according to coates’s (2004, as cited in zhang, 2010) definition of "conversational dominance" (p.111), it refers to the phenomenon of a speaker dominating others in interaction. specifically, it means how a speaker makes use of certain strategies to get the floor and maintain the floor. thus, the amount of talk is the main measurement for the dominance of the conversation. whether a speaker do...

Introduction: The nucleus accumbens is involved in various functions ranging from motivation and reward to feeding and drug addiction. Some researchers have also suggested that this region has some roles in consciousness. In the present study, the effect of electrical stimulation and lesion of nucleus accumbens on Electroencephalogram waves (EEG) of addict and non-addict rats was investigated. ...

In this research, a comparison of biodiesel produced by ultrasound and heat methods was investigated. Methanol was used as the alcohol with molarity 3, 6 and 9 and KOH 0.5, 1 and 1.5 wt.% As a catalyst. In ultrasound technique, five vibrating pulse levels and three time levels were used. The results indicate that biodiesel produced by ultrasound in some properties includes a flash point of abou...

Background and Objective: Heat stress is one of the most important environmental pressures which can reduce sexual performance. Garlic has been proposed for increasing resistance against stress. This study dealt with the effects of garlic hydroalcoholic extract on reproductive hormones in male mice under heat stress. Materials and Methods: Fifty male mice were studied in five groups (n=10). ...

Abstract: After 2003, another hot summer took place in Western and Central Europe in 2015. In this study, we compare the characteristics of the two major heat waves of these two summers and their effect on the heat related mortality. The analysis is performed with focus on South-West Germany (Baden–Württemberg). With an additional mean summer mortality of +7.9% (2003) and +5.8% (2015) both year...

heat stress is an important and serious threat at work and is a particular concern in outdoor occupational environments. this study aims at comparing heat stress and heat strain at different outdoor groups, examining the protective and adaptive actions which were done by workers and also provi services to them by government or employer to reduce heat load. this cross–sectional study was conduct...

Severe heat waves have occasionally led to catastrophic avian mortality in hot desert environments. Climate change models predict increases in the intensity, frequency and duration of heat waves. A model of avian evaporative water requirements and survival times during the hottest part of day reveals that the predicted increases in maximum air temperatures will result in large fractional increa...

iran is located between two lithospheric plates (euroasia, arabian) and these two plates converge toward each other with a velocity of 25 mm/yr rate. shortening that produced from this convergence with makran subductin shows faulting and folding in zagros orogenic belt, alborz and kopedagh in north and sliding in sum strike slip faults with north-south trend in central iran. the nw-se trending ...

BACKGROUND Understanding the health impacts of heat waves is important, especially given anticipated increases in the frequency, duration, and intensity of heat waves due to climate change. OBJECTIVES We examined mortality from heat waves in seven major Korean cities for 2000 through 2007 and investigated effect modification by individual characteristics and heat wave characteristics (intensi...

Current and projected heat waves are examined over California and its sub-regions in observations and downscaled global climate model (GCM) simulations. California heat wave activity falls into two distinct types: (1) typically dry daytime heat waves and (2) humid nighttime-accentuated events (Type I and Type II, respectively). The four GCMs considered project Type II heat waves to intensify mo...
