We study uncountable structures similar to the Fraïssé limits. The standard inductive arguments from theory are replaced by forcing, so we obtain highly sensitive universe of set theory. In particular, generic investigate exist only in extensions universe. prove that most interesting cases rigid. Moreover, provide a (consistent) example an uncountable, dense reals with group integers as its aut...

background: this study was performed to induce conversion of rh strain tachyzoites of toxoplasma gondii to bradyzoites by ph changing of the cul­ture medium. methods: hela cell monolayers were infected at a 1:1 tachyzoite to cell ratio. four hours after infection, the culture medium was removed and re­placed with culture medium and 5% fcs, adjusted to ph 8 with naoh. the culture was maintained ...
