An evaluation of the risk to an exposed element from a hazardous event requires a consideration of the element’s vulnerability, which expresses its propensity to suffer damage. This concept allows the assessed level of hazard to be translated to an estimated level of risk and is often used to evaluate the risk from earthquakes and cyclones. However, for other natural perils, such as mass moveme...
these advantages will not be fully recognized unless the spatial and temporal predictability of process-based Spatially averaged soil erosion data provide little information on models are validated. Thus, spatially distributed erosion soil erosion dynamics. Dynamically varied, spatially distributed erosion data are needed to better understand erosion processes and data are of great importance i...
Background and Objectives: Considering importance of food habits and possible roles of obesity in tooth decay, the present study was carried out to investigate relationships between dietary habits and body mass index (BMI) withtooth decay in 4–6 years old kindergartenchildrenin Ahwaz, Iran. Materials and Methods: In this descriptive-analytical study, 359 children were selected randomly from ...
Today, soil erosion is considered as one of main subjects of watershed management at national and global levels. Assessment of decreasing risk of soil and it spatial distribution are one of key factors for successful evaluation of soil erosion. The objectives of research were calculation and modeling of rain erosivity factor in Ilam province using data of number of 28 pluviometry stations durin...
