Published: November 2022

Earlier research has suggested that the male reproductive system could be particularly vulnerable to SARS-CoV-2 (COVID-19) infection, and infections involving this novel disease not only pose serious health threats but could also cause male infertility. Data from multi-organ research during the recent outbreak indicate that male infertility might not be diagnosed as a possible consequence of COVID-19 infection. Several review papers have summarized the etiology factors on male fertility, but to date no review paper has been published defining the effect of COVID-19 infection on male fertility. Therefore, the aim of this study is to review the published scientific evidence regarding male fertility potential, the risk of infertility during the COVID-19 pandemic, and the impact of COVID-19 vaccination on the male reproductive system. The effects of COVID-19 infection and the subsequent vaccination on seminal fluid, sperm count, sperm motility, sperm morphology, sperm viability, testes and sex hormones are particularly reviewed.

The interdigital gland is a specialized skin gland located between the digits of Artiodactyla (i.e., even-toed ungulates). Its secretion participates in semiochemical communication, and protects from ultraviolet radiation as well as fungal and bacterial infections of the feet. The present study aimed at finding if there are male-female differences in the anatomy, morphology, and volatile compounds of the interdigital gland of the South Indian breed of Vembur sheep. A total of 24 sheep (12 each of male and female) were spotted at the slaughterhouse and the interdigital gland was removed for examination. The anatomical examination revealed it to resemble a tobacco pipe and to consist of a body, flexure, and excretory duct with an external orifice located at the cleft of the digits. Morphometrically, the interdigital glands differed between males and females. The gland possesses a distinct fibrous capsule, epidermis, and dermis. The fibrous capsule contains several parallel bundles of collagen fibers, nerve fibers, and blood vessels, etc. The epidermis consists of keratinized squamous epithelium formed of stratum basale, stratum granulosum and stratum spinosum. The dermis consists of hair follicles, nerve plexuses, arrector pili muscles, and apocrine and sebaceous glandular lobules. The latter, lined by a simple cuboidal epithelium, are arranged in clusters of acini in the upper portion of the dermis. The apocrine secretory lobules, made up of parenchymal cells, are found in the lower portion of the dermis. The density and diameter of the apocrine and sebaceous secretory lobules were significantly higher in the males than females. Scanning electron microscopic (SEM) analysis confirmed the apocrine and sebaceous secretory components. Twenty-three major compounds were identified in the interdigital gland postings of male and female sheep, among which butanoic acid, 2-methylpropanoic acid, 1-heptanol and octadecanoic acid were present only in the male glandular post, whereas octane, 7-hexyl-tridecane, tetradecane, heptadecane and decanoic acid were present only in the female glandular post. Tetradecanol, tetradecanoic acid and hexadecanol peaks, reportedly antibacterial compounds in pronghorn antelopes, were highly prominent in both male and female sheep. Thus, the interdigital gland of Vembur sheep has two major secretory lobules, namely, sebaceous and apocrine, larger in males than females, which secrete a variety chemical compounds that may serve as chemical communication systems and protect the sheep from foot-borne diseases.

In Italy, dairy sheep farming represents a vital agro-industry sector, but it is still challenged by contagious agalactia (CA), which is endemic there, and vaccination is the most economical and sustainable tool for control. This study aimed to evaluate the combined Mycoplasma agalactiae (Ma)-Staphylococcus aureus (Sa) vaccine (Ma–Sa) against the Ma monovalent vaccine in ewes. Twelve primiparous Ma-free ewes were randomly grouped into three equal groups: first, the control group injected with placebo, second, the group vaccinated with the Ma monovalent vaccine, and third, the group vaccinated with Ma–Sa combined vaccine, with two S/C doses at 45-day intervals. The animals were examined for serological, hematological, and somatic cell count (SCC) changes for 17 successive weeks. A significant increase in anti-Ma antibody mean titers, leukocytes, and platelets was observed in the vaccinated animals, with the highest values in those who received the combined vaccine. Neutrophils were high only in the animals who received the combined vaccine. SCC was lower in the vaccinated animals during the first six weeks. This study concludes that the combined Ma–Sa vaccines enhance immune response and potentiate its efficacy against Ma. This improvement might be attributed to the sensitization/activation effect of S. aureus on platelets, which are recoded to act as a key regulator for the coordination of all components of the innate immune system. Even though this study included a small number of animals, its findings about the potentialities of this inactivated vaccine in the control of CA are strongly encouraging. Further confirmation might be needed through additional replicates and a challenge study is needed before proceeding with widespread use.

Published: November 2022

The South China Sea (SCS) plays an important role in global marine ecology. Studies of phytoplankton diversity promote the sustainable utilization of resources in the SCS. From July to August 2020, the phytoplankton community structure at 47 stations in the northern SCS was investigated. Species composition and distribution of phytoplankton, water quality, diversity index, main influencing factors, and succession characteristics of the community structure were analyzed in combination with the survey results from previous years. A total of 332 separate taxa from 83 genera and three phyla were identified, including 142 species and 45 genera of Bacillariophyta, 188 species and 36 genera of Dinophyta, and two species and two genera of Chrysophyta. Average phytoplankton cell abundance was 649.97 cells/L. Nitzschia spp., Thalassionema nitzschioides, and Scrippsiella spp. were the dominant species. Scrippsiella spp. was found for the first time as a dominant species in the northern SCS. Meanwhile, Nitzschia spp. was associated with organic-polluted water. The high-value areas of Nitzschia spp. also indicated eutrophication, and water was slightly polluted. The Shannon–Weiner diversity index of the surface layer was 0.99–4.56 (with a mean of 3.57), and the evenness index was 0.23–0.96 (with a mean of 0.83). The phytoplankton community structure in the northern SCS was deemed to be stable. Pearson correlation analysis showed that the sum of nitrate and nitrite was significantly negatively correlated with the abundance of dinoflagellate, which indicated restrictions as a result of the sum of nitrate and nitrite, with no significant correlation between ammonium salt and various groups. Small- and medium-sized phytoplankton are usually dominant in the SCS, where nitrogen is limited.
Selective Consumption of Pelagic Cladocerans by Bluegill Sunfish (Lepomis macrochirus Rafinesque) Contributes to Dominance of Epiphytic Cladocerans
Authors: Kim Seong-Ki , Choi Jong-Yun
Published: November 2022

Fish predation is restricted in areas with high aquatic macrophyte coverage; however, bluegill sunfish (Lepomis macrochirus), an exotic fish species, can consume prey even in such spaces. Here, we hypothesized that the cladoceran community structures in three wetlands (Upo, Jangcheok, and Beongae) with abundant macrophytes within the Nakdong River basin, South Korea, were influenced by high abundance and foraging activities of L. macrochirus. The study areas were dominated by L. macrochirus with body sizes < 10 cm, and their cladoceran consumption was higher than that of larger size classes. Most of the cladoceran species that were highly consumed by L. macrochirus were pelagic (i.e., Daphnia obtusa and Daphnia pulex); epiphytic species were consumed less (i.e., Chydorus shpaericus, Alona retangula, and Pleroxus laevis). We hypothesize that epiphytic cladoceran species are not easily explored by L. macrochirus. Selective consumption of pelagic species by L. macrochirus was reflected in the seasonal cladoceran distribution. Epiphytic species were the most abundant, whereas pelagic species abundance was relatively low. The low density of pelagic cladoceran species further increased the epiphytic species abundance. We conclude that the dominance of L. macrochirus introduced into Korean wetlands has been sufficient to change the cladoceran community structure; therefore, the abundance of epiphytes cladocerans in other countries or regions needs to be provided priority to the dominance and consumption pattern of L. macrochirus.
Smooth Spatial Modeling of Extreme Mediterranean Precipitation
Authors: Hammami Hela , Carreau Julie , Neppel Luc , Elasmi Sadok , Feki Haifa
Published: November 2022

Extreme precipitation events can lead to disastrous floods, which are the most significant natural hazards in the Mediterranean regions. Therefore, a proper characterization of these events is crucial. Extreme events defined as annual maxima can be modeled with the generalized extreme value (GEV) distribution. Owing to spatial heterogeneity, the distribution of extremes is non-stationary in space. To take non-stationarity into account, the parameters of the GEV distribution can be viewed as functions of covariates that convey spatial information. Such functions may be implemented as a generalized linear model (GLM) or with a more flexible non-parametric non-linear model such as an artificial neural network (ANN). In this work, we evaluate several statistical models that combine the GEV distribution with a GLM or with an ANN for a spatial interpolation of the GEV parameters. Key issues are the proper selection of the complexity level of the ANN (i.e., the number of hidden units) and the proper selection of spatial covariates. Three sites are included in our study: a region in the French Mediterranean, the Cap Bon area in northeast Tunisia, and the Merguellil catchment in central Tunisia. The comparative analysis aim at assessing the genericity of state-of-the-art approaches to interpolate the distribution of extreme precipitation events.
On the Evolution of the Optimal Design of WDS: Shifting towards the Use of a Fractal Criterion
Authors: Saldarriaga Juan , Salcedo Camilo , González María Alejandra , Ortiz Catalina , Wiesner Federico , Gómez Santiago
Published: November 2022

Several researchers have proposed methodologies for addressing the problem of designing optimal water distribution systems. Metaheuristic approximations are studied the most due to the vast solution space. In search of reducing computational time, the Non-dominated Sorting Genetic Algorithm II (NSGA-II) has been tested with retrofitting from the Optimal Power Use Surface (OPUS) methodology. A previous study demonstrates how OPUS significantly improves the results since it seeks to reduce energy losses in the network, in order to approximate minimum-cost designs using fewer hydraulic executions. However, more research is still needed to determine applicable hydraulic criteria that allow an enhanced comprehension of optimal designs. Therefore, this paper aims to understand the characteristics of near-optimal solutions using designs from the retrofitted OPUS/NSGA-II Pareto fronts of four distinct networks (Hanoi, Balerma, Fossolo, and Modena). Moreover, fractal characteristics of the networks’ energy dissipation, flow, and diameter distribution have been analyzed for this purpose. In this way, outcomes suggest that the hydraulic gradient line box dimension in optimal designs approaches a value of two, demonstrating that objects resemble a single-plane surface. These promising results propose fractal analysis as a practical design criterion due to its hydraulic significance and low computational cost.

Today, Russia tops the list of countries against which sanctions have been imposed by the world community. At the moment, 11,579 punitive measures have been introduced against the Russian Federation and persons with citizenship. The closest "pursuer" is Iran, which has only 3,637 restrictive measures in its international portfolio, which is 68.59 % less than the leader of the list. The third and fourth lines are occupied by Syria and North Korea (2624 and 2136 sanctions respectively). Belarus closes the top fi ve with 1133 restrictions.Russia took the leading position after the decision on the Special Military Operation in Ukraine was made. Until February 22, 2022, 2,754 restrictive measures were introduced against Russia (which is 76.22 % less than the current ones) in connection with the previous events in Ukraine. For example, the United States of America has doubled this value since 2014. Statistics analyzed and collected using an online restriction tracking service. Almost all countries can be noted as aff ected by the change in the architecture of the world economy. The rejection of dollar transactions, the freezing of assets of the Central Bank of Russia, the violation of the usual supply chains, the bipolarization of the world, the open violation of international law and other facts and events have spurred all states to adjust their domestic and foreign policies.Moreover, the actual development of the problem considered in this work is completely absent from the scientifi c community due to the too short period since the introduction of the last economic restrictions.Within the framework of the article, the author reveals the features of the application of economic sanctions against the Russian Federation. The article systematizes the stages of application of sanctions against the Russian Federation.
Federal debt pyramid and record budget deficits as a threat to national security of the USA
Authors:   The Institute of USA and Canada Studies Russian Academy of Sciences, Moscow, Vasiliev V. S.
Published: November 2022

The article analyzes the transformation of the problem of federal debt and budget defi cits in the United States from a sphere that has a purely economic dimension to the most acute task of ensuring the US national security. It is emphasized that the main demarcation line that predetermined the distinction between the purely economic dimension of the problem of debts and defi cits and national economic security was the ratio of federal debt to GDP, equal to 119 %, recorded in the mid-1940s after the end of World War II. This indicator was considered a benchmark for the historical strength and stability of the entire US federal fi nance system. Before the start of the fi nancial and economic crisis of 2020–2021, provoked by COVID-19 pandemic, the United States believed that they had about 10–15 years during which they could solve the problem of debts and defi cits relatively painlessly, but already in 2020 as a result "Super-aggressive" fi scal policy aimed at keeping the American economy afl oat, the United States has come close to the debt-to-GDP ratio of 130 %. Forecasts by federal government offi cials indicate that the debtto- GDP ratio will not fall below this level over the next 30 years, leaving the federal fi nance system highly vulnerable to shocks and economic blows that could potentially lead to a sudden collapse of the accumulated debt pyramid. The rapid transformation of the situation with debts and defi cits into the most acute problem of national economic security has already led to an almost complete paralysis of fiscal policy, which, in the context of the recession of 2022, turned out to be almost completely devoid of a countercyclical orientation. In addition, the US Federal Reserve took the path of using inflation to reduce the debt burden on the US economy, which predetermined the formation of a "toxic" inflationary environment both in the US and in the global economy in the near foreseeable future. The debt trap that the United States fell into at the beginning of the third decade of the 21st century predetermined the extremely aggressive forms of US behavior in the system of international economic relations, including the unleashing of economic wars, with the ultimate goal of demonstrating to the world community that the United States will never, under any circumstances, pay off their accumulated public debt, as well as the debts of other sectors of the US economy.

O presente artigo tem como objetivo apresentar as pesquisas correlatas do objeto de investigação desta pesquisa, a alfabetização no ensino inclusivo, destacando a articulação desses elementos na constituição histórica do processo educacional inclusivo. Apresentam-se no decorrer do trabalho os fundamentos e concepções da organização do processo de alfabetização e do ensino inclusivo de sua institucionalização aos dias atuais. Para isso, realizaram-se buscas de pesquisas correlatas sobre a alfabetização e ensino inclusivo no banco de produções científicas da Capes. A busca possibilitou compreender como o processo histórico de alfabetização foi organizado no decorrer dos tempos, os métodos e as teorias que balizaram o ensino e a aprendizagem da leitura e da escrita, apontando as aproximações e contradições entre os elementos que nortearam o processo. As considerações finais apontam que ao longo da história a alfabetização foi estruturada por métodos e perspectivas teóricas que conduziram o processo à fragmentação, à hierarquização e à desqualificação. Ainda, evidenciam a necessidade de compreender que a inserção no campo de  alfabetização pressupõe assumir o compromisso com a transformação social na busca pela emancipação dos sujeitos a partir do ensino e da aprendizagem dos conhecimentos científicos da leitura e da escrita.

Residência Docente e Questões LGBTTIQA+
Authors: Macêdo do Carmo Gustavo , Bassoli Fernanda
Published: November 2022

A sociedade contemporânea sustenta uma matriz heterossexual identitária dominante cujos discursos, valores e práticas instituem a heterossexualidade como a única forma de expressão natural e legítima. A escola assume um papel significativo neste processo, por meio de ações pedagógicas que, muitas vezes, resultam na marginalização de sujeitos que não se encaixam nos padrões heteronormativos. Socializamos neste artigo a construção, implementação e a análise de uma aula sobre gênero e sexualidade, voltada para o reconhecimento de diferentes grupos do movimento LGBTTIQA+ e os enfrentamentos que vivenciam em duas tramas: sociedade e escola. O trabalho foi desenvolvido no escopo de um Programa de Residência Docente, no contexto do Ensino Remoto Emergencial, na disciplina Ciências. Com base na devolutiva de atividades e discussões em aula, constatamos a sensibilidade das/os estudantes em relação ao tema e, sua importância na ruptura das bases ideológicas uniformizadoras que caracterizavam a escola do século XIX e persistem na atualidade.

Avaliação antitumoral da terapia fotodinâmica com azul de metileno em células neoplásicas mamárias
Authors:   , Souza Álvaro Carneiro de
Published: November 2022

A terapia fotodinâmica (TFD) é uma alternativa de tratamento para o câncer de mama, demonstrando seletividade e importante citotoxicidade aos tecidos malignos. Este tipo de terapia envolve o uso de dois componentes não tóxicos: uma substância fotossensibilizante e uma fonte de luz (como lasers de baixa potência). Em combinação, eles podem induzir efeitos celulares e teciduais por meio de processos dependentes de oxigênio, levando as células tumorais à morte por necrose, apoptose e autofagia. Assim, o objetivo foi avaliar a atividade antitumoral da terapia fotodinâmica utilizando células tumorais mamárias em modelos experimentais in vitro. A linhagem celular de tumor de mama 4T1 foi cultivada em meio RPMI suplementado com 10% de soro fetal bovino (SFB) e 1% de antibiótico a 37°C e 5% de CO2. O azul de metileno (AM) foi dissolvido em meio RPMI nas concentrações 5, 10, 15, 20, 25, 50, 100 e 150 µM, filtrado e as células foram incubadas durante 30 min a 37°C. Logo após esse período de incubação, a solução de AM foi removida, as placas lavadas eu um novo meio RPMI adicionado. A irradiação foi realizada com laser vermelho de baixa potência (660nm - AsGaAl), perpendicularmente e pontualmente, nos seguintes parâmetros: potência 100mW, densidade de energia 100 Jcm-2 , energia por ponto 2,8 J, modo de emissão de luz contínua e tempo de exposição 28s. Após a irradiação, viabilidade celular foi testada através de MTT, a migração celular foi realizada pelo método wound healing e níveis relativos de mRNA através de real time PCR. Os resultados de viabilidade celular indicam que as concentrações de AM de 5 a 50 µM não foram tóxicas para as células 4T1, enquanto as concentrações de 100 e 150 µM apresentaram citotoxicidade. Por outro lado, células 4T1 incubadas com AM e irradiadas com laser de baixa potência apresentaram redução da viabilidade e na migração celular na concentração de 50 µM. Níveis relativos de mRNA para caspase-6 não foram alterados nos tratamentos testados; já os níveis para Bcl-2 foram reduzidos após TFD 25 µM. Em conclusão, concentrações superiores a 100 µM de AM no tempo de incubação de 30 min geram efeitos citotóxicos nas células, reduzindo a viabilidade. Concentração de 50 µM demonstrou diminuição na viabilidade e migração celular após a TFD, indicando uma boa dose-resposta do tratamento para esse tipo de célula.

Many tensile tests are carried out to complete the basic design information of the strength of a material and as supporting data for material specifications. In the tensile test, the test object is given a load of tensile force that increases continuously, at the same time observations are made regarding the extension experienced by the test object. This study aims to determine the mechanical properties and their changes from a metal to tensile loading using qualitative methods and data collection methods using literature review. The study is carried out by collecting data through a literature book related to the object of the final project. The test results of the material that has the smallest value, namely Aluminum, are obtained, the value without heat treatment is Voltage = 566 N / mm2, Strain = 7.9 , ME = 72.1 N / mm2) and the value using heat treatment is Voltage = 439 N / mm2), Strain = 3.5, ME = 124.5 N / mm2). While the largest value, namely Iron Concrete TP 280, was obtained, the value without heat treatment was Voltage = 1012 N / mm2, Strain = 6.5 , ME = 156.4 N / mm2). While the values when using heat treatment are Voltage = 729 N / mm2), Strain = 3.7, ME =198.8 N / mm2). It can be concluded that the results of the comparative analysis of the strength of the test material without heat treatment and using heat treatment are known when the material is heated until it is close to its critical point, the material will form a new property that will make it change its properties to be tenacious or brittle.Keywords : Tensile Test, Stress, Strain, ME "Modulus of Elasticity", Heat Treatment

Published: November 2022

Rheology and the study of viscoelastic materials are an integral part of engineering and the study of biophysical systems. Tissue rheology is even used in the study of cancer and other diseases. However, the cost of a rheometer is feasible only for colleges, universities, and research laboratories. Even if a rheometer can be purchased, it is bulky and delicately calibrated, limiting its usefulness to the laboratory itself. The design presented here is less than a tenth of the cost of a professional rheometer. The design is also portable, making it the ideal solution to introduce viscoelasticity to high school students as well as for use in the field for obtaining rheological data.

Abordagens teóricas de métodos regionais na perspectiva da dialética
Authors: Carrieri Raquel Augusta Melilo , Ascenção Valéria de Oliveira Roque
Published: November 2022

É apresentada, neste artigo, parte das primeiras análises da revisão bibliográfica que compõe uma pesquisa de doutoramento. Esta pesquisa tem como um dos objetivos, e procedimentos, analisar as possibilidades da abordagem de regionalização na geografia escolar que permitam o desenvolvimento do raciocínio geográfico. Por isso, justifica-se o enfoque sobre método regional. Apresenta-se, neste artigo, a investigação do método regional nas correntes de pensamento associadas à geografia crítica. Os dois métodos regionais que serão apresentados, e contrastados, foram defendidos por Aluízio Duarte e Roberto Lobato Correia. O primeiro geógrafo advoga a aplicação do conceito de totalidade como suporte de análise e divisão regional. Já Roberto Lobato Correia defende a aplicação de uma das leis da dialética no processo de divisão regional:  a lei do desenvolvimento desigual e combinado. Apesar das diferenças, os dois autores atribuem as mudanças na estrutura dos espaços às forças do capital internacional. Não há, entre essas e diversas outras opções teóricas, um método acabado e mais correto. Há aquele que se adequará, em termos de linguagem e conteúdo, às questões de pesquisa.

The solid-state formation of gallium antimonide on Si(111) from a stoichiometric mixture of GaSb in the temperature range of 300 °C–500 °C and thicknesses of 12–40 nm was studied under ultrahigh vacuum conditions. The influence of the preformed GaSb seed islands on the morphology, composition, and structure was studied. It has been found that at 300 °C a strained continuous polycrystalline film is formed, which rupture at 350 °C. It has been shown that a continuous single-crystal GaSb film grows at 400 °C–500 °C if the sample is annealed at a weak antimony flow. This is also facilitated by the preliminary formation of a high density of nanosize GaSb seed islands. As a result, a continuous relaxed film with epitaxial relations GaSb(111)∣∣Si(111) and GaSb[1–10]∣∣Si[1–10] was obtained from a GaSb mixture 40 nm thick at 500 °C. We demonstrate a possibility of direct formation of GaSb on Si(111) without buffer layers of other chemical elements.
