Hussein Al-Tuhoo ACKNOWLEDGEMENTS I have been indebted in the preparation of this thesis to my supervisor, Dr Maura Kelleher of Dublin Institute of Technology College, whose patience and kindness, as well as her academic experience, have been invaluable to me. I am extremely grateful ...

A conductive cable is a wire or a group of wires that conducts electricity. Substances which do not allow the passage of current through them are known as insulators. An insulating material should possess a very good dielectric strength and fire proofing qualities. In addition to good mechanical strength, it should have high chemical inertness. Often the most suitable insulation for resisting dielectric stress may not have an outer surface that is suitable for the conditions which the cable must meet. Thus, for improvement in resistance to flame, oil, abrasion, and chemical environment, a suitable jacket is extruded around the insulated conductor. ...

Patient face myriad safety issues while admitted to hospitals. These issues are of great concern to nurses and other parties involved. There have been significant sentimental events occurring continuously in healthcare whose bottom line base serious arguments since no one wants a patient to be injured or hurt in any way. It has become a responsibility to nurses and other participants in hospitals to provide proper healthcare for efficient tracking of severe sentiments that can cause harm. The frequent modernisations of hospitals such as the use of safety systems and enhanced technology in clinical record keeping have substantially lowered the causes ...

The question of paper versus plastic bags has long weighed on the environmentally-conscious. Determining what type of bag to use-- which type causes the least damage to the environment-- is a question whose answer could potentially change the way the world works. However, until relatively recently, the question of paper versus plastic remained unresolved. Through an analysis of paper and plastic bags, however, it can be seen that there are indeed benefits to using one over the other. To consider which type of bag is better for the environment, careful consideration regarding the manufacture, transportation, longevity, reuse, and disposal of ...

Polyvinyl chloride refers to the polymer that is third-most manufactured polymer. It is produced following a polymerization process using the vinyl chloride as the monomer (Patrick). The polyvinyl chloride is abbreviated as PVC and was accidentally produced Eugen Baumann, a chemist in France in the year 1835 and again in 1872 by Ivan Ostromislensky and his colleague Fritz Klatte. During the two incidents, the vinyl chloride was exposed to sunlight resulting in the production of a white solid in the flask where vinyl chloride was contained. Some of the major uses of PVC include in the construction since its more effective compared ...

Report on Vinyl Chloride

Report on Vinyl Chloride The case involves a man who went into a polymerization tanks measuring 8 feet in high and 5 feet wide. The man went into the tank alone at night, and there was no light in the pit. After 20 minutes, the man did not return, and somebody went to check him. The man was found lying in the pit. The person who was looking for the man climbed in order to get the man out, but the person was overwhelmed by the gas. The person immediately shut the open valve feeling dizzy. The person dragged himself ...

Cardiopulmonary bypass (CPB) remains the key technology for more complex cardiac operations. Despite tremendous progress since its introduction into clinical practice, CPB is still far from perfect and hence continuous efforts to study and improve hemocompatibilityof both conduct and components of CPB are crucial. The problem is cardiac surgery in conjunction with cardiopulmonary bypass in its current form restricts the patient to exit the hospital in 5-7 days. We know that conventional standard bypass triggers the release of inflammatory mediator which elongates patient’s length of stay. The Pinnacle System tricks red blood cells, platelets, proteins and inflammatory mediators ...
