Authors: Contreras Santos José Luis , Espinosa Carvajal Manuel Ramón , Cadena Torres Jorge , Martínez Atencia Judith , Falla Guzmán Cindy Katherine , Garrido Pineda Jeyson Fernando 
Published: January 2022

Introducción. El óxido nitroso es un gas de efecto invernadero de gran impacto sobre el calentamiento global. En los sistemas de producción ganaderos es de gran importancia buscar alternativas que permitan mitigar las emisiones de N2O, dentro de las cuales se ha considerado el uso de coberturas vegetales capaces de reducir el proceso de nitrificación. Objetivo. Evaluar la dinámica de los flujos de N2O en suelos bajo ocupación ganadera cubiertos con gramíneas mejoradas y fertilización nitrogenada (Úrea). Materiales y métodos. Esta investigación se desarrolló en un sistema de producción de carne en el valle medio del Rio Sinú, en el cual los flujos de N2O fueron monitoreados durante un periodo de 12 meses (noviembre 2014 - 2015). Se utilizó un diseño experimental de bloques completos al azar, en arreglo de parcelas divididas y 2 repeticiones, en donde la parcela principal correspondió a las gramíneas (Brachiaria humidicola CIAT679 y Panicum maximum cv. Tanzania) y suelo descubierto, y las subparcelas a 3 dosis de fertilización nitrogenada (0, 150, 300 kg.ha-1.año-1 N). Resultados. Los flujos de N2O fluctuaron según el contenido de humedad del suelo, asociado a los periodos de mayor o menor precipitación en la región. La cobertura con la gramínea Brachiaria humidicola cv CIAT679 mostró menores emisiones de N2O, mientras que las dosis de fertilizantes nitrogenados aumentaron las emisiones de N2O. Dichos efectos fueron en parte atenuados por el uso de la cobertura con Brachiaria humidicola CIAT679. Conclusiones. Los resultados obtenidos indican que las emisiones de óxido nitroso en los sistemas ganaderos podrían variar a partir del tipo de cobertura y las dosis de fertilización nitrogenada utilizadas. En este caso, se encontró que la cobertura con Brachiaria humidicola cv CIAT679 en los sistemas de producción ganaderos reduce en más del 40%las emisiones de óxido nitroso hasta una dosis de N máxima de 300 kg.ha-1.año-1

A comunidade educativa e o trabalho com valores sociomorais: dois estudos de caso - uma Escola Cooperativa e uma Rede Municipal
Authors: Ferreira Marilucia Moraes de Paula , Aragão Ana Maria Falcão de 
Published: January 2022

Neste trabalho, o olhar para a Educação se dá tendo por base a convivência ética e democrática nas escolas e a educação de valores sociomorais, os conflitos interpessoais como oportunidade de aprendizagem e a gestão cooperativa como mediadora em prol do desenvolvimento moral da comunidade educativa. Para investigar como a escola legitima as ações e as decisões coletivas, já previstas em uma gestão democrática, visando ao bem comum, é importante destacar que foram realizados dois estudos de caso. O primeiro foi efetuado a partir de um projeto de formação em uma escola cooperativa e o outro, em uma rede municipal. Destacamos que o primeiro foi demandado por meio do seguinte relato: “A escola apresenta algumas situações preocupantes: 1. Equipe de profissionais e os membros da mantenedora estão divididos em dois grupos, percebendo-se uma ruptura, pensamentos divergentes que levam a mal-entendidos e procedimentos inadequados, como consequência da falta de um elo para direcionar as decisões. 2. Não há cooperação do grupo, em virtude da falta de harmonia conceitual, pois a escola possui uma gestão democrática. Enfim, torna-se necessário ter o apoio de um profissional externo para alinhar ações, a fim de que a escola caminhe com segurança, para se resgatar a cultura participativa”. No segundo projeto, a necessidade detectada foi identificar os princípios democráticos da escola, para sustentar a elaboração do Projeto de Convivência Ética de uma rede pública municipal, cujo objetivo foi revelar os procedimentos de que o gestor dispõe, a fim de se chegar a um projeto de escola que seja político, isto é, participativo e dialógico, por meio do Projeto Convivência Ética. Antes de desenvolver um trabalho é necessário alinhar os aspectos procedimentais previstos nos documentos da instituição, sendo essencial superar o modus operandi da escola, sedimentado já há muitos anos, problematizando o entendimento do conceito de valor. Já na rede pública municipal, o objetivo foi promover a discussão acerca do Plano de Convivência Ética nas escolas aliado ao seu Projeto Político-Pedagógico. Os valores, os princípios e as regras eram discutidos, para que se estabelecesse uma relação com os projetos das escolas, de sorte a instrumentalizar a gestão na direção de um fazer democrático. Finaliza-se, apontando que o intuito das autoras é apresentar evidências de que só é possível que os sujeitos validem e legitimem os projetos e as ações na escola, se vivenciarem os conceitos em questão.
Relações de gênero e religião: análise das práticas religiosas da Santeria em Cuba
Authors: Braffo Conde Naile 
Published: January 2022

Na contemporaneidade as sociedades se caracterizam por transformações políticas, econômicas e culturais que influenciam subjetividades e relações sociais, como é o caso das relações de gênero. A religião, como parte integrante do sistema social, estabelece conexões dentro das suas estruturas, seja na construção de representações sociais, na legitimação ou na dissimulação de jogos de poder. Por assim dizer, a análise da relação entre gênero e religião em qualquer sistema religioso constitui um desafio. O presente artigo busca analisar – ou pelo menos tenta discutir –, essa relação no sistema religioso Regla de Ocha ou Santeria em Cuba. Portanto, sem a necessidade de hipótese, apresentam-se ideias que contribuem para pensar essa relação.
Direitos reprodutivos em debate: a retórica de parlamentares evangélicos/as na 54ª Legislatura para a criminalização do aborto
Authors: Costa Emerson Roberto da 
Published: January 2022

O recrudescimento de intervenções baseadas na moral religiosa contra a promulgação de leis tais como a regulamentação do aborto, da criminalização da homofobia e do casamento igualitário, tanto suscita o questionamento acerca dos limites da laicidade no Brasil, quanto do processo de secularização e da fidelidade aos preceitos religiosos, bem como impedem ações - inclusive aquelas de caráter educativo – que reconheçam e favoreçam a pluralidade e a diversidade. Não se trata de construir uma cronologia da legislação sobre o aborto no parlamento, nem discutir a pertinência ética da despenalização, mas identificar a influência do discurso religioso sobre a consolidação de direitos na contemporaneidade.
Clustering Framework to Cope with COVID-19 for Cities in Turkey
Authors: Guleryuz Didem , Ozden Erdemalp 
Published: January 2022

Introduction: This article is the product of the research “Clustering Framework to Cope with COVID-19 for Cities in Turkey”, developed at Bayburt University in 2021.
Problem: Turkey's risk map, presented in January 2021, to take local decisions in tackling the COVID-19 pandemic was based on confirmed cases only. Health, socio-economic and environmental indicators are also important for management decisions of COVID-19. The risk map to be designed by adding these indicators will support more effective decisions.
Objective: The research aims to propose a clustering scheme to design a risk map of cities for Turkey.
Methodology: The unsupervised clustering algorithm suggested dividing the cities of Turkey into clusters, considering health, socio-economic, environmental indicators, and the spread pattern of COVID-19.
Results: We found that cities are clustered into five groups while megacity Istanbul alone formed a cluster, three of Turkey's largest cities formed another cluster. Other clusters consist of 19, 26, and 32 cities, respectively. The most important determinants which have predictive power are identified.
Conclusion: The suggested clustering method can be a decision support system for policymakers to determine the differences and similarities of cities in quarantine decisions and normalization phases for the following periods of the pandemic.
Originality: To the best of our knowledge, this study differs from previous studies because countries were grouped in previous studies only considering the confirmed cases. In this study, cities were clustered in terms of the health, socio-economic, and environmental indicators to make decisions locally.
Limitations: The distribution of confirmed cases by age could be added, especially to make decisions about education, but this data is not officially announced.
Differentiation in seed mass and seedling biomass allocation in Prosopis laevigata throughout its distribution range in Mexico is associated to water availability
Authors: Hernández-Madrigal Fátima , Contreras-Negrete Gonzalo , Aguilar-Romero Rafael , Pineda-García Fernando , González-Rodríguez Antonio 
Published: January 2022

Background: Seedling establishment depends on the quality of the seeds and environmental conditions. Differential biomass allocation in emergent seedlings probably constitutes a relevant adaptive response of populations along environmental gradients.
Questions: Are there differences in seed mass and biomass allocation in seedlings among Prosopis laevigata populations? Is this variation correlated with environmental variables?
Studied species: Prosopis laevigata (Humb. & Bonpl. ex Willd.) M.C.Johnst (Fabaceae).
Study site and dates: Thirteen localities along the distribution of P. laevigata in México. From 2016 to 2020.
Methods: Seeds were collected from four or five mother trees per locality. Seed mass (SM) was obtained in ten seeds per mother and six functional traits indicative of biomass allocation were measured in the seedlings after 10 days of germination. Population mean values were obtained for the six traits plus SM and subjected to a principal component analysis (PCA). Population scores on the first two axis of the PCA were regressed against environmental variables from the collection localities using a stepwise regression model.
Results: Populations displayed functional variation congruent with alternative biomass allocation strategies. The conservative strategy was characterized by larger seeds and seedlings with denser tissues and a higher investment in root biomass, while the opposite characterized the acquisitive strategy. Actual evapotranspiration in May, isothermality and soil water content in February were environmental variables that significantly predicted population scores on the first two axes of the PCA.
Conclusion: Water availability gradients influence seed mass and seedling biomass allocation variation among P. laevigata populations.
Red cell alloimunization and autoantibodies in transfusion dependent thalassemia patients of Jammu region
Authors: Dutt Neeti , Sharma Sushil , Sidhu Meena 
Published: January 2022

Background: Thalassemia is one of the most common genetic disorder of hemoglobin synthesis in Jammu region. Although RBC transfusion is life saving for these patients, it may be associated with some complications like RBC alloimmunization. Thus, alloimmunization against red blood cell antigens increases the need for transfusion and can significantly complicate transfusion therapy. Therefore, screening for unexpected antibodies should be a part of all pretransfusion testing, with antibody identification in the event of a positive result. The aim of the study was to determine the frequency of alloimmunization and autoimmunization and the most common alloantibodies involved.Methods:This was a descriptive study involving a total of 146 thalassemic patients in the age range of 2-32 years receiving regular blood transfusions, registered at SMGS blood bank, Jammu. Antibodies screening, antibody identification, and cross matching was done on all patient samples included in the study, during the period between November 2014 and October 2015.Results: At the start of the study, 8 patients who tested positive for alloantibodies 3 patients had more than one antibody subtype. Anti-E was the commonest antibody found in 4 (50%) patients. Similarly, at the end of study, antibody screening and then identification revealed presence of antibodies in 10 patients. Only 1 patient had more than one antibody subtype. Anti E was again the commonest antibody found in 5 (50%) patients. Conclusions:The most common alloantibodies identified were anti Rh system antibodies (anti-E and anti-D) followed by Kell antibodies. In order to reduce alloimmunization, a policy for performing extended red cell phenotyping of these patients is essential and at least antigen E and Kell negative blood should be provided for transfusion to these patients.

Published: January 2022

Background: Serum C-peptide has appeared as the chief clinical and practically adequate marker of β-cell function of pancreas. Serum insulin and C-peptide are concomitantly secreted into the blood circulation in equal amount. The aim of the study was to determine serum C-peptide levels in newly diagnosed diabetic mellitus subjects of North Gujarat region of India.Methods:The present cross-sectional study was done on 50 subjects of recently diagnosed Diabetes mellitus (T2DM) and non-diabetic healthy controls at Banas Medical College and our trust-based hospital. All diabetics patients were further classified into two groups; normal FC group consist of subjects with FC level 0.5-3.2 ng/ml (N=14) and high FC group included subjects with FC>3.2 ng/ml (N=36). The patients' demographic and anthropometric parameters were recorded; detailed history and clinical examination were performed in the entire cases. All biochemical parameters were analyzed. Results: Predominance of the T2DM subjects was in the age group of 41-50 years. Mean value for age (p<0.01), anthropometric (p<0.01), fasting plasma glucose (p<0.001), HbA1c (p<0.01), cholesterol (p<0.01), triglycerides (p<0.001) and C-peptide (p<0.001) were significantly higher in the T2DM subjects. The mean values of fasting plasma glucose (p<0.001) and HbA1c (p<0.01) are significantly higher in T2DM subject with high C-peptide level as compared to normal C-peptide level. Conclusions:In our study, we conclude that elevated levels of fasting C-peptide in newly diagnosed T2DM. Therefore, we suggested that serum C-peptide levels are valuable as marker of endogenous insulin production from β-cell of pancreas.
Rare as hen’s teeth: laparoscopic management of primary pelvic hydatid cyst
Authors: Gupta Kopal , Sharma Dron 
Published: January 2022

Hydatid disease is a zoonotic parasitic disease most frequently caused by echinococcus granulose Primary peritoneal hydatidosis is very rare. We report a case of primary hydatid disease of the intraperitoneal pelvic space. A 22-year-old male patient presented with a history of abdominal pain since 5 months. Abdominal examination revealed a smooth, firm, mildly tender, non-mobile lump in suprapubic region, on digital rectal examination, a smooth spherical mass was felt anteriorly and laterally outside the rectal wall, rectal mucosa was normal. All routine investigations including liver function tests were within normal limits Computed tomography scan of the whole abdomen showed giant cyst of 10×10 cm with multiple well-defined cysts in rectovesical pouch. Diagnostic laparoscopy was performed. The liver, spleen, mesentery, omentum was found to be normal. A large tense hydatid cyst was noted in the pelvic cavity. Partial peri-cystectomy with endo-cystectomy was performed. Postoperative period was uneventful and patient was discharged on 4th postoperative day. Primary intra-abdominal but extra-peritoneal localization has been reported in only 0.2-2% cases making it a very rare entity. The treatment of choice for pelvic hydatid cyst is principally a careful surgical excision. Here with minimum invasive technique this case was operated and results were excellent.

Authors: Rakytska Svitlana , Kambur Olga 
Published: January 2022

The COVID-19 pandemic has influenced all dimensions of human living, including, exponentially, the road transport situation in large cities. The factors of influence are subjective or objective, and have an multidirectional impact on the degree of traffic congestion, travel time to the destination and the situation of the environment. The characterization of the cumulative influence of these factors involves the use of statistical, analytical methods and models to parallel the situation “before” and “after,” as well as predict its development in the future.
Predicated on the information of traffic congestion, it was exposed how the quarantine severity influenced the traffic intensity, particularly the largest cities in Ukraine: Kyiv, Odesa, Kharkiv, Dnipro. The influence of the time factor on the road situation is analyzed, and an assessment is made of how traffic flows are redistributed in accordance with the new conditions.
The directions for improving transport accessibility and urban mobility in the context of the epidemic are proven: digital transformation, spreading the network of bike paths, organization of convenient pedestrian paths, nano-districts and micro-districts where everything needed is nearby.
