Effect of Reinforcement on Bearing Capacity of Sand
Abstract: The reinforced earth concept, which is now being evaluated with increased significant encompasses formation of a composite of a soil with tension resistance reinforcing elements such as metallic and nonmetallic strips, bars, rods fibers or nets in the soil. The objective of using the reinforcement is to supress the normal tensile strains in the soil mass through frictional interaction. Flexible nature of reinforced earth mass enables it to withstand large …

Analysis of Vibrational Induced Structure Considering Rail and Seismic Load Using ETABS
Abstract: In the past, buildings next to railroad tracks were not taken into account when designing them, which resulted in catastrophic damage to the buildings as well as fatalities. For these structures to be designed safely, the vibrational loading must diminish. This study's case study is the Rani Kamlapati railway station in Bhopal, which was renovated by the Bansal Group and is the nation's first private railroad station. They suggested building …

Creep Analysis Characterization and Study of Biodegradation Effect on Compression Molded LDPE/Cellulose Composites
Abstract: AbstractSynthetic polymers are important industrial materials, but their everyday use is hazardous to the environment. The solution to this seems to lie in modification of their structure through blending with biopolymers. Low density polyethylene (LDPE) and Cellulose were used in sample preparation for research in this work. LDPE/starch composites have undesirable properties and so there was need to explore LDPE/cellulose composites and evaluate their susceptibility to primary biodegradation. Compression molded …

Natural Gas Hydrate: A Brief Review
Abstract: Hydrates are often called as a future fuel or frozen fuel. There is an abundant source of natural gas deposits as compared to the conventional deposits. The reservoirs of the natural gas hydrates have been strongly suggested as a potential energy resource. These resources have the potential of displacing the position of conventional hydrocarbons from the energy dealing markets when trapped within the water molecules. This is possible only when …

Review of Subsea Pipeline for Minimizing Thermal and Pressure Expansion
Abstract: As the offshore oil and gas fields have been exploited in deeper water, subsea pipelines are required to operate at high temperatures and pressures. It causes subsea pipelines to be more subject to movements both in lateral and axial directions due to the loads produced by high temperatures and pressures. Some high temperature pipelines have experienced the cumulative axial displacement of an overall pipeline length over a number of start-up/shut-in …
