The, The Whiteness Of The Whale - 1818 Words

Throughout his novel, Moby Dick, Herman Melville will often devote entire chapters to the thoughts and actions of specific characters. Two specific examples of this type of chapter are Chapter 36, The Quarter-Deck, and Chapter 42, The Whiteness of the Whale. The first of these chapters depicts Ahab addressing his crew for the first time in order to convince them to hunt down Moby Dick. The second offers insight to the fear that is brought upon by the mere mention of Moby Dick The significance and effectiveness of each of these chapters are enhanced by Melville’s use of rhetoric and style respectively. In Chapter 36, Ahab finally chooses to reveal the true purpose of this whaling voyage: To hunt down and kill Moby Dick. He does so through a grandiose speech in which he rallies almost the entire crew to his cause through a number of persuasive techniques. Ahab begins his speech by asking the crew a few basic questions about whaling. These questions lay out the basic purpose of this voyage: To hunt whales. In doing so, Ahab is laying the groundwork to convince the crew to hunt down a very specific whale: Moby Dick. In addition, the call-and-response used in this portion of the speech unifies and excites the crew, thereby making them more open to what Ahab is about to say. Immediately following this, Ahab reveals his desire to kill the White Whale and offers an ounce of gold to the first man to spot it. This use of bribery piques the interest of the crew and offers anShow MoreRelatedEssay about The Whiteness of the Whale878 Words   |  4 PagesThe Great White Whale and its Many Meanings Herman Melville, in his epic novel Moby-Dick, utilizes the symbolism of the color of the Great White Whale to demonstrate his theme of duality.

Spf and Sunscreen Free Essays

What do the SPF Numbers on Sunscreen mean? What is the SPF number on the sun screens? The higher the number, the better, right? Before you head out in the sun this summer, you should know a few things about SPF. What is it, exactly? What do the numbers mean, and how high can they go? We use sunscreen to block ultraviolet light from damaging the skin. There are two categories of UV light. We will write a custom essay sample on Spf and Sunscreen or any similar topic only for you Order Now The UVA- has more long-term damaging effects on the skin, like premature aging. UVB –causes sunburns. SPF or sun protection factor, numbers were introduced in 1962 to measure a sunscreen’s effect against UVB rays. To determine a sunscreen’s SPF, testers round up 20 sun-sensitive people and measure the amount of UV rays it takes them to burn without sunscreen. Then they redo the test with sunscreen. The â€Å"with sunscreen† number is divided by the â€Å"without sunscreen† number, and the result is rounded down to the nearest five. This is the SPF. SPF numbers start at 2 and have just recently reached 70. To figure out how long you can stay in the sun with a given SPF, use this equation: Minutes to burn without sunscreen x SPF number = maximum sun exposure time For example, if you burn after 10 minutes of sun exposure, an SPF of 15 will allow you to be in the sun for up to 150 minutes without burning. You should know that this equation is not always accurate. People usually use far less sunscreen than the amount used in testing. In the real world, the average sun worshipper uses half the amount of sunscreen used in the laboratory, which could result in a sunburn in half the time. My mom and her family grew up around a swimming pool. They spend all day by the pool when we go out of town. My grandparents have to get cancer removed every year. It is true, a higher SPF number means more sun-exposure time. It also indicates the level of UVB absorption, but this number doesn’t increase exponentially, which can be confusing. For example, an SPF of 15 absorbs 93. 3 percent of UVB rays, but an SPF of 30 absorbs 96. 7 percent. The SPF number has doubled, but the absorption rate has increased by only 3. 4 percent. Because of the confusion about UVB absorption, the FDA proposed a cap on SPF numbers. Any sunscreen higher than 30 SPF would be a â€Å"30-plus. Thirty was the decided cap because above that, the percentage of UVB absorbed and overall protection of the skin increases only slightly, but people may misinterpret these higher SPF numbers as a much higher level of protection or even a guarantee of all-day protection. SPF| % UV absorbed | 2| 50 | 4 | 70 | 8 | 87. 5 | 15 | 93. 3 | 30 | 96. 7 | 50 | 98 | As helpf ul as the FDA was trying to be, the cap is clearly not in practice: Neutrogena and Hawaiian Tropic recently released sunscreens boasting an SPF of 70. We have sunscreens ranging from 15 SPF to 70 SPF in our cupboard at home. There are several factors that allow all of us to get a sunburn even if we have sunscreen on. First, we don’t use enough. Second, despite waterproof or sweatproof labels, all sunscreens decrease in effectiveness when exposed to water or sweat. If you don’t apply the correct amount and then reapply after exposure to water, a 12-hour bake in the sun could give you a serious sunburn. The bottom line is that a sunscreen with a higher SPF does offer higher protection against UVB rays, but once you get past SPF 30, protection doesn’t increase very much, and the higher number may give you a false sense of protection. Instead of letting SPF be your only guide to sun protection, avoid a burn by following a few simple sunscreen rules. 1. Know yourself: If you are whiter than a sheet of paper, if your Aunt Linda has skin cancer, or if you are sensitive to the sun because of a medication or a medical condition, take extra measures. Stay out of the sun as much as possible, wear a hat when you are out, use a broad-spectrum sunscreen with a high SPF and reapply that sunscreen often. Don’t put a lot of sun screen on and lay out by the pool. 2. Look for â€Å"Broad-spectrum† label: The SPF number indicates protection only against UVB rays — many sunscreens, even those with a high SPF, allow UVA rays to be absorbed by the skin. UVA protection is usually indicated by a â€Å"broad-spectrum† label. Look for this label to ensure the most well-rounded sun coverage. Broad-spectrum sunscreen ensures protection from both UVA and UVB rays. The latest sunscreens boast new chemicals, like Mexoryl, which has proven to be one of the most effective UVA-blockers out there. 3. Be prepared- be proactive in planning: To be effective, sunscreen eeds to be fully absorbed into the skin, so apply it 15 to 30 minutes before you even step into the sun. Make sure your whole family has taken the time to put sunscreen on. Then get ready for your time outdoors. 4. Reapply yourself: Whether you’re lying by the pool or mowing the lawn, you’ll probably be exposed to sweat or water, the natural enemies of sunscreen. To b e safe, reapply after you swim or sweat. If you are going to a friends home or to the park, take a bottle with you. My mom keeps a bottle in each of our golf bags. It takes almost 3 hours to play 9 holes in the junior league and it is extremely hot. 5. Full exposure: No matter how high the SPF, sunscreen can protect only the skin it covers. The most commonly missed spots are the temples, ears, back of the neck and top of the feet. If you are sometimes guilty of losing your focus while applying your lotion, try one of the sunscreens that contains disappearing colorants, so you can identify unlotioned areas before they burn to a crisp. Our generation needs to learn from our parents and grandparents. My grandma and grandpa Cox are always having skin cancer frozen or burned. My grandma has had a small part of her nose removed from malignant skin cancer. My mom grew up with a pool in her backyard her whole life. She spent so many years laying out in the sun with no sunscreen on. She also spent a year at BYU Hawaii so she could be in the sun. Our family is good about putting sunscreen on but we can all be better. I have learned so much about protecting my skin. This summer I am going to make a goal to wear sunscreen at the beginning of the day and have a bottle with me. How to cite Spf and Sunscreen, Essay examples

Population and Water Resources free essay sample

Abstract Water is a finite resource which means that the total amount of water in the planet is only limited. Its supply remains the same and yet human population recently grows resulting to a decrease of available amount of freshwater per person. The relatively small amount of available freshwater elaborates on how critical it is for everyone to help preserve and maintain clean, healthy lakes and streams, our sources of water. Water is mostly now being wasted because it is under-priced. We do not realize the significance of it. Also, the uneven distribution of water resources has led to the stage of scarcity in a number of regions. The paper aims to find possible ways on how to stop mans actions of wasting and teetering on the planets supply of water. Water is lifes matter and matrix, mother and medium. There is no life without water. -Albert Szent-Gyorgyi For survival, man depends on water. We will write a custom essay sample on Population and Water Resources or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page It circulates and goes through our bodies, replenishing nutrients and carrying away waste materials. Water came from the ice-capped mountains, melted and eventually became rivers and to oceans. It is the most distributed substance on our planet, and in different amounts it is available everywhere and plays a major role in human life. Of most importance is fresh water. No activities of human being and life is impossible without it because it can be substituted by nothing. In different histories, water has been a facet of ritual. Civilizations have emerged in different countries. The Chinese civilization originated in the Yellow River (Huang Ho) and the Egyptian from the Nile River. Both rivers have the ability to produce fertile soil, which made it easy for cities to spring up alongside the banks. The Earth’s supply of water remains the same and yet the world population continues to grow. Apart from the population increase and the low rainfall in many densely populated areas, demand for water has risen for other reasons. In the world today, progress and prosperity go hand in hand with a reliable water supply. Fresh water is renewable only by rainfall, at the rate of 40,000 to 50,000 cubic kilometers per year. But due to the intensive urbanization, deforestation, and industrial farming, the earths surface is drying. If present trends still persist, the water in all river basins on every continent could steadily be depleted. Contamination by pollutants has seriously degraded water quality in many rivers, lakes and groundwater resources reducing the supply of water for human use. While the increase in population alone has increased the challenges to water management, particularly in the area of sanitation, the greatest threats are from a wide variety of industrial and agricultural sources. Drinking and tap water are often wasted because they are under-priced. The cost of using or mis-using water is paid either by commonly the user or at large by the community. As water demand continues to increase, it becomes even more important to see that it is directed to high-valued social uses. As the population increases, the amount of freshwater available per person decreases. Man has been moving unsteadily on the edge of a global crisis that is being worsen by climate change, which are shrinking glaciers and raising sea levels. Between 1900 and 1995, world demand for water multiplied by six, twice the rate of population growth over the same period. The six billion people use nearly 30% of the world’s total accessible renewal supply of water. By 2025, that value may reach 70% and yet billions of people lack basic water services, and millions die each year from water-related diseases. According to the United Nations, more than one billion people living on earth already lack access to fresh drinking water. Just as our bodies require water to dispose of waste products, abundant water is required for proper sanitation. Food production would also be dependent on water. Many crops, of course, are watered by rain, but in recent times irrigation has become the key to feeding the worlds rapidly growing population. Today 36 percent of the worlds harvest depends on irrigation. But the worlds total area of irrigated cropland reached a peak about 20 years ago, and it has been falling steadily since then. If a large amount of water flows out in our home and if we have a hygienic toilet that conveniently flushes away waste, it may be hard to believe that the world is running out of an adequate supply of water. Only 20 percent of mankind enjoy such luxuries. In Africa, many women spend as much as six hours a day fetching water and frequently it is polluted.

Applying to Go to Graduate School for a Different Major

Applying to Go to Graduate School for a Different Major Many students find that their career would benefit from additional studies that differ from their bachelors degrees. They may learn that their interests lie in a different field than their major or that their current field has grown and new avenues for study have emerged since their earlier years in academia. Demonstrate Your Capabilities While your graduate options are not limited by your college major, you still, however, have to work hard to demonstrate that youre a good candidate for graduate programs in your newly chosen field. Admittance to graduate school is all about how well you match the program. If you can demonstrate that you have the experiences and competencies to succeed, that may help your chances of getting accepted. Focus on the skills and life experiences that led you to switch your studies. Seek Related Experience Most graduate programs in biology will not accept a student without undergraduate science coursework. This is true of most areas of graduate study. To demonstrate competence you might consider engaging in internships or additional coursework. If, for example, your bachelors degree is in psychology and you wish to apply to a masters program in biology, take some science courses can demonstrate that you have a solid science background. Check your local community college or look into online courses. Take the Subject GRE If youre switching fields of study, its in your best interest to take the Subject GRE, even though its likely not required. A solid score on this exam illustrates your mastery of the subject matter, which can show your ability to succeed in the new field. Get Certified While a certificate is not the same as a graduate degree, many programs are rigorous and can be a great precursor to your next degree. Certifications are often affordable and can be done in a short period of time, and they can prove your mastery of the material. Some certificate programs offer courses similar to those youd find in graduate school and can prepare you for the rigorous studies ahead. Use Your Admissions Essay to Demonstrate Your Fit Your graduate school admissions essay is your opportunity to speak to the graduate committee. Use this essay to show how your education and experiences specifically align with the graduate program.  Some fields, like law, relate to many courses of study. Discuss your interest in the field and how your experiences have prepared you to succeed in the field. Draw attention to courses youve taken or experiences that illustrate your interest or competence in the area to which you aspire. For example, as a psychology major who wishes to study biology, emphasize the aspects of your education that overlap with biology, such as the emphasis on understanding the brain as an influence on behavior, as well courses in methodology and statistics, and your research experience. Explain why youre making a transition from one field to another, why you have the background to do so, why youll be a good graduate student, as well as your career goals. Ultimately graduate school admissions committees want to see evidence of your interest, knowledge, and competence. They want to know if you have the ability to fulfill degree requirements and if youre a good risk.  Keep the admissions committees perspective in mind, and youll have an advantage in the admissions process despite having the wrong undergraduate major.

Types of Prop Shaft Seals, Old and Modern

Types of Prop Shaft Seals, Old and Modern Modern vessels use a combination of technologies for sealing prop shafts to achieve higher performance with less maintenance. Fiber and Lubricant These are just like the old days but with better products. Plant fibers are replaced with synthetics in these systems and lubricants are designed to remain in a solid state rather than liquefy when heated by friction. This type of product can be used in any regular stuffing box. In the past few years real hemp has become available again, so next time you clean out that stuffing box, get some hemp fiber and mix up some beeswax and linseed oil and you will have better performance than the modern stuffing box repacking kits will give you. Synthetic Putty This is a clay type of product which resembles modeling clay. It acts as an extra layer of defense in a regular stuffing box. Clay seals still require a proper lubricant on the shaft and reinforcement with square braid fiber. This is a lower maintenance solution but still requires regular service. The return of real hemp to the United States market means that stuffing box materials wont break down or melt, which is what clay and putty protect against. Loose hemp fiber is soaked with warm beeswax and linseed oil and that is held in place with a woven hemp grommet like those shown in Ashleys Book of Knots. Mechanical Pack-Less Seals This is a product used on many vessels in a variety of conditions. The unit consists of a high-tolerance, low friction bushing in a stainless steel retainer. PYI is the most well-known manufacturer for retrofit and new build applications. It requires almost no maintenance and is watertight. If you consider vessel downtime and the labor of a traditional stuffing box, the extra cost is worthwhile. The pack-less seals also have the advantage of retaining the prop shaft itself, in case it separates from the drive unit. Losing a shaft will result in a vigorous jet of water entering your bilge compartment. One minor issue is the need for a positive pressure line to feed the surface of the graphite bushing and prevent wear. Some manufacturers do this more elegantly than others and include the positive pressure source in the shaft log housing. Some still have a need for a separate thru-hull fitting which just adds complexity. Including a pre-tapped port for a pressure sensor would be nice, so that pressure around the bushing could be monitored automatically, although this can easily be fitted to the positive pressure line if one exists on your model. Weve encountered a few of these packless units when they were run dry; it shows just how fast they can wear the replaceable components. The cost is far less than it would be for a new complete unit but it still requires a shaft-out repair, which means alignment and tuning for each individual component from the engine to the prop. Dry runs on old style packing are fixed with a partial turn of a man-sized wrench and cost little more than a pair of disposable gloves and some hand cleaner. With practice, the synthetic putty can give you a bilge that is nearly as dry as one fitted with packless logs. Check with your insurance provider, you may receive a discount by changing to a pack-less seal. You will certainly make the crew member who acts as your Oilier happy.

Red Sorghum by Zhang Yimou Essay Example | Topics and Well Written Essays - 1250 words

Red Sorghum by Zhang Yimou - Essay Example 2. The cultural significance of femininity in China is highlighted in the article. The idea of the feminine becomes one that is in controversy because of the several clashing belief systems of the film. The Confucian ethics and Buddhist traditions first define the feminine of China in one specific way. This is combined with the class structure that is a part of the feminine, which is defined by the expectations of Chinese culture. The Chinese culture is defined first by the history and memory that defines the feminine into the yin and yang roles. The mythical elements are defined by this as well, which creates different feminine roles that are within the culture. After the traditional roles are defined, the movie moves into ideas of the feminine through the different belief systems in the culture. The movie specifically defines the idea of yin and yang as a part of the cosmic order, which is a part of the traditional roles and the feminine.
