the holy surah “al- shams” with its effective musical sound is striking in ear and heart and includes various meanings in its few words. shortness of distances and abundance of swears and various contradictions is evident in it which led me to study it in three levels of stylistics: phonetic level, combination level and semantic level.the aim of this study is to explore the beauties of its styl...

the present work is the successful extension of an improved equation of state (eos) to refrigerant fluids. the objective is the prediction of isothermal and saturated liquid densities of refrigerants. two temperature-independent parameters appearing in the modified eos are closely related to critical point properties of refrigerant fluids. our results showed that, the proposed eos can predict w...

it is accepted that noise pollution has a major impact on health, such as physical, physiological, psychological and performance related effects, all over the world. this study aims to evaluate noise pollution in four urban parks located in sanandaj city, iran and to zone it in gis environment. sound pressure level (spl) and maximum sound level (lmax) were measured at 45 points (each point was ...

oroginal article tiller is a handy multi – a purpose tractor is used in agriculture. the noise emitted from tiller may be seriously affected auditory system users. the purpose of this study was to evaluate the exposure to noise in operators of this device. in this study 36cultivator tiller was examined. measurement of sound is based in iso 5131-1996 and iso 7216 standard and was conducted in in...

The human auditory cortex is the gateway to the most powerful and complex communication systems and yet relatively little is known about its functional organization as compared to the visual system. Several lines of evidence, predominantly from recent studies, indicate that sound recognition and sound localization are processed in two at least partially independent networks. Evidence from human...

noise level intensity in cities, due to the daily increasing sources of noise producing agents in one respect, and the lack of noise absorbants in the other respect, is rising. the high influence of intense noises on the human body and mind are found to have detrimental effects. the ideal is to have an optimal condition of noise. in this paper the living and relaxing areas, in view of main acou...
