Metals and corronslon - Lab Report Example These conditions are air and water. In test, tube II there was also more brown color indicating that rusting took place. Salt, air, and water favored the process of rusting. In test tube, III there was no observable color change on the oil. This is because the water was boiled which expelled all the oxygen. Secondly, the oil film prevented oxygen from entering the tube therefore rusting did not take place. The brown color was missing in test tube III. From the experiment conducted above, we can clearly conclude that the process of resulting requires the presence of water and air, which is oxygen to be specific. This is the reason why nails in test tube II and I ended up in brown color. Iron nail in test tube III did not rust due to the absence of oxygen (Holleman and Wiberg). Copper is the best conductor of electricity while it is also the most brittle. Brass, which is an alloy of copper and iron, is the harder of the two. Rusting can be prevented through various means. One of the methods to prevent rust is by oiling. Oiling prevents entry of oxygen, which is an essential condition necessary for rusting. Painting is also another possible means of preventing rust. Galvanization is the process of applying a coat of layer that is resistant to rust. This process also helps in preventing rust in metals. Method of storage is also amongst the simple ways in which corrosion can be prevented. Ensure that metals are stored in a cool and dry place to prevent rusting. In conclusion, water and oxygen are the necessary conditions for rusting to occur. The experiment was a complete success showing also the rate of conductivity between brass, copper, and iron. In summary copper is the best conductor of electricity as compared to brass and iron. Painting, coating, galvanizing, and method of storage are some of the ways that can be used to prevent the process of

Principles and Practice of Psychosocial Rehabilitation (mental Essay

Principles and Practice of Psychosocial Rehabilitation (mental nursing) - Essay Example It is reported that the rehabilitation unit helped Mr. Brayan to develop living skills such as cognition, using laundry, cooking food etc. Psychosocial Rehabilitation is the process in which the psychiatric patients are trained systematically to bring back them to the active participation in the society. â€Å"Psychiatric rehabilitation aims to improve the functioning and quality of life of individuals with psychiatricdisabilities due to serious mental illnesses†. (Rudnick 2003, p.1). â€Å"The strategies adopted for the management of schizophrenia may differ from one country to other country and may influence motivational readiness for change. For this purpose, rehabilitation approaches like vocational training, employment guidance, cognitive behavioural therapy, and psychosocial methods were included. In addition, issues surrounding gender differences, scarcity of resources, conventional medicine, and importance on family role were also need to be considered for the rehabilitation of patients.† (Review of Literature, p. 2.). The recovery is the objective of the psychosocial rehabilitation.

His functioning at home was very poor. He was not able to manage his finance and his condition make him vulnerable to the extend of exploitation by other. These conditions often leave him without sufficient money towards the end of each fortnight for basic necessities such as food and transport. He came to rehabilitation in need of help in Shellharbour Hospital to learn many skills like how to use kitchen for cooking, how to use the laundry etc. The case study further explains about the rehabilitation program that is carried out in the Mental
