OSPOSOBLJENOST NASTAVNIKA OSNOVNIH ŠKOLA ZA REALIZACIJU NASTAVE NA DALJINU I NJIHOV UČINAK TOKOM PANDEMIJE VIRUSA KORONA
Authors: Dakić Jovana , Andevski Milica
Published: November 2022

Pojavom virusa korona i proglašenjem vanrednog stanja u našoj zemlji nastava se iz učionice premestila na televizore, u različite kompjuterske programe, na internet i društvene mreže. Na test je stavljena informatička pismenost učesnika nastavnog procesa, kao i njihova sposobnost da informaciono-komunikacionu tehnologiju implementiraju u nastavu i upotrebljavaju je na najkvalitetniji mogući način. U skladu sa tim je bilo neophodno ispitati osposobljenost učesnika nastavnog procesa za realizaciju nastave na daljinu. Cilj ovog istraživanja je bio ispitivanje osposobljenosti nastavnika osnovnih škola za realizaciju nastave na daljinu. Upotrebom deskriptivne naučno-istraživačke metode analizirani su podaci prikupljeni tehnikama skaliranja i anketiranja. Rezultati istraživanja su pokazali da su nastavnici imali pristup adekvatnoj opremi i tehničkoj podršci, da su bili zadovoljni nastavom na daljinu, ali da se nisu osećali spremno za prelazak na nastavu na daljinu. Kao najveću poteškoću sa kojom su se suočavali tokom realizacije nastave na daljinu nastavnici su izdvojili komunikaciju sa učenicima i nedostatak povratne informacije. Zaključuje se da je komunikacija između nastavnika i učenika jedan od glavnih aspekata nastave na daljinu koji je neophodno detaljnije istraživati. Doprinos istraživanja se ogleda u boljem razumevanju perspektive nastavnika u oviru nastave na daljinu, kao jedne od osnova za unapređivanje ovakvog vida nastave.

Authors: UYSAL Derya
Published: November 2022

This study was conducted so as to reveal how pre-service ELT teachers’ learning style and motivation are associated. 198 pre-service teachers enrolled in the ELT department of Alanya Alaaddin Keykubat University in Turkey took part in the study. Data of the study was gathered via two research instruments that are Academic Motivation Scale and Learning Styles Inventory III. The scales were delivered to the pre-service teachers during tutorials in early first semester, Jan-Feb, 2022. Expected relationships in the hypotheses formulated were tested via Chi square test analysis in SPSS. According to the results, 4 hypotheses were confirmed; however, the second hypothesis was rejected. Therefore, the results revealed that gender differentiated motivation and learning styles of ELT student teachers. However, although year level differentiated motivation, it did not differentiate learning styles of ELT pre-service teachers. Last, motivation of ELT pre-service teachers differentiated their learning style. Results of the study are significant in terms of filling in the gap regarding the research on how motivation relates to learning styles of pre-service teachers.

Ülkelerin lojistik performanslarının birbirlerine uyumuyla gerçekleşecek ülkeler arasındaki lojistik konularındaki ilişkiler ile ülkeler lojistik performanslarını artırabilmektedirler. Bu kapsamda ülkelerin lojistik performanslarına göre gruplandırılması büyük önem arz etmektedir. Buna göre araştırmada en son ve güncel olan 2018 yılı için Lojistik Performans Endeksi (LPI) raporunda yer alan 160 ülkenin LPI bileşenlerine ait değerler üzerinden K-ortalamalar kümeleme analizi ile söz konusu ülkeler gruplandırılmıştır. Bulgulara göre, tüm LPI açısından en fazla performans gösteren 1’inci kümedeki ülkeler olmuştur. Diğer kümedeki ülkelerin LPI sıralaması 2’inci küme, 4’üncü küme ve 3’üncü küme ülkeleri olarak tespit edilmiştir. Başka bir bulguya göre, 1’inci, 2’inci, 4’üncü küme ülkelerine en uzak olan küme ülkelerinin 3’üncü küme ülkeleri oldukları gözlemiştir. Dolayısıyla kümeler içinde en ayrışık küme ülkelerinin 3’üncü küme ülkeleri olduğu tespit edilmiştir. Ayrıca 2’inci ve 4’üncü küme ülkeleri diğer küme ülkelerine göre tüm küme ülkelerin küresel anlamda lojistik kültürünü daha iyi temsil etmelerinden dolayı hibrid küme ülkeleri niteliği taşıdığı belirlenmiştir. Bunların dışında, genel anlamda lojistik performanslarının diğer ülkelere kıyasla az olması kapsamında 3’üncü küme ülkelerin en ayrışık olmasından dolayı 3’üncü küme ülkeleri diğer küme ülkeleri ile lojistik anlamda uyum sağlamak için lojistik performanslarını artırmaları gerektiği sonucuna ulaşılmıştır. Bununla beraber ülkelerin lojistik performanslarını artırmaları için 1’inci küme ülkelerine en yakın olan 2’inci, 2’inci küme ülkelerine en yakın olan 1’inci, 3’üncü küme ülkelerine en yakın 4’üncü ve 4’üncü kümeye en yakın olan 2’inci küme ülkelerinin birbirleri ile lojistik konularında işbirlikleri ve ortaklıklar sağlamaları gerektiği değerlendirilmiştir.

Com exceção da ideia de igualdade (de acesso aos recursos das TDICs), seguida pelas ideias de praticidade/facilidade e afetividade, questões que expressam todas as demais categorias tiveram grande concordância entre os participantes. É preciso socializar os condicionantes históricos que constituem o fetichismo tecnológico, desenvolvendo entre os docentes possibilidades de relações sociais articuladas e organizadas, combatendo pressões mercadológicas e construindo meios de resistência que superem a reprodução das relações sociais alienadas.
Ventricular Septal Rupture (VSR) in Post-Acute Anterior Myocardial Infarction Patients : A Case Series
Authors: Kawilarang Ken Christian , Hermawan I Kadek Herry , Hartono Febryanti
Published: November 2022

Case Summary: We present 2 cases of post-STEMI VSR. They had anterior AMI without reperfusion therapy because of patient delay and limited resources. Thereafter apical VSR occurs on 5th day. VSR was suspected because of sudden hemodynamic deterioration and new holosystolic murmur (Grade III/VI) at left parasternal line of fourth-fifth ICS. Then it was confirmed by echocardiography. Both patients underwent hemodynamic stabilization while waiting for surgical therapy. Unfortunately, they deceased because of cardiogenic shock accompanied by other comorbidities. Discussion: VSR causes shunt from left to the right ventricle, which overloads the RV, leading to cardiogenic shock. The peak incidence of VSR in the first 24 hours or 3-5 days post-AMI. This fits both of our cases. VSR occurs in total coronary occlusion, which then causes coagulation necrosis in the ischemic area, characterized by neutrophils that trigger apoptosis and lytic enzymes, so that septum becomes thin, brittle then ruptures. VSR is most common in anterior AMI and the defect is at apical septum, as in our patients. Definitive therapy for VSR is surgical closure, but the best timing is still under debate. This article is expected to make us more aware of post-AMI VSR, so we can quickly diagnose and promptly treat the patients with multidisciplinary approach. This is very important to optimize patient’s outcomes even in limited resources area.

Published: November 2022

High-entropy alloy (HEA) catalysts have recently attracted worldwide research interest due to their promising catalytic performance. Most current studies focus on designing HEA catalysts through trial-and-error methods. This produces scattered data and is not conducive to obtaining a fundamental understanding of the structure-property-performance relationships for HEA catalysts, thereby hindering their rational design. High-throughput (HT) techniques and machine learning (ML) methods show significant potential in generating, processing and analyzing databases with a vast amount of data, providing a new strategy for the further development of HEA catalysts. In this review, we summarize the recent literature on HT techniques for HEA synthesis, characterization and performance testing. We also review the ML models that are used to process and analyze existing databases to accelerate the discovery of HEA catalysts. Finally, the potential challenges and perspectives of HT techniques and ML models are presented to accelerate the discovery of new HEA catalysts and promote their development.

Published: November 2022

This study aimed to examine religion-based nationalism in popular American and Indonesian films. The subjects of this research were American and Indonesian films from 1915-2020. This research used a mixed qualitative and quantitative research with content analysis approach. The findings of this study indicated that the discourse of religious nationalism was constructed in popular American and Indonesian films to carry out the practice of inclusion and exclusion of certain groups. The results of the analysis showed that religious nationalism in American films was dominated by Christian nationalism, while religious nationalism in Indonesian films was dominated by discourses of Islamic nationalism. Both American and Indonesian films were against the ideology of communism, but American films were dominated by exclusive nationalism, while Indonesian films were mostly inclusive. American films also tended to show Islamophobia while Indonesian films positioned Islam more as a spirit of religious nationalism. This research has theoretical implications for increasing studies on nationalism which always appears and strengthens in films as a form of mass communication.

Dynamic Realistic Failure Process Analysis (DRFPA) is a numerical software based on FEM it is firstly validated by comparing with the experimental test. Such validation is carried out under two consistent concrete specimens under uniaxial compression. After validation, DRFPA is used to study the influence of two parallel pre-existing crack inclination angles on the fracture of concrete under dynamic loads. The evolution of wing cracks and secondary cracks is investigated by observing the initiation, coalescence, and propagation of them. Meanwhile, the relationship between failure mode and inclination angles is discussed via analyzing the acoustic emission events. Finally, it is concluded the relationship between inclination angles of pre-cracks and performance/stability of concrete structure.
Freely Available LiDAR-based Digital Terrain Model (DTM) Uncovers the Heart of the Dacian World
Authors: Pețan Aurora , Hegyi Alexandru
Published: November 2022

Throughout history, the unique Dacian landscape has aroused the imagination of many. For decades, researchers have been fascinated by the magnificent structures the Dacians built and how they altered the mountains to their advantage. Dacian sites, despite their grandeur, remain mostly unknown due to their position deep within Romania's vast forests, generally in remote regions and hidden from the naked eye. Ground exploration in densely forested mountain regions is extremely difficult, and even if such campaigns existed, they would be insufficient to provide a comprehensive picture of the Dacian world. The lack of high-resolution remote-sensing data for wide areas made big-scale assessments of the landscape impractical. This is about to change, as new large datasets of LiDAR-derived digital elevation models, covering the entire heart of Dacian world, are now freely available. This paper reports on one of the most recent freely available LiDAR-based high-resolution digital elevation models in Romania, its impact on Romanian mountain archaeology, and how this can shape future research directions in understanding the Dacian landscape.

Arf-like Protein 2 (ARL2) controls Microtubule Neogenesis during Early Postnatal Photoreceptor Development
Authors: Gerstner Cecilia D , Reed Michelle , Dahl Tiffanie , Ying Guoxin , Frederick Jeanne M , Baehr Wolfgang
Published: November 2022

Arf-like protein 2 (ARL2) is a ubiquitously expressed small GTPase with multiple functions. In cell culture, ARL2 participates with tubulin cofactor D (TBCD) in the neogenesis of tubulin αβ-heterodimers, the building blocks of microtubules. To evaluate this function in retina, we conditionally deleted ARL2 in mouse retina at two distinct stages, either during embryonic development (retArl2-/-) or after ciliogenesis specifically in rods (rodArl2-/-). retArl2-/- retina sections displayed distorted nuclear layers and a disrupted microtubule cytoskeleton (MTC) as early as postnatal day 6 (P6). Rod and cone outer segments (OS) did not form. By contrast, rod ARL2 knockouts were stable at postnatal day 35 and revealed normal ERG responses. Cytoplasmic dynein is reduced in retArl2-/- inner segments (IS), suggesting that dynein may be unstable in the absence of a normal MTC. We investigated microtubular stability in the absence of either ARL2 (retARL2-/-) or DYNC1H1 (retDync1h1-/-), the dynein heavy chain, and found that both the retArl2-/- and retDync1h1-/- retinas exhibited reduced microtubules and nuclear layer distortion. The results suggest that ARL2 and dynein depend on each other to generate a functional MTC during early photoreceptor development.

Plant diseases are among the major factors affecting plant productivity. Biological control of plant diseases is preferred over chemical control as it is environment-friendly, cost-effective, and sustainable. Among many microbes capable of providing biological control of plant diseases, probiotic Bacillus species are most promising as they can survive in adverse conditions, provide plants with a wide range of benefits including protection from phytopathogens. Wheat blast caused by Magnaporthe oryzae Triticum pathotype (MoT) has emerged as a potential threat to global wheat production. Due to unreliability of fungicides and limited cultivar resistance, we aimed to screen and identify potential antagonist bacteria collected from internal tissues of rice and wheat seeds to determine their in vitro and in vivo inhibitory effects against MoT. Dual culture and seedling assays were performed to evaluate the efficacy of probiotic bacteria. Out of 170 bacterial isolates, three bacteria (BTS-3, BTS-4, and BTLK6A) were screened as potential antagonists against MoT in vitro. Artificial inoculation at the seedling stage showed that the isolates BTS-4, BTS–3, and BTLK6A reduced 89, 88, and 85% of wheat blast disease severity, respectively, compared to mock-inoculated control. The bacterial isolates were identified as Bacillus subtilis (BTS-3) and B. velezensis (BTS-4 and BTLK6A) through genome phylogeny. The whole genome sequence of these three bacterial strains decoded a number of orthologs to intrinsic genes of antimicrobial peptides, antioxidant defense enzymes, cell wall degrading enzymes, compounds involved in the induction of systemic resistance (ISR) in host plants, and volatile compounds to make them promising biologicals to control MoT in wheat. Combined data of in vitro and in vivo along with genome analysis suggest that Bacillus spp. suppress the destructive wheat blast disease likely through antibiosis and ISR in the host plants. Further field evaluation and characterization of antimicrobial compounds are needed for a better understanding of the mode of action and practical recommendation of these bacteria for wheat blast control in the farmers’ fields.

Rapid spread of African swine fever virus (ASFV), causing severe disease with often high fatality rates in Eurasian suids, prevails as a threat for pig populations and dependent industries world-wide. Although advancing scientific progress continually enhances our understanding of ASFV pathogenesis, alternative transmission routes for ASFV have yet to be assessed. Here, we demonstrate that ASFV can efficiently be transferred from infected boars to naïve recipient gilts through artificial insemination (AI). In modern pig production, semen from boar studs often supplies many sow herds. Thus, the infection of a boar stud presents the risk of rapidly and widely distributing ASFV within or between countries. Daily blood and semen collection from four boars after intramuscular inoculation with ASFV strain ‘Estonia 2014’ resulted in detection of ASFV genomes in the semen as early as 2 dpi, in blood at 1 dpi while semen quality remained largely unaffected. Ultimately, after insemination with extended semen, 7 of 14 gilts were ASFV positive by 7 days post insemination, and all gilts were ASFV positive by 35 days post insemi-nation. Twelve out of 13 gilts aborted at the onset of fever. A proportion of fetuses originating from the remaining gilt showed both abnormalities and replication of ASFV in fetal tissues. Thus, we present evidence for the efficient transmission of ASFV to gilts via AI and also to im-planted embryos. These results underline the critical role that boar semen could play in ASFV transmission.

Service for assigning a UDC code to mathematical articles based on semantic technologies
Authors: Almukhametov Damir Albertovich , Nevzoova Olga Avenirovna
Published: November 2022

Classification of documents with the assignment of classifier codes is a traditional way of systematizing and searching for documents on a specific topic. The Universal Decimal Classification (UDC) underlies the systematization of knowledge presented in libraries, databases and other information repositories. In Russia, UDC is an obligatory attribute of all book production and information on natural and technical sciences. The choice of classification codes is associated with the analysis of the structure of the classifier tree and is traditionally decided by the author of a scientific article. This article proposes a solution for automating the assigning the UDC classification code for a mathematical article based on a special resource - the OntoMathPro ontology for professional mathematics, developed at Kazan Federal University. An approach to solving the problem is to create "code maps" for each classifying code in the UDC tree in the field of mathematics. Under the "code map" is meant a weighted set of all extracted, with the help of OntoMathPro ontology, mathematical named entities from the collection of articles with a given UDC code. The creation of "code maps" is based on the hypothesis that the choice of the UDC code is determined by a certain set of classifying features that can be represented by classes from the OntoMathPro ontology. The proposed hypothesis was tested and confirmed in the paper.

Method for Clarifying the Affiliation of Authors of Scientific Documents Based on Requests to the Semantic Web
Authors: Gafurova Polina Olegovna , Lipachev Evgeny Konstantinovich
Published: November 2022

In accordance with the xml-schemes of aggregating mathematical libraries, metadata sets must contain information about the scientific organization in which the study was conducted. Currently, this information is formalized as an affiliation of the authors. Affiliation is a mandatory attribute of a modern scientific publication. The affiliation may be incomplete and may contain outdated information. This does not allow to form the required set of metadata. In this paper, we propose methods for refining and replenishing the metadata of documents of electronic mathematical collections. We use the open Web-resources for refining and replenishing the authors' affiliation components. Using the software tools of the metadata factory of the Lobachevskii Digital Mathematical Library, the affiliation block is extracted, its components are parsed and analyzed. Semantic links of affiliation components with network information objects are created using the system of requests to open data sources developed by us. This made it possible to refine the metadata based on the subsequent analysis of the affiliation components. In the case when the necessary data is missing in the article, we replenish the components of the affiliation.

Supercompilation and partial evaluation are still not widely used in practice. Why and what to do?
Authors: Klimov Andrei Valentinovich
Published: November 2022

Such methods of metacomputation as supercompilation and partial evaluation appeared around half a century ago. Since then, they have fruitfully developed, deep scientific results were achieved, many software prototypes were created. However, they are still not used in the practice of programming, although their authors foresaw a great prospect for them to automate programming and expected rapid achievement of the goals. What's the big deal? We consider the history of programming from the point of view of the evolutionary theory of metasystem transitions by V.F. Turchin in order to reveal the origins of metacomputation methods and their place in the overall picture. We note that unlike software tools that were easily put into practice, such as, for example, optimizing compilers, these methods could not be implemented in such a way that they could be used automatically, because they contain too many points of choice of solutions, options, degrees of freedom that the machine cannot resolve without human assistance. For further progress to practice, we propose to pay special attention to embedding metacomputation tools in modern programming environments and developing and designing convenient human-machine interfaces, where a person will remain the top-level metasystem that makes creative decisions. In addition, we propose to include supercomputers in the arsenal of software developers' tools, including metacomputation, as it happened in applied engineering fields, but for some reason the development of effective and reliable programs for critical applications is not considered to justify the use of supercomputers.
Should there be a national bibliographic database
Authors: Polilova Tatyana Alekseevna
Published: November 2022

Electronic Scientific Library eLibrary.ru And the Russian Science Index of Citation (RSIC) could well become the basis for creating a National Bibliographic Database. But to do this, the RSIC should have regular monitoring of the completeness and reliability of statistical and bibliometric indicators of journals, the quality of procedures for selecting reference groups of journals for building thematic ratings. We welcome the creation of an independent, open, permanent analytical structure that would monitor the quality of scientific products uploaded to the RSIC at a meaningful level, and the adequacy of the constructed RSCI ratings.

Published: November 2022

Problems of co-authorship in mathematical articles were studied on the basis of journals data stored in the All-Russian mathematical portal Math-Net.Ru for the period from 2000 to 2020. The investigation shows that the most articles (more than 59%) are written by a single author, 39% of articles are written by a group from 2 to 4 co-authors. 2% of articles correspond to scientific groups consisting from 5 to 44 co-authors. Such a structure of coauthorship shows that the known tendency of deliberate growing co-authorship does not correspond to our object of investigation. We show that the main features of the co-authorship graph, such as a fraction of the vertices as a part of the maximal connected component, diameter and the average path length are stabilized once the number of co-authors reach 4. Unlike the recommendations to allocate articles written by more than 10 co-authors to a separate category, in our work we can allocate publications written by 5 co-authors to such a single category.
Information Retrieval for Texts with Formulas
Authors: Korukhova Yulia Stanislavovna , Kriger Kseniia Pavlovna , Riazanova Evgeniia Borisovna
Published: November 2022

Nowadays a large number of scientific articles, research texts and books have been converted into digital form and published on open-access web sites. Formulas are an important component of research works, especially in mathematics, in natural sciences and in engineering disciplines. But most of the well-known modern search engines do not implement mathematical retrieval of texts from formulas. A mathematical search engine could solve many problems for authors doing some research and also for educational purposes also. In this paper, an approach to creating a mathematical search system for collections of documents, including those containing scanned images, is proposed: software tools and libraries are selected that allow them to be automatically translated into a structured form with possible error corrections. The paper presents a method for constructing an index and a fuzzy search algorithm. The proposed approaches are implemented in a prototype software system.

Authors: Ahmad Mousa Numan , Othman Ghadeer A.
Published: November 2022

Effects of dietary fat type on serum lipids and gut microbiota in cholesterol-fed rats were investigated. Forty-eight male Wistar rats were assigned (8/group) into three cholesterol-free (control) diets containing Corn Oil (CO), Sheep Tallow (ST) or Olive Oil (OO) or three cholesterol-supplemented (experimental) diets (COC, STC, OOC) and given ad libtium for nine weeks. Serum lipids, atherogenic indexes and several biological parameters were determined. Total Bacterial Counts (TBC) and seven bacterial groups were assessed. High-density lipoprotein cholesterol was higher (p<0.003) in CO (89.9 ± 6.5 mg/dl) and OO (80.9 ± 3.0 mg/dl) than ST (55.9 ± 4.3 mg/dl). Higher (p<0.05) total cholesterol and atherogenic coefficient were respectively found in OOC (131.4 ± 9.9 mg/dl, 1.20 ± 0.03 mg/dl) and COC (113.6 ± 10.6 mg/dl, 1.46 ± 0.35 mg/dl) than OO (96.4 ± 2.6 mg/dl, 0.19 ± 0.03 mg/dl) and CO (93.6 ± 2.6 mg/dl, 0.04 ± 0.03 mg/dl), but not in STC (95.8 ± 6.5 mg/dl, 0.70 ± 0.20 mg/dl) versus ST (87.0 ± 7.8 mg/dl, 0.60 ± 0.06 mg/dl). Neither fat nor cholesterol affected body weight, food intake, Bacteroidetes, Clostridium cluster IV, Lactobacillus, and Prevotella. Total Bacterial Count, Clostridium Coccoides-Eubacterium rectalae and Bacteroides were respectively higher (p<0.001) in ST (74.0 ± 20.0, 53.1 ± 8.5, 103.6 ± 32.3) than OO (24.8 ± 3.1, 18.9 ± 5.8, 32.3 ± 15.5). Bacteroides was higher (p<0.05) in ST (103.6 ± 32.3) than COC (38.7 ± 7.8), and STC (97.2 ± 13.5) than OO (32.3 ± 15.5) or COC (38.7 ± 7.8). Firmicutes and Clostridium Coccoides-Eubacterium rectalae were respectively lower (p<0.05) in STC (15.3 ± 1.2, 19.0 ± 4.3) and COC (19.0 ± 2.8, 14.4 ± 1.5) than ST (30.3 ± 4.7, 53.3 ± 8.5) and CO (32.7 ± 2.8, 33.0 ± 7.8), but not in OOC (23.5 ± 3.7, 34.4 ± 6.0) versus OO (25.3 ± 4.7, 18.9 ± 5.8).In conclusion, dietary fat and cholesterol alter serum lipids and gut microbiota in an interaction that is likely to have clinical connotations in cholesterol-related disorders.
Carotenoids: Source of Food Colour and its Benefits
Authors: K. Naganandhini , S. Swathisri , Palaniswamy Radha
Published: November 2022

Food colour or food additives are widely used in food industries, to enhance the organoleptic (colour, flavour, appreance, taste and texture) quality to food. To protect and increase the shelf life of food, additives are incorporated into it, normally food additive or food colorant from synthetic origin, mostly used in food industry. Colours like yellow, orange, red, green etc. are highly preferred in soft drinks, candies, bakery products etc. which carries some adverse effects on human health such as allergic reactions, hyperactivity, carcinoma etc. An alternative is to use natural food colorant/additive from natural sources in the form of carotenoids which can be incorporated into food with medicinal value or health benefits.
Prevalence of Non-Alcoholic Energy Drink Consumption among University Students in Turkey
Authors: Son Nazan
Published: November 2022

The global consumption of Energy Drinks (EDs) has been increasing over recent years. The aim of the present study is to determine the prevalence of EDs consumption among university students, and to investigate the relationship between their eating habits and lifestyles. This was a single-center, cross-sectional study and conducted with 705 students receiving university education on health care at Afyon Kocatepe University, in Western Turkey. Data was collected using the face-to-face interviewing technique. The normally-distributed continuous variables obtained from independent measurements were analyzed using the independent samples 't' test and non-normally distributed data was analyzed using the Pearson chi-square test. Of the 705 students included in the study, 226 (32.1%) were males and 479 (67.9%) were females. The mean age was 20.76 ± 1.89 years (min-max: 18-32). Of all the students, 28 (39.9%) were found to consume ED. Students who did not consume EDs had healthier dietary habits, exercised more regularly, and afforded more time for social activities. The findings of the present study indicated that the students had limited information on the contents of EDs and the reasons for use. Students who had not consumed EDs were found to have healthier eating habits and more regular studying programs. This study should be replicated in larger samples and based on findings various educational programs should be designed to increase awareness among students on ED consumption.

Published: November 2022

Alginate is a phycocolloid present in the cell walls of brown macroalgae. Industrial and commercial applications of alginate secure global recognition in food, textile, cosmetic and medical industries. Exploring the new opportunities for the application of sodium alginate is the need to be enlightened. Systematical study and comparison of different extraction methods and their effects on physiochemical properties is to be explored. Sargassum cinctum needed for the study was collected from Mandapam, Gulf of Mannar, Tamil Nadu, India. The samples were washed, dried, powdered and used for polysaccharide extraction. S. cinctum samples were treated and extracted using three different methods. Extraction yield, moisture content, optical characteristics, solubility and structural characterization by FT-IR were carried out for sodium alginate obtained by different extraction methods respectively. Difference in the characteristics and properties of sodium alginate obtained by standard extraction methods paves way for selecting the right method based on the properties for the end application and in the new arenas.
Study on Clinical Features and the Reproductive Hormonal Profile in Normal, Overweight and Obese Polycystic Ovarian Syndrome Women of Selected Age Group
Authors: S. Velvizhi , S. Annapurani
Published: November 2022

The objectives of the present study are to compare the clinical features among normal and PCOS women and to assess the reproductive hormonal profile of normal and PCOS women of the overweight and obese group. The normal and PCOS women were subdivided into three groups, group 1-healthy women with BMI 18.5- 24.99 (n=10), group 2 PCOS with BMI 25-29.9 (n=11) and group 3 PCOS with BMI >29.9 (n=10). The prevalence of menstrual irregularity, acne, hirsutism and obesity are the major clinical manifestations of PCOS women than the normal women of the same age group. The levels of testosterone increased and estradiol level decreased in the PCOS subjects of both overweight and obese groups. These observations in the study strongly support the presence of hyperandrogenism in PCOS women and favors all the associated clinical features. The results also clearly demonstrated the increase in body mass index reflecting a negative impact on the reproductive outcome in PCOS.
