The Hellenic Period Essays - Ancient Greek Philosophers, Parmenides
The Hellenic Period During the Greek Golden Age, workmanship and theory communicated hellenic weltanschauung, their interesting attitude toward the world and lifestyle. Through crafted by specialists, writers, and rationalists, one can see the two sides of the tangled frameworks of the world, for example, great versus fiendish, request versus disarray, solidness versus transition, relativism versus absolutism and equalization and concordance. The Greeks were realists. They received the philosophical convention which says that physical issue is the main reality known to man; everything else, including thought, feeling, mind and will can be clarified as far as physical laws. Their realism was communicated in an unnecessary respect for common, wonderful material things and concerns. They utilized their craft to show the wonders of humankind and man. The stone workers of the Golden Age planned to make elegant, solid and completely shaped figures. Their specialty indicated normal positions and insightful art iculations as opposed to extract fine arts. Their principles of request and equalization became norms for old style workmanship in western human progress. The Greeks were glad for their sanctuaries and other design, made to respect the divine beings and embellish the polis (city-state). Their celebrated building styles were the overwhelming Doric segments and the thin looked over Ionian segments. The Parthenon, the Greek sanctuary for the goddess Athena, is a perfect case of balance and extent. The sides of the Parthenon give an optical figment of ideal parity on all sides. Their longing for balance in workmanship and engineering speaks to the equalization of the world; request and control are communicated in the straightforwardness of lines and shapes. The subsequent by and large structure cooperates to accomplish congruity. In old Greece, open show was more than amusement. It was a type of government funded training. It managed issues of significance to the individuals, for exampl e, the authority of the pioneers, the intensity of the individuals, inquiries of equity, ethical quality, wars, harmony, the obligations of the divine beings, family life and city living. Aeschylus expounded on the rages and how they rebuffed man for bad behaviors. This shows he accepted that confusion would be rebuffed on the grounds that request (and law) is the perfect state. Sophocles is most popular for his plays of Oedipus. Those plays managed family and city dedication. The Greeks accentuated, especially in their plays, the significance of steadfastness as an objective to make progress toward. We gain proficiency with a ton about Greek perspectives through their way of thinking, which truly implies the adoration for information. The Greeks taught through a progression of inquiries and answers, so as to more readily instruct about existence and the universe. The principal scholar was Thales. He put stock in absolutism and unceasing issue. He said that water was the first issue and that without it, there would be no life. Parmenides expressed that steadiness and lastingness were the hidden states of the universe. He accepted that change is just a hallucination and that one's faculties can just handle shallow real factors of progress. Heroditus contended with Parmenides saying that change was the fundamental state of the real world. He further guaranteed that all perpetual quality was bogus. Subsequently he considered things to be normally being in motion instead of a steady state. Democritus contended with both Parmenides and Heroditus. He demanded that there is not all that much and that solitary issue existed. He at that point proceeded to state that everything is made of minimal undetectable particles, snared in various game plans. He was an atomist. The Greek rationalists proceeded to scrutinize the idea of being and the importance of life. Pythagoras was the main metaphysicist, one who concentrates past physical presence. He put stock in a partition among soul and body, a restriction among great and underhanded and among dissension and amicability. In the fifth century, the Greeks gained from Sophists, who accepted that the perspectives on society are guidelines and the sole estimation of good, truth, equity and excellence. Protagoras was a skeptic. He said that, man is the proportion of all things. He had confidence in a consistent motion, and that nothing is completely right or wrong, yet subject to change. His view is a lot of like that held by Parmenides. The rationalists at that point posed an inquiry, for example, what might occur if things that weren't right were seen by society as worthy? What, for

Common and Rare Risperdal Side Effects
Common and Rare Risperdal Side Effects Bipolar Disorder Treatment Medications Print Common and Rare Side Effects When Taking Risperdal What You Should Know Before Starting Treatment By Marcia Purse Marcia Purse is a mental health writer and bipolar disorder advocate who brings strong research skills and personal experiences to her writing. Learn about our editorial policy Marcia Purse Medically reviewed by Medically reviewed by Steven Gans, MD on March 01, 2015 Steven Gans, MD is board-certified in psychiatry and is an active supervisor, teacher, and mentor at Massachusetts General Hospital. Learn about our Medical Review Board Steven Gans, MD Updated on January 06, 2020 Tara Moore Collection/Taxi/Getty Images More in Bipolar Disorder Treatment Medications Symptoms Diagnosis Risperdal (risperidone) is an atypical antipsychotic drug often prescribed for the treatment of schizophrenia, psychotic episodes of bipolar disorder, and other mental illnesses. While Risperdal can be effective in treating these disorders, you should be aware of the potential side effects before starting treatment. While many of the side effects are manageable, others may be serious and, in rare cases, life-threatening. Common Side Effects Risperdal can cause side effects for a variety of reasons. Because the drug has antihistaminic properties (similar to older antihistamine drugs), it may have a sedating effect in some people. It also acts as an alpha-adrenergic blocker, meaning that it interferes with certain hormones that regulate blood flow and blood pressure. Risperdal also has anticholinergic effects that can alter how smooth muscles (those that make up the internal organs) function. Because of these properties, Risperdal may cause the following side effects in at least one percent of users: AgitationAmenorrhea (absent period)AnxietyArthralgia (joint pain)Asthenia (physical weakness and lack of energy)Blurred visionConstipationCoughDiarrheaEpistaxis (nosebleeds)DizzinessDyspnea (shortness of breath)Excessive salivationFatigueGalactorrhea (milky breast discharge)Gynecomastia (male breast enlargement)Hirsutism (abnormal hair growth in women)Increased appetiteIndigestionMyalgia (muscle pain)Nausea and vomitingNasal congestionPainful intercourse in womenRashRetrograde ejaculation (ejaculation of semen into the bladder rather than out of the body)Seborrhea (a scaly, patchy skin condition)Somnolence (sleepiness or drowsiness)Sore throatSleep disturbancesSuicidal thoughtsWeight gainUpper abdominal painUpper respiratory tract infectionUrinary incontinenceXerostomia (dry mouth) Extrapyramidal Side Effects Extrapyramidal side effects (EPS) are those that affect the central nervous system and cause movement problems. EPS can affect as many as one of every four people who take Risperdal, although most cases are relatively mild.?? Other than previous history of EPS, there is no way to know in advance whether youll experience extrapyramidal side effects or not. Types of EPS Tardive dyskinesia is among the most common EPS experienced by Risperdal users. It is characterized by involuntary and repetitive movements, including those of the face, mouth, tongue, arms, or legs. These may include lip-smacking, grimacing, making chewing motions, rocking, rotating the ankles or legs, marching in place, sticking out the tongue, or making repetitive sounds such as humming or grunting. Other types of EPS include: Akathisia (a feeling of inner restlessness and inability to stay still, often referred to as the rabbit syndrome)Akinesia (loss or impairment of voluntary movement)Dystonic reactions (intermittent and involuntary contractions of the muscles of the face, neck, trunk, pelvis, and extremities)Parkinsonism (a group of neurological disorders that cause movement problems similar to Parkinsons disease, including tremors, slow movement, and stiffness) Risk Factors The risk of EPS is largely dose-dependent. Similarly, the type of formulation you take can also influence your risk. By way of example: Oral formulations of Risperdal are associated with a two percent to 12 percent risk of tremors, while intramuscular injections carry a three percent to 24 percent risk of the same.Tardive dyskinesia will affect anywhere from two percent to six percent of Risperdal users, depending on the formulation.Parkinsonism can affect as few as six percent to as many as 28 percent of users. It is important to advise your doctor if you experience any involuntary muscle movements or have a loss of muscle control while taking Risperdal. If left untreated, conditions like tardive dyskinesia may become permanent. Serious Side Effects On rare occasions, exposure to atypical antipsychotics may result in a potentially life-threatening reaction known as a neuroleptic malignant syndrome (NMS). It is a condition characterized by the following symptoms: Altered mental stateHigh fever (over 100.4 F)Loss of bladder controlMuscle rigidityProfuse sweatingRespiratory problemSeizuresTachycardia (rapid heartbeat) Once symptoms appear, they tend to progress rapidly and can persist for anywhere from eight hours to over a month. For reasons unknown, NMS tends to affect men under 40 more than any other group.?? NMS is considered a medical emergency and can lead to death if left untreated. Treatment would be administered in an intensive care unit, often with mechanical ventilation, intravenous fluids, and a variety of medications used to reduce muscle rigidity, agitation, and other symptoms. Even with treatment, as many as 10 percent of NMS cases will result in death. Other Serious Complications Other rare but potentially life-threatening side effects may occur with Risperdal use. Most are associated with either overuse or long-term use of the drug. They include: Diabetic ketoacidosis (a dangerous build-up of acids in the blood)Pancreatitis (inflammation of the pancreas)Pulmonary embolism (the formation of a blood clot in the lungs)StrokeSudden cardiac death

Stream Order - The Classification of Streams and Rivers
One of the most important aspects of physical geography is the study of the worlds natural environment and resourcesââ¬âone of which is water. Because this area is so important, geographers, geologists, and hydrologists alike use stream order to study and measure the size of the worlds waterways. A stream is classified as a body of water that flows across the Earths surface via a current and is contained within a narrow channel and banks. Based on stream order and local languages, the smallest of these waterways are also sometimes called brooks and/or creeks. Large waterways (at the highest level the stream order) are called rivers and exist as a combination of many tributary streams. Streams can also have local names such as bayou or burn. How It Works When using stream order to classify a stream, the sizes range from a first-order stream to the largest, a 12th-order stream. A first-order stream is the smallest of the worlds streams and consists of small tributaries. These are the streams that flow into and feed larger streams but do not normally have any water flowing into them. Also, first- and second-order streams generally form on steep slopes and flow quickly until they slow down and meet the next order waterway. First- through third-order streams are also called headwater streams and constitute any waterways in the upper reaches of the watershed. Over 80% of the worldââ¬â¢s waterways are estimated to be these first- through third-order or headwater streams. Going up in size and strength, streams that are classified as fourth- through sixth-order are medium streams, while anything larger (up to 12th-order) is considered a river. For example, to compare the relative size of these different streams, the Ohio River in the United States is an eighth-order stream while the Mississippi River is a 10th-order stream. The worldââ¬â¢s largest river, the Amazon in South America, is considered a 12th-order stream. Unlike the smaller order streams, these medium and large rivers are usually less steep and flow more slowly. They do however tend to have larger volumes of runoff and debris as it collects in them from the smaller waterways flowing into them. Going Up in Order If, however, two streams of different order join neither increases in order. For example, if a second-order stream joins a third-order stream, the second-order stream simply ends by flowing its contents into the third-order stream, which then maintains its place in the hierarchy. Importance Stream order also helps people like biogeographers and biologists in determining what types of life might be present in the waterway. This is the idea behind the River Continuum Concept, a model used to determine the number and types of organisms present in a stream of a given size. More types of plants, for example, can live in sediment-filled, slower flowing rivers like the lower Mississippi than can live in a fast-flowing tributary of the same river. More recently, stream order has also been used in geographic information systems (GIS) to map river networks. The algorithm, developed in 2004, uses vectors (lines) to represent the various streams and connects them using nodes (the place on the map where the two vectors meet.) By using the different options available in ArcGIS, users can then change the line width or color to show the different stream orders. The result is a topologically correct depiction of the stream network that has a wide variety of applications. Whether it is used by a GIS, a biogeographer, or a hydrologist, stream order is an effective way to classify the worldââ¬â¢s waterways and is a crucial step in understanding and managing the many differences between streams of different sizes.

Use Of Traditional Chinese Medicine During The Treatment...
The Use of Traditional Chinese Medicine in the Treatment of Schizophrenia Shoanie Young Spring 2015 Part I: Biomedical Perspective Introduction Schizophrenia is a complex psychotic disorder evident by impaired thinking, emotions, judgment and behaviors. The personââ¬â¢s grasp of reality may be so disordered that they are unable to filter sensory stimuli and may have intense perceptions of sounds, colors, and other features of their environment. Although there are different levels of severity in symptoms, the Gale Encyclopedia of Medicine (Fundukian, Ed., 2014) states that schizophrenia may typically interfere with a person s ability to think clearly and to know the difference between reality and fantasy. People with schizophrenic symptoms have hallucinations and delusions, and often have difficulty with everyday life. It is a complicated disease that is not well understood and carries significant stigma for its sufferers. The prevalence of schizophrenia is thought to be about 1% of the population around the world. The disorder is considered to be one of the top ten causes of long-term disability worldwide. Late adolescence and early adulthood are periods for the onset of schizophrenia. In 40% of men and 23% of women diagnosed with schizophrenia, the condition manifested before the age of 19 (Addington, Cadenhead, Cannon, 2007).These are critical years in a young adultââ¬â¢s social and vocational development.

Types of Story Leads Free Essays
Lead Every news story begins with an introduction called the lead. This may be a single word, a phrase, a clause, a brief sentence, an entire paragraph or a series of paragraphs. The main functions of the lead, aside from introducing the news story, are to tell the story in capsule form and to answer right away the questions the reader would naturally ask. We will write a custom essay sample on Types of Story Leads or any similar topic only for you Order Now A good lead answers all the important questions of the reader, indicates the attendant circumstances if they are all important, and arouses the readersââ¬â¢ interest to continue reading the story. The lead is the beginning, the most important structural element of a story. Charnley (1966) stated that, ââ¬Å"an effective lead is a brief, sharp statement of the storyââ¬â¢s essential facts. â⬠The lead is usually the first sentence, or in some cases the first two sentences, and is ideally 20-25 words in length. Leads should: * open with bright, interesting, colorful nouns and verbs be brief (often only 20-30 words) be, for the most part, one sentence in length be crisp and to the point effectively summarize the story ââ¬Å"feature the featureâ⬠include attribution (the source) if needed for credibility ive the title for any person mentioned not include personal pronouns such as ââ¬Å"weâ⬠and ââ¬Å"youâ⬠not include reporter opinion Summary lead The typical lead is called a summary lead or straight summary lead, and it, of course, summarizes the story. The journalist must, therefore, write a clear, fairly short sentence that reveals all, telling the end result of the story. Someone should be able to read the lead and be informed about what happened without reading the rest of the story. A summary lead should answer as many of the 5Wââ¬â¢s and H as possible: who, what, when, where, why and how. The 5 Wââ¬â¢s and H provide the news writer with quick and convenient means of organizing the lead of a story. They also provide the framework or structure for organizing the lead of a story. This is one of the most common forms of hard news story. But, the question is that how do we decide what is most important and what should follow in descending order of importance? Here, we must use our own judgment. Some questions to ask: What will affect the readers the most? What questions does the lead raise that need to be answered immediately? What supporting quotes are strongest? Below are examples of leads which feature the various 5Wââ¬â¢s H. The words that make up the ââ¬Å"Wâ⬠that is featured are in bold face type. | WHO lead Used when the person involved is more prominent than what he does or what happens to him. -Reckless drivers who donââ¬â¢t seem to be drunk may well be high on cocaine or marijuana, according to roadside tests that indicate drugs may rival alcohol as a hazard on the highway. -Monica Lewinsky, the former low-level aide at the center of the current White House investigation, is willing to submit to a polygraph examination in exchange for complete immunity from prosecution, her lawyer said Sunday. WHAT lead Used when the event or what took place is more important than the person involved in the story. -A pack of wild monkeys terrorized a seaside resort town south of Tokyo last week, attacking 30 people and sending eight of them to the hospital with bites. (This also co-features the who. ) -A Soyus spacecraft docked flawlessly with the Mir space station Saturday, bringing a fresh crew of two Russian cosmonauts and a Frenchman to the orbiting outpost ââ¬â along with a bottle of French wine. WHY lead Used when the reason is more prominent or unique than what happens. With more amateurs cutting wood for use as an alternative to high-priced heating oil, hospitals are coping with an increasing number of injuries due to chain-saw accidents, reported the American College of Surgeons. WHERE lead Used when the place is unique and no prominent person is involved. -Red China will be the site of the next International Film Festival. WHEN lead Rarely used as the reader presumes the stor y to be timely. However, this lead is useful when speaking of deadlines, holidays and important dates. -Today, almost to the hour, the Revolutionary Government was proclaimed by President Corazon Aquino. HOW lead Used when the manner, mode, means, or method of achieving the story is unnatural way. -Louisiana-Pacific Corp. plans to sell seven out-of-state lumber mills and expand production at 17 others in order to boost output by up to 40 percent. (The how in this lead is also the what. ) Novelty leads Novelty leads differ fromà summary leads inà that they make no attempt to answer all of the five Ws and the H. Asà theà nameà implies noveltyà leads are novel. They à use à different à writing à approaches à to à present different à news à situations à to à attract à the à readerââ¬â¢s à attention and à arouse à curiosity. Type of Novelty Lead| Example| CONTRAST: The contrast lead compares two opposite extremes, generally dramatize a story. The comparisons most frequently used are tragedy with comedy, age with youth, the past with the present and the beautiful with the ugly. | In 1914, the United States entered the First World War with a Navy of 4,376 officers, 68,680 men, 54 airplanes, one airship, three balloons and one air station. Today, there are more than 500,000 active duty officers and enlisted personnel, 475 ships and 8,260 aircraft in our Navy.

I t allows the reader to see the person or thing as you saw it. | Thin and unshaven , his clothes drooping from his body like rags on a scarecrow, Frank Brown, USN, today told naval authorities about six-week ordeal in an open rubber boat in the South China Sea. The new principal, although only at his early thirties, is already silver-haired. He seldom talks, but when he does, he talks with sense. | FREAK: The freak lead is the most novel of the novelty leads. As the name implies, the freak lead employs a play on words, alliteration, poetry or an unusual typographical arrangement to introduce the facts in the story and to attract the readerââ¬â¢s attention. | For sale: One guided missile destroyer. The Navy is thinking about inserting this advertisement. â⬠¦ $ammy $mith, who i$ just $even, wa$ digging in the $and at $amsons beach today and gue$$ what he found? | BACKGROUND: The background lead is similar to a picture lead, except for one important difference.

Use Of Satire In Huck Finn Essays - English-language Films
Use Of Satire In Huck Finn The journey taken by two people down a river, is rarely thought of as anything more than just an adventure. However, Mark Twain uses his novel, The Adventures of Huckleberry Finn, to explore and poke fun of many problems facing American society. Huck, the main character, is considered an uneducated boy who is constantly under pressure to conform to the civilized aspects of society. Jim, who accompanies Huck, is a runaway slave seeking freedom from the world that has denied it to him for so long. In his novel, Twain uses satire to demonstrate many of civilizations problems. In the beginning of the story, Huck sneaks away from his home to play with Tom Sawyer and his friends. The boys start a gang and decide that one of the things they will do is kidnap people, and hold them for ransom. The boys quickly discover that they cannot ransom anyone because they don't know what ransom means. Tom has a theory as to the meaning of the word, But per'aps if we keep them till they're ransomed, it means that we keep them till they're dead.(12) Without any doubts, all of the boys agree with this meaning of the word. In this segment of the novel, Twain uses satire to demonstrate that even though something may be truly wrong, if civilization or society adopts it to be true, then it is believed to be true. Twain may be specifically using the issue of slavery as his target, in this instance of satire. During the time period in which The Adventures of Huckleberry Finn was written, religion was as much a part of civilization, as was an education. Religion is one of the key victims of Twain's satire throughout the novel. This satire is no more apparent then when Huck's guardian, the Widow Douglas, preaches to him about Moses. Huck didn't think very much of her lecture; Here she was a-bothering about Moses, which was no kin to her, and no use to anybody, being gone, you see...(3) Twain uses Huck to exhibit his objection to the blind faith that civilized society places towards religion. During Huck and Jim's journey, they encounter two men who refer to themselves as the Duke and the King. Theses characters make their living by swindling people out of their money. When they are eventually caught, they pay for their sins by being tarred and feathered. Huck expresses his thoughts on the subject by saying, It was a dreadful thing to see. Human beings can be awful cruel to one another.(294) Through this event, Twain shows that crooks and criminals aren't the only ones that can be cruel. The crowd that considers themselves to be civilized and opposing any such imprudent and cruel acts, actually commits one themselves. Twain illustrates how a society that views themselves as civilized can display such irresponsible conduct. Twain uses a boy and a runaway slave in, The Adventures of Huckleberry Finn, to not only tell a story, but to express what he thinks are the problems of civilized society. Satire is the key tool in which he uses to demonstrate these problems. Through Twain's use of satire, we can not only poke fun at American society, but we can learn from its mistakes. Twain turned an ordinary adventure down a river into an exploration of the problems society, especially civilized society, faces. Because of the brilliant way in which Twain intertwines satire into his novel, the lessons in The Adventures of Huckleberry Finn, will be remembered forever.

How to Prepare for a Timed Writing Exam Timed essays are a favorite for standardized tests and college exams. They not only test your knowledge, but they test your ability to develop a coherent argument under pressure. The secret to a timed writing exam is preparation beforehand and avoiding rushing on the day of the exam. Here are some tips on how to write a great timed essay. Manage Your Stress One cause of poor performance on timed essays is anxiety. There are lots of scientific studies that show how anxiety affects brain function. If youââ¬â¢re stressed while reading the prompt, you may not even be able to understand it, let alone formulate a good response to it. If you feel yourself starting to panic when the proctor or professor starts the clock, take a moment to calm yourself down. Close your eyes. Take a few deep breaths. Count to twenty. Then slowly open your eyes and with a calm mind start reading the essay prompt. Another thing that helps with stress is preparation. Find out which things can make you fail and how to avoid them! Do Some Practice Runs You wonââ¬â¢t know the topic beforehand, but if you actually sit down and do a couple of practice essays on some plausible topics, youââ¬â¢ll be able to see where your weaknesses lie and how you can address them. For example, did you rush into the writing without thinking it through first? Did you need to go back and revise? Did you have enough time to make a sensible revision? Practicing first will not only help you remain more calm when itââ¬â¢s show time, it will also help you learn to pace yourself. Think Before You Write After reading the topic, give yourself some time to let your thoughts on it formulate. If you jump right in to your first idea, you may miss an opportunity to write an even better, more well-formed essay. A good way to decide what to write is to jot down notes on the different ideas that come up and then choose which one you think is the best one. Make an Outline Again, resist the urge to just start scribbling and dedicate time to preparing your essay first. Making an outline where you line up the points you wish to touch on will help guide your writing. It will also prevent you from forgetting what you wanted to say, a common problem with timed essays due to stress and pressure. Make Sure Youââ¬â¢re Answering the Question Another common pitfall to avoid is failing to address the prompt. Again, this problem can be circumvented by slowing down. While making your outline, keep referring to the prompt. Does each part of your outline answer it? If not, what has to be changed to make sure you stay on course? Donââ¬â¢t Write Filler Even though this is a timed essay, you should dedicate your efforts to writing quality statements. Donââ¬â¢t write just to fill the space. This can be particularly tempting when writing the introduction which is where itââ¬â¢s most important for you to get to the point. Your thesis statement at the end of your introductory paragraph should be well-defined and strong. This will help the flow of the rest of your essay so give it your best effort. Revision Tips What if you followed all of the above advice but in the middle of writing had a new idea that would change your essay? Here you have to make a decision. Is the new idea so much better that it warrants changing your essay structure for it? AND do you have enough time to revise completely? If so, then go back and revise the parts youââ¬â¢ve written so far. If youââ¬â¢re writing on paper, make sure you skip a line to leave room for revisions. On a computer, itââ¬â¢s much easier to revise, but you also run the risk of deleting work you wish to use later. If youââ¬â¢re revising on a computer, put the parts you want to take out in brackets. After youââ¬â¢ve finished writing and are doing a final edit, go back and take out the parts that are unnecessary.

A Guide to Caring for Pet Millipedes
A Guide to Caring for Pet Millipedes If youve never cared for an arthropod pet before, a millipede is a good first choice. Millipedes are herbivorous, so they are easy and inexpensive to feed. Theyre fairly low maintenance pets and can be handled even by young children, with supervision, of course. Many pet stores sell African giant millipedes, which grow to 10 inches or more in length. You can also try keeping millipedes you collect in the wild, but keep in mind that brightly colored millipedes usually secrete hydrogen cyanide, which can cause an unpleasant burning sensation on sensitive skin. Things You Should Know About Keeping Pet Millipedes Before bringing home any live animal, its important to know what to expect. Does a millipede require a lot of care? Can you keep more than one in the same enclosure? Do they bite or sting? Though pet millipedes are a good choice in most circumstances, you should weigh the pros and cons of keeping them before you bring one home. Choosing a Millipede at the Pet Store As with any pet, its important to choose a healthy individual. In general, millipedes have few health issues, and youre unlikely to find sickly millipedes at your local pet store. Still, its good to know how to recognize an unhealthy millipede before you make a purchase, so you can avoid problems once you bring one home. Housing Your Pet Millipede The key to caring for millipedes successfully is to provide them with the appropriate habitat. Millipedes require ample floor space, while the height of the terrarium is less important. You can use a number of different materials for the substrate. An appropriate water source for your millipede is important as well. Maintaining the Proper Environment for Your Pet Millipede Most large millipedes you can purchase from pet stores or science catalogs come from the tropics. They require a higher temperature and humidity level than other arthropods commonly kept as pets. All pet millipedes need adequate moisture, which means you must use a proper substrate and mist the terrarium regularly. Feeding Your Pet Millipede The herbivorous millipede will happily munch on almost any fruit or vegetable you offer, although they do have favorites. They also require calcium in their diets in order to molt and grow properly. Youll need to know how to prepare their food, how to supplement their diet with calcium, and how often to feed them. Handling Your Pet Millipede Even a millipede can feel nervous! You should always strive to keep your millipede feeling secure and comfortable, even when you are handling it. Its also important to know how millipedes defend themselves, in the event your pet millipede does feel threatened in your hands.

Travel in South Africa Essay Example | Topics and Well Written Essays - 1000 words
Travel in South Africa - Essay Example The country is characterized by world class infrastructure, friendly citizens as well as spectacular scenery. This sector received a major boost during the 2010 world cup when it received the highest number of visitors in history. There are various benefits associated with the industry in South Africa. Tourism and travel provides foreign exchange for the country. This gives the governments enough money to offset the foreign debts, allows the South African Rand to remain at par with the US dollar. It also allows the government to pay its employees (Walker and Keith 15). This means that governments have money that is dedicated towards constructive projects such as education, infrastructure as well as health care. The South African citizens that go for shopping sprees abroad have the money to buy goods and services as long as the foreign currencies are readily available in the economy (Walker and Keith 22). Finally, tourism and travel facilitates exportation of goods into the country. Tourism and travel leads to the direct and indirect creation of jobs. When tourists visit the country, it leads to job creation for jewelry trades, drivers and vendors that are directly involved in the sector (Walker and Keith 33). Tourism and travel also has an indirect impacts on landlords and other traders. The sector plays a key role in ensuring job creation in the hotel and entertainment industries. As earlier stated the tourism and travel sector employs one out of every twelve individuals in the economy. The tourism sector contributes towards infrastructure development as the government works towards developing roads, electricity and communication networks in the country to attract tourists. This results into an infrastructure improvement in the country (Walker and Keith 67). The tourist and travel sector results into cultural preservation through economic and cultural incentives. Finally, it results

Malcolm X and Martin Luther King Essay Example | Topics and Well Written Essays - 750 words
Malcolm X and Martin Luther King - Essay Example Though these men seemed to be polarized in their approach to the civil rights movement, they were linked by the common bond of instilling a sense of extreme urgency, the possibility of violence, and a demand for justice for their followers. Though Malcolm X has been characterized as being far more radical and violent than King, this is a misconception. King understood the violence that would be involved in the struggle and the protest marches he led were marked by extreme violence. He also knew that the fight must be viewed as violent without the blacks being seen as the perpetrators. In King's speech "I May Not Get There With You", he warns, "There will be neither rest nor tranquillity in America until the Negro is granted his citizenship rights. The whirlwinds of revolt will continue to shake the foundations of our nation until the bright day of justice emerges" (cited in Dyson 2000 p.18). It is this type of rhetoric that forced the government to choose sides and illuminated their official stand as white racist (O'Reilly 1989 p.155). These were attitudes that were no less radical than Malcolm X professed. Just as King has been mischaracterized as a pacifist in the civil rights movement, so has Malcolm X been portrayed as more radically violent than he actually was. Movies and anecdotal recollections of people involved with Malcolm X only serve to heighten this slant in the history of the man. Yet Marable (2006) contends that Malcolm X's own writings confirm that at the time of his death he was proposing, "... an unprecedented African-American united front of black political and civic organizations, including both the Nation of Islam and other civil rights groups" (p.157). This aspect of Malcolm X is often overlooked by historians and relates his depth of commitment to the struggle for equal rights and not separate rights. The portrayal of Malcolm X as a black nationalist denies his later years as a black activist that was working for equal justice and the elevation of the dignity of the black population within white America. Both men approached the civil rights movement with a sense of urgency. Yet, once again history and the media have polarized the common perceptions of the men. King has been portrayed as a patient agent working for incremental change while Malcolm X has been viewed as an advocate for violent revolution. Yet both men used the underlying threat of violence beyond their control to effect their ends. In King's speech "Beyond Vietnam - A Time to Break Silence" (1967), he warns America, "We are now faced with the fact, my friends, that tomorrow is today. We are confronted with the fierce urgency of now". This sense of immediacy also resonated in Malcolm X's "do it yourself philosophy, a do it right now philosophy, an it's already too late philosophy" (qtd. in Baynes 2006). These were reminders to the opposition that they might not be able to restrain their followers for any extended time if their demands were not addressed (Walton 1972 p.85). Clearly both men were using the demand of urgenc y and its subtle hints of the portending violence that it brought to highlight and further their cause. In conclusion, both King and Malcolm X realized that the struggle for

Nanotechnology In Architecture
Nanotechnology In Architecture Historically and geographically human have lived in extremely varied technology or environment and have had to adapt to comfort habitats and thus the architects have had to manage the ideal of design as well as incorporate the evolutionary technology. A technology has evolved to a level where it is just too complex. Sometimes satisfying the need of the user and sometimes becoming too dangerous when the negative consequences are not taken care of. For example, the issues of the Large scales in architecture is one such matter which has been partially solved with the help of low cost materials, energy savingà ¢Ã¢â ¬Ã ¦etc. The scientists have developed and are continuing to develop nanotechnology to help architects incorporate more artificial intelligence in construction. Nanotechnology is a combination of various fields of science like, Bio- technology, Chemistry, Physics, Bio-informatics, etc. There are three chief divisions in Nanotech: Nanoelectronics, Nanomaterials, and Nano-Biotechnology. Worldwide, there is much enthusiasm about nanotechnology as it has application in medicine, electronics, biomaterials, energy etc. It is observed that US, Japan, and Germany dominate the current RD effort in nanotechnology with a focus on they own expertise and needs (Hyd and spook, 2012). The use and control of the technology at an atomic or particle scale known as nanotechnology has started to have its impact like never before in materials of constructions and has immense futurist impact in architecture, this application of the nanotechnology and nanomaterials in architecture is NanoArchitecture. The nano world in technology is a real challenge for todays designers, it started with an understanding and control of the technology and materials on one billionth (10-9) scale. The understanding of these materials, its use in architecture to be profitable for users and its implication on the building (Construction) are some of the key aspect for inquiry in this dissertation. With the perfect solution of this dilemma, the Architects would not only know how big their task is but how it might lead to new ways of thinking architecture. After understanding the meaning and origin of this technology, we will study certain aspects that is a must in todays constructions and then we see the direction where this science is going, we will also look at the ways to incorporate these technologies in our architecture, therefore the question that will guide our research is how does nano (technology, materials, science, concept, form and function) become important to the level of influencing architects (designers). Nanotechnology is developed in the manner that it is active or passive, this repartition will lead us to a large study but our focus will rely on the relation passive active nanostructure and application of nanotechnology in a building design and construction. Passive nanotechnologies, such as nanocoatings, nanoparticles, and nanostructured materials, are already available. Second generation active nanostructures, for example, nanoelectro-mechanical systems, nanomachines, self-healing materials, and targeted chemicals, can evolve their properties, structure and/or state during their operation. This could increase nanotechnologys impacts and require new approaches for risk assessment. Active nanostructures are likely to have a different and increased profile of impacts (including benefits as well as potential risks) compared with passive nanotechnologies. RESEARCH QUESTION: How does nano (technology, materials, science, concept, form and function) becomes important to the level of influencing architects (designers). NEED IDENTIFICATION: Over the years the materials used in buildings (during construction, inside or outside finishes) has been of a large scale, the evolution today have brought into existence the materials on a microscopic scale with even more value to life and building. They can be metals, ceramics, polymers or composites. Known as nanomaterials, nanocomposites, and manufactured nanomaterials (MNMs), the method of making these materials begins at the molecular or atomic level, sometimes creating new products with extraordinary physical and chemical properties. For example, a carbon nanotube has strength of 150 times that of steel but is approximately six times lighter. Besides strength enhancement, properties can include self-cleaning, super hardness, electrical conductivity, antimicrobial superior thermal resistance and stability, non-flammability, lightweight, anti-corrosion, superior barrier, light emitting and low permeability, among others. Applications in the building industry include use as fire retardants, high performance insulation, protective coatings, equipment lubricants, structural integrity enhancement and monitoring, photovoltaic, stronger tensile cables, and self-cleaning or heat absorbing windows ( CFN, 2011 )à ¢Ã¢â ¬Ã ¦ Using these materials which contain extraordinary application in the building can also bring amazing influences to the architect, designer or the design. Therefore apart from attempting to understand the transformation that the nanotechnology brings to our building there is a need to understand by students the uses of nanotechnology for creating better design. SCOPE: à ¢Ã¢â ¬Ã ¢ A general understanding of nano especially toward architecture à ¢Ã¢â ¬Ã ¢ Nanotechnology (materials) applications in buildings à ¢Ã¢â ¬Ã ¢ Concept; form and function derived from nano LIMITATION: à ¢Ã¢â ¬Ã ¢ The laboratories details of certain materials and nano applications in medical branches will not be part of our research. à ¢Ã¢â ¬Ã ¢ This research dissertation will have some limitation in details like calculations, manufactures process, chemical components. à ¢Ã¢â ¬Ã ¢ Thinking in more detail about how to use nanomaterials in a design context, a first consideration is simply to define what is being design?. But there is a lack of built case studies, so we will rely on existing, futurist, basic concept and reading materials. à ¢Ã¢â ¬Ã ¢ Regarding the size of this matter nanotechnology, we will limit at the level where nanotech is active and very briefly talk about the passive Nanotechnology RESEARCH METHODOLOGY: N A N O A R C H I T E C T U R E PART O. COLLECT RELEVANT DATA This methodology starts with a basic understanding (through various sources) of nano technology specially its applications in the materials and its relation with form and function in architecture.

The reading of the applications in nanotechnology in todays constructions is more related to Green designers, this part of the design has an impact in the ecology and climate control therefore the green rated buildings has in fact a considerable amount of nanotechnology use in it. This leads us to refer to architects involved in green concepts or sustainability from LEED etc ( Ar Alex Nyembo Kalenga) and also we could make a visit studies on the actual certified Green building Rajiv Gandhi urja Bhavan at Vasan Kunj New Delhi Still in Construction. A list of questions has guided our study and survey interview in which the answers are include to our conclusion of this research: 1. A personal understanding of Nanotechnology or Nanoarchitecture. 2. If any specific material at a nano scale is used to improve certain aspects in the building, such as: Insulation reduction Lighting Energy storage Air purification Water management 3. How do you think buildings designed exclusively on scientific principles of Nanotechnology will affect their occupants? 4. Does Nanotechnology have an impact on todays practicing architects If yes; at what scale does it influence them? Any example? If not; Why so? Secondary Case study The conceptual level derived of the interpretation of nano differs from an architect to another. 1. Two typology of this nano buildings as guided this part of the research: 5.

Fundamental Knowledge II.1.1. WHAT IS NANOTECHNOLOGY? A brick is the smallest building block in construction. Whatever you do, the strength of the building is limited to the strength of the brick. The brick itself is made of minute particles of clay bonded together. One has limited control over how the particle of clay forms. Each particle of clay in turn is formed from molecules joined together in a particular pattern dictated by the forces of nature. What happens if it is possible to arrange these molecules in a pattern that provides greater strength? You get stronger clay and a stronger brick. This results in a much thinner, but stronger wall. This technology of arranging molecules the way we want is a basis of nanotechnology. (Johnzactruba, 2011) A strict definition of nanotechnology characterizes it as the manipulation of a matter at the scale of one-billionth of a meter or smaller. The measurement of one-billionth of a meter is identified as one nanometer (nm) (Jeffrey H. Matsuura,1957). Nano, is a word which does not only mean billionth less but also leaves a billionth of question in mind, because of the complexity to understand its simplicity. It is a world hold by the scientist, chemist and physicians. Yes nanotechnology is a relatively recent development in scientific research but not new. The level of its study and diversity has involved touching now many sector of life and becoming more and more known by the public. The concept first was introduced by American physicist Richard P. Feynman (1918-1988). But it is noted that in the 10th centuries the 16th centuries the ruby-red color of many stained-glass windows from the medieval era was a consequence of embedded nanoscale metallic particles within the glass. There were no scientific understanding of these phenomena at the time, nor were there deliberate attempts to produce what we now know as nanomaterials. Early knowledge relied on craft-based trial and error to achieve effects we must keep in mind, however, that not all interesting color phenomena are a result of embedded nanomaterials ( Michael F. Ashby, 2009). The evolution of nanotechnology has been more or less in the domain of chemical, medicine and physics (technique) then it involved to the environment, energy, agriculture, communication and information because of some of its advantage and disadvantage in the society. The main tools used in nanotechnology are three main microscopes: Transmission Electron Microscope (TEM), Atomic Force Microscope (AFM), and Scanning Tunneling Microscope (STM). (Jamie Jackson, CIS 121) II.1.2. NANO PRODUCTS Use as gateways to build other nano products, Nanosensors can be chemical sensors or mechanical sensors. Amongst other applications they can be used: à ¢Ã¢â ¬Ã ¢ To monitor physical parameters such as temperature, displacement and flow à ¢Ã¢â ¬Ã ¢ As accelerometers in Microelectromechanical systems (MEMS) devices that can rapidly and remotely detect change in their surroundings like airbag sensors à ¢Ã¢â ¬Ã ¢ For medical diagnostic purposes either as blood borne sensors or in lab-on-a-chip type devices à ¢Ã¢â ¬Ã ¢ To detect various chemicals in gases for pollution monitoring à ¢Ã¢â ¬Ã ¢ Sensors using carbon nanotube detection elements are capable of detecting a range of chemical vapors. These sensors work by reacting to the changes in the resistance of a carbon nanotube in the presence of a chemical vapor ( Hawks Perch Technical Writing, 2007). II.1.2.1. Nanotube Known as well as Carbon Nanotube (CNTs), it is a tube-shaped material or cylindrical nanostructure made of carbon, having a diameter of nanometer scale. Nanotubes form a tiny portion of the material(s) in some baseball bats, golf clubs, or car parts. Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively. In 2000, a multi-walled carbon nanotube was tested to have a tensile strength of 63 gigapascals (GPa). Since carbon nanotubes have a low density for a solid of 1.3 to 1.4 g/cm3, its specific strength of up to 48,000 kNà ¢Ã¢â ¬Ã ¢mà ¢Ã¢â ¬Ã ¢kgà ¢Ãâ ââ¬â¢1 is the best of known materials, compared to high-carbon steels 154 kNà ¢Ã¢â ¬Ã ¢mà ¢Ã¢â ¬Ã ¢kgà ¢Ãâ ââ¬â¢1. Standard single-walled carbon nanotubes can withstand a pressure up to 24GPa without deformation. The bulk modulus of super hard phase nanotubes is 462 to 546 GPa, even higher than that of diamond (420 GPa for single diamond crystal) and can produce materials with toughness unmatched in the man-made and natural worlds. Because of the carbon nanotubes superior mechanical properties, many structures have been proposed ranging from everyday items like clothes and sports gear to combat jackets and space elevators. However, the space elevator will require further efforts in refining carbon nanotube technology, as the practical tensile strength of carbon nanotubes can still be greatly improved (Wikipedia, 2012). II.1.2.2. Nanocomposites The definition of nano-composite material has broadened significantly to encompass a large variety of systems such as one-dimensional, two-dimensional, three-dimensional and amorphous materials, made of distinctly dissimilar components and mixed at the nanometer scale (Kanatzidis, 2006). New materials with novel proprieties are generate rapidly through this field. The properties of nano-composite materials depend not only on the properties of their individual parents but also on their morphology and interfacial characteristics. Although nanoscale reinforcements (or nanofillers) of nanocomposites have different kinds of fillers such as nanofibers, nanowires, nanotubes and nanoparticles etc, their mechanical behaviors have some common features. As the figure shows a potential use of nanocomposites as multifunctional materials (Journal Club, 2008). AREA OF APPLICATION Such mechanical property improvements have resulted in major interest in nanocomposite materials in numerous automotive and general/industrial applications. These include potential for utilisation as mirror housings on various vehicle types, door handles, engine covers and intake manifolds and timing belt covers. More general applications currently being considered include usage as impellers and blades for vacuum cleaners, power tool housings, mower hoods and covers for portable electronic equipment such as mobile phones, pagers etc (Professor J.N. Hay, 2001). The inorganic components can be three-dimensional framework systems such as zeolites, two-dimensional layered materials such as clays, metal oxides, metal phosphates, chalcogenides, and even one-dimensional and zero-dimensional materials such as (Mo3Se3-)n chains and clusters. Experimental work has generally shown that virtually all types and classes of nanocomposite materials lead to new and improved properties when compared to their macrocomposite counterparts. Therefore, nanocomposites which combine new nanomaterials with more traditional ones such as steel, concrete, glass, and plastics, can be many times stronger than standard materials and promise new applications in many fields such as mechanically reinforced lightweight components, non-linear optics, battery cathodes and ionics, nano-wires, sensors and other systems. On the market there already a nanocomposite steel that is three times stronger than conventional steel. Before long, nano-reinforced glass might be used for both structure and enclosure. In the some student projects in the nanoSTUDIO at Ball State University, nanotube structural panels create transparent load-bearing curtain walls free of columns and beams, quantum dots make walls and ceilings light up or change color with the flip of a switch, and nanosensors in building components create smart environments that constantly adapt to their environment and users. II.1.3. TYPOLOGY M. C. Roco, one of the driving forces behind the NNI, has developed a more detailed typology of nanotechnologies. He identifies four generations of nanotechnologies: passive nanostructures, active nanostructures, systems of nanosystems and molecular nanosystems (J. Clarence, 2009) ( Fig04: For generation of nanotechnology development, Center for Responsible Nanotechnology ) Each generation of products is marked by the creation of commercial prototypes using systematic control of the respective phenomena and manufacturing processes. Products may also include components which correspond to different generations. Todays rudimentary capabilities of nanotechnology for systematic control and manufacture at the nanoscale are expected to evolve significantly in both complexity and the degree of integration by 2020. II.1.3.1 Passive to Active nanotechnology It has been suggested that an important transition in the long-run trajectory of nanotechnology development is a shift from passive to active nanostructures. Such a shift could present different or increased societal impacts and require new approaches for risk assessment. An active nanostructure changes or evolves its state during its operation, according to the National Science Foundations (2006) Active Nanostructures and Nanosystems grant solicitation. Passive: (steady function) nanostructures Behaviour: inert or reactive nanostructures which have stable behaviour and quasi -constant properties during their use. Potential risk: e.g. nanoparticles in cosmetics or food with large scale production and high exposure rates. Active: (evolving function nanostructures) Behaviour: the nanostructures properties are designed to change during operation so behaviour is variable and potentially unstable. Successive changes in state may occur (either intended or as an unforeseen reaction to the external environment). Potential risk: e.g. nanobiodevices in the human body; pesticides engineered to react to different conditions. Categories of active nanostructures are: à ¢Ã¢â ¬Ã ¢ Remote actuated active nanostructures, such as light-actuated embedded sensors; à ¢Ã¢â ¬Ã ¢ Environmentally responsive active nanostructures, such as responsive drug delivery; à ¢Ã¢â ¬Ã ¢ Miniaturized active nanostructures, such as synthetic molecular motors and molecular machines; à ¢Ã¢â ¬Ã ¢ Hybrid active nanostructures, or uncommon combinations of materials, such as silicon-organic ; à ¢Ã¢â ¬Ã ¢ Transforming active nanostructures, such as self-healing materials. (M.C. Roco, 2004, 2007) Tour estimates the time it will take to commercialize each of these types as 0-5 years for passive nanotechnologies, 15-50 years or more for active nanotechnologies and 7-12 years for hybrids (J. Clarence, 2009) II.1.4. WHY ALL THE FUSS ABOUT NANOTECHNOLOGY? NANOTECHNOLOGY: THE SCIENCE CHANGING YOUR LIFE Penny Sarchet The advantages of using nanomaterials in construction are enormous. When you consider that 41 percent of all energy use in the United States is consumed by commercial and residential buildings, the potential benefits of energy-saving materials alone are vast (Dr. Pedro Alvarez of Rice University, 2010) and when we have to evaluate the energy used by buildings in the rest of the world the result will surly show that the use of the nanomaterials in buildings will be of an anxiety necessity. Nanotechnology thus has profound potential because it can free us from some traditional limits and offer us useful new capabilities. Nanotechnology can change some of the physical rules that have traditionally confined us. It can also free us from some of the limitations that have long been placed upon us by size ( Jeffrey H, 1957). The key is to understand the specific risks and implications of the product before it is widely used. This way we can ensure that nanotechnology evolves as a tool for sustainability rather than as an environmental liability (Dr. Pedro Alvarez of Rice University, 2010). Benefices and profit with the nanotechnology is now in the hand of everyone and architects are with no doubt going to shape this realm to another level. e.g.: Solera enables seamless integration of natural daylight into the design and function of buildings. Well daylighted spaces deliver substantial and measurable benefits to sustainability, energy efficiency and human performance. This series of products provide architects with solutions to solve the challenges traditionally associated with daylighting techniques including solar heat gain, cost, complexity and glare. Other materials such as brickà ¢Ã¢â ¬Ã ¦ have already showed us the changes that it has done to the industries, life, designers, buildersà ¢Ã¢â ¬Ã ¦ In the early days, paint was available in a limited variety of colors for you to choose. Now most of the paint shops have mixers that allow the users to choose the color they require. The manufacturers have to produce and stock only a few basic colors, reducing production and inventory costs at much greater satisfaction to the consumer. The future of nanotechnology will be the personal nano-factories, like the paint mixers, that allow you to produce any material that you require. The shops have to carry only stock in molecular form. Advances in nanotechnology are moving at an exponential rate. It will eventually encompass every field of human activity including energy. (Johnzactruba, 2011) Disadvantages of Nanotechnology: Safety hazards with nanomaterials, Some studies detected possible cancer-causing properties of carbon nanotubes, Some nanomaterials bounded with other materials or components (Jamie Jackson, CIS 121) II.1.5. RISK OF NANOTECHNOLOGY It is obvious to find out that except from the greatness and impressive opportunities that nanotechnology offers, the risks are associated with it as well. And these risk touch-up on Health, environment, Industryà ¢Ã¢â ¬Ã ¦ Because of the size of the particles, nanomaterials may enter human and other living bodies and disrupt body-functions. Some nanoparticles may also be non-biodegradable thereby posing a new threat to the environment. Therefore it is crucial to examine and estimate the risk for regulating the production, use, consumption and disposal of these materials. (Hyd and spook, 2012). For example, Health effects of several insulating materials are a concern; 1. The fibers released from fiberglass insulation may be carcinogenic, and fiberglass insulation now requires cancer warning labels. 2. There are also claims that the fire retardant chemicals or respirable particles in cellulose insulation may be hazardous (Dr. George, 2007). The risk most talked about is the ability of nanotech carbon tubes to potentially cause asbestosis-type illnesses, (Mike Childs, 2012) Manufactured nanomaterials (MNMs); and nanocomposites are being considered for various uses in the construction and related infrastructure industries. To achieve environmentally responsible nanotechnology in construction, it is important to consider the lifecycle impacts of MNMs on the health of construction workers and dwellers, as well as unintended environmental effects at all stages of manufacturing, construction, use, demolition, and disposal. Emphasis in industries; In India, late industry participation has also begun in this area, and there is an emphasis on fostering public-private partnerships (PPP). Nonetheless government support to this sector remains crucial for three reasons: 1. Nanotechnology is a capital-intensive technology and is in an embryonic phase, thus industry would not be able to sustain the research effort needed for the establishment of scientific and technological infrastructure. 2. The state is required to define the regulatory framework. In 2010-11 this process was initiated. 3. The state ,particularly in the developing country context, can set the agenda and resist the tendency to uncritically follow international trends in research that do not address their developmental needs.

III.1. Environmental application Environmentally, Nanotechnology also has the potential to help our environment. Example: It controls pollution through source reduction. This is a method of eliminating toxic waste at its source, with the understanding that releasing the waste into the environment is the last resort. Source reduction can be achieved by cleaning up existing processes or by reducing consumption of resources where such consumption creates pollution. III.1.1. Insulation The impact of the improvement of insulation reductions is counted by billions of pounds annually. Ref table (Fig06: Potential sources of EU CO2 emission reductions ) Nanoscale materials hold great promise as insulators because of their extremely high surface-to-volume ratio. This gives them the ability to trap still air within a material layer of minimal thickness (conventional insulating materials like fibreglass and polystyrene get their high insulating value less from the conductive properties of the materials themselves than from their ability to trap still air.) Insulating a nonmaterial may be sandwiched between rigid panels, applied as thin films, or painted on as coatings (Dr. George, 2007) Nanogel panels; Aerogel This material as an incredible ability and capacity such as strength, it can take its own load 2000 times reminding that it has only 5 percent solid and the rest is filled with air only an are also applicable on fabric architecture or structures. Because nanoporous aerogels can be sensitive to moisture, they are often marketed sandwiched between wall panels that repel moisture. Aerogel panels are available with up to 75 percent translucency, and their high air content means that a 9cm (3.5) thick aerogel panel can offer an R-value of R-28, a valu

McClelland and Maslow Theory Essay
Americanââ¬â¢s Psychologist David Clarence McClelland (1917-98) proposed that every individual have specific needs that can be classed into need for achievement (nAch), need for affiliation (nAff), and need for power (nPow). Regardless of gender, culture or age, human beings have three motivating drivers that will affect their behavior. People with a high need for achievement seek to excel, to accomplish in relation to a set of standards, to struggle to achieve success. High nAch individuals prefer work that has a moderate probability of success, ideally a 50% chance. There is a strong need for feedback as to monitor the progress of their achievements. They prefer either to work alone or with other high achievers. High achievers are not interested in rewards or money unless these rewards reflect a measurement of their success. Their desire is to do a task better than it has been done before. The individuals with high achievement needs are highly motivated by competing and challenging work. They also look for promotional opportunities in job. Second, the individuals who are motivated by affiliation have an urge for a friendly and supportive environment. They prefer to spend time creating and maintaining social relationships, enjoy being a part of groups, and have a desire to feel loved and accepted. Individuals with high nAff strive for friendships, prefer cooperative situations rather than competitive ones, and desire relationships involving a high degree of mutual understanding. Individuals having high affiliation needs prefer working in an environment providing greater personal interaction. Such people have a need to be on the good books of all. They generally cannot be good leaders. A high need for power may be expressed as ââ¬Å"personalized powerâ⬠or ââ¬Å"socialized powerâ⬠. Those with a high need for power work best when theyââ¬â¢re in charge. Because they enjoy competition, they do well with goal-oriented projects or tasks. They may also be very effective in negotiations or in situations in which another party must be convinced of an idea or goal. Those who need personal power want to direct others, and this need often is perceived as undesirable. Persons who need institutional power (also known as social power) want to organize the efforts of others to further the goals of the organization. Managers with a high need for institutional power tend to be more effective than those with a high need for personal power. McClellandââ¬â¢s theory of Needs allows for the shaping of a personââ¬â¢s needs; training programs can be used to modify oneââ¬â¢s need profile. The use of this information is to lead, praise, and motivate your team more effectively, and to better structure your teamââ¬â¢s roles. Maslow Theory In 1943 a Psychologist Mr. Abraham Harold Maslow suggested his Theory of Human Motivation. According to him, our actions are motivated in order achieve certain needs. This hierarchy suggests that people are motivated to fulfill basic needs before moving on to other, more advanced needs. The hierarchy of needs includes five motivational needs, often depicted as hierarchical levels within a pyramid. Maslow identified five types or sets of human need arranged in a hierarchy of their importance and priority. They are physiological, safety, love, and esteem and growth needs (self-actualization). Physiological needs are the basic needs for sustaining human life. These needs include food, shelter, clothing, rest, air, and water. These needs cannot be postponed for long. Unless and until these basic physiological needs are satisfied to the required extent, other needs do not motivate an employee. Second is safety, these include needs for safety and security. Security needs are important for survival, but they are not as demanding as the physiological needs. Examples of security needs include a desire for steady employment, health care, safe neighborhoods, and shelter from the environment. Next is social needs. An employee is a human being is rightly treated as a social animal. He desires to stay in group. He feels that he should belong to one or the other group and the member of the group should accept him with love and affection. He needs friends and interaction with his friends and superiors of the group such as fellow employees or superiors. After the first three needs have been satisfied, esteem needs becomes increasingly important. These include the need for things that reflect on self-esteem, personal worth, social recognition, and accomplishment. Lastly is self-actualization. Self-actualization is the desire to become what one is capable of becoming. It is a ââ¬Ëgrowthââ¬â¢ need. A worker must work efficiently if he is to be ultimately happy. Here, a person feels that he should accomplish something in his life. He wants to utilize his potentials to the maximum extent and desires to become what one is capable of becoming. Though everyone is capable of self-actualization, many do not reach this stage. This need is fully satisfied rarely.

Disneys Brands Success - 1371 Words
The Walt Disney Company has been successfully creating and capturing value for their customers for over nine decades. With a net worth of 74.9 billion dollars, Disney has claimed the title as of one of the most profitable companies in the world. Their product line is extensive, as they currently own and run a successful media network, several theme parks and resorts worldwide, an extensive merchandise line, a studio entertainment sector, as well as Disney Interactive. Disneyââ¬â¢s brandââ¬â¢s success hinders on several points of difference that have allowed the company to flourish. Firstly, Disney creates an undeniably unique experience for its customers. The theme parks have a ââ¬Å"magicalâ⬠feel to them, which keeps families coming back for decades.

Film, Medium Cool, By Haskell Wexler - 1424 Words
Despite women taking huge steps towards equality, the entertainment during the 1960ââ¬â¢s was still an awful representation. Many of the topics in my 1950ââ¬â¢s journals discussed the treatment of women in media during the fifties. I assumed as another decade passed, women would be portrayed more respectfully and accurately in many forms of entertainment. I assumed incorrectly. In a majority of what we analyzed, women were still treated like crap. Haskell Wexlerââ¬â¢s film, Medium Cool, follows a news cameraman named John Cassellis. This character makes women look like they are just there for men to walk on and completely disrespect. Not only did he seem to be in a relationship with over 3 women, he was extremely disrespectful to them as well. Johnâ⬠¦show more contentâ⬠¦In reality, the odds were stacked against the Americans from the start and some soldiers knew it wasnââ¬â¢t going to end well. The media, however, said the attack caused a lot of deaths, but it was a means to an end (Two Days In October). Some journalists found themselves at the forefront of the danger, giving their first hand experience to civilians. Overall, the Vietnam War set a new standard for a consistent stream of information. The current war in the Middle East, has been covered by many news outlets and reporters have been sent to interview and uncover some facts unknown by the general population. Also John F. Kennedy would not have won the election without the power of television. 1960 was the first year the presidential debates were televised. People who watched the debates said Kennedy won because he looked confident and his dark suit made him stick out more (The Century: Poisoned Dreams). Many who only listened to the debates said Nixon won due to his stronger points (The Century: Poisoned Dreams). Without television, the Civil Rights Movement would not have touched the lives of millions of Americans. The horrific images shown to the public, forced people to recognize how wrong civil rights protesters were treated in the South. Many of the protests discussed in the documentary series, Eyes on the Prize, were captured on film. In No Easy Walk, the civil rights movement targeted Birmingham,
