2. Strategies used to control the costs of underground ventilation in some Brazilian mines
Abstract In an underground mine, the ventilation is responsible for 25% to 50% of its electrical energy consumption. In countries such as South Africa, United States and Canada researchers have started to achieve a significant reduction in energy consumption without neglecting aspects of the quantity and quality of air required for the best performance of th

3. FUZZY SLIDING-MODE TEMPERATURE-CONTROL SYSTEM FOR SOAKING AND GERMINATION OF RICE SEEDS
ABSTRACT The soaking and germination process of rice seeds is the starting point in rice cultivation in cold regions and has a significant effect on grain yield. Efficient techniques for controlling the water temperature in the seed tank are required to enhance germination quality. This paper introduces a fuzzy theory for designing a fuzzy logic-based slidin

5. Incorporação de biomassa de fabáceas ao substrato de plantio para controle da podridão-de-escleródio (Sclerotium rolfsii) em cubiu (Solanum sessiliflorum)
RESUMO O cultivo do cubiu (Solanum sessiliflorum Dunal), no Amazonas, é limitado pela alta incidência da doença podridão-de-escleródio (Sclerotium rolfsii Sacc.) e a incorporação de material vegetal ao substrato de cultivo altera a microflora presente. O trabalho objetivou avaliar o potencial de controle da podridão-de-escleródio em cubiu por meio d

6. Insulin resistance is associated with Sfrp5 in obstructive sleep apnea,
Resumo Introdução: A apneia obstrutiva do sono, uma doença comum, é geralmente complicada com resistência à insulina e diabetes melito tipo 2. Acredita-se que a adipocina possa ter um papel importante no desenvolvimento de resistência à insulina e diabetes melito tipo 2 na apneia obstrutiva do sono. Objetivo: Avaliar se a proteína secretada relaci
