- چکیده:
- چکیده انگلیسی: Iranian youth presently forms third percent of the total population. The demographic ideals and behaviors of this proportion of population play the important role in demographic phenomenon and equations of the society. The present study has investigated some of the youth's socio-economic challenges and its denotation for marriage and childbearing ideals among the youth of Sanandaj city. The research data was raised from survey method that collected from 240 young persons aged 15-29 with a questionnaire. The analysis of the data is indicated that employment, monetary-economic problems, educations, marriage and the lack of clear outlook about future are the most important challenges of the youth in the region. Of course, these challenges were different according to people's demographic backgrounds and they are influential on their marriage and childbearing ideals too. Finally, in this regard, it has suggested that government and other involving organizations should be pace in removal of the youth's problems insistently and give the much attention and endeavor to this enormous stratum and valuable potency of the society.

- چکیده:
- چکیده انگلیسی: While a lot of Psychologists, Sociologists and Criminologists, have profound anxiety with regard to growth of harshness in streets and public places, the probability of ones get into attack in family is more than it. Violence against women is a kind of violent behavior related to sexuality that leads to hurt or perhaps ensue to physical, sexually and psychological damages.
The aim of this research is to study the domestic violence particularly violence against women among families of Dehgolan city(western of Iran). Research independent variables (social and familial factors) were deduced from social learning and social sources theories. According to Cochran sampling frame and multi-stage cluster sampling method were chosen about 245 of families and with questionnaire implement was collected intended information among couples.
In general information derived from 200 questionnaires was analyzable and this task was performed with SPSS software and with used of advanced statistics like Multiple Regression.
Analysis of data was indicating to confirmation of research's hypothesis with high degree of confidence. To detect of importance of independent variables for estimating dependent variable, multiple regression analysis reveals that variables including women's economic dependence, experience and observing violence by husbands in childhood, and weakness of social protections from women in society and family, explain 62 percent of variance violence against women. In addition, with regard to Standardized Beta, the variable of weakness of social protections and familial supports from women has had the most roles in explaining variance of dependent variable.- انتشار مقاله: 21-09-1389

- چکیده:
- چکیده انگلیسی: An efficient and accurate analytical solution is provided using the homotopy-Pade technique for the nonlinear vibration of parametrically excited cantilever beams. The model is based on the Euler-Bernoulli assumption and includes third order nonlinear terms arisen from the inertial and curvature nonlinearities. The Galerkin’s method is used to convert the equation of motion to a nonlinear ordinary differential equation, which is then solved by the homotopy analysis method (HAM). An explicit expression is obtained for the nonlinear frequency amplitude relation. It is found that the proper value of the so-called auxiliary parameter for the HAM solution is dependent on the vibration amplitude, making it difficult to rapidly obtain accurate frequency-amplitude curves using a single value of the auxiliary parameter. The homotopy-Pade technique remedied this issue by leading to the approximation that is almost independent of the auxiliary parameter and is also more accurate than the conventional HAM. Highly accurate results are found with only third order approximation for a wide range of vibration amplitudes.

- چکیده انگلیسی: BACKGROUND: The extensive consumption of milk and
dairy products makes these foodstuffs targets for potential
adulteration with financial gains for unscrupulous producers.
OBJECTIVES: The aim of this study was using PCR assay to
detect cow milk in labeled sheep milk, sheep yoghurt, and
Lighvan cheese (a traditional ripened cheese produced from
sheep's milk). METHODS: The assay utilized primers targeting
the mitochondrial 12s and 16s rRNA gene. In this study, 35
samples of sheep milk, 35 samples of sheep yoghurt, and 35
samples of Lighvan cheese were purchased from different
supermarkets in Mashhad city with different batch numbers.
RESULTS: The results showed only 21 out of 105 (20%) samples
contained pure sheep milk. Undeclared presence of cow and goat
milk was detected in 33(31.5%) and 68(65%) of the 105 samples,
respectively. CONCLUSIONS: It seems the PCR based analytical
method is an applicable technique to monitor adulteration in
dairy products.- انتشار مقاله: 01-04-1392

- چکیده:
- چکیده انگلیسی: In this paper, the multi-sensor fault diagnosis in the exhaust temperature sensors of a V94.2 heavy duty gas turbine is presented. A Laguerre network-based fuzzy modeling approach is presented to predict the output temperature of the gas turbine for sensor fault diagnosis. Due to the nonlinear dynamics of the gas turbine, in these models the Laguerre filter parts are related to the linear dynamic part of the models and the nonlinear parts of models are considered as neuro-fuzzy models. In order to deal with the dimensionality problems associated with fuzzy models, the nonlinear parts of models are considered as hierarchical fuzzy systems. In the residual evaluation phase, model error modeling adaptive threshold approach is used to increase fault detection robustness against the noise and disturbance. A new expert fuzzy system by multi-sensor information fusion is presented for the fault diagnosis system, which can examine the performance of all the sensors simultaneously. The result shows that the proposed fault diagnosis system could considerably increase reliability and safety.

- چکیده:
- چکیده انگلیسی: Objective(s): Escherichia coli is the key pathogen in the family producing ESBL (extended spectrum β-lactamase) and associated with community-acquired infections. Therefore, this study was planned to determine the antibiotic susceptibility pattern of uropathogenic E. coli, prevalence of the ESBL gene group and class 1 integrons.
Materials and Methods: Clinical isolates of uropathogenic E. coli were isolated from different hospitals of Karachi. Antibiotic susceptibility test was performed by Kirby-Bauer Methods. Presence of β– lactamases genes (CTX, TEM, and SHV) and integron 1 were identified by polymerase chain reaction (PCR).
Results: Out of 500, 105 isolates were identified as multi-drug resistant (MDR) uropathogenic E. coli. The subject MDR isolates showed the highest resistance to aztreonam, amoxil/ clavulanic acid, ampicillin, cotrimoxazole, ceftriaxone, cefipime, and cefuroxime. Genetic analysis showed that the majority of the MDR E. coli carry CTX M1 (57.1%) followed by TEM (33.3%) and SHV (9.5%). Moreover, 79% of MDR E. coli harbored class 1 integrons, whereas all three conserved genes for class 1 integrons were present in 58% of MDR E. coli.
Conclusion: This study is helpful to provide information regarding the antibiotic susceptibility pattern, distribution ESBLs and class 1 integrons among uropathogenic E. coli.- انتشار مقاله: 12-10-1396

- چکیده انگلیسی: Introduction: The aim of the current study was to investigate positive thinking in Islamic spirituality and to develop a theoretical model based on Islamic view.Methods: The research method in this study was based on qualitative approach. The study used a content analysis design with a hermeneutic approach to collect and analyze the data. In order to do so, sacred texts especially holy texts (i.e. Quran and Ahl al-Bayt's performance and oral tradition) were reviewed through hermeneutic understanding.Results: Findings demonstrated that positive psychology in Islamic spirituality mostly centers on the following topics: Islamic positive view of human, believing in Divine benevolence, gratitude, Tawakkul, and universal man. Also, based on the attachment theory, positive thinking was interpreted and its applications were explained for individual's thinking about past events, interpretations of present events, and future expectations. Positive thinking in this paradigm was discussed in a way that included individual's relationship with transcendental beings, others, nature, and self.Conclusion: The Islamic approach is very optimistic about human nature and its capacity for growth. It is also optimistic about the relation of human beings with God. The fourfold relational paradigm of positive thinking in Islamic spirituality has been accepted as a base for all relations. Approaching this paradigm and orienting thoughts, feelings, and actions towards this view may be achieved through an ontological gnostic worldview. Keywords: Attachment, Fitrah, Islam, Positive Thinking, Model
