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 water...

Performance advantages of incorporating fluid channels into foam made of DERTEX VN600 (Vinyl Nitrile) are evaluated. This foam has the potential to replace the traditional foam material of helmet liners, like Expanded Polystyrene (EPS). Experiments involved dropping a certified size E headform vertically onto a flat, solid anvil. Elastically deformable and resilient VN foam outperformed EPS dur...

The use of chemicals or bio-larvicides for the control of Culex quinquefasciatus and Anopheles stephensi breeding in pit latrines and overhead tanks (OHT) respectively is discouraged owing to many undesirable impacts in the environment. Due to faecal contamination and poor survival, use of predatory fish in OHTs is not feasible. The use of expanded polystyrene (EPS) beads is a potential alterna...

The present study focuses on the development and characterization of epoxy syntactic foam filled with epoxy hollow spheres (ESF/EHoS). The epoxy syntactic foam (ESF) was produced by embedding epoxy hollow spheres (EHoS) into a mixture of epoxy-hardener and 3% KOH solution. An innovative approach and simple procedure was implemented in the preparation of the EHoS where expanded polystyrene (EPS)...

Rehabilitation of facades may be carried out with the application External Thermal Insulation Systems (ETICS). Their main contribution is increase energy efficiency buildings. In literature, hygrothermal, impact and fire performance studies have been on several systems different insulation materials, such as expanded polystyrene, mineral wool extruded polystyrene foam insulation. Due to growing...

This paper presents the results of research on influence perforation and slits water vapour diffusion expanded polystyrene (EPS) size number perforations thermal conductivity EPS board. The was conducted using numerical models (control volume methods) with varying sample thickness, slit spacing, depth diameter perforations. model showed that it is possible to obtain up 42.18 % better compared b...
