The Stochastic Finite-Fault Modeling Based on a Dynamic Corner Frequency Simulating of Strong Ground Motion for Earthquake Scenario of North Tabriz Fault

The occurrence of the historical and machine Earthquakes, near to the North Tabriz Fault in NW Iran is an evidence for the seismic activity of this fault, which records a historical earthquake with a magnitude more than 7. Using the existing experimental relations, seismicity, and the fault geometry, a Mw 7.7 earthquake scenario was defined. The stochastic finite-fault modeling based on a dynamic corner frequency shows good agreement with common attenuation patterns. The shake map illustrates that Baghmisheh, Roshtieh, Ellahieh, Valiamr, and Eram region on Tabriz are at high hazard areas, and the maximum acceleration is located at the north direction with the same azimuth similar to fault strike.

Soil Salinity and Alkalinity Map Preparation Based on Spatial Analysis of GIS (Case Study: Tabriz Plain)

Better management of agricultural fields is related to valuable information which can derived from soil salinity and alkalinity maps. These maps are considered as one of the most important factors which restrict plant growth as well as decline crops yield. The objective of this research was preparing of soil salinity and alkalinity maps in Tabriz plain over 50,000 hectares based on different techniques of spatial analysis in GIS software. For this mean, study area was divided in 1500 × 1500 m2 grid cells. Then, geographical coordinate of each grid recorded in UTM system. So, they were transferred into GPS for navigating to the exact excavation location. After soil sampling and transferring to the lab, their EC and PH were measured in saturation extract of soil samples. So, spatial distribution of soil sampling points was prepared in form of point map by GIS software. Generalization of point information to surface was performed using different interpolation algorithms and based on standards of Soil and Water Research Institute. Accuracy of interpolated maps was evaluated due to the MAE and MBE values. The results showed that the lowest observed error is related to the Spline method and therefore, this method was used for spatial modeling of salinity and alkalinity maps in the intended area. The research findings demonstrated that from total of 50,000 hectares, only 3066 hectares were without salinity and alkalinity limitation (6.1%), 9066 hectares had low salinity and alkalinity (18.1%);17,772 hectares had average limitation for salinity and alkalinity (35.6%) and the remaining 20,096 hectares had high and very high limitation for salinity and alkalinity.

Spatial Analysis Applied for Gas Theft Modelling in Tabriz City, Iran

Unauthorized use of energy is the major source of the non-technical losses of the energy in developing countries. Gas theft as a kind of energy theft is an increasing issue in a number of countries particularly in developing countries. This study is an attempt to address the issue of gas theft through the deployment of Geographic Information System (GIS) capabilities (Spatial Analysis) to import external factors into the current gas theft detection methods, improve data mining processes, and offer some management solutions. To achieve the intended goals in the study, two types of data sources were collected and analyzed: internal data such as reported instances of gas theft, and some customer properties, and external data such as some demographic data. In order to analyze and modeling the gas theft and the relationships between variables we used Hotspot analysis, Ordinary Least Squares regression (OLS) and Geographically Weighted Regression (GWR) analysis with ArcGIS tools. The results from clustering test indicated that the gas theft is not a random phenomenon in all areas of Tabriz and there are underlying factors. Mapping clusters by the hotspot techniques suggested the locations of clusters and areas at risk. The results of the regression analysis illustrated the importance of external factors clearly. According to the results, we recommend a conceptual GIS framework to select high risk areas as a subset data for a meter data analysis. Results of this research are of great importance for GIS based spatial analysis and can be used as base of future researches.

Paleo and Modern Stress Regimes of Central North Tabriz Fault, Eastern Azerbaijan Province, NW Iran

The North Tabriz fault is a segmented dextral fault in Northwest Iran, with a history of major destructive earthquakes that have repeatedly destroyed the city of Tabriz（current population 1.6 million）. The quiescence of the fault（last major temblor in 1854） and a lack of outcrop study have hampered stress analysis. Resolution of the stress states on the fault could be used for seismotectonic study along the North Tabriz fault and for understanding the geodynamics of the Arabia-Eurasia collision zone. Using fault-slip data collected from 88 localities in the fault system, we conducted an inversion analysis of this fault-slip data and analysis of the stratigraphic, geometric, and structural information. As a result, we confirmed that transcurrent deformation is prevalent on the North Tabriz fault and adjacent areas and is generally accomplished by predominant NW-SE-trending dextral and NE-SW-trending sinistral faults. Specifically, three separate tectonic episodes are recognised from the stress inversion data, consistent with the geologic data：（i） a post-Cretaceous and pre-Early Miocene compressional（Laramian） stress regime,（ii） an Early Miocene extensional stress regime, and（iii） modern tectonic episode with different local stress regimes（compressional and extensional） along the different segments of this fault.

Serologic survey of cytomegalovirus and rubella virus in Tabriz,Iran

Objective:To determine the prevalence of rubella and cytomegalovirus(CMV)among women in Tabriz City,Iran in 2013.Methods:This study was carried out in numerous laboratories in city of Tabriz.In 2013,26618 women aged 18-35 years were enrolled in this study.Serum samples were analyzed with chemiluminescence apparatus and SPSS software was used to conduct the statistical analysis.Results:A total of 26618 individuals were examined(10598 cases for anti-CMV and 16020 cases for anti-rubella).About 98.9%and 1.1%samples were reported positive and negative for CMV immunoglobulin G(IgG),respectively.The positivity for anti-CMV immunoglobulin M(IgM)antibody was found in 0.75%samples,while 99.25%were negative for the anti-CMV IgM antibody.Anti-IgG against rubella seropositivity was found in 95.8%and rubella IgM seropositivity in 0.93%.Anti-IgG against rubella seronegativity was found in 4.2%and rubella IgM seronegativity in 99.07%.Conclusions:According to the results,primary and secondary infections are usually symptomless or inconspicuous,but they can cause serious fetal damage.Routine antenatal care should therefore include serological testing to check the immune status of the woman and to diagnose any fresh virus infections that may arise.

Prevalence of bacterial agents isolated from clinical cases of bovine mastitis in the dry period and the determination of their antibiotic sensitivity in Tabriz,Iran

Objective:To determine the prevalence of mastitis-causing bacteria in the dry period and its antibiotic sensitivity.Methods:In this study,852 dry cows were examined.A total of 30 cows with clinical mastitis symptoms were detected and their milk samples were collected.In order to purify the bacteria,brain heart infusion and blood agar media were applied and single colonies were used for Gram staining,oxidase and catalase testing,cultivating in O-F medium to determine the genus and species of bacteria.Then,antimicrobial susceptibility was tested by the agar disk diffusion method.Results:The prevalence of isolated bacteria was 2.46%,in which coagulase positive Staphylococcus,coagulase negative Staphylococcus,Streptococcus dysgalactiae,Streptococcus faecalis,Escherichia coli,Pseudomonas,Bacillus and yeast were(9/99)%,(6/66)%,(13/32)%,(3/33%),(6/66)%,(13/32)%,(9/99)%and(6/66)%,respectively.After tests of antibiotic susceptibility,the most and the least sensitivity were reported to enrofloxacin and ampicillin respectively.Conclusions:This study indicated that Streptococcus dysgalactiae is the most commonly isolated bacteria with the greatest sensitivity to enrofloxacin and tetracycline which can be used to treat mastitis in the dry period in Tabriz.

东方造境:波斯细密画中的中国风——以大蒙古《列王纪》为例

伊尔汗国时期,大不里士画派中的细密画展现了浓厚的中国风,尤其是艺术成就最高的手抄本—大蒙古《列王纪》。文章以该手抄本为对象,主要研究了中国风在其中的具体表现及伊朗人打造东方风景画的渠道。研究结果表明,波斯细密画的中国风,并非对中国元素进行了简单的复制和挪用,而是中国文化与伊朗文化(包括琐罗亚斯德教与伊斯兰教信仰下的文化)相互调试后的艺术结果。

15至16世纪伊朗家具装饰品中的宗教角色

本文以伊斯兰教及相关艺术为研究对象,探讨十五世纪家具设计元素。伊朗和伊斯兰教的统治从萨珊时代开始,直到后来形成萨法维王国,伊斯梅尔国王才使得伊朗正式成为了一个伊斯兰国家。在这个时期,艺术和文化逐渐进入伊朗,并被改良成伊朗伊斯兰教的版本。建筑设计受到的关注最多,因为清真寺象征着国家宣扬的相关艺术,如瓷砖、伊斯兰装饰和伊朗元素,这些是与其他穆斯林地区不同的萨法维艺术。这些很明显地反映在国王造办处制作的《列王纪》的微缩图中,是伊朗大不里士市15世纪伊朗家具设计史上最重要的参考史料。
