Three hundred and eleven honeybee samples from 12 countries in the middle East and North Africa （mENA）（Jordan, Lebanon, Syria, Iraq, Egypt, Libya, Tunisia, Algeria, morocco, Yemen, Palestine, and Sudan） were analyzed for the presence of deformed wing virus （DWV）. The prevalence of DWV throughout the mENA region was pervasive, but variable. The highest prevalence was found in Lebanon and Syria, with prevalence dropping in Palestine, Jordan, and Egypt before increasing slightly moving westwards to Algeria and morocco Phylogenetic analysis of a 194 nucleotide section of the DWV Lp gene did not identify any significant phylogenetic resolution among the samples, although the sequences did show consistent regional clustering, including an interesting geographic gradient from morocco through North Africa to Jordan and Syria. The sequences revealed several clear variability hotspots in the deduced amino acid sequence, which furthermore showed some patterns of regional identity. Furthermore, the sequence variants from the middle East and North Africa appear more numerous and diverse than those from Europe.

Source Rock Evaluation and 1-D Basin modelling Approach for the Sargelu Formation, Atrush-2 Well, Kurdistan Region-Iraq

引用

Open Journal of Geology 2021年第3期11卷 49-60页

作者： Revan Akram ayad N. F. Edilbi Wrya J. mamaseni Govand H. Sherwani Nadhir Al-Ansari Department of Petroleum Technology Erbil Polytechnic University Kurdistan Region Iraq Department of Petroleum Geosciences Faculty of Science Soran University Kurdistan Region Iraq Department of Geology Salahaddin University Erbil Kurdistan Region Iraq Department of Civil Engineering Cihan University-Erbil Erbil Kurdistan Region Iraq Lulea University of Technology Lulea Sweden

The present study focuses on source rock evaluation of the Sargelu Formation by using core chips of rocks collected from well Atrush-2, Duhok, Kurdistan Region-Iraq. The Rock-Eval pyrolysis and vitrinite reflectance were executed. Subsequently, the selected parameters were used for source rock evaluation and 1-D Basin modelling calibration. The upper part of the formation mainly comprises argillaceous limestone with low content of organic matter (0.64% - 1% TOC). By contrast, the lower part is dominated with shale interval and contains high amounts of TOC values (>4% for 1272 - 1278 m) reveling good to very good quality source rock. Accordingly, good to very good hydrocarbon generation potential is suggested for this formation. Organic matter of the Sargelu Formation contains type II and mixed-type II-III kerogen. The values of Tmax and vitrinite reflectance (Ro%) demonstrate that the formation is thermally mature and in the oil zone. In order to construct a thermal history of the formation and determine the timing of hydrocarbon maturation and generation, the 1-D basin modelling Petromod 2019.1 was used in this study. Based on the 1-D Basin modelling simulation and its outputs, about 3500 m of overburden have been eroded at the study area. The present-day heat flow was found to be 30 mW/m2. The organic matter of Sargelu Formation entered the early oil zone in 64 ma and reached the main oil zone ca. 5 ma. The formation is still in the main oil zone at present-day. In well Atrush-2, the highest rate of oil generation for the Sargelu Formation was in the 8.5 ma, the onset of oil expulsion from Sargelu Formation was in 50 ma and the expulsion mass has been reached 0.5 mtons at present-day.

细胞因子是人体免疫系统功能状态的指标,在调节细胞信号传导,细胞分化,以及在免疫系统炎症反应中发挥关键作用。然而,这些细胞因子相关的免疫反应往往是非常快速动态的,而且在人体的浓度很低(pm)。因此,开发和研究能灵敏快速地检测活细胞分泌的细胞因子的分析方法对研究细胞免疫功能的微妙变化和动态特性至关重要。我们开发了一种基于细胞表面的酶联免疫吸附法,首先我们将细胞表面进行功能化,在细胞表面建立Sandwich型免疫生物传感器。这种细胞表面能够特异性地捕获细胞分泌的超微量的细胞因子,然后,将捕获的细胞因子使用荧光磁珠标记的检测抗体进行定量检测。我们对比了用FITC标记的检测抗体与用荧光磁珠标记的检测抗体用于检测细胞因子IL-6的检测特性。结果表明,用荧光磁珠标记的检测抗体的检测灵敏度更高(0.1 pg mL),它能灵敏地检测到单个活细胞分泌的IL-6。本文建立的检测方法可以用于细胞表面抗原的动态分析及癌症细胞的筛选,也适合于炎症疾病的早期诊断和治疗。

作者： ayad N. F. Edilbi Wrya J. mamaseni mahdi Kh. Aswad Bahroz Gh. Abdullah Falah Kh. Al-Jaboury Govand H. Sherwani Nadhir Al-Ansari Department of Petroleum Geosciences Faculty of Science Soran University Soran Kurdistan Region Iraq Geology Department College of Science Salahaddin University Erbil Kurdistan Region Iraq Geology Department College of Science University of Duhok Duhok Kurdistan Region Iraq Department of Petroleum Engineering College of Engineering American University of Kurdistan Sulaimaniya Kurdistan Region Iraq Petroleum Engineering Department Knowledge University Erbil Kurdistan Region Iraq Department of Civil Engineering Cihan University-Erbil Erbil Kurdistan Region Iraq Lulea University of Technology Lulea Sweden

Petrophysical properties of the Early Cretaceous Sarmord and Garagu formations from the Atrush and Sarsang Blocks in the Kurdistan Region are studied. These formations are generally composed of limestones and dolomitic limestones interbedded with thin to medium layers of yellowish-gray marl (calcareous mudstone). The current study shows that the average shale volume in the Sarmord and Garage formations is between 16% and 20%. In Atrush-1 Well, the average porosity ratio of the Sarmord and Garagu formations is fair to good (15% and 11%, respectively). However, in mangesh-1 Well, the porosity value is poor;it is around 4% on average. Generally, most of the hydrocarbons that have been observed within the pore spaces are residual oil type in Atrush-1 Well and movable hydrocarbon type in mangesh-1 Well. In Atrush-1 Well, out of 362 m thickness of both formations, only 180 m is considered to be a pay zone;whereas, the pay zone is just around 8.0 m thick out of 347 m of the total thickness. According to the calculated porosity values, the Garagu and Sarmord formations are not considered as good reservoirs in the studied wells, with the exception of Atrush-1 Well where the Sarmord Formation has fair potential reservoir characteristics.

Zubery Southern Technical University Technical Institute of Basra Environmental Pollution Research Unit Basra Iraq Southern Technical University University Presidency Basra Iraq Iraqi Ports Company Basra Iraq

The selection study for a sanitary landfill site at Basra city （south of lraq） indicated to choose Al-Barjesia region at chwabedian area which belong to AI-Zubair directorate, using global positioning system （GPS）. The measured latitude and longitude axes of this area are 30° 25.4＇ north and 47° 29＇ west. It is located at a distance of about 25 km straight line from the city center. The calculated elevation range of the chwabedian site was obtained to be 5-10 m above sea level, while the depth ofplutonic water in the landfill site is range from 15-25 m. The measured permeability for this site was about 0.75-0.84 mma/min. The evaluation of soil components percentage in the suggested site was listed in table 1, as examined by the international constructional laboratory, at Basra/Iraq. A primarily modern design for chwabedian sanitary landfill was projected and sketched in figure 3.
