Groundwater is one of the most important water resources in Fars province. Based on this study, 95 percent of the total annual water consumption in Fars is used for agriculture, whereas the percentages for domestic and industrial uses are 4 and 1 percent, respectively. Population growth, urban and industrial growth, and agricultural development in Fars have created a condition of water stress. ...

INTRODUCTION In this paper, we show that FARS data can be a comparable alternative to observational NOPUS data in estimating seat belt use in the United States once we correct for sample selection bias. RESULTS Based on assumptions of independence for seatbelt choice, we establish a lower and upper bound for seatbelt usage rates, and find that once we correct for sample selection bias, the se...

Objective – Public concern has arisen about the reliability of front airbags because Fatality Analysis Reporting System (FARS) data indicate many nondeployed airbags in fatal frontal crashes. However, the accuracy of airbag deployment, the variable in question, is uncertain. This study aimed to provide more certain estimates of nondeployment incidence in fatal frontal crashes. Methods – Fatally...

OBJECTIVE Public concern has arisen about the reliability of front air bags because Fatality Analysis Reporting System (FARS) data indicate many nondeployed air bags in fatal frontal crashes. However, the accuracy of air bag deployment, the variable in question, is uncertain. This study aimed to provide more certain estimates of nondeployment incidence in fatal frontal crashes. METHODS Fatall...

Recent studies have shown that certain man-made compounds (including some pesticides and herbicide) through interfering with endocrine system, have the capability to induce developmental and reproductive abnormalities in humans and animals. Pesticides are currently being used in large scales in many developed and developing countries (including Iran), so this study has been conducted to determi...

BACKGROUND Cancer is a major health problem in the developing countries. Variations of its incidence rate among geographical areas are due to various contributing factors. This study was performed to assess the spatial patterns of cancer incidence in the Fars Province, based on cancer registry data and to determine geographical clusters. METHODS In this cross sectional study, the new cases of...
