tetanus is an important disease which created by tetanospasmin toxin of clostridium tetani. in this study we surveyed six important factors including lf, kf, mld, ph, od and total protein assay of harvard 52 (h52), g5 (hg5) and 49205 (h49205) strains of the bacterium to determine which of them were more suitable for use in vaccine production. the mentioned strains were seperatedly reactivated i...

The comments I offer in this memorandum on the MAC’s recommendations are limited to the issues listed below. In many cases, I agree with the MAC’s recommendations, and offer comments in order to contribute to broader debates about climate policy design in California, which will continue for years to come. There are also instances where I disagree with the MAC’s conclusions or believe the MAC fa...

Nearly all economic models of the household have implications for how characteristics of the children in a family affect human capital investments in their siblings. Much evidence suggests that perceived returns to investing in sons is higher than investing in daughters in many economies (often due to cultural practices rather than inherent productivity differences). When this is so – and where...

The Mark II experiment first started taking data in 1978 at the SLAC SPEAR storage ring. It was the first e+edetector with a large, many layer cylindrical drift chamber (CDC) and a large liquid argon calorimeter!” After two years at SPEAR, it was moved to the PEP storage ring, where it was upgraded a year later with a seven layer precision vertex drift chamber!’ located between the CDC and the ...

Results on t/decays from Mark III are presented. With a data sample of 240,000 @events, we measure w’+x+K-~, @+rlv, t/+~~, w’+‘y4x*, @+@x*, and perform a search for -t/-+pz Implications of our measurements are discussed.
