on translation of politeness strategies in dialogues involving female characters in translations and retranslations of novels translated before and after the islamic revolution of iran and their effects on the image of women: a polysystem theory approach
abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
Residual activity of Bacillus thuringiensis serovars medellin and jegathesan on Culex pipiens and Aedes aegypti larvae.
Bacillus thuringiensis serovar medellin strain 163-131 and Bacillus thuringiensis serovar jegathesan (B.t.jeg.) strain 367 are very toxic to mosquito larvae. However, they are 10 times less toxic than Bacillus thuringiensis var. israelensis (B.t.i.) to mosquito larvae under laboratory conditions. Lyophilized powders were produced from these strains and their toxicities were compared to that of ...
متن کاملToxicity of Bacillus thuringiensis var. israelensis crystals to Aedes aegypti larvae: carbonate reversal.
The toxicity of purified Bacillus thuringiensis var. israelensis crystals to larvae of Aedes aegypti could be reversed 100-fold by levels of K(2)CO(3) as low as 0.15%.
متن کاملContributions of cellular and humoral immunity of Galleria mellonella larvae in defence against oral infection by Bacillus thuringiensis.
In this study the cellular and humoral immune reactions of the Greater wax moth Galleria mellonella have been investigated during bacterial infection caused by oral administration of Bacillus thuringiensis. Two different dose strengths were investigated to assess the contribution of immune parameters to induced Bt resistance. Low-dose (sublethal LC15) infection resulted in significantly elevate...
متن کاملThe Bacillus thuringiensis Cry4Ba toxin weakens the protective function of the midgut peritrophic membrane in Aedes aegypti larvae
Background Bacillus thuringiensis (Bt) toxin Cry4Ba specifically targets the mosquito larval midgut epithelial cells for its insecticidal toxicity. Prior to reaching the midgut cells, the toxin must penetrate the midgut peritrophic membrane (PM), an acellular gut protective structure lining the midgut epithelium. However, the mechanism of toxin passage through the PM is currently unknown. To ex...
