- Abstract:
- ... Deltamethrin (S)-alpha-cyano-3-phenoxybenzyl (1R,3R)-3-(2,2-dibromovinyl)-2, 2-dimethylcyclopropane-1-carboxylate is classified as a pyrethroid pesticide that is largely used as an acaricide and scabicide. For bovines, especially, the treatment is done with the aid of dipping baths of the pyrethroid solution. Analytical control of the concentration of deltamethrin in these baths must be done perio ...

- Abstract:
- ... A flow injection spectophotrometric method for the determination of carbofuran in commercial pesticide formulations was developed. The determination involves on-line hydrolysis of the extracted carbofuran at room temperature with sodium hydroxide. The resulting carbofuran-phenol is coupled with diazotized 4-aminobenzoic acid in order to achieve an appropriate selectivity and sensitivity for the sp ...

Although the possibility of sexual transmission of T. cruzi has been suggested since its discovery, few studies have been published on this subject. We investigated acquisition of T. cruzi by sexual intercourse in an exp ...
