The white sharks are very large, uncommon warm-blooded marine predators. The maturity for females is about 12 to 17 years while for males is about 8 to 10 years. The maximum length can be up to 6.5 meters. The white sharks reproduce only once in every 1 to 3 years and give birth to 2 to 10 pups per litter. The female white sharks develop embryos through oophagy whereby at the time of gestation, embryos feed on the eggs that are not fertilized that the female continues to ovulate during the first periods of pregnancy. The litter sizes have an estimate of two to seventeen while the maximum number of approximate term pumps confirmed by dissection of expecting females is ten. At the time of birth, the white shark measures around 120 to 150 centimeters and weighs up to 32 kilos.

Mahbubur Rahaman3 Department of Mechanical Engineering, Khulna University of Engineering Technology, Khulna 9203, Bangladesh Corresponding author: Md. Sourove Akther Momin (sur.sor269@gmail.com) Abstract: SPC (statistical process control) is an important tool to solve the manufacturing problem and the most modernized effective scheme to obtain process durability and fostering the process pertinence decreasing the variability. In manufacturing system, products do not run up against the proper province of quality permanently with the customer desire. This impermanency appears due to various productions of variations like machines, operators, materials, etc. The main purpose of control chart is to monitor the changes, and subsequently governing the scheme. The study deals with controlling and upliftment of the quality of pipe through checking and observing the pipe’s height, diameter and weight from pipe industry. From the investigation, X-bar chart, S and R control chart are developed for the variables. Furthermore, EWMA (exponentially weighted moving average) is used to focus for identifying the smal l process shifts All of the investigation represent, the process is in control or not.

Finding Myself in Horseback Riding Essay Example For Students

Finding Myself in Horseback Riding Essay I have thought long and hard for several days on what I could write about that would make me stand out or appear interesting. Ive never had a truly heartbreaking or painful experience and I consider myself to be an ordinary person. Im a decent athlete, maintain a B- average, fight with my siblings, go to church and do the basic day to day things. The only activity that comes to mind regarding how my character was molded is horses. Horses lend us wings we lack, when I enter the arena before a competition the only thing Im focused on is the beating heart of the horse underneath me. Our hearts beat together twice as fast. I cant describe the feeling I get after the gate shuts behind us and the event starts. The feeling is intoxicating. It doesnt matter where or when Im on my horse the feeling is always the same, I feel exhilarated and free. Being involved with horses has taught me to be independent, strong willed, and patient. My mom did an awesome job of playing the role as mom and dad. My mom has always told me that when I was younger I had an infectious smile, you never once saw me without a smile plastered on my face. That all changed December 2004, my dad walked out on our family leaving us broken. I was seven years old and after my dad left that happy-go-lucky kid lost her infectious smile, in fact that smile became a rarity. When I was nine my mom decided to introduce me to the therapeutic art of horseback riding. When being around horses every pain every worry goes away, anything that stresses me out becomes irrelevant, nothing else matter in the world except the horse and our connection. I have tried almost every type of horseback riding there is: english, western, bareback, pleasure riding, trail riding and jumping. Freshmen year I decided to try out local gymkhana shows to figure out if it was something I was into and I fell head over heels in love with every aspect of it. Last year, I joined California Gymkhana Association in District 33. I have finally found what Im good at and what I really love to do. Gymkhana is an equestrian event consisting of speed pattern races. Theres 13 events, the faster the rider completes the pattern the higher up on the leaderboard they will stand all year long you accumulate points to qualify for state championship, which I had the honor of attending this past summer with my family. The thirteen events are; poles I, poles II, barrels, figure 8 stake, figure 8 flags, keyhole, speed ball, birangle, quadrangle, hurry scurry, single stake, speed barrels, and big T. I was state ranked this past year in birangle, big t, speed barrels,and hurry scurry. My personal favorites is poles. My biggest strength when riding is my confidence and ability to read my horse. I always know what he is feeling by the way he moves and the way he looks at me. My biggest weakness last year was I look at the ground and not where I am going, I think I do this not because Im petrified of falling and getting hurt but because Im fearful of falling and humiliating myself. My mom makes a lot of sacrifices for me to compete and when I mess up or make mistakes I feel like Im disappointing her. After my state championship experience I have overcome this bad habit. I have learned you define your own success, and to me success is liking yourself, liking what you do and liking how you do it. I know I always try my best but not everyday turns out how you expect it so you have to learn to deal with what you get. Riding horses has taught me that nothing comes easy and you have to be patient. Horses are frustrating animals, they have minds of their own, there is no routine everything is different, there is always something new, and you cant give up. Theres three options in life give up, give in, or give it your all, you get to decide. .u168102690124a3401e4bf6a8ae3c0123 , .u168102690124a3401e4bf6a8ae3c0123 .postImageUrl , .u168102690124a3401e4bf6a8ae3c0123 .centered-text-area { min-height: 80px; position: relative; } .u168102690124a3401e4bf6a8ae3c0123 , .u168102690124a3401e4bf6a8ae3c0123:hover , .u168102690124a3401e4bf6a8ae3c0123:visited , .u168102690124a3401e4bf6a8ae3c0123:active { border:0!important; } .u168102690124a3401e4bf6a8ae3c0123 .clearfix:after { content: ""; display: table; clear: both; } .u168102690124a3401e4bf6a8ae3c0123 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u168102690124a3401e4bf6a8ae3c0123:active , .u168102690124a3401e4bf6a8ae3c0123:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u168102690124a3401e4bf6a8ae3c0123 .centered-text-area { width: 100%; position: relative ; } .u168102690124a3401e4bf6a8ae3c0123 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u168102690124a3401e4bf6a8ae3c0123 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u168102690124a3401e4bf6a8ae3c0123 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u168102690124a3401e4bf6a8ae3c0123:hover .ctaButton { background-color: #34495E!important; } .u168102690124a3401e4bf6a8ae3c0123 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u168102690124a3401e4bf6a8ae3c0123 .u168102690124a3401e4bf6a8ae3c0123-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u168102690124a3401e4bf6a8ae3c0123:after { content: ""; display: block; clear: both; } READ: Private Pension Plan EssayRiding with people in my district has influenced me in so many ways.

Was The 5th Century BCE A Golden Age For Athens Essays

Was the 5th Century BCE a Golden Age for Athens? subject = History 209 (Ancient Greek History) title = Was the 5th Century BCE a "Golden Age" for Athens? The 5th century BCE was a period of great development in Ancient Greece, and specifically in Athens. The development of so many cultural achievements within Athens and the Athenian Empire has led scholars to deem this period a "Golden Age." It is true that his period had many achievements, but in the light of the Athenians treatment of women, metics (non-Athenians living in Athens), and slaves it is given to question whether or not the period can truly be called "Golden." The 5th century and the Athenian Empire gave birth to an amazing amount of accomplishments. One such accomplishment was the minting of standard Athenian coins that were used throughout the Athenian holdings as valid for trade. The use of standard Athenian-minted coins helped the Athenians establish and maintain control over their empire by helping to control trade and the economy of the area to the Athenians' benefit. Since Athens regularly received tribute from the states it controlled, Pericles, the leader of Athens, began a building project in Athens that was legendary. Athens had been sacked by the Persians during the Persian Wars and Pericles set out to rebuild the city. The city's walls had already been rebuilt right after the end of the second Persian War so Pericles rebuilt temples, public grounds, and other impressive structures. One of the most famous structures to result from Pericles' building project was the Parthenon. The Parthenon and other such structures re-established Athens's glory and while some Athenians criticized the projects as too lavish, most Athenians enjoyed the benefits of the program. A major benefit to the Athenian people was that there was an abundance of work in the polis. The 5th century BCE was also an important time for Athenian thought. "Sophists," paid teachers, taught rhetoric amongst other subjects to wealthy Athenian citizens. The Sophists were criticized by Athenians who thought that Sophists were destroying Greek tradition by emphasizing rationalism over a belief in superstition, however it was this rationalism that became so important to Greek philosophers such as Socrates and Plato, both who belonged to the 5th century BCE. The Sophists high regard for rhetoric was later of great use to citizen addressing the Assembly in the developing Athenian democracy. Athenian democracy is perhaps considered the crowning achievement of the 5th century BCE. Democracy grew out of the status that poorer Athenians were gaining as rowers for the ships of the large Athenian fleet. Since these poorer Athenians now played a large part in the Athenian military, they ga8ined more say in the Athenian government. This led to a democratic government where "every male citizen over 18 years was eligible to attend and vote in the Assembly, which made all the important decisions of Athens in the 5th century BC?" (Demand 223). This democratic government is considered by some scholars to show the full enlightenment of the Athenians in the 5th century BCE. This glorious enlightenment seems somehow less enlightening, however, when one views this period from other than a male Athenian's eyes. Athenian enlightenment and democracy was by and for male citizens. The underprivileged of Athens included women, metics and slaves. The position of Athenian wives in Athenian society is clearly stated by Xenephon in his Oeconomicus. Ischomacus, a young husband, is conversing with Socrates about the duties of husband and wife. Ischomacus relates how he explained to his wife that the duties needed to support a household consisted of "indoor" and "outdoor" activities. He then explains to his wife, "And since labor and diligence are required both indoors and outdoors?it seems to me that the god prepared the woman's nature especially for indoor jobs and cares and the man's nature for outdoor jobs and concerns." (Spyridakis 206). This is the general attitude that Athenians held toward their wives. The Athenian wife was expected to marry and bring a dowry into her husband's house. Although this dowry was attached to the woman, she was in no way allowed to control the lands and moneys she might bring to her husband.. Similarly, women were not allowed to vote or take any part in the Assembly, being seen as unfit for this privilege. The primary function of a citizen's wife was to take care of domestic affairs and provide the citizen with an heir. Athenian wives were rarely seen outside of their houses, for respectable wives had at least one slave who would purchase needed items at market. Poorer

ESSAY WRITING STEP BY STEP Essays - Writing, Education,

ESSAY WRITING STEP BY STEP "Write an essay? But I don't know how!" If you are unnerved by the thought of writing a college essay, remember that this task can be accomplished in the same way as any other-one step at a time. An effective essay is the result of careful thinking, planning, writing, and revising. If you work hard on the first two steps, the last two will be much easier. Your goal is to produce an essay whose content is focused, well-developed, and clear. THINKING (Many decisions must be made before you actually write anything down.) 1. Consider purpose: The general purpose of your essay will usually be determined by your instructor. To be sure you know the specific purpose of your particular essay, complete this sentence: "The purpose of my essay is to ...." Example: General Purpose: Describe in detail an important characteristic of a person you know well. Specific purpose: The purpose of my essay is to describe my mother's kindness toward her family, friends, and co-workers. 2. Consider audience: The identity of your audience will determine how much background information will be necessary and what terms need to be used or defined. For example, an essay written for nurses on care of the elderly will include less background and more technical information than an essay written for the general public on the same topic. Unless directed otherwise, you should write for an uninformed audience. Even if your instructor is your audience, you still need to write as if he or she has little familiarity with your topic because your instructor wants to know the depth of your understanding. 3. Consider tone: The tone of your writing reveals your attitude toward your subject. Definition essays are usually written in an objective tone, but a humorous tone may be appropriate for a personal narrative. 4. Select and narrow a topic: Your topic should have significance for the reader and should be specific enough for you to adequately discuss in the required number of words or pages. If research is necessary, you may find it easier to first gather material on your general topic and then narrow your topic. (These two steps may need to be repeated more than once as you work on your paper.) For example, if you need to write a five-page essay on the effects of air pollution, you would severely limit the scope of your paper. The following example shows how to narrow your topic until the focus is specific enough for a five-page paper: The effects of air pollution (most general) The effects of air pollution on children's health The effects of air pollution on respiratory diseases in urban children The effects of air pollution on the prevalence and severity of childhood asthma in urban areas (most specific) 5. Choose a writing strategy: To communicate ideas to readers, writers employ many types of strategies, such as description, narration, comparison/contrast, definition, classification, argument/persuasion, analysis, and evaluation. The strategy (or "method" or "mode") you choose for a particular assignment will be partly determined by the purpose of your assignment and the expectations of the instructor. Using primarily one strategy may be appropriate for one assignment, while using several strategies may strengthen the effectiveness of another essay. Copyright Tacoma Community College Writing Center. All rights reserved. PLANNING (Write down a plan to guide you when you write your first draft.) 1. Create a tentative thesis: Write out the main point you want to make about your topic in a complete sentence. This sentence is called a thesis; it should be a mini-summary of your whole essay. Everything else that you write will be related to this idea. If you are able to at this point, write out your possible sub-points in sentences, also. Sub- points are the ideas you present to support ("prove") your thesis. In an argument essay the sub-points would be the reasons for your claim. The sub-points of a compare/contrast essay would be the similarities and differences between two or more subjects. You might not use these sentences word-for-word in your essay, but by writing out your ideas in this way you ensure that your thinking about your topic is crystal clear, which will assist you in remaining focused on your topic. Note: If your thesis must be supported by research, you need to read widely and take notes by whatever method you prefer before writing your tentative thesis. Be sure to include all necessary citation information in your notes. 2. Write down supporting content in a loosely-organized way: In order to logically relate your own ideas or contents

Iodine essays

Iodine essays Iodine is an essential macromineral. Almost half the iodine is found in the thyroid gland which is located in the throat. Iodine is an important component of thyroid hormones, which control energy, metabolism in the body as well as the bodys temperature, reproduction, and growth. It is not found in the body so it is very important that you get about .15 mg. daily. Some foods such as vegetables, grains, table salt, dairy products, and especially seafood are the best sources of iodine. Breathing in sea air everyday will give you a sufficient amount of iodine to prevent a disease called goiter. There are two types of goiter: toxic and simple. Toxic goiter is caused by excess of thyroxin secretion. Symptoms may include rapid heart beat, tremor, increased sweating, increased appetite, weight loss, weakness, and fatigue. Other symptoms may include eye problems such as staring or protrusion. Goiter affects over 200 million people throughout the world. 96% is caused by iodine deficiency. Goiters are rare in the U.S. and other industrialized countries because iodine is now added to table salt. Iodine affects body functions too. Hair and nail growth are affected by iodine. The brain, skin, speech, teeth, energy production, metabolism, and physical thyroid gland. Deficiency symptoms include dry hair, goiter, intellectual disability, paused growth, irritability, nervousness, and obesity. If a pregnant woman takes iodine during pregnancy, the development of goiter will be decreased for both the mother and the child. Iodine is the most efficient treatment for children who have goiter. Iodine does have a down side to it, too. It is not toxic up to 2,000 mcg daily, but it may cause acne. Too much iodine is can link to thyroid cancer. Some people are sensitive to iodine and may break out in a rash if their iodi... 1015 Natural Sources of Iodine-Where does iodine come from? If you said seaweed and burnt sponges you're not totally wrong. Natural sources of iodine include seafoods, vegetables, and in much lesser degrees, cereal.

The impact of climate changes in the near future Essay

The impact of climate changes in the near future - Essay Example These policies include implementing and regulating the existing laws and coming up with new laws that preserve the environment for the future and will not cause further climate change (Moller, Fielder, Berthold, pp. 3, 2010). The temperature of the entire world has changed, and this has been attributed to greenhouse gas emissions, particularly the fossil fuel burning, which has led to an increase in global warming (Kernan, pp. vii, 2010). This global warming leads to a dramatic temperature change, which is forecast to change more so in the future. Numerous studies and researches have concluded that some areas will witness an increase in temperature, while others may experience a drop in temperature. The changes in precipitation rate will great impacts, which will harm the temperature in many regions even more so. Climate change brings dangerous consequences with it. There are numerous impacts on agriculture, forestry, fishers, and other environmental factor (Moller, Fielder, & Bertho ld, pp.3, 2010). An even more pressing concern is the impact on the ecological systems because of further climate changes. The paper attempts to explain the various impacts of climate change. However, first it describes the causes of this climate change briefly. A sharp focus is also important; therefore, analysis of a particular region will further enhance the extreme problem of climate change. Centuries had passed since the formation of the world when the globe did not witness any climate change. However, this was to change when humans discovered fossil fuels. The population on the world multiplied drastically. Industrial Revolution spurred off economic development, but with the opportunity cost of environmental damage. The environmental damage has resulted in the extreme climate change. The greenhouse effect is perhaps the largest factor in this climate change. In the words of Timoth Wirth, former US senator and Undersecretary of State for the Global Affairs, â€Å"The greenhous e effect is the most significant economic, political, environmental, and human problem facing the 21st century† (Hardy, 222, 2003). Other reasons also form part of this global climate change. However, the paper is more concerned with describing the details of the impact of climate change on nearly facet of life in the planet, Earth (Hardy, pp. ix, 2003). The Intergovernmental Panel on Climate Change has shed light on the reality of global warming. The Fourth Report summarized a finding, which stated that the mean temperature has shown an increase of 1 degree centigrade, in the northern part of the world. There have been large changes in the distribution of rainfall, resulting in more rain in winters and less in the summers. Melting of glaciers has induced the seal level to rise by almost 20 cm, which can have devastating impacts. Natural disasters such as droughts, floods, and cyclones have gotten increasingly common, because of rapid climate change. The above-mentioned impact s are mainly the most common ones; however, these are not the only ones (Kernan, pp. 1, 2010). In the recent decades, all sorts of doubts regarding the effect of greenhouse emissions on global climate have fallen off. Although the climate of the world has changed in six periods since the evolution of Earth, the climate change the world undergoes currently is widely â€Å"unnatural†, and backed largely because of human activities. Glacier melting in the Northern Alps,
