In vitro analysis of the inhibitory activity of extracts, fractions and secondary metabolites of plants of the genus Silene (Caryophylaceae) and Serratula cupuliformis (Asteraceae) to the «entry» of herpes simplex type 2 (HSV‐2) into sensitive cells of the Vero line.

Ethanol extracts and butanol fractions of Silene spp. and Serratula cupuliformis were prepared. The flavonoid shaftoside and the ecdysteroid 20‐hydroxyecdysone from Lychnis chalcedonica were isolated. For analysis of biologically active substances (BAS) the HPLC method was used. The samples were dissolved in distilled water or DMSO. The laboratory strain MS HSV‐2 was grown on Vero cell culture. In vitro analysis of the inhibitory activity of the herbal preparations on «entry» of HSV‐2 was performed in Vero cell culture by direct inactivation (neutralisation) of virions with 103 PFU /ml.

Effective concentrations (EC50) have been identified in the range of 50 % from 2.12±0.47 to 180.99±49.24 μg/ml when preparations were dissolved in water and from 1.99±0.44 to 57.42±14.74 μg/ml when they were dissolved in DMSO. Such results for some samples is comparable to the EC50 of comparison preparations (dry ethanol extracts of spice of cloves, chaga and licorice root). The results obtained suggest the presence of BAS in the herbal preparations studied that act destructively on HSV‐2 virions and affect one of the main stages of its «life» cycle – the «entry» of the virus into sensitive cells.

To research the molecular genetic characteristics of the HCV population circulating among HIV‐infected residents of the Krasnoyarsk Territory, including analysis of resistance‐associated mutations to NS5A inhibitors. Total RNA was isolated from 94 blood plasma samples from HIV/HCVinfected residents of the region and the nucleotide sequences of the Core/E1 gene and NS5A gene regions were obtained and deciphered, which were used for genotyping and searching for resistance mutations.

In the HCV samples studied, the circulation of five virus subtypes was recorded: 1b (47,9 %), 3a (37,2 %), 1a (10,6 %), 2a (3,2 %) and 2k (1,1 %). Phylogenetic analysis of HCVs revealed partial clustering within subtypes 1a and 3a on a territorial basis. HCV subtypes 1b, 2a and 2k were grouped with other HCVs previously isolated in Russia, Armenia and Kyrgyzstan. Among the HCVs studied, no clusters were found that were common to HIV‐infected individuals with the same route of infection. Among patients who had no experience of taking DAAs, HCV resistance mutations in the NS5A region were found in 42,3 % of cases for those infected with subtype 3a virus and in 75,6 % of cases for those infected with HCV subtype 1b.

The analysis of the diversity and occurrence of mutations of HCV drug resistance to direct antiviral drugs is extremely important for the development of tactics for effective treatment of CHC. The high prevalence of polymorphic mutations that affect sensitivity to DAAs indicates the relevance of introducing HCV resistance analysis into clinical practice.
The first find of the pond bat Myotis dasycneme (Boie, 1825) in Stavropol Territory and western Caucasus, Russia

Published: April 2024

The aim of the work was to describe the discovery of a pond bat Myotis dasycneme (Boie, 1825) in the vicinity of Zheleznovodsk, Stavropol Territory, Russia in August 2023.

We examined the Letnei Merzloti Cave, an artificial tunnel about 400 metres long with small dead‐end caverns. The pond bat was found in a small dead‐end cavern. This is the first find of this species in the Stavropol region and the third find in the Caucasus.

The first finds of the pond bat were made in the Western Caucasus in 1999 and 2003. This find provides more data about a small population of pond bats in the Caucasus. It is noteworthy that this species of bat (M. dasycneme), together with M. daubentonii, are the only known natural wild hosts of the Europian bat lissavirus virus type 2 in Europe. Given the fact that bats are considered natural hosts of all types of coronaviruses, and that the pond bat previously evidenced the circulation of both alpha and beta coronaviruses in the European population (Germany, the Netherlands), we must be aware of the potential of this species as a reservoir of pathogenic zoonotic coronaviruses.

Authors:   Southern Federal University, Nguyen Buu Hoang , Tsybulin Vyacheslav ,   Southern Federal University
Published: April 2024

The aim of this work is to develop a compact finite-difference approach for modeling the dynamics of predator and prey based on reaction-diffusion-advection equations with variable coefficients. Methods. To discretize a spatially inhomogeneous problem with nonlinear terms of taxis and local interaction, the balance method is used. Species densities are determined on the main grid whereas fluxes are computed at the nodes of the staggered grid. Integration over time is carried out using the high-order Runge-Kutta method. Results. For the case of one-dimensional annular interval, the finite-difference scheme on the three-point stencil has been constructed that makes it possible to increase the order of accuracy compared to the standard second-order approximation scheme. The results of computational experiment are presented and comparison of schemes for stationary and non-stationary solutions is carried out. We conduct the calculation of accuracy order basing on the Aitken process for sequences of spatial grids. The calculated values of the effective order accuracy for the proposed scheme were greater than the standard two: for the diffusion problem, values of at least four were obtained. Decrease was obtained when directional migration was taken into account. This conclusion was also confirmed for non-stationary oscillatory regimes. Conclusion. The results demonstrate the effectiveness of the derived scheme for dynamics of predator and prey system in a heterogeneous environment.

Published: April 2024

The influence of various phytomeliorants on the content and reserves of humus, the content of microelements, microflora and optical parameters of agrogenic soils of Primorye were studied. Sowing legumes with annual and perennial crops activates the processes of humus accumulation, increases the biogenicity and catalase activity of soils. The most positive effect on the increase in humus content, catalase activity and soil biogenicity in the experiment with annual grasses was noted for the “oats + vetch” guide. Humus reserves reached the level of average values. In the variant of the experiment, “oats + beans”, the amount of humus and its reserves in the 20 cm layer decreased due to waterlogging of the soil and the weakening of the processes of transformation of organic matter by microflora. In the experiment with perennial grasses, the highest humus content and indicators of catalase activity were recorded for the “timothy grass + alfalfa” variant, the “timothy grass + clover + alfalfa” variant differed in the largest reserves of humus and biogenicity. Due to the decrease in the density of soil composition, in the variant with the sowing of the grass mixture of timothy “grass + alfalfa”, the humus reserves in the 20 cm layer decreased slightly (to 108.6 t/ha). A close inverse correlation was established between the addition of humus and the integral reflection. When considering with regional clarke values, an imbalance in the microelement composition of the studied soil samples of the upper horizon was revealed.
Repensando o feminismo com Françoise Vergès - perspectivas do Sul Global
Authors: Da Silva Alana Pereira
Published: April 2024

Para pensar em um feminismo descolonizador, Françoise Vergès se aproxima das produções intelectuais do Sul Global e realiza um diálogo com intelectuais africanas, latino-americanas e asiáticas. O feminismo decolonial concentra esforços em analisar os problemas sociais ocasionados pela colonialidade. Desse modo, Françoise Vergès ressalta a importância de um feminismo militante que traga à tona as estruturas racistas do Estado através da luta coletiva. Nesse sentido, a luta deve continuar sendo sobre equidade de gênero, mas enquanto este movimento não reconhecer o racismo de uma luta que se cristaliza apenas no gênero, mulheres racializadas permanecerão em situação de vulnerabilidade, o que denmostra que o feminismo, nesses moldes, precisa ser repensado.

Published: April 2024

El antecedente de lamentables prácticas de investigación en seres humanos registrado hace más de 70 años fue el origen de los acuerdos y regulaciones internacionales actuales en esta materia. En México, la legislación sobre investigación en salud se adhiere al marco regulatorio y principios internacionales de ética en investigación en seres humanos. Dicha legislación reconoce los beneficios científicos y sociales de la investigación en salud, antepone los derechos de los sujetos de investigación al interés de progreso científico y se inscribe en un marco regulatorio integrado por leyes y reglamentos aprobados por el Congreso de los Estados Unidos Mexicanos, así como normas y guías expedidas por órganos desconcentrados federales, técnica y operativamente autónomos. En este trabajo, se proporciona una visión global del marco regulatorio de orden superior vigente en México, así como de las atribuciones generales de las distintas dependencias federales en materia de investigación en salud, con el objetivo de facilitar la incorporación inicial de sus distintos elementos a la estructura orgánica de los establecimientos médicos, centros de investigación y universidades mexicanas que aún no cuentan con una organización interna basada en la norma o que necesitan actualizarla.
Miejsca, w których uprawia się myślenie. Działalność czasopism kulturalnych w Polsce po 1989 roku
Authors: Nolbrzak Renata
Published: April 2024

Po 1989 roku, wraz z otwarciem granic, pojawieniem się wolnego rynku oraz zniknięciem w Polsce cenzury, blokującej niezależną twórczość nastąpiło ożywienie w sferze kultury. Ważnymi animatorami życia kulturalnego, szczególnie w obrębie literatury stały się środowiska związane z pismami kulturalnymi. W latach 90. nastąpił ogromny wysyp nowo powstających czasopism. Ich znaczenia nie można przecenić. To właśnie czasopisma wypromowały wielu wybitnych autorów oraz były inicjatorami najciekawszych zjawisk literackich w Polsce po 1989 roku. Wiele z tych pism ukazuje się regularnie do dziś, wiele tytułów jednak upadło, często z ekonomicznych względów. W ciągu minionych dwudziestu kilku lat pisma kulturalne, wydawane najczęściej przez stowarzyszenia i fundacje, były finansowane z różnych źródeł, głównie dotacji samorządowych i ministerialnych. W roku 2011 Ministerstwo Kultury i Dziedzictwa Narodowego przyznało dotację na działalność czasopism kulturalnych tylko 47 redakcjom, a zasady rozdysponowywania środków są niejasne i w niewielkim stopniu uwzględniają wartość artystyczną pism.

The Power of Diversity: Managing Inclusion for Global Sustainability
Authors: Casanova Mederos Myrtha Beatriz , Barguñó Javier
Published: April 2024

Diversity is the nature of humanity, of men and women whose profiles are highly different. The same applies to the structure, behavior and results of how they interrelate, the institutions they create, and the governance tools they use. This evidence is an axiom of everything that concerns humanity. Globalization has brought together people and their differences to act in a unique, dynamically diverse space in constant transformation. Including these diversities is key to the sustained development of organizations, regions and nations. In the nineteen fifties and sixties of the ninetieth century, the scientific community established that Diversity would be the distinguishing factor of the twenty-first century, with Albermathy and Utterback in the forefront, among other researchers. The science of Diversity emerged. And so, the development of intelligence would be critical to understand and manage the behavior of men and women as they move forward in search of a sustainable future. In the eighties, the scientific community —Johnston and Packer (1987), among others— not only further researched the concept of Diversity but also established that it is responsible for the generation of conflicts at global, local and group levels in this century. Later, in the nineties, further analyzing the consequences, researchers such as Cox and Blake identified Diversity as the main generator of innovation. Diversity, therefore, is the key factor for organizations to develop inclusive policies that enhance the value of difference with the aim of turning it into an advantage and not as a menace to people and the institutions they govern.
A Critical Review of the Plight of Teenage Pregnant Girls Displaced by the COVID-19 Pandemic in Namibian Schools
Authors: Hako Anna Niitembu , Shikongo Prisca Tautiko , Shanyanana-Amaambo Rachel N.
Published: April 2024

The phenomenon of teenage pregnancy has become a thorn in the flesh for many countries, including Namibia as many learners become pregnant while schooling. This study gives an exploratory analysis on the increased number of girls who were impregnated during lockdown. Pregnancies among learners threaten not only their human rights, but their health and social welfare, as well as the health and welfare of the children born to them. These young females often terminate their education, and this has implications for girls becoming uneducated, thereby hindering their ability to contribute to the socio-economic development of the country, as opposed to their male counterparts. This practice may lead to a perpetual cycle of the culture of poverty in which their children may further go on to become teenage parents. Using a critical review of secondary data, this study examined the higher rate of teen pregnancy among girls in Namibian schools during the COVID-19 pandemic. Numerous sources, including academic databases, scholarly journals, books, laws, policies, programs, newspaper stories, school reports, and guidelines for life skills education, are included in the literature review. The gathered data was subjected to thematic analysis in order to provide light on the difficulties that girls encountered throughout the pandemic. Therefore, this critical review paper focuses on four main areas: it presents the plight of teenage pregnancy displayed by COVID-19 in Namibia; depicts the ideas of learner pregnancy policy and life skills education guidelines; reveals factors influencing teenage pregnancy in schools in Namibia; and unpacks the implications of learners’ teenage pregnancy (pertaining to human rights, health, socio-economic, psychological/mental health) on education, women and girls’ empowerment agenda, and socio-economic development. The article concludes by unveiling strategies to mitigate the scourge (the fresh ways of dealing) with the plight of teenage pregnancy in this transforming society and point out some areas for further studies. Although the answers provided by theoretical analysis are not always definitive in nature, they might provide some insights into future phenomena.
Calculation of cooling time of above-ground water pipeline with heat insulation under conditions of negative temperatures
Authors: Lapshin Vladimir
Published: April 2024

Objective: transport infrastructure facilities include a variety of water supply systems. In the event of an emergency, after stopping the movement of water in the pipeline, it is cooled first, and then there is a risk of freezing and destruction of water pipelines. This work is devoted to the calculation of the cooling time of water in the above-ground water conduit with thermal insulation from the specified temperature value in the initial state to the freezing temperature. Methods: when building a mathematical model of the water cooling process, an approach is used based on averaging the equations of hydrodynamics by the volume of water in the pipeline and averaging the equations of thermal conductivity in the wall of the pipeline and in the layer of the heat insulator by the polar angle. To obtain a quasi-stationary form of equations, a comparative analysis of the rates of thermal processes in different layers of the water conduit is used. Results: a new mathematical model for cooling the water pipeline is formulated — a model of average temperatures. The applicability of the quasi-stationary form of the equations of the model is justified and its analytical solution is found. Explicit formulas are obtained for cooling time of water conduit as a function of its parameters. Cooling time was calculated in a wide range of parameters. The results of model calculations are compared with calculations according to traditional semi-empirical formulas. Practical importance: the formulas obtained in the work can be used to estimate the cooling time of water in an above-ground water pipeline with heat insulation to the freezing temperature in the case when the ambient temperature drops to negative values.

A set of services has been revised and proposed based on the volume of services consumed and actual customer requests. Methods: the work uses methods of empirical and experimental-theoretical level: observation, questioning, comparison, data analysis, etc. Results: practical examples and recommendations of services for railway stations are given, due to the adaptive transition to the separation of services in customer service (“single window”). Practical significance: the paper defines a typical set of services at railway stations, with a subsequent assessment of the possibility of considering them as a corporate asset.
On the dependence of soil freezing on humidity
Authors: Shtykov Valeriy , Ponomarev Andrey , Yanko Yuri
Published: April 2024

Purpose: the temperatures at which soils begin to freeze during the onset of frost are of interest primarily to agricultural workers and construction workers. It was previously established that many factors influence soil freezing. However, not enough research has been carried out on the influence of individual factors on the freezing process. The article examines the influence of soil moisture on their supercooling and freezing temperatures. Methods: the studies were carried out in a microrefrigerator with three freezing modes. Results: it was found that with constant shaking, the supercooling temperature increased, but the freezing temperature did not change. Graphic dependences of the temperatures of supercooling and freezing of soils on the initial humidity were obtained. The degree of soil compaction did not affect these temperatures. The temperatures of supercooling and freezing of soils depend to a greater extent on the dispersion of soils than on the content of organic substances in them. Practical significance: the results of the work are important for construction as they expand the understanding of the features of the mechanism of soil freezing.

Authors: Grigorenko Pavel , Mel'nichenko Oleg , Portnoy Aleksandr , Samoylova Anastasiya
Published: April 2024

Objective: to develop a way to improve the quality of electricity on the current collector of an alternating current electric locomotive when it is operating in the first control zone with transistor traction converters. Methods: the electromagnetic processes on the current collector and in the power circuit of an alternating current electric locomotive with thyristor and transistor traction converters are analyzed, their comparison is made according to the criterion of distortion of the quality of electricity on the current collector. The electromagnetic processes on the current collector and in the power circuit of an alternating current electric locomotive with transistor traction converters operating according to the proposed method — spaced control are analyzed. Results: the causes of voltage and current fluctuations on the current collector of an alternating current electric locomotive with a transistor traction converter in the first rectified voltage regulation zone have been identified. A method of spaced control of transistor traction converters has been developed, which allows reducing the total coefficient of harmonic components of current and voltage on the current collector of an alternating current electric locomotive. Practical importance: the developed method of spaced control can be used on AC electric locomotives after their conversion to transistor traction converters, as well as in the design of new electric locomotives.

Authors: Chestno Arseniy
Published: April 2024

Objective: to develop and apply software for automatic finding of discrepancies in automated meteorological stations in order to identify dubious and unreliable data without direct manual control in Fortran using PostgreSQL programming language queries. Write a program block for processing data from the archive of the database of meteorological stations of the unified network. Having provided a connection, with the help of requests, to ensure the receipt of data of the averaged values of ten-minute meteorological reports according to a special processing technique. Create a subroutine for solving the equation by the least squares matrix method, compare it to check the results with the linear regression method in a third-party application. Ensure proper recording of data before sending them to the database, prepare the necessary table for correct demonstration of data and user convenience in their use. Formulate correct queries to send the results of finding the discrepancy to the database. Formulate queries to create the necessary table, formulate queries and identify conditions for the implementation of the program for its more “flexible”functioning, that is, the ability to process data and find a discrepancy in the case of non-daily operation of the program. Methods: the methodology is similar to the principles of recommendations for the analysis of the results of spatial monitoring of regime meteorological information of the Main Geophysical Observatory named after Voeikova A. I. Methods include the translation of coordinates into a Cartesian system and the implementation of the solution of equation systems by the least squares method. Results: a program has been created that can work without the participation of an operator, performing automatic startup, data processing and data recording for further storage. Practical importance: the program allows you to receive data quickly due to the fast processing speed without errors caused by the human factor.

A brief description, applications, advantages and limitations of extraction-gravimetric, butyrometric, refractometric, chromatographic, ultrasonic, turbidimetric, NMR, and IR spectroscopic methods for measuring fat content are presented. Standardized measurement techniques regulated in national (GOST R), interstate (GOST), and international (ISO, AOAC) standards are analyzed, taking into account the method used, areas of application, and metrological characteristics. An overview of testing equipment and measuring instruments for implementing various methods for determining fat content is given. Particular attention is paid to the consideration of certified express analyzers of food products and food raw materials. A list of certified reference materials for the composition of dairy and grain-milk products, fish and meat products, oilseeds and their processed products, compound feed, egg powder and wheat crackers with a certified value of the mass fraction of fat is provided, their metrological characteristics and certification methods are listed. Based on the results of the study, the main features and problems of ensuring the uniformity of measurements of fat content in food products and food raw materials were formulated, and perspective directions for the development of metrological support were identified.
On the Additive and Subtractive Representation of Even Numbers from Primes
Authors: Shehu Ali , Uka Jetmira
Published: April 2024

We demonstrate a new quantitative method to the sieve of Eratosthenes, which is an alternative to the sieve of Legendre. In this method, every element of a given set is sifted out once only; and therefore, this method is free of the Mobius function and of the parity barrier. Using this method, we prove that every sufficiently large even number is the sum of two primes, and that every even number is the difference of two primes in infinitely many ways.
A 'Turing Test' for Self-Awareness
Authors: Witkowski Cameron
Published: April 2024

In this paper, I propose a test for machine self-awareness inspired by the Turing test. While my test is plain and simple, it offers a much-needed alternative to ungrounded speculation while still capturing the essence of self-awareness. I discuss how to apply the test to Large Language Models and conduct experiments on GPT-3.5 that suggest it is not self-aware. I discuss the implications of machine self-awareness and relate it to questions about meaning and understanding. Finally, I present some next steps for studying self-awareness in machines.

Abstract. The national curriculum of learning takes place through the Scientific Approach, students are guided to be able to find learning material by themselves. Not all students can be easily active in learning, because they are afraid to ask questions, lazy even some do not understand so learning is increasingly confusing. Learning with the habits of students want to explain the teacher, making students less active in the learning process and the results obtained are not optimal. Chemistry is often considered to be an elusive lesson that causes student
dislike. Pleasant learning methods are needed so as to create joyful nuanced learning situations that make students absorbed, comfortable and excited. The learning method chosen in this study was the KIMLA learning method, namely the method of discussion using songs as a medium in learning Chemistry. With the KIMLA method, it is expected that there will be an increase in the activeness and learning achievement of students in the periodic Chemistry System Learning subject elements. This research is a Classroom Action Research conducted at
SMA 1 Ceper Klaten, in the odd semester of the 2018/2019 academic year in September 2018 - October 2019, the target in this study was the tenth grade students of MIPA 1 with 28 students consisting of 12 sons and 16 daughters. Data obtained through observation are direct observations when taking student learning activities data, and assessment sheets are continued by analysis of the average pre-action test scores, cycle 1 and cycle II. The criteria for the success of giving an action are if students get a minimum score of 67 KKM, with the percentage of learning completeness 75% of 28 students, while the success criteria for learning
activeness are 80%. Based on the results of the research and discussion it was concluded that there was an increase in the activeness of students to 96.4% and 100% learning outcomes completed with an average of 79.

Authors: Saputro Alfisyah Ajrin
Published: April 2024

Fokus penelitian ini untuk menguraikan pesan-pesan yang terdapat dalam relief-relief Candi Sukuh yang dianggap masih tabu. Studi ini dilaksanakan karena Candi Sukuh dapat menjadi bukti bahwa jauh sebelum adanya gerakan feminisme, masyarakat yang menganut agama Hindu-Buddha pada masa lampau sudah mengakui perbedaan antara laki-laki dan perempuan. Perbedaan tersebut menjadi suatu konstruksi sosial yang dipahami dalam hubungan kompromi laki-laki dan perempuan. Metode yang digunakan dalam penelitian ini adalah studi lapangan dan deskriptif-interpretatif, dan data dianalisis dengan pendekatan multidesain. Teori yang digunakan adalah Teori Ikonografi untuk menganalisis pesan dari relief-relief Candi Sukuh, sedangkan teori feminisme diterapkan dengan pendekatan gender, tubuh, dan seks. Hasil penelitian menunjukkan adanya pesan feminisme pada relief linggā dan yoni. Kesimpulannya pesan gender yang disajikan di relief linggā dan yoni pada Candi Sukuh berupa penolakan perempuan terhadap pengobjekan tubuhnya oleh kaum laki-laki, yang dianggap mempunyai otoritas terhadap tubuh perempuan.
