă nr. 101/23 Luxemburg, 15 iunie 2023.
Introduction:
Despite the recognized importance of parental satisfaction in pediatric physical therapy services, Romania currently lacks a standardized measure tailored to this context. This gap in the healthcare assessment framework complicates the ability of healthcare providers to gauge and improve service quality effectively. Understanding parents' satisfaction is crucial as it directly influences treatment compliance and outcomes. Parents play a pivotal role in the continuation and the effectiveness of the therapies prescribed for their children, making their perceptions a valuable indicator of the quality and success of physical therapy care.
Objective:
This study aims to explore the current landscape of Pediatric Physical Therapy in Romania by assessing the perceptions and satisfaction levels of parents whose children are or have been recipients of physical therapy services. This assessment seeks to fill the void in standardized tools and provide foundational data that could influence future healthcare practices and policy formulation.
Methodology:
To achieve the objective, this research utilizes an adapted version of the MedRisk Instrument for Measuring Patient Satisfaction with Physical Therapy Care (MRPS). The original 13-item MRPS was meticulously translated, back-translated, and then tailored to reflect the cultural and contextual nuances of the Romanian healthcare environment. This adaptation involved the creation of a parent-proxy version in the Romanian language to ensure relevance and comprehensibility. Recruitment for the study was conducted through convenience sampling, drawing participants from various regions to participate in an online survey.
Results:
The survey was launched on March 2, 2024, and involved a convenience sample of parents. It is anticipated that by the time of the conference, statistical analysis of the data, performed using JASP software, will be complete. This analysis will provide insights into the validity and reliability of the adapted instrument as well as initial perceptions of satisfaction among the participants.
Implications and Conclusions:
The adaptation of the MedRisk instrument and the preliminary findings from this study contribute to the literature on parental satisfaction in pediatric physical therapy in Romania. The results are expected to validate the adapted instrument’s potential to capture parental perceptions accurately, offering a promising pathway for ongoing research. Future studies could expand upon this work by refining the instrument and implementing it in broader surveys to enhance the comprehensiveness of data on rehabilitative pediatric care. This endeavor not only addresses a critical gap in the current research landscape but also sets the stage for enhanced therapeutic practices that are responsive to the needs and perceptions of families engaged in pediatric physical therapy.
Abstract
This paper aims to talk about unconditional love. We aim to explain what it means, what impact it has on the development and growth of the child. In what ways can we show children this kind of love? For the harmonious development of a child it is crucial to receive the unconditional love of parents, so that self-concept will not be affected. The lack of unconditional love has negative effects on both child and adult development. The article is based on an extensive bibliographic study, following various sources that you will find at the end, in the section dedicated to bibliography.

Abstract
I’ll talk about parental figures that take advantage of their kids in a way that should never be accepted. The four main forms of abuse are: physical, verbal, sexual and emotional. You’ll observe that I’ll point out one of the most common categories. Unfortunately, not everyone pays enough attention of the signs that can be considered serious mistreat, which later can lead to major problems affecting the welfare of the children. Through this article I want to raise awareness so the rest of the world knows how to identify the signs and how to help the little people.

The present paper aims to make a foray into the concept of rumination. When you repetitively and passively focus on the meaning, causes and consequences of negative emotions or on an unfinished problem you ruminate. Each of us has such repetitive thoughts, but rumination is excessive and has negative implications for mental and physical health. Rumination is a well-established risk factor for the onset of major depression and anxiety symptomatology in both adolescents and adults. We examined the rumination of anger and sadness in adolescents aged 14-18 years and students aged 18-45 years. We expect that female persons reported higher levels of both forms of rumination compared to male persons. Rumination prolongs and exacerbates negative feelings, reduces effective problem solving, and diminishes the willingness to engage in activities that induce positive affect.
The purpose of this article is to investigate the relationship between Educational Leadership and Self Determination Theory. Self-determination theory (SDT) is an comprehensive theory of human personality and motivation that focuses on how individuals interact with and rely on the social environment. SDT underscores the idea that people’s relationships and social contexts must involve and support their fundamental human needs for autonomy, competence, and relatedness. Additionally, this article includes a comparative analysis of the levels of personal and educational autonomy among leaders and followers, aiming to highlight the differences and motivate readers to aspire to leadership role.2
ABSTRACT
În acest studiu am introdus modelul sistemelor ecologice elaborat de Urie Bronfenbrenner pentru a analiza contextele de integrare actuale și necesitatea unei echipe integrate.
Principalul obiectiv al acestui studiu a fost analiza statutului de Shadow și necesitatea acestuia în programul de integrare socială a copiilor cu Cerințe Educaționale Speciale.

Miturile politice postmoderne dependente de imagini mai mult decât de naraţiune joacă totuşi acelaşi rol simplificator şi unificator ca şi cele arhaice încercând să ofere o interpretare consensuală complexităţii lumii. Construcţiile mitologice postcomuniste ne vorbesc mai mult despre imaginarul societăţii româneşti ieşite din comunism decât despre realitatea comunismului. Deşi pleacă de la nişte realităţi de netăgăduit, naraţiunile privitoare la acest regim sunt de cele mai multe ori nişte ficţiuni menite a oferi un sistem explicativ şi un mesaj mobilizator.
Această prezentare îşi propune să interpreteze structurile imaginarului postcomunist românesc prin analiza miturilor privitoare la epoca comunistă vehiculate în spaţiul public postdecembrist şi rolul memoriei colective în crearea şi transmiterea acestor mituri.

In the Romanian industry, liquidity and solvency are crucial aspects for evaluating the financial stability of a company. Liquidity indicates the immediate ability of an economic entity to meet its short-term financial obligations, while solvency reflects its ability to cover its long-term debts. These indicators are particularly relevant in Romania's fluctuating economic context, especially for the period 2019-2022, as they provide vital clues on a company's ability to face all financial challenges, possible market changes and avoid the risk of bankruptcy.
The analysis of the evolution of the financial performance of any economic entity is essential for the optimal understanding of financial health, allowing both the identification of essential trends and the factors influencing the company, as well as the making of strategic and informed decisions for its future. This study aims to evaluate this complex notion, on a specific company from the hotel and restaurant industry, according to the CAEN code, listed on the Bucharest Stock Exchange, having as a starting point the financial statements available for the period 2020-2022. With the help of the analytical-diagnostic methodology, we will finally be able to issue pertinent value judgments and finally we will be able to carry out a parallel analysis of the company's performance with the level of manipulation of the financial statements, applying two models established by the specialized literature.

Totalitatea schimburilor de bunuri economice, capitaluri, valute, tehnologie de vârf ce au loc între agenții economici din toate țările lumii definesc piata modială.
Piaţa mondială nu este o noţiune geografică, ci una economică. Ea reprezintă ansamblul tranzacţiiilor care au loc între agenţii economici de pe întreg globul.
Inteligența artificială (IA) reprezintă inteligența demonstrată de mașini, în contrast cu cea naturală manifestată de oameni și animale. Acest articol explorează contextul istoric, dezvoltarea și implicatiile societale ale IA. Începând cu munca crucială a lui Alan Turing în timpul celui de-Al Doilea Război Mondial la Bletchley Park, acesta urmărește evoluția cercetării în domeniul IA prin contribuțiile pionierilor precum Marvin Minsky și John McCarthy. Textul discută atât beneficiile potențiale, cum ar fi îmbunătățirea eficienței și productivității în diverse domenii, cât și provocările, inclusiv înlocuirea locurilor de muncă și preocupările legate de securitatea datelor, asociate adoptării rapide a IA. În ciuda acestor provocări, articolul subliniază impactul pozitiv semnificativ pe care IA îl poate avea asupra societății, de la îmbunătățirea diagnosticului medical la susținerea dezvoltării durabile și inovației tehnologice. Concluzionează prin pledoaria pentru reglementarea atentă și implementarea etică a IA pentru a maximiza beneficiile sale și a minimiza riscurile asociate.
Odată cu dezvoltarea internetului interacțiunea dintre oameni s-a intensificat, din păcate doar interacțiunea virtuală, interacțiune umană având de suferit. Comunicarea online este mult mai facilă și mai rapidă decât comunicarea face to face. Este mai simplu să trimitem un mesaj pe WhatsApp sau Facebook sau orice altă rețea socială decât să scriem o scrisoare. Cu toate aceste beneficii ale comunicării prin social-media apar și dezavantaje cum ar fi lipsa socializării directe faptul că nu ne putem privi interlocutorul, iar cel mai mare dezavantaj îl constituie degradare limbii române prescurtand cuvintele și folosind emoticoane pentru a transmite stări, emoții și trăiri.
Lucrarea dezvoltă tema reputației în mediul online, concentrându-se și pe comunicarea de criză. Vor fi analizate subiecte precum prezența pe internet, imaginea unei persoane sau organizații, metode de îmbunătățire și prezervare a reputației pozitive și metode de acționare într-o situație de criză care afectează reputația unei organizații, a unei persoane.
Încă de la începuturi, comunicarea politică reprezintă un maraton al persuasiunii aplicate asupra populației cu scopul de a strânge voturi și simpatie în detrimentul politicianului sau al întregului partid. În prezent, lupta politică și-a găsit frontul pe rețelele de socializare unde fără mari eforturi, omul politic își poate forma imaginea, exprima părerea și crea reclama după bunul plac, iar informația are deschidere la cel mai vast public, în așa fel încât fiecare promisiune fără temei și defăimare asupra concurenței să ajungă la cetățeni în acest an electoral.
Lucrarea se va axa atât pe faptul că marketingul pe social media a devenit esențial în era noastră cât și importanța conștientizării riscurilor și situațiilor de criză care pot să apară, împreună cu modalități de gestionare a acestora pentru a proteja reputația influencerilor. Am de gând să adaug exemple, atât din România cât și din străinătate, care să stârnească atenția ascultătorilor și să facă subiectul prezentat unul mai ușor de înțeles.

cursuri de vorbire în public, ca platforme principale în activitățile de vorbire în public.
During 2023, we conducted qualitative and quantitative research on the edaphic coleopteran fauna of the Sub Arini Park, located in the city of Sibiu, Romania. The aim of the study was to inventory the diversity and distribution of coleopteran populations in this urban park. The main objectives of the research included the identification of the species of coleoptera present in the park, the investigation of their ecological characteristics, as well as the analysis of preferred habitats and their variation in terms of time and space.
Between April and October of 2023, we placed a number of 17 soil traps on an area of 21.65 hectares, covering the entire area of the park. These traps were checked and lifted weekly to collect relevant data on the beetle populations. In total, we identified 26 species of coleopterans belonging to 8 families, totaling 2118 specimens.
Based on the data obtained from the faunal samples, we performed ecological analyzes for all investigated habitats, covering the vernal, summer and autumnal seasons. For each individual species, we have calculated ecological indices.

During the research period (2020-2023), the identification of the etiological agents detected, the prevalence of contamination, the distribution by age groups, residence and level of studies were pursued. The data were centralized in tables, using the percentage calculation method, and the results were plotted. Out of a number of 2,531 investigated patients, 39 positive were diagnosed for parasitosis 2020 (2.76%), 2021 (1.73%), 2022 (1.10%), 2023 (0.65), decrease probably due to the pandemic.
Green walls are walls covered in greenery, often called vertical gardens. The two main types are living walls and green facades. Green walls can have a strong role in biodiversity, they contribute to reducing the effects of urban heat islands, they increase carbon dioxide intake, overall increasing the quality of life in urban areas.
Green roofs are roofs covered in plants, having similar effects to green walls and often serving as community gardens.
The target of the study was highlighting the role of greenery found on green walls such as green facades and hedges in reducing temperature and humidity in the areas where they are located. Measurements were made on hedges such as Buxus semperviens or Ligustrum ovalifolium and on green facades consisting of common ivy, Hedera helix and Wisteria fluribunda.
The partial results demonstrate the support of the hypothesis. The temperatures measured on the green walls areas were on average lower by 0,6 degrees Celsius than those measured in the atmosphere and the humidity was lower by 2-3%.
Development of rivers in cities, sewers and bank constructions, can have a significant impact on local biodiversity. These interventions can lead to the destruction of natural habitats, the decrease of water quality and the isolation of plants and animal populations.
At the same time, improving water management and reintegrating natural areas into urban planning can contribute to preserving and restoring biodiversity in the urban environment.
The purpose of the research was to highlight the dynamics of soil microorganisms, in order to assess the microbiota quantitatively and qualitatively, by comparing two different soils in terms of location and origin, as well as by exposure to various factors that have an impact on soil quality.
Several types of analyzes were performed for the two types of soil. To carry out the microbiological analyzes on the soil samples, the method of the decimal dilution series of 9:1 soil extracts was used. The microbiological analyzes aimed in particular to identify the total number of germs, bacteria and fungi (yeasts and moulds). Physical analyzes of the soil consisted of checking temperature, moisture, pH/Eh and conductivity/Sa.
Efectele extractului apos de Salvia officinalis asupra diabetului zaharat de tip II și a hipertensiunii arteriale
Diabetul zaharat de tip II reprezintă o afecțiune caracterizată prin creșterea nivelului de glucoză serică, rezistență la insulină și carență de insulină. Apare atunci când glicemia (nivelul glucozei serice) este prea mare, ca urmare a obezității, lipsei de efort sau predispoziției genetice.
Hipertensiunea arterială este o afecțiune medicală pe termen lung în care tensiunea arterială este crescută în mod persistent. Hipertensiunea arterială, de obicei, nu provoacă simptome în sine, dar este totuși un factor de risc major pentru accident vascular cerebral, boală coronariană, insuficiență cardiacă, fibrilație atrială, boală arterială periferică, pierderea vederii și boală cronică renală.
Salvia officinalis este o plantă medicinală, folosită din cele mai vechi timpuri pentru tratamentul unor afecțiuni variate și fiind numită ,,iarba sfântă”. Extractele de S. officinalis au efect anti-tumoral și citostatic, anti-inflamator, antiseptic și hipoglicemiant.
Studiul își propune testarea influenței extractului apos de salvie asupra nivelului glicemiei în diabetul zaharat de tip II. Scopul acestui studiu este de a identifica posibilități de amliorare a stării de sănătate a bolnavilor de diabet prin admistrarea extractului de salvie simultan cu medicația antidiabetică.
Lotul de persoane monitorizate si testate, deși inițial lărgit (30) s-a stabilizat la 10 bolnavi de diabet zaharat tip II. Lotul de bolnavi a fost selectat în colaborare cu medicul diabetolog, care pe lângă medicația specifică a prescris si utilizarea ritmică a extractului apos de Salvia officinalis timp de 30 de zile. Premergător studiului toate cazurile au fost testate privind următorii parametrii fiziologici: glicemie, hemoglobina glicozilată (HbA1C), colesterol seric total, trigliceride, aspartataminotransferaza (TGO), alaninaminotransferaza (TGP), lipoproteine cu densitate mică (HDL), lipoproteine cu densitate mare (LDL).
În urma analizei rezultatelor, am concluzionat că extractul apos de Salvia officinalis a redus glicemia la 60% dintre pacienți, iar rezultatele analizelor precum hemoglobina glicozilată (HbA1C), colesterolul seric total și lipoproteinele cu densitate mare (LDL) s-au îmbunătățit semnificativ.
Multidrug-resistant bacteria is one of the most concerning health problems all over the world. Uncontrolled use of antibiotics and antifungals drives these phenotypes. Developing new combat strategies is crucial to prevent healthcare and humanitarian crisis. Potential strategies include essential oils, antimicrobial peptides, bacteriophage therapies, and nanoparticles. These strategies could offer an optimized alternative to antibiotics, transforming virulent microorganisms into avirulent ones, without major disruption to the normal microbiota or human body homeostasis.
In this study we focused on the antimicrobial potential activity of the essential oils, that were tested using different methods against Gram-negative, Gram-positive and fungal microorganisms.
Keywords: multidrug-resistant bacteria, essential oils, human health protection, antibiotics alternatives
This project explores the efficacy of DNA extraction from locally grown fruits in Romania, aiming to identify optimal candidates for genetic analysis. Seven fruits—plums, apples, pears, peaches, strawberries, grapes, and quince—were selected based on criteria such as diversity, water content, and DNA characteristics. The extraction process involved standardized methods, and the quantity of extracted DNA was evaluated visually due to equipment limitations. Results indicated that strawberries yielded the most DNA, followed closely by grapes, apples, and pears, while peaches, plums, and quince produced lower quantities. These findings align with hypotheses based on fruit characteristics. Suggestions for optimizing extraction protocols include enzyme incorporation and varying lysis buffer concentrations. The study's implications span education, scientific research, and practical applications in agriculture, conservation, and biotechnology. Detailed project timelines and references provide a comprehensive overview of the experimental process and outcomes.

Additionally, the potential of red mud for remediating contaminated soil is explored. The conclusions emphasize the need for urgent remediation strategies to protect the environment and the health of local residents.
The natural and anthropic impact on the water quality of the Sebeș River is analyzed in this study. Using data from previous reports and information about hydrological characteristics, we evaluated the chemical state of the water, identifying potential sources of pollution and concluding that overall, water quality is good. However, concentrations of nutrients in some sections reflect anthropic impact. For efficient water resource management, continuous monitoring, identification, and reduction of pollution sources, and community involvement in decision-making processes are recommended. These actions are essential for protecting and improving the quality of the aquatic environment and local life.

The project implements an urban traffic simulator, in a scenario with both vehicles and pedestrians. The user has the ability to place and remove traffic lights and pedestrian crossings, as well as decide the timing of the traffic lights. For simulation scenarios, the number of moving vehicles and pedestrians can be specified. The simulator offers options for saving, reloading, and accelerating the simulation. Each simulation scenario concludes with the generation of statistics (average speed of all vehicles, total time spent in traffic, etc.), based on which the impact of traffic control elements is analyzed. The simulation is conducted on a realistic map obtained from an "open data" file and rendered in Unity. The file contains real coordinates of streets and can represent any region in the world. The simulator can run on Windows 10+ and Linux operating systems.
The purpose of the simulator is to generate statistics based on which a decision-making algorithm, to be implemented, will generate recommendations for managing traffic lights aimed at reducing traffic congestion.
During a simulation, statistics are generated for each vehicle, highlighting its current state (moving or waiting), and at the end, the average speed at which it traveled the route is calculated. Also in the statistics section, the user can select road segments, on which the average speed during the simulation and the number of vehicles on that stretch in different time intervals are calculated.

The present longitudinal study investigated participants’ car use behavior for a week, by using objective mobility data collected with Google Location through participants’ smartphones. 48 residents of a large Romanian town provided their mobility data, together with their answers on a questionnaire. Several psychological, structural and contextual predictors of car use were investigated in a multilevel model with two levels. Present findings indicate that instrumental motivations such as distance needed to travel, the need to pick-up/drop-off children to/from school and the need to carry heavy objects have the largest influence on car use behavior. Additionally, access to alternative transport infrastructure and the strength of people’s car use habits also significantly influence the number of kilometers travelled by car. Psychological variables such as those described by the theory of planned behavior or norm activation model, together with weather variables such as wind speed, temperature and precipitations, did not directly influence car use behavior. Results contribute to a more comprehensive understanding of car use behavior and are relevant for policymakers and city planners in their attempts to shape a sustainable urban environment that is adapted to one of the greatest challenges of the present.

Many industries such as the healthcare industry, industrial safety and environmental monitoring require gas detection equipment. The precise and quick detection of various gases, including methane (CH4) is a very important factor in recognizing possible hazards, ensuring workplace safety and managing emissions. [1] Chemiresistive sensors based on conductive polymers such as polyaniline have shown great sensitivity, quick reaction time and adaptability, making them promising tools for gas detection at room temperature [2,3].
In this study, polyaniline (PANi) conductive polymer was selected due to its well-known adaptability to a variety of gases, including ammonia, hydrogen, and methane. [4] This polymer was synthesized via chemical polymerization of its monomer directly on the interdigitated gold electrodes and its properties have been further investigated using scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) to provide morphological and chemical information. Additionally, an in-house gas testing equipment was used to electrically characterize the developed sensor. Using a source-meter, the electrical characteristics of the sensor inside the gas chamber were examined while it was subjected to different CH4 concentrations ranging from 1 to 20 ppm.
In conclusion, the data acquired showed that the suggested sensor demonstrates a noticeable decrease in electrical resistance upon exposure to the analyte, indicating its high sensitivity to detect small concentrations of the analyte, as low as 1 ppm.

Engineering science, in the future, will contribute through creation to the promotion of national values, to the development of civilization, to economic progress. At the same time, the digital revolution allows even now, but especially in the future, new, innovative forms of access to knowledge. In this context, the authors of the article develop a new concept for Romania, of restoration, not so much through the measures applied to the monument as through the other aspects aimed at increasing their impact on the progress of civilization - on knowledge. The case studies identified by the authors argue this vision and also represent an opening in promoting the new attitude in the concept of restoration.
Abstract. As known, the principles of restoration and conservation have evolved from the past when restorers treated historical monuments as works of imagination, thereby creating new works during the restoration process, showing to the present observer a falsehood, a graft, and misleading the future researchers of the historical monument. Today, the restoration of historical monuments involves a fusion between the discipline of conservation (the mission of the restorer) and the new architecture (the vision of the architect), creating a new synergy that allows the past to be rediscovered in the present, for the future. It adds a new layer to the identity of the historical monument. The weight between conservation and innovation is variable, being determined by a lot of factors, specific to each historical building. The use of 3D scanning technology has revolutionized the way the restoration process is approached, allowing the specialists to capture detailed information about the building and create accurate models for the restoration process. The authors, based on thorough studies and research, develop in this article the relationship between the conservative approach of the restoration, that has the mission of preserving the authenticity and historical significance, and at the same time ensuring that the historical monument remains relevant and useful for contemporary society. This requires a futuristic vision of the architect, who seeks to integrate modern technologies and materials, while also preserving the authenticity of the historical monument. In this article, the authors will explore the use of 3D scanning technology in the restoration of historic buildings, focusing on 3 case studies, of historical buildings in Brăila, Romania.
In this article, the authors studied the way of transferring old queuing structures, many of which are historical monuments, in a vision of new concepts based on the maximum application of the 3D concept in calculation and the composition of constructions that respond the current requirements aimed at mechanical resistance and, but also in the concept imposed by the real conditions of climate change. The effects of climate change are increasingly visible in areas adjacent to the marine environment or flowing waters. In this context, such a structure must be calculated and realized based on new assumptions that complement the old traditional concepts. In this situation, the effect of water level variations, the aggressiveness of the marine environment, the increase in wind intensity, the temperature variations that often affect the ecosystem must be considered both in the new concept of these structures and in the rehabilitation solutions of the old ones special constructions. hydrotechnical.
Criza acută de locuințe coroborată cu cerințele și exigențele care decurg din reducerea emisiilor de gaze cu efect de seră impune o nouă viziune în concepția și realizarea clădirilor de locuit. În ultima perioadă materialele utilizate s-au caracterizat prin consumuri ridicate de energie, prin tehnologii poluante ale căror efecte sunt tot mai mult observabile prin efectele produse. În viziunea autorilor, reducerea emisiilor de carbon va reprezenta una din cerințele și necesitățile viitoarei generații de constructori. Utilizarea materialelor și tehnicilor tradiționale într-o manieră conceptuală funcțională va putea răspunde la noile politici de mediu dar și de confort locativ. Bazat pe acest concept autorii prezintă o serie de soluții utilizate la edificii remarcabile realizate din materiale locale prin metode și tehnici tradiționale actualizate astfel încât să satisfacă cerințele actuale de rezistență mecanică și stabilitate sau cele de estetic și funcțional.
New Urbanism is an urban planning concept developed in response to the problems caused by rapid urbanization and uncontrolled suburban expansion. It is characterized by an integrated and sustainable approach that addresses current challenges related to climate change, population growth, and limited resources. One of the main trends in contemporary urbanism is sustainable development, which involves designing cities to minimize resource consumption and reduce greenhouse gas emissions. Green buildings, the conversion of old buildings, the use of renewable energy, and efficient public transport are essential components of this model. The integration of green spaces and urban parks also contributes to improving air quality and provides residents with areas for recreation and relaxation. Moreover, technology plays a crucial role in the new generation of urbanism. Smart cities utilize information and communication technology to optimize urban infrastructure and services. Community participation is also a vital component of modern urbanism. Engaging citizens in the urban planning process ensures that their needs and desires are considered, thereby promoting social cohesion, equitable development, and the formulation of urban policies that reflect the community's aspirations. Urban mobility is integrated into urban planning to reduce reliance on automobiles and to create more accessible, healthier cities, offering faster and more reliable public transport services. Authors, based on extensive studies and research, develop the concept of the new generation of urbanism, which focuses on sustainability, technological innovation, and community participation. The goal is to create resilient, efficient, and environmentally friendly cities.
The use of hemp-based eco-concrete is now a real option for any beneficiary to consider when choosing materials for new construction or energy retrofitting of existing buildings. Rising energy costs, climate change, pollution and comfort requirements have led to the introduction of legislation to reduce the environmental impact of the construction industry. The European Union's Sustainable Development Goals aim to achieve climate neutrality by 2050. Hemp is valuable both as a plant from which seeds and oil can be obtained for food and as a raw material in the form of chopped stalks from which thermal insulating building materials with a negative impact on the CO2 balance can be made. This is why hemp, and in particular hemp concrete, plays an important role in reducing climate change and has been included in the European Commission's recommendations as an effective means of achieving the proposed targets.
The increasing demand for environmentally friendly materials has led to a wide range of options from which architects and designers can choose to meet the financial constraints of the client and the requirements of design and construction regulations for both residential and socio-cultural buildings. In this paper, the optimisation criteria are established and the calculation method for determining the compositions is presented in order to make the consumption of hemp raw material more efficient, to reduce the consumption of air and hydraulic binders, to reduce the consumption of water and additives for the production of hemp concrete. This is necessary because the raw material has a bulk density that varies between 87 and 139 kg/m3, depending on the diameter of the hemp stalks at the base of the soil. The morphological differences of the plants, as well as the soil and climatic conditions, determine the grain size characteristics, which can influence the thermo-mechanical properties of the reinforced material. The amount of binder required in the mix depends on the particle size distribution.
The optimisation of the compositions is carried out according to the criteria that determine the maximum limits of the quantities of binding agents used, so that the material obtained at the end has the properties specific to the construction element designed and the consumption of raw materials is ecologically and economically efficient. Although hemp is a renewable resource, it is important that it can be used rationally.
This paper is based on a case study conducted at the ancient Kastri-Pandosia site in Greece. The purpose of the study was to use aerial thermal imaging in order to detect differences in composition, density and moisture content, materials on and below the ground surface based on different rates of absorbtion, emition, transmition and reflection thermal infrared radiation. The most impressive result was obtained in the area corresponding to the public Hellenistic building where the lack of vegetation allowed the thermal camera to detect a shallow buried fragment of structure.

The future of civil engineering in the opinion of the authors will be determined by the structural design, by the materials used but also by the scientific concerns of the manufacturing industry materials . In the view of the authors, the structural concept has in mind the realization of some constructions that meet the main requirements stipulated by the legislation in force, requirements aimed at mechanical resistance, safety and function so that they fully respond to the function for which they were designed. Construction materials will be high performance materials with superior mechanical strength, i.e. high-performance concretes, concretes of high durability specific to the built environment. With reference to the manufacturing industry, the authors have in mind the industrial processes aimed at reducing dioxide emissions carbon, processes that will properly ensure the protection requirements the environment. A particularly important aspect in the opinion of the authors is identification energy independent solutions. The work represents case studies, opinion proposals based on scientific research that can initiate new research directions.
The constructions related to the oil industry offer a wide range of case studies for civil engineering due to the fact that they entail different types of structures adapted to various products resulting from both the exploitation process and the refining process.
As known, constructions can house products with considerable density, as well as volatile substances, each presenting specific vulnerabilities related to storage conditions. Even though petroleum is not chemically aggressive, derived oils as well as the condition of bottled products can be sources of risk for explosions and fires.
In the current conditions generated by climate change, new requirements and demands arise that the civil engineering specialist must take into account. The authors develop the risks generated as well as a series of measures with modern procedures for appropriate operating conditions.

Abstract Problematica acestei lucrări se referă la conceptul promovării valorilor istorice arhitecturale în contemporanitatea texturii urbane din Dobrogea prin aplicarea în conceptul clădirilor moderne a unor elemente valoroase care au constituit, la un moment dat, caracteristica arhitecturală a zonei Dobrogei. Replicarea/inspirarea din frumoasele și elegantele forme reprezintă o conservare proactivă a patrimoniului. Construirea unor clădirile noi, cartiere, orașe sau chiar întregi zone poate fi inspirată din formele celor vechi și adaptate modernității și necesităților funcționale din zilele noastre. În vremea Imperiului Otoman existau bazaruri și karavanseraiuri. Un bazar era o clădire sau un complex de clădiri destinate comerțului, adevărate temple ale negoțului, comparabile ca dimensiuni, funcționalitate și concept comercial cu mall-urile actuale. Tot în vremea otomană un karavanserai era un palat pentru caravane, un complex de clădiri medievale alcătuit din camere de odihnă, loc de luat masa, bucătărie, magazii, grajduri, fierărie, potcovărie și alte ateliere, și deosebit de important, surse de apă potabilă. În Dobrogea otomană multe karavanseraiuri aveau dimensiuni mari, uneori chiar și etaj. Bazarurilor și karavanseraiurilor le era caracteristică dezvoltarea pe orizontală și intrările individuale. Acest tip de clădire poate constitui o veritabilă sursă de inspirație pentru organizarea funcțională a unor clădiri moderne. Recenta situație pandemică a arătat eficiența funcțională a spitalelor pavilionare, a unităților locative și de cazare, grădinițelor, școlilor, magazinelor, piețelor, etc. cu intrare individuală. Chiar dacă dezvoltarea pe orizontală nu este proprie clădirilor din orașele moderne, nu trebuie să uităm că oamenii se simt mai confortabil
Urban biodiversity is necessary to ensure the good functioning of all the mechanisms of the living world. This presentation has as reference points the highlighting of several species from the Lamiaceae family that could be introduced into urban biodiversity, as well as the invertebrate species that were in symbiosis with them, in order to create an optimal functioning system. We also want to highlight the many medicinal and gastronomic uses of these wonderful plants.
As the title says, rosaceae can be very useful in cities. Such as shading public places by planting hanging roses. Other types of rosaceae produce fruit which helps the birds with food. Also purifying the air and blocking dust.
Plants are generally perceived as things that should be beautiful or exist only for the pleasure of the eye, but in nature there are also plants that help us maintain our health and that improve the taste of food.
