Consumer behavior analysis is a fundamental issue in economics. The most prominent methodology that economists use to attribute preferences according to this principle is the revealed preference concept. Therefore, neoclassical utility function is capable to test the rational behavior hypothesis of consumer. In this paper, we formalize a method of revealed preferences in place of neoclassical utility function to test the hypothesis of rational behavior using the Iranian rural households’ consumption data over the period 1982-2005. According to results, we didn't detect any violations in the whole consumption data. But in agriculture commodities group, we detected 4 violations using generalized Afriat index ascribed to measurement error. overall, the findings of the study confirm the hypothesis of rational behavior. Thus, there exists a utility function that is non-satiated, continuous, monotonic, and concave that rationalizes the consumption data of rural households in Iran

Aims: Nylon or polyamide is one of the most used and most important polymers used in the plastic and fiber industries of the world. For this reason, its use is less sensitive to the properties of its very poor biodegradability. Therefore, the aim of the present study was the biodegradability modification of synthetic polyamide 6 (pa6) fibers via in-situ melt blending with recycled poly (lactic) acid plastic food container flakes (r-PLA) during the melt spinning process.
Materials & Methods: In this experimental study, polyamide chips 6 in textile industry and Poly (Lactic) Acid Plastic Disposable Container Flakes were used. The weight loss, mechanical properties, and surface morphology variations of pure and modified fiber samples after soil burial test were analyzed for comprehensive biodegradability study of the modified fiber samples. Data were analyzed by One-Way Analysis of Variance.
Findings: The mechanical tests performed on Norris fiber showed successful production of blend fibers with the percentages of 5, 10, 20, 30, and 40 of the components of r-PLA and A 50% r-PLA fiber sample did not have acceptable mechanical properties. The changes of PA6/r-PLA blended fibers with a significant increase in r-PLA component in the PA6 substrate were significant.
Conclusion: The blend modified of PA6 and Poly (Lactic) recycled samples, with a composition containing from 5% to 40% of the dispersed recycled poly-lactic acid fraction have successfully melt spinning capability. By increasing the percentage of recycled poly lactic acid in the blended fibers, the mechanical properties show improvement in samples of 5% and 10% by weight and show reduction in higher percentages. Iincreasing the biodegradability of modified PA 6 fibers with increasing the r-PLA content is obviously confirmed.

In after revolution penal law, especially Islamic penal code (note 1 from article 49), contrary to previous legislations, "religious puberty" age is determined as criminal age limit. In practice, penal authorities without producing a definition for the term "religious puberty", considere it equal to concepts inserted in civil code conforming to "sexual puberty" especially note 1 of article 1210 of that act. According to which, females of nine years old and males of fifhteen years old are considered criminally liable and punishable simillar to adults. But, in most of national legislations, principally minors under 18 years old have not criminal responsibility and if they commit a crime they are only expose to protective or correctional measures and other alternative actions that focus on rehabilitation of the minors. So, international human rights instruments such as infant convention and etc, have forbidden for minors under 18 years old using death and imprisonment penalties which are opposed to human right’s and have a negative impact on losing party. Also, in this provisions for the minimum threshold, it can not allowed the judiciary intervention and the application of sanction’s. Our evaluation shows Iran criminal policy about juveniles delinquent is contrary not only to international legislations and legislations of most countries of the world but also to all scientific criminal principles and rules from criminal sciences view point, especially criminology and psychology. Thus, present study tries to express through a comparative survey and analysis as far as possible the relevent short comings and the appropriate solutions.

Village, like any other human phenomenon, has undergone various processes of change. As a historical necessity in relation to human needs, villages have appeared, developed and continued to survive. In this process, some of the villages amalgamated with each other or merged into nearby cities or as the result of population increase they transformed into new cities. In the process, some other encountered change or reduction in natural resources; local natural disasters; changes in socio-economic and political condition; and local periods of decline and even total abandonment, as a result of population decrease and mass emigration. These villages were either totally eliminated from geographical maps or began to adopt a new life, much or farms. The villages of Iran followed the same path. During past fifty years they have been under the deep changes and disorders in their social, cultural, economic and physical dimensions. Since identification and assessment of the rural changes is a part of rural geography studies, geographers using different methods, to explain the process of change in village life. This article is an endeavor to address the following two questions: 1.By using “Life Cycle Theory”, to what extent one can provide a new method of study in rural geography? 2Dose the “Life Cycle Theory” have incidental capacity to explain the process of evaluation in village life? This article, by relying on descriptive – analytical method, intends to illustrate the capacity of this theory to generalize this process, from geographic point of view. The assessment carried out indicates, that in spite of few criticism and limitations. The “Life Cycle Theory” has a high capacity to define and analyze the process of village changes. Rural Geography by utilizing this theory can introduce an applicable methodology for studies of changes in village life in Iran.

Ti-6Al-4V alloy due to excellent mechanical properties mainly is used in the aerospace, automobile and biomedical industries. Electrical discharge machining (EDM) are used extensively for machining of this alloy. Due to the thermoelectric nature of this process, unwanted changes happen on machined surface such as development of residual stresses and the change in the corrosion resistance. The aim of this study is the experimental investigation of the effect of input parameters (discharge current and pulse on time) on the amount and distribution of residual stresses and corrosion resistance changes of the machined surface in EDM process of Ti-6Al-4V alloy. For this purpose, samples of Ti-6Al-4V alloy were machined by EDM process and residual stresses induced successive sparks in different setting (different discharge currents and pulses on time) were measured by nanoindentation method and SEM images of machined surface used to better assess of samples surface integrity. TOFL measurement method used to determine the corrosion resistance of the samples. Results indicate that at this process tensile stresses is formed on surface and mentioned stresses increase with depth initially and after reaching a maximum dropping out and eventually leads to pressure stress. By increasing pulse on time and discharge current, maximum tension residual stress only slightly increases and is near ultimate tensile strength of work piece material. Comparison of corrosion results indicated that the corrosion resistance of EDMed samples, was less than the not machined specimens.

Quality is a concept that is based on the views of users, users needs and dominances is established. Thus, among the various groups of users have different meanings. statistics Data quality to the appropriate degree of confidence in them to meet the needs of users and the purposes specified in the survey . The perfect balance definition that was used in the past as well, because even if true Statistics can not be sure of the quality utility. In other words, a multi-dimensional quality statistics that are associated with all of its. Only one aspect of it is properly and it is perhaps the most important aspect. All aspects of quality are important However, in most surveys according to limited funds ,obtain statistics with the best level of quality in all its dimensions, it is almost impossible. This research based on SODA approach is monitoring data items quality from different directions and perspectives in order to problem structuring. Monitoring is base on documentation and scientific articles and semi-structured and depth interviews with experts in the field of statistics Data quality items Statistics Center of Iran. The researcher is trying to gather all the opinions of the experts, to structuring the relationship between the quality of its components and factors that affecting its. After setting out map to monitoring the data items quality, Level of quality items, its components, as well as factors that affect the relationship between the components are thoroughly characterized.

Conflict modeling and analysis have been investigated within many disciplines. Metagame based methods are the most comprehensive models that have been used for conflict modeling and analysis. The literature review outlines that common interest in the gas field shared between Iran and Qatar and lack of power balance between the two parties have caused conflict. Moreover, no serious study has been done on the aspects involved in the conflict. In this research we acknowledge the lack of a comprehensive study on the gas field shared. We employed confrontation analysis and drama theory to shed light on the potential issues involved in this case. Based on the data collected from several in-depth interviews, we present a framework depicting influential factors on the case of shared field between Iran and Qatar. While research findings show that negotiation under the current circumstances is impossible, a positive situation for Iranian side in the future is predicted. The research also suggests an appropriate strategy not only to resolve the conflict in Iran-Qatar partnership, also facilitate the creation of fruitful collaboration between the two parties.

Selection based on the traits affecting grain yield is used for its indirect improvement. The objective of the present study was to determine the quantity and mechanism of effects of agro-morphological and physiological traits on grain yield of bread wheat under terminal drought conditions. Thirty six advanced lines of wheat were evaluated in a Randomized Complete Block Design with three replications during three sequential growing seasons 2010-2013 under rainfed conditions. Stepwise regression, path analysis, and canonical correlation analysis were conducted. All three components of yield had a significant positive effect on grain yield. The first canonical variable of predictive traits (U₁) and yield components (V₁) were studied. In general, selection for shorter vegetative stage and longer grain filling period is recommended to improve wheat grain yield per plant under rainfed conditions. Also, the desirable lines were those that had high amounts of biomass, average plant height and spike length, and low amount of canopy temperature. These types of lines are expected to produce higher numbers of grain per plant (not per spike) and 1000-grain weight, simultaneously, and thus higher grain yield per plant.

Aims: Premature ovarian failure is a syndrome causing amenorrhea, infertility, and increases gonadotropin levels before age 40. The use of chemotherapy drugs can be one of the reasons that lead to this disorder. The purpose of this study was to evaluate the presence of germ cells markers in mice model of premature ovarian failure following chemotherapy drugs.
Materials and Methods: In this study, 24 mature female mice were used to create a premature ovarian failure model, different amount of cyclophosphamide and busulfan were applied (experimental groups 1 to 5). Bodyweight change, vaginal smear, morphological alternation of ovarian tissue in both experimental and control (without treatment) groups were evaluated and for the best model, hormonal evaluation (FSH, E2), and expression of germline markers (Oct4, Dazl) were examined.
Findings: Since, in the second group estrus cycle disorder, the significant decrease in weight and ovarian reserve (p˂0.05) were observed, compared to the control group, so this group was chosen as the best model. An increase in FSH level and reduction in estradiol level in the second group, compared with the control group (p˂0.05), confirmed creation of the POF model. Also, genes expression of Oct-4 and Dazl showed an increase (p˂0.05) in the second group compared with the control one.
Conclusion: The presence of germ cells markers in a mouse model of premature ovarian failure following the use of chemotherapy drugs can be a new hope in the treatment of infertility in cancer patients after chemotherapy.

Iran is a multicultural country that encompasses various ethnic, lingual and religious groups. The purpose of this article is to show how does the constitution of the Islamic Republic of Iran deal with the issue of cultural diversity? We used the method of conforming theory with sample. Cultural citizenship theories are also used as a theoretical framework to analyze the solution. The most important finding of this study is that the Constitution of Iran provides a two-layer solution for the issue of socio-cultural diversity. The lower layer comprises cultural politics of centralism which, in turn, is the result of domination of Islamic, Shiite, Persian, and patriarchal culture. In contrast, the upper layer comprises a combination of politics of wide recognition (especially in language and ethnicity areas) and politics of narrow recognition (especially religion, women, and vulnerable social groups). Although the constitutional solution has similarity with modern culture citizenship, some citizens (including ethnic, religious and sexual minorities) do not consider the complete autonomy.

Conjunctions making up a group of 10 types are of importance in Arabic. One of them -or- which is equivalent to "or" in Persians relates follower and followed in terms of meaning and role.  It is said to have many implications in different contexts including Qur’an. This research is focused on the properties of this conjunction in both languages and the most important semantic features of them, and their grammatical structures. Also, it investigates the relationship between context and diexis in determining the meaning of the two conjunctions.
The paper is based on an inductive-analytical methodology. It is a comparative study between “or” in Arabic and Persian. The study is aimed at describing grammatical, rhetorical, and semantic differences and similarities between them. For that matter, we selected poetic and prose passages of the holy Qur’an and those of Saadi, Molavi and Hafez.
Research results are: “Or” in Arabic is used between the follower and followed while in Persian it is used before follower and between follower and followed. “Or” in Arabic and in Persian has multiple semantic meanings. Some of these semantic meanings are shared between these two languages while they can differ in terms of semantic aspects such as detail and pure differentiation which are commonly used in Arabic but are absent in Persian.

Abstract:
Objective: Despite the availability of effective vaccines and antiviral treatments, influenza remains a significant cause of hospitalizations and mortality globally. This study aimed to evaluate the epidemiological characteristics, clinical manifestations, and outcomes of patients diagnosed with seasonal influenza in two referral centers in northeastern Iran.
Methods: This retrospective cross-sectional study analyzed data from 58 patients with a mean age of 45 who tested positive for seasonal influenza via PCR. These patients were hospitalized at Imam Reza and Qaem hospitals between 2009 and 2017. Data were collected using a standardized checklist and analyzed using SPSS software version 23. Non-normally distributed data were assessed using the Mann-Whitney test, while qualitative variables were compared using the Chi-square test, with Fisher's exact test applied when necessary.
Results: Among the 58 influenza-infected patients, 37 (67.2%) survived, 18 (32.7%) died, and 6 (10.9%) were discharged at their own request. Influenza A subtypes identified included H1N1 (15.7%) and H3N2 (23.6%), with 60.5% remaining untyped. Antiviral drug administration did not significantly correlate with hospital mortality. However, initiating antiviral treatment within the first 48 hours did influence mortality outcomes. Patient age, influenza virus type, and subtype showed no significant relationship with hospital mortality.
Conclusion: The study highlights concerning clinical outcomes and hospital mortality rates among patients diagnosed with seasonal influenza. Given the preventable nature of influenza and the challenges in managing these patients, there is an urgent need to enhance physician awareness, particularly among specialists. Emphasizing timely diagnostic and therapeutic interventions is critical, especially during peak influenza seasons.

Rationality or relativity? In which one does Farabi believe? How does it relate to imagination and the permanent, if at all? For Farabi, people come to grasp rational truths mostly through the use of their imagination. Furthermore, the arousal of people’s feelings and emotions often originates in their imagination via imagery forms. The ultimate utopian goal is to drive the public to achieve rational happiness. Since the public, based on their nature and general habits, in effect cannot perceive the rational truths, the path to rational happiness must be represented via their imagination. Moreover, their imaginary concepts and forms should be made the permanent. So bringing rational happiness to people's minds through their imagination, the media of each society should represent rational truths through the sensory and imagery forms familiar to that society. The Farabian theory of cognition shares aspects of relativity as well as rationality. To Farabi, rational truth and rational happiness is fixed and one, having only one denotation, while its connotations, say, images and imagery forms are various and sundry. That being the case, different communities can have different ways to perceive the same truth, working toward the same goal.
