The concept of Ozone Depletion Potentials (ODPs) is extensively used in policy considerations related to concerns about the effects of various halocarbons and other gases on stratospheric ozone. Many ...
An experiment was conducted to evaluate the effect of dietary replacement of normal maize (NM) with quality protein maize (QPM) on performance, immune response and carcass characteristics of broiler (...
Iodotrifluoromethane (CF3I) has been considered to be a candidate replacement for bromotrifluoromethane (CF3Br), which is used in aircraft for fuel inerting and for fire fighting. In this study, the c...
It has been suggested that low-frequency current fluctuations in the southern Strait of Georgia are the result of baroclinic instability. However, data extracted from cyclesonde and fixed current mete...
A device is subject to damage. The damage occurs randomly in discrete time according to an increasing homogeneous Markov chain, where the incremental damage caused by a shock depends on the magnitude ...
