Microcredit has been proposed as a tool for poverty reduction. However, little is known about the way banks determine loans terms and if the credit supplied is enough to satisfy demand. This paper, firstly, proposes a theoretical model to analyse microcredit interest rates and amounts. Secondly, the model predictions regarding loans' size are tested using a disequilibrium model and data from a developed country...
Os herbicidas utilizados no sistema Clearfield® de arroz irrigado são persistentes e móveis no solo, portanto práticas de manejo podem influenciar na sua dinâmica no ambiente. O objetivo deste trabalho foi determinar o efeito de três manejos de irrigação da cultura do arroz na lixiviação da mistura formulada dos herbicidas imazethapyr e imazapic, em solo de várzea. O experimento consistiu de um ensaio de campo ...
Foram revisados casos de defeitos congênitos (DCs) diagnosticados em bovinos no Laboratório de Patologia da Universidade Federal de Santa Maria em 1964-2010. Durante o período estudado, foram examinados materiais provenientes da necropsia de 7.132 bovinos e foram encontrados 31 bezerros (0,4%) com DCs, os quais foram classificados em 34 tipos e alocados nos sistemas orgânicos primariamente afetados. Os DCs ocor...
The circulation of West Nile virus in Portugal was assessed by serological surveys conducted during 2004–2010 in horses and birds. The detection of WNV antibodies in both species in all the years covered by the study as well as the presence of anti-WNV IgM in symptomatic horses that had not traveled outside the country, support the notion that WNV circulates in Portugal.
We evaluated genetic variants of apolipoprotein E (APOE HhaI) and their association with serum lipids in colorectal cancer (CRC), together with eating habits and personal history. Eight-seven adults with CRC and 73 controls were studied. APOE*2 (rs7412) and APOE*4 (rs429358) were identified by polymerase chain reaction-restriction fragment length polymorphism. APOE gene polymorphisms were similar in both groups...
Alterações oftálmicas foram experimentalmente induzidas em caprinos após superdosagem com o anti-helmíntico closantel. Foram usados cinco caprinos com sete a oito meses de idade, produtos do cruzamento da raça Saanen com a Pardo Alpino. Os animais mostraram sinais de intoxicação entre quatro e cinco dias após a administração do closantel. Os sinais clínicos caracterizaram-se principalmente por distúrbios neurol...

ABSTRACT: The project "Conservation and Management of the Biodiversity of the Cerrado biome - CMBBC", chose as its regional study area, the geographical region of northeastern Goiás called Paranã-Pirineus. One of the initial tasks of this project was the socioeconomic characterization of the 34 cities and towns (municipalities) which comprise the Paranã-Pirineus regional study area. In order to compare these ci...
