Is Wind Power Really Green Essay Example | Topics and Well Written Essays - 1750 words

Is Wind Power Really Green - Essay Example Search for sustainable alternative sources of energy for development on a commercial scale has thrown up several options like the wind power, solar power, geothermal, tidal wave etc. and among these, wind power (and solar power) is coming to the forefront in view of its long history of development and scalability. However, there are distracters, mainly from the traditional fuel suppliers, who find fault with the environmental credentials of windmills. These misgivings are ill-founded and it is quite clear from its growing popularity and rapid technological strides of the industry, that wind power is a sustainable and commercially viable option, which has minimal adverse impact on the environment in comparison with nuclear or fossil fuel power. The current total global energy demand per year, put at 400 x 1015 British Thermal Units (400 quadrillion BTU or approximately 117.2 million GWh), of which 41%, 24% and 22% are the respective shares of oil, coal and natural gas; the share of hydropower and other non-conventional energy sources is just about 13% (US Department of Energy, as quoted by McLamb, 2010). According to the International Energy Agency (IEA), electricity production has risen by about 250% over a 30 year period and this growth has far outstripped the growth of production of coal and natural gas, and was facilitated by vast investments in nuclear power plants, especially in the 1970s and 1980s (World Energy Statistics Manual, IEA, 2005, p.46). IEA points out that during this period, the ‘share of oil decreased from 25 to 8% while the share of nuclear increased from 3 to 17%’ (ibid). Thus while the total energy demand has been rapidly rising and would continue to do so in the foreseeable future, dependence on nuclear power is also increasing. The reasons for increased dependence on nuclear power are not far to seek – firstly, a realization that fossil fuels are not an inexhaustible

Chemistry Essays Saline & Fluids in the Body

Chemistry Essays Saline & Fluids in the Body Saline and Fluids Using saline as an example, outline the importance of solutions in the body and what is the concentration of normal saline and how the concentration of saline is controlled in the body and what effects on the cells an increase in saline concentration would have. Our bodies are fifty tosixty percent water, which therefore makes water an essential fluid for ourbodies. The main transporting agent in our body is the cells, and solutions arenecessary to execute functions such as:   Ã‚  Ã‚  Ã‚  Ã‚  Chemical balance   Ã‚  Ã‚  Ã‚  Ã‚  Circulation of blood   Ã‚  Ã‚  Ã‚  Ã‚  Transporting nutrients to the cells   Ã‚  Ã‚  Ã‚  Ã‚  Elimination of waste   Ã‚  Ã‚  Ã‚  Ã‚  respiration The main component ofthe blood, perspiration, saliva, mucus, lymphatic fluids and digestive juicesis water. The function of water also ensures the lubrication of the joints,that the muscles, skin, and organs is moisturized. The temperature of the bodyis also aided by water. Two thirds of water is situatedwithin the cells intracellular, and one third of water is found in the sitesbetween the cells interstitial and in the blood plasma. The composition ofsolutes in the intracellular and extracellular water can vary. A highconcentration of potassium ions is found in the intracellular cells, and a highconcentration of sodium and chloride ion is found in the extracellular cells. It is precarious to thesurvival of the human body that the accurate balance of fluids and salts ismaintained and the right pH acid balance. If the body loses fluids and salts,then dehydration can occur, and this can cause the concentration of salts toalter causing electrolyte imbalance. One of the mostimportant solutions in the body is saline, which is a solution consisting ofsodium chloride and distilled water. Salt plays a perilous function in the accurateoperation of the human body, as well as all other forms of life. The averageperson contains about eight ounces of salt, which facilitates muscles to contract,digestion to occur, the floe of blood, wounds to repair and fluids to beproperly regulated. A litre of isotonic or normal (0.9%) saline contains 154mmol of NaCI, comparable to 9 g of salt or 3.6 g of sodium. The regulation of salineand water equilibrium in the body is an example of homeostasis. Homeostasis isthe preservation of balance, or constant conditions, in a biological organismby means of habitual mechanisms that neutralize influences tending towarddisequilibrium. The correct composition of extracellular fluids and watercontent in the body is maintained by the important role played by the kidneys. Osmolarityis the amount of particles dissolved in a certain volume of fluid. Theosmolarity of fluid can be altered by the volume of fluid or by the quantity ofsolute molecules. In the duration of a day, the kidneys will manage 180 litersof blood, and will produce 1.5 liters of urine. The volume of water excreted bythe kidney is regulated by the anti-diuretic hormone (ADH: also referred toas vasopressin; diuresis means water loss and is therefore referred to as awater loss hormone. If the concentration offluid in the body drops below normal, the osmoreceptors in the hypothalamuswill recognize the resulting increase in osmolarity. ADH will be released bythe hypothalamus, in response to the change in osmolarity. The amount of fluidvolume lost must be replaced by drinking additional fluid, thus ensuring thatosmolarity returns to equilibrium and recovering the fluid loss. If the concentration offluid in the body increases above normal, this will also modify the osmolarityof the circulating fluids. The decrease in osmolarity is regulated by thehypothalamus, which stops producing ADH. In the absence of ADH, the kidney permitsfluid loss from the body. The kidney consists of numerous nephrons in which itfilters solutions, and then selectively reabsorbs or secretes different plasmacomponents. The entire composition of the nutrient molecules and most of thewater will be reabsorbed, and returned to the bloodstream. The major extracellularsalt is NaCl. The levels of osmolarity of the circulating body fluids aredetermined by the sodium and the chloride content. The kidney establishes theconcentration of Na+ loss from the body (Cl or anadditional anion will proceed Na+, so if Na+ levels aremonitored anion levels counteract automatically). If there is inadequate Na+inside the body, this will be identified by the kidney, which commences acomplex series of events, established as the renin/angiotensin/aldosterone pathway.In response to a decreased concentration of Na+, the kidney dischargesrenin into the blood. Renin acts on a plasma protein, angiotensinogen changingit into angiotensin I Angiotensin I is asubstrate for a changing enzyme, found widely in the lungs, which changes itinto angiotensin II. Angiotensin II has remarkable biological activity, causingthe release of aldosterone acting on the adrenal cortex. Aldosterone is ahormone that operates on the kidney to inhibit Na+ loss from thebody. Inversely, should there be an excess of Na+ in the body, adecrease in renin discharge will lead to a deterioration in the aldosterone concentrationsand an increase in Na+ deficiency in the urine. Variation in the Na+concentration is a protracted process than that of circulating fluid levels andmay require hours to days for completion. The obstacle between theextra and intra cellular compartments is known as the cell membrane. Watercan occur liberally through biological membranes but many solutes cannot. Whenone section has a larger concentration of solutes, the direction of the flow ofwater is from the section with the depleted concentration to the section withthe larger concentration. This process is known as osmosis. Osmosis is the migrationof water from an area of high water concentration through a semi-permeablemembrane to a region of low water concentration. In a hypotonic solutionof saline, the concentration of the solute molecules outside the cells is lowerthan that the concentration of solutes inside the cell. This in turn willenable the water to diffuse into the cell, until equilibrium is established.This flow of water into the cell causes the cell to swell. References 1.

The Challenges Faced In Jane E :: essays research papers

The novel, Jane Eyre, by Charlotte Bronte, has a plot that is filled with an extraordinary amount of problems. Or so it seems as you are reading it. However, it comes to your attention after you have finished it, that there is a common thread running throughout the book. There are many little difficulties that the main character, the indomitable Jane Eyre, must deal with, but once you reach the end of the book you begin to realize that all of Jane's problems are based around one thing. Jane searches throughout the book for love and acceptance, and is forced to endure many hardships before finding them. First, she must cope with the betrayal of the people who are supposed to be her family - her aunt, Mrs. Reed, and her children, Eliza, Georgiana, and John. Then there is the issue of Jane's time at Lowood School, and how Jane goes out on her own after her best friend leaves. She takes a position at Thornfield Hall as a tutor, and makes some new friendships and even a romance. Yet her n ewfound happiness is taken away from her and she once again must start over. Then finally, after enduring so much, during the course of the book, Jane finally finds a true family and love, in rather unexpected places.   Ã‚  Ã‚  Ã‚  Ã‚  At the start of Jane Eyre, Jane is living with her widowed aunt, Mrs. Reed, and her family after being orphaned. Jane is bitterly unhappy there because she is constantly tormented by her cousins, John, Eliza, and Georgiana. After reading the entire book you realize that Jane was perfectly capable of dealing with that issue on her own, but what made it unbearable was that Mrs. Reed always sided with her children, and never admitted to herself that her offspring could ever do such things as they did to Jane. Therefore, Jane was always punished for what the other three children did, and was branded a liar by Mrs. Reed. This point in the book marks the beginning of Jane's primary conflict in the novel. She feels unloved and unaccepted by the world, as her own family betrays her.   Ã‚  Ã‚  Ã‚  Ã‚  This feeling intensifies when Mr. Brocklehurst arrives to take Jane away to Lowood School. Her aunt is pleased to see her go, but manages to influence Jane's life even after Jane is settled in at the charity school, by informing Mr.

Cultural Sensitive Care Essay -- Sociology, Transcultural Care

Cultural sensitive care Culture The classic definition for culture was proposed by Tylor (1871/1958) and still commonly cited: Culture is â€Å"that complex whole which includes knowledge, belief, arts, morals, law, custom, and many other capabilities and habits acquired by man as a member of society† (p. 1). This definition focuses on attributes that are acquired through growing up or living in a particular society, rather than through biological inheritance (Kottak, 2002). In Giger and Davidhizar’s (1991) Model for transcultural care, culture was defined as a patterned behavioral response that develops over time as a result of imprinting the mind through social and religious structures and intellectual and artistic manifestations. Culture is also the result of acquired mechanisms that may have innate influences but are primarily affected by internal and external stimuli. This definition gives more illustration on the social and religious dimensions and identified that culture is shaped by values, be liefs, norms, and practices that are learned and transmitted by members of the same cultural group (Leininger, 1991). Leininger (1991) explained In her model of transcultural care that culture is focused on the total or holistic life ways of human beings, religion (spiritual), kinship, politico-legal, education, technology, language, environmental context, and worldview are all considered. The importance of understanding patients’ culture was clearly articulated in Giger and Davidhizar’s (1991) work. They have indicated that culture guides our thinking, doing, and being and becomes patterned expressions of who we are and that cultural values guide actions and decision-making and facilitate self-worth and self-esteem. Transcul... ...ials of Baccalaureate Education for Professional Nursing Practice (1998) and The Essentials of Master’s Education for Advanced Practice Nursing (1995). Other disciplines have adopted similar steps to ensure appropriate level of knowledge and skills on cultural diversity. Elementary school and college educators were urged to respect the cultural richness of students and incorporate culturally sensitive curricula (Percival & Black, 2000). The importance of adequate physician knowledge in relation to cultural sensitivity has led to the imposition of legal mandates (Institute for International Research, 2005). In the military field, it has been recommended that cultural sensitivity training be added to the basic training curriculum (Holt, 2002). Additionally, in the market of business, cultural training is linked as the key to success (Local Relationships, 2003).

International Business Entry Case Study Essay

High turnover. Small companies tend to have a small structure, then job opportunities are few, which force employees to change job. Poor customer service. Distributors mostly only care about selling off a product, then they direct customers with Microsoft. The main problem is that Microsoft Customer service is focused on developed countries, where the needs and tools are greatly different. In some cases the technical service is non-existent, heavily hurting the image of the company, not the distributor. Poor input for further developing products. If all the deployment and input is being done and received by a distributor, then it is most likely that the information will never reach Microsoft’s engineering department. Without that knowledge products will stall for that particular market in a short period of time, inflicting loses in the long run for the company. 2. Are there countries where Microsoft’s strategy might not work? Why? Small countries with an unique language possibly are the toughest. Microsoft strategy mean that while local partners are relied to market the products, Microsoft is still in charge of the code and language. In that regard Microsoft is very vulnerable to small IT companies that develop solutions for their language. With small partners, it is easy for local developers to attract those distribution channels for their own product, therefore using Microsoft’s resources and know-how to make profit out of other products, making Microsoft lose money. 3. What other kinds of businesses might find Microsoft’s strategy to be effective? Please explain. Car manufacturers. They basically operate the same scheme with distributors. When a car’s manufacturer enter a new country most times they give the concession to sell the cars to a local person or company. Almost entirely those distributors operate in a very small area. The manufacturer covers Marketing and promotion, while the distributor has to develop their sales only in their area. 4. How might Microsoft need to change its strategy once it has established a strong position in a foreign market? They need to deploy a strong services net. They need to be in constant contact with customers in order to assure that they meet their current and future needs. They need to deploy training facilities for their products in order to have a strong pool of expertise from where enterprises can nurture in order to keep fidelity with the products. They need to partner with high profile local companies to develop solutions in order to gain traction in the country. 5. Describe how host governments might react to Microsoft’s entry strategy? Governments usually react in a good way. The way Microsoft do business benefit host countries a lot, since it creates a lot of jobs for the locals. Nonetheless there might be some countries who could think that Microsoft is a danger for their local IT industry. In those cases their strategy also soften their position a lot, since the entry in indirect. Reference Glusing, J. (2006, June 1).
