The dependence of superlattice thermal conductivity on period length is investigated by molecular dynamics simulation. For perfectly lattice matched superlattices, a minimum is observed when the period length is of the order of the effective phonon mean free path. As temperature decreases and interatomic potential strength increases, the position of the minimum shifts to larger period lengths. ...

This study was conducted to evaluate the effects of feeding mash versus pellet with different thermal process on blood metabolites, carcass characteristics and broiler performance. 192 (one-day) Cobb broiler chicks were used in a completely randomized design with 4 experimental groups (diets) and 4 replicates of ten chicks each (totally 16 pens). The experimental treatment groups consisted of m...

in this study, effect early age feed restriction and thermal conditioning on growth ,carcass characteristics broiler chickens subjected to heat stress was evaluated. three hundred chicks (cobb500) were randomly divided into four equal groups as treatments including thermal conditioning group (tc), feed restriction-thermal conditioning group (tcfr), feed restriction group (fr) and control group ...

the calling behavior of virgin carob moth females, ectomyelois ceratoniae (zeller) (lep.: pyralidae) was evaluated under two different thermal regimes, cycling and constant temperatures under laboratory condition. the period of calling activity under cycling temperature was prolonged and the total period of calling activity of an individual female was increased. although moths maintained under ...

In this paper, kinetic models are discussed with respect to their uses in describing the intrinsic thermal mortality of insect pests. A unique heating block system was used to obtain kinetic information for the thermal mortality of codling moth larvae. The kinetic data demonstrated the possibility to develop high-temperature-short-time thermal treatments to control codling moth and reduce therm...

An observed increase in air temperature can lead to significant changes in the phenology of plants and, consequently, changes in agricultural production. The aim of the study was to evaluate the spatial differentiation of thermal resources in Poland and their variability during a period of changing thermal conditions in Europe. Since the variability of thermal conditions is of paramount importa...
