1. INGESTIVE BEHAVIOR OF SANTA INÊS SHEEP UNDER THERMONEUTRALITY AND THERMAL STRESS UPON CONSUMPTION OF SALINE WATER
ABSTRACT The consumption of saline water in semiarid regions is a recurrent situation that can affect the ingestive behavior of small ruminants. This study evaluated the ingestive behavior of Santa Inês sheep maintained in a climatic chamber under two air temperatures -25 °C within the thermal comfort zone (TCZ) and 32 °C above the TCZ - and consuming wat

2. HYBRID SYSTEM SIMULATION TO SUPPLY HEATED AIR TO A SOLAR FOOD DRYER
ABSTRACT The intermittence of solar radiation, due to continuous rainy or cloudy days, is a limitation of simple and small solar dryers. These conditions often make them impossible to use. By including storage systems (thermal accumulation) and/or auxiliary energy sources, drying processes or dehydration can be conducted continuously, even during periods of

3. Postharvest 1-methylcyclopropene treatments maintain the quality of Rosa sterilis D. shi during storage
Abstract Effects of different concentrations of aqueous 1-methylcyclopropene (1-MCP) on Rosa sterilis D. shi fruits were investigated. The fruits were harvested at commercial maturity stage and treated with 1-MCP treatment at 0.5, 1.0, and 1.5 μL L-1 for 20 h at 25 °C in an air tight chamber along with control sample to evaluate the effect of 1-MCP concent

4. Effect of biostimulant application and long-term storage on the nutritional value of carrot
RESUMO O valor nutricional da cenoura é determinado pelo teor de açúcares totais e monossacarídeos, carotenóides e vitaminas, incluindo vitamina C, em suas raízes. Em 2009-2011, foram realizadas pesquisas de campo visando o efeito de preparações bioestimulantes, aplicadas durante o período vegetativo da cenoura, sobre os nutrientes selecionados de s

6. Drying of microalga Scenedesmus obliquus BR003 in a gas dryer at low temperatures
ABSTRACT: Development of efficient and specific equipment to dry microalgae is essential for commercial use of these microorganisms that show high growth rates and biotechnological potential. Drying costs of microalgae biomass are still high and they should be reduced for the production of compounds with low added value. Therefore, we evaluated the drying p

8. Experimentation and modeling of soil evaporation in underground dam in a semiarid region
RESUMO Nas regiões semi-áridas, as altas taxas de evaporação interferem na disponibilidade de água no solo. Normalmente, é difícil medir e modelar a evaporação devido à complexidade dos métodos disponíveis, ao baixo teor de umidade do solo e à baixa concentração de vapor de água no ar. Isso também pode dificultar o monitoramento e a simula�

9. Effect of different stripping techniques on pulpal temperature: in vitro study
RESUMO Introdução: o desgaste proximal do esmalte é um procedimento clínico rotineiro utilizado na Ortodontia para se criar espaços ou equilibrar discrepâncias de tamanho dentário. Esse procedimento pode resultar em transferência de calor para a polpa, predispondo-a a mudanças histopatológicas e necrose do tecido pulpar. Objetivo: medir as mudan

10. Influence of Drying Conditions on the Final Quality of Cherry and Grape Tomatoes
ABSTRACT The convective drying process of cherry and grape tomatoes for dried tomato production was studied taking into account operational and sensorial aspects. The tomatoes were physicochemical characterized and dried at three air temperatures in a drying chamber. Thus, it was possible to the determinate the physicochemical characteristics, drying kinetic

11. Artificial neural networks modeling of kinetic curves of celeriac (Apium graveolens L.) in vacuum drying
Abstract The objective of this study was to predict celeriac drying curves using artificial neural networks (ANNs). The experimental data for vacuum drying kinetics of celeriac slices reported by other researcher in the previously published article was used. The air temperature, chamber pressure and time values were used as ANN inputs. To predict the moistu

12. INFLUÊNCIA DO ENVELHECIMENTO ACELERADO EM FLARES MAGNÉSIO/PTFE/FPM
Magnesium/PTFE/FPM decoy flares, also named conventional flares, were designed in order to protect combat aircraft from the threat caused by infrared-guided missiles. Adverse storage or transport conditions may cause reactions that deteriorates chemical properties of the conventional flares, causing the aging and compromising its performance. The aim of this
