| 1 | A new analytical solution for calculation the displacement and shear stress of fully grouted rock bolts and numerical verifications显示文摘In presence of difficult conditions in coal mining roadways, an adequate stabilization of the excavation boundary is required to ensure a safe progress of the construction. The stabilization of the roadways can be improved by fully grouted rock bolt, offering properties optimal to the purpose and versatility in use. Investigations of load transfer between the bolt and grout indicate that the bolt profile shape and spacing play an important role in improving the shear strength between the bolt and the surrounding strata. This study proposes a new analytical solution for calculation displacement and shear stress in a fully encapsulated rock bolt in jointed rocks. The main characteristics of the analytical solution consider the bolt profile and jump plane under pull test conditions. The performance of the proposed analytical solution, for three types of different bolt profile configurations, is validated by ANSYS software. The results show there is a good agreement between analytical and numerical methods. Studies indicate that the rate of displacement and shear stress from the bolt to the rock exponentially decayed. This exponential reduction in displacement and shear stress are dependent on the bolt characteristics such as: rib height, rib spacing, rib width and grout thickness, material and joint properties. | Ghadimi Mostafa Shariar Koroush Jalalifar Hossein | 2016 | International Journal of Mining Science and Technology2016,26,6: | 7 |

| 6 | Evaluating land subsidence by field survey and D-In SAR technique in Damaneh City, Iran显示文摘Based on the data from piezometers, well logs, geophysical surveys and the interferometric synthetic aperture radar(In SAR) technique, this study investigates the main causes of land subsidence in Damaneh City, Iran. The size, openings and direction of fissures were measured by micrometer and compass. The locations of fissures and wall cracks were determined by GPS. The geoelectrical data were used to determine the composition, thickness, depth and shape of lower parts of the aquifer. Groundwater fluctuations were evaluated by available piezometers. The In SAR technique was used to measure land deformation from space and to map the dense changes of surface displacements. The results indicate that the main cause of ground subsidence is the decline of groundwater heads and changes in composition and thickness of compressible lacustrine sediments. The subsidence map obtained from the radar data of ASAR sensor of ENVISAT satellite shows that the subsidence zone is mainly in northern city that is underlain by very thick fine sediments. The subsidence rates from March to December 2005 and from July 2011 to January 2012 are 6.7 and 7.0 cm/a, respectively. The results also show good correlations among the formation of earth features, decline in groundwater head and thickness of fine-grained sediments. We recommend that the groundwater withdrawal for agricultural and industrial sectors should be restricted and urban expansion in the northern part of the city should be constrained. | Akbar GHAZIFARD Elham AKBARI Koroush SHIRANI Homayon SAFAEI | 2017 | Journal of Arid Land2017,9,5: | 1 |

| 12 | 紧凑一体化中型压水堆设计显示文摘近几年,为了消除冷却剂丧失事故和减少核电厂大型容器的数量,反应堆结构和系统布置出现了一体化的形式。本文主要研究如何在给定容器体积的条件下进一步增加反应堆的功率。这一方法被应用于国际革新安全反应堆(IRIS)——种热功率为1000MWt的中型轻水堆中。IRIS采用一体化设计,所有的泵、螺旋管式直流蒸汽发生器(OTHSG)和传统压水堆(PWR)的堆芯都被包容在反应堆压力容器内。本文检验了在维持或提高安全裕量的同时,对于相同尺寸的压力容器增加功率输出的想法。提出了使用印刷电路板式热交换器(PCHE)和内、外两面冷却环状燃料(IXAF)一同作为对IRIS设计改进的方案。用RELAP5和VIPRE程序对采用这一改进方案的反应堆进行了稳态和瞬态工况下的模拟,结果表明使用了PCHE和IXAF的IRIS反应堆功率可提高50%。上述设计可以降低发电成本,并且这些改进和分析可以应用于任何一体化反应堆的设计。 | Koroush Shirvan Pavel Hejzlar Mujid S.

| 13 | Molecular detection of Leishmania isolated from Cutaneous leishmaniasis patients in Jask County,Hormozgan Province,Southern Iran,2008显示文摘Objective:To investigate on patients leishmanial infections in Jask County.Methods: Impression smears were prepared from patients in 2008,all,were chequed for leishmanial infection by microscopy and molecular assays.Whole D.NA was extracted using Proteinase K and Phenol/Chloroform/Isoamyl alcohol method.The variable segment on minicircles of kineloplasl DIVA was amplified via a Nested-PCR technique using species-specific primers(LIN R4-LIN 17 -Lin 19).Results:A total of 40 smears were prepared from 20 patients,from which,eight samples (40%) were positive for leishman body by microscopic method,while,18 samples(90%) were positive,molecularly.The parasite was identified as Leishmania major(L major).Conclusions: Zoonotic or Rural cutaneous leishmaniasis is endemic in Jask County whose pathogen is L major.Molecular assays using specific primers are very accurate and more sensitive and specific than microscopy which is time consuming and needs master mieroscopists. | Koroush Azizi Aboozar Soltani Hamzeh Alipour | 2012 | Asian Pacific Journal of Tropical Medicine2012,5,7: | 0 |
