Abstract: Bangladesh's first access-controlled expressway is the Dhaka-Khulna (N-8) Expressway. The project consists of 8 lane road of 55 km length, 54 culverts, 20 underpasses, 2 interchanges, 4 major bridges, 25 minor bridges, and 5 flyovers. Teghoria Interchange of this project is structured with 19 Reinforced Earth Wall, out of which a crack appeared in a wall that has 146 meters length and 7 meters height. Detailed inspection and analysis were followed by repair and rectification work. The aim of this paper was to find out the likely causes of this crack, discuss detailed retrofitting methodology and bring forth some recommendation. This crack may form due to weak workmanship during compaction and installation of tendons of reinforced earth, environmental load, heavy-loaded vehicle travel above the RE wall etc. The specialist team of the consultants of the project and experts from development partner inspected the problem and worked out how to repair the cracked area. The development partner developed repair methodology and executed the crack repair work as well as the treatment plan under strict supervision of consultants. Surface preparation, preparation of precast veneer & epoxy-based mortar, placement and finishing work make up the treatment process.

Published: December 2022

Abstract: There are many situations in which the I-Sections used in construction are subjected to moments about their weaker axis, i.e. the y-y axis. For such purposes the Plastic Section Modulus about y-y axis becomes necessary. In the present paper an attempt has been made to calculate and present the values of Zpy, for I.S. Rolled Steel Beam Sections (with tapered flanges). Since IS 800 : 2007[2] has not given the values of Zpy, of any section, one tapered flange I-Section, viz., 125 TFB @ 13.1 kg/m, from “Onesteel” (Australia),[4] has been used to ascertain the correctness of calculations. The results are presented in table form in descending order.

Authors: Deka Dhrubajyoti , Das Dr. Bharati Medhi
Published: December 2022

Abstract: Urban flood is one of the major problems in Guwahati city at present. The topography of the city is such that rainwater cannot drain out easily from the city. With rapid growth of the city, along with people cutting and constructing houses in the surrounding hills, result in high sediment yield from the immediate upper catchment, adding another dimension to this problem. The need for a proper storm water disposal drainage system is at prime in Guwahati. Therefore innovative planning and efficient design of the drainage network is necessary. An effort has been made to study finer details of the area by investigating drainage systems of various parts of the city. The existing drainage channel is studied and simulated using SWMM 5.1 modeling software. The model is simulated for rainfall of two-year return period of interval one-hour design storm intensity. Frequency analysis is performed using best fitted distribution i.e., Gumbel’s distribution for different return periods and the frequency values are used for development of IDF (intensity-duration-frequency) curves. The city is divided into major flood prone areas according to ASDMA and then modeling is done with respect to different return period of rainfall. From simulation it is found that the existing drainage of the city is not efficient to drain out the storm-water completely, the primary cause of urban flood in Guwahati city

Authors: Naumova Nina A.
Published: December 2022

The aim of the study was to determine effectiveness of the use of microbiological agents in spring barley cultivation. The experiments were conducted in the conditions of light chestnut soils in the north of the Astrakhan region, Chernoyarsky district, Solenoe Zaymishche village in 2018-2020. The use of this cultural method contributed to two-fold increase in the productivity of spring barley (3.5 t/ha), compared with the control (without any seed treatment - 1 .4 t/ha). The pre-sowing inoculation of seeds increased field germination and number of mature plants: by 75 and 26.8 % for Mizorin, 79 and 40.9 % for BisolbiFit, 78 and 37.6 % for Rizoagrin, respectively, in comparison with the control. Application of these microbiological agents in spring barley cultivation can be recommended to both small and large farms, which will help to rise the agriculture of the region to a high level of production of spring barley.
Identification of Pseudomonas fuscovaginae, Pseudomonas syringae and Xanthomonas translucens in wheat seeds using PCR
Authors: Muvingi Mufaro , Slovareva Olga Y. , Zargar Meisam
Published: December 2022

The causative agents of grain crops bacteriosis viz. Pseudomonas fuscovaginae , Pseudomonas syringae and Xanthomonas translucens are regulated by phytosanitary requirements of the largest importers of Russian grain - Egypt, Turkey, Bangladesh, Nigeria and Pakistan. Therefore, it requires the development of rapid methods for their diagnosis. The PCR method, which is the fastest and most reliable in testing laboratories, needs optimal preparation of the test material. The aim of the study was to optimize the process of preparing seed samples for subsequent detection and identification of P. fuscovaginae, P. syringae and X. translucens by PCR. Wheat grain samples were soaked in phosphate-buffered saline (PBS) for 2 hours and infected with suspensions of P. fuscovaginae, P. syringae pv. coronafaciens and X. translucens at various concentrations. Then, the infected grain samples were crushed and subjected to two-stage centrifugation. DNA was isolated from the obtained analytical samples and species-specific PCR was performed for each bacterial species. It was found that a two-hour soaking of the seeds and their treatment with a homogenizer is sufficient to effectively destroy each grain in the sample and ensure the release of bacteria into the liquid part of the sample. The first low-speed centrifugation allowed the crushed grain to settle efficiently and remove excess starch from the supernatant. High-speed centrifugation of the supernatant made it possible to obtain a concentrated microbiota contained in the grain sample. To obtain DNA of sufficient quality for PCR test, the kit Proba-GS (AgroDiagnostika, Russia) was used for DNA extraction. Using Pseudomonas fuscovaginae-RT kit (Syntol, Russia) and PsyF/PsyR and 4F1/4R 1 primers, DNA of P. fuscovaginae P. syringae and X. translucens , respectively, was successfully detected in each of the samples infected with these bacteria at concentrations of 103 CFU/ml. The absence of PCR inhibition was noted. The method of removing starch from samples for molecular diagnostics of phytopathogens was used for the first time. Application of these methods will allow diagnosing pathogens of bacterioses within one day.

Authors: Medvedeva Lyudmila  N. , Zorkina Olga  V. , Moskovets Maria V.
Published: December 2022

Some aspects of improving efficiency of quail breeding in Russia, in particular in private farms were studied. It is emphasized that in times of crisis, private farms are able to solve several problems: provide employment for rural residents, produce food, and serve as a source of additional income for people. In Russia, consumption of animal protein in poultry meat has increased to 34 kg. The aim of the research was to study the issues of breeding quails on small plots, at private farms; the use of Chlorella vulgaris microalgae in the diet of poultry, which has become intensively used in various sectors of the economy, in particular, in animal husbandry and improvement of natural reservoirs. Methods of analysis, observation, experiment, comparison were used in the course of the study; photographing and timing of resources spent on the maintenance of quail birds was carried out. The Russian and foreign scientific literature was studied, the presented material was compared with the results obtained during the experiment. One aspect of successful quail breeding is to ensure a balanced diet - composition of feeds produced by local producers for quails was studied. The observations and experiments carried out on Moscow White Giant quails at E. Moskovets private farm (Volgograd region) proved the expediency of introducing into the diet a feed additive - a strain of Chlorella vulgaris IFR C.111, which contains protein, carbohydrates, fats, vitamins, mineral salts, trace elements in sufficient quantities. The technology of poultry feeding with Chlorella vulgaris was shown. It resulted in higher survival rate of quails, increase in poultry live weight, and increase in profitability of production by 1.3 %. Data reflecting the conditions of quail keeping, feeding and cage breeding in small areas and/or private farms were shown.

Published: December 2022

The study presents an assessment of variability of histological structure, measurement, and comparison of size of the neoplasm obtained by ultrasonographic examination and pathological examination, as well as the morphometric dimensions of nuclei and cytoplasm of testicular interstitial cell tumors in dogs. The study involved 35 dogs with neoplasms of 46 testes, where 11 animals had interstitial cell tumors in both testes. Insignificant differences of the size of these neoplasms were revealed (p 0.05) using ultrasonography and pathoanatomical measurement methods. Hence, it allows using both methods to assess the size of interstitial cell tumors. In the study, interstitial cell tumor was detected in both testes at once in 50 % of cases in dogs, however, this might be due to specific characteristics of the sample, and further research is required. In the course of scientific work, a morphological study showed the presence of variability in histological structure of interstitial cell tumors, which can lead to incorrect interpretation of the morphological picture and misdiagnosis, e. g. adipocyte-like morphology of interstitial cell tumors have morphological similarity to a benign neoplasm from adipose tissue - lipoma. In addition, there was an extremely pronounced difference in size of cytoplasm (from 23.6 to 148.4 m; average 66.21 22.42 m) and nuclei (from 9 to 57.6 m; average 23.19 7.10 m) in tumor cells. It proves the presence of pronounced anisocytosis and anisokariosis, which should indicate malignancy of the neoplasm, however, testicular interstitial cell tumors extremely rarely metastasize in practice and according to numerous studies.

Authors: Gupta Jatin , Kumar Sharma Manoj , Kumar Kumawat Dr. Mukesh
Published: December 2022

Abstract: Customers can visit and purchase medications from e-pharmacies online without visiting a pharmacy. However, there are always two sides to every story. Some clients choose to buy prescription drugs online. Anyone can now purchase anything online, including groceries, clothing, and electronics, thanks to the advancement of digital technology and the expansion of ecommerce platforms. As a result, purchasing prescription medications online has emerged as the new standard during this pandemic crisis. E-pharmacies are a cutting-edge and fascinating business idea that has the potential to revolutionize the healthcare sector. By doing away with middlemen, these online pharmacies that are entering the Indian market want to improve the availability of pharmaceuticals. This research attempts to examine and analyze the changing trends in medicine purchases. The project's objective is to understand how customers feel about online pharmacies and whether or not they will utilize them in the future. The sample size for the study was 520, and 12 items were included in the questionnaire presented to respondents. The results show that although only 46.34 per cent of respondents currently use e-pharmacies, 89.03 per cent of respondents are willing to use them in the future. According to the survey questionnaire, contactless delivery and convenience were the main factors influencing people to buy drugs from online pharmacies. The study sample could not be typical of the overall population of India, which is the research's main flaw. Despite the gradual pace, people are starting to change how they buy drugs from online pharmacies. The COVID-19 outbreak made drug purchases through online pharmacies easier.

For the Russian Federation at the present stage the issue of further strengthening the Russian nation has been updated. This process of searching for optimal ways involves politicians, representatives of the expert and scientific community. The purpose of the article is to conduct a systematic analysis of the modern Russian nation as an ethno-political phenomenon. At the same time, this analysis is presented by the author from the standpoint of two methodological approaches: constructivism and primordialism. Research methods: structural-functional method, system method, content analysis method. Within the framework of the study the authors have come to the following conclusion. The results of the study - authors proved that the high interethnic conflict potential in modern Russia is due to the fact that the Russian society has not formed into a single ethnonation. Russian society is a nation only in the civil law aspect. In the ethnopolitical perspective, the Russian nation is a multi-ethnic conglomerate, moreover, with the presence of negatively complementary ethnic groups with a potentially high conflict potential.

Authors: Mohanty Sanjit Ku. , Das Debasish , B. Dash Rajani
Published: December 2022

An efficient adaptive scheme based on a dual mixed quadrature rule of precision eleven for approximate evaluation of line integral of analytic functions has been constructed. At first, the precision of Gauss-Legendre four point transformed rule is enhanced by using Richardson extrapolation. A suitable convex combination of the resulting rule and the Gauss-Legendre five point rule further enhances the precision producing a new mixed quadrature rule . This mixed rule is termed as dual mixed Gaussian quadrature rule as it acquires a very high precision eleven using Gaussian quadrature rule in two steps. An adaptive quadrature scheme is designed .Some test integrals having analytic function integrands have been evaluated using the dual mixed rule and its constituent rules in non- adaptive mode. The same set of test integrals have been evaluated using those rules as base rules in the adaptive scheme. The dual mixed rule based adaptive scheme is found to be most effective.

Linear Regression Model Using Bayesian Approach for Iraqi Unemployment Rate
Authors: Ali Ali Hussein , H. Kadhim Tasnim
Published: December 2022

In this paper we used frequentist and Bayesian approaches for the linear regression model to predict future observations for unemployment rates in Iraq. Parameters are estimated using the ordinary least squares method and for the Bayesian approach using the Markov Chain Monte Carlo (MCMC) method. Calculations are done using the R program. The analysis showed that the linear regression model using the Bayesian approach is better and can be used as an alternative to the frequentist approach. Two criteria, the root mean square error (RMSE) and the median absolute deviation (MAD) were used to compare the performance of the estimates. The results obtained showed that the unemployment rates will continue to increase in the next two decades.

The Reality of the Barracks Culture of the Korean Armed Forces of Generation MZ and the Search for Alternatives
Authors:   J-Institute, Seo Junhyeok , Yun Jiwon , Jo Youngjun
Published: December 2022

Purpose: The purpose of this paper is to analyze the characteristics of Generation MZ in the reality of the Korean armed forces where most of the enlisted soldiers are Generation MZ, and consider the task of improving the barracks culture for them.
Method: Literature study and empirical data were carried out including books, academic journals, and disser-tations related to the barracks culture’s improvement and generation MZ in order to analyze the justification and promotion strategy of barracks culture improvement and a barracks culture improvement plan appropriate for the characteristics of the military organization and Generation MZ.
Results: In order to improve the barracks culture appropriate for the characteristics of Generation MZ, the Korean armed forces need such measures as the strengthened authority and responsibility of the soldiers and allowed use of mobile phones. Furthermore, as a measure to establish military discipline, punishment for human rights, security, and negligence related issues need to be strengthened. Generation MZ lack personal experiences, and hence, group counseling ought to also be facilitated. Such policies targeting Generation MZ will be meaning-ful policies for the Generation Alpha who will enlist in the military in the future.
Conclusion: Given the nature of the Republic of Korea, which has adopted the conscription system, the military ought to be able to play the role of the last public education institution. The military ought to be able to help the Republic of Korea take a large leap toward becoming a world-class nation by recovering the hopes and dreams which Generation MZ, called the Generation of 7 Losses, lost, and developing on their own. If the military pro-moted barracks culture improvement can create synergies in tandem with the independent and enterprising characteristics of Generation MZ, the Republic of Korea will not only be able to take a new leap forward compa-rable to the miracle of the Han River, but will also become a leading nation qualified to spearhead the future of the world.
A data-driven optimal control method for endoplasmic reticulum membrane compartmentalization in budding yeast cells
Authors: Laadhari Aymen , Barral Yves , Székely Gabor
Published: December 2022

We present a framework to model and provide numerical evidence for
compartmentalization in the yeast endoplasmic reticulum. Measurement
data is collected and an optimal control problem is formulated as a
regularized inverse problem. To our knowledge, this is the first attempt
in the literature to introduce a PDE-constrained optimization
formulation to study the kinetics of fluorescently labeled molecules in
budding yeast. Optimality conditions are derived and a gradient descent
algorithm allows accurate estimation of unknown key parameters in
different cellular compartments. For the first time, the numerical
results support the barrier index theory suggesting the presence of a
physical diffusion barrier that compartmentalizes the endoplasmic
reticulum by limiting protein exchange between the mother and its
growing bud. We report several numerical experiments on real data and
geometry, with the aim of illustrating the accuracy and efficiency of
the method. Furthermore, a relationship between the size ratio of mother
and bud compartments and the barrier index ratio is provided.

Authors: Faizal Bini , Nair Lakshmi , Pavithran Jayanthy , Moni Merlin , VS Sheejamol
Published: December 2022

Abstract Objective: To analyse the role of surgery along with
antimicrobials to improve clinical outcomes in treating refractory cases
of skull base osteomyelitis (SBO). Study design and setting: A
prospective comparative study in a tertiary care centre with 70 SBO
patients meeting eligibility criteria. Participants: The study
population comprised 35 patients refractory to systemic antimicrobials
of at least four weeks duration who later underwent surgery in addition
to medication (surgical group). They were compared with a medical group
that responded to medications alone. Main outcome measures: The outcome
variables studied were the resolution of clinical features (pain,
discharge, radiology, and inflammatory markers), culture yield, and
total duration of treatment. Results: According to our study, relief of
pain was faster in the surgical group(1.66 against 4.57 months) with
statistical significance (p< 0. 001). Relief of symptoms
(p< 0.001), radiological improvement (p= 0.001), and
normalizing of inflammatory markers (p<0.001) were better in
the surgical group than in the medical group. The duration of treatment
was an average of 9. 2 months in the surgical group compared to 11.3
months in the medical group (p= 0.019). Microbial culture from deep
tissue sampling was positive in 24 surgical patients (68.57%).
Conclusion: The treatment response to surgery and antimicrobials in
treating refractory cases of SBO was better than the group who responded
to antimicrobials alone. Surgery provided higher microbial yield
resulting in culture-specific antimicrobials. The surgical group
observed faster relief of symptoms, reduced hospital stay, and total
treatment duration.

Setting: Otolaryngology and Pathology Departments, Suez Canal University
Hospital (Ismailia, Egypt). Participants: Twenty five patients. Main
outcome measures: EGFR expression is linked to early neoplastic
transformation, cellular proliferation, and the metastatic process in
laryngeal cancer. Twenty paraffin preserved primary laryngeal squamous
cell carcinoma (LSCC) and their cervical lymph nodes stained with
hematoxylin & eosin and EGFR using immunohistochemical technique with
scoring system. Results: EGFR expression in occult metastasis was
associated with higher T stage (p=<0.001) and higher tumor
grade (p=0.001). EGFR expression in occult metastasis was correlated
with primary LSCC cartilage invasion (p=0.05), lymphovascular invasion
(p=0.028) & muscle invasion (p=0.05). Laryngeal expression of EGFR and
cervical lymph node metastasis as evidenced by EGFR immunohistochemical
staining (p=0.001). Conclusion: EGFR immunohistopathological analysis of
the lymph nodes and the primary tumour is a highly valuable tool for the
detection of the cervical metastatic status and the N stage. Key words:

Published: December 2022

Wind turbines often suffer from lightning strikes, iceing and other
disasters. The installation of an electrothermal ice-melting device on
the blade can effectively remove icing, but it will increase the risk of
lightning strikes on the blade. In order to study the change of lighting
attachment manner and the reliability of the existing standard lightning
protection device after the blade is retrofitted with ice-melting
device. This paper designs a 1:30 scaled-down rotatable 3WM ice-melting
wind turbine blade for long gap lightning discharge test. Comparing the
interception efficiency of the lightning receptors before and after the
installation of the ice-melting device on the blade, the results show
that when the lightning leader develops on the windward side of the
blade, the ice-melting blade has the phenomenon of lightning receptor
failure, lightning strike at the junction of the ice-melting device and
the blade body. In the most serious case, the protection efficiency of
the lightning receptor is only 55%. The ice-melting device ‘ shields ’
some of the lightning receptor, and the charge around the blade is
distributed in an arc shape after the blade rotates, so that the
ice-melting device is broken down at a lower voltage. Through the
lightning strike probability model of ice-melting blade, it is found
that there is a great risk of lightning at the junction of ice-melting
device and blade body. The results reveal the lightning attachment
manner of the ice-melting blade and further guide its lightning
protection design.

A literatura de cordel se configura como uma das principais representantes da cultura popular brasileira, sendo considerada patrimônio cultural do Brasil. Tendo em vista essa importância, nos últimos anos, diferentes pesquisas vêm destacando diversas potencialidades do seu uso no contexto escolar. Dessa forma, neste trabalho, focamos nossas atenções nos cordéis que trazem como tema central conhecimentos relacionados à ciência da natureza. Nesse sentido, ao longo do artigo buscamos responder a seguinte questão de pesquisa: em que medida cordéis científicos podem ser pensados e utilizados no ensino de química, de modo que apresentem todo o rigor formal exigido na literatura e possibilitem alcançar propósitos educacionais relevantes para a área? Portanto, propomos como objetivo principal do trabalho elaborar diferentes cordéis científicos, seguindo o rigor da literatura de cordel, analisando o material elaborado quanto às suas limitações e potencialidades para serem utilizados no contexto educacional da área de Ensino de Química. Desta maneira, metodologicamente, apresentamos três cordéis científicos, que foram elaborados por um dos autores, juntamente com a análise do material produzido e sugestões para seu uso. Como forma de garantir que os poemas apresentassem as características desejadas, eles foram enviados para diferentes poetas cordelistas e diferentes pesquisadoras da área de ensino de química para serem analisados. A análise dos poetas nos revelou que os cordéis seguem as regras exigidas na literatura, enquanto a análise das pesquisadoras apontou diferentes potencialidades e limitações em relação ao seu uso no contexto educacional. Ao final do trabalho, apresentamos para cada cordel um quadro orientador para auxiliar na utilização do material produzido. Nos quadros são apresentadas diferentes informações a respeito dos poemas, como sugestões de atividades, conteúdos a serem trabalhos, metodologias potencializadas, aspectos interdisciplinares e possíveis limitações que podem surgir em uma intervenção educativa.

O Centro Integrado de Educação em Ciências – Escola Ciência Viva de Vila Nova da Barquinha (Portugal), resulta da colaboração entre o poder político local, a Universidade de Aveiro e a comunidade escolar. Trata-se de um centro de ciência que vive dentro de uma escola, alicerçado em temas locais e aberto à comunidade. É um exemplo pioneiro da concretização de uma perspectiva integrada de educação em ciências, articulando investigação em educação, formação inicial e contínua de professores e educação formal e não formal de ciências, desde 2013. Com a finalidade de identificar os possíveis contributos desta perspectiva para a promoção do ensino das ciências desde os primeiros anos de idade, coletaram-se dados através de inquéritos por questionário a 18 educadores/professores, 441 alunos e 106 pais/encarregados da educação; e, também, por entrevista a 17 educadores/professores e 5 monitores. Recorreu-se à análise estatística descritiva e de conteúdo para as respostas fechadas e abertas, respectivamente. Os resultados evidenciaram que os diferentes atores envolvidos têm percepções muito positivas sobre as práticas de ensino, as aprendizagens desenvolvidas e o gosto pelas ciências em contexto formal e não formal. O estudo evidencia as potencialidades da operacionalização da perspectiva integrada de educação em ciências, podendo inspirar outros contextos educativos, nomeadamente pelo seu contributo para a promoção da literacia científica desde os primeiros anos de idade e ao longo da vida.

Desde as últimas décadas pesquisas apontam alguns desafios encontrados no Ensino de Física, entre esses estão o ensino descontextualizado, tendo como foco a preparação dos estudantes para testes, resultando numa aprendizagem marcada pela memorização de fórmulas matemáticas e conceitos. Buscando minimizar esses desafios, pesquisas vêm propondo metodologias alternativas com a intenção de auxiliar o professor durante o processo de ensino e aprendizagem. Entre as metodologias propostas, destacamos as sequências de ensino no formato de Unidades de Ensino Potencialmente Significativas (UEPS), essa metodologia didática é fundamentada nos princípios da teoria da aprendizagem significativa. Desse modo, o objetivo dessa pesquisa é identificar as contribuições e limitações das UEPS investigadas em trabalhos científicos por meio de uma Revisão Sistemática da Literatura. Para alcançar esse objetivo realizou-se a busca de publicações por meio do Portal de Busca Integrado da Universidade de São Paulo (USP), utilizando as palavras-chaves "Unidade de Ensino Potencialmente Significativa" e sua terminologia em língua inglesa e espanhola, como também as siglas "UEPS" e "PMTU". A partir de uma triagem inicial e da leitura flutuante dos artigos foram criados critérios de inclusão, exclusão e de qualidade, sendo selecionados 12 artigos. A partir dos resultados da análise, os artigos foram agrupados em duas categorias: formação continuada e construção de conceitos, conforme a finalidade da aplicação da UEPS. Por meio da análise foi possível identificar as contribuições e as limitações das UEPS apresentadas nos artigos, bem como verificar a existência de lacunas presentes na literatura. Para os trabalhos futuros que pretendem adotar a abordagem quantitativa sugere-se a avaliação formativa dos participantes durante toda a aplicação da pesquisa. Além da realização de investigações buscando a formação inicial ou continuada de professores. Bem como pesquisas que investiguem a construção de conceitos nos anos finais do fundamental e na educação de jovens e adultos.
