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. Influence of meteorological variables on dengue incidence in the municipality of Arapiraca, Alagoas, Brazil
Abstract INTRODUCTION: Meteorological influences along with the lack of basic sanitation has contributed to disease outbreaks, resulting in large socio-economic losses, especially in terms of dengue. This study aimed to evaluate the meteorological influences on the monthly incidence of dengue in Arapiraca-AL, Brazil during 2008-2015. METHODS: We used gen

3. Temporal analysis and fungicide management strategies to control mango anthracnose epidemics in Guerrero, Mexico
The temporal progress of anthracnose (Colletotrichum gloeosporioides) epidemics was studied in mango (Mangifera indica) orchards treated with fungicides from different chemical groups, mode of action, and application sequences in two regions of contrasting climates (sub-humid and dry tropics) in Guerrero, Mexico. Full flowering, initial setting, and 8-15mm �

4. 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

5. Estudo do comportamento PVT de misturas de metano e fluidos de perfuração base éster / Study of the PVT behavior of methane and ester based drilling fluids mixtures
During conventional drilling operations, it is necessary to maintain the wellbore pressure greater than the reservoir pore pressure, otherwise a kick may occur. If the well control procedure is not effective during the circulation of the formation influx out of the well, a blowout could happen, which is a dangerous event concerning safety and environmental i

6. 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

7. 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

8. DETERMINAÇÃO DA DURAÇÃO DO PERÍODO DE MOLHAMENTO FOLIAR EM CULTIVOS DE BATATA / DETERMINING THE LEAF WETNESS DURATION PERIOD IN POTATO CROPS
The beginning of wetness and the end of leaf drying in potato crop was determined aiming to compare observed values of wetness duration with values estimated from meteorological data and from mathematical models. Three growing seasons with potato were performed at the experimental area of the Crop Science Department of the Federal University of Santa Maria,

9. Análise de trocadores de calor compactos para desumidificação de ar. / Analysis of compact heat exchanger for air dehumidification.
The objective of this work is to conduct a parametric analysis of the dehumidification process of compressed air in compact heat exchangers with Offset Strip Fins. The humidity carried by the compressed air should be removed from the system to prevent the condensation in the distribution lines and in the actuators or the final devices. The dehumidification p

10. Animal-environment interaction: effects of climatic environment over physiologic and productive responses of Holstein cows in free-stall / Interação animal-ambiente: efeito do ambiente climático sobre as respostas fisiológicas e produtivas de vacas Holandesas em free-stall
It has been well known the relation between the environment and physiological answers of lactating dairy cows under controlled environmental conditions. The present study aimed to monitor the animal answers allocated at typical housing system to identify the real environmental impact over it. A method was proposed to evaluate the stress level of the animal,

11. Phase equilibrium calculations for confined fluids, including surface tension prediction models
Phase equilibrium calculations for fluids confined inside capillary tubes or porous media are formulated using the isofugacity equations. In this situation, the phase pressures are not equal and it is assumed that they are related by the Laplace equation. With this formulation, existing procedures for phase equilibrium calculations can be readily modified to
