In this investigation, a numerical model expressing advection and diffusion effects is used to examine air temperature rise in urban areas that are on the leeward side of green areas. The model results are then verified by comparison with measurement results. When the measurement point is at a distance of 30 m or more from a green area, the air temperature of the urban area is not affected by t...

Biological effects due to RF whole-body exposure can be caused by core temperature rise. According to safety guidelines, therefore, whole-body averaged specific absorption rate (WBA-SAR) is being used as a metric for human protection. The threshold level causing thermal effects was determined based on animal experimental results. In order to investigate the relationship between WBA-SAR and core...

NNowadays, car manufactures in order to increasing torque and power with consider to fuel consumption, have swept to production of turbocharged engines. With consider to exhaust gas-temperature rises in boosted engines, recognition of critical locations of exhaust manifold in the worse condition of engine (full load and maximum speed), to prevent fracture of exhaust manifold is very important. ...

This study explores the intonational signalling of a ‘request address’ in German and Swedish. Data from 16 speakers (9 Germans, 7 Swedes) were elicited under controlled conditions, and intonation contours produced on the test phrase “Wallander?” were classified according to their phrase-final pattern. Both ‘rises’ and ‘fall-rises’ were produced frequently by both Germans and Swedes, which is in...

Coral bleaching due to thermal and environmental stress threatens coral reefs and possibly people who rely on their resources. Here we explore patterns of coral bleaching and mortality in East Africa in 1998 and 2005 in a region where the equatorial current and the island effect of Madagascar interact to create different thermal and physicochemical environments. A variety of temperature statist...

The contribution of nitrogen (N) supply is an essential source for the growth of apple trees from budding to fruiting. In new apple-producing regions of north China, such as the Shenyang area, air temperature rises rapidly, while in contrast, soil temperature rises very slowly. In such weather conditions, the amount of nitrogen absorbed by the roots is not sufficient for the growth and developm...

Abstract Inorganic adhesive is widely used in the sealing and connection of electronic devices. Its insulation highly important performance installation. In this paper, resistance tensile strength different composite silicate samples were measured by test machines. The morphology surface composition analyzed microscope energy spectrum analyzer. results show that: a humid environment, increases ...

INTRODUCTION The aim of this in vitro study was to compare the temperature rises in the pulp chamber and time spent with different techniques for orthodontic resin adhesive removal. METHODS AND MATERIALS Adhesive removal was performed in 20 extracted human maxillary second premolars with five techniques: high-speed tungsten carbide burs with water-cooling (BurH-cool) and without cooling (BurH...

testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
