cotton as a strategic product plays an important role inthe economy of boshrouyehwhere is known as the major cotton producing center of khorasan-e-jonoubi. in this paper, efficiency of boshroyeh cotton farms in 2007 have been calculated using data envelopment analysis (dea) and determinants of efficiency were identified using tobit regression analysis. the data was collected from questionnaires...
This research analyses the efficiency of China’s banks using the data envelopment analysis (DEA). The Chinese government began its reforms of the banking industry reform since 1978. Our data set contains twelve banks in China during the period of 1996 to 2003. All nominal variables are transformed into real variables in the 2003 prices. There are twelve banks including four state-owned speciali...
in this project, 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid, was prepared by the reaction of trimellitic anhydride (tma) with 4,4?-methylenebis(3-chloro-2,6-diethylaniline) (mcdea). the novel poly(amide-imide) (pai) was synthesized from the reaction of 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid with mcdea under green condition using ...
introduction the high energy consumption is one of the serious problems in poultry industry. the poultry industry consume about five percent of total energy sources in different countries, with consideration of losses, it increases up to 16-20%. in the year 2003 also, the iranian chicken meat consumption per capita was 13.3 kg, while in the year 2013 it increased to 25.9 kg (fao, 2014). it show...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
savojbolagh is the main region of hydroponic greenhouse agriculture in iran and is of the capacity to produce the highest in greenhouse production strawberry. the aims followed in this study were to calculate the energy use pattern and determine the relationship between energy input in greenhouse strawberry production and its yield through a linear programming model as based on data envelopment...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
This study intends to estimate bias corrected efficiency, technical efficiency, managerial efficiency and thus scale and confidence intervals associated with them, using input oriented data envelopment analysis approach and LSW algorithm. Results show the average of scale efficiency of our country’s industry section is 93% and except for recycling industry (code no. 37), furniture and unclassif...
The main purpose of this research paper is to calculate Irans Housing (Maskan) Bank through the use of Data Envelopment Analysis. In this research, the performance of 33 branches of the Housing Bank throughout Tehran (capital city of Iran) within 2002-2004 was analyzed and discussed. The results of the study shows that average technical efficiencies of Housing Bank branches in two hypotheses of...
The aims of this study were to evaluate the energy consumption and its modeling in industrial milk production units using data envelopment analysis (DEA) approach and sensitivity analysis. Data were collected from 44 industrial milk production units in Guilan province of Iran with face to face questionnaire method during 2012-2013. Inputs included animal feed, fossil fuels, electricity, machine...
