ABSTRACTBackground: There are relatively rich uranium mines in regions of Saghand and Bafgh in Yazd province. This survey was carried out to provide a map of ambient gamma radiation of Yazd province and the probable effects of the existence of these mines on background radiation dose rates.Materials and Methods: The measurements of the outdoor and indoor–environmental exposures (including cosm...

Introduction: Background radiation is originated from environmental radioactive sources cosmicandterrestrial.Materials distribution onsurface of the earth and height from sea level are not the same at various points.Absorbed dose caused by them were different at various points.In this research, Background radiation level inoutdoor different areas of Ilam province was measured and effective dose...

the ability of subminimum inhibitory concentrations (sub-mics) of antibiotics to affect the virulence factors of bacteria may be an important criterion in selecting an antibiotic for therapy. proteus mirabilis is one of the most frequently seen pathogens in urinary tract infections. the aim of this study was to analyze the effects of some antibiotics on two important virulence factors of p. mir...

Concentrations and distributions of cadmium, copper, and lead in soils from several industrialized urban areas of Beijing, China were investigated. The mean concentration of Cd in surface soils was not significantly greater than the regional background concentration, while those of Cu and Pb were significantly greater than regional background concentrations. All soil profiles exhibited a decrea...

There is concern that visitor-use associated activities, such as bathing, dish washing, wastewater production, and stock animal use near lakes and streams, could cause degradation of water quality in Yosemite National Park. A study was conducted during 2004-2007 to assess patterns in nutrient and Escherichia coli (E. coli) concentrations in the Merced and Tuolumne Rivers and characterize natura...

all living organisms are exposed to ionizing radiation comprising cosmic rays coming from outer space, terrestrial nuclides occurring in the earth’s crust, building materials, air, water and foods and in the human body itself. the exposures are constant and uniform for all individuals everywhere including the dose from ingestion of 40k in food. cosmic rays are, more intense at higher altitudes,...

We introduce a performance evaluation methodology called Perturbation Detection Rate (PDR) analysis for measuring performance of foreground-background segmentation. It has some advantages over the commonly used Receiver Operation Characteristics (ROC) analysis. Specifically, it does not require foreground targets or knowledge of foreground distributions. It measures the sensitivity of a backgro...

A common method for real-time segmentation of moving regions in image sequences involves “background subtraction,” or thresholding the error between an estimate of the image without moving objects and the current image. The numerous approaches to this problem differ in the type of background model used and the procedure used to update the model. This paper discusses modeling each pixel as a mix...

Résumé. Ce papier présente notre méthode de conception de bases de données multidimensionnelles (BDM) contraintes. Nous proposons une méthode mixte basée sur une démarche descendante et une démarche ascendante. La démarche descendante est composée de trois étapes: la collecte des besoins des décideurs, la spécification et la formalisation de ces besoins suivant un modèle multidimensionnel en co...

Here, we report a draft genome sequence of Saccharomyces cerevisiae strain Kagoshima no. 2, which is used for brewing shōchū, a traditional distilled spirit in Japan. The genome data will facilitate an understanding of the evolutional traits and genetic background related to the characteristic features of strain Kagoshima no. 2.
