    The Amazon has a great biodiversity that needs research to ensure its development without the extinction of its natural resources. This study aims to increase understanding of changes in dynamics (recruitment, growth and mortality) of a natural forest under low impact forest logging over a period of six years

    Elaboração do mapa de riscos do laboratório de pós-colheita, industrialização e qualidade de grãos / Elaboration of the risk map of the post-harvest laboratory, industrialization and grain quality

    O mapa de riscos visa informar de forma ilustrativa aos trabalhadores sobre os riscos do ambiente (físico, químico, biológico, ergonômico e de acidentes) e, desta forma, reduzir a nocividade do local de trabalho.Os círculos, de diferentes tamanhos e cores estão relacionados à intensidade e tipo dos riscos.O objetivo deste trabalho foi elaborar os mapas de risco das salas pertencentes ao Laboratório de Pós-Colheita, Industrialização e Qualidade de Grãos da Universidade Federal de Pelotas.A avaliação dos riscos foi realizada através da observação do local (sala de beneficiamento de arroz, moagem e operações hidrotérmicas, e a sala de análises e aulas práticas) e conversa com os usuários na qual eram definidas probabilidades de ocorrência e gravidade para obter a intensidade. Na sala de beneficiamento de arroz, o ruído, ar sob pressão, postura no posto de trabalho, pouca iluminação e equipamentos sem proteção foram os riscos de maior intensidade. Já sala de análises e aulas praticas nenhum risco foi de grande intensidade, devendo os de intensidade média serem priorizados. Dessa forma, os resultados mostraram os locais e riscos que deveriam ser priorizados no laboratório e, portanto, auxiliaram com informações para tornar o ambiente de trabalho mais salubre

    ADEQUACY OF THE ACCELERATED AGING TEST FOR SOYBEAN SEEDS

    Seed companies use vigor tests in their internal seed quality control procedures. Therefore, it is necessary to choose effective methods to obtain quick responses for making decisions related to the handling, disposal and marketing of seed lots. Thus, the objective of this work was to adapt a methodology for the accelerated aging test in soybean seeds. Sixty-nine lots were used and the experimental design used was completely randomized, with four replications. For the initial characterization of the lots, water content was determined, germination test and field emergence. The soybean seed lots selected based on the initial characterization, were submitted to the standard accelerated aging methodology and twenty-one adapted methodologies. After the physiological characterization of the 69 lots, 24 lots with similar germination with different levels of vigor were selected. For adapted methodologies that used only distilled water inside the gerbox box, there was an increase in the water content of the seeds of all analyzed lots. However, all methodologies with the use of saline solution had a lower water content. The adapted methodologies N (pre-treatment in forced air oven at 35-40ºC for two hours, BOD 42ºC for 24 hours, using saline) and S (pre-treatment in forced air oven at 35-40ºC for two hours, BOD 45ºC for 12 hours, with the use of distilled water) are the most suitable for use in the accelerated aging test for soybean crops, as they present relevant results in a shorter evaluation period.As empresas de sementes utilizam testes de vigor em seus procedimentos internos de controle de qualidade das sementes. Por isso, é necessário escolher métodos eficazes para obter respostas rápidas para a tomada de decisões relacionadas ao manuseio, descarte e comercialização de lotes de sementes. Assim o objetivo deste trabalho foi adaptar uma metodologia para o teste de envelhecimento acelerado em sementes de soja. Foram utilizados sessenta e nove lotes em um delineamento experimental inteiramente casualizado, com quatro repetições. Para a caracterização inicial dos lotes foi realizado a determinação do teor de água, teste de germinação e emergência a campo. Os lotes de sementes de soja selecionados com base na caracterização inicial, foram submetidos a metodologia padrão do envelhecimento acelerado e vinte e uma metodologias adaptadas. Após a caracterização fisiológica dos 69 lotes, foram selecionados 24 lotes com germinação semelhante com diferentes níveis de vigor. Para as metodologias adapatadas e que foram utilizadas apenas água destilada no interiro da caixinha de gerbox, ocorreu um aumento no teor de água das sementes de todos lotes analisados, entretanto,  todas as metodologias com o uso de solução salina, apresentaram um teor de água menor. As metodologias adaptadas N (pré-tratamento em estufa de ar forçado a 35-40ºC por duas horas, BOD 42ºC por 24 horas, com o uso de solução salina) e S (pré-tratamento em estufa de ar forçado a 35-40ºC por duas horas, BOD 45ºC por 12 horas, com o uso de água destilada) são as mais indicadas para o uso no teste de envelhecimento acelerado para a cultura da soja, por apresentarem resultados relevantes em um menor período de avaliação

    An exploratory study of the discourse of the Islam and development: the case of the Islami Bank Bangladesh

    Get PDF
    The relationship between religion and development is a relatively new research area, complicated by the arguably "secular reductionism" and "materialistic determinism" of mainstream development theory and practice. Against this backdrop, this doctoral study examines the relationship between Islamic and mainstream development discourses, analysing the complex power relations at work within the discursive practices of the development field through a conceptual apparatus comprised of a Foucauldian notion of power and discourse and a Laclauan view of hegemony. The objective of this study is to develop a better understanding of how Islamic development policy making and makers have made meaning of the central issues of development and progress as expressed in the body of theory and practice that makes up the development field. Interestingly, Islamic thinkers were already criticising the Euro-centric nature of the development discourse in the 1950s and 60s. They proposed an Islamisation of knowledge, particularly in the field of economics, as a way of overcoming a perceived Western‘ domination. In pursuit of the question as to how "Islam" relates to the issue of development and progress, this thesis explores the genealogy of the mainstream and the Islamic development discourses, illustrated by a selected case study within the development field in Bangladesh

    Concepts of development in Islam: a review of contemporary literature and practice

    Get PDF
    This article explores whether and the extent to which the Islamic tradition espouses particular development models. Specifically the purpose of this paper is to provide an overview of recent materials produced by relevant Islamic institutions and by some of the main academic interpreters, in order to assist in the development of a basic conceptual understanding of the factors that may influence particular Islamic approaches to development issues encountered in the field. As background, first some trends in the study of Islam are identified, and then a brief history of Islamic civilization is sketched. The paper then moves to explain the basic tenets of the Muslim face, followed by a description of the main Islamic sects. The article finally moves to an exploration of some key pan-Islamic organizations, and their role in development
