results significantly high levels of radon gas were found mostly in water and residential buildings. conclusions it conclusion with regard to the study of building materials, granite stone and adobe coverings cannot be recommended for construction purposes. materials and methods the most important route of exposure to such radiation is indoor places. in this investigation measurement of radon i...

hematological parameters are suitable biomarkers for evaluating the potential risk of the chemicals. the aim of this study was to investigate of acute crude oil exposure on basic physiological functions of persian sturgeon, acipenser persicus. 210 juvenile persian sturgeon (9.4 ± 1g) were supplied by the rajaei fish farm in mazandaran province, iran.  juveniles were exposed to the crude oil (15...

background:  the aim of the study was to estimate the radiation dose during emergency exposure to patients treated with iodine-131 during the isolation period. materials and methods: the dose rate from a sample of 192 patients administrated by three different radioactivity of 131i (3.7, 5.55 and 7.4 gbq) was measured, at 1 meter after 1, 24 and 48 hours post dose administration, at three differ...

This article describes the mechanisms affecting the thermal behavior of buildings. This behavior depends upon the temperature and humidity balance in premises. First the physical mechanisms of heat transfer are explained, followed by a description of the heat and humidity sources and sinks in premises. The next three sections deal with the physics of psychrometry, necessary for understanding th...

BACKGROUND The term "exposome" was coined in 2005 to underscore the importance of the environment to human health and to bring research efforts in line with those on the human genome. The ability to characterize environmental exposures through biomonitoring is key to exposome research efforts. OBJECTIVES Our objectives were to describe why traditional and nontraditional (exposomic) biomonitor...

We recently completed a review of scientific evidence, particularly epidemiologic evidence, regarding the contribution of environmental and occupational exposures to the overall cancer burden in the US. We evaluated the efforts to estimate the proportion of cancer due to these involuntary exposures, including the ambitious effort by Doll and Peto and an update by a group of authors at the Harva...

Soft X-ray microscopy is a powerful tool for investigations of, for example, polymers or soils in their natural liquid environment. This requires a wet-specimen chamber. Compact X-ray microscopy allows the horizontal mounting of such samples, thereby reducing the influence of gravitational forces. We have developed a wet-specimen chamber for such compact X-ray microscope. The chamber is vacuum ...

Revisions in the theoretical basis and practical applications of the Counting Method are described based on clinical and research experience with this technique, which aims to reduce intrusive traumatic memories. The importance of the role of imaginal exposure, rather than the therapeutic alliance, is emphasized, and the advantages of a more parsimonious, streamlined approach to exposure therap...

A composite material consisting of Bacillus subtilis spores suspended in a humidity sensitive hydrogel can be used to pattern biomolecules in different concentrations directly onto glass surfaces using a mechanical micromanipulator. By altering the relative humidity surrounding the composite gel during deposition, surface concentration of patterned biomolecules can be controlled and varied to c...
