Objective: In this study, psychometric qualities of multidimensional perfectionism scale (MPS) were evaluated. Methods: Persian version of perfectionism inventory was completed by 48 adults (24 females and 24 males). The sample was selected by cluster random sampling from Sarcheshmeh adult inhabitants. Reliability of the scale was assessed by calculating Cronbach's alpha coefficient. Then 26...
Background and Aim: Coronary angiography (CA) is a diagnostic and therapeutic procedure for cardiac complexity, that has a high dose and high fluoroscopy time. The effective dose of eye lens as a radiosensitive organ in long-term exposure to CA must be evaluated. Materials and Methods: A cross-sectional study was performed with Siemens under-bed machine in Imam Hossein Hospital of Mehran, Ilam...
Object-oriented load flow modeling is presented for both radial and weakly meshed distribution systems. An OO algorithm based on the Newton–Raphson technique is proposed. In the object oriented formulation, some approximations to the full Jacobian matrix are introduced. Consequently, a detailed study of the convergence characteristics of the proposed object oriented algorithm is presented and s...
in data envelopment analyze (dea) the scale efficiency in the input-oriented ccr model is less than or equal to the scale efficiency in dea based on the fractional analysis (dea-r). also, the scale efficiency in case of multiple inputs and one output and vice versa the scale efficiencies are equal in dea and dea-r. in this paper, first, dea-r model with weight restrictions when there is relativ...
Purpose: This research aims to investigate methods of identifying efficient provinces in terms of public library administration and to offer macro policies that dominate their management through the survey of efficiency trends of libraries dependant on public libraries Institution. Methodology: The research has used an analytical-descriptive Methodology. Data from the libraries of 30 provinc...
