Algebraic varieties that are locally isomorphic to open subsets of affine space will be called plain. Plain varieties are smooth and rational. The converse is true for curves and surfaces, and is unknown in general. It is shown that plain varieties are stable under blowup in smooth centers.

Decolourization of wastewater from a textile plant by a marine Aspergillus niger was studied. The fungus was previously isolated from Gorgan Bay in the Caspian Sea. The kinetics of decolourization was studied by varying energy sources. The best decolourization was achieved when sucrose was used as source of carbon and energy. NH4+ ion was demonstrated to be the best nitrogen source. Color reduc...

Kid kidney cells form less than 2 months of age were grown, 80% confluent monolayers were obtained after 10-12 days. Live attenuated goat pox virus vaccine (Gorgan 55, Iranian) was used to infect the confluent monolayers. Eighty percent cytopethic effect (CPE) was obtained on day 5 of virus inoculation. TCID50 calculated for the pool virus was 10 / ml. Vaccine was found free from any bacterial ...

I define the plain Anabaptists by answering two essential questions: “Who are the plain Anabaptists” and “What are the plain Anabaptists?” In asking “Who are the plain Anabaptists?” I investigate several dimensions of identity. First, I trace the history of seven religious traditions within Anabaptism: the Swiss Brethren/Mennonites, the Low German/Russian Mennonites, the Hutterites, the Amish, ...
