one of temperature estates is hot day occurrence. in order to recognize the mechanism of this estate, surveying its spatial behavior is crucially important. in current paper it has been attempted to recognized widespread hot days and their spatial distribution by using statistical methods. accordingly maximum temperature database of iran during 1962-2008 has been used. the analyses result has i...

STUDY OBJECTIVE This study investigated the relation between heat and mortality in London to determine the temperature threshold at which death rates increase and to quantify the effect of extreme temperatures on mortality. DESIGN Daily data on all cause mortality and temperature were obtained for a 21 year period and the relation between them investigated both graphically and by using non-pa...

We examined the impact of extreme temperatures on mortality in 12 counties across Hubei Province, central China, during 2009-2012. Quasi-Poisson generalized linear regression combined with distributed lag non-linear model was first applied to estimate county-specific relationship between temperature and mortality. A multivariable meta-analysis was then used to pool the estimates of county-speci...

transfer table is an essential stage between roughing and finishing rolling stands in a hot-strip rolling mill. high temperature and long time that strip is exposed to air at this stage cause a considerable heat loss that accounts for uneven temperature distribution, non-uniform surfaces, reduced product quality and increased production costs. using thermal shields on the transfer table is cons...

In this research, the hot deformation behavior of W360 tool steel was investigated using hot compression test at 1000-1200°C and strain rates of 0.001, 0.01, 0.1, and 1 s-1. According to the results, dynamic recrystallization was found the most important restoration factor of this alloy during hot deformation. Recrystallization was enhanced with an increase in temperature and strain rate. Also,...

The hot-hand phenomenon, according to which a player's performance is significantly elevated during certain phases relative to the expected performance based on the player's base rate, has left many researchers and fans in basketball puzzled: The vast majority of players, coaches and fans believe in its existence but statistical evidence supporting this belief has been scarce. It has frequently...

Global warming is widely regarded to have played a contributing role in numerous past biotic crises. Here, we show that the end-Permian mass extinction coincided with a rapid temperature rise to exceptionally high values in the Early Triassic that were inimical to life in equatorial latitudes and suppressed ecosystem recovery. This was manifested in the loss of calcareous algae, the near-absenc...

BACKGROUND Headache is one of the most common complaints in today's society. Patterns and prevalence of headache, especially headaches associated with physical activity (Exertional Headache) in the population of conscripts in our country is unknown. OBJECTIVES In this cross sectional study we tried to answer these questions to some extent. PATIENTS AND METHODS Using a Persian questionnaire ...
