Ethical and moral dilemmas in regards Ebola Research Paper

Ethical and moral dilemmas in regards Ebola - Research Paper Example Here in this study ethical and moral dilemmas of the disease around the world will be analysed. The study will include research question or objective, methodology and findings and analysis. Research question is significantly important and an integral part of any research paper. Research question helps the researcher to build a whole research report. It poses lots of questions that other people care about. According to Bordage and Dawson, research question is one of the most important components of any research paper. It provides a clear picture about the research topic. Research question guides the research outcome. Without the help of research question a research paper cannot find the proper direction. Here in this case the research question is whether the world is facing ethical and moral dilemmas related with Ebola. According to Enemark & Selgelid, (2012), ethical and moral dilemmas are quite evident in the cases of various infectious diseases. They have stated that ethical and moral dilemmas are not new factors as far as the infectious diseases are concerned. It is an age old issue that the global fraternity is facing since long. The authors have categorically stated that nurses and doctors are also human being. They have the equal chances of being impacted by the infectious diseases. But on the other hand healing patients is the fundamental objective for the doctors and nurses. So there is a huge scope of ethical and moral dilemmas. According to them these kinds of ethical and moral dilemmas are common and automatic in nature. There is nothing astonishing into it. It is often being noticed that patients affected by the infectious diseases are generally being kept at the isolation chambers where entry and exists are restricted. The authors have stated that doctors and nurses take extra precaut ions before entering into those isolation chambers. But still there remains a sense of moral and ethical dilemma. Doctors and nurses feel

Concrete; this is a hard, compact material used for building, and is formed by a mixture of gravel, cement, water, and sand when they undergo hydration. Cure; this is the act of keeping concrete moist on the initial hardening. Deformation; changing the dimensions of structures using a force. Dormancy period; the period that concrete retains it workability. Elasticity; The capability of materials to retain the original shape after getting stretched. Forms; are the holders where concrete is placed during hardening. Hydration; reaction of water with cement to form a cement paste. Mortar; is a Cement paste that has been mixed with sand. Pozzuoli cement; is a Volcanic rock powdered, used for making hydraulic cement. Portland cement; this is a cement consisting mainly of calcium silicates react with water forming a hard mass. Workability; this is how easily fresh concrete can be plac ed and consolidated in forms. 3.0 Text. 3.0. Introduction to Concrete. Concrete, can be defined as a composite material used in construction composed mainly of aggregate, water, and cement. It has several formulations, which give properties that tend to vary. This aggregate consists crushed rocks or coarse gravel like granite or limestone this is mixed with other fine aggregate like sand. Cement, usually the Portland cement, and Cementitious materials like slag cement and fly ash are used as a binder in the aggregate. Many chemical admixtures may also be included in order to come up with these varied properties. Liquid normally water is added and mixed with this dry composite, this enables the concrete to be poured (shaped) before solidified...Cement, usually the Portland cement, and Cementitious materials like slag cement and fly ash are used as a binder in the aggregate. Many chemical admixtures may also be included in order to come up with these varied properties. Liquid normally water is added and mixed with this dry composite, this enables the concrete to be poured (shaped) before solidified and hardened to come up with a rock-hard strength through a process known as hydration. The liquid applied reacts with the cement, forming a bond with other components, finally forming a tough stone-like material. It has a comparatively high compressive strength, nevertheless much lesser tensile strength. It is against this that it is reinforced using other materials which are very strong in tension like steel. Processes that can damage the concrete include freezing of the trapped water. It is widely used in walls, pavements, brick/ block, foundation, bridges/ overpasses, footings for gates, and even boats. Some of the most famous concrete buildings or structures are like the Burj Khalifa (world's tallest building), the Panama Canal, the Hoover Dam, and the famous Roman Pantheon.
