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 …

The Influence of Hexanol and Methyl Acetate as Oxygenated Additives with Diesel Fuel in a Diesel Engine Generator
Abstract: Diesel engines play a vital role in all the major sectors (such as transportation and industrial) due to their high efficiency, durability, reliability and low operating cost. At the same time, they are considered as one of the biggest contributors of environmental pollution by releasing enormous amount of toxic gases to atmosphere (such as NOx, HC, CO2 and PM). Emissions from transport, especially motor vehicles, increase the level of gases …

Ship Collision analysis of tanker using finite element method at high and low impact velocities
Abstract: The aim of this paper presents a study of ships collision to improve crashworthiness of double side tanker ships and minimize accidental oil spills in the event of collision. Structural design of ships against collision requires prediction of the extent of damage to ship structures subjected to impact. Ship design against conventional loads such as shearing, bending and local buckling and the accidental loads requires applying different stiffening systems for …

Biopsychosocial Approach in Asthma
Abstract: The bio-psycho-social model of health and illness proposed by Eagel (1977) [P1] implies that behaviours, thought and feelings may influence a physical state. The basic principle says that the person suffers as a whole and not as isolated organs. In holistic approach to wellness, we should consider the personality, the emotional dimensions and the socio- environmental condition of the patient. As asthma is a controllable disease, the aim of asthma …

A Study to Assess the Knowledge Among Nursing Officers Regarding the Management of Post-exposure Prophylaxis of Blood and Body Fluid in Selected Multi-speciality Hospitals of New Delhi
Abstract: Introduction: Nurses are at an increased risk of contracting HIV due to occupational exposure through needle stick injuries and contact with blood or bodily fluids, particularly when caring for HIV-infected patients. As a result, post-exposure prophylaxis (PEP) for HIV has become critical among nurses. Globally, the annual incidence of HIV infection is decreasing, but at the end of 2010, approximately 34 million people were still infected with HIV. In India, …
