Narcolepsy Essay -- Disorder Sleep Sleepy Health Essays

Narcolepsy Lethargy, regardless of whether because of rest apnea, overwhelming wheezing, idiopathic hypersomnolence, narcolepsy or a sleeping disorder from any number of rest related scatters, compromises a huge number of Americans' wellbeing and financial security (1). Maybe to some degree most worried of these scatters are those that permit rest without having any power over when it happens-idiopathic hypersomnolence and narcolepsy. The two are firmly related in that both reason people to nod off without such control, yet narcolepsy happens with no dreaming during rests (2). For a considerable length of time, narcoleptic individuals have been nodding off in corners, worried, as they have given various endeavors to attempt to remain engaged and conscious. Be that as it may, other than the inordinate exhaustion that individuals experience, there most likely should be more that can be related with causing such tiredness among individuals at an uncontrolled level. There may particularly not be an explanation including the I-capacity of the cerebrum, as individuals don't know about when essentially they will fall into their profound rest. Narcolepsy has been clinically characterized as a ceaseless neurological issue that includes the body's focal sensory system (CNS). The CNS is fundamentally similar to a parkway of nerves that conveys messages from the mind to different pieces of the body. Along these lines, for individuals with narcolepsy, the messages about when to rest and when to be conscious some of the time hit barriers or reroutes and show up in an unlucky spot. This is the reason somebody who has narcolepsy, not oversaw by meds, may nod off while having supper or occupied with social exercises or even now and again when they are so centered around being wakeful, yet they can't be because of their narcoleptic nature. Much of the time, be that as it may, conclusion... ...r individual sorrow.

Ancient Chinese secret, eh

Ancient Chinese secret, eh On this otherwise lovely three-day weekend, my suitemate Jeremy 09 found himself stricken with a case of influenza, exhibiting such symptoms as nasal congestion, a sore throat, and a mild fever. So, he called up a friend from high school, who happens to be a pre-med (DING!) at Harvard (DING!) who recommended the ancient Chinese secret (double DING!) of dissolving salt in hot water to make a solution strong enough to taste, then snorting said solution up your nose. Fortunately, prior to subjecting himself to this remedy, Jeremy came to me to ask if it had any scientific merit from the perspective of a chemical engineer. Well, if you snort a salt solution up your nose, I guess, by osmosis, the cells of your nose should lose water to the higher-concentration salt solution, which might then dissolve whatevers blocking your nose. Apparently this was a satisfactory explanation for Jeremy: Imagine what happens to the foul cocktail of snot, mucus and salty water goes after it passes through your nose. Better yet, dont. Although Jeremy did say that his nasal passages were instantly cleared after this treatment, its still something Im not too anxious to try anytime soon. Still, its better than Mitras proposed cure for the same ailment, which she forced upon our other suitemate Gabe 08, also suffering from terrible congestion.

Bare Knuckles Boxing

For much of the 19th century boxing was not considered a legitimate sport in America. It was generally outlawed as a notorious crime, and boxing matches would be raided by the police and the participants arrested. Despite the official prohibitions against boxing matches, boxers often met in celebrated fights which drew large crowds and were openly reported in newspapers. And in the era before padded gloves became standard gear, the action in the bare-knuckle era was particularly brutal. Did You Know? Boxing was generally illegal in 19th century America, with fights held in secret locations.Bare-knuckle bouts were brutal, and could last for hours.Fighters could become famous, and some, peculiarly, picked up a political following.One bare-knuckles champion went on to serve in Congress. Despite the fame of some boxers, matches often tended to be scraps organized by neighborhood political bosses or outright gangsters. The fights could go on for hours, with opponents battering away at each other until one collapsed or was beaten insensible. While the contests involved punching, the action bore scant resemblance to modern boxing matches. The nature of the fighters was also different. As boxing was generally outlawed, there were no professional fighters. The pugilists tended to be otherwise employed. For instance, one noted bare-knuckles fighter in New York City, Bill Poole, was by trade a butcher, and was widely known as Bill the Butcher. (His life was very loosely adapted and portrayed in the Martin Scorsese film Gangs of New York.) Despite the notoriety and underground nature of bare knuckles fighting, some participants not only became famous, but were widely respected. Bill the Butcher, became a leader of the Know-Nothing Party in New York City before being assassinated. His funeral drew thousands of mourners, and was the largest public gathering in New York City until Abraham Lincolns funeral in April 1865. A perennial rival of Poole, John Morrissey, regularly found work as an election-day enforcer for New York City political factions. With what he earned boxing he opened saloons and gambling joints. His pugilistic reputation helped Morrissey to eventually be elected to Congress, representing a New York City district. John Morrissey during his bare knuckles boxing career. Library of Congress While serving on Capitol Hill, Morrissey became a popular figure. Visitors to Congress often wanted to meet the man known as Old Smoke, a nickname he picked up in a saloon fight when an opponent backed him up against a coal stove and set his clothes on fire. Morrissey, incidentally, proved he had enormous tolerance for pain when he won that particular fight. Later in the 19th century, when the boxer John L. Sullivan became popular, boxing became somewhat more legitimate. Still, the air of menace continued to surround boxing, and  major bouts were often held in peculiarly remote locations designed to skirt local laws. And publications like the Police Gazette, which focused on boxing events, seemed happy to make boxing seem shady. The London Rules Most boxing matches of the early 1800s were conducted under the London Rules, which were based on a set of rules laid down by an English boxer, Jack Broughton, in 1743. The basic premise of the Broughton Rules, and the subsequent London Prize Ring Rules, were that a round in a fight would last until a man went down. And there was a 30-second rest period between each round. Following the rest period, each fighter would have eight seconds to come to what was known as the scratch line in the middle of the ring. The fight would end when one of the fighters could not stand, or could not make it to the scratch line. Theoretically there was no limit to the number of rounds fought, so fights could go on for dozens of rounds. And because the fighters punched with bare hands, they could break their own hands by attempting knock-out punches to their opponents heads. So matches tended to be long battles of endurance. Marquess of Queensberry Rules A change in rules occurred in the 1860s in England. An aristocrat and sportsman, John Douglas, who held the title of the Marquess of Queensberry, developed a set of rules based on the use of padded gloves. The new rules came into use in the United States in the 1880s.

Determination Of Solubility Of Polar Solutes - 1074 Words

Introduction In the extraction of certain compounds, solubility plays an important factor in how the procedure is performed. The identification of which solvent is best for the substance is crucial. The relation of polarity between the solute and solvent is determined at a molecular level. The relationship between the solvent and solute needed shared similar characteristics. Polar solutes are dissolved in polar solvents while nonpolar solutes are dissolved in nonpolar solvents. From a chemical level, molecules are attracted to other similar molecules closest to their properties. Polar molecules are only attracted to polar molecules in both the solute and the solvent, and the same goes for nonpolar molecules. This explanation†¦show more content†¦For example, in some alkaline solvents acidic products will become deprotonated, keeping them soluble in water. The target compound can then be extracted as a free base. The extract results then are isolated by the addition of two immiscible sol vents. Two solvents that cannot be mixed are used so that there is a clear separation between the aqueous and organic layer. The component needed for extraction is contained in the organic layer. This is because the compound is more soluble to the composition of the organic layer. Multiple extractions with smaller volumes are more efficient than a single extraction at a one large volume. When an organic solvent is used to extract a compound from the aqueous solvent, smaller volumes will result in a better extraction. The success upon the collection of the crude material is depended on how well the water is absorbed by the anhydrous drying material. The presence of the drying material correlates with the vapor pressure of the other compound. When the vapor pressure is low, there is a smaller amount of moisture in the gas produced. Once the anhydrous material is added and clumping was avoided, the evaporation of the added organic substance can proceed. The final material collected can be physically identified by the final color of the precipitate. A greenish- white precipitate is most likely identified to be pure, and a brownish color indicates that the collected material is wet, and notShow MoreRelatedThin Layer Chromatography Lab Report1791 Words   |  8 Pagesmolecules, and determines the identity of a mixture of compounds.

Permanent Establishment Free Essays

The concept of permanent establishment (PE) in tax jurisdiction is changing as a result of digital innovations in international business. For a country like Nigeria, permanent establishment allows the country to tax the income or profit of foreign companies with a fixed place or physical presence in the country for 183 days or 12 months. But digital businesses do not need a fixed place or maintain a physical presence in the country before they can make a profit. We will write a custom essay sample on Permanent Establishment or any similar topic only for you Order Now They do not necessarily need to have an office, a factory, or a workshop in Nigeria before generating a stable income from the country. Examples of digital businesses that make income from Nigeria include GoDaddy.Com, Amazon.Com, Ebay.Com, etc. These companies do not have a fixed place of operation in Nigeria but generate income through digital presence in the country. This puts to test the concept of a permanent establishment in Nigerian tax jurisdiction. To understand the nature of permanent establishment in a digital economy, there is a need to investigate taxation jurisdiction on digital business from the angle of a developing country such as Nigeria. This study will be guided by the following objectives:Examine the principle of permanent establishment as expounded in the United Nations (UN) and Organisation for Economic Co-operation and Development (OECD) Model;Discuss the impact of digital business on the concept of a permanent establishment? Explore the possibility for a source state, such as Nigeria, to tax incomes generated by web platforms (i.e. Google or Facebook);Identify and discuss the challenges faced by the Nigerian government in getting taxes from companies who operate in the digital economy;Use the new definition of a permanent establishment in Italy to analyze tax jurisdiction on digital business in Nigeria.
