  Considering walking not only as the earliest kind of urban transportation, but also it can lead to a high level of safety and comfort for people. Unfortunately, these days because of the lack of urban walking-based open spaces and low quality of these spaces, residents of present cities have encountered with serious problems for doing their social interactions. With a quick look at Ahvaz city (located at the western south of Iran) and most of Iran`s metropolises, obviously it can be found that most of Iran`s metropolises, in particular Ahvaz cannot meet their resident`s needs and expectations. Our purpose of this study is to assess the satisfaction of Salman Farsi street`s residents from the plan of sidewalk construction of this street in terms of its physical, social, economic and environmental dimensions. We use field and library methods to collect information in this kind of descriptive study. Our sample society is including the shopkeepers, residents and pedestrians of Salman Farsi Street and also we developed our sampling based on a random method. Considering this point that our sample size is 100 participants, we use SPSS Statistical Software and parametric, nonparametric tests such as Ttest, chi-square, correlation, Friedman for analyzing the questioners. Based on this study`s results, we can conclude that most of the street residents and users are satisfied with sidewalk construction of Salman Farsi street, in a way that the greatest satisfaction is related to its physical dimension, while most of the residents and users aren`t satisfied with its environmental dimensions.

  Knowing differences between different areas in the city basis of severity of the enjoyment of the different indicators, to determine the levels of development or deprivation, reduce regional disparities and programs tailored to the conditions and features of each region, necessity is inevitable. Therefore, the present study is a descriptive - analytical sought to achieve three aims: 1. determine the status of Ahvaz in terms of development in urban areas having different indices and the compilation model of Vikor, Topsis and Saw, 2. Offering a clear result and overall enjoyment of the situation according to results of the three models based on the techniques Kaplan, and 3. Comparing the model and also determine the a Proper Model to determine the enjoyment. The study population included 7 urban districts of Ahvaz. Data and information you need, including a 21 variable, by referring to municipal and metropolitan statistical yearbook Ahvaz is collected (about 94 years); To explain the situation to a better development of the regions of the facilities, required by GIS map is drawn. The results show that no area in the city of Ahvaz enjoys high status there, 25/57 % Regions of the two regions 4 and 1, is relatively high and the majority of the 5 regional areas, 2, 3, 8, 6, and 7 (71/43% of areas) in the state of being average and being developed. Topsis method also showed that equation changes dramatically better than other models (Vikor and Saw) for measure the status Regions have been Because the results of the model has changed drastically percent less.

  Integrated urban management means adopting a holistic approach and designing mechanisms to follow the above-mentioned approach in city affairs management. The purpose of this research is to investigate the integrated urban management strategies in Ahwaz. The method used in this research is descriptive-analytical. For this purpose, firstly, using library studies, interviewing and completing the research data collection questionnaire, using the SOWT model, a solution for integrated management in Ahwaz was developed. In this regard, the establishment of integrated management of the best decision to reduce and eliminate known deficiencies Became The t-test results show that the mean of all nine components is lower than the theoretical average (3), and their difference from numerical desirability is also negatively evaluated and estimated, meaning that most subjects have chosen a low and very low option. In the meantime, the status of the organizational structure component is more inferior to the other components of the situation, and the component of the system view and power are more favorable.

  The Asmari Formation (Oligocene-Miocene) is one of the most importance reservoir rocks in the Zagros Basin. This formation in the Mansouri Oilfield is composed of the mixture of silisiclastic - carbonate deposits which silisiclastic deposits are known as the Ahwaz Sandstone Member. Rock typing is a process in which geological facies determined with their dynamic behavior. Each flow unit is related to flow zone indicator, thus zoning of a reservoir using of flow zone indicators and identification of Flow units can be used to evaluate the reservoir quality based on relationship between porosity and permeability. To evaluate the reservoir quality and determining spatial distribution of petro-physical indexes in the Asmari Formation Sandstone, porosity-permeability relationship as well as their relationship with the rock types is used and finally Flow Units and Rock Types have been identified. In this study, the Asmari Formation Sandstone is divided into four flow units A, B, C and D. Within recognized flow units, flow unit C is the best one in the terms of reservoir quality and flow unit D also has a good reservoir quality. Comparison of determined flow units with porosity logs (neutron, density and sonic), it is observed that sandstone successions of Asmari reservoir affected by diagenetic processes like fracturing, dissolution, dolomitic cementation and hydrocarbon migration before cementation and flow units C and D are more extended, so porosity logs show good reservoir quality in this interval of Asmari succession. Thus it can be deduced that using hydraulic flow units, we can determine rock types groups in wells with core and then extrapolate the results into uncored wells. Manuscript profile

  Dust storms are dispersion of very fine solid particles in the air that lead to serious socio-environmental and economic problems. They have been widely observed in recent years in the sky of western and southern parts of Iran. The concentrations of dusts have sometimes reached up to a level estimated 66 times more than the acceptable and normal limits. In order to evaluate textural properties, mineralogical and chemical composition of dust samples were collected during dust storms that blew over Ahvaz metropolis in July and August 2014. The results indicated that statistical parameters of the samples were +6.10 phi, 2.17, +0.14 and 0.71 for mean grain size, standard deviation, skewness and kurtosis respectively. The main mineralogical constituents were quartz, feldspar, calcite and gypsum with a minor proportion of pyroxene, goethite, hornblende and biotite. The results also revealed that the shape of sand grains is well-rounded as a result of transportation and abrasion of these grains over a long distance. Moreover, XRD analyses of samples reflected the clay minerals fraction of dusts mainly comprised of kaolinite, polygorskite and chlorite. These types of clay minerals show a dry climate and an alkaline source area. Atomic absorption and X-ray fluorescence analysis showed major elements as Si, Al and Fe with minor elements such as Mg, Na and Ca. These dusts also contained minor and toxic elements such as heavy metals, and estimated enrichment factors showed that Ni, Co, Cd and Zn had high enrichment suggesting anthropogenic origin.

  Ahwaz Bangestan reservoir (Ilam and Sarvak formations with approximately 1000 meter thickness) were deposited in the Upper Cretaceous period, which is deposited in different sedimentological and tectonic situations. Ahwaz Bangestan reservoir is divided into four reservoir zones (C-E-G-I) which are separated by zones of dense limestone (A-B-D-F-H). This reservoir is formed due to repeating shallowing upward of shoal-bar to lagoonal facies with distribution of rudist debris, with the exception of younger sequence which belongs to deeper environment. Back shoal facies show frequent depositional changes in vertical and horizontal directions in zones C3-E-F-G-I, the changes which can be seen in reservoir. Furthermore, the effect of basement faults, with trend nearly N-S in Ahwaz Bangestan reservoir, resulted in changes of ancient paleogeography. These changes had an important effect on diagentic changes, depositional setting, and finally productivity in conventional and carbonate fractured reservoirs. Matrix porosity is fabric selective in zones C3-E-G-and I. So, grainstone, and packstone facies have better reservoir quality than wackestone and mudstone facies. Diagensis and meteoric waters affected the top of every exposure cycles, and caused the best reservoir quality in grainstone, and packstone facies and productivity of wells. But, zone C1 of Ahwaz Bangestan reservoir (chalky limestone) experienced dominantly solution and leaching, which caused an increase in matrix porosity, but little changes in permeability. Furthermore, the open fractures developed in zones E, F and G which are located in the central and southern parts of the field. Existence of open fractures are confirmed by mud losses, analysis of sedimentary structure and dynamic reservoir data. Increase of mud losses in some area of limestone zones (D, F, and H) could be an indication of vertical relationship of two reservoirs and absence of sedimentological barrier in these areas.

  Holding rituals in the city is a reflection of collective life that strengthens social connectivity. Sacred places and shrines are an influential element in the construction and interconnectedness of Iranian cities. Religious shrines are the gathering places of different groups of people which link the flow of ceremonies and rituals. The purpose of this study is to investigate the position of Ali Ibn Mahziar’s tomb in the physical-spatial structure of Ahvaz and its effect on the formation of religious rituals, especially the mourning ceremonies of Tasua and Ashura within Ahvaz. This research is of descriptive-analytical type and employs methods of observation and field perceptions as well as reviewing the results of spatial arrangement analysis and graph modelling in order to study the adaptation of currents related to religious rites (for the movement of mourning delegations) and the existing city structure and especially the location of the shrine of Ali ibn Mahziar. Therefore, after field surveys, initial modelling was performed using graph theory approach and data analysis with centrality index and BC and DC scales, and then applying integration, connectivity and choice, space syntax analysis of Ahvaz city was implemented. The results show that the shrine of Ali ibn Mahziar plays a central role in attracting mourners from different parts of the city and strengthening social interactions and the presence of citizens. The focal position of the shrine in the configuration of the city reveals the close relation of this effective spatial element with the social patterns of the city, which over time, despite the changes, is still at the center of rituals and social interactions.

  One of the most common and relatively accurate methods for determining the amount of organic carbon in rocks in the oil and gas exploration potential is the Pyrolysis family, a standard example of which is the first rock pyrolysis method. Based on the study of the core, this method explores the potential of oil and gas resources in rocks. One of the important and valuable parameters in determining the potential of oil and gas resources is the determination of TOC. The purpose and motivation of this research is to compare the ΔlogR method and the mineralogy-based method for calculating the total amount of organic carbon in the source rock. It has the desired accuracy and relatively low cost. The fields studied in this study are two fields of Ahwaz and Rag-e sefid. These fields are among the potential fields of southwestern Iran for more detailed investigation and estimation of organic carbon content. In this research, software studies have been performed through IP software, using which the petrophysical data of each field have been calculated and compared, and finally, its results have been compared with actual TOC values. Input data in the mineralogical data method include density log, neutron porosity log and gamma log, and input data in the ΔlogR method include acoustic and resistivity logs. According to the fields, the most appropriate methods (in terms of R2) in Ahwaz and rag-e sefid fields are the mineralogical data method and the ΔlogR method, respectively. Also, in terms of cost, precision and accuracy parameters, the best method discussed in this research is R2 mineralogical data in Ahwaz and Rag-e sefid, 0.94 and 0.61, respectively. After this, the ΔlogR method comes second. Manuscript profile
