The article presents a method for creating territory erosion hazard integrated map using RUSLE integral model, Earth remote sensing data and GIS technologies. studies carried out on this topic are presented, the analysis of which has shown more active use indicators water-erosion processes in foreign scientific works. Urgency updating methodology studying been substantiated. Theoretical foundat...
the radionuclides 226ra, 232th and 40k concentrations measured as well as radiological parameters, for 14 granite samples that use in iran as building material were calculated. the measurements of the radioactivity concentrations were carried out at nuclear physics laboratory university of tabriz. this subject is important in environmental radiological protection, since granites are extensively...
Background and aims:Toxic chemical release from process installation is one of the main hazards in chemical industries which can endanger the health of employees and public in the neighbours of industry in case of occurring chemical release accident. The aim of this study was determining hazard distance of toxic chemical release in one of petrochemical complex for its applicability in emergency...
Erosion is a major threat for coasts worldwide, beaches in particular, which constitute one of the most valuable coastal landforms. Vulnerability assessments related to beach erosion may contribute to planning measures to counteract erosion by identifying, quantifying and ranking vulnerability. Herein, we present a new index, the Beach Vulnerability Index (BVI), which combines simplicity in cal...
The aim of this study was to evaluate the prevalence, clinical manifestations, and etiology of dental erosion among children. A total of 153 healthy, 11-year-old children were sampled from a downtown public school in Istanbul, Turkey comprised of middle-class children. Data were obtained via: (1) dinical examination; (2) questionnaire; and (3) standardized data records. A new dental erosion ind...
Wind erosion is one of the environmental problems worldwide, particularly in arid and semi-arid areas of Iran. Different methods and models have been proposed to measure and monitor wind erosion in the recent years. One of the accurate models for measuring f wind erosion is the USEPA model. The purpose of this study was to evaluate the quantification of wind erosion with the USEPA model and the...
هدف از اجرای این طرح بررسی محیط زمین شناسی شهر زاهدان و تعین زمین شناسی زیست محیطی شهر جهت رفع مشکلات مربوط به بلایای طبیعی و الودگی ها می باشد.
Rainfall erosivity is one of the major factors of soil erosion that expressed as some indices. The objective of this study is to determine the appropriate rainfall erosivity index in West Azarbaijan in relation to soil loss at the erosion standard plates. After recording the rainfall amounts in a certain time periods, erosivity indices calculated and appropriate index was selected for the area....
BACKGROUND Neither clinical prediction models nor noninvasive imaging tests that detect coronary artery calcification identify all patients who experience acute coronary events. Variations in culprit plaque morphology may account for these inaccuracies. METHODS AND RESULTS We compared the 10-year Framingham risk index, histologic coronary calcification, and culprit plaque morphology in 79 con...
