Superconductors & physicist Essay Example for Free

Superconductors physicist Essay Superconductivity was discovered by a Dutch physicist Kammerlingh Onnes in 1911 while studying â€Å"resistivity of mercury at low temperature† (Halliday 1999). To his surprise he found that below a temperature of about 4K mercury suddenly lost all its resistivity that was named by him as a superconductor. Conductors are those substances through which electricity pass to a larger extent. Superconductors are conductors that lose their resistance at a very low temperature. Every conductor possesses resistivity up to a certain extent whereas; superconductors lose their resistivity at low temperature. Superconductors are conductors with zero resistance. Functions and Applications Nowadays superconductors are used by scientists in making different things like noise reduction filters, communication satellites, mobile signal receivers, and other sophisticated and important machines which are extremely useful to us. Extensive researches are being carried out to design superconductors and ceramics to be used future for communication technology (Klauda 2000). Several experiments are conducted to reveal the possibility of cryogenic and high-temperature superconductor technology for use in base transceiver stations (BTS’s) and communication satellites for global mobile communication (Klauda 2000). Super conductors has helped a lot in the medical field by saving and diagnosing a lot of disorders in the human body like introducing MRI(magnetic resonance imaging) in which image is made of the inner delicate parts of the human body such as brain, stomach etc (Uses for Superconductors). Super conductors have also played a major role in advancing the transport system by replacing the huge electromagnets with super conducting magnets thus making it faster. A train operating on super conducting magnet attained an unbelievable speed of 361 mph (Uses for Superconductors). Electric generators composed of super conductors are of great importance because they are much better than the ordinary and typical generators. Super conducting generators produce much more electricity than ordinary generators. Nowadays efforts are made to commercialize these generators in order to fulfill the energy need of the world. Nowadays superconducting transformers have also been introduced to the world. In some countries underground cables including copper are replaced by superconductors making it more efficient than ordinary copper cables. Modern calculations reveal that supper conducting cables are 7000% efficient than ordinary copper cables (Uses for Superconductors). It is believed that in the next decade superconductors will replace electrical appliances in which copper is used. Super conductors are also used in industry to make Ultra high performance filters. Future of Superconductors Superconductors are of high utility in the future. Beside benefits there are also some drawbacks of using superconductors on a larger scale. Superconducting magnets are hazardous to human health thus restricting the commercial usage of MAGLEV vehicles (Uses for Superconductors). Another hitch in the wide usage of superconductivity is its high cost that for several decades restricted the functions of superconductors. Since superconductivity is attainable only at a very low temperature that is achieved in a bath of liquid helium. Since helium is found in very little quantity in the atmosphere is therefore, extremely costly limiting the functionality. After decades of hectic research, liquid nitrogen has replaced helium lowering the cost to a greater extent. References Halliday, David. (1999).

“Psychosis and delusional states and their relationship with normal ano

According the fourth edition diagnostic manual of mental disorders (American Psychiatric Association, 2000), the category psychotic disorders (Psychosis) include Schizophrenia, paranoid (Delusional), disorganized, catatonic, undifferentiated, residual type. Other clinical types include Schizoaffective Disorder, Bipolar Affective Disorder/Manic depression, mania, Psychotic depression, delusional (paranoid) disorders. These are mental disorders in which the thoughts, affective response or ability to recognize reality, and ability to communicate and relate to others are sufficiently impaired to interfere grossly with the capacity to deal with reality; the classical and general characteristics of psychosis are impaired reality testing, hallucinations, delusions, and illusions. Mostly, these are used as defining features of psychosis even if there are other psychotic symptoms that characterise these disorders (L. Bortolotti, 2009). Delusion and hallucination in their different forms are the major symptom of psychotic disorders. There is a growing evidence however that these symptoms are not exclusively pathological in nature. The evidences show that both delusion and hallucination occur in a variety of forms in the general population. This paper presents and analyzes the relationship between the above major psychotic symptoms with normal anomalous experiences that resembles these symptoms in the normal population. Delusions are a symptom of psychiatric disorders such as dementia and schizophrenia, and they also characterize delusional disorders. Delusion is defined as a false belief based on incorrect inference about external reality that is firmly sustained despite what almost everyone else believes and despite what constitut... ...inds of individuals join such organizations, and can they be differentiated from people diagnosed with a psychotic disorder (Bhugra, 1996)?† These results support previous findings on two levels. First, they support the notion that there is a continuity of function between normality and psychosis, with `normal’ individuals (both non-religious and religious) being at one end of the continuum, the deluded individuals at the other extreme, and members of NRMs at the intersection. Indeed, even this classification is over-simplified, as is illustrated by the overlapping range of scores between the four groups. Second, it confirms the multidimensionality of delusional beliefs, since the NRMs and the deluded groups could be differentiated by their scores on the Distress and Preoccupation dimensions, but not on the Conviction dimension (McKenna and Orbach, 1999).

Fingerprint Analysis

I chose two glasses for this project. I chose a tall, green stained glass and then a short clear glass. I washed my hands thoroughly before attempting the project, and scrubbed my sink. I then put my fingerprints all over both glasses. I filled my sink with cold water, and then submerged my two glasses into the water for 4 hours. I took the glasses out, and saw that the fingerprints were still on the glasses!! I was extremely shocked at this finding because, I surely though that the water would eliminate the fingerprints. Hot water- I filled up a sink full of hot clean water, and sat both glasses in the sink for 4 hours, I drained the water and checked the glasses. There was STILL fingerprints on the glasses!!! I am in shock, once again! I surely thought since the cold water didn’t remove the fingerprints, that the hot water would remove the fingerprints. Soapy Water- I filled up a sink full of soapy water, and placed the two glasses into the sink and left them over night. After cooking breakfast, I checked on the glasses. I drained the water and carefully took the glasses out by the bottom so I wouldn’t get fingerprints on the glass. I examined the stained glass first, I did not see any fingerprints visually! However, when I examined the small clear glass I saw two fingerprints left on the glass. But most of the others have disappeared. So now, I am leaving new fingerprints all over the glass to do the last activity. Salt Water- After placing the two glasses into the salt water for 5 hours I examined them, and they both still had fingerprints all over the glasses. Now, I would like to test this again with more salt in the future to see if I use more salt, would it eliminate the prints.

How Much Does Xarelto Cost 4 Money-Saving Tips

How Much Does Xarelto Cost 4 Money-Saving Tips SAT / ACT Prep Online Guides and Tips If you have atrial fibrillation or a high risk of deep vein thrombosis (DVT), blood clots, and/or strokes, your doctor might prescribe you Xarelto. A novel oral anticoagulant (NOAC), or blood thinner, Xarelto works by keeping dangerous blood clots from forming. But how much does Xarelto cost? Read on to learn about the Xarelto price for those who do and don’t have health insurance. In addition, we'll explain how this cost changes depending on the pharmacy you visit, show you how to find a Xarelto coupon, and compare the Xarelto cost with those of other similar drugs. How Much Does Xarelto Cost? Without insurance, the typical Xarelto price is more than $400 for 30 tablets, or around $15 per pill. That said, it's possible to get Xarelto at a far cheaper rate. How much Xarelto costs for you depends on two main factors, which we'll discuss in more detail below: Your health insurance The pharmacy you go to Health Insurance Most health insurance plans, including Medicare, at least partly cover the cost of Xarelto. According to the official Xarelto website, â€Å"more than 90% of people with prescription coverage and on Medicare are covered for Xarelto at the lowest branded copay cost.† In other words, if your insurance covers Xarelto, you’ll only need to pay the lowest co-pay for brand-name drugs for your insurance plan. This means you'll likely pay around $10-$50 for your Xarelto prescription, or slightly more than whatever your co-pay is for generic drugs. If you’re on Medicare, you can get an estimate for your Xarelto co-pay through the website GoodRx, which offers a convenient Xarelto cost calculator. If you have a prescription deductible, be aware that you must meet this amount before you can pay your co-pay for Xarelto. So if you haven't met your deductible, you'll likely end up paying the full cost of Xarelto (that is, more than $400 for a bottle of 30 pills). There are a couple of things to note, though. For one, there are currently no generic alternatives to Xarelto (generics are usually cheaper than name-brand drugs). Thus, you won't be able to find an identical drug at a cheaper price. The other thing to note is that dosage doesn’t generally affect the cost of Xarelto. According to Drugs.com (as well as the table below, which we'll look at shortly), you’ll usually pay the same price for a 10-mg pill as you would for a 15- or 20-mg pill. A 15-mg Xarelto pill. Pharmacy The second major factor that affects Xarelto cost is the pharmacy you go to. The following table shows estimated out-of-pocket costs for Xarelto. These are the prices you’d pay at different pharmacies if you didn’t have insurance or if your insurance didn’t cover Xarelto. All estimates for pharmacies (except for Costco) are based on the price listings at GoodRx. Note: The â€Å"- † indicates that estimates are unavailable for that dosage of Xarelto. However, you can generally assume that the prices for all dosages will be close to the same. Pharmacy Dosage Price for 30 Tablets Price per Tablet Costco 10 mg $438.74 $14.62 15 mg $438.74 $14.62 20 mg $438.74 $14.62 CVS 10 mg $481 $16.03 15 mg $484 $16.13 20 mg $473 $15.77 Kroger 10 mg $466 $15.53 15 mg $466 $15.53 20 mg $466 $15.53 Meijer 10 mg - - 15 mg - - 20 mg $446 $14.87 Rite Aid 10 mg - - 15 mg $5 $17.03 20 mg $5 $17.03 Safeway 10 mg $527 $17.57 15 mg - - 20 mg $531 $17.70 Target 10 mg - - 15 mg - - 20 mg $471 $15.70 Walgreens 10 mg $495 $16.50 15 mg $507 $16.90 20 mg $477 $15.90 As you can see, there isn’t a whole lot of difference among Xarelto prices at various pharmacies. Most of the time, you’ll pay anywhere in the range of $440-$530 for a bottle of 30 pills, with Costco offering some of the lowest prices, and Safeway and Rite Aid offering some of the highest. Another feature to note is that dosage doesn’t usually change pharmacy costs, or at least not by more than $10-$30. How to Get a Xarelto Coupon or Discount There are a few ways you can get large Xarelto discounts, many of which are through the official Xarelto website. If you have commercial health insurance (not Medicare or Medicaid) with prescription coverage, you can sign up for the Janssen CarePath Savings Program Card. This card gets you a $0 co-pay on your Xarelto prescription each month, making it entirely free for you! Alternatively, if you have Medicare, Medicaid, commercial insurance, or no insurance at all, you might be eligible for an up-to-30-day free trial of Xarelto. Finally, if you don’t have prescription coverage for Xarelto, the official Xarelto website recommends getting in contact with the Johnson Johnson Patient Assistance Foundation (JJPAF) to see if you qualify for financial assistance. In addition to the official website, tons of coupon and medical websites offer Xarelto discounts. You can search for these on Google by typing in â€Å"Xarelto coupon† or â€Å"Xarelto discount.† Note, however, that many coupons cannot be used with health insurance. One solid website is Drugs.com, which offers a savings card you can use at most pharmacies to get discounted rates on your Xarelto prescription. GoodRx is another good resource, with free coupons knocking off up to $100 on a bottle of Xarelto. How Does the Xarelto Cost Compare With Other Drugs? According to the official Xarelto website, â€Å"Xarelto has the lowest out-of-pocket cost than any other blood thinner in its class in the U.S.† This means that, compared to other anticoagulants in the same class as Xarelto- i.e., factor Xa inhibitors- Xarelto should be more affordable. Other factor Xa inhibitors include Eliquis and Savaysa. Here is a quick look at how these three medications compare with one another in regard to cost: Drug Name What GoodRx Says What Drugs.com Says* Eliquis $482.69 for 60 5-mg tablets $413.44 for 60 5-mg tablets Savaysa $380.05 for 30 60-mg tablets $336.23 for 30 60-mg tablets Xarelto $480.09 for 30 20-mg tablets $413.09 for 30 20-mg tablets *All prices are based on the Drugs.com discount card. In this chart, we’ve compared the estimated prices of the most common dosages and quantities of these three similar anticoagulant medications. But because there are wide ranges in cost, quantity, and dosage for these drugs, it's difficult to determine which is the cheapest. Ultimately, it's best to consult your doctor or pharmacist to see which medication will be most affordable for you based on your insurance. Recap: What Is the Cost of Xarelto? The cost of Xarelto, a prescription blood thinner, ultimately depends on whether your health insurance covers the drug and which pharmacy you go to. Since most insurance plans cover Xarelto, your co-pay should normally cost around $10-50 (assuming you’ve already met your prescription deductible, if you have one). If your insurance doesn’t cover Xarelto or if you don’t have insurance, you’ll need to pay the full price, which is anywhere from $440 to $530 for a one-month supply. Most pharmacies charge similar fees for Xarelto. Costco offers some of the lowest prices at around $440, while Safeway and Rite Aid offer some of the highest prices above $500. Many discounts for Xarelto are available online and through the manufacturer. One discount, available on the official Xarelto website, works with your insurance to give you a $0 co-pay each month. It's difficult to compare the cost of Xarelto to those of other similar medications such as Eliquis and Savaysa due to differences in dosage, quantity, and pharmacy. Therefore, talk with your doctor or pharmacist if you want more information about which medication will be most affordable for you.

Vought F4U Corsair in World War II

Vought F4U Corsair in World War II The Chance Vought F4U Corsair was a noted American fighter that debuted during World War II. Though intended for use aboard aircraft carriers, the F4U experienced early landing issues that initially prevented its deployment to the fleet. As a result, it first entered combat in large numbers with the U.S. Marine Corps. A highly-effective fighter, the F4U posted an impressive kill ratio against Japanese aircraft and also fulfilled a ground-attack role. The Corsair was retained after the conflict and saw extensive service during the Korean War. Though retired from American service in the 1950s, the aircraft remained in use around the world until the late 1960s. Design Development In February 1938, the U.S. Navy Bureau of Aeronautics began seeking proposals for new carrier-based fighter aircraft. Issuing requests for proposals for both single-engine and twin-engine aircraft, they required the former be capable of a high top speed, but have a stall speed of 70 mph. Among those who entered the competition was Chance Vought. Led by Rex Beisel and Igor Sikorsky, the design team at Chance Vought created an aircraft centered on the Pratt Whitney R-2800 Double Wasp engine. To maximize the power of the engine, they selected the large (13 ft. 4 in.) Hamilton Standard Hydromatic propeller. While this significantly enhanced performance, it presented problems in designing other elements of the aircraft such as the landing gear. Due to the propellers size, the landing gear struts were unusually long which required the aircrafts wings to be redesigned. In seeking a solution, the designers ultimately settled on utilizing an inverted gull wing. Though this type of structure was more difficult to construct, it minimized drag and allowed for air intakes to be installed on the leading edges of the wings. Pleased with Chance Voughts progress, the U.S. Navy signed a contract for a prototype in June 1938. Chance Vought XF4U-1 Corsair prototype during tests at the National Advisory Committee for Aeronautics (NACA), Langley Research Center at Hampton, VA, in 1940-41.   NASA Langley Research Center Designated the XF4U-1 Corsair, the new aircraft quickly moved forward with the Navy approving the mock-up in February 1939, and the first prototype took flight on May 29, 1940. On October 1, the XF4U-1 made a trial flight from Stratford, CT to Hartford, CT averaging 405 mph and becoming the first US fighter to break the 400 mph barrier. While the Navy and the design team at Chance Vought were pleased with the planes performance, control issues persisted. Many of these were dealt with by the addition of a small spoiler on the leading edge of the starboard wing. With the outbreak of World War II in Europe, the Navy altered its requirements and asked that the aircrafts armament be enhanced. Chance Vought complied by equipping the XF4U-1 with six .50 cal. machine guns mounted in the wings. This addition forced the removal of fuel tanks from the wings and an expansion of the fuselage tank. As a result, the XF4U-1s cockpit was moved 36 inches aft. The movement of the cockpit, coupled with the aircrafts long nose, made it difficult to land for inexperienced pilots. With many of the Corsairs problems eliminated, the aircraft moved into production in mid-1942.

Operational History In September 1942, new issues arose with the Corsair when it underwent carrier qualification trials. Already a difficult aircraft to land, numerous problems were found with its main landing gear, tail wheel, and tailhook. As the Navy also had the F6F Hellcat coming into service, the decision was made to release the Corsair to the U.S. Marine Corps until the deck landing problems could be resolved. First arriving in the Southwest Pacific in late 1942, the Corsair appeared in larger numbers over the Solomons in early 1943. Marine pilots quickly took to the new aircraft as its speed and power gave it a decisive advantage over the Japanese A6M Zero. Made famous by pilots such as Major Gregory Pappy Boyington (VMF-214), the F4U soon began to rack up impressive kill numbers against the Japanese. The fighter was largely restricted to the Marines until September 1943, when the Navy began flying it in larger numbers. It was not until April 1944, that the F4U was fully certified for carrier operations. As Allied forces pushed through the Pacific the Corsair joined the Hellcat in protecting US ships from kamikaze attacks. F4U Corsair attacks Japanese ground targets on Okinawa, 1945. National Archives and Records Administration In addition to service as a fighter, the F4U saw extensive use as a fighter-bomber providing vital ground support to Allied troops. Capable of carrying bombs, rockets, and glide bombs, the Corsair earned the name Whistling Death from the Japanese due to sound it made when diving to attack ground targets. By the end of the war, Corsairs were credited with 2,140 Japanese aircraft against losses of 189 F4Us for an impressive kill ratio of 11:1. During the conflict F4Us flew 64,051 sorties of which only 15% were from carriers. The aircraft also saw service with other Allied air arms. Later Use Retained after the war, the Corsair returned to combat in 1950, with the outbreak of fighting in Korea. During the early days of the conflict, the Corsair engaged North Korean Yak-9 fighters, however with the introduction of the jet-powered MiG-15, the F4U was shifted to a purely ground support role. Flown throughout the war, special purpose-built AU-1 Corsairs were constructed for use by the Marines. Retired after the Korean War, the Corsair remained in service with other countries for several years. The last known combat missions flown by the aircraft were during the 1969 El Salvador-Honduras Football War.

Che Guevara Essay Example | Topics and Well Written Essays - 500 words

Che Guevara - Essay Example Revolution is a struggle and plea for freedom. Men such as Che Guevara throughout history have fought as well as triumphed and lost revolutions that shaped our lives now. The battle has been very inhuman and many soldiers shed blood and lost their lives in these battles. War and the revolution have this implication of having to use force and power over those who are weak and oppressed. To describe a specific type of creative production created by human, it is called Art. Che made use of art in order to revolt against the tyranny of the existing administration. Aesthetic value is a characteristic of every artwork. There should be a sense of beauty and pleasantness with the product of the human. Art has several purposes. It can be for human expression, a part of a ritual or to symbolize a feeling or idea. The definition of art can be vague and it cannot be limited by a specific meaning. Human creativity is the main driving force of art. Some people may think that art is just a piece of work that has no significant purpose but to fill our aesthetic needs.
