The First Look Survey (FLS) is the first scientific product to emerge from the Spitzer Space Telescope. A small region of this field (the verification strip) has been imaged very deeply, permitting the detection of cosmologically distant sources. We present Westerbork Synthesis Radio Telescope (WSRT) observations of this region, encompassing a ∼ 1 sq. deg field, centred on the verification stri...

background: educational centers have higher standards for controlling noise pollution as it has been shown that noise pollution is a major cause of discomfort for teachers and students. noise pollution reduces concentration, interferes in the conversation, and leads to dropouts and lower grades especially in mathematics. the present study aimed to evaluate noise pollution in the schools of birj...

background: ototoxic chemicals can impair the sense of hearing and balance. in the past decades, the ototoxicity of solvents and their interaction with noise have become evident. this study has been carried out in the shoe manufacturing factory in tehran (iran) with the aim of evaluating the combined effects of noise and toluene on the workers' hearing. materials and methods: this cross-se...

in the present paper, an analysis was carried out to investigate effects of radiation on a free convection flow bounded by a vertical surface embedded in a porous medium with constant suction velocity. it was under the influence of uniform magnetic field in the presence of a homogenous chemical reaction and viscous dissipation with constant heat and mass flux. the non-dimensional governing equa...
