ON THE DEPENDENCE OF TURBULENT VISCOSITY ON THE REYNOLDS NUMBER FOR FLOW IN PIPES
Authors:   St. Petersburg State Institute of Technology, Chesnokov Yurii G.
Published: May 2024

The work shows that the ratio of turbulent viscosity to kinematic viscosity and the Reynolds number calculated from the dynamic velocity weakly depends on the Reynolds number, but this dependence is not monotonic. Data from direct numerical modeling of turbulent flow in pipes known from the literature show that if, instead of the Reynolds number calculated from the dynamic velocity, we use the Reynolds number calculated from the average velocity over the cross section, the indicated dependence becomes monotonic and at large values of the Reynolds number the ratio of turbulent viscosity to kinematic viscosity and Reynolds number tends to a finite limit. Formulas are obtained for calculating the maximum value of turbulent viscosity and the cross-sectional average value depending on the Reynolds number.

Community Displacement and Language Shift (In Reference to the Khamyang Community of Assam)
Authors: - BISWAJIT DAS
Published: May 2024

Language extinction has become a global crisis at the present time. Linguists and sociologists across the world have shown concern about this matter. A report says that every fourteen days, a language vanishes. However, language extinction does not always mean that native speakers of the languages are dead. Language Shifting is another cause of language extinction. The root cause of language shift is mainly discussed from a social perspective. Language endangerment may result from external forces, such as military, economic, religious, cultural, or educational subjugation. Thus, negative attitudes towards one’s own language may be an internal cause of a community. Sociolinguists have found that various factors seem to correlate with language shifting and diminishing in size. Voluntary or forced migration to a location outside their traditional territory has been a major cause for a community to change their language. Generally, minority people who migrate to other places sooner or later shift to the new dominant language. The present paper is a study on a small minority group, named Khamyang, living in Upper Assam, to discuss how the displacement compelled them to shift their language.

Published: May 2024

У статті наведено важливість прийняття етичних та стійких практик у торгівлі та утриманні домашніх птахів. Негативний вплив торгівлі дикими птахами на біорізноманіття та благополуччя тварин виявляється у високому рівні смертності виловлених птахів, а також у зниженні популяцій диких видів через їх зазначене вилучення з природного середовища. Повне врахування потреб птахів у їхньому утриманні, включає в себе надання їм достатнього простору для руху, соціалізації та фізичної активності, а також забезпечення належної годівлі та мінімізацію ризиків захворювань. Реформи у законодавстві, спрямовані на заборону вилову птахів з дикої природи та встановлення стандартів утримання домашніх птахів, можуть бути кроком у напрямку забезпечення кращого добробуту та захисту для птахів. Крім того, необхідна підтримка та навчання власників щодо належного догляду за своїми птахами, щоб вони могли забезпечити оптимальні умови для своїх улюбленців. Враховуючи спостереження та рекомендації, можна зробити висновок, що важливо розробляти та впроваджувати стратегії, спрямовані на покращення умов утримання та захисту домашніх птахів, а також зменшення впливу торгівлі дикими птахами на дикі популяції.

Збільшення поголів'я кіз, підвищення їх продуктивності та обсягів виробництва продукції базується на вирішенні низки технічних, технологічних, організаційних та економічних питань. Сучасні проблеми розведення та розвитку кіз потребують поглибленого вивчення існуючих порід, породних груп та потенціалу вдосконалення і виведення нових типів продуктивних м'ясо-молочних ранньостиглих порід кіз, здатних більш ефективно використовувати кормові ресурси для виробництва м'яса та хутра, а також конкурувати з іншими інтенсивними галузями тваринництва. Ці питання включають, насамперед, оцінку відтворювальних і продуктивних якостей кіз, визначення ступеня впливу генетичних факторів на розвиток продуктивних ознак, вивчення закономірностей успадкування ознак та їх взаємозв'язків, дослідження селекційних випробувань тварин з метою поліпшення бажаних ознак при чистопородному розведенні та схрещуванні.Протягом багатьох років в Україні розводили кіз для виробництва вовни. Внаслідок фінансово-економічної кризи виник розрив між ціною на продукцію козівництва (переважно м'ясо) та ресурсами, необхідними для її виробництва, а поголів'я кіз скоротилося приблизно у 8,3 рази.Підвищення конкурентоспроможності галузі козівництва в сучасних умовах зумовлене її м'ясною продуктивністю. Спеціалізація на виробництві м'яса молодняку кіз потребує порід з високою м'ясною продуктивністю. Цій вимозі повною мірою відповідають м'ясо-молочні та м'ясні породи з такими важливими біологічними характеристиками, як скоростиглість, плодючість, інтенсивний ріст і розвиток, конверсія на більш економічні кормові продукти та можливість використання тварин у господарських цілях на ранній стадії.В даній статті проведено дослідження: як впливає порода цапа на відтворювальну здатність козематок зааненської та альпійської порід.

Authors: HG Afifah Ayuni , Syafruddin Ilyas  , Olivia Avriyanti Hanafiah
Published: May 2024

Background: Dry socket or alveolar osteitis is a condition characterized by the breakdown of blood clots due to excessive fibrinolysis activity, which disrupts the wound healing process. Consumption of nutrition-rich foods such as snakehead fish (Channa striata) rich in albumin, omega-3 fatty acids, vitamins, minerals, and striatin may accelerate delayed wound healing. This study aimed to analyze the role of snakehead fish extract on the expression of TGF-β1 in the healing of dry socket wounds after tooth extraction in Wistar rats.
Methods: This study was an in vivo study with a posttest-only control group design. Forty-five Wistar rats were divided into five groups: snakehead fish extract groups with doses of 1/2, 1, 2, 4 times human dose, and a negative control. The lower left incisor teeth of the rats were extracted, then dry socket was induced with adrenaline using a paper point. On days 3, 7, and 14, TGF-β1 expression was assessed using immunohistochemical staining.
Results: This study showed significant difference in TGF-β1 expression on days 3, 7, and 14. TGF-β1 expression was higher in the treatment groups than the control (p<0.05).
Conclusion: Administration of snakehead fish extract increased TGF-β1 expression. These findings underline the complex interaction between snakehead fish extract and TGF-β1 expression.

Railway transport is the leader of the Russian transport market and one of the largest companies in the global transport sector. This powerful tool not only serves as a driving force for the development of many industries in the Russian Federation, but is also one of the criteria for assessing well-being and welfare of its citizens, which dictates the need for a detailed study of all aspects of the functioning of railway production. When considering the quality of the implementation of railway services, special attention must be paid to the internal quality system, namely, corporate culture, working conditions, quality of service, and a multi-level team management system. In modern rapidly changing socio-technological conditions of development of the transport industry, the efficiency and competitiveness of a railway transport specialist is determined not only by the quality of knowledge and skills in the structure of professional competencies, but also by a set of personal qualities that allow optimal ergonomic passage through the stages of socio-technological adaptation and further professionalization. A multifactorial analysis of “social competence” as a pedagogical category, from the standpoint of activity-based, personal, subjective, axiological, competence-based approaches, the study of regulatory documentation and conditions for the implementation of professional activities in transport, made it possible to determine the essence and structure of the social competence of railway specialists as an integrative quality of personality, the structure of which can be represented by a set of motivational, value, emotional, and communicative components. The choice of indicators (social initiative and activity, the ability to transmit generally accepted and intra-industry social values, empathy, tolerance, self-esteem, ability for effective communication, social mobility) in the structure of social competence is substantiated and the levels of their formation are determined. Situational and functional approaches to identifying the content of the main stages of socialization in the professional training of railway transport specialists made it possible to specify the psychological and pedagogical conditions for the targeted formation of indicators of social competence: incessancy and continuity in the development of a block of socially oriented disciplines; practice-oriented educational process; active learning methods; design technologies; formation of an active subject position of students

Published: May 2024

High wind performance systems are influenced by many factors such as site wind resources and configuration, technical wind turbine features and many financial conditions. Scenario planning and modelling activities often focus on restricted parameters and numbers to justify wind power plant performance. To better understand possible pathways to scaling up the distributed wind market in Albania, a deep and multidimensional calculations based on Monte Carlo analysis, using RETScreen and wind JEDI model, to assess socio-economic impact as a function of turbine output power, operating and maintenance cost and many other financial inputs by testing different WT (i.e., VESTAS, GAMESA, W2E and NORDEX) with rated power from 3.45 MW up to 4.5MW applied on LCOE, NPV, SPP, equity payback, B-C, after-tax IRR on equity and effects of GHG credits extended at a sensitivity range of ±35% is scientifically performed. From the simulation results LCOE reaches a minimal value of €43.48/MWh, if the debt rate is 99 % and a debt interest rate of 5.0%, a TotCapEx of €828/MW (-35 % less expenditures) indexed as the best scenario. For the base case scenario LCOE results €62.79/MWh, when applying a debt rate of 80% and a TotCapEx of (€1274/MW), while in the worst-case scenario LCOE impart a maximal value of €87.63/MWh if a TotCapEx of €1720/MW (+35 % more expenditures) and a share of 52 % debt rate is applied. Local annual economic impact (m€) during construction period and operating period evaluated in the wind JEDI model result around m€ 89.92 and m€ 23.54, respectively. As a conclusion, wind power plants (WPP), installed in low wind zones (Albania and many other EU countries) would be of interest if an electricity export rate of 110€/MWh, and a GHG credit rate of €50/tCO2 were accepted.
Bumpy ride ahead: Anticipated effort as emotional evidence?
Authors: Oz-Cohen Elad , Berkovich Rotem , Meiran Nachshon
Published: May 2024

Conscious reportable (un)pleasantness feelings were shown to be successfully described by a process in which evidence favoring pleasant and unpleasant feelings accumulates until one response wins the race. This approach is challenged by (a) insufficient specification of “evidence,” and (b) incomplete verification that participants report their truly experienced (un)pleasant feelings and not what they expect to feel. In each trial in this preregistered experiment, the (un)pleasant feeling reports regarding emotion evoking pictures was embedded in a period when participants expected a low-effort task (feature visual search) or a high-effort task (feature-conjunction search). Fitting the Linear Ballistic Accumulator model to the feeling report data shows that anticipated effort was associated with a higher rate of unpleasant evidence accumulation, but only when the emotion evoking pictures were normatively unpleasant and not when they were normatively pleasant. These results suggest that anticipated effort may be one source of “evidence,” but only given a certain interpretation of the findings, and that genuinely felt emotions contribute to the emotion reports, assuming that participants intended to react to the pictures, as instructed, and not to the anticipated effort.

This study delves into the experiences of EFL pre-service teachers engaging in a digital storytelling project to practice their speaking, with a focus on exploring significant learning outcomes through Fink’s 2003 theory. This qualitative case study utilized semi-structured interviews and project reports as instruments, collecting data from five EFL pre-service teachers at Mulawarman University Samarinda through purposeful sampling. Thematic analysis was employed to analyze the data. Four major themes emerged from the data's thematic analysis, which encompassed the experiences of the participants: participation in the process of creating digital stories, focused speaking exercises, integration of other language abilities, and self-evaluation techniques. These themes also brought attention to the participants' learnings about digital storytelling for public speaking, the difficulties they faced, and the spectrum of emotions they went through. Furthermore, the significant learning outcomes they experienced were marked by an improvement in speaking skills and the establishment of speaking habits. Participants also gained insight into the relationship between activities such as writing scripts, recording, and reading for text reviews, all of which contributed to practicing their speaking. This project fosters self-awareness, enhances understanding of others, and instils an interest in undertaking similar projects in the future. Demonstrated ongoing learning highlights the impact of digital storytelling beyond technical skills, serving as a valuable tool for speaking practice.

Published: May 2024

Aim: The regulation of blood glucose levels is controlled by insulin, which is produced by the pancreatic beta system. Inadequate synthesis of beta insulin, results in elevated glucose levels, a condition known as diabetes, which can lead to various chronic health issues. In recent times, the diagnosis of diabetes, particularly type 1, has shifted towards the direct measurement of insulin levels. To facilitate this, an immunosensor was created to enable rapid and sensitive examination of insulin levels, with the goal of improving the quality for life for diabetic patients.
Material and Method: For this purpose, an insulin tracer protein based biosensor was designed for the determination of insulin at all solutions. For determination of insulin, electrobiochemical analyses were performed. Optimisation and characterisation studies were performed using differential pulse voltammetry. The performance of bioelectrochemical system was analysed by Receiver Operating Characteristic method.
Results: The insulin biosensor cyclic woltammogram was obtained between -0,1 and 0,6 V potantial. At 0,45 V was found as the anodic peak side for determination the insulin. Optimisation and characterisation studies performed at 0,45 V with differential pulse voltammetry.
Conclusion: The study successfully identified stable and easy-to-use insulin concentrations, indicating the potential of the newly developed immunosensor for applications in clinical biochemistry laboratories.
