This research has been done with the topic of investigating the relationship between social marketing and brand value dimensions. Paying attention to the competition and understanding the market of the desired behavior is the key to success in using the social marketing point of view. A correct understanding of the competitor's ideas and behaviors and increasing the amount of benefits of the desired behavior or reducing the amount of costs and barriers to achieving it will change the competition market in favor of the product or service. is descriptive and survey. In this research, data was collected using a questionnaire. These questionnaires were distributed among customers by cluster sampling method and 254 returned questionnaires were initially approved. In this research, 6 hypotheses have been proposed. The final results of this research show a significant relationship between social marketing and brand value dimensions.

Non-cardiac chest pain (NCCP) is a common entity with negative effects on quality of life that places a large financial burden on health systems. This study aimed at investigating esophageal motility disorders in patients with NCCP.

This cross-sectional study was conducted in 101 patients with recurrent chest pain without any cardiac disease, attending Ahvaz Imam Khomeini Hospital in a one-year period. Those who had no evidence of gastroesophageal reflux disease (GERD) on upper endoscopy and 24-hr esophageal pH monitoring were referred for conventional esophageal manometry.

From 101 patients, 51 showed endoscopic or pH-metric evidences of GERD. Manometric evaluation was done in 50 patients, including 27 males and 23 females (mean age: 44.2 years, 26-68 years old). Half of the cases (n=25) had abnormal motility disorders, including nonspecific esophageal motility disorder (20%), nutcracker esophagus (10%), diffuse esophageal spasm (8%), hypertensive LES syndrome (8%), and ineffective esophageal motility (4%). Esophageal motility disorders were found to have no significant associations with weight and age (P=0.125 and P=0.285).  The rate of esophageal motility disorders were lower in non-smokers (P=0.019).

Esophageal motility disorders and GERD are frequent in patients with NCCP. Further studies are needed to establish a cause-effect relationship.

One of the main goals of researchers in the laser sintering process of metal powders is optimization of process parameters in order to reach the properties of manufactured parts to the raw material properties. In order to produce fully dense multi-layer parts, it is necessary to optimize the process parameters of a mono-layer part. In the present study, experiments have performed on a powder bed with the thickness of 5mm. The fabricated parts have been produced by a single laser scanning of the powder bed. By moving the laser beam on the powder bed, circular pieces with a diameter of 20 mm have been produced. Based on preliminary experiments and according to the input parameters, a function has defined for energy density. Therefore, output parameters have investigated based on weight percent of Cu and energy density. Results show that there is a saddle point in the diagram of the effect of energy density and the weight percent of Cu on output parameters. This point shows the transmission of sintering to complete melting. Optimal condition of manufacturing parts by rapid prototyping is the condition which strength, surface finish and dimensional accuracy are at the highest possible level while shrinkage, balling and thermal stresses are at the lowest possible level. The results show that the best condition is while the energy density sets between 120-140 W/m2 and the weight percent of Cu sets between 18-22 %.

This Paper, with the help of the device was made in this university as "rapid prototyping device base on direct metal laser melting", study interaction of metal powder apparent density and heat transfer experimentally. Selective Laser Melting (SLM) is a direct fabrication of part through layer by layer powder deposition and successive laser beam irradiation. One of the important properties of the SLM is thermal conductivity and thermal diffusivity of the metal powder. In this paper, thermal conductivity and diffusivity of metal powder with various apparent densities were studied. According to the method of measuring (the difference between two temperatures), The tests showed the dependence of thermal properties to metal powder apparent density. Changes in apparent density was established through the pressure applied to the raw powder bed. Because achieve to desirable apparent density through proper distribution is much expensive. This study was done in range of apparent density 44.75% to 56.4% compared to the density of pure iron. Comparing the samples produced in different densities it was understood that the pressure applied to the raw powder bed with the optimum point of arrest. In fact, the best quality of the manufactured parts, in density of about 46% was obtained.

In this paper it has been tried to identify and explain the clothing and garment types of Arsacid’s women based on historical reports and the representations of women in art, monuments and archaeological data of Arsacids. These data and the archaeological traces of the Arsacids such as sculptures, paintings of women on coins and wall paintings show that the Arsacid women as much as Achaemenid women have had significant presence in various social activities, but they always wore long, crease and loose robes, and even sometimes put a thin cloth like a veil on their head.

Adib Almamalek Farahani is one of the influential literary figures of the Constitutionalism Era in Iran. This era marks the beginning of great intellectual and political changes in Iran. Farahani is one of the figures who gradually changed his traditional ideas into modern ones. Concepts such as justice, the rule of law, which were rooted in the new circumstances of society, can be found in Farahani’s poetry that can be regarded as a literary revolution in Persian poetry; these concepts gradually dominated the mentality of the people and turned into slogans for the reformist movements. Farahani combines ethics and politics, and illustrates approaches for political unity. According to him, seeking freedom and complying with the rule of law are among the characteristics of enlightened people.
