The Application Of Wind Environmental Sciences Essay

The Application Of Wind Environmental Sciences Essay Wind comes from the suns uneven heating onto the earth surfaces, as hot air raises cold air sinks; there is a change in pressure, from high to low. Hence the change in pressure generated the movement of the air, as such wind is produced. Wind can be identifying as air in motion. Application of wind came a long way back to the past; during ancient time, sea explorers use wind with the help of the sails to sail through the seven seas. As for agriculture, farmers built simple windmills to grind the grains and also to pump water from the flowing rivers. And as technology advances, companies and researchers are coming up with designs and solutions to harness wind as a source of power in a greater scale. The Growth of Wind Power As technologies increases within time, human beings tends to create new things to ease works in life. Hence technology took a great part in the growth of wind power. In the earlier days, wind power was first used as mechanical power; this mechanical power was generated through the help of wind mill. The four blades wind mill generates mechanical power which helps to basically do all sorts of task: pumping of water, grinding of grains or even sawing of woods. But things changed in the 19th century, where electrical generators are introduced; people tried to fit in electrical generator into the wind mills in order to harness electricity. But results were not that ideal and slowly this electricity harnessing wind mills are forgotten. Even though such technology did die down or went missing for a century or so, it came back with a larger version of the olden days wind mill, it is called the wind turbine. Wind turbines first started off from rural areas where there are hills and mountains, which are known as onshore wind turbines or wind farms. But slowly it emerged with the help of new technology into shallow waters; shallow waters are places near the seas or oceans where they are nearer to the shore and easy to access. Then again technology took wind turbines studies to another level, which is what all companies had an eye on: deep water wind turbines. The evolution of wind mills to wind turbines till the recent offshore wind power, the next section we will be looking at the new wind power. What is Wind Power? A single wind turbine consists of a tower acting as a base and a fan-like propeller attached to the top of the base; energy is harnessed through the wind and the propeller. A series of wind turbines made up to a wind farm, a one stop of electrical energy power station. Advantages of Wind Power in General. Firstly, there is an abundant of wind everywhere; anywhere there is a high velocity of wind could be the location of a wind turbine. Secondly, during the operation of wind turbines and wind farms there are no air or land pollutions reported. It reduces global carbon foot prints. Thirdly, wind turbines come in a range of sizes and designs to cater to different needs. Lastly, with the increment of wind farms the cost of electricity may decrease. Disadvantages of Wind Power in General. Firstly, even though wind is abundant; wind is more or less predictable through seasons. There are possibilities of unsteady wind flow which might lead to wind farms not being able to produce enough electricity or power as per its peak. Secondly, wind farms produce silent pollution. As wind farms are greatly known as the non-polluting energy, little that many knows that it still do it parts in pollution; not to the environment but to the surrounding people. Pollutions like noise and vibration produced by operating the turbines. Types of wind power In Chapter 1 section 1.2 The Growth of Wind Power, it states that wind power have been brunched out into three different groups, namely: Onshore, Shallow Water and Deep Water, which is also known as offshore. In the later chapters of this literature review, we will look at the different types of wind power in depth.

Mostly over at the sub-urban areas: agriculture, country-side and mountain or hill tops. It is located mostly in U.S.A. and a few are in the United Kingdom, China and Australia. And as of 2012, the worlds largest onshore wind farm in terms of Current Capacity is Alta Wind Energy Centre in the USA; with 1020 MW on the record. 2.2 Two Types of Onshore Wind Turbines For Onshore wind turbines it is commonly categorized under two groups, namely: Horizontal Axis Wind Turbine (HAWT) and Vertical Axis Wind Turbine (VAWT). As per what the name HAWT says, its blades are designed to be parallel to the ground where as for VAWT; its blades are designed perpendicularly to the ground. horizontal axis wind turbineVertical Axis Wind Turbine HAWT VAWT http://www.freewebs.com/snatalie/turbine-types.gif For Horizontal Axis Wind Turbines (HAWT), there are three different designs under its belt: Design(s): Designs brief: Up wind turbines This design usually comes with a tail-like rudder that controls the hub and the blades so as to make sure the turbine will counter the wind direction at all times, even when there is a change of direction of the wind. Down wind turbines This design is of such that the wind will come in contact with the tower before it reaches the blades. Shrouded wind turbines This design has an additional of a structure which resembles a funnel that will capture the maximum flow of the wind to the blades. As for Vertical Axis Wind Turbines (VAWT), there are two different designs, namely: Savonius wind turbine and Darrieus wind turbine. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj4_LqQwxaPibUKwOSRGj9yc4t1KL2efPMq_UxQIuG9M57Kjd5XaoCoTuxMYl0xwHvDhKoI2Rkr-s6Pf6oZkeozr8d5UBFkdCpJ7yR1HKpR39NJIhvR4_UUN5GOIc-148BoHFLW7aTrRE4/s320/savonius.jpg Fig. 2.3 Advantages and Disadvantages of Both Types Horizontal Axis Wind Turbine Advantages Disadvantages Self-start system Single direction wind intake Stand-alone design 2. Installation is tedious Able to harness high speed wind Relevant to electricity Vertical Axis Wind Turbine Advantages Disadvantages Wind intake from all direction Needs a mechanism to start Installation is easy, as lesser materials are use Require mooring in order to support the structure Design only caters to slow wind speeds 2.4 Issues and Problems Affects Avian During the late 1980s it has been reported that birds are found death or injured by the wind turbines. Birds in the United States namely the Golden Eagles and the Red-tailed Hawks were being killed by the wind turbines or by electrocution. As both types of avian spices are under the federals protection scheme, it draws wildlife and avian activists attentions. And slowly as the increase of wind farms being built in the different parts of the world, it started to harm the birds living around the farms. Birds being killed by collisions with the turbines; airplanes has their own flight zone, so does the birds, having a wind farms situated right in the flight zone will eventually cause more damages to the birds living in that area. As more wind turbines and electrical cables are built and planted, birds being electrocuted are common; as birds will tend to build the nest on the hub or on top of the tower, electrocutions are inevitable. Migration of bird spices; having foreign objects or obstacles in the birds daily life does increase the tendency of it shifting to somewhere else. But then again the problem lies with how many in total percentage of the birds managed to survive through migration. With issues surfaced, engineers and activists came up ways to resolve it; by reducing the turbines to be built in flight zones, clearing of birds nests and not to expose electrical cables. Noise Pollutions For wind turbines, there are two types of contribution to the noise pollution, namely: aerodynamic noise and mechanical noise. Aerodynamic noise is produced by the turbines blades, which creates sounds with rotating blades. Whereas for mechanical noise, it is produced by the fiction and the gears in the hubs. Some noises are inaudible and some are not which are produced by the wind turbines that is built in the sub-urban areas are harming the people that lives there. Drives Holiday-makers Away

Dental Hygienist †Reflection Paper Essay

Abstract The convoluted way in which having good oral hygiene and how much it can impact one’s body has never lost my interest. When researching, I have read it is most common to get oral cancer And/or Periodontal Disease when not taking care of one’s self.

It is such a neat feeling knowing you can wake up excited to do what you have dreamed about your whole life. Since being a first generation college student in my family, I had no one teach me about the simplicity of education. The one thing I know is that since high school, it is something about the medical field that interested me. I took Career Explorations and it really helped what field I wanted to go for when studying in the medical field, particularly Dental Hygiene. What really caught my eye was that you get to help people and teach them.  This is one of my best interests. One of the struggles for me was not enrolling into college straight out of high school. Over the years I have looked at it as having time in researching in which career best fits me. First, you begin to look online, on how to become a Dental Hygienist, take a look on what are the first things you must do. In Arizona, there are many Community Colleges and a University that offer prerequisites and the Dental Hygiene program such as Rio Salado, Phoenix College, Carrington College and Northern Arizona University. The lowest degree you can get in this degree is an Associate’s Degree and the highest in a Bachelors degree. Hygienists typically need an Associate’s Degree in Dental Hygiene. Bachelor’s degrees in dental hygiene are also available, but are less common. A Bachelor’s or Master’s degree is usually required for research, teaching, or clinical practice in public or school health programs. High school students interested in becoming dental hygienists should take courses in biology, chemistry, and mathematics. Some Dental Hygiene programs also require applicants to have completed at least 1 year of college. Specific entrance requirements vary by school. Most schools offer laboratory, clinical, and classroom instruction. Hygienists study anatomy, physiology, nutrition, radiography, and Period ontology, which is the study of gum disease. (BLS 2014) To become a Dental Hygienist, it takes a lot of skills to be one. The important skills to have in this job is being Detail oriented, speaking, active listening, critical thinking, judgment and decisions making, compassion, patience, multitasking skills, coordination and physical stamina. In modern world, there are so many people that couldn’t stand not going to the dentist ever again. They depend on them to keep up with the oral hygiene, clean their teeth and get X-rays. From Dental Assistants to Dental Hygienists and Dentists, they are always willing to help you. People in the dentist office always advise to you how important it is to keep up with regular cleanings at least twice a year, and brush and floss your teeth daily. If you do not take care of your teeth, it could lead to bad things like oral cancer and Periodontal Disease. The Dental Hygienists are the  ones to help you prevent these things from happening. If you ask any person in this field if they enjoy their job, I know most would say yes. There is nothing more than a better feeling wake up every day knowing you are going to help someone. Although this career takes a lot of skills and education, it is worth it in the end. Most hygienists are aware that there are ‘better’ jobs out th ere that make a good amount of money, (a lot more than theirs) they would not trade it for anything else. Of course this is why it is such a growing field. This really shows that they truly love what they do. If there are any traits or skills listed above that fits you then this may be your career of choice. Over the years since researching this field, I have learned so much from it. There is good pay, they are flexible with you if you have a family and want to work part time. I think this job is perfect for anyone honestly. This is such a dynamic job to have. There are some things you must research before going into this job. How long does it take for? you to become a Dental Hygienist, what is the pay and availability in your area, and what is the total cost of the program. Although these may be stressful things to think about, but is very important to look into these things before going into this career. (ONETOONLINE, 2014) The level degree to pursue my career of choice is Associates Degree. I plan to continue to attend Glendale Community College to achieve my prerequisites and once I’m done with those, I will be attending Phoenix College for the Hygiene program. I have heard that this is one of the best schools to attend if you are looking to get a basic and quick degree in your interest. The advantages of the program is interacting with people, learning in depth about oral hygiene, and learning how to operate the X-Ray machines. The disadvantages is not knowing if it will be a promising career, hearing from stories. Although, living in Arizona, it is a great career to get into. The average earning/wages $81,470 per year ($39.17 hourly). Where I see myself in 10 years is being very happy and content with life. I can see myself a wonderful job, being married and having a family. I see that I won’t be struggling with money and not living paycheck to paycheck. It’s never a good feelin g not knowing how come up with the money for an owed bill. I also see myself living in California. It is  pricey living there, but there is so much to do there. The Dentistry field is high in demand there, so that one positive thing to think about living there. (SALARIES-BY-THE-CITY.ORG, 2014) There are many things to think about before making this step, but it is also an exciting time in your life. You are doing this to better yourself. You are picking a career that best fits you and what YOU want to do. Not what someone else wants you to do? This is the reason why I am choosing this.

The concept of tracking is an essential skill to the Aboriginal trackers in Australia. Before the colonization of the white settlers, tracking was a traditional trade skill in the lives of the Aboriginal people needed to survive in the environment of Australia. Soon after, tracking became a significant role in Aboriginal history because it molded the relationship between the Aboriginals and the white settlers. In the movie adaptation of the novel Follow the Rabbit Proof Fence, the tracker illustrates how perceptions of trackers can transform by witnessing the struggle of the tracker living in both white society and aboriginal culture. Therefore, in both the movie and the novel, tracking demonstrates how it has impacted the history of†¦show more content†¦Typically, men were the hunters and scouted larger animals for food to feed other members of the tribe. However, women were also taught how to track to kill smaller animals. For example, Molly started practicing at a young age to prove women hunted smaller animals by killing the goanna in the movie Rabbit Proof Fence (Noyce). Molly fought to go home by using the tracking skills she learned to help her survive without being captured by Moodoo. Tracking was a personal tool to many of the native people because it was used to find the location of animals and water. So, tracking became a life skill that was natural to the Aboriginals. Despite tracking being used as a life skill to the Indigenous people, it became a valuable skill that benefited the white settlers in conquering Australia’s land. White people needed the native trackers because they had difficulty exploring the new environment they wanted to nab. Once new white settlers started embezzling extra land, the Aboriginal people’s homes were seized by the white people. The white people made the natives inferior by limiting their hunting and killing more natives unfairly: â€Å"Soon the white people would take [their] land from [them] and there would be no recourse for any injustices committed against his people† (13).
