چکیده

eggs (Webster, 1934). The results of that investigation showed that much reduced pressures were insufficient to destroy the eggs. The question is one of great importance to administrations involved in the carrying of passengers in vehicles; it is of particular importance to railway authorities in India, where constant reinfestation of passenger vehicles takes place and where conditions are eminently favourable for the development and multiplication of bugs.

Prevalence of Bed Bug Infestation (Cimex lectularius) in Prisons in Mazandaran Province, 2015-2017

 Background and purpose: Bed bugs (Cimex lectularius) are major human ectoparasites. Before planning and implementation of any control measures against bed bugs in prisons, it is essential to determine the infestation rate. Materials and methods: This descriptive cross-sectional study was performed to determine the prevalence of bed bug infestation in prisons in Mazandaran Province, 2015-2017....

Survival rates associated with in vitro low-temperature storage of kutum (Rutilus kutum) eggs

To study the effects of post-stripping oocyte ageing at low temperatures on the viability of kutum (Rutilus kutum) oocytes, unfertilised eggs of five females were stored in ovarian fluid at temperatures of 4 and 7 degree centigrade for 24 hours post stripping (HPS). The stored ova of five female kutum were separately fertilised at 0 (i.e., control eggs fertilised prior to storage), 4, 8, 12, 16...

Posttreatment Feeding Affects Mortality of Bed Bugs (Hemiptera: Cimicidae) Exposed to Insecticides.

Insecticide sprays and dusts are used for controlling bed bugs, Cimex lectularius L. In natural environments, bed bugs have daily access to hosts after they are exposed to insecticides. The established laboratory insecticide bioassay protocols do not provide feeding after insecticide treatments, which can result in inflated mortality compared with what would be encountered in the field. We eval...

Effect of Twisted Tape Baffles on Pressure Drop, Fluctuation and Expansion Ratios in gas - Solid Fluidized Bed

In the present work an attempt has been made to study the effect of the twisted tapes as bed internals, on the performance of the gas-solid fluidized beds. Experimental investigation has been carried out in cylindrical column with and without twisted tapes. Twelve numbers of twisted tapes of three different widths with four values of the twist ratios for each width were studied at different...
