Amin Amid, Somaye Moradi
Journal of Software Engineering and Applications (JSEA) , 2013, DOI: 10.4236/jsea.2013.65035
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.

Genetic variation of Garra rufa fish in Kermanshah and Bushehr provinces, Iran, using SSR microsatellite markers
Ali Shabani, Ghasem Askari,Amin Moradi
Molecular Biology Research Communications , 2013,
Abstract: Six highly variable microsatellite loci were used to investigate the genetic diversity and population structure of the Garra rufa in Kermanshah and Bushehr provinces, Iran. All of the 6 microsatellite loci screened in this study showed polymorphism. A total of 90 individual fish from 3 populations were genotyped and 60 alleles were observed in all loci. The number of alleles per locus ranged from 6 to14. The average allelic number of these polymorphic markers was 10. The averages of observed (Ho) and expected heterozygosity (He) was 0.529 and 0.826, respectively. The genetic distance values ranged between 0.235-0.570. The UPGMA dendrogram based on genetic distance resulted in three clusters: Gamasiab population alone was classified as one and the other two populations as the second cluster. This study revealed a fairly high level of genetic variation in the microsatellite loci within the three populations, and identified distinct population groups of Garra rufa. This study gains significance for the analysis of the populations’ genetic diversity as well as the management of this important fish resource.

Behzad Farahani,Mehrshad Poursaeid Esfahani,Mohammad Amin Abbasi,Farhad Moradi
Acta Medica Iranica , 2012,
Abstract: To explore the abnormalities in Iranian athletes' electrocardiogram and find any relation with body fat. 239 international athletes were involved in this cross sectional study. Body-fat percentage and resting 12-lead ECGs were recorded from all participants. Of 239 participant athletes, 212 were male and 27 female. 60% of participants had sinus bradycardia. A total of 84% of the athletes demonstrated at least 1 abnormal ECG finding. Average values for the PR, QRS and QT intervals, P-wave duration and QRS axis were in normal range. Frequencies of various ECG abnormal findings in all athletes were as follows: right axis deviation 4.2%, left ventricular hypertrophy 6.2%, sinus arrhythmia 5.8%, right bundle branch block (RBBB) 24.2% (incomplete RBBB 16.8%, complete RBBB 7.4%), ST elevation 72.5%, prolonged QT interval 1.7%, T inversion 3.1% and Mobitz type I 1.2%. The athletes' ECG response to treadmill stress test was normal with no ischemia or arrhythmia. The means of BMI and body-fat percentage were 24.04 ± 3.5 kg/m2 and 9.15 ± 2.12%, respectively. Pearson correlation coefficient between body-fat percentage and ST changes was 0.65 (P=0.008) in anterior leads and 0.198 (P=0.017) in lateral leads. Also, the correlation coefficient between the body fat percentage and right bundle branch block was 0.36 (P=0.013). The results of current study support the inclusion of ECG in athletes' cardiac screening before they engage in vigorous exercises in order to detect the potentially fatal arrhythmias.
Theory of Carbon Nanotubes as Optical Nano Waveguides  [PDF]
Afshin Moradi
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2010, DOI: 10.4236/jemaa.2010.212088
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.

Current Research Journal of Biological Sciences , 2012,
Abstract: There is no doubt that certain plants offer valuable medicinal properties. But there are many challenges that local communities face in the harvesting and cultivation of these plants. Medicinal pumpkin (Cucurbita pepo L. var. Styriaca) is an economically important medicinal plant cultivated for oil production. Water source limitation is one of the important problems in agriculture worldwide. Natural zeolits have some properties such as water absorption and emission and nitrate leaching inhibition, which is useful for soil amendment. This study was carried out to investigate the effects of zeolite and selenium application on some physiological traits and oil yield of medicinal pumpkin (Cucurbita pepo L.) under drought stress. A field experiment was carried out in a factorial based on a randomized complete block design with three replications. The factors included: Irrigation (control, drought stress imposed during at flowering phase and drought stress imposed during fruit formation), Zeolite (non-application and application of 10 ton/ha) and Selenium (nonapplication and 30 g/Lit) from sodium selenate. All physiological parameters were affected by drought stress and zeolite application. Drought stress decreased total chlorophyll content, stomatal conductance, RWC, leaf soluble protein, oil content and oil yield and zeolite application in drought stress increased mentioned traits except oil content. Proline accumulation, WSD and CAT antioxidant enzyme activity were reduced in presence of zeolite in drought stress conditions than under control. Selenium spraying with zeolite application in drought conditions increased RWC, CAT antioxidant enzyme activity and oil yield. Drought stress at fruit formation phase reduced oil content and oil yield more severe than that on flowering stage. Finally, it seems that zeolite and selenium application in dry lands are exposed to drought stress be helpful for physiological traits and oil yield improvement and prevention of decreased oil yield.
The Role of Religious Orientation, Psychological Well-Being, and Self-Esteem in Iranian EFL Learners’ Language Achievement  [PDF]
Elham Moradi, Jahanbakhsh Langroudi
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.
Tripartite Entanglement and Lorentz Transformation  [PDF]
Firouz Amiri, Shahpoor Moradi
Journal of Quantum Information Science (JQIS) , 2014, DOI: 10.4236/jqis.2014.43017
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.
