Heat Requirements of Two Layer Strains Placed on Different Dates 89
Gencoglan,S.
ABSTRACT This study was conducted to calculate the heat requirements of Hy-line W-36 and Hy-line W-98 layer chicks placed on different dates, and to select one of these strains based on heat requirements and egg prices. An environmentally-controlled, mechanically-ventilated, and fan and pad-cooled house with a capacity of 94,500 chicks was designed. Based on the identification of September as the month with the highest egg prices, placement dates were selected (16th of March, 1st of April, 16th of April, 23rd of April and 1st of May) to coincide with economic egg weight in that month. The heat requirements for a rearing period of 35days of both evaluated strains starting on the above-mentioned dates were calculated using heat and moisture balance method...

Variabilité de la salinité de surface d'après un modèle global de couche mélangée océanique 5
Michel, Sylvain.
Sea surface salinity (SSS) influences numerous oceanic phenomena, for instance surface water ventilation, deep water formation and thermohaline circulation. SSS also controls some ocean-atmosphere coupled processes, such as the intensity of freshwater flux and the penetration of heat flux and turbulence. Salinity is more difficult to measure than temperature from in situ surveys, which results in 20 times less data being currently available. Moreover, sea surface temperature (SST) is routinely estimated from satellites, which is not possible yet for SSS. Two space missions will fill this gap soon: SMOS from the European Space Agency and Aquarius/SAC-D from NASA and CONAE. To contribute to the SMOS project, we propose a method for estimating SSS from...
