Abstract: Fenchuganj gas field is located at Surma Basin and 40 km south of Sylhet town. This field is operated by Bangladesh Petroleum Exploration and Production Company Limited (BAPEX). Gas properties analysis is essential for gas production designing, gas processing, gas transportation and gas handling systems. This study covers the mathematical and graphical calculation to analyze several properties of gas such as molecular weight, gas gravity, gas compressibility factor, gas formation volume factor, gas expansion factor, gas density and gas viscosity of Fenchuganj gas well,......

Abstract: Twenty (20) Vertical electric soundings (VES) were acquired in Obigbo main dumpsite Portharcourt to delineate the subsurface geology of the area for groundwater development, and thereafter the geoelectric data was converted into relevant hydrologic properties of aquifer (transverse resistance and longitudinal conductance) for aquifer characterization. Interpretation of the twenty (20) VES profiles showed three (3) lithologies which are topsoil, clay and sand, with sand acting as the main aquifer unit. 1D geologic sections computed from the resistivity interpretation showed that the aquifer system in the area consists of unconfined and confined aquifer units within the second,......

Abstract: The failure rate recorded in most groundwater projects has informed the general acceptance of geophysical survey as a prerequisite to any successful water well project. The Vertical electrical sounding (VES) technique is extensively gaining wider applications in environmental, groundwater and engineering geophysical investigations. Geological studies of the Masuri area and its environs indicated biotite granite, granite-gneiss and rocks of the Keri-Keri Formation as the major rock types. A total number of 14 VES locations designated for the hydrogeological studies have indicated the predominance of consolidated formations with primary porosity but lacking......

Abstract: In present, the engineering structures such as buildings, tunnel walls, bridges, railroad tracks are monitored for ensuring early warning of structural failure. The displacements of the structures are measured currently by using accelerometers, GNSS and geodetic total stations. In this paper, the monitoring and analysis results of displacement, which are created by the underground parking construction locates in Kağıthane-Yeşilce District (Istanbul, Turkey), on the surrounding buildings by using total station are presented. Total station is a measurement device which defines the coordinate of a point indirectly from measured angles and distances. Total station measures the distance by using the travel time of a light wave for reaching a point (monitoring prism) and reflecting back. In this study, 20 monitoring prisms were mounted to four surrounding buildings of the exaction area. The buildings were monitored for 13 days (from 06.07.2017 to 29.07.2017) and the interval of the measurements was 20 hours. Finally, the displacements of the buildings are found generally at north directional and 2D and 3D displacements are monitored in the buildings.

Abstract: The interpretation of 12 Schlumberger vertical electrical sounding (VES) data was carried out to investigate the electrical properties of soil and how it can contribute to gully formation. Terrameter Signal Averaging System (SAS) model 300 was used in the absence of any signal enhancer as the expected targeted depth to be investigated is within the range of penetration of the instrument. During this data acquisition, readings were taken using maximum electrode separation of 400m, with layer resistivity values at 65.168Ωm and 44800Ωm for both minimum and maximum values respectively. The depth and thickness values of layers under investigation were also taken and have.......

Abstract: In this study, support vector machine (SVM) as a more accurate method was used to classify remote sensing images and analyze the dynamics and spatiotemporal process of regions. The study area is Yanji City. Taking five years as a time span, remote sensing images from 2007 to 2017 are downloaded. Geometric registration, clipping and other processing are performed in ArcGIS for the raw data. The color feature and texture feature of the processed remote sensing image data are extracted and the training set is established. According to the concrete analysis, kernel function is needed to establish the training model based on the training set data. There are four kinds of kernel functions in common use, and the radial basis kernel function is determined by comparing the classification accuracy......

Abstract: The Beni Suef Basin is a petroliferous rift basin straddling the River Nile including a thick Mesozoic–Paleogene succession. It is bisected by the major course of the River Nile Valley into two provinces; West of Nile province (WON) and East of Nile province (EON). The Cretaceous succession in Beni Suef Basin can be subdivided into two main megasequences; Lower Cretaceous Megasequence and Upper Cretaceous Megasequence. Seismically, the Lower Cretaceous Megasequence comprises two seismic facies and displays a general sheet-like to wedge-shaped geometry. It includes seismic facies displaying chaotic to parallel reflector configuration with variable continuities and amplitudes......

| Title | : | National Movement and the RSS |

Abstract: The role of RSS in the national movement against the British rule was not an issue in the first five decades of the independence of India. This issue became hot for the critics of the RSS when Atal Bihari Vajpayee issued a postage stamp commemorating Dr. Keshav Baliram Hedgewar, the founder of the RSS, as a great freedom fighter, on 18th March 1999. Some writers like Shamsul Islam argue that RSS never took part in the anti-imperialist struggle. A prominent Communist Party of India (Marxist) leader Sita Ram Yechuri in his write-up "What is Hindu Rashtra?‟ said that "it virtually boycotted and at times opposed the freedom struggle.‟ Almost similar claims were also made by Sumit Sarkar (Marxist historian) and many other Communist leaders and some Congress leaders of India. It is believed that these leaders and historians have manipulated the truth, distorted facts and misinterpreted historical events....
