حقوق مالی انتقال (ftr) یکی از ابزارهای مالی برای پوشش ریسک بازیگران بازار برق در مواجهه با پدیده پرشدگی خطوط انتقال است. هر ftr از نقطه تزریق به نقطه دریافت تعریف می شود که این نقاط می توانند یک شین، ناحیه یا منطقه باشند. ftr که بین دو نقطه از شبکه (دو شین یا دو ناحیه) تعریف می شود، به دارنده خود این حق را می دهد که در صورت بروز پرشدگی در شبکه انتقال و ایجاد تفاوت در قیمت های برق در این دو نقطه...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
Background & Aims: Compliance with standards of designing information systems leads to efficient utilization and ease of use for consumers. In this study, the compliance of the radiology and pathology subsystems of a hospital information system with ISO 9241 section 12 was assessed in selected hospitals affiliated with Kerman University of Medical Sciences, Iran. Methods...
the purpose of this research is to evaluate the effectiveness of implementation quality management system (iso 9001:2000) in gas processing plants of national iranian gas company using balanced scorecard approach. more specifically, we chose the balanced scorecard framework to examine five well-known gas processing plants in national iranian gas company from four different perspectives in order...
We examined in a rabbit model of transient spinal cord ischemia (SCI) whether isoflurane (Iso) preconditioning induces ischemic tolerance to SCI in a dose-response manner, and whether this effect is dependent on mitochondrial adenosine triphosphate-dependent potassium (K(ATP)) channel. Eighty-six rabbits were randomly assigned to 10 groups: Control group (n=8) received no pretreatment. Ischemic...
this paper proposes an optimal transmission expansion planning (tep) which is based on determining share of each line in merchandizing surplus (ms) of system, determining by independent system operator (iso). the more share of a line in ms of system denotes the priority of a line for expansion. the procedure of determining ms of each line in a power system is based on determining the ms share o...
dft calculations were applied to evaluate the electronic and magnetic properties of zigzag bc2nnanotubes based on the 13c, 15n, and 11b nmr parameters and natural charge analysis. weconsidered three types of zigzag nanotubes, zz-1, zz-2, and zz-3 (n, 0) with n = 8, 12, and 14. theobtained results indicated the divisions of the electrostatic environments around c nuclei into a fewlayers, consist...
Gallium extraction from Jajarm Bayer process liquor (Jajarm, Iran) was investigated using microemulsions. Also the behavior of aluminum was studied as an impurity. Kelex100 (4-ethyl, 1-methyl, 7-octyl, 8-hydroxyquinoleine), iso-decanol and n-butanol, and kerosene were used as the surfactant, co-surfactant, and oil phase, respectively. Ternary phase diagrams were produced using various co-surfac...
This article seeks to identify the factors that have impacted the adoption of ISO 10303, the Standard for the Exchange of Product Data (STEP), within the UK Ministry of Defence. The analysis presented in this article is based on Diffusion of Innovation (DOI) Theory and the theory surrounding the Economics of Standards. Using a case study approach, the results indicate that several DOI and econo...
