Techniques to minimize the effects of acute heat stress or chronic in broilers
(2019-01-01)
High environmental temperature is limiting factor in broiler production. In order to minimize the undesirable consequences of acute or chronic heat stress, the techniques of fixed dietary electrolyte balance and early heat ...
Large-scale radiation and energy balances with Landsat 8 images and agrometeorological data in the Brazilian semiarid region
(Spie-soc Photo-optical Instrumentation Engineers, 2017-02-22)
Aiming to subsidize the rational water resources management, four Landsat 8 (L8) images along different conditions of the year 2014 were used for modeling the radiation and energy balances in the mixed agroecosystems inside ...
agriwater: An R package for spatial modelling of energy balance and actual evapotranspiration using satellite images and agrometeorological data
(Elsevier B.V., 2019-10-01)
Aiming to subsidize the rational water resources management, an R package called agriwater was created in order to obtain the energy balance on the soil and actual evapotranspiration using satellite imagery and agrometeorological ...
Influence of summertime mesoscale convective systems on the heat balance and surface mixed layer dynamics of a large Amazonian hydroelectric reservoir
(Amer Geophysical Union, 2014-12-01)
We evaluated the impacts of summertime mesoscale convective systems (MCS) on the heat balance and diel surface mixed layer (SML) dynamics of the Brazilian Amazon's Tucurui Hydroelectric Reservoir (THR). We used a ...
Energy balance model applied to pasture experimental areas in Sao Paulo State, Brazil
(Spie-int Soc Optical Engineering, 2016-01-01)
The Simple Algorithm for Evapotranspiration Retrieving (SAFER) was used to estimate biophysical parameters and the energy balance components in two different pasture experimental areas, in the Sao Paulo state, Brazil. The ...
Energy balance with Landsat images in irrigated central pivots with corn crop in the Sao Paulo State, Brazil
(Spie-int Soc Optical Engineering, 2014-01-01)
The energy balance (EB) components were quantified in a commercial farm with corn crop, irrigated by central pivots, in the Northwestern side of Sao Paulo state, Southeast Brazil. The SAFER (Simple Algorithm For ...
Energy balance in the watershed of Ipê, Northwestern São Paulo State, Brazil
(2016-01-01)
The region of Ilha Solteira, in the Northwestern of São Paulo State, has been undergoing significant changes in agricultural land use and cover since 2006, as pasture fields have been replaced by sugarcane crop. This drastic ...
Heat exchange and energetic balance during exercise in highlanders and lowlanders at sea level and high altitude
(Environmental Physiology, 1973)
This study was designer to determine the effects of changes in both cutaneous circulation (15) and kinetics of oxygen uptake (20) at high altitude on mechanisms of heat exchange during exercise. From a theoretical point ...
