Abstract: Introduction: Appendicitis is a common urgent surgical operation. Since early diagnosis and treatment of appendicitis is necessary and also some disease mimic its clinical manifestation and rate of negative appendectomy was high (15-30%), so surgeons were trying to increase the accuracy of diagnosis of appendicitis by using laboratory facilities. The main aim of this study were to investigation of Sensitivity and Specificity CRP in the diagnosis of acute appendicitis and compare it with routine laboratory tests such as leukocyte count and neutrophil count.Material and Methods: In this descriptive - analytical study, blood samples of 191 patients with diagnosis of acute appendicitis that underwent appendectomy at the Besat hospital, were used to measuring of CRP. The surgical specimens were reviewed by pathologists and pathologic findings were considered as gold standard. Then by using of the results of pathology tests, sensitivity, specificity and positive and negative predictive value of CRP, WBC and neutrophils were measured. Data were analysed by SPSS-14 software and t test and chi square test.Results: 74/3% of patients were male and 25/7% female and the mean age was 26 ± 3/4 years. The most common symptom, sign and pathologic stage of patients were loss of appetite (95/2%), local tenderness (95/8%) and Acute suppurative (64/9%). 08/13% of patients had normal appendectomies that consist of 35% of women and 6% of men appendectomy. The sensitivity and specificity of CRP, WBC and neutrophils respectively were: 98/1%, 61/5%, 84/8%, 50%, 93/3% and 19.2%.Conclusion: According to the results, the CRP test at diagnosis and in finding of negative appendectomy has high value. But wasn't reliable as an exclusive test. Therefore, the use of CRP as a paraclinical criterion along with other criteria of Alvarado scoring system can be very useful in diagnosis of appendicitis.

Abstract: The propagation of surface plasmon waves in metallic single-walled carbon nanotubes is analyzed within the frame-work of the classical electrodynamics. The conduction electrons of the system are modelled by an in?nitesimally thin layer of free-electron gas which is described by means of the semiclassical kinetic theory of the electron dynamics. The effects of the energy band structure is taken into account and a more accurate dispersion relation for surface plasmon oscillations in the zig-zag and armchair nanotubes of metallic character is obtained.

Open Journal of Modern Linguistics (OJML) , 2013, DOI: 10.4236/ojml.2013.34043
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:

It is essential to study quality of software production like others. Software productions have special properties. They are intangible. So, qualitative evaluation encountered with complexity. Hence, proposing a model in order to evaluate the quality of Software productions is considerable to most software managers and experts. In this paper, regarding to improve software productions quality, the process of software production has been determined, using CMM standard framework of maturity level. In CMM it does not present a method for measurement and evaluation maturity level, the presented process in CMM standard mapped by COBIT control objectives has been combined in the process of software productions development in developed hybrid framework. In this research, the processes have been mapped utilizing focus and established group, in parallel of software production in different maturity level of CMM mapped by COBIT framework. In order to show the capabilities of proposed framework, the hybrid evaluation model was employed in a software developing organization as a case study. According to the results of evaluation, improvements proceedings and action plans have been proposed and discussed to enhance the software production processes.

Tripartite Entanglement and Lorentz Transformation  [PDF]

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.

Mohammadreza Pourjafar, Amir Moradi
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.

Journal of Intelligent Learning Systems and Applications (JILSA) , 2012, DOI: 10.4236/jilsa.2012.43023
Abstract: A conflict is an event in which two or more aircraft experience a loss of minimum separation. In this paper, we formulate the problem of solving conflicts arising among several aircraft moving in a shared airspace as a Constraint Satisfaction Problem (CSP). The constraint satisfaction problem being NP-complete, the algorithms developed to solve it have been of two types: non-systematic and systematic search methods. In this paper, we have considered a breakout algorithm as an example of non-systematic search methods and a backtracking procedure that maintains Arc Consistency (MAC) as an example of systematic search methods. The performance of these algorithms was compared experimentally and the Breakout algorithm is shown to be clearly superior.
Rockfall Hazard in an Old Abandoned Aggregate Quarry in the City of Tétouan, Morocco  [PDF]
Hatim Dellero, Younes El Kharim
International Journal of Geosciences (IJG) , 2013, DOI: 10.4236/ijg.2013.48116
Abstract:

Quarries are places of high instability due to blastings, if left without rehabilitation they become sites of great risk of rockfall, which are the case of the Carian quarry, a small abandoned aggregate quarry, which turned into a slum neighborhood in the north western part of the city of Tétouan, and that has a long history of rockfall incidents since it was shut down in the 60’s. Using rockmass characterization techniques, kinematic study and stability analysis, it was confirmed that many instability mechanisms are found on the walls of the quarry and cause a high risk of rockfall during the rain season, especially that the study area is inhabited. Rockfall trajectory modelling techniques allow the calculation of vertical distribution of rocks falling from the quarry’s walls along different profiles in the area and therefore the determination of a safety perimeter from the quarry wall.
