use of expanded polystyrene (eps) and shredded waste polystyrene (swap) beads for control of mosquitoes
background: mosquitoes transmit several diseases to human. there are several measures for control of larvae. as part of integrated vector management (ivm) program, the utility of floating layers of polystyrene beads (eps) is a potential alternative in habitats of mosquito larva. eps beads prevent oviposition of mosquito as well as killing the immature stages by forming a tick layer on the w...

متن کاملPhotodegradation of Optically Trapped Polystyrene Beads at 442 nm
Polystyrene particles of different sizes are optically trapped with a gaussian beam from a He-Cd laser operating at 442 nm. The particles are observed to exhibit luminescence after a certain trapping time followed by an escape from the optical trap. The observed luminescence is explained in terms of the photodegradation of the polystyrene backbone. It is speculated that these chemical modificat...
متن کاملMetal-Containing Polystyrene Beads as Standards for Mass Cytometry.
We examine the suitability of metal-containing polystyrene beads for the calibration of a mass cytometer instrument, a single particle analyser based on an inductively coupled plasma ion source and a time of flight mass spectrometer. These metal-containing beads are also verified for their use as internal standards for this instrument. These beads were synthesized by multiple-stage dispersion p...
متن کاملAdjusted Density High-strength Concrete Using Expanded Polystyrene Beads
This paper reports the results of an experimental investigation into the effects of incorporating varying amounts of expanded polystyrene beads on the engineering properties of high-strength concrete. It was observed that a density reduction of 8.3% caused compressive strength, tensile strength and modulus of elasticity to reduce by 48%, 39% and 15%, respectively. Drying shrinkage was marginall...
