Background: In most industries, employees are in contact with various chemical agents. The objective of this study was to assess the health risks posed by occupational exposure to harmful chemical agents in a pesticide manufacturing plant in Zahedan, Iran, in 2013. Materials and Methods: This cross-sectional study was conducted in different units of a pesticide manufacturing plant. In order to...

Background: Chemical contaminants present in the work environments include gases, vapors, and solid and liquid suspended particles. The number of factories producing chemicals has increased significantly. Each year, new products are introduced into the market. Consequently, the number of employees at risk of exposure to these materials is increased. Hazardous chemicals are used in the petrochem...

conjunctive use of ground and surface water can increase reliability of the water supply by providing independent sources. in this study, corrected utility-efficient pro-gramming that allows for more than one seasonal irrigation depth for each crop was used to determine the amount of utility maximizing investment in the well capacity for conjunctive use. results showed that optimum investment a...

at early stages of new product development, the effort tooptimize is low and effects on the whole innovation process are high.therefore, a deeper understanding of fuzzy front end and its successcan help firms to be more successful in developing new products. wepresented and tested a conceptual model of relationships among keyvariable sre lated to the fuzzy front end,execution phase of new produ...

A key concept in model selection is to understand how model complexity can be modified to improve in generalization performance. One design alternative is to increase model complexity on a single global model (by increasing the degree of a polynomial function); another alternative is to combine multiple local models into a composite model. We provide a conceptual study that compares these two a...

The goal of this paper is to investigate the interaction between social ties and deceptive behavior within an experimental setting. To do so, we implement a modified sender-receiver game in which a sender obtains a private signal regarding the value of a state variable and sends a message related to the value of this state variable to the receiver. The sender is allowed to be truthful or to lie...

Aim: to study the factors leading adverse perinatal outcomes allowing, on this basis, predict degree of risk. Materials and Methods.
