Dipping tests with DDT for the control of three species of goat lice, two Mallophaga and one Anoplum, were conducted at Menard, Tex. Angora goats infested with the yellow louse, Trichodedes lzermsi Kellogg and Nakayama, and the red lice, T. Cf/prae Gurlt and T. limbatus Gervais, were dipped in 0.3 and 0.6 per cent of the cbemical in a water emulsion. In every case all the lice were killed soon ...

BACKGROUND & OBJECTIVES Aedes albopictus is one of the vectors for dengue and chikungunya and emergence of pyrethroid resistance in this species could be of a major concern in controlling the vector. This study reports insecticide susceptibility status of Ae. albopictus to DDT and pyrethroids in some Indian populations and status of presence of knockdown resistance (kdr) mutations. METHODS Th...

In order for a double-detonation model to be viable normal type Ia supernovae, the adverse impact of helium-burning ash on early-time observables has avoided, which requires that helium envelope mass should at most 0.02 solar mass. Most previous studies introduced detonation by artificial hot spots, and therefore robustness spontaneous remains uncertain. present work, we conduct self-consistent...

background and aim: hearing impaired students experience binaural hearing like normal peers and school age is challenging time for using dichotic listening. lack of research was found on relationship of persian hearing impair­ed children with central auditory processing (cap). one of the aims of this study was a comparison between persian dichotic digit test (ddt) score in children with mild an...

Inhabitants of dwellings treated with DDT for indoor residual spraying show high DDT levels in blood and breast milk. This is of concern since mothers transfer lipid-soluble contaminants such as DDT via breastfeeding to their children. Focusing on DDT use in South Africa, we employ a pharmacokinetic model to estimate DDT levels in human lipid tissue over the lifetime of an individual to determi...

OBJECTIVES The aims of this study were to determine the prevalence of extended-spectrum beta-lactamases (ESBLs) in AmpC-carrying Enterobacter spp. in a tertiary care university hospital in Vienna, Austria, and to implement a cost-effective strategy to detect ESBLs in this particular genus on a routine basis. METHODS Clinical Enterobacter isolates (n=208) were investigated by means of (i) an i...
