Introduction. Calculation studies have shown that due to the long-term operation of hydraulic structures of the sluice, opening of horizontal and vertical construction joints, as well as corrosion of reinforcement at the rear edge of the reinforced concrete wall of the sluice in the areas of horizontal construction joints, the bearing capacity of the structure as a whole is reduced. In this regard, it is necessary to strengthen the structure, the methodology of which is given in this study. Materials and methods. The analysis of scientific and technical documentation has been made, instrumental examination of the state of structures has been carried out, a spatial mathematical model has been developed on the basis of the finite-element method. Multivariant calculated researches of the actual stressed-strained state (SSS) of structures have been made. Calculation studies of the SSS structures were performed taking into account the reinforcement of prestressed basalt composite reinforcement (BCR). Results. Visual and instrumental inspection showed a presence of cracking on the front face of the reinforced concrete wall of the sluice chamber. Modeling of the actual state of SSS structures is performed, according to the results of calculations, a scheme for strengthening structures of prestressed BCR is proposed and justified. Conclusions. As a result of the calculated studies of the deflected stresses, the occurrence of cracks and opening of horizontal and vertical construction joints in the reinforced concrete structure of the sluice chamber wall was confirmed. At the same time, taking into account corrosion of reinforcement at the rear edge of the sluice’s reinforced concrete wall in the areas of horizontal construction joints, stresses in it reach the design resistance of the reinforcement of class A-II. In order to ensure further safe operation of the structures, the scheme of strengthening the structures with prestressed BCR has been proposed and substantiated.

Published: February 2023

Introduction. Problems of waste gas heat recovery are relevant in the course production activities. Secondary thermal ener­gy resources are the most widely spread type of energy waste. Efficient recovery of waste heat will reduce energy costs. The building of a cafeteria, that has a water-heating waste heat boiler (WHB) represents a widely spread type of industrial buildings in eastern countries, where hot water and heating can be provided by using heat waste recovered from groups of tandoor furnaces. The purpose of the research is to study unsteady convective flows of heat passing through the pipe of a tandoor heat exchanger and to develop a simple design of a small-sized, easy to manufacture, economical and safe model of a water heating device for the needs of the national economy. Materials and methods. The research is based on a comprehensive methodology employed to study, analyze and gene­ralize thermophysical processes based on the study of convective unsteady heat flows in heat exchanger pipes of tandoor furnaces. Results. The research result represents higher thermal efficiency of the WHB installed in the building of a cafeteria due to the heating, accumulation and heat transfer by vertical finned steel heat-exchanger pipes in the cylindrical boiler in the course of convective heating by the outlet gas used as the heat carrier without returning heat to the water heating boiler. Conclusions. The cafeteria building has scientifically and practically grounded design of a WHB tandoor group, which is a vertical cylindrical tank filled with water, in which vertical outlet heat exchange pipes are placed. Heat, emitted during the operation of tandoors, is used to bake flatbreads and bread by burning wood, coal, natural gas or electric heaters. This heat heats boiler sections to supply hot water to consumers and heat the building premises. The method of finned pipes extends the field of application of the device, increasing the coefficient of heat capacity and heat exchange, as well as the capacity of equipment.

Published: February 2023

Introduction. The purpose of the research is to establish the criterion for assessing the pipeline operation efficiency and verify the accuracy of hydraulic design of metal pipes that have internal deposits. Materials and methods. The authors provide calculated dependences to determine the values of the characteristics of the hydraulic potential of metal pipes having internal deposits. A specific case is employed to compare the characteristics of new pipes and pipes having different thicknesses of the layer of internal deposits. The percent discrepancy between pipe characteristics is provided. Results. The authors recommend evaluating the accuracy of the hydraulic design of water supply and sewerage networks having internal deposits in reliance on the value of the operation efficiency coefficient for water supply or sewerage networks. The authors offer a formula derived to determine the value of the efficiency coefficient for the operation of water supply and sewerage networks having internal deposits on inside walls of a pipe. The authors suggest systematizing the hydraulic design of metal water supply and sewerage networks that are made of metal and have deposits on the inside of pipe walls by taking into account the thickness of the layer of internal deposits, characterized by the value of the network operation efficiency coefficient. Conclusions. Systematization of hydraulic design of water supply and sewerage networks that are made of metal and have deposits on the inside of pipe walls allows for the acceptable accuracy of its hydraulic design that takes account of the actual value of the coefficient of efficiency of pipeline operation Kef, taking into account the value of actual thickness of deposit layer σact. In other words, systematization of hydraulic design of water supply and sewerage networks, having deposits on the inside surface of metal pipes, is based on the value of their efficiency coefficient Kef, that takes into account the actual hydraulic potential of pipes (pipelines) depending on the layer of internal deposits σact.

Authors:   Moscow State University of Civil Engineering (National Research University) (MGSU), Tusnina Olga A. , Postarnak Mikhail V.
Published: February 2023

Introduction. Large-span structures are designed as entertainment and mass-use buildings, sports facilities, etc. A steel arched structure can be used as a covering for large-span structures. The issue of the rational design of large-span steel arches, as well as the proper choice of the structural design and the analysis of its bearing capacity is relevant. Materials and methods. The covering of a tennis sports facility with the span of 108 m, that represents a double-hinged steel arch without tightening, arches with prestressed tightening and several lattice options are considered. The cross-section of structural elements was selected; the effect of prestressing on forces and displacements in the arch, as well as the amount of metal per structure were analyzed. The general stability of these arched structures was analyzed. Calculations were performed in the geometrically nonlinear formulation using the LIRA-SAPR software package. Results. It is determined that the weight of the arch, including the tightening and the lattice is smaller than the weight of the arch without the tightening. The amount of metal, used to make columns, can be reduced to simplify structural units due to the absence of gusset transfer from the arch with tightening to columns. The required prestressing value is set for the tightening to ensure the required rigidity of the arch. Several methods were used to determine the critical load at which the arch loses its stability in its plane: the analytical method, geometrically nonlinear calculation results, and the Stability mode implemented in LIRA-SAPR software package were employed. The critical load turned out to be higher for the arch with tightening. Conclusions. Following the above computations, a decision was made to use a double-hinged arch with prestressed tightening and a lattice as the covering of the sports facility. The values of the critical load that triggers the arch stability loss, obtained using the geometrical nonlinear finite-element analysis and the Stability mode, were quite close. Application of the analytical method resulted in an overestimated value of the critical load, which prevents it from being recommended for use.

El disposicionalismo nomológico y sus problemas: redundancia, experimentalismo y modalidad nómica
Authors: Soto Cristian
Published: February 2023

El disposicionalismo nomológico ha ocupado un lugar central en el desarrollo de la metafísica nomológica contemporánea, sosteniendo que las leyes de la naturaleza derivan de una ontología de propiedades disposicionales. Este enfrenta, no obstante, varios desafíos, algunos de los cuales conviene revisitar considerando que no han sido suficientemente destacados en la literatura. Entre otras cosas, el disposicionalismo condena a las leyes a redundancia ontológica; su reconstrucción de las propiedades no se condice fácilmente con el experimentalismo; introduce una concepción de modalidad metafísica que transita entre modalidad lógica (de dicto) y modalidad física (de re); y asume supuestos meta-metafísicos fundamentalistas. No nos interesa desmantelar el disposicionalismo nomológico –por el contrario, creemos que es una teoría valiosa–, sino identificar aquellos puntos en los que conviene considerar estrategias diferentes en una teoría de leyes.
Las neuronas espejo. Un caso de estudio de la relación neurociencia-filosofía
Authors: Pérez Diana I.
Published: February 2023

El descubrimiento del sistema de neuronas espejo, que acaeció hace 25 años, fue considerado por algunos autores como prueba definitiva de la superioridad de una teoría filosófica (la Teoría de la Simulación) por sobre otra (la Teoría de la Teoría). Sin embargo, esta pretensión de haber encontrado una respuesta definitiva al problema filosófico de la comprensión de las otras mentes a partir de datos neurocientíficos dista mucho de ser aceptable. En este trabajo mostraré que existe una multiplicidad de interpretaciones posibles relativas al rol de las neuronas espejo, y que una de las más plausibles parece congruente con la perspectiva de segunda persona (Pérez y Gomila 2021). La conclusión que busco extraer de este caso de estudio es que no hay caminos directos desde la neurociencia a la solución de (al menos algunos) problemas filosóficos.

Published: February 2023

The mosque is a center of worship for Muslims. Besides a place to pray, researchhas shown that the role of the mosque is not merely in spiritual concern. Mosques also have the role ofeducation, social and economic development. However, the relationship between the role of the mosque and the space use is yet unknown. The activity that creates space use should be analyzed to see whether created space meets the needs or not. This research aims to explore the space use of Syaikhona Kholil mosques in Bangkalan Madura. It has a unique layout with the tomb of the Indonesian ulama inside. Thus, the mosque is always crowded as a pilgrimage destination. The existence of this religious activity eventually led to economic activity to support the needs of the pilgrims, both religious needs and daily needs. Based on a qualitative approach, the primary data was collected through field observation, mapping of economic activities surrounding the mosque, and interviews. The result of the research shows that the activity of social and economic determined thespace used at the Syaikhona Kholil mosque. The economic space that are supporting the enlivenment of the mosque is not only shophouses, kiosks, and paddlers but also a large parking area. The tomb of KH Syaikhona Kholil affects the development of economic activities in the vicinity, changes the space usedaround it, and improves the lives of communities.

Análisis del escaso relevo generacional desde los modelos de desarrollo rural en Colombia
Authors: Rodríguez Espinosa Uriel , Correa Perdomo Andrea Victoria
Published: February 2023

Contextualización: el escaso relevo generacional en el ámbito productivo rural es una problemática en constante crecimiento a nivel global, este fenómeno afecta, principalmente, la agricultura a pequeña escala.

Vacío de conocimiento: los modelos de desarrollo rural implementados por los Estados están inmersos en modelos de desarrollo y teorías que a su vez responden a paradigmas de desarrollo asimilados por los diferentes gobiernos. En la actualidad se carece de análisis que relacionen la incidencia de tales modelos de desarrollo en problemáticas como el escaso relevo generacional rural.

Propósito: describir como han incidido los diferentes modelos de desarrollo rural implementados en Colombia en la problemática de escaso relevo generacional de la agricultura a pequeña escala.

Metodología: se llevó a cabo una revisión descriptiva de literatura gris, enfatizando en textos históricos del desarrollo rural en Latinoamérica y Colombia.

Resultados y conclusiones: se encontró que la implementación de modelos de desarrollo rural que desconocen la importancia de la agricultura a pequeña escala y que por el contrario sólo se han interesado en la agricultura comercial moderna ha generado el atraso, pobreza y marginación de la pequeña agricultura, y en consecuencia han forzado la migración de personas, principalmente las más jóvenes, del campo a la ciudad que salen en búsqueda de mejores condiciones laborales, seguridad, educación y mejores condiciones de vida. Se concluye que entre las principales teorías del desarrollo que han incidido en la problemática se encuentran la teoría de la modernización, la estructuralista y la neoliberal.
Perception and awareness levels of retail investors on corporate governance practices in an emerging economy.
Authors: Sandhya Sandhya , Parashar Neha
Published: February 2023

Many criteria encompass the concept of corporate governance. There is an apprehension that it’s the non-retail investors who would be interested in such governance of firms rather than retail investors, as they hold a small fraction of ownership, usually being passive investors and not in a capacity to influence the management. This study is an attempt to understand the attitude and perception of retail investors in India toward corporate governance practices and for that purpose, a questionnaire was served to consist of a range of corporate governance factors. The data was studied through percentage analysis and chi-square was run. It was established, that retail investors pay attention to corporate governance factors, more importantly to the board of directors, this finding supports the results of Chakraborty et al. (2023). But there is no strong course of action that they prefer to resolve any of their governance-related issues. India, where promoter groups are dominant, has a long way to go to bring out shareholder activism at par with developed markets

Türkiye'de 1940'lı yıllardan itibaren yaşanmaya başlanan tarımda makinalaşma ve devamında gerçekleşen sanayi atılımları; günümüzde dahi çözüme kavuşturulmayı bekleyen sorunları beraberinde getirmiştir. Sorunların en önemlilerinden bir tanesi yaşanan göçlerle ortaya çıkan konut sorunudur. 1950'li yıllarda yoğun göç alan kentlerde özellikle büyük kentlerde hızlı bir kentleşme sürecine girilmiştir. Kentlerin artan nüfusu ve kentleşme politikalarının yetersizliği nedeniyle problemler yaşanmaya başlamıştır. Kentleşme hızının artmasından günümüze kadar olan süreçte gecekondu sorunu tüm kentlerde ve özellikle büyük kentlerde görünür hale gelmiştir. Nitekim gecekondular 1990’lı yıllara gelindiğinde kentlerdeki nüfusun yarısından fazlasının barınmak için kullandığı konutlar haline gelmiştir.
Barınma ve konut sorunu dönemin önemli sorunları olarak karşımıza çıkmaktadır. Göç eden nüfusun, barınma sorununa bulduğu çözüm “gecekondular” olmuştur. Çoğunlukla sanayileşme süreci sonrası yaşanmaya başlanan ve o günden günümüze artan bir şekilde devam eden yasadışı yapılaşmaya karşı devletin geliştirdiği refleks “imar afları” olmuştur. İlki 1948 yılında Ankara için gerçekleştirilen ve 1953 yılı itibari ile tüm Türkiye'de uygulanan imar afları ile kaçak ve yasadışı yapılaşmanın önüne geçilme düşüncesi başarılı olamamış ve süreç zarfında kaçak ve yasadışı yapılaşma devam etmiştir. Türkiye’nin kentleşme tarihinin en önemli sorunlarından biri olan imar aflarının çözümü için toplam 19 tane imar affının gerçekleştirildiğini görmekteyiz. İmar aflarının çıkarılması; gecekondu ve konut sorununu çözemeyip, sorunun büyümesini engelleyememiştir. Bu çalışma ile Türkiye'de geçmişten günümüze çıkarılan imar afları dönemsel olarak ele alınıp, imar aflarının meclisteki tartışmalarda nasıl değerlendirildiğini açıklamaya çalışmaktadır.

Results: Phytochemical investigation of ethanolic extract of roots of P. persica revealed the presence of Carbohydrates, Tannins, Amino acids, Flavonoids, Steroids and Cardiac glycosides. Oral administration of Prunus persica extract (400 mg/kg) showed dose related hepatoprotective activity in Paracetamol induced liver necrosis. The parameters SGOT, SGPT, ALP and Total Bilirubin level were increased in paracetamol treated group whereas the treatment group like standard and extract decreased. The histopathological examination of the liver in the hepatotoxic animals in Paracetamol model shows liver parenchyma with distorted architecture. Some of the hepatocytes show degenerative changes, while some show apoptosis. Which were less in the treated group and regenerative hepatocytes show in treatment group? Conclusion: A significant hepatoprotective activity of ethanolic extract of Prunus persica observed in the present investigation may be due to synergistic potentiate action of its phytoconstituents since they contain a diverse array of active principles which are able to target multiple mechanisms involved in the pathophysiology of hepatotoxicity.

Antibody titer study is very important to assess the degree of undetected transmission in the community. This study aimed to estimate the antibody response to SARS-CoV-2 infection in a group of asymptomatic female workers and compare the clinical and socio-demographic parameters of seropositive and seronegative subjects in Bangladesh. This cross-sectional descriptive study was conducted among 285 female workers who had come to BIRDEM General Hospital for the COVID-19 test in November 2021 from different areas of Bangladesh.  RBD-specific antibody responses against SARS-CoV-2 were measured by using Chemiluminescent Microparticle Immunoassay (CMIA) for all participants. Overall antibody positivity was estimated at 91.9% (262), and only 8.1% of participants had a negative IgG antibody response. Of the 262 participants 96.18% were asymptomatic. In the age group, the highest seropositivity was between 21-30 years (58%). The median IgG titer of the antibody was estimated at 578.50 AU/ml. The participants of Khulna had the highest median IgG titer of 3966 AU/ml followed by other areas (p=0.043). There was no significant difference in median IgG titer in symptomatic, asymptomatic, and vaccinated, non-vaccinated participants. Based on the geographical area Dhaka and Barisal had significantly more seropositive subjects than seronegative subjects (p = 0.001) and (p = 0.011). The high number of undiagnosed COVID-19 patients in the population is reflected in the percentage of seropositive people. Our findings will assist academics in better understanding immune status and policymakers in taking proactive measures during pandemic situations and future health emergencies.

Keragaman dan perubahan iklim merupakan proses alami yang terjadi secara dinamis dan terus-menerus. Hal ini dicirikan oleh ketidak menentuan pola curah hujan dan musim, serta peningkatan frekuensi kejadian anomaly (penyimpangan) iklim. Pertanian merupakan salah satu bidang yang merasakan dampaknya secara langsung. Pertanian dengan memanfaatkan sawah tadah hujan merupakan mata pencarian utama bagi masyarakat di Nagari Parambahan Kecamatan Lima Kaum Kabupaten Tanah Datar. Petani di Nagari Parambahan, dari dulu dalam menentukan waktu tanam hanya menggunakan insting atau pengalaman bertahun-tahun dalam bertani. Padahal kondisi iklim dulu dengan saat ini sudah berbeda. Oleh karena itu, solusi yang diberikan pada kegiatan pengabdian ini adalah dengan memberikan informasi pada petani sawah tadah hujan melalui Pemanfaatan Sistem Informasi Kalender Tanam Terpadu. Kegiatan ini dilaksanakan dalam 2 tahap dimana pada tahap 1, dilaksanakan sosialisasi kepada pihak nagari dan perangkat nagari untuk meningkatkan pemahaman mengenai iklim dalam pertanian dan komoditas yang cocok ditanam. Selanjutya tahap 2 dilaksanakan dengan memberikan workshop dan pelatihan secara langsung kepada kelompok tani sawah tadah hujan dan perangkat nagari mengenai kondisi iklim dan komoditas yang cocok di tanam serta pembuatan sistem kalender tanam terpadu dengan menggunakan website. Hasil kegiatan menunjukkan bahwa dari 25 petani sawah tadah hujan, hanya 14 orang atau 64% yang mampu menguasai system kalender tanam terpadu menggunakan website dari Balai Penelitian dan Pengembangan Pertanian.
Single-domain antibody for binding the conserved epitope in the SARS-CoV-2 spike protein receptor-binding domain
Authors: Vorobyev PO , Tillib SV
Published: February 2023

Several COVID-19 vaccines have been developed in the last three years using various tecnhiques. Multiple virus-neutralizing antibodies against SARS-CoV-2 have been also obtained to combat the pandemic. However, the use of these medications for prevention and potential treatment faces significant challenges due to the emergence of new mutant virus variants, both more contagious and escaping neutralization by the immune system, that is why it is necessary to continuously renew the vaccines and develop new therapeutic antibodies. The study was aimed to use the technology of generating single-domain antibodies (nanobodies) to target the surface spike (S) protein RBD conserved epitope of the broad spectrum of SARS-CoV-2 variants. Recombinant proteins that corresponded to RBDs of three important SARS-СoV-2 strains and the full-length S protein (Wuhan) were used as antigens for immunization of a camel in order to induce production of appropriate antibodies and/or as immobilized proteins for further cross selection of the nanobody clones with pre-set specificity by the phage display. A nanobody capable of effectively recognizing the conservative region in the S protein RBDs of the broad spectrum of pandemic SARS-CoV-2 variants, including Omicron, was selected from the generated immune library. Along with conventional use in immunoassays and diagnosis, the generated nanobody can be potentially used as a module for target-specific binding used to trap coronavirus in human upper airways during the development of novel combination antiviral drugs.
