An Evaluation of Cracks Repairing Techniques in Metals
Abstract: Cracks are surface that develop in a material. Dissemination energy derived from mechanical, thermal, chemical, and metallurgical effects, or a grouping of these may affect crack beginning and growth. Numerous types of cracks exist in metals and can be characterized as grinding, solidification, cooling, crater, machining tears, plating, centerline, pickling, heat treatment, fatigue, creep, stress corrosion and hydrogen cracks. Cracks can grow and lead to complete fracture of the component …

Plastics Compressive Strength Testing
Abstract: Compression test is a mechanical test that determines how much compressive force a material to resist before cracking. A gradually applied load compresses the test item, which is commonly in the shape of a square, pyramid, or cylinder, between the platens of a compression-testing machine. Many ductile metals, such as mild steel, have extremely high compression strength, yet measuring them is challenging. Whenever a load is given to a ductile …

Review of Composites formed of Thermoplastic as Organic Fibers
Abstract: Composites made of structural monomers gave rise to thermoplastic polymers (TMCs). Due to their usage of a thermoplastic matrix, these materials really aren't chemically reactive. TMCs may be remoulded without degrading when heated and become softer. They harden into the final shape when they cool. Thermoplastic materials bonded with plant fibers may one day be used to create impact- absorbing structure for renewable power. Its impact features of organic fiber-reinforced …

Predictive Model on Constant Pressure Drop Variable: Area Fluid Flow System in a Pipe
Abstract: The effect of density, pressure drop, and orifice area was examined in this research. The basic equation developed to represent steady-state fluid flow is the Bernoulli equation which assumes that the total mechanical energy is conserved for steady incompressible, in viscid, isotherm flow with no heat transfer or work done. These restrictive conditions can actually be representative of many physical systems. The Bernoulli’s principle was applied in explaining the design …

Fatigue life Analysis of High Pressurized Gear Pump Component—A Review
Abstract: This review deals with fatigue life analysis of high pressurized gear pump component. The gear pump components failure occurs at the root of the driven gear and uneven wear at driven side of thrust plate. To avoid the failure, pump should pass the endurance test condition without fail, the test condition should not drop volumetric efficiency more than ten percentile, should pass high cycle fatigue life. The system is to …

Renewable Energy Technologies for Future and Sustainable Development
Abstract: People are relying upon oil for primary energy and this will continue for a few more decades. Other conventional sources may be more enduring but are not without serious disadvantages. The renewable energy resources are particularly suited for the provision of rural power supplies and a major advantage is that equipment such as flat plate solar driers, wind machines, etc., can be constructed using local resources. Without the advantage results …

Research Insight: Earthquake Resistant Structures in Construction Sector
Abstract: It is normally unpredictable to reckon uncertain seismic activity, but hopefully advanced Earthquake warning systems have been developed that can provide regional notification of an earthquake in progress, that provide timely alerts to the mass but before the ground surface has begun to move, potentially allowing people within the system's range to seek shelter before the earthquake's impact is felt. More to the plate is the attempt to create earthquake …

Assumptions, Limitations and Applications of Bernoulli’s Equation
Abstract: The Euler-Bernoulli beam theory, also called “beam theory”, is a condensed version of the linearisotropic theory of elasticity and can be used to predict the load-carrying and deflection properties ofbeams. It was initially stated around the year 1750, but it was not widely used until the Eiffel Towerand the Ferris Wheel were built in the late 19th century. It immediately became an engineering pillarand a catalyst for the Second Industrial …

A Brief Overview of Disseminated Intravascular Coagulation, its Etiology, Clinical Manifestations, Pathophysiology, and Management
Abstract: DIC is the short form of disseminated intravascular coagulation. Disseminated intravascular coagulation (DIC) may be defined as a generalized hypercoagulable state that leads to blood clotting in microvascular and macrovascular system of the body. This compromised blood flow, to multiple organs and tissues ultimately results in multiple organ dysfunction syndrome or MODS. DIC arise when the proteins that control blood clotting becomes overactive. Though it is a life threatening condition …
