Essay --

The Great Depression was an economic problem in North America, Europe, and other industrialized countries around the world that began in 1929 and lasted until 1939. It was the longest and most stressing depression ever. The U.S. economy had gone into a depression six months earlier, but the Great Depression had begun with a breakdown of stock-market prices on the New York Stock Exchange in October 1929. The next three years stock prices in the United States had continued to drop, until 1932 it had dropped to about 20% of its value. Other than messing up thousands of individual investors, the decline in the value of good banks and other financial facilities went bad. Many banks were constantly forced to hide their debts, and that’s why by 1933, 11,000 of the United States 25,000 banks had failed. The failure of so many banks was because of the lack of confidence the economy had, which had led to too much reduced of spending and demanding money. This was constantly dropping, and unemployment began rising. By 1932, U.S. manufacturing had dropped to 54% of its money, and unemployment had gone up to between 12 and 15 million workers. The Great Depression began in the United States, but then had turned into a worldwide economic problem. The United States was trying to come out from the depression as the main one in the depression. National economies had been weakened by the depression itself, but by war debts in Germany and other defeated nations to. So once the American economy had dropped and the money of American investments to Europe was gone, the depression had become worst than nations that were mostly in debt to the United States, Germany and Great Britain.

Vietnam Economy

nom Economic Vietnam has during the last two decades developed into a dynamic and fast growing market – also in automobile industry. Economic reforms, membership of WTO since 2007 and an impressive number of foreign investments, the notable increase in GDP, in people’s demand for high quality product and the almost-zero of the domestic automobile industry have led Vietnam to become the potential market for Volkswagen. The global crisis led to a temporary slowdown of Vietnam’s fast economic growth, but growth is back on track with 6. % growth in 2010 and more than 7% per year expected in 2011-2015. Table 1: Vietnam’ GDP real growth rate (%) [pic] Source: Source: General Statistics Office of Vietnam The rate of economic growth has during the last decade amounted to 7-9% per year, amongst the highest recorded growth rates in the world. The GDP per capita is USD 1160 (2010), and an increasing number of Vietnam’s 87 million inhabitants demand consumer pr oducts of higher quality. Table 2: Vietnam’s GDP per capital (US$) [pic] Source: General Statistics Office of Vietnam However, the average income in Vietnam is still fairly low in comparison with the company price (about†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.. cai nay lay so lieu ben product nhe, to k tim duoc). According to â€Å"Background note of Vietnam† recorded by U. S Department of State in http://www. state. gov, Vietnam’s per capita income in 2010 was just $1,168 one person per year. Whereas, imported cars in Vietnam have to suffer upto 3 kinds of duty, including: Import Duty, Extra Duty, and Value Added Tax. Regardless of how strict Vietnam taxation policy is, the accession agreement which was compulsory for Vietnam to become WTO’s member in 2007 obliged Vietnam to lower its import tariffs and to welcome foreign investments in most commercial sectors of the economy. Certain sectors are partly protected against foreign competition in an interim period, but from 2012 respectively 2014 all sectors of the economy must welcome foreign goods and services as well as investors on an equal footing with local companies and investors. Therefore, we totally hope that in the upcoming period, such a 200% tariff for exported cars will not exist. Vietnam automobile market is not that big but it sees a potential signal. According to General Statistics Office of Vietnam [ http://www. gso. gov. vn/default. aspx? tabid=393&idmid=3&ItemID=11605 to k biet trich nguon ntn cho dung voi Harvard form ca T_T], the demand for imported cars, especially types of fewer than 9 seats which makes of approximately 70% in total, keeps increasing remarkably, from 21279 units in 2005 to 51059 in 2008 and reach the number of about 80410 in the last year. Whereas the domestic automobile industry seems to not improve at all. Until now, the domestic company still can not produce even one car. Vietnam  now has 10 automobile JVs including one 100 % foreign-owned enterprise (GM Daewoo), one domestic manufacturer (Truong Hai). The manufacturers make vehicles of 17 world brands: Fiat, Sangyong, PMC, Mazda, Kia, Chevrolet, Daewoo, Mitsubishi, Mercedes Benz, Suzuki,  Toyota, Isuzu, Ford, Hino, Hyundai (trucks, bus), Chery and Honda. In this moment, Volkswagen is one of more then 10 brands having distribution channel in. These brands include BMW (Euro Auto), Audi, Porsche (PSC), Hyundai (Thanh Cong), Lifan (Bao Toan), Chrysler (IC Auto), Subaru (MIV), Dong Feng,  Ã‚  MAN (VMC) and Fiat – Alfa Romeo (Mekong Auto), who are all considerable competitors. It is a great opportunity for the company to dominate Vietnam market but also a challenge when our products are almost kind of high quality with high price.

Biological Importance of Water

The Biological Importance Of Water Water plays a huge role in our lives, the molecule which is comprised of two atoms of hydrogen and one atom of oxygen bonded together has many complex properties. The molecule maintains a bent shape due to its tetrahedral arrangement and the negative lone pair of electrons on the oxygen. The electrons from both hydrogen and oxygen are joined covalently but the difference in electronegativity lets the electrons from hydrogen get pulled slightly toward the oxygen therefore making the hydrogen positive and the oxygen negative (a dipole molecule). Hence water being a polar molecule, the result of this lets water get attracted to other polar molecules and more importantly to other water molecules. Hydrogen bonds form in-between these polar molecules. The many unique properties water withholds will be discussed in this essay varying from its thermal properties to its solvent properties. The polar molecule attracts other polar water molecules. The slightly negative oxygen is attracted to the slightly positive hydrogen. Weak hydrogen bonds connect them. Electrons are pulled closer to oxygen making oxygen negative and hydrogen positive and therefore polarised. Solvent properties Since water is polarized it attracts ions and other polarized molecules. Water can collect around the molecule separate it making the chemicals able to move freely around and react with other chemicals. For example when NaCl enters water they dissociate into ions (Na+) and (Cl-), this occurs because both ions are more attracted to water dipoles. The water molecules surround the ions therefore making it hydrated, the molecules are bound providing a osmotic surface. This process takes place withen animals and plants. In order for a plant to abssorb minerals from the soil and for the blood(waterbased) to transport glucose, amino acids and minerals. Without this soloution living orgasisms wouldn’t be able to physical survie due to lack of nutrients. All metablic reactions happen in this soloution, such a respiration, excretion and photosythesis. In the circumstance that a molecules intermoleculer bonds are to strong the charged surface normally gets attracted to water which would then remain isolated, this therefore avoids them joining – collodical suspension. The plasma in your blood is a example of a collodical suspension as it carries all the nurtirents and elctrolytes but doesn’t fuse with the red blood cells. Thermal properties A realtively large proportion of energy is needed to increase the tempreture of water (high heat capacity) because of the large amounts of hydrogen bonds water pocesses. The more water content there is the harder it is to change the tempreture. Due to the high water content inside our bodies changing tempreture is a slow process, making maintaing a stable body tempreture easy, water acts as a buffer. This is obviously a advantage so enzymes can work at there optium tempreture. When sweating occurs a lot of heat energy escapes via evaperation making it a good cooling mechanism and helping organisms mantian the optium body tempreture which is vital to endothermic organisms. Density and freezing properties When water is solid , its less dense then it was when it was in liquid form. Ice floats because it is about 9% less dense than liquid water. The density of water starts to decrease after 4 celsus and therefore starts to float, insulating water particals below it. As water cools below 4Â °C, the hydrogen bonds adjust to hold the negatively charged oxygen atoms apart. This produces a crystal lattice. If it wasn’t for density being less dense water would sink and the whole ocean would freeze killing water life and reducing the circulate nutrients in oceans. When water freezes is expands inorder to make space for more hydrogen bonds. Water stays liquid through a large tempreture range which helps water animals live. High surface tension and cohesion Since water moves together in long unbroken columns through plants (xylem tissue)- the low viscosity allows water to drift easily. Transpiration steam occurs in soloution and is held together by cohesion. Water molecules attach to the xylem vessel showing the use of adhesion(because both water and cellulose are polar molecules there is a strong attraction for water within the hollow capillaries of the xylem). The guard cell is turgid because it has an increase in turgor pressure – water enters the central vacuole by osmosis. The cohesion of water molecules creates a large surface tenison ontop of the water letting small organisms use it as a habitat. Water also effects the support of mammals due to the waterfilled tissue which boosts are skeletal support. All of these properties show that water has great biological importance and is fundamentally vital for any living organisms to survive.

The Role of Sleep in Learning and Memory.

Students tend to overload themselves by overnight study to memorize all the study material. However, most of them do not realize that we will have a better result by an adequate sleep than having a three hour sleep before an exam to memorize all the material. This restless lifestyle will significantly reduce health level and in fact reduces our memory consolidation and opportunity to use our unconscious mind to improve the skill that we learn. This theory was first introduced by Muller and Pilzecker about 100 years ago.They made a hypothesis that memory consolidation is time dependent and require regulating from our brain cell which leads to further development in memory consolidation theory nowadays. (McGaugn, 2000. ) According to â€Å"Neurology board review: An illustrated study guide. † written by Professor Mowzoon, sleep is divided into 2 main types, which is non-rapid eye movement (NREM) and rapid eye movement (REM). NREM sleep occur seventy five percent of our sleep and REM sleep only occur for twenty five percent of our sleep. NREM sleep can divide into 4 stages. Stage 1 happens when we are between being awake and asleep.Stage 2 occurs at the beginning of sleep; brain will produce periodic brain wave activity known as sleep spindles that can relax our body muscle and heart rate. Stage 3 and 4 take place in deep sleep. In these stages, our body tissue cultivates and repairs. Lastly, stage 5 of the sleep is involved in REM sleep where most dreaming occurs. In REM sleep, brain and other parts of our body becomes more active but muscles remain in a lessen state. (Mowzoon, 2007) A journal article â€Å"Sleep dependent memory consolidation† from Nature precisely categorizes sleep stages and memory.There are several type of memories but commonly they are divided into declarative memories which we can recall in our mind and non-declarative memory where normally used without conscious. The term memory consolidation is referring to memory stabilizat ion, where memories become more resistible to interference. Several studies show that certain memories are consolidation through REM sleep as complex cognitive procedural learning take place. Procedural memory and spatial memory are greatly improved in REM sleep, where both these memories help to recording information and how to get things done.Motor skills like dancing, would advance while we are in REM sleep. Positron emission tomography (PET) brain imaging has demonstrated that the night after training, region that is active during task performance is reactivated during REM sleep. Besides, even event related potentials shows that high temporal resolution of brain processing in the period of REM sleep. (Stickgold, 2005)The result shows that REM sleep and memory consolidation are highly positive correlated, as a REM-rich periods person will be 3 times more likely to improve in certain skill than a sleep deprivation person.Endogenously, Nature NeuroScience did an electrophysiologica l reading between hippocampus and neocortex respond to episodic and semantic memories. Episodic memory is memories that involve emotion, while semantic memory refers to factual information and knowledge. Both of these memories are categorized in declaration memory. In the experiment, a group of people were given some task and simulating the learning multiple times. After that, subjects are given 2 detail fMRI scan that one is scheduled directly after the learning session and another scan 48hours later.The result shows that there is an increase in functional connectivity over time between hippocampus and medical prefrontal cortex in the first scan is lower than second scan. Subject remember more detailed and perform better after a good night sleep. Therefore learning is highly influence by the successively of reactivation between hippocampal and prefrontal network during our sleeping cycle. (Peyrache, 2009) In addition, the journal of Science written by Maquet, show that sleep has be en occupied that plastic cerebral change due to fresh memory and learning.The recurrence of neuronal bonds during sleep is proven by a few experiments. The neural activity is further shown in walking behavior seems to be reestablished during sleep. The reactivation will increase the intercellular connection strength between the element of network and incorporation of the new experience into long term memory. (Maquet, 2001) Both of this experiment proven that REM sleep has great effect to memory consolidation and learning. Exogenously, sleep is also illustrated to be obliging in memory consolidation and learning.Practice is not the only way to attainment all skill, performance could be improve between learning period and not within it. Explicit skill where we learn it intentionally is sleep-dependent. From an experiment from journal of Current Biology, offline skill improvement can only observed within 12 hours including sleep. The result show that implicit skill might improve due to time but explicit skill is positive correlated to sleep. When we are fully conscious of learning a new thing, the improvement of skill without practice is totally reliant on sleep. Robertson, 2004) Moreover, BBC news reported that in United Kingdom, a group of adult was given a task and for the group who were sent to sleep did better than those who carried on without sleep. Dr Matthew Walker mentions that â€Å"Sleep not only rights the wrong of prolonged wakefulness, but at neurocognitive level, it moves you beyond where you were before you took a nap†. This supplementary enhances the theory that, sleep will improve memory consolidation and learning. (BBC, 2010)As a college student, I fully understand that weighty academic course loads leads to sleep deprivation, but a good sleeping cycle will helps to boost up our academic result. Even though sleep helps to improve our academic, we still have to put in the same effort in our daily life to maintain and improve our result.Re ferences: Mowzoon, N. , M. D. , Flemming, K. , D.

The use of a SINGLE literary device (characters) in the novel the Essay

The use of a SINGLE literary device (characters) in the novel the great gatsby by fitzgerald - Essay Example To convey the vapidity of the American Dream, Fitzgerald presents them as the type of people likely to use others and put wealth and superficial qualities above all else. With specific emphasis on descriptive phrases, the corruption of money, and valueless relationships, this essay traces Fitzgerald’s use of characterization to achieve this aim. Fitzgerald makes excellent use of descriptive phrases and subtle character elements to demonstrate the underlining vapidity of the characters’ existences. Haupt indicates descriptive phrases used to convey this superficial lifestyle. â€Å"Bootlegged gin, cigarettes placed into mouths following the clicking shut of their golden cases, gowns, suits, chauffeurs. Games, double meanings, illicit affairs, fortunes made in mysterious ways, drinking to drown an awkward moment or the quiet disappointment of your life† (para. 1). Even from the novel’s beginning epitaph, the reader understands that money and its importance is always on Gatsby’s mind: That â€Å"gold hat† includes Gatsby’s decision to change his name, Jimmy Gatz, to one that will assure him success in life. He doesn’t like his real name as representative of the old Jimmy and believes he must sacrifice truth [his name] in order to create a more positive image, one that exudes success and â€Å"self assurance† (Bloom 75). It is a superficial adjustment, since a name is only that and it is what a person does that matters, or should matter to anyone who meets him, whether in business or socially. The name change, in another sense, represents part of the gold hat he must wear to achieve success and Daisy’s love. The use of the words [gold hat] in the epigraph clearly indicates that someone [Gatsby] is telling himself to use the glitter of material deception in order to win a girl despite advise from Nick later in the story that â€Å"You can’t repeat the past† (Fitzgerald, The Great Gatsby, 116). â€Å"This is precisely what Gatsby

Project Essay Example | Topics and Well Written Essays - 1000 words

Project - Essay Example It is also important to note that some motors produce immense output power, but cannot be efficient enough. It is under such conditions that people make use of H Bridge in the efficient control of the Motors’ direction. Project Fundamentals An H-bridge circuit refers to a power circuit that is electric, and used in the control of electric motors like DC motors used in automotive applications. The H-bridge functions in controlling the direction and speed of the motor by allowing a limited amount of current to flow in the motor through the right direction (Barrett, 2012). It is made up of four MOSFETs, which are under the control of control signals of the (PWM) Pulse Width Modulation. The original design of the DC motor control incorporates Multisim LabVIEW co-simulation that permits the performance of the entire system to be authenticated on the desktop. The motor has such parameters as inductance, the load weight, and armature resistance for accurate verification of the result s of the performance. The use of a multisim-labVIEW co-simulation ensures that one shall not have to digital and analog systems separately. During the implementation stage of the model, the circuitry of the analog can be transferred for photocopying to the Ultiboard. Such a transition between the Ultiboard and Multisim makes sure that there is a precise convey of simulated designs. The graphical code of control is moved to a Single Board Rio 9695 target. This is usually an acquisition device and an embedded control that puts together a FPGA that is user-reconfigurable, a real time processor, and input or output of printed circuit board. The four MOSFETs needed in designing a H-bridge can be demonstrated with the diagram below. Two of the MOSEFETs should be of P channel (IRF9540N), while the other two should be of N channel (IRF540N). They should be designed in such a way that the motor’s rotation is controlled through an on-off-on switch. The motor’s closed-loop contro l starts through inputs that are user-defined such as the necessary step size and speed. This message is resent to the Multisim design through the co-simulation terminals. Negotiations between labVIEW and Muiltisim occur as a guarantee in conversation and accuracy for both sides. In case of abrupt drops or peaks in Multisim, negotiation in time-step allows Multisim to alter the available time-step to view the drops and peaks. A point by point model between digital systems and analog circuits results to an advanced system both in accuracy and behavior. Once the verification of the system design has been made with Multisim and labVIEW co-simulation, the complete circuit can be moved to Ultiboard for routing and layout. List of Components The list of components used in the circuit includes: MOSFET P Channel (IRF9540N) – 2 MOSFET N Channel (IRF540N) – 2 Motor – DC 6 volts Battery – 9 volts Switch – 1 Connecting Wires and Strip Board Controlling the Mot or The control of the motor is done through the two ways switch connected to Q1 and Q3 of the circuit. If a signal is sent to Q1the motor is stimulated to move in a forward direction, while on the other hand, if a signal is sent to q3 the motor is stimulated run in a reverse direction. It is never possible to sent signals to both Q1 and Q3at the same time because of the use of on off on switch. This can be summarized using the following table: Q1 Q3 Stop 0

Motivation Profiles Essay Example | Topics and Well Written Essays - 1250 words

Motivation Profiles - Essay Example Maslow (In Huit, 2004) refers to these needs as physiological. Ella's needs may also include safety or security or the need to be out of danger, but it is not necessarily so. She has not strived very much to the higher levels of education but just enough to get her a job. She is contented to be paid enough for her family's daily needs for food and shelter. As her family's needs grow, she finds that she has to move for promotion which she looks at in terms of bigger take home pay, but not necessarily bigger responsibility. The fight for promotion is tight at Ella's workplace. To be promoted, she resorts to giving gifts to her supervisor or persons having to do with promotion in her place of work. Like her, she thinks people primarily find satisfaction in material gain and she may find favor from her superiors. Ella is submissive to authority and represses her own impulses. In fact, her own idea of a boss is authoritarian. The hostile boss is not a problem to her if she receives a promotion (bigger pay). She is willing to forego much personal freedom in favor of a promotion that would assure her of food and shelter every month. She defers from Marcelo and Masoko in that her needs are very basic - just of the existence level described by Alderfer (1972). Marcelo Marcelo's needs may be said to occupy the two second higher level needs described in Maslow's hierarchy: belongingness and love, and esteem needs (See Huit, 2004). Marcelo is therefore expected to easily affiliate with others and be accepted. At the same time, he sees the drive to achieve at his level, be competent, gain approval and attain recognition. There is a strong need to be liked which may not be good in terms of decision-making (See McClelland, 1987). Status is a prime motivator to Marcelo. There is greater personal satisfaction in receiving praise or recognition with Marcelo and a promotion would realize these things for him. (See McClelland, 1987). Marcelo believes that promotions are given in exchange for something given, not necessarily hard work. It is a give and take situation. So he tries to praise his supervisors, do as he is ordered without any complain that he may be liked. In exchange for pleasing his boss, he believes he is working for promotion. For all his investments in gaining approval and at the same time being affiliative with his supervisor, he expects that promotion is in store. Marcelo has been toeing every rule given in his workplace, conscious that every broken rule requires a punishment and farther away from attaining a promotion. Therefore, he keeps quiet and never questions whatever policies he disagrees with. His needs, however, are higher than that of Ella's. He needs affirmation and affiliation over and above mere biological needs. Marcelo may be said to be other-oriented in that his work life involves relationships with significant others. He is satisfied by mutually sharing thoughts and feelings, and that acceptance, confirmation, understanding, and influence are elements important to him (Alderfer, 1972). Masoko Masoko sees more freedom in thinking than Ella and Marcelo. His actions are governed by the interplay of possible
