Abstract
Nowadays the issue is that most Islamic traditions have been neglected in the society. The influence of theological and religious values on the construction and development of urban spaces are much more important. In the present study an attempt was made in order to define the Islamic city and its requirements and investigate the role of spaces related to rituals and religious ceremonies held in commemoration of Muharram through a case study of Timcheh Mozaffarieh in Tabriz Baazar. In investigating the theoretical way of study is a descriptive-analytical method and for the sample survey-analysis was applied. Data collection was done through interviewing the experts and scholars in religion, library study of the theories and definitions on the subject and field study (questionnaire). In the studied case (Timcheh Mozaffarieh in Tabriz Baazar) it was also observed that many people from most of the groups (people participating in ceremonies, businessmen in downstairs of Timcheh, businessmen in upstairs of Timcheh, heads of mourning groups, Islamic Development Staff and police) agree upon holding the five-day mourning ceremony in Timcheh Mozaffarieh in Tabriz Baazar despite of some problems, since it has been held there for about a century and transferring it to another place will damage its glory. The reason we have observed in the obtained results and findings is the sense of belonging and attachment to this place after years of holding many ceremonies in this place and the memories people have of it in their minds which are part of their lives. Another reason is the identity that holding Muharram ceremonies have given to this place through all these years. Therefore, identity along with memorable and repeatable events reinforces the potential of this place. According to the obtained results, most of people in 5 groups (people participating in ceremonies, businessmen in downstairs of Timcheh, businessmen in upstairs of Timcheh, heads of mourning groups, Islamic Development Staff and police) have agreed upon holding Ashura and Tasua mourning ceremonies in Timcheh Mozaffarieh in Tabriz Bazar which gives a special identity and fame to this place, and provides a sense of belonging to it. However, there are some problems in holding these ceremonies and an attempt was made to solve them by studying the problems and suggesting some solutions and also try to maintain the originality and durability of this precious place, which is due to holding special rituals and mourning ceremonies in Muharram, by inviting participants in these ceremonies, heads of mourning groups and businessmen in Timcheh to help.

Abstract
The decoration of potteries was very important in prehistoric and before protoliterate periods. The structure and motives on the ceramics accommodate the possibility of the study about ancient human thoughts and demonstrate the dependence of his ideas and minds on the natural and social environments in which he has lived and grew up. Therefore, by examining these motives, one can study and analyze the mental, ideological, social and economic complexities of ancient societies. The authors have studied the organization of pottery production in an ancient society by researching the "grammar" of motives and aesthetic quality of prehistoric painted pottery. The culture of Tall-e-Bakun A which has prevailed in Marvdasht plain in Fars Province at the end of 5th and the beginning of 4th millennium BCE, is the case study of this investigation.
The ceramics have been produced in a standardized productive organization and a specialized process during Bakun A phase. Requirements and rules have been used in creating patterns on pottery of this period, the most important of which are: placing motifs in frames, symmetry, repetition, reversing and clockwise direction of motifs, creating motifs with negative technique and using separating elements. This study also has proved that the relationship between the designs and the forms of the potteries has been relative. The grammar and method of motives on jars, cups and bowls have shown that often the same patterns and models are used in their execution. The execution of them.

Abstract
Objective: Bacillus cereus (B. cereus) is a gram-positive, spore-forming bacteria widely distributed in the environment. This bacteria is an opportunistic human pathogen that can cause diarrheal and emetic types of food poisoning. The diarrhea type of food poisoning can be caused by hemolysin BL (HBL), non-hemolytic (NHE), and cytotoxin K enterotoxins. Rice is commonly contaminated with B. cereus. The objective of this study is to detect enterotoxigenic genes of the NHE complex and assess their incidence in B. cereus isolates in rice samples from Zanjan, Iran.
Methods: We randomly purchased 10 different rice samples from food stores and cultured them in PEMPA. Following biochemical testing, the bacterial colonies were identified by PCR. B. cereus isolates were checked for the NHE complex genes by specific primers using multiplex PCR.
Results: Results showed that rice samples were contaminated with B. cereus. The NHE complex genes were found in 8 bacterial samples.
Conclusion: B. cereus is able to tolerate high temperatures; in cooked rice the spores can undergo germination by reheating. The results of this study have shown that NHE multiplex PCR is a prompt, reliable method for the differentiation between non-enterotoxigenic and enterotoxigenic isolates of B. cereus. Despite its common dietary role, rice in Iran has rarely been investigated from a microbiological point of view. Enhancing awareness about virulence and prevalence of genes involved in food poisoning would be effective in the prevention of food poisoning.

Abstract
The pectinase enzyme has a great importance in the food industry. It is capable of decomposing Pectin significantly, which is the substantial element of turbidity of the juices. As a result, it plays an important role in clarification also ability to maintain organoleptic properties and quality of nutrients. The usage of enzymes in the industry is costly and some measures should be taken to allow the enzyme to be used several times without altering its efficiency. In this research the commercial pectinase enzyme was immobilized on calcium alginate beads. Free and immobilized enzymes activities in different temperatures and pH were determined. Then storage stability and reusability of enzyme were investigated. For optimized clarification of tomato juice by immobilized enzyme, the response surface methodology was used. Three factors including temperature (30-45°C), time (15-45 min) and enzyme concentration (2-6%) in 3 levels were used to evaluate the effect of parameters on turbidity of tomato juice as a model system, the importance of interacting the effects of factors also determined. Optimization has been conducted to achieve the lowest turbidity of tomato juice at the lowest used enzyme. Optimized conditions achieved by concentration of immobilized enzyme 2%, temperature 45◦C and time 45min, and with yield of clarification 27/09 times for tomato juice. Results showed that the best temperature and pH for free and immobilized enzymes were 45°C and 3, respectively.

Abstract
Roll motion is one of the most important and dangerous motions of the ship and can even result in capsizing of the vessel. Therefore, its control has been always of interest for marine industry researchers. Among the various methods and equipment for controlling the roll motion, the use of free surface anti-roll tanks has been one of the most important methods and which used in many cases due to its simplicity in construction and design. The high efficiency of these tanks at all speeds and even without speed is another strength of these tanks. This study investigates the effect of the free surface anti-roll tank on the roll motion numerically and experimentally. In the numerical simulation, a CFD sloshing solver, based on the “Open source Field Operation And Manipulation”, known in short as Open-FOAM, and assuming 2D laminar flow conditions, is customized to calculate the sloshing loads from the tank. The predicted roll damping and moments due to the anti-roll tank are validated against experimental results. This simulator could be used as a sloshing simulator to couple with seakeeping solvers.

Abstract
Sandwich panels which can be used as an explosion shield are important structures for absorbing explosion energy. Crushing and plastic deformation of the core with the plastic bending of the faces are the main factors in absorbing the explosion energy in this sandwich panel. Structural components undergo permanent deformation after explosion and energy absorption. In this paper, the energy absorption of the structure and the deformation of circular metal sandwich panels with tubular core under explosion load have been investigated analytically, numerically and experimentally. The tubes are arranged radially and symmetrically in the core constructions. The experiment have been performed by making sandwich panels under free blast load in order to evaluate and validate analytical and numerical results. The analytical solution is performed using the energy method by balancing the kinetic energy and the plastic work which is done by the different components of the sandwich panels. Numerical solution is performed in ABAQUS finite element software and the pressure function is generated by CONWEP method. The amount of energy absorbed by the structure and different parts of it is obtained. There is good agreement between the results in different ways.

Abstract
The archaeological site of Afalleh is located in the north of Khachak village, in the intermountain plain of Kojour, in southern end of Nowshahr District, Mazandaran Province. Drawing on the available evidence, the site is dated to the Parthian period. Afalleh is clearly an archaeo- metallurgical center in the area, and by virtue of its relatively large size (more than 5 ha) might be one of the most significant and/or important archaeo- metallurgical sites of the Parthian period in the entire region. Large and dense scatters of slag and kiln wasters, especially in southern and western quadrants, hint at extensive and/or long-termed archaeo- metallurgical activities at the site. The surface slag could be divided into two groups of sponge and dense with a dark color near to black. Most slags are seen on southern part of the site. A stone building is partially exposed in western side of the site, where a dirt road has cut a part of the archaeological deposits. Macroscopic and microscopic analyses indicate that the slags are rich of fayalite and wustite, ferrous silicate and iron oxide minerals, respectively. Inside one of these slags a thick prill of iron is observed that has been largely replaced with secondary iron oxides. This observation indicates an indirect reduction of iron from its ore-producing carbonized iron (steel and cast iron)-and refers to its separation from silicate melt more probably outside of furnace. In this paper we describe the site and data has produced concerning the probable extent of the smelting activities, this is a comparative study and is a discussion on possible provenance of ore deposits.

Abstract
The design and optimization of multiple production systems, including systems that simultaneously generate heat, power and freshwater, play an important role in improving the performance of these systems. In this study, after modeling a multi-effect evaporative desalination system MED and simultaneous heat and power generation CHP, they are combined to meet the demand for heating, power and fresh water for a hotel. The purpose of this study is the thermoeconomic evaluation of the use of thermal energy storage TES tank in the combined system CHP + MED compared to the non-use of this tank. The strategy is applied every 24 hours of the two seasons. In optimizing this system, the annual cost minimization has been done as a objective function and using genetic algorithm. Optimal technical results in these systems show that the system CHP + MED + TES requires a gas turbine with a nominal capacity of 12% larger and a backup boiler with a nominal capacity of 7.14% smaller than the system CHP + MED. The optimal results of the economic comparison show that by using the thermal energy storage tank in the combined system CHP + MED, the annual cost is improved by 4.91%.
