Aims: Movement is a means for percipience the urban space and the concept of the city is expressed through movement within it. But today, the image of the city that can be seen while moving (whether on foot or on horseback), it does not induce a concept other than relocation and transfer.

Methods: the research method is descriptive-analytical (content analysis), in order to objectively and qualitatively describe the content of the concept of movement and rest, using texts and documents (written, oral and visual) in a systematic and purposeful way.

Findings: Positive and purposeful movement in cities and meaningful moment (a movement that during going somewhere, be positive impact on the sensibilities of the citizens), and the rest that calms the audience in urban spaces, it has not been seen in modern city. the point of this research is recognition of principle of movement and rest, and its application in organization urban movement systems.

Conclusion: the case study, is the Quran Gate of Shiraz, which is a successful example in applying the principle of movement and rest in all its dimensions. according to research conducted in order to organize urban movement systems it is necessary to pay special attention to the spiritual dimension of movement (meaning to movement and rest) and change the single-movement system (in the past) to simultaneous movement systems (in today's cities).

The building sector is responsible for one-third of global final energy consumption and thus environmental damage, carbon dioxide production. Some reasons for ever increasing building energy consumption : climate change, increase in household electricity load , the growth of real estate, fast-growing household electrical appliances, changes in industrial structure, huge energy consumption of the existing buildings, and the lack of strict government supervision. The world's total energy requirements are mostly used in sectors such as transportation, industry, residence, commerce, etc.. Although most of the energy consumption during the period 1973 to 2009 belonged to the industrial sector, it can be said that the proportion of residential buildings is very high and is increasing rapidly.. World Statistics published by the Department of Energy, United States of America in March 2010 shows that most houses widely use energy for heating and hot water and then cooling and lighting. Therefore, the revision of quality architectural design of buildings, based on the climatic principles , will be very effective in optimizing fuel consumption so that the energy consumption can be controlled wisely and optimally. On the other hand the use of renewable energy technologies can provide energy surplus of buildings and eliminate the problems associated with fossil energy in great extent.Adopting conservation measures on a large scale does allow reducing both electricity and total energy demand from present day levels while the building stock keeps growing. They simulate climate-dependent hourly building energy demands at user-defined scales, typically an individual state or utility zone. Due to the effective role of energy in economic development and its increasing consumption in parallel with the growth of human communities , considering resource constraints and preventing from facing with an energy crisis, the need for conservation through management application is necessary which demands new strategies and approaches in both environmental and architectural revisions for design and building. In particular, the high energy consumption especially in buildings is a major problem in developing countries which has economic and environmental impacts of prime importance while it is considered to be the most significant cornerstone of growth in different dimensions. Buildings , it is statistically shown, account for a third of total global energy consumption. Energy consumption in buildings is increasing due to several factors including climate change, increasing electrical energy consumption in households, real estate development, diversity of modern appliances, changes in industry structure, very high energy consumption in existing buildings and the lack of adequate supervision of the state.. Therefore, efforts must be focused on the control and management of energy consumption . The purpose of energy management is reducing energy consumption in a way that is logical and economical and can cause no negative effects on welfare and thermal comfort. So, a focus for building energy consumption efforts is of great importance. The occupant behavior and building manner can both increase the building energy consumption, especially residential ones.In the building quality part, there are many techniques affects on building energy consumption, which divide to passive and active. The passive ones are the techniques that related to the body and design of a building as material, utilization of solar radiation on the bodies, length and width of building, insulation, window, and so on without electrical or other energy portfolio, but the effect of these parameters was not equal. Therefore, this study presents an approach to determine the effect of main parameters of some of the building techniques on energy consumption. In this study, these parameters were identified and evaluated and finally were Prioritized. Not all of the parameters has equal role on energy consumption, which the mentioned weights indicated. The remainder of the paper organized as follows. Firstly, the parameters were identified by research and interview. The effective parameters recognized as the alternatives of the mentioned hierarchy3 step trees, which can be listed as follows: occupants; built area; Step No.; Proximity degree; Window to wall ratio; Length to width ratio; Side. Secondary, the questionnaire performed and completed by experts as architects, mechanical engineers and energy engineers. Analytic hierarchy process (AHP) and its applications in surveys related to buildings were presented. Up to now, the AHP method has been widely applied in the general policymaking in buildings. Next, the effective parameters on energy consumption evaluated, and in next section the AHP for the approach concernedexplained and resultsoffered. Finally, the last Section includes the concluding remarks. The weights and priorities of the effective parameter are illustrated. As a result, considering weight of factors in building designing process, the different parameters of BO can be classified and evaluated: First, the main effective parameter is window to wall ratio. Depends on the weight of this parameter (0.36), the window area and materials are important for building designers. Another main parameter is side no., if a building has 1 or 2 or 3 or 4 side, its energy consumption differs fundamentally. Choosing the main direction, side and the side no. are all associated. One of the main results is about the building area depending on energy consumption, which considers having the main role, but in present survey concluded that the third effective parameter is area. The least effective parameter is occupant number, due to energy load of building space and quality, not building occupant. Urban designers and Architects considering Building Orientation (BO) and its parameters can design buildings that are energy efficient. If building orientation )BO( is considered, solar radiation absorbed by the surface structure of the building will become more favorable, and consequently the energy consumption will be reduced. However, if the building orientation (BO) is considered along with climatic factors, there will be direct effect of increased energy costs. In addition , urban designers must greatly pay attention to building sides while determining the building blocks as the transmitting surfaces are from outdoor to indoor in summer and vice versa in winter. Architects must also pay attention to different ratios of windows to create the proper ratio of heat transfer in the buildings. The materials used in the buildings are of great importance.

For quality assessment of coated fish fillet with sodium alginate containing inulin, fish fillet were coated with sodium alginate containing 10, 20, 30 and 40 percent inulin using two methods, including dipping and vacuum impregnation. Then fructan were determinate in coated samples. The samples including 20 and 40% inulin in vacuum impregnation and dipping respectively were selected for further study based on their higher fructan content. Therefore, the chemical and microbial changes of selected samples were investigated during 16 days, with 4 days interval in refrigerated condition (4⁰C). Results showed that the fructan content had not changed significantly (p≥0/05) during the storage period. Peroxide in the middle of storage period was increased and then decreased significantly (p≥0/05) by the end of storage time. Quality indexes such as pH, thiobarbitoric acid (TBA), total volatile basic nitrogen (TVB-N), total plate count bacteria, psychotropic bacteria and peroxide increased significantly (p≥0/05) along time. In all of the samples, TBA at the end of 12 day storage, TVB-N at the end of 16 day storage, anaerobic bacteria count and pseudomonas bacteria count at the end of 12 day storage were more than acceptable limit of fresh fish. In the conclusion, fructan of coated fish fillet had not changed significantly during refrigerated storage, as well as shelf life of coated fish fillet by dipping and vacuum impregnation in refrigerated condition storage (4⁰C) was less than 12 days.

The phenolic compounds of pomegranate (Punica granatum L.) peel extracted by two methods (solvent and ultrasound-assisted) with five solvents (acetone, methanol, ethanol, water and ethyl acetate) were compared with supercritical fluid extraction (SFE). The total phenolic compounds were determined according to the Folin-Ciocalteu reagent using tannic acid as standard. The overall results showed that acetone with sonication produced the maximum amount of phenolic compounds from pomegranate peel extracts (PPE). Furthermore, the effect of the acetone extract of pomegranate peel (0.010-0.050 %) on the stability of soybean oil during heating at 60oC (oven test method) was determined by measuring peroxide and thiobarbitoric acid values. At a 0.050 % level of pomegranate peel extract, its antioxidant activity was greater than 0.02 % of the two synthetic antioxidants butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT). The pomegranate peel extract possessed a relatively high antioxidant activity and might be considered as a rich source of natural antioxidant.

Tea and sesame seed oils extracted by different methods (including supercritical fluid extraction (SFE), at a pressure of 350 atm, a temperature of 60oC, a static extraction time of 20 minutes, a dynamic extraction time of 30 minutes and 150 g kg-1 of ethanol as a modifier). Solvent (SE) and ultrasound-assisted solvent extraction (UE)), as natural anti-oxidants, were evaluated during 15 days storage by monitoring their effects on refined sunflower oil at 60oC. The peroxide value (PV) and the thiobarbituric acid (TBA) value were used to assess the antioxidant activity of these extracted oils. The highest extraction yields were from SE and SFE, while UE gave a lower yield. Considering oil extraction yield and antioxidant activity, SE and SFE were the preferred methods. The results showed that tea seed oil had strong antioxidant activity, which was almost equal to sesame oil. Therefore, tea seed oil can be used in the same way as sesame seed oil in fat, oil and other food products as a natural antioxidant to suppress lipid oxidation.

Objective: The LRR (leucine rich proteoglycans) is a molecular recognition motif found in proteins with some roles in cell adhesion, signal transduction, DNA repair and RNA processing. Opticin is a member of this family. Takanosu et al (2001) detected messenger RNA expression of mouse opticin in the eye, heart, brain, testis, thyroid and epididymis by dot blot hybridization. In this study, expression levels of mRNA and protein of opticin was investigated by two monoclonal antibodies which were raised against opticin peptides. By this method structure of opticin in human and mouse has been studied. Materials and Methods: Mouse tissues including, kidney, testis, liver, lung, heart, brain, muscle, spleen and eye were isolated. Opticin expression was identified at mRNA and protein levels by RT-PCR and Western blot. Results: PCR analysis revealed that opticin mRNA is expressed in all the tissues studied except for the lung. However, opticin protein was detected in all tissues analyzed. Conclusion: Expression of opticin in the adult murine tissues may suggest functions other than that of putative regulation of vitreous collagen fibrillogenesis for this molecule.

Phenolic compounds, especially those of plant origin, constitute an essential part of the human diet, and are of considerable interest due to their antioxidant properties. In this study, Ultrasound-Assisted Extraction (UAE), Microwave-Assisted Extraction (MAE), as well as Maceration Extraction (ME) methods were applied for phenolic compounds’ extraction from pistachio green hull. Response surface methodology was employed to optimize the extraction conditions as regards the yield of the compounds. A Central Composite Design (CCD) was employed to investigate the effects of three independent variables, namely liquid-to-solid ratio (8-20 times), temperature (25-65 °C) and time (5-45 minutes) on the dependent variable (level of total phenolic compounds). The results indicated that within the same extraction time, the extraction yield through UAE was higher than those in ME and MAE methods. Correlation coefficients (R2) of the models for UAE, MAE and ME methods were 0.95, 0.96 and 0.94, respectively. The optimal conditions for extraction of phenolic compounds from pistachio green hull through ME, UAE, and MAE methods were 20(v/w), 65°C, 45 minutes; 20(v/w), 65°C, 25 minutes; and 20(v/w), 65°C, 45 minutes, respectively. Under optimized conditions the experimental values well agreed with the values predicted by the proposed models.

Standard political discourse is replete with ambiguity and vagueness. Politicians frequently use vague language to hide their inadequate knowledge, show their low interest in the issue, and/or evoke emotion. This study reports on a qualitative content analysis of vagueness in two Iranian presidents' political interviews within a pragmalinguistic and sociopolitical paradigm. The data consisted of nine question-answer exchanges extracted from seven internationally live broadcast interviews. A total of 57 instances of vague language use were analyzed in terms of 21 pragmalinguistic vagueness strategies. Implications are that vagueness in political discourse is motivated by a multiplicity of factors such as face management, sociopolitical and situational adaptation, conflict avoidance, and personal characteristics of the interviewers and the respondents. Vagueness was also found to be a sign of diplomatic prudence or wisdom.

Due to disadvantages of synthetic packaging materials such as migration into food, polluting of environment, difficulty of recovery, high costs of raw materials and production, also for development of properties of starch based edible film, in this study nanocomposite films from starch and montmorillonite (MMT)  fabricated and their properties investigated. In this regard, nanocomposite films formulated by mixing starch and four levels of nanoclay (0, 1, 3 and 5%) and three different concentrations of glycerol (20, 30 and 40%), then the physical and mechanical properties of film measured and appropriate film selected.  5 % nano-clay could  improve tension resistance (38%) and moisture permeability (33%). The results from XRD showed that nanoclays spread evenly in starch polymer. The effects of ultrasound waves on the optimum film were investigated. These waves improve mechanical properties and permeability of films remarkably. 30 minutes was the best time of ultrasounication processing. Results showed that optimum nanocomposite of starch-nanoclay could be used as a biodegradable suitable packaging for preserving food.

There has been a renewed interest in edible films made of renewable and natural polymers such as protein, polysaccharide and lipids. Natural polymers derived from natural sources like food protein, offer the greatest opportunities because of their biodegradability and their ability to supplement nutritional value of foods. Faba bean is a valuable source of protein and is cultivated in large quantities in Iran. Therefore, in this study, we investigated the potential of faba bean protein isolate (FPI) as a new protein source for preparation of an edible film and determined the effects of film forming solution pH and plasticizer concentration on the film properties. Results showed that increasing the pH improved mechanical properties (tensile strength and elongation) and solubility of the films, but, caused the water vapor permeability (WVP) and lightness of the films to decrease. Plasticizer concentration did not affect WVP over the studied range. Elongation and solubility of the films increased and the tensile strength decreased by increasing plasticizer content of the film forming solutions. The lowest WVP and the highest tensile strength were observed at pH 12 and 40% (w/w of FPI) glycerol concentration.

Oxalate Soluble Pectin (OSP) is related to fruit firmness with respect to the chelation of calcium ions with carboxyl groups of adjacent polyuronide chains. This study was carried out to explore the effect of time of fruit harvest, foliar spray with CaCl2 during growing season on OSP, Polygalacturonase Activity (PGA), fruit firmness and the effects on fruit shelf life, quality and Internal Browning (IB) disorder. Fruit samples were collected from Asian pear (Pyrus serotina Rehd.) trees ‘KS’9 and ‘KS’13 on European pear (Pyrus communis L.) seedling rootstocks. Fruits were picked on the 1st and 15th August, 2006 and stored at 1ºC and 80-85% relative humidity (RH). Five stages of extraction were performed on fruit samples including one pre-harvest, one at the time of harvest, and three following fruit harvest. Results indicated that OSP increased slightly during fruit ripening as well as during storage. In both the studied cultivars, the level of OSP in fruit harvested fifteen days after Optimum Time for Harvest (OTH) was higher than that harvested at OTH. The level of OSP in fruit softened after harvest significantly increased starting from the time of harvest. The relationship between flesh firmness, IB and OSP concentration showed the highest correlations in the both of the studied cultivars among PGA. In conclusion, flesh firmness and IB were correlated with the extent of OSP concentration. In addition, fruit, sprayed with CaCl2 and harvested early, contained less OSP, PGA and IB following long-term storage.

Tobacco (Nicotiana tabacum L.) is an important industrial crop and its seeds contain significant amounts of oil. The extraction of oil components using solvent at high pressure, or supercritical fluid (SCF), has received much attention. In the present study, statistical analyses showed that the average extraction yield of seed oil of five tobacco varieties using SFE was 9.33%, which was higher than Sonication (7.75%) and DGF (Deutsche Gesellschaft f_r Fettwissenschaft) standard method B-I5(87) (8.48%), but lower than Soxhlet (13.72%). Also, fatty acids profile of each extracted oil was determined by gas chromatography. Various saturated and unsaturated fatty acids such as lauric (C12:0), myristic (C14:0), palmitic (C16:0), palmitoleic (C16:1), stearic (C18:0), oleic (C18:1), linoleic (C18:2), linolenic (C18:3) and eicosanoic (C20:0) acids were observed in the extracted oils.
