In this paper the effect of site conditions, which are Altitude, Temperature and Relative Humidity and also Heat Dissipation Capacity are investigated on the optimized design of natural draft dry cooling towers with specific kind of heat exchangers, known as Forgo T60 type. A genetic algorithm program has been developed for optimized design of these cooling towers. Objective function includes b...

The present study examined the effects of low humidity and hypobaric conditions on hematological change in venous blood of the lower leg during quiet prolonged sitting. Ten healthy male students participated as the subjects after singing a consent form to participate in this study. Their diet and water intake were controlled from 19:00 on the day before the experiments. The subjects sat for 130...

the current study aims to ordinate ecological groups in the wetlands of northern and eastern slopes of the sabalan mountain and investigate their relationship with environmental variables. the location of wetlands was found using field surveys and satellite images. in total, 32 wetland sites were identified for the sampling purpose. 320 sample plots (relevé) were selected using the systematic-r...

Abstract Objective: This paper aims to conduct a study of the speed sound in Colombia for heights below troposphere, taking into account temperature as function altitude tropical zone, order determine distance lightning strike. Methodology: A profile was determined by analyzing data on altitude, temperature, and relative humidity country. The equation presented NASA International Standard Atmos...

Nasal peak inspiratory flow at altitude. P.W. Barry, N.P. Mason, J-P. Richalet. #ERS Journals Ltd 2002. ABSTRACT: The present study investigated whether there are changes in nasal peak inspiratory flow (NPIF) during hypobaric hypoxia under controlled environmental conditions. During operation Everest III (COMEX 997), eight subjects ascended to a simulated altitude of 8,848 m in a hypobaric cham...

This study aims to explore how lichen diversity, composition, and distribution vary with altitude, environmental factors (temperature relative humidity). The was conducted in the forest of Gunung Bunga Buah, Selangor at five sites (different altitudes). Forty-four species were identified. Their correlated significantly altitude factors, increasing diversity higher altitudes. Graphidaceae Physci...

BACKGROUND Bluetongue (BT) is a vector-borne disease of ruminants that has expanded its traditional global distribution in the last decade. Recently, BTV-1 emerged in Southern Spain and caused several outbreaks in livestock reaching the north of the country. The aim of this paper was to review the emergence of BTV-1 in the Basque Country (Northern Spain) during 2007 and 2008 analyzing the possi...

In the world of football, the visiting national teams are sometimes confronted with different environmental conditions: heat, cold and different relative humidities are good examples, but the most important one is the practice of football at altitude. In 2007, the Medical Committee of Federation Internationale de Football Association (FIFA) had organised a consensus meeting, with 12 internation...
