Abstract: The present study aimed at finding the relationship of religious orientation (RO), psychological well-being (PWB), and self-esteem (SE) with language achievement (LA) among Iranian EFL learners. Furthermore, it investigated the predictability of dependent variable (LA) using all independent and predictor variables (RO, PWB, and SE). 126 senior and junior students majoring in English Translation and English Literature at Shahid Bahonar University of Kerman participated in the study. To obtain the required data, three questionnaires were utilized: Allport and Ross’s (1967) Intrinsic-Extrinsic Religious Orientation Scale (IEROS) to measure extrinsic and intrinsic religious orientations, Short Measurement of Psychological Well-Being by Clarke, Marshall, Ryff, and Wheaton (2001) to measure psychological well-being, and finally, The Rosenberg Self-Esteem Scale by Rosenberg (1965) to assess self-esteem. Moreover, participants’ GPAs in major courses were used as indicators of their language achievement. For analysis of data, Pearson Product Moment Correlation and Regression analysis were used. The results revealed that there was a significant positive relationship between IRO, PWB, and SE with LA and a significant negative relationship between ERO and LA. Additionally, all the independent variables together could predict LA and accounted for 95 percent of variability of students’ GPA.

Abstract: Entanglement of tripartite spin states under Lorentz transformations is studied in the context of Bell’s inequality and positive partial transpose criterion. First the relativistic analogue of Bell’s inequality is discussed for three qubit states by explicit calculation of the Wigner rotation. We use the relativistic invariant spin operator which is related to the Pauli-Lubanski pseudo vector. For observers at rest the Bell’s inequality is speed-independent and maximally violated. For moving observers it’s shown that Bell’s inequality is violated and the amount of violation depends on the boost speed. We show that in ultrarelativistic limit Bell’s inequality is still maximally violated. We also obtained the critical value for satisfying Bell’s inequality. The critical value of boost speed for violation of inequality for particles moving in the center of mass frame is greater than that for particles moving with the same momentum. Second we investigate the entanglement distillability of tripartite mixed spin states under Lorentz transformations in the context of Werner states. We show that there are states that will change from distillable (entangled) into separable for a certain value of rapidity.

Open Journal of Ecology (OJE) , 2015, DOI: 10.4236/oje.2015.53007
Abstract: Design of greenways is one of the most important planning tools in the promotion of quality of life of the city residents. Greenways are necessary due to their major role in increase of air quality and positive changes in the climate of the urban environments for keeping the environmental quality of the cities and considerably increasing aesthetic values of these environments. Protection of natural ecological systems, provision of extensive recreational opportunities for people in urban regions and rural districts, provision of economic benefits and protection of cultural values and historical heritage are the advantages of designing and creating greenways inside cities. The present paper which was conducted with descriptive-analytical method tried to explain design dimensions of ecological greenways in three urban physical, environmental and social-economic systems by studying suitable experimental concepts and samples in the world. In this regard, this paper studied five main goals of designing greenways: promotion of local and urban accesses with greenways, aesthetic aspects of urban landscapes, improvement of performance and distribution of activities by creating greenways, increase of efficiency and environmental aspects in the city and revival of social values considering economic sustainability and in this regard design strategies and policies were presented for each one of them based on these goals.

Urology Journal , 2006,
Abstract: Introduction: We reviewed the long-term outcome of substitution urethroplasty with skin flaps for anterior urethral strictures, comparing 1-stage with 2-stage repairs. Materials and Methods: A total of 45 patients with urethral strictures, 2.5 cm or longer, had undergone skin flap urethroplasty. A 1-stage surgical operation had been done in 10 patients (Orandi and bilateral pedicle island of penile skin) and a 2-stage surgical repair had been performed in 35 using the Johanson technique. They were followed up by retrograde urethrography for 1 to 10 years. Results: The mean age of the patients was 46.3 ± 17.1 years. Etiology of the stricture was instrumentation in 33.3% of the patients, urethritis in 28.9%, trauma in 13.3%, and unknown in 24.5%. At the first postoperative year, the success rate was 75.6%. This rate was 71.4% and 90% for the 1-stage and 2-stage operations, respectively (P = .23). There were 1 (10%) and 10 (28.6%) cases of recurrent structure and 1 (10%) and 3 (8.6%) cases of fistula in the patients with the 1-stage and 2-stage operations within the first year, respectively. During the 5 postoperative years, 70% of the patients with the 1-stage repair, 57.1% with the 2-stage repair, and 60% in total had no complications. Conclusion: Based on the previous studies and our experience, we recommend skin flap urethroplasty. However, some measures such as proper tailoring of the flap and the extension of the incision onto the intact segments should be considered for achieving a better outcome.
Oscillation phenomenon of transition temperatures of coupled magnetic planes
H. Moradi
Iranian Journal of Physics Research , 2004,
Abstract: Oscillatory behavior of transition temperature in supper lattice, Ni/Au/Ni, has been observed as a function of spacer layer, Au. The observed oscillation period is almost the half period of interlayer exchange coupling. The high temperature susceptibility of a two - dimensional lattice is evaluated within the Bethe-Peierls-Wiess approximation in the presence of a random field with square distribution. This susceptibility is used to evaluate the transition temperature of coupled planes as a function of spacer thickness. The calculated transition temperature of coupled planes oscillates as half period of interlayer exchange coupling and falls below the results of the uncoupled films at some values of the average spacer thickness that were experimentally observed. Additionally, the transition temperature depends on the distribution function of random field at the small thickness of spacer.
