Abstract:
Persian Gulf region during the last decades of the new century, the most important region of the world and will continue to play an important role in international politics. There are many reasons for the importance of the Persian Gulf. First, the global oil and gas reserves in the Persian Gulf littoral states and lies and concentrates. In the new century provide.
In other words, the horizon of the world needs oil rich Persian Gulf region, there is another Enough energy to power industrial countries, especially the developing or developed in the U.S., Europe, Japan, China, Korea, and the Indian subcontinent to meet the new century. It is important to measure the effect of events such as wars, revolutions and rebellions, the area of oil and gas will continue to fail. Pressure on the consumer countries in the energy level of the international will to Persian Gulf the scene in such a compilation and in the framework of the carrier to the production energy sides and disorder entered serious basic interests to not damage their little not to enter
Iran is located at the center of strategic energy ellipse Middle East geopolitical areas and especially those versed in the political geography of the north side of the Persian Gulf and Oman Sea Oceanic Influence on India\'s fundamental role in the geopolitical strategies of international interaction Iran has brought. No doubt balance in the Persian Gulf is so broad in scope impacts the area in any structure a new geopolitical levels international vibrations may cause.

Abstract. Focusing on high-quality construction, and improving seismic performance of under-construction
buildings on one hand, and rapid elimination of housing shortages and/or other spaces and buildings required in
the country on the other hand, clarify application of the modern technologies instead of inefficient and
traditional systems. Hence, the main aim of this study is to reorganize, prioritize, and determine the status of full
construction systems using industrial production methods.
In this study, each of the technologies has been evaluated from two main structural and architectural
perspectives. In order to obtain the predefined objective, the main element of the research has been studied
within the three criteria of quality, economy and speed. It is hoped that every technology will find its special
position in the building industry in terms of capability of construction and operation.
With due observance to the above mentioned subjects, and in accordance with the results of the present study,
common construction methods in the country have not met demands of mass housing construction. Among
industrial construction systems, although Light Steel Frame (LSF) has obtained higher status than others have,
however, it needs to be modified in order to improve its performance and obtaining better ranking among other
technologies.

This study aimed to determine the relationship between personality characteristics and parenting styles with video computer games dependency among secondary students (males and females) in Ahvaz city. There were 872 participants from different educational regions of the city (four regions) which were selected via a multistage cluster method of sampling. The applied instruments included temperament-Character inventory (TCI-125), parenting styles Questionnaire (PSQ) and problematic video game playing test (PVGT). The achieved data was analysed by applying Pearson correlation as well as multivariate regression. Findings indicated significant relationships between personality characteristics and parenting styles with video-computer plays dependency. The best predictors of the plays dependency were self-directiveness, gender, novelty seeking and freedom-control dimensions, respectively. These results showed that high levels of self directiveness, novelty seeking and freedom-control lead to the plays dependency.

Fractal image compression (FIC) is recognized as an NP-Hard problem, and it suffers from a high amount of MSE computation. In this paper, a two-phase algorithm was proposed to reduce the MSE computation of FIC. In the first phase, based on edge property, all range and domain blocks are classified. In the second one, imperialist competitive algorithm (ICA) is used according to the classified blocks. For maintaining the quality of the retrieved image and accelerating algorithm operation, we divided the solutions into two groups: developed countries and undeveloped countries. Simulations were carried out to evaluate the performance of the proposed algorithm. The obtained results showed that the proposed algorithm performs better compared to GAs, and Full-search algorithm in terms of decreasing the amount of MSE computation. Although the proposed algorithm decreases the amount of MSE computation for 463 times faster than the Full-search algorithm, the quality of the retrieved image (e.g., Lena picture) did not change considerably.

Biodiesel is a renewable fuel that can be produced from vegetable oils, animal fats, or waste oils for use in diesel vehicles. Biodiesel\'s physical properties are similar to those of petrodiesel, but it is a cleaner-burning alternative. In this work, waste cooking oil and methanol as feedstock together with sulfuric acid and potassium hydroxide as catalysts were used to produce biodiesel. Physical properties of waste cooking oil, produced biodiesel and purchased petrodiesel were measured using specified ASTM standards. To examine their performances and emissions of their flue gases, biodiesel and petrodiesel were burnt in a wet base semi-industrial boiler. The emitted gases of combustion were measured with a flue-gas analyzer at a wide range of air to fuel ratios and two levels of energies. For better reliability, all tests were repeated five times and almost no sensible differences were found in repeat tests. The results show that biodiesel meet ASTM standards. These properties of biodiesel are also comparable with the petrodiesel properties. The trends of exhaust temperature and combustion efficiency of biodiesel are the same as petrodiesel at different air to fuel ratio. However they are slightly lower. The CO, NOx, SO2 and CO2 emissions of biodiesel are lower than those of petrodiesel at different air to fuel ratio and two levels of energies

In this research, a rapid, solvent-free and single step method for the analysis of essential oil compounds in dry rosemary leaves (Rosmarinus officinalis L., Lamiaceae) using gas chromatography–mass spectrometry (GC–MS) following microwave distillation and headspace solid-phase micro extraction (MD-HS-SPME) is reported. Compared with a conventional technique, HD., the advantages of the proposed method are: a short extraction time, good precision, and high extraction efficiency. All experimental results show that the presented method is an alternative tool for the fast analysis of essential oils in dry rosemary leaves.

Background: Sensation seeking is used to describe general features including high risk behaviors and inability to tolerate boredom. This study was conducted to investigate the relations between sensation seeking and stress among students of Bandar Abbas. Methods: In this cross sectional study, 400 students who had all the enrollment criteria were chosen by cluster sampling. A questionnaire was used to collect data. Results: The study showed that the mean excitement score was 16.66 ± 3.39 and with a maximum score of 27 and a minimum score of 8. Also, the mean score of experiment seeking was 7.70 ± 1.86 with a maximum score of 13 and a minimum score of 3. The mean score of tolerance towards boredom was 2.22 ± 1.3 with a maximum score of 9 and a minimum of 0. The mean score of escape inhibition was 1.34 ± 0.226 (max:2, min:0). Among all the participants, 35.3% had a moderate sensation seeking and above, and 71% had moderate stress. Conclusion: According to the results of the study, sensation seeking had no significant associations with stress.
