| ABSTRACT Grassland and savanna ecosystems are the original vegetation types of more than 30% of the Brazilian territory, but conservation and training of future professionals has largely focused on forests. In fact, no standard protocols exist for sampling grassland vegetation for environmental planning or licensing. Neglecting non-forest ecosystems may have deleterious consequences for the maintenance of biodiversity and the provisioning of ecosystem services. Herein, we provide practical guidelines on how to conceive and develop ecological studies of grassland vegetation for scientific, monitoring or technical purposes. Using examples mostly from southern Brazil, we explain and discuss the various components of the research process, from the question to... |

| ABSTRACT Soybeans contain about 30% carbohydrate, mainly consisting of non-starch polysaccharides (NSP) and oligosaccharides. NSP are not hydrolyzed in the gastrointestinal tract of monogastric animals. These NSP negatively affect the development of these animals, especially the soluble fraction. This work aimed to establish a method to quantify NSP in soybeans, using high performance liquid chromatography (HPLC), and to estimate correlations between NSP, oligosaccharides, protein and oil. Sucrose, raffinose + stachyose, soluble and insoluble NSP contents were determined by HPLC. Oil and protein contents were determined by near-infrared spectroscopy (NIRS). The soluble PNAs content showed no significant correlation with protein, oil, sucrose and raffinose... |

| Estima-se que, em menos de 40 anos, duplique a populacao brasileira. Isso equivale dizer que, se nao houver apreciavel aumento de eficiencia e de produtividade na agricultura, sera preciso duplicar a area de cultivo. Na verdade o problema ja existe: a populacao brasileira e mal-nutrida, ha carencia de alimentos e os precos dos produtos alimenticios tendem a aumentar em razao de uma relativa ineficiencia nas atividades agricolas. Tanto para aumentar a eficiencia e a produtividade da agricultura, como para duplicar a area de cultivo, dois fatores sao importantes: terra e tempo. Terra no Brasil nao parece ser um fator escasso, ainda que finito. Tempo parece ser um fator, se nao escasso, pelo menos limitante. Em vista disso devem ser introduzidos no processo... |

| O trabalho apresenta um levantamento dos documentos gerados no CPATSA, em 1982, para avaliar e comparar a produção científica, com resultados do ano anterior, e a análise das citações bibliográficas dos documentos gerados; analisar o comportamento do usuário em relação do uso do acervo e a atuação do Setor de Informação e Documentação. Os resultados revelam que, em 1982, foram produzidos 98 trabalhos de pesquisa em andamento, verificou-se que, em 93 projetos, 62 não geraram publicações. |

| Based on me data concerning detailed survey on land in the year 2009 and land change in the year 2010 in Rong County, a mountainous region of Sichuan Province, by using quantitative geographical model, we conduct quantitative analysis of the status quo of land use in Rong County in terms of land use diversification, land use centralization, land use combination type, land use geographic significance and comprehensive use degree of land use. m e results show some characteristics as follows. Firstly, land use in study area displays prominent characteristic of diversification: there is a high degree of completeness land use type; there is a great similarity among towns. Secondly. there is limited combination number of land use type; mostly the combination... |

| Empirical analysis of rural credit market failure has been of key scientific and political interest in recent years. The aim of this paper is to give an overview of various methods for measuring credit rationing of farms employed in the literature. Furthermore, based on a common analytical framework entailing a formal model of a credit rationed farm household, the methods are subjected to a comparative evaluation of their specific strengths or shortcomings. Six approaches are distinguished: measurement of loan transaction costs, analysis of qualitative information collected in interviews, analysis of quantitative information collected in interviews by using the credit limit concept, analysis of spill-over effects with regard to secondary credit sources,... |
