Intraluminal pressure change in the pharyngeal phase of swallowing was measured by the station pull-through method, in which a pressure transducer probe was being withdrawn at each 1 cm step from a segment 25 to 8 cm from the nostril. The probe had an outside diameter of 5.0 mm in size and was loaded with two miniature pressure transducers 3 cm apart from each other. Electromyogram of the supra...
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 ...

Toshka Project is one of the major and national irrigation projects planed to increase the cultivated areas in the south valley, improve the opportunity for better jobs and increase the income for the country. The project impacts and consequences should be studied carefully to maximize the intended benefits and reduce any expected side effects. This paper is proposed to study the effect of the ...
The "North Atlantic Oscillation (NAO)" as defined in Walker and Bliss (1932) has been traditionally viewed as a teleconnection pattern with 'centers of action' in the Atlantic sector. In contrast, the "zonal index cycle", as articulated by Namias (1950), involves the interactions between a fundamentally zonally symmetric or 'annular’ mode and the eddies. The perceived dynamical significance of ...
Background and Objectives: Silica is an inorganic material that found in the nature in various forms. The hazards of crystal of silica or α-quartz (free silica) is greater than other forms. Exposure to dust that contains free silica result to pulmonary injury and result to silicosis and death finally. The present research was conducted in order to evaluate the level of workers exposure to free ...
The main purpose of this study is the survey of the atmospheric low pressure effects at sea level oscillations in the Qeshm Channel. For this purpose, the curves of the pressure on the Persian Gulf and Oman Sea, during the passing of the atmospheric low pressure system, are extracted across the region. During the time of occurrence of these events, sea level oscillations in the coastal areas of...
