How to use a Gold in Wind Turbines Essay Example | Topics and Well Written Essays - 1250 words

How to use a Gold in Wind Turbines - Essay Example This report focuses on wind turbines, their design and how they can be redesigned using gold in order to increase their efficiency. Introduction The use of wind turbines to harness wind power is not a new technology. It is a concept that has been in operation since as the 7th century. To date, the wind turbines have become a familiar picture with their purpose being simple: to harvest the energy possessed by wind. Wind turbines differ in size depending on the required amount of energy. All wind turbines are made up of 4 major parts; rotor blades, nacelle unit, base and tower ((Energy Center of Wisconsin 1). However, due to the technological advancements, various changes are been made in the design and choice of components in an attempt to increase its efficiency. The following report explains how gold can be used in a wind turbine in order to increase its efficiency. Breakdown of the major parts of a wind turbine As stated earlier, wind turbines come in different sizes depending on t he energy requirements. There are four crucial parts that are essential in any wind turbine. These are rotor blades, nacelle, support tower and the foundation/base as shown in the following figure. Figure 1: The major components of a wind turbine system (Alternative energy eMagazine 7) 1. ... Rotation of the blades makes the turbine rotate thus capturing the kinetic energy contained in the wind (Energy Center of Wisconsin 2). 2. The Nacelle This part can be referred to as the ‘engine system’ of the wind turbine. It houses the generator and the gearbox that are connected to the rotor blades through a shaft and system of gears. The gears are used to increase the rotation speed of the blades. Rotation of the blades results in rotation of the generator. The generator converts the kinetic energy possessed in the wind into electrical energy (Energy Center of Wisconsin 3). 3. Support Tower They are elevated a few feet from the ground and are used to hoist the rotor blades and the nacelle unit to heights where there is likely to be little barriers to wind motion. The most common design is a round steel cylinder. It also houses the electrical conduits and also contains a ladder running outside it to provide access to the rotor blades and nacelle unit for maintenance a nd repair services (Energy Center of Wisconsin 4). 4. Base/Foundation The base is constructed using concrete that is reinforced with steel bars. The foundation holds the entire system in position thus is constructed with utmost caution. Choice of Materials for each component 1. Rotor Blades As stated earlier, the blades may be made from fiberglass, plastic, or metal. Regardless of the material used, the blades must be designed to capture the maximum surface area of the wind. They are also designed using a light weight material that is also durable and corrosion resistant. For this reason, most blades are made from reinforced plastic and fiberglass (Layton 5). 2. Nacelle unit In this unit, the major components are the generator and the gear box

Scholarly paper schizophrenia Essay Example | Topics and Well Written Essays - 2250 words

Scholarly paper schizophrenia - Essay Example A holistic approach has to be adopted in the treatment of this condition. Although schizophrenia cannot be cured, its symptoms can be considerably mitigated by medication with antipsychotic drugs. To a significant extent, this condition is genetic. However, it is also caused by stress, abuse of drugs and trauma. Schizophrenia Introduction This work deals with the disorder of schizophrenia and the methods of dealing with the problem. Initially, clinical features of the disease were taken up for a discussion. Subsequently, implications of the disorder were discussed. Moreover, the psychopathology of this ailment had been analysed. In this regard, role of the health care professionals in implementing the pathological interventions related to the patient, had been examined. Thereafter, the impact of the disease on the psychological condition of the patient were examined. The extant medical treatments and their effectiveness have been analysed. Pharmacological treatments, and psychologica l interventions provided by the health professionals, as a part of the treatment of this disorder, were taken up for a brief discussion. Subsequently, genetic issues relating to the problem were examined. Finally conclusions were arrived at stating that family support and psychological interventions are essential, n addition to the available medical treatments, in containing the degenerative disorder schizophrenia. Schizophrenia is a condition that can be correlated to many factors, and constitutes the result of a combination of genetic and environmental factors. Although the exact causes of this disorder have not been established, it is now evident that some of the genetic conditions have a causal relationship with schizophrenia, as depicted in the research conducted by Tandon, Keshavan, and Nasrallah. This can be established by family, twin and adoption studies (Tormoehlen & Lessick, 2011, p. 486). Individuals afflicted with schizophrenia exhibit excess mortality, in comparison to the general population. All the same, several of the people with this disease will survive and suffer from it in their later life. This makes it clear that schizophrenia among the old will emerge as a major public health issue in the future. Consequently, treatment of schizophrenia that is based on evidence will become a major issue, with regard to the older patients. All the same, the absence of adequate data to guide the selection of antipsychotics for those suffering from schizophrenia in their later life (Suzuki, et al., 2011, p. 961). There is an absence regarding the essential criteria necessary for arriving at a diagnosis of schizophrenia. However, there is consensus regarding the general clinical aspects of this syndrome (Tandon, Nasrallah, & Keshavan, 2009, p. 3). Clinical Features of Schizophrenia Patients diagnosed with schizophrenia have a higher mortality rate, in comparison to the normal population. Even though these heightened mortality rates seem to be on an increas ing trend, many of the patients afflicted with schizophrenia survive until old age and continue to suffer from the disorder. Hence, geriatric schizophrenia needs to be addressed in the near future, as one can expect the number of patients affected by it to increase substantially (Suzuki, et al., 2011, p. 662). Patients affected with an early onset of schizophrenia and who do not show adequate
