Objective: Income inequality affects consumption structure via changes in the composition of expenditure basket. Shocks, fluctuations, disparities, and dispersions of income inequality, is expected to be transmitted to consumption expenditures. These shocks might induce inequalities in consumption expenditures. This paper tries to measure the amount of such consumption expenditures inequal...
to follow-up the present study, 40 mature female rats were used. the animals were divided into test,control and sham groups. the rats in the test group were laparotomized and unilateral ovariectomy was done. on the 1st and 2nd met-oestrous after operation, the tissue samples were dissected out and processed for histological study. the intact ovary in the test group underwent a significant (p
iran is located in an area with high earthquake risk. there are over 20 active faults with length of 500 km and also densely populated parts of the country have been rendered vulnerable to strong earthquakes. however, existence of eight faults of the main faults of iran along with at least 18 faults with length of more than 100 km in kerman province have turned the place into one of the riskies...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...
the present study is based on the assumption that the more the women enjoy the cultural capital, the higher their position in the power structure of the family and the more their bargaining power will become. for evaluating the aforementioned theory, the required data were attained through survey methodology and questionnaire tool and a sample size of 385 married women residing in shiraz was se...
هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
The stochastic data envelopment analysis (SDEA) was developed considering the value ofinputs and outputs as random variables. Therefore, statistical distributions play an importantrole in this regard. The skew-normal (SN) distribution is a family of probability densityfunctions that is frequently used in practical situations. In this paper, we assume that the inputand output variables are skew-...
A multi-objective heuristic particle swarm optimiser (MOHPSO) based on Pareto multi-objective theory is proposed to solve multi-objective optimality problems. The optimality objectives are the roof displacement and structure weight. Two types of structure are analysed in this paper, a truss structure and a framework structure. Performance-based seismic analysis, such as classical and modal push...
the existence of some geometrically imperfect members, like initial curvature in a double layer space structures with hundreds or thousands of members is almost inevitable. these imperfections give rise to loss of load bearing capacity of double layer space structures. to evaluate the effect of initial member imperfection on load bearing capacity of double layer space structures and their failu...
