Comparative test and study on different types of anchor cable support in high stress deep rock mass

Research Article of American Journal of Geographical Research and Reviews Comparative test and study on different types of anchor cable support in high stress deep rock mass Yu haikuo1, Zhang xiuyu1*, Li yuneng1, Chi en'an2,3, Pu hengqiang1, Ming yue1, Tang mingyuan1, Lu shuang1, Dai xianglong1 1Guizhou Guian Xinlian Blasting Engineering Group Co Ltd,Guiyang 550000,China. 2College of Ming,Guizhou University,Guiyang 550000,China. 3Poly Union Group Co Ltd,Guiyang 550000,China. To study the grouting anchor cable, high strength anchor cable, constant resistance, large deformation of anchor supporting of coal roadway surrounding rock different control effect, first using drilling into instrument detecting roof inner fracture of surrounding rock and loose circle development situation, again USES the anchor dynamometer, the roof abscission layer meter, convergence rule of surrounding rock of roadway convergence deformation and stress monitoring and supporting artifacts related to data processing and analysis between the drivage and stoping different anchor rope supporting of roadway surrounding rock under the condition of deformation and stress change rule anchor rope.Through the above steps, the grouting anchor cable is found to be the best supporting method.

ANALYSIS OF BOKO HARAM INSURGENCY ACTIVITES IN NORTH EASTERN NIGERIA: A GEOGRAPHICAL INFORMATION SYSTEM APPROACH

Research Article of American Journal of Geographical Research and Reviews ANALYSIS OF BOKO HARAM INSURGENCY ACTIVITES IN NORTH EASTERN NIGERIA: A GEOGRAPHICAL INFORMATION SYSTEM APPROACH Mustafa, Ibrahim Alhaji and Ezeamaka Cyril Kanayochukwu Department of Geography, Faculty of Arts and Social Sciences, Nigerian Defence Academy Kaduna, Nigeria Over the years, Nigeria as a Nation has been witnessing serious unrest characterized by the ethnic, political, farmer’s-herder’s conflict and activities of the insurgency. The north eastern geo-political zone of Nigeria was not left out of the activities. The activities of the Boko Haram insurgents has led to over ten thousand people losing their life and properties making many homeless. The paper is aimed at providing a comprehensive data and show the spatial distribution of activities of Boko Haram insurgency in Adamawa, Borno and Yobe States between 2009 and 2017. The paper utilizes secondary data from Armed Conflict Data (ACLED), printed materials, newspaper records, journals, and security agencies records. The method of analysis utilized in the study is Geographical Information System (GIS) approach using ArcGIS software and graphs to indicate the activities of the insurgency. The finding of the research shows that Borno State has the highest occurrence of insurgency and Yobe State recorded the lowest. The study concludes that the activities of the insurgents are more at the northern part and along the international boundaries.

Relationship among Ballast Water, Bioincrustration and Invasion of Exotic Species

Research Article of American Journal of Geographical Research and Reviews Relationship among Ballast Water, Bioincrustration and Invasion of Exotic Species EVANDRO VALENTIM DA SILVA, CARLA ANDREA DE MOURA, RITA DE CASSIA XAVIER DE CARVALHO, FÁLBA BERNADETE RAMOS DOS ANJOS Most species of seaweed that are transported through ballast water may have been transferred also by bioincrustration. Macroalgae of the genus Caulerpa, are native to the Mediterranean. C. taxifolia is an algae indicator of conditions, often harmful, and sometimes irreversible, to the ecosystems of the invaded areas. It is necessary to implement control measures to minimize damage to the endemic species and its im-pact on the areas of occurrence. This study aimed to assess the occurrence of exotic algae on and their relationship and distribution on the coast of Pernambuco, during periods of dry and rainy seasons from 2005 to 2009. Macroalgae were fixed in con-solidated and unconsolidated substrates, being also associated with other algae and even occurring as loose fragments in the sandstone reef. These fragments could be the result of anthropogenic activities or local hydrodynamics. The absence of sea ur-chins and other herbivores associated with C. taxifolia sites pointing to an allelopathic action in the process of colonization. We consider that Caulerpa taxifolia may have been introduced recently in our coast being in process of colonization growing itself most often in sandstone reefs, which suggests an action in inhibiting herbivory through the synthesis of allelochemicals.

THE UTILITY OF GEOSPATIAL TECHNOLOGY IN URBAN MORPHOLOGICAL STUDIES: A REVIEW

Review Article of American Journal of Geographical Research and Reviews THE UTILITY OF GEOSPATIAL TECHNOLOGY IN URBAN MORPHOLOGICAL STUDIES: A REVIEW Maurice Onyango Oyugi School of the Built Environment, Department of Architecture and Building Science, University of Nairobi, Nairobi, Kenya. Increasing urbanisation, poor location of urban amenities and utilities in consideration to population concentration has made many cities face environmental, land use and socio-economic challenges. This can be mitigated against through the analysis of the interactions existing between urban natural and human systems as provided for by the geospatial technology notably Remote Sensing, Geographical Information Systems (GIS) and Photogrammetry. This has made geospatial technology gain primacy in the urban studies and literature on the utility of geospatial techniques in the analysis and modelling of urban morphology has grown over the years. This paper therefore, anchors an understanding on the urban morphology and the role of geospatial techniques in studying the same. Keywords: Geospatial Technology, Urban Morphology, Land Use and Land Cover ...
