Guillermo Cabrera Infante and the variables of power in the religious sphere of La Habana of the fifties

En una trilogía de relatos cortos titulada Delito por bailar el chachachá (1995), el escritor cubano Guillermo Cabrera Infante evoca una vez más, desde su largo exilio, a La Habana de los 50. Su intensión narrativa se desplaza más allá de los conflictos entre personajes, para regodearse en una espléndida descripción del estado cultural y social de la ciudad en que transcurren sus historias. La Habana es vista a través de su geografía, sus costumbres, sus mitos, sus creencias y su sistema de reglas y prohibiciones. Lo esencial en estas narraciones no es, por tanto, lo que intentan relatar, sino lo que rememoran, recuperan y, hasta revelan, de esa capital que lentamente desaparece. El presente artículo examina solo uno de los cuentos que componen esta trilogía: "El gran Ecbó", donde los aspectos anteriores son claramente palpables, y donde se puede ahondar en las intrincadas redes sincréticas que sustentan la cultura insular. Paralelamente al interés temático del autor, este trabajo destaca el valioso uso de técnicas literarias contemporáneas, con las que Cabrera Infante construye una ciudad en plena transformación, en la que la modernidad, con todas sus energías, no puede borrar las fuerzas del pasado.In a trilogy of short stories titled Delito por bailar el chas cha cha (1995), the Cuban writer Guillermo Cabrera Infante evokes once again, from his lengthy exile, La Habana de los 50. His narrative intention goes beyond the conflicts between characters, in order to wallow in a splendid description of the cultural and social status of the city in which his stories elapse. La Habana is seen through his geography, customs, myths, beliefs and system of rules and prohibitions. The essential point of these narratives is not so much what they intend to convey, but rather what they recall, recover and even reveal of that city that is slowly disappearing. The present article examines only one of the stories that encompasses this trilogy; "El gran Ecbó", where the previous aspects are clearly palpable, and where you can delve into the intricate networks that support the syncretic island culture. Parallel to the thematic focus of the author, this work highlights the valuable use of contemporary literary techniques with which Cabrera Infante builds a city undergoing transformation, in which modernity, with all his energy, can not erase the forces of the past.Fil: Verson, Lidia.

Plantas de cobertura de ver?o em cultivo solteiro no fornecimento de nitrog?nio para o milho safrinha

In the southern region of Brazil, the most utilized agricultural model is the no-tillage system of planting, with the usage of cover crops, mostly in winter, which is scarcely used during summer. The usage of cover crops is normally delineated as mere tool to diminish the growth and establishment of spontaneous plants, not being taken in account the recycle or nutrients fixation potential of these crops. The following study aimed to evaluate the usage of cover plants on summer single crops, for nitrogen supply on serafin maize. The search was conducted during the agricultural years 2017/2018 in Cerro Largo-RS, at Latossolo Vermelho. In a randomized block design, with plots (10 X 3,5 m) with 4 replicates, were established with cover crops and posterior subdivided in a subgroup culture, the maize, with or without nitrogen fertilization. Five cover crops were evaluated, millet (Pennisetum glaucum L), sudan grass (Sorghum bicolor cv. sudanense), crotalaria juncea (Crotalaria juncea L), jack beans (Canavalia ensiformes) and land set-aside of single crops. The evaluation of dry matter yield assessments of the area (DMYA), cumulated nitrogen quantity (N), decomposing and liberation of N from DMYA of cover crops were developed. During the cultivation of maize were evaluated the mineral N content in the soil, the grain yield and weight of a thousand grains (WTG). The millet produced the greater quantity of DMYA and accumulated an N quantity similar to the jack beans, despite this legume had produced 52% of DMYA of the gramineae. The jack beans, millet and crotalaria crops increased the maize productivity in comparison to the land set-aside and to the sudan grass when not utilized the mineral N. Even with N supplement for the maize, the cover crops increased the grain productivity, particularly with the usage of jack beans and millet.Na regi?o sul do Brasil o modelo agr?cola mais utilizado ? o sistema de plantio direto, com o uso de plantas de coberturas, principalmente no inverno, sendo muito pouco difundido o uso de plantas de cobertura de ver?o. A utiliza??o das plantas de cobertura geralmente ? retrato apenas como um meio de diminuir o aparecimento e estabelecimento de plantas espont?neas, n?o levando em considera??o o potencial de reciclagem ou fixa??o de nutrientes pelas plantas O presente estudo tem como objetivo avaliar o uso de plantas de cobertura de ver?o em cultivo solteiro, no fornecimento de nitrog?nio para o milho safrinha. O trabalho foi conduzido nos ano agr?cola de 2017/2018 em Cerro Largo-RS, em Latossolo Vermelho, em delineamento de blocos ao acaso, com parcelas principais (10 X 3,5 m) com 4 repeti??es, foram estabelecidas plantas de cobertura e posterior subdivididas na cultura subsequente, o milho, com e sem a utiliza??o de aduba??o nitrogenada. Foram avaliados cinco plantas de cobertura, milheto (Pennisetum glaucum L), capim sud?o (Sorghum bicolor cv. sudanense), crotal?ria juncea (Crotalaria juncea L), feij?o de porco (Canavalia ensiformes) e pousio em cultivo solteiro. Foram realizadas as avalia??es de rendimento de mat?ria seca da parte ?rea (MSPA), quantidade de nitrog?nio (N) acumulado, decomposi??o e libera??o de N da MSPA das plantas de cobertura. Durante o cultivo do milho foram avaliados os teores de N mineral no solo, rendimento de gr?os e peso de mil gr?os (PMG). O milheto produziu a maior quantidade de MSPA e acumulou quantidade de N semelhante ao feij?o de porco, apesar da leguminosa ter produzido 52 % da MSPA da gram?nea. As culturas de feij?o de porco, milheto e crotal?ria incrementaram a produtividade de milho em rela??o ao pousio e ao capim sud?o quando n?o foi utilizado N mineral. Mesmo com suprimento mineral de N para o milho, as plantas de cobertura incrementaram o rendimento de gr?os, principalmente com o uso de feij?o de porco e milheto

Análise da viabilidade da implementação de barcaças jumbo no tramo norte da hidrovia do Rio Paraguai – Passo Corixão

Orientador : Gustavo Pacheco TomasMonografia (graduação) - Universidade Federal do Paraná, Setor Reitoria, Curso de Graduação em Engenharia CivilInclui referênciasO Brasil possui uma grande extensão de rios navegáveis e que devem ser integrados a atual expansão do comércio portuário. O governo brasileiro tem investido em análises, como o Estudo de Viabilidade Técnica, Econômica e Ambiental (EVTEA) da hidrovia do Rio Paraguai, que indicam um aumento da viabilidade no caso de ampliação do porte do comboio de navegação. Este estudo contempla a análise de viabilidade da implantação de barcaças do tipo jumbo, com dimensões superiores as atuais utilizadas na hidrovia. Para exemplificar esta adequação foi realizado um novo dimensionamento do canal de navegação para o Passo Corixão, local de passagem crítica do tramo norte na hidrovia do rio Paraguai. O dimensionamento utilizou a metodologia da PIANC (2014), resultando em um acréscimo de 33% de largura do canal atual de 45m. O calado considerado foi o mesmo atualmente utilizado na hidrovia, com 1,8m de profundidade. Após calcular o volume de dragagem e fazer uma análise comparativa com os dados obtidos pelo EVTEA, nota-se um acréscimo de 23,21% do volume a ser dragado. Ao avaliar as alterações necessárias em conjunto com os custos de transporte, conclui-se que o aumento do volume transportado proporcionado barcaças do tipo jumbo, aumentam a viabilidade da via, pagando os custos de dragagem em número pequenos de viagens no ano

Resourcing Scholar-Activism: Collaboration, Transformation, and the Production of Knowledge

We begin by suggesting that research questions should be triangulated to consider not only their scholarly merit but the intellectual and political projects the findings will advance and the research questions of interest to community and social movement collaborators

Case report: A familial B-acute lymphoblastic leukemia associated with a new germline pathogenic variant in PAX5. The first report in Mexico

B-cell acute lymphoblastic leukemia (B-ALL) is one of the most common childhood cancers worldwide. Although most cases are sporadic, some familial forms, inherited as autosomal dominant traits with incomplete penetrance, have been described over the last few years. Germline pathogenic variants in transcription factors such as PAX5, IKZF1, and ETV6 have been identified as causal in familial forms. The proband was a 7-year-old Mexican girl diagnosed with high-risk B-ALL at five years and 11 months of age. Family history showed that the proband’s mother had high-risk B-ALL at 16 months of age. She received chemotherapy and was discharged at nine years of age without any evidence of recurrence of leukemia. The proband’s father was outside the family nucleus, but no history of leukemia or cancer was present up to the last contact with the mother. We performed exome sequencing on the proband and the proband’s mother and identified the PAX5 variant NM_016734.3:c.963del: p.(Ala322LeufsTer11), located in the transactivation domain of the PAX5 protein. The variant was classified as probably pathogenic according to the ACMG criteria. To the best of our knowledge, this is the first Mexican family with an inherited increased risk of childhood B-ALL caused by a novel germline pathogenic variant of PAX5. Identifying individuals with a hereditary predisposition to cancer is essential for modern oncological practice. Individuals at high risk of leukemia would benefit from hematopoietic stem cell transplantation, but family members carrying the pathogenic variant should be excluded as hematopoietic stem cell donors
