A New Method of Water Supply in Crisis Situation
Authors: Szpak Dawid , Szczepanek Agnieszka
Published: September 2023

When it is not possible to supply water through the water supply network, it is necessary to use other resources of the water supply company, e.g., water tanker. This requires maintaining the efficiency of alternative water sources (in terms of quality and quantity). This work focuses on the possibility of using water accumulated in water pipes in a crisis situation. This work proposes a drain well to supply the population with water in a crisis situation. Thanks to this solution, the function of water supply drainage can be combined with the possibility of obtaining water accumulated in water pipes in crisis conditions. In addition, the standards for water demand in a crisis situation are analyzed. This work extends the view on the problem of water supply to residents in a crisis situation by taking into account a new solution that allows the consumption of water accumulated in water pipes.

The aim of this study is to evaluate the occurrence of weeds under conditions of limited herbicide use due to the protection zone of water resources. A total of 23 weed species were found in maize stands, 19 species were found in wheat stands, and 16 species were found in rapeseed stands. The redundancy analysis (RDA) results show significant differences in weed occurrence and composition due to herbicide regulation in each crop. Changes in weed composition induced by herbicide application limitations lead to a preference for more specialized weed species (specialists) at the expense of widespread species (generalists). Limiting the use of pesticides in sensitive and vulnerable areas, such as water sources, bodies, and watercourses, is justified from the perspective of protecting the aquatic environment and biodiversity. However, such measures can cause weed growth that is difficult to control, and therefore, it is important to search for new methods for weed control in field crops. Determining a balance between safeguarding water resources and addressing agricultural challenges remains crucial for sustainable land and water management.

The accelerated deterioration of water quality in the city of Tarija, Bolivia, has caused several water sources in the Municipality of Tarija to be discontinued due to the presence of toxic contaminants. The current water purification systems that are used in Tarija do not guarantee the elimination of heavy metals; in addition, political and social interest conflicts are a serious problem in the execution of projects and new public investment alternatives, with these being the main problems found in the sector. Reverse osmosis (RO) water purification technologies are one of the most effective contemporary alternatives for the elimination of contaminants in water, such as heavy metals; however, their application and implementation in countries with little or no experience in this type of technology require acceptance and knowledge on behalf of the interested parties. Political and social conflicts between interested parties generate scenarios that affect hydrological planning. Analysis of the actors in the urban and municipal sphere of the city of Tarija, Bolivia, provides a case study for adequate water governance and enabled us to come to a consensus for the implementation of RO. The results show 23 fundamental actors in water management in the Municipality of Tarija, with local actors being those with the greatest influence and power in decision-making. Our analysis of social networks showed an important polarization in the power of decision makers, with municipalities and legislative entities being those that decide on public investments. The interested parties showed considerable interest in the application of RO as a technology that can provide definitive, short-term solutions to the problems of water stress and the water crisis in the Municipality of Tarija and its application in small towns with a high level of social and environmental vulnerability.

A promising direction for the development of the poultry industry is to expand the range of products and improve its quality indicators. One of the ways to solve this problem may be the breeding of geese. The success of the further development of goose breeding will largely be determined by the level of breeding work, complete feeding, the technology of poultry housing used, as well as the prime-cost of the products and their quality characteristics. The expediency of producing goose products will be eff ective only when breeding highly productive breeds and lines of geese that ensure the competitiveness of farms in the domestic and foreign market. The purpose of the research was to study the eff ect of the use of domestic enzymes Amylosubtilin G3x, CelluLux-F and Protosubtilin G3x in geese compound feed on the yield of down and feather raw materials. The scientifi c and economic experiment was carried out on purebred young geese of Lindov breed. The geese (males and females) were normally developed and healthy. In order to conduct the experiment, three groups of young gees (control and two experimental ones) were formed on the principle of analog groups with respect to origin, sex and live weight, 60 heads (30 males and 30 females) in each group. The duration of the trial period was 77 days. The goslings of the 1st experimental group received the enzymes Amylosubtilin G3x and Protosubtilin G3x together with the compound feed, for the goslings of the 2nd experimental group the compound feed was enriched with the enzyme drugs Amylosubtilin G3x and CelluLux-F. It was found on the base of the results obtained that the use of a mixture of domestic enzyme drugs as part of the compound feed of the geese of Lindov breed improves the indicators of down and feather productivity of young animals. The highest amount of down mass in male geese was obtained in the 1st and 2nd experimental groups, which was 11,0 and 13,1 % higher compared to the herdmates of the control group, respectively. In female geese, this advantage was 15,0 and 18,0 %, respectively.

The purpose of the research was to study in a comparative aspect the bioelemental status of sires of Kholmogorskaya breed under different natural and climatic conditions after a long winter period of using. The work was performed at the Federal Research Center for Animal Husbandry named after Academy Member L. K. Ernst, Russian State University of National Economy named after V. I. Vernadsky and on the basis of JSC “Head Center for Reproduction” (Moscow region) and JSC “Arkhangelsk Bull Stud” (Arkhangelsk region). In the experiment the sires of JSC “Arkhangelsk Bull Stud” (n = 6) and JSC “Head Center for Reproduction” (n = 5) were used. Biochemical parameters of blood were studied such as total protein, albumin, globulin, albumin-globulin ratio, total cholesterol, creatinine, urea, ALT, AST, total bilirubin, as well as macronutrients: calcium, phosphorus, calcium-phosphorus ratio, and trace elements: iron, magnesium, chlorides, copper, zinc, and alkaline phosphotase and glucose in a comparative aspect. A comparison of protein and lipid metabolism in breeding bulls, depending on the region, showed the following results. The diff erence between the sires of JSC “Head Center for Reproduction” and JSC “Arkhangelsk Bull Stud” in total protein was 8,75 g/l or 10,2 %, albumin by 27,5 %, total cholesterol by 42,2 %, creatinine by 11,5 %, urea by 58,8 %, ALT by 8,8 %, total bilirubin by more than 200 % in favor of the sires of JSC “Head Center for Reproduction”, the ratio between A/G by 32,6 %. However, signifi cant differences (p < 0,05) were found only in the content of urea and total bilirubin. It was concluded as a result of the research that the sires of JSC “Arkhangelsk Bull Stud” need to balance the ration in protein. and mineral content. In order to determine the needs of breeding bulls for essential elements, they should be monitored regularly, at least twice a year in blood serum taking into account the defi ciency or excess intake into the body according to the results of chemical analysis of water, soil and basic feeds, and compensated with targeted premixes.
Numerical Analysis of the Effect of a Three-Dimensional Baffle Structure with Variable Cross-Section on the Parallel Flow Field Performance of PEMFC
Authors: Pei Xuejian , Yan Fayi , Yao Jian , Lu He
Published: September 2023

In this study, a 3D model of the proton exchange membrane fuel cell is established, and a new 3D baffle structure is designed, which is combined with the parallel flow field and then optimized by numerical simulation methods. The number of baffles and the cross-sectional trapezoidal base angle are taken as the main variables, and their impacts on the performance indexes of the cathode side are analyzed. The results show that the 3D baffle can facilitate the convection and diffusion mass transfer of reactants, improve the uniformity of oxygen distribution, enhance the drainage capacity, and make the cell performance superior; however, too small angle will lead to excessive local convective mass flux, resulting in the decrease of the overall uniformity of oxygen distribution and lowering the cell performance. Among them, the optimal number of baffles and angle are 9 and 58°, respectively, which improves the net output power density by 10.8% than conventional flow field.
Ensino Religioso na BNCC e (De)colonialidade do Saber na Escola Pública
Authors: Pozzer Adecir
Published: September 2023

Embora a definição da Base Nacional Comum Curricular (BNCC, 2017) seja objeto de uma série de críticas devido ao seu suposto alinhamento às visões empresariais de educação, a definição de uma diretriz curricular para o ensino religioso representa um alargamento dos horizontes de compreensão quanto a sua finalidade na escola pública. Solidifica, em certa medida, uma concepção que reconhece e valoriza a diversidade religiosa brasileira e mundial e, com isso, instaura um processo decolonial do conhecimento escolar relativo ao componente curricular que, historicamente esteve associado aos pressupostos doutrinários e interesses de religiões hegemônicas. Desde uma perspectiva crítico-compreensiva e articulando pressupostos teórico-metodológicos das Ciências da Religião e da Educação, nossa reflexão se concentra nas aberturas, desafios e possibilidades de diálogos interculturais, inter e transdisciplinares. Consideramos, assim, que o ensino religioso pode contribuir com a ampliação de compreensões contra hegemônicos e fomentar perspectivas dialógicas em processos formativos formais de educação na escola pública, desde que, ele próprio, não seja reduzido ao papel reificador do humano, incapaz de problematizar representações sociais preconceituosos sobre o outro e de reconhecer o respeito às distintas identidades, espiritualidades e alteridades.

CHRISTIAN SECULARISM AND RELIGIOUS ACCOMMODATIONS IN REPUBLICAN BRAZIL
Authors: Brasil de Souza Guilherme
Published: September 2023

The following work attempts to trace the historic roots of the Brazilian government’s discrimination towards the religious freedom rights of Jews and Sabbatarian Christians exhibited in the application of the ENEM in 2009 and 2010. This research article defends the thesis that the modern Brazilian Constitutional arguments for denying religious accommodations on national exams for Sabbatarians on grounds of laicite, state preference of religion or equality under the laws derive from an anti–liberal legal Brazilian tradition. This paper diachronically argues that this tradition of denying exemptions for minorities developed as a result of Brazil’s republican history and authoritarian dictatorial past in order to promote a particularly secularized Christian establishment.

This paper begins by tracing the historical roots of legal arguments for denying religious accommodations for religious minorities in Brazilian republican constitutional history. It then shows how Brazilian elites used a secularized Catholic-positivistic discourse in the first half of the 20th century to suppress minority religious rights presupposing that Brazil was uniquely a Christian (i.e Roman Catholic) nation. The paper will then proceed to show how this Catholic positivistic discourse evolved to a more covert “secular” argument such as those from equality under the laws, “isonomy” and the secular nature of the State, “laicité” following the 1960s and thereafter. The second section attempts to show how this covert anti-liberal tradition of secularized Christianity has still been maintained in Brazil’s 1988 social democratic constitution by the discourse of isonomy and laicité. The article then concludes by attempting to show how religious accommodations do not harm government and suggesting that greater coalition building between minority religions can benefit both historically marginalized communities. This paper concludes by proposing that greater coalition building between African religions and Sabbatarian Christians can benefit both historically marginalized groups to attain their full civil and political liberties.
realidade dos deuses e das deusas
Authors: Calvani Carlos Eduardo
Published: September 2023

O título dessa aula é balizado por três palavras-chave: realidade, deuses/as e imaginário. O objetivo é levar estudantes que se iniciam em Ciências da Religião, principalmente graduandos, mas também pós-graduandos oriundos de outras áreas, a compreender um dado simples, mas fundamental: para cada fiel, o seu deus/a é o mais real de todos. São reais no imaginário religioso! Quando faço essa afirmação em sala de aula, invariavelmente alguém comenta: “então, não são reais!”, e eu respondo: “são reais, porque o imaginário religioso é real, assim como todo imaginário é real”. A teoria dos imaginários pode nos ajudar a compreender o universo das linguagens religiosas e o texto oferece informações inicias a quem se interessar pelo assunto. A parte final defende que a palavra realidade deve ser compreendida do modo mais abrangente possível, e não pode ser restrita ao mundo material porque o real comporta o fabuloso, e tudo o que se insere na esfera do sagrado. Em outras palavras, o real permanece real, mesmo que você não admita sua realidade. Alguns setores do mundo acadêmico são muito ingênuos ao julgar-se capaz de convencer ou alterar o imaginário popular a partir de sólidas exposições racionais e argumentos baseados apenas em pesquisas empíricas que nunca saem do círculo das ciências ditas “naturais”. O que chamamos “fatos” ou “razão” são argumentos muito frágeis perante o poder do imaginário. O imaginário, enquanto sistema dinâmico de ideias-imagens de representações coletivas é reflexo do real e, ao mesmo tempo, o outro lado do real, o lado oculto do real.

Rubem Alves (1933-2014) escreveu em 1981 um pequeno livro – O que é religião (Editora Brasiliense). Com esta obra R. Alves conseguiu ampliar sua presença na discussão sobre o fenômeno religioso, alcançando tanto a área acadêmica como um grande público fora das instituições religiosas. A leitura e o estudo desse livro são imprescindíveis para quem pretende dar ao assunto um tratamento científico. Este artigo tem a intenção de oferecer algumas anotações que talvez ajudem a quem se interessa pela análise da religião, segundo a perspectiva de Rubem Alves – como é o caso do GERA Jequitibás (Grupo de Estudos sobre Rubem Alves). Nesse grupo essas anotações serviram de base para conversas muito mais interessantes ainda.
trilha sonora para o fim dos tempos
Authors: Rocha Daniel
Published: September 2023

A banda inglesa Black Sabbath representou um marco na história da música apresentando ao mundo, no início dos anos 1970, uma sonoridade e temáticas líricas sombrias e pesadas, dando origem ao heavy metal. Procuramos analisar, neste texto, a presença de elementos bíblicos, mais especificamente, escatológicos nas canções de seus três primeiros álbuns. Na primeira seção, apresentamos algumas questões teóricas e metodológicas sobre a música como objeto de pesquisa no campo dos estudos de religião. Na sequência, buscamos discutir o contexto histórico e cultural do final dos anos 1960, dentro do qual a obra do Black Sabbath deve ser compreendida. Nas últimas duas seções, nos dedicamos à análise da produção musical da banda no início dos anos 1970. Primeiramente, analisando as características do trabalho levando em conta sonoridade instrumental, performance, letras, contexto histórico e crenças compartilhadas com o público. Por fim, analisamos os elementos bíblicos e escatológicos presentes nas letras de algumas músicas.
Bossa Nova as Existential Turn
Authors: Huff Junior Arnaldo Erico
Published: September 2023

The article approaches Bossa Nova as an experience of resignification at the existentialand religious level, focusing primarily on the song Chega de saudade (No more blues),by Tom Jobim and Vinicius de Moraes. Opinions and testimonies are listed, in orderto attest to the centrality of this song for Bossa Nova and Brazilian Popular Music.Chega de saudade catalyzes aspirations, like a horizon of happiness. The constitutionand main features of the Bossanovista movement are discussed, as well as the albumChega de saudade, by João Gilberto. The musical elements of the song (harmony,rhythm, melody, timbre, interpretation, lyrics, etc.) are treated in their dimension ofmeaning, as an aesthetic-religious experience. Finally, the national and internationalrepercussion of the Bossanovista movement is approached.
Perspectivas científicas sobre experiências religiosas
Authors: Ben Rodrigues Alexandre
Published: September 2023

Este artigo toma o trabalho seminal de William James, As variedades da experiência religiosa (1902) como um ponto de partida de um profícuo debate sobre quais as melhores formas de explicar o fenômeno das experiências religiosas. Há dois pólos na produção científica contemporânea, que podemos chamar de “reducionista” e “não reducionista”. Tanto um como o outro originaram-se sob influência da literatura do século XX, renovando o debate no século XXI à luz de novos indícios empíricos que permitem não só lançar outros olhares sobre a contribuição de James, como também abrir novas perspectivas de análise sobre as experiências religiosas, bem como alternativas para conciliar os dois pólos. Conclui-se que o legado de James pode nos levar a caminhos bastante distintos, o que antes de revelar uma dificuldade de compreensão da sua herança, afirma a multiplicidade de alternativas que dispomos para tentar compreender esse o fenômeno complexo das experiências religiosas.
Religião e invenção cultural
Authors: Schellin de Mattos Thiago
Published: September 2023

A emergência de uma acepção propriamente científica dos fenômenos religiosos esteve desde muito cedo ligada a uma propensão em contrapor a religião à modernidade. Este contraponto, que se realiza diante de um plano de fundo específico, formado pelo cristianismo como referência, sofrerá modificações ao longo do século XX. No entanto, esta tendência será duradoura, a ponto de permanecer influente no desenvolvimento dos estudos de religião até a atualidade. Neste artigo faremos uma breve retomada histórica da construção do conceito de religião nas ciências humanas, com especial enfoque na antropologia. Com as reflexões que se seguem, pretendemos desenvolver alguns apontamentos no nível teórico e metodológico, como condições necessárias para a criação de um conceito de religião como “invenção cultural”.
Recitações Musicais

Published: September 2023

O objetivo do texto é analisar a importância das recitações musicais para a produção do estado religioso entre os discípulos da confraria sufi Hamdouchiya. Os textos utilizados e as formas devocionais existentes forjam os significados convergentes da vida cotidiana dos adeptos. Essas ações devem ser profundamente monitoradas e aperfeiçoadas pelos sujeitos como uma condição necessária para sua eficácia ritual. Compreendo que o processo de recitação musical presente nos locais de culto deve ser analisado como um conjunto de práticas responsáveis pela criação de uma autonomia religiosa aos sujeitos.
Cantando de um Livro - Religião, Música e Letramento
Authors: Ewald Werner
Published: September 2023

Este artigo reflete sobre a tradição literária musical presente na história das comunidades teuto-brasileiras e acionada a partir da “performance” espontânea de um membro desta comunidade, quando entrevistada e solicitada a cantar uma canção. Foca na análise de documentações como hinários sacros, mas também cancioneiros seculares e outras publicações sobre religião, música e letramento, tripé de um projeto de publicações concebido para a comunidade imigrante de fala germânica no Brasil pelo Reverendo Dr. Wilhelm Rotermund e sua pioneira casa publicadora. Como resultado constata-se que tal tripé não é apenas uma produção conceitual teórica, mas, sobretudo, a (re) elaboração de sentidos identitários e de pertencimento social, englobando representações, imaginários e símbolos que organizam múltiplos modos de vida dentro dessa comunidade imigrante no seu passado e na contemporaneidade.
Nature dangereuse et logiques d’alliance dans la Chine archaïque
Authors: Boileau Gilles
Published: September 2023

Cet article, à la frontière entre histoire et anthropologie, est centré sur un dialogue entre quelques données appartenant au domaine de la Chine archaïque et le travail de Roberte Hamayon sur les chamanes sibériens. Deux aspects sont analysés dans ce dialogue. Nous avons abordé la pratique du comparatisme comme usage d’hypothèses en provenance d’un champ de recherche d’un autre domaine, ainsi que les difficultés auxquelles cette pratique expose. Après ce préalable, nous avons cherché à approfondir certaines facettes des rapports entre la société humaine et la nature dans la Chine archaïque. Nous examinons dans la première partie de l’article le chamanisme tel que décrit dans les travaux de Roberte Hamayon, de façon à montrer qu’un manque de référence anthropologique a pu conduire certains spécialistes de la Chine à des conclusions aventureuses. La seconde partie de notre travail, basé en grande partie sur nos recherches antérieures, revient sur le rôle joué par le roi dans les rapports homme-nature. Interviennent dans ces rapports des femmes qui peuvent être considérées comme « monnaie d’échange » entre le souverain et les dieux mâles de la nature. Au cœur de cette relation, la notion d’alliance, à laquelle les recherches de Roberte Hamayon nous ont rendu sensible, constitue un outil de compréhension fondamental dont nous illustrons ici quelques résultats.

En el presente trabajo se propone un nuevo método de síntesis por vía húmeda denominada “Atrano/Hidro- Solvotermal”, que permite obtener nanopartículas de Li 4 Ti5 O12 (LTO) con tamaños predefinidos. Estas nanopartículas se obtienen mediante un control de velocidad de crecimiento de los atrano-clúster metálicos formados durante los procesos de hidrólisis y condensación en solución acuosa y solvotermal. Se sintetizaron nanopartículas de LTO a partir de precursores tipo atrano (litiatrano, titanatrano). Éstos forman complejos de especies oligoméricas “Clústers de Titanio-Oxo-Hidroxo-Atrano” (TOHAC’s). Los TOHAC’s con tamaños predefinidos fueron obtenidos mediante un control del tiempo de hidrólisis y condensación. El tamaño promedio de los TOHAC’s formados se caracterizaron mediante la técnica dispersión dinámica de la luz (DLS), obteniéndose tamaños promedio de 2.40, 7.17, 20.13, y 40.00 nm para las muestras (B:0), (B:48), (B:144) y (B:288) respectivamente. Los TOHAC’s fueron utilizados como bloques de construcción (building blocks), seguidos de un tratamiento Hidro-Solvotermal, y un tratamiento térmico a 500°C. Los difractogramas de DRX de los productos obtenidos muestran la presencia mayoritaria de la fase de interés Li 4Ti5 O12 (LTO) con estructura tipo espinela, y β-Li 2 TiO3 monoclínico como fase secundaria. Las imágenes SEM muestran partículas de diámetro promedio de 12.82 ±5 nm (LTO: B:0) 10.03±3 nm (LTO: B:48), 20.03±7.6 nm (LTO: B:144), y 40.0 ±5 nm (LTO:B:288). Estos tamaños de partícula van en correlación con los TOHAC´s (building blocks) empleados.

Se diseñó un reactor Cilindro-parabólico Compuesto (CPC) en base a un estudio cinético para establecer parámetros para la eliminación de cianuro por fotocatálisis heterogénea, a escala de laboratorio. En la prueba cinética de verificación el valor de k CN obtenido tuvo una variación del 18.52% con respecto al valor estimado por el modelo matemático (kCN =0.0367 min-1 ). Se requirió de una energía acumulada por unidad de volumen de 39.76 kJ/L para eliminar cianuro hasta una concentración equivalente al límite permisible para descargas diarias según el RASIM y el RMCH de la Ley Nº1333 de medio ambiente. Las dimensiones del reactor CPC a escala piloto son: 0.553 m 2 de área total y 20 litros de capacidad de tratamiento. Los colectores solares tienen una dimensión de: 12.29 cm de ancho, 5.26 cm de alto, 1.35 cm de altura de pico y 39.11 mm de diámetro externo de tubo receptor. Se determinó un tiempo de 264.98 minutos para que el sistema pueda reducir las concentraciones de cianuro de 10 mg/L hasta un mínimo de 0.20 mg/L presentes en agua. La temperatura máxima que alcanzó el sistema fue de 26.28 ºC a una radiación UV-A de 49.98 W/m2 , y de 31.55 ºC cuando ésta última fue incrementada a 51.3 W/m 2. Se calculó una eficiencia óptica del 86.36%, la cual favoreció la incidencia de rayos solares UV hasta llegar al seno del líquido en circulación. La potencia necesaria para transportar el fluido a través del sistema fue de 8.20 W (0.011 HP) para asegurar un régimen turbulento pleno.

Se determinó la calidad del agua para consumo humano en los manantiales de la parcialidad de Jiscullaya del distrito de Ilave del departamento de Puno, Perú. La evaluación de calidad química incluyó análisis fisicoquímicos como pH, CaCO3 (dureza total y alcalinidad); Cl - ; SO4-2 ; NO3 ; Ca+2 ; Mg+2 y solidos totales, y el análisis bacteriológico empleando medios de cultivo para los coliformes totales y Eschericha coli. Los parámetros fisicoquímicos encontrados están dentro de los límites máximos permisibles para el consumo humano, sin embargo, el análisis bacteriológico muestra que el agua tiene una contaminación por coliformes. La información brindada por la Posta de Salud Siraya, a la que pertenece la parcialidad de Jiscullaya, reporta que las principales enfermedades en la zona son de origen digestivo como: parasitosis y diarreas. Los resultados del presente estudio sugieren que la causa de dichas afecciones puede ser la mala calidad biológica del agua de la citada parcialidad. Este hecho es un tema de salud pública que las autoridades deben considerar en sus programas de gobierno.

В настоящее когортное исследование было включено 30 пациентов в возрасте от 7 дней до 18 лет с установленным диагнозом «сепсис», которые находились на лечении в отделении реанимации и интенсивной терапии хирургического стационара. Основными патогенами в развитии сепсиса у детей с врожденными пороками развития являлись грамотрицательные микроорганизмы, частота встречаемости грибковой флоры у пациентов с септическим шоком составила 26%. Проведение неадекватной эмпирической антибактериальной терапии чаще обуславливает в дальнейшем развитие септического шока. Эскалационный подход к эмпирической антибактериальной терапии увеличивает частоту развития неблагоприятного исхода. Клинический исход в большей степени был обусловлен выбором стартовой эмпирической антибактериальной терапии.

The purpose of the study to explore the microbial pathogens in the intensive care units, as well as the features of ongoing antimicrobial therapy in order to improve the effectiveness of the treatment of sepsis in children against the background of correction congenital diseases. The cohort study included 30 patients aged 7 days to 18 years with a diagnosis of sepsis, who were treated in the intensive care unit of a surgical hospital. The main pathogens in the development of sepsis in children with congenital diseases were gram- negative microorganisms, the frequency of occurrence of fungal pathogens in patients with septic shock was 26%. Conducting inadequate empirical antibiotic therapy often causes further development of septic shock. An escalation approach to empiric antibiotic therapy increases the incidence of adverse outcomes. The choice of starting empiric antibiotic therapy in many cases determined the outcome.

Введение. Бактериальные поражения центральной нервной системы являются одной из актуальных проблем современной медицины, которые обусловливают необходимость оказания неотложной помощи, интенсивного, в том числе реанимационного, лечения, а также нередко и специализированного хирургического лечения пациентов. Цель. Выявление доминирующих популяций микроорганизмов в этиологической структуре инфекций ЦНС и детекция их антибиотикорезистентных штаммов. Материалы и методы. Исследования проводились в 2019–2022 гг. на кафедре медицинской микробиологии и иммунологии Азербайджанского медицинского университета, откуда и были предоставлены для исследования микроорганизмы, изолированные из патологического материала (ликвор, кровь, выделения из ушных и носовых полостей), взятого от пациентов с подозрением на менингит. Результаты. Наиболее высокую активность против E.coli обнаруживали у гентамицина (70,3; 64,5; 68,2; 69,2% соответственно по годам), нитрофурантоина (60,0; 75,5; 70,1; 70,0% соответственно), а меропенем в 100% случаев во все года исследований показал высокую активность против кишечной палочки. Заключение. Препаратами выбора при лечении инфекций ЦНС, обусловленных E.coli, являются гентамицин, нитрофурантоин, меропенем. При назначении тех или иных химиотерапевтических препаратов рекомендуется проводить постоянный микробиологический мониторинг в клиниках и лабораториях с учетом частоты выявления резистентных штаммов.

Introduction. Bacterial lesions of the central nervous system are one of the urgent problems of modern medicine, which is due to the need to provide emergency care, intensive treatment, including resuscitation, and often also specialized surgical treatment of patients. Purpose. Identification of the dominant populations of microorganisms in the etiological structure of CNS infections and detection of their antibiotic-resistant strains. Materials and methods. The studies were carried out in 2019–2022 at the Department of Medical Microbiology and Immunology of the Azerbaijan Medical University, from which microorganisms isolated from pathological material (cerebrospinal fluid, blood, discharge from the ear and nasal cavities) taken from a patient with suspected meningitis were provided for research. Results. The highest activity against E. coli was found in gentamicin (70.3; 64.5; 68.2; 69.2%, respectively by years), nitrofurantoin (60.0; 75.5; 70.1; 70.0% respectively); and meropenem in 100% of cases in all years of research showed high activity against Escherichia coli. Conclusions. The drugs of choice in the treatment of CNS infections caused by E.coli are gentamicin, nitrofurantoin, meropenem. When prescribing certain chemotherapeutic drugs, it is recommended to conduct constant microbiological monitoring in clinics and laboratories, taking into account the frequency of detection of resistant strains.

This research examined the socio-economic characteristics and profitability of fish marketing participants in the selected fish markets in Lagos and Ogun States. Both descriptive statistics and econometric tools were employed to analyse data collected with structured questionnaire that was administered to 327 respondents in the study area. The significant socioeconomic variables identified are sex, age, household size, access to credit, experience and education. The result of the multiple regression analysis showed that R-square was found to be 0.658 which implies that 65.8percent of the variation in the socioeconomic characteristics affecting the profitability of fish marketing was explained by the independent variables. The result also revealed that the coefficient of fish marketing experience was positively related to profitability at 1% level of significance. This implies that the more the years of experience of the respondent in fish marketing, the more profit they will realize. The coefficient of household size negatively affected the output of fish marketers at 10% level of significance. This implies that the higher the population of the fish marketers’ household size, the lower the profitability of fish marketing. This is because members of the household did eat from the sales stock. The study also revealed that the coefficient of the respondents’ access to credit is positively related to fish profitability at 5% level of significance. This implies that the more the marketers have access to credit, the higher the sales stock with variety of fish. The study showed that high cost of fish, inaccessibility to credit facilities and shortage of supply are most critical constraints facing fish sellers in the study area. The authors suggested that logistics to make cooperative societies to provide adequate credit support to the members should be developed. Individual fish sellers should belong to as many cooperative societies as possible. Government should make fish marketing more attractive to enable more women and youth engage in the business to reduce youth unemployment rate. Locally production of fishes should be encouraged to bridge the supply gap.

Water is one of the most plentiful and essential compound for living organisms and plants all over the world. Millions of people in other parts of the world struggles with problems of water supply during periods of low rainfall and dry season where water supply is extremely low. Rural communities especially in Africa who dwell around seasonal streams rely on sand dams. Sand dams store water in shallow depths along dry stream and river beds, are fetched by scooping out sand. An assessment of existence of sand dams in some communities in the outskirt of Makurdi, Benue State was done. Riverbeds used as viable sand dams were identified; 16 physico-chemical parametres were analyzed to determine the water quality. Turbidity, TC, Fe and Mn, were above the threshold, pH, Cl, Ca, Mg, K, were within the threshold limit and TDS, Nitrate, TH, EC, were within acceptable limits. The overall water quality index was found to be 22.89 which is rated as very poor quality. It is recommended that water from sand dams be treated before it is use for drinking and domestic uses. Sand dams should be constructed using modernized structures to increase water storage which will invariably provide and preserve enough clean water throughout the dry season.

Irish potato is a whether sensitive crop, depends on a regular water supply, to secure high quality yields. Abiotic stress factors, such as drought, heat and salinity, have severe, adverse effects on growth and yield. The production of Irish potato in any part of Nigeria is an integral part of the rural economy, as it is cultivated as a rain-fed and irrigated crop. Timing of both the rain fed and irrigated cultivation is often misplaced, which adversely affect growth and yield in some hot climate areas in some States in Nigeria.The research was experimented with cultivation of Irish potatoes under Makurdi climate in Benue valley - an area believe to be hot, not suitable for cultivating Irish potatoes. The soil of the area was studied, to be sandy clay loam, with a pH of 6.67, which is suitable for the production of Irish Potato. Three 3 varieties of Irish potatoes (Merabel,Nicola and Bertista) were used for the study.25 heads each of the seedlings was planted. Merabel produced the lowest tubers of 86, Nicola 129 tubers and the highest by Bertista with 181tubers. Bertista proved resistant to high temperatures, therefore the most suitable to be cultivated under Benue valley climate at Makurdi.
