Step-stress accelerated degradation test (SSADT) is a useful tool for assessing the lifetime distribution of highly reliable products (under a normal-use condition) when the available test items are very few. Recently, an optimal SSADT plan has been proposed in the literature which is based on the assumption that the underlying degradation path follows a Wiener process. However, the degradation...

The anti-alpha-haemolysin test is widely used in the diagnosis of staphylococcal osteomyelitis. An additional test would be welcomed because raised antibodies to this antigen are not seen in all proven cases. This communication reports that anti-gamma-lysin was present in the serum of most of the 19 patients with proven staphylococcal osteomyelitis studied here. In two cases followed up after c...

Background: Currently available radioprotectors are poorly tolerated in man and the general use of aminothiols is compromised by their side effects. This study was carried out to test and compare the radioprotective potential of cimetidine and famotidine against lethally gamma irradiated NMRI mice. Materials and Methods: Adult male NMRI mice in groups of 10 were exposed to various doses of gamm...

We study eight different gamma-ray burst (GRB) data sets to examine whether current GRB measurements -- that probe a largely unexplored part of cosmological redshift ($z$) space can be used reliably constrain model parameters. use three Amati-correlation samples and five Combo-correlation simultaneously derive correlation parameter constraints. The intrinsic dispersion each set is taken as good...
