Abstract: In foundry industry the shot blasting process plays a vital role for clean, strengthen or polish the metal, in foundries the handling of shot blasting machines having most hazards related to health, safety & Environment are involved. It may cause eye, skin and respiratory tract irritation to health. Particularly in aluminium foundries the aluminium dust emission product is a white crystalline powder and it has the characteristics of forming explosive dust in the air mixtures...........

Key words: Shot Blasting, Hazards, Emission, Exposure, Health Effects.

Abstract: The diversity of SRES scenarios that has potential to produce different increment of climatic trend reflects to the future expectation on development patterns. The selection of an appropriate emission scenario is important to present the appropriate climatic trend suit to the site study. The main objective is to determine appropriate emission scenarios and potential increment of rainfall in the upcoming year Δ2020 and Δ2050 for site study. Two climate projection models; SDSM and PRECIS models were used to generate the future rainfall.......

Abstract: Better surface quality and longer functionality of cylindrical parts are the demands of the industries such as automobile, aircraft, machine tool, pneumatic and hydraulic equipment, railways and so on.Burnishing is considered as a chipless cold working finishing process and improves the surface finish of workpieces that have been previously machined. In Roller burnishing, Surface finish is achieved by flattening the rough peaks by compressive force of the rollers.............

Key words: Roller burnishing, Taguchi method, Surface roughness
