background: changes in global temperature and its health effects have recently been under much investigated. consequently, these changes have affected mortality and morbidity rates which are important public health indices. the present study examines the effect of mean temperature on the frequency of hospitalization due to cardiovascular and respiratory diseases in ali ibn abi talib hospital of...

Measurements using a Pt-Rh heater strip in a high temperature X-ray diffractometer furnace show that the temperature indicated by a two-colour infra-red pyrometer directed at the upper surface of the strip is within fl “C of the temperature indicated by a Pt/Pt-lO%Rh (type S) thermocouple welded to the lower surface, over the temperature range from 600-l 100 “C. However, the temperature of a po...

We present a class of examples of nearest-neighbour, bounded-spin models, in which the low-temperature Gibbs measures do not converge as the temperature is lowered to zero, in any dimension.

Evolution of the cluster temperature function is extremely sensitive to the mean matter density of the universe. Current measurements based on cluster temperature surveys indicate that ΩM ≈ 0.3 with a 1σ statistical error ∼ 0.1, but the systematic errors in this method are of comparable size. Many more high-z cluster temperatures will be arriving from Chandra and XMM in the near future. In prep...

conclusions the fluoride content of drinking water in reservoirs and at homes was below the optimal level in mariwan. no differences were observed from the standard levels in behbahan. there were no differences in fluoride content of water in reservoirs and in home pipelines, indicating no tangible changes in fluoride content from the reservoirs to the homes. in neither of the towns was severe ...

background and objectives: the seed extract of silybum marianum contains seven flavonolignans known collectively as silymarin. these metabolites can be produced in hairy root cultures of s. marianum. the effect of different physical factors can change root biomass and silymarin production which has been investigated in the present study. methods: the effect of different physical factors of temp...

objective: drying is one of the most important post-harvesting processes in agriculture. drying method and also drying time have an important effect on the amount of energy required. in this study analysis of energy consumption for drying corn in dryer reservoir with flow of warm air and the effect of the temperature and height of product layer on the amount of energy consumption per unit mass ...

this study is concerned with the synthesizing of cu-zn nano-ferrite particles in the laboratory applying simple techniques. the morphology of the synthesized nano-particles was analyzed using transmission electron microscopy (tem), and the minerals were identified using x-ray diffraction (xrd). the nano material was used to replace 1- 4 percent by weight of portland cement in cement pastes and ...

the paper presents results of experimental studies on the methane and propane ignition process in various volumetric compositions of oxidizers heated to temperatures higher than ignition point of analyzed fuels (htac conditions–high temperature air combustion conditions). the increment of temperature dt and the ignition delay time tig are parameters characterizing the process of ignition under ...

nanotechnology has various applications in oil and gas industry such as enhanced oil recovery (eor). the main challenge in using nanoparticles in eor processes is their stability in harsh conditions such as high temperature, high pressure, and intermediate to high salinity. however, most of the recent experimental works have been performed under unrealistic conditions such as the use of distill...
