Background: There is no doubt that one of the effective factors in implementation of projects that have potential hazard can cause irreversible losses. Therefore recognizing potential hazards is of paramount importance. Method: The present descriptive-analysis study was conducted at Rudbar Lorestan Dam constructional projects. For recognizing potential hazard in tunneling activities, job sa...
Background: Thirteen (13) types of building tiles and Sharp sand commonly used for building purposes were collected for their radionuclide contents analysis. Both imported and locally produced building tiles were examined. Materials and Methods: The samples of tiles and sand were crushed to powder and they were prepared such that their content could be examined by the use of gamma-ray spectrom...
heat stress is a common occupational health hazard at outdoor workplaces especially in a hot-humid climate. overheating of the body can cause a number of problems, including heat rash, heat cramps, dizziness, heat exhaustion, and heat stroke. the present study aimed to assess heat stress indices including di, wbgt, and sw req /phs, as a mean to estimate the heat load on the employees of a petro...
We propose an estimator of conditional wage distributions that is based on a piecewise-linear specification of the conditional hazard function. Under a minimal set of assupmptions, the estimator is flexible enough to capture almost any underlying relationship. It is not affected by the curse of dimensionality and allows to derive conditional Lorenz curves and Gini indices. The methodology is ap...
Abstract Hazard maps are essential tools to aid decision makers in land-use planning, sustainable infrastructure development, and emergency preparedness. Despite the availability of historical data, there has been no attempt produce hazard for Kuwait. In cooperation with World Bank, this study investigated natural anthropogenic hazards that affect The objective was assess face Kuwait map most c...
Background and Objective: Exposure to chemicals such as heavy metals can be occurred through the route of drinking water consumption. Chromium is an important pollutant because of its role in the appearance of carcinogenic and non-carcinogenic health effects in humans. In this study, we studied the carcinogenic risk and non-carcinogenic hazard of chromium due to the consumption of bottled drink...
Concerns about dust contamination with potentially toxic elements are especially important in environments such as schools (particularly elementary schools) because children are more vulnerable to contaminants than adults. Therefore, due to the diversity of air pollution sources in Tehran, the present study was conducted to determine the severity of pollution, origin and health risk assessment ...
BACKGROUND The association of overweight/obesity with the incidence of cardiovascular diseases, especially stroke, has not been comprehensively examined in relatively lean populations in which stroke is more prevalent than coronary heart disease. METHODS AND RESULTS Pooled individual data from 16 Japanese cohorts comprising 45 235 participants ages 40 to 89 years without previous history of c...
The authors present an assessment of risk from river bank erosion in the Brahmaputra river basin. The concept of risk is conceptualised in the context of socio-economic vulnerability, and the potential for exposure to hazard. By addressing both the physical hazard and the variations across the socio-economic surface the approach presented attempts to spatially combine these parameters to provid...
abstract the variables affecting the nature of reading comprehension can be classified into two general categories: reader’s variables, and text variables (alderson, 2000). despite the wave of research on vocabulary knowledge as reader’s variable, the role of this knowledge in c-test as a text-dependent test and its interaction with lexical cohesion of the test as a text feature has remained a...
