Suckling behavior adaptations are components of a reproductive strategy for successful breeding and offspring survival. In ungulates, maternal care of their young can be roughly classified into two dichotomous strategies: “hiding” and “following.” Since goitered gazelles (Gazella subgutturosa) are a hiding species, we predicted that during the hiding period, suckling of young would be distributed...
The power output and thermal efficiency of a finite-time, optimized, extra-terrestrial, solar-radiant Stirling heat engine has been studied. The thermo-dynamic model adopted is a regenerative gas Stirling cycle coupled to a heat source and heat sink by radiant heat transfer. Both the heat source and sink are assumed to have infinite heat-capacity rates. Expressions are obtained for optimum power...
