| ABSTRACT The objectives of this study were to monitor the thermal environment of different hatchery locations during the transfer of fertile eggs from the setter and to the hatcher, to measure egg heat loss, and to determine its effects on hatchery results. In total, 1,728 fertile eggs of Cobb broiler breeders were divided into two treatments. In treatment 1 (T1), after 19 days of incubation, eggs were removed from the incubator and transferred to the hatcher in aninsulated box, and in treatment 0 (T0), eggs were transferred with no thermal insulation (T0). The duration of egg transfer was 10 minutes. Eggs were photographed using a thermographic camera at the exit of the setter, arrival at and exit from the candling room, and arrival at the hatcher.

| Polymers are widely used for passive thermal insulation coatings on steel pipe in offshore oil and gas production. In this industry, structures used in deep sea have to be reliable as they are in service for more than 20 years in a very severe environment: sea water, hydrostatic pressure, temperature. One of the main questions is how to test and predict the lifetime of such structures in the laboratory. This study presents one approach that has been developed to characterize and predict the degradation of polyurethanes used as thermal insulation materials. Based on results obtained during accelerated ageing of the PU in sea water, a prediction of degradation through the thickness has been set up taking into account the temperature profile in the coating,... |

| ABSTRACT In the swine intensive farming, one of the biggest problems is to meet the thermal requirements of piglets in heated creeps, which demand high consumption of electricity and increase in production costs. The aim of this study was to evaluate the thermal efficiency and the consumption of electric energy in heated and internal insulated creeps, made of recycled material, when compared to creeps without thermal insulation. The treatments were: control (TCON): creep heated through suspended electric resistance, controlled by thermostat; thermal insulation with recycled material (TPK). The experiment was carried out for 21 days. In the treatments, the temperature (°C) and relative humidity (RH) of the air, consumption of electric energy (kWh), specific... |
