1. What is the best temperature-humidity index equation to indicate heat stress in crossbred dairy calves in a tropical environment?
RESUMO: Objetivou-se determinar dentre nove equações do ITU a que melhor representa os efeitos do estresse por calor para bezerros leiteiros mestiços criados em ambiente tropical. Foram avaliados 12 bezerros, machos e fêmeas, com idade de 20 a 60 dias, criados no bezerreiro tropical. As frequências respiratória (FR) e cardíaca (FC), as temperaturas re

2. Cinética de secagem de café natural e suas relações com a qualidade para diferentes temperaturas e umidades relativas do ar / Drying kinetics of natural coffee and its relationship with the quality for different temperatures and relative humidity of air
O processamento do café pela via seca, pelo qual são produzidos os cafés naturais, é o método mais utilizado no Brasil. Frequentemente, são encontrados relatos na literatura que indicam pior qualidade do café natural em relação aos cafés processados pela via úmida, tornando-se necessário investimentos em pesquisas, no Brasil, tendo em vista a pro

3. Avaliação da influência da temperatura e ponto de orvalho no recozimento final de aços elétricos semiprocessados e totalmente processados / Evaluation of the influence of final annealing heat treatment temperature and dew point in semi-processed and fully processed electrical steels
Semi-processed electrical steels require annealing after processing in the motors manufactures to improve motors efficiency by reducing losses and increasing permeability. Annealing in fully processed electrical steel is performed to relax the residual stress and promote recovery or recrystallization of distorted parts. Commercial samples from different stee

4. Mudanças climáticas e ferrugem asiática da soja no Estado de Minas Gerais / Climatic changes and the soybean asiatic rust in Minas Gerais State
In 2001, the soybean Asian rust caused by the fungus Phakopsora pachyrhizi (Syd &P. Syd) appeared in the South American continent, as causing many damages to the crops in Brazil, mainly in the states of Mato Grosso, Goiás, Minas Gerais and Mato Grosso do Sul at the seasons 2004/2005 and 2005/2006. The temperature, air relative humidity and the presence of t

5. Operating microscope eyepiece heaters.
Precipitation of water vapour from expired air on to exposed eyepiece lenses of operating microscopes can seriously interfere with the surgeon's view. By warming these optical surfaces to temperatures well above the dew point of expired air this problem is eliminated. A pair of small heaters were designed to clamp over the eyepiece tubes of a standard opera

6. Influence of Temperature Gradients on Leaf Water Potential 1
Water potential was monitored at nine locations along single maize (Zea mays L.) leaf blades with aluminum block in situ thermocouple hygrometers. Water potential showed a continuous decrease toward the tip, with a 2- to 4-bar difference between leaf base and tip under both moist and dry soil conditions. The water potential difference between the soil and th
