on- the-job training on of the most effective tools for managers to cope with the changing organizational environment. it grantess suitable services to customers, particularly in public service enterprises. if such training os goal oriented, planned systematically, and tailored to the employees, job content, then not only it could increase employees and organizational performance, but also it c...
performance evaluation of universities is an important issue between researchers. classic data envelopment analysis (dea) models with deterministic data have been used by many authors to measure efficiency of universities in different countries. however, dea with stochastic data are, rarely used to measure efficiency of universities. in this paper, input oriented model in stochastic data envelo...
nowadays, electricity is one of the most significant infrastructures required for economic development of countries. hence, predicting electricity demand is very important especially in industry as a major electricity-consuming sector. the majority of studies under the subject of electricity demand have been performed by econometrics and it is not possible to investigate the effect of different...
Background and Objective: Microbial fuel cell (MFC) is a new green technology that uses the catabolic ability of microorganisms to produce bioenergy while simultaneously removing organic matter and other wastewater contaminants. Electrode material is one of the factors affecting the performance of microbial fuel cells. The aim of this study was to investigate the performance of microbial fuel c...
Background and purpose: Among the numerous chemicals utilized in agriculture, 2,4-Dichlorophenoxyacetic acid (2,4-D) is widely used to control weeds. This herbicide is considered as a carcinogen and high toxic pollutant which is very difficult to remove due to its biological and chemical stability. This study aimed at photocatalytic degradation of 2,4-D using indium oxide nanoparticles in the p...
the wepp physically model is able to dynamically simulate runoff and soil erosion using physical concepts of erosion and hydraulic of overland flow science considering plant growth, residue decomposition, winter process. determination of the capability of this model in runoff and erosion estimation in different range type with investigation the effects of management were the main objectives of ...
in the present study, the capability of dried indigenous biomass of vibrio and oceanimonas, was assessed and compared for mercury biosorption from aqueous solutions. it was found that both of the biosorbents reached equilibrium after 60 min of contact although the mercury sorption capacity of vibrio was significantly more. its sorption capacity increased from 9 to 83 mg/g biomass by increasing ...
Background and Objectives: Health insurance would guarantee people security against disease and health problems. Given the key role of health insurance in achieving the goals of justice and reducing the out-of-pocket payment, this study aimed to evaluate the performance of Iran health insurance using the DEA model in 2014. Methods: This was a cross sectional study. The study population inclu...
In this paper, a hybrid solid oxide fuel cell (SOFC) and micro gas turbine (MGT) power system is parametrically studied to evaluate the effect of different operating conditions. The SOFC/MGT power system includes SOFC reactor, combustion chamber, compressor and turbine units, and two heat exchangers. The effects of fuel utilization, temperature, and pressure are assessed on performance of t...
The exchange rate unification is one of the most important instruments of economic adjustment, which is used in many countries. This paper shows the effects of the exchange rate unification on price level (inflation), gross domestic production (GDP), non-oil exports, private conception, government expenditure and stock of money. The data, is used related to the period 1959-2000. To analyze the ...
