On finishing her chores, she would warm herself in one of the corners of the chimney and thus her sisters called her Cinderella. Then the two sisters got invited to a ball at the palace in honor of the Prince. They left her behind. As she wept for being left behind, her godmother came and magically showed her how to go to the palace. She also dressed Cinderella magnificently. After reach ing the palace, the prince invited her to the next ball in which Cinderella lost her glass slipper. The prince vowed to marry the girl who could wear the slipper and it emerged that Cinderella was the only one. She was thus married by the Prince (â€Å"Cinderella†, n.d., p. 1†). Characters The characters in this story include, the main character, Cinderella whose mother dies and she is left with her father. Cinderella is depicted as a good girl. The next character is Cinderella’s step mother; depicted as ill-tempered. She has two daughters who are shown as proud and as ill-tempered as their mother. There is also Cinderella’s godmother who is shown as a good woman, others include: Lord High Chamberlain, heralds, six mice, a rat and six lizards. The mice, rat and lizards were used magically by Cinderella’s godmother to escort Cinderella to the palace (â€Å"Cinderella†, n.d., p. 1†). Theme The theme of the story is the importance of human values. Cinderella is very good to her stepmother even after mistreatment. She is also good to her stepsisters even when they despise her. Her goodness pays off when, in the end, she is the only one who can marry the Prince. She is adored for that and her stepsisters apologize to her. The stepsisters would like to marry the Prince but they miss the chance. This story, therefore, highlights the importance of good temperament and human values (â€Å"Cinderella†, n.d., p. 1†). Plot The story begins with the birth of Cinderella which is followed by the death of her mother. Then her father remarries an ill-tempered woman with two daughters of Cinderella’s age with the same disposition. Cinderella is given hard chores but she does not complain.Advertising Looking for essay on literature languages? Let's see if we can help you!

How maglev trains work

How maglev trains work Introduction Maglev trains or magnetic levitation trains were opened up for commercial transport in 1984 when they operated between Birmingham airport and the main railway. Britain was the first country to develop these trains, although other countries developed their sns and used them to transport mainly people.Advertising We will write a custom essay sample on How maglev trains work specifically for you for only $16.05 $11/page Learn More Maglev trains are based on the principle of electromagnetism to be levitated and propelled. The car has no contact with the rail, an advantage that affords them to move without friction, and therefore move at very high speeds of almost 500 kilometers per hour. The cars have no engines or any moving parts, though they need a lot of electricity to create the desired powerful electromagnets on the tracks. The basic principle that is applied in maglev trains is that of the magnetic like poles which repel while opposites attra ct. Working principle of maglev trains The trains have attached magnets that are very powerful to create a high density of magnetic field at the bottom. The tracks have electromagnetic magnetic field that repels this magnetic density on the bottom, and thus the car is propelled forward. These are the U-shaped guide way that has individual coils to which an alternating current is applied in order to create repulsion between magnets. It is the force that is created to achieve both goals, to propel the car and levite it vertically at the same time. The gap between the train and the trucks is about 2 and 3 cm for Indatruck models, or 1 cm for Transrapid Internatioanal model. Meissner effect is used to create bearings without the train coming into contact with the trucks. Thus, the train can climb steep hills or even ice-covered trucks without losing speed considerably. Efficiency is thus increased in this technology, although these trains tend to quite pricey compared to conventional tr ains (Blundell, 2009). Other developments introduced another set of coils in which alternating current passes to create electromagnets. Two sets of coils achieved the function of checking the lateral movement, while the other levitated the car. This is done by placing guidance magnets on the left side so that the train moves forward and does not hit the sides. â€Å"Transrapid international† or Electromagnetic Suspension (EMS) To create large magnetic fields, superconductors are used to produce stronger magnetic fields, although it was noted that these strong magnetic fields are produced by rare earth magnets, other than iron and ferrite. Neodymium-iron-boron is used to create the desired high magnetic field. The material used must be thick, have low resistivity and possess the ability to change fields quite fast. According to the author, the train is propelled forward after it is levitated by the repulsion of magnetic forces. The truck has several coils which use alternating current to change polarity at a high frequency. The change of polarity by the coils makes them propel forward. Vertical magnetic forces that provide levitation make the car to balance in suspension and is stabilized by the horizontal magnetic forces so that the car is centered and does not drift to any side.Advertising Looking for essay on natural sciences?

Get your first paper with 15% OFF Learn More According to Gibilisco (2006), such an arrangement requires the acceleration and braking to be provided by linear motors and additional electromagnets to be in place in the track. Higher levitation speeds were achieved in the Japanese models by positioning upper and lower coils, such that they created field currents of figure of eight. This arrangement is called Halbach array whose main purpose is concentration of magnetic field above the car. While the lower coils produced repulsive forces for levitating the train, the lower coils provided the â€Å"push-pull effect† together with linear motors in the tracks which propel the car forward at higher. Indutrack models The train has other features that make it to be safe, given that some can reach high speeds of 522 km/h. Electric power is used to accelerate the train until full levitation is reached. The reason to use the superconductors, besides the high magnetic field potential, is that they can retain this field for some time even after power have failed. Power can fail, and modern maglev trains have auxiliary wheels that help them decelerate until they stop. Source: hk-phy.org/energy/transport/trans_phy/images/ems_maglev.gif Computers are used to monitor levitation distance to ensure the speeds and movements are safe so that in case of any anomaly, the train is automatically halted and corrective actions are taken. Some models have batteries for electricity back up in case power supply is interrupted. Conclusion There is really little difference bet ween the models of producing motion in the maglev trains, although depending on the arrangement of electromagnetic coils and force that is used to provide first acceleration, top speeds attainable can vary. For example, maglev trains that are based on Electrodynamic Suspension (EDS) use rubber wheels for the first 100 km/h after which coils are activated and move by levitation propulsion after which they can reach top speeds of 522 km/h.Advertising We will write a custom essay sample on How maglev trains work specifically for you for only $16.05 $11/page Learn More List of References Gibilisco, S.

Cervical Cancer and the Human Papilloma Virus Essay

Cervical Cancer and the Human Papilloma Virus - Essay Example Most of these cancers stem from infection with the human papillomavirus, although other host factors affect neoplastic progression following initial infection. Compared with other gynecologic malignancies, cervical cancer develops in a younger population of women. Thus, screening for this neoplasia with Pap smear sampling typically begins in adolescence or young adulthood. Most early cancers are asymptomatic, whereas symptoms of advancing cervical cancer may include bleeding, watery discharge, and signs associated with venous, lymphatic, neural, or ureteral compression. Diagnosis of cervical cancer usually follows colposcopic examination and histologic evaluation of cervical biopsies. Worldwide, cervical cancer is common, and ranks second among all malignancies for women (Parkin, 2005). In 2002, an estimated 493,000 new cases were identified globally and 274,000 deaths were recorded. In general, higher incidences are found in developing countries, and these countries contribute 83 percent of reported cases annually. Economically advantaged countries have significantly lower cervical cancer rates, and add only 3.6 percent of new cancers. This incidence disparity highlights successes achieved by cervical cancer screening programs in which Papanicolaou (Pap) smears are regularly obtained. There is considerable variation of incidences, screening, diagnosis, and treatment statistics throughout the world, but the trend of the disease is considered to be resulting mainly from financial and cultural characteristics affecting access to screening and treatment. The age at which cervical cancer develops is in general earlier than that of other gynecologic malignancies, and the median age at diagnosis ranges from 40 to 59 years. In women aged 20 to 39 years, cervical cancer is the second leading cause of cancer deaths. There are data that indicate the cervical cancer is a preventable disease, and in developed countries, such as, in the United States, where well established screening programmes exist, it is estimated that 30% of cervical cancer cases will occur in women who have never had a Pap test. In developing countries, this percentage approaches 60%. It is a matter to be reckoned that in spite of these statistics, the worldwide incidence of invasive disease is decreasing, and cervical cancer is being diagnosed earlier, leading to better survival rates. Worldwide data indicate that the mean age for cervical cancer is 47 years, and the distribution of cases is bimodal, with peaks at 35 to 39 years and 60 to 64 years of age. Risk Factors There are numerous risk factors for cervical cancer: young age at first intercourse (
