Organomineral Phosphorus Fertilization in the Production of Corn, Soybean and Bean Cultivated in Succession  [PDF]
Denize Carvalho Martins, álvaro Vilela De Resende, Jo?o Carlos Cardoso Galv?o, Eduardo De Paula Sim?o, José Paulo Da Costa Ferreira, Gabriela De Oliveira Almeida
American Journal of Plant Sciences (AJPS) , 2017, DOI: 10.4236/ajps.2017.810163
Abstract: The use of organic waste in agriculture has been used aiming at greater productivity, decrease in the cost of production and sustainable use of resources. The present study aimed at evaluating the effect of phosphate fertilization with the maintenance of organomineral fertilizers, combining poultry manure and soluble or reactive phosphate, in the production of grains in corn culture and the residual effect for subsequent crops of beans and soybeans. The experiment was conducted in Sete Lagoas, MG, in 2015, using three fertilizers with sources of different phosphorus sources (triple super phosphate—STP, organomineral with STP and organomineral with Bayovar phosphate) applied at the doses of 65, 130, 195 and 260 kg·ha¯1 of P2O5 total, and compared to the control without phosphate fertilization. We evaluated the contents of foliar P, P accumulation in the grains, yields of corn grains, beans and soy, accumulated productivity and export of accumulated P of the three cultures. The three cultures assessed presented higher productivity when compared to the average of the factorial treatments that received phosphate fertilization relative to the control. Organomineral fertilizers increased grain production, obtaining average productivity equal to or greater than those obtained with the exclusive use of STP.

Abstract: Determination of seed physiological maturity and ideal moment for harvesting fruits to extract their seeds are important aspects to produce seeds with high quality. To identify the best period for harvesting eggplant fruits, associated with ideal resting period of the fruit for extracting seeds, an eggplant production field was installed in municipality of Ijaci, in the State of Minas Gerais, Southwestern Brazil. The fruits were harvested at periods of 49, 56, 63, 70, and 77 days after pollination (DAP). The seeds of fruits harvested in each period were manually extracted immediately after harvest or after a post-harvest resting period of seven days, under a shed. The physiological quality of seeds was assessed by tests of: germination percentage; germination and emergence speed indexes; and electrical conductivity; which were carried out in the Central Seed Laboratory, Federal University of Lavras. Electrophoretic analyses of isoenzymes: catalase (CAT); esterase (EST); superoxide dismutase (SOD); and peroxidase (PO), were also therein performed. Results of germination and vigor of seeds have showed that the best period for harvesting the fruit is around 70 DAP; and that seeds should be extracted immediately after harvest. Electrophoretic analysis of enzymes has showed immaturity for eggplant seeds, harvested after 49 DAP. A determina o da maturidade fisiológica das sementes e do momento ideal de colheita dos frutos para extraí-las s o aspectos importantes para a produ o de sementes com alta qualidade. Para identificar a melhor época de colheita dos frutos de berinjela e o tempo ideal de descanso do fruto para extra o das sementes, foi instalado um campo de produ o, no município de Ijaci, MG. Os frutos foram colhidos aos 49, 56, 63, 70 e 77 dias após a poliniza o (DAP). As sementes dos frutos colhidos, em cada época, foram extraídas manualmente, imediatamente após a colheita, ou ent o após repouso pós-colheita, por sete dias, em galp o. A qualidade das sementes foi avaliada por meio dos testes de: germina o; emergência; índices de velocidade de germina o e emergência; e condutividade elétrica; e também a análise eletroforética das isoenzimas catalase (CAT), esterase (EST), superóxido dismutase (SOD) e peroxidase (PO) foram conduzidas no Laboratório Central de Sementes, Universidade Federal de Lavras. Os resultados de germina o e vigor das sementes revelaram que a melhor época para a colheita dos frutos é de, aproximadamente, 70 DAP; e que as sementes devem ser extraídas imediatamente após a colheita. A análise eletroforética das enzimas evidenci
Reuso de efluentes em torres de resfriamento - estudo conceitual: Aeroporto Internacional do Rio de Janeiro = Water reuse for cooling towers – conceptual study: Rio de Janeiro International Airport

Abstract: O reuso de água é ferramenta valiosa na gest o da água, que promove a otimiza o da utiliza o do recurso desta, que reduz e, muitas vezes, até elimina os impactos no meio ambiente. Neste trabalho foi investigada a composi o do efluente secundário da esta o de tratamento de efluentes (ETE APOIO) do Aeroporto Internacional do Rio de Janeiro, com o objetivo de propor o processo adequado à reutiliza o deste efluente como água de reposi o nas torres de resfriamento desse Aeroporto. Com base nas análises de cátions, anions, DBO e DQO, verificou-se o parametro SDT - Cl- como crítico para processamento do efluente. Foi proposta uma sequência para reutiliza o do efluente que continha o tratamento de osmose inversa, o custo do m3 produzido por essa sequência foi estimado em R$ 2,90 m-3. Water reuse is an important tool in water management; it is a conceptthat promotes optimization of the water resource, reducing and often even eliminating environmental impacts. In this work, the composition of a secondary effluent (from the effluent treatment station (ETE APOIO) at Rio de Janeiro International Airport) was analyzed, with theaim of determining an adequate process for the reutilization of this effluent as replacement cooling water. Chemical analyses such as cation and anion analysis, BOD and COD were performed. Based on these analyses, it was found that TDS - Cl- was the critical parameter foreffluent processing. A treatment system was proposed for effluent reuse including reverse osmosis; the cost estimate per m3 produced by this system was R$ 2.90 m-3.

Abuso Sexual e Resiliência: Enfrentando as Adversidades
Rosimeire de Carvalho Martins
Revista Mal-estar e Subjetividade , 2011,
Abstract: El estupro, un tipo de abuso sexual es un delito universal, ilegal y reportado, practicado contra la libertad sexual de una persona. Puede ser definido como un acto de fuerza en que la persona agresora obliga otra a mantener relación sexual contra su voluntad. Las víctimas preferenciales con frecuencia son del sexo feminino, aun cuando ni as yadolescentes. Es considerado un problema de salud pública debido a su elevada incidencia y a las graves consecuencias para la salud. Este estudio ha investigado la percepción de jóvenes mujeres victimadas sexualmente sobre las consecuencias que la violencia ha traído a su salud con relación a los aspectos emocional, físico y comportamental, así como las estrategias de superación de los agravios oriundos de la violencia y que indicadores ellas han usado para afirmar que han superado los efectos aciagos a su salud. Fueron entrevistadas dieciocho mujeres, siendo doce víctimas de abuso extrafamiliar y ses de abuso intrafamiliar. Los datos han sido analisados a través de la utilización de la técnica de análisis de contenido temático. Hemos verificado que para las mujeres del grupo extrafamiliar los efectos negativos de la ocurrencia en la salud permanecian, aun después del pasaje de un a o del suceso, dificultando sus relaciones sexuales, sociales y familiares. Ellas no han contado com el apoyo de familiares y de profesionales. En las mujeres del grupo intrafamiliar, hemos identificado una creciente mobilización para superar el estrés y sus consecuencias nocivas de la ocurrencia y reanudar a la vida. El apoyo familiar y social han actuado como facilitadores en el desarrollo de comportamientos resilientes y en el enfrentamiento de los efectos adversos de La violencia sufrida.

Abstract: O presente artigo visa refletir sobre a pertinência da utiliza o das teorias do risco social para a garantia dos direitos e prote o social. Deste modo, realiza uma reflex o sobre a importancia e os limites dos direitos nas sociedades burguesas, em um contexto onde os recursos do fundo público destinados às políticas sociais passam a ser cada vez mais solicitados pelo ca-pital. Este processo vem associado à divulga o de uma ideologia individualista e contrária aos direitos, associando sua concep o ao enfrentamento pontual da pobreza, voltado para os segmentos ditos em condi o de risco. O texto finaliza refletindo sobre impertinência da utiliza o deste conceito para a prote o social, resgatando a importancia de se valorizar interven es amplas, de promo o e desenvolvimento, comprometidas com a efetiva o dos direitos e a emancipa o humana

Abstract: in impoverished segments of the society, the increase in the incidence of obesity raises a question concerned with its etiology. the objective of this paper is to characterize the prevalences of overweight and obesity in these populations. three hundred and ninety families joined the program, including 782 individuals with ages above 19 years, 360 (46,0%) of them were men and 422 (54,0%) were women. the prevalences of obesity among men from urban and rural areas were 5.6% and 5.8%, respectively. concerning overweight, this incidence was about 25% for both regions, and the percentages increased with age. the prevalences of obesity among men and women were, respectively, 5.6% and 21.6% (p<0,05). among women the ocurrence of obesity increased slightly with age, and the prevalences were 19.8% in urban areas and 23.4% in rural areas. therefore, as the evaluated population lives in extreme poverty, the excess of weight, which hits mainly the women, has a complex etiology and needs to be better studied.
