CBR as a strategy within community development for rehabilitation, equalization of opportunities, and social inclusion of all people with disabilities. The purpose of the study was Designing Community Based Rehabilitation Model using SEM. This study is a comparative-descriptive research that has been performed by factor analysis method. In the qualitative stage the process owners were 45 experts and in factor analysis stage, there were 564 CBR experts of Iran, CBR departments and rehabilitation deputies of 31 provinces and the CBR specialists and rehabilitation deputies of the CBR executing counties. The data collection tool was researcher-made questionnaire the content validity of which was determined through expert panel and its construct validity was determined through exploratory factor analysis by principal component analysis method with varimax rotation using SPSS16 software. Its reliability was also confirmed by test-retest and internal consistency method using Cronbach's Alpha (96%) and the most important community-based rehabilitation factors were identified through path analysis and structural equation modeling using LISREL software 8.8. In exploratory component analysis, 7 main components were identified; using semi-professional people with 9 variables, 43.1% variance, and 23.28 eigenvalue as the most important factor and social integration of the disabled people with 2 variables and 2.19% variance as the less important factor clarified the community-based rehabilitation changes; however, in the fitted model which is the most complete saturated model, 7 factors of subsistence with ß= 0.20, using semi-professional people with ß= 0.19, medical procedures with ß= 0.19, socio-political supports with ß= 0.18, social integration of the disabled people with ß=0.18, educational measures with ß= 0.16, and health practices with ß= 0.14 had the highest predictive power in the order of importance. Considering the cultural, economic, political, and social context of Iran, usage of the obtained factors can promote the dignity of the disabled people and their family in the society as well as empowering and equalization of their opportunities.

The present paper is concerned the second-order differential equation ,(*) with Neumann boundary conditions. By using the asymptotic solutions we find the distribution of eigenvalues of (*) in two turning points.

This study investigated the effect of the integrating currents issues of interest into class materials on the students’ achievement in learning grammar. The following question was proposed. Is relating current issues of interest to class materials useful on students grammar learning? It was hypothesized that integrating current issues of interest with class materials in teaching grammar has a positive effect on learning grammar. The study was performed at Islamic Azad University in Hidaj with 60 participants--male and female-- who were majoring in ‘mechanical’ and ‘electrical’ engineering. Since the researcher did not have the possibility of randomizing the subjects, 60 students of two classes who were taking their first semester at university were used for this study; one of the classes as the control group and the other as the experimental group. As Farhady (1995, p. 146) contends: “In classroom research it is unreasonable to expect the director of the courses to randomly assign students to classes for the sake of experimentation.” The subjects were taught for five weeks and finally took an achievement test. After analyzing the results of the test, and by comparing the means of the scores using t-test, it was found that integrating current issues of interest with class materials in teaching grammar lessons did not significantly improve students achievement in learning grammar.

Type 2 diabetes(TIIDM) aging-related disorder, is caused by a combination of peripheral insulin resistance and ?-cell dysfunction .Recent evidence, however, suggests that TIIDM is additionally characterized by impaired ?-cell regeneration and reduced ?-cell mass .Shortened telomeres have been previously associated with diabetes in several small-scale studies(Zhu et al.,2011). Measurement of telomere length in diabetic patients in different age and different duration of disease and compared with control. Also included the comparison telomere length between male and female for both control and diabetic groups and between patients from genetic origin (mother origin or father origin) and patients from non genetic origin. Genomic DNA was prepared from whole blood extraction using genaid kit and was quantified by Nanodrop .Terminal restriction fragment (TRF) lengths were measured using the Southern-blotting technique .This study was conducted between November 2010- November 2012 and, it was carried out at the diabetic Centre / Merjan Teaching Hospital in Babel Province by taking 54 diabetic patients(Type II DM) with disease duration (0-5),(>5-10 )and (>10 )years ,with age average (35-65 year)and most of them were on oral hypoglycemic drugs. While the study included 18 people apparently healthy that included 9 male and 9 female with age average (35-65 year). The study revealed that telomere length(TL) were differences between males and females of control group. Age- adjusted telomere length were shorter in males than in females of control subjects (13,200 bp ) vs. (11,600 bp), (14,200 bp) vs. (13,000 bp) and (15,100 bp) vs. (13,800 bp),and this differences in TL between males and females decreased as aging increased, while this gender differences in TL was not observed among the diabetic patients .In both the controls group and diabetic subjects, the telomere length were shorter in older subjects than younger for both males and females.

Abrus precatorius Linn. (Fabaceae) is a climbing shrub widely distributed in most of the districts of the country in hedges and among bushes on open lands. The objective of this work is to evaluate and compare anthelmintic activity of ethanolic extract of red seeds of Abrus precatorius. Earth worms were used for anthelmintic activity. Albendazole was used as standard drug. Time required for paralysis and death of animals were noted for each sample.

Background: The hypothalamic/pituitary/gonadal (HPG)axis is central to the mammalian reproductive system. Pulsatile release of GnRH from neurons in the hypothalamus stimulates the secretion of LH and FSH from gonadotropes in the anterior pituitary. It has long been recognized that reproductive function is closely associated with energy balance, and metabolic dysregulation is linked with reproductive abnormalities (Lu et al.,2008). Compare the differences in levels of adiponectin, FSH, LH, testosterone and estradiol between the diabetic patients and control group and in diabetic patients according to the durations of disease for both males and females groups .Also study the relationship between adiponectin and hormones for both gender and for both diabetic groups and control also in diabetic patients according to the durations of disease. The statistical analysis of this study showed that patients with Type 2 diabetes of both males and females had significantly lower in adiponectin levels than control group (P<0.05),but this level of adiponectin significantly higher in females than males for both diabetic groups and control (p<0.05) ,while the levels of FSH and LH had significantly higher in diabetes group than control (p<0.05) ,also significantly higher in females than males for both diabetic groups and control (P< 0.05). The result of hormonal analysis show there were no significant differences in estradiol and testosterone between diabetic groups and control (p > 0.05). According to the durations of disease, the results show significant elevation in adiponectin level in third duration of disease for both males and females groups as compared with first and second duration (P <0.004), while the levels of FSH, LH ,estradiol and testosterone show no significant differences among duration(P>0.05).

This paper reviews their contributions to knowledge of soil microbial diversity.

In this project we applied five data mining algorithms using Weka Tool (Data Mining Program) cases of monthly financial data of firms in the different sectors. These datasets have five years’ experience between2007–2012. After we applied these algorithms at these datasets, we displayed the results and compared the results that found by using these different algorithms.

Among the different strategies for teaching reading comprehension, graphic organizers have received much attention by many researchers and practitioners. This study investigated the effects of graphic organizers on Iranian EFL learners’ reading comprehension. Fifty male 3rd-year high school EFL learners were selected by means of the TOEFL test. They were divided into 2 groups of 25 homogeneous students: one experimental group and one control group. Participants were given a reading comprehension test before the treatment. Subsequently, the experimental group—Group A—received the graphic organizers intervention, and the control group—Group B—received a traditional reading instruction (translation-based). After an eight-week treatment, both groups were given the reading comprehension test again as a posttest. Statistical analysis showed a significant difference in the reading comprehension of the experimental group. It was concluded that the use of graphic organizers had positive effects on the L2 learners’ reading comprehension.

This paper suggests a new exponential ratio-type estimator for estimating the population variance using information of two auxiliary attributes in SRSWOR based on the adaption of the estimator presented by Lu et al. (2014). Problem is extended to the case of two phase sampling. The expressions for the mean square error of the proposed estimator have been derived. The proposed estimator has been compared theoretically with the usual unbiased estimator, usual ratio type estimator, estimator proposed by Chauhan et al. (2009) and the estimator proposed by Singh et al. (2009) and the conditions under which the proposed estimator are better than some existing estimators have also been given. An empirical study has also been carried out using two population data sets to demonstrate the efficiencies of the proposed estimator.
