A testing strategy and corresponding test plan have been presented for the two proposed US candidate breeder blankets: (1) a helium-cooled solid breeder concept with ferritic steel structure and Be neutron multiplier, but without a fully independent TBM and (2) a dual-coolant helium-cooled ferritic steel structure with self-cooled LiPb breeding zone that uses a flow channel insert as MHD and th...

This experiment was one part of a larger study investigating problems of aggression towards females by male broiler breeder fowl. To investigate causal mechanisms, we were interested in determining (1) if feed-restriction during rearing affects behaviour towards females at sexual maturity and (2) if aggressiveness towards females is correlated with general levels of aggressiveness. We compared ...
Severe myocardial necrosis was produced in virgin Sprague-Dawley rats without preexisting arteriosclerosis and in breeder Sprague-Dawley rats with various degrees of arteriosclerosis by giving two subcutaneous injections of isoproterenol; the virgin rats received 50 mg/100 g and the breeder rats 25 mg/100 g body weight. Breeder rats withstood the stress and shock of myocardial necrosis with few...
