Robert Fulton essays

Robert Fulton essays Robert Fulton is not a name that children hear often like George Washington or Abraham Lincoln. But with his invention, Fulton changed the way people get around. He made the first steamboat. With the help of a friend, Fulton changed history forever. Robert Fulton was born on November 14, 1765 in Lancaster County, Pa. Fulton was born to an Irish immigrant family. For six years, Fulton lived on an unproductive farm until the farm lost its mortgage in 1771. After they lost the farm, the Fultons moved to Lancaster. Fultons father died in 1774. Since Fulton learned to read and write at home, he was sent to a Quaker school when he was eight. A few years later, Fulton became an apprentice at a jewelry shop in Philadelphia. He specialized in painting pictures on ivory for lockets. After settling his mother on a small farm, Fulton want to Bath, VA to recover from a bad cough. The people in Bath admired Fultons paintings. They suggested he study in Europe. When going back to Pennsylvania, Fulton looked for someone to sponsor him so he could go to London. He found a person that wanted more culture in the town and sponsored his passage to London. When he was in London, people showed little interest towards his work. While in London, he got to know the idea of propelling boats. Then in 1794, Fulton admitted that he was not a painter. His new interest was canal engineering. In 1796, Fulton proposed the Treatise of Improvement of Canal Navigation. That treatise consisted of small canals extending through the countryside. Instead of locks, Fulton also included details on inclined planes to raise boats. Only a few parts of his idea was excepted in the British Isles and no where else. Since the war between Britain and France was going on, Fulton had an idea to improve fighting. Fulton went to Paris and proposed the idea of a submarine named the Nautilus. In Fultons idea, the Fren...

A Killers Mind.

A Killers Mind. Before we can discuss what serial killers do, we must first define what a serial killer is. Some people might place serial killers into the same group as mass murderers. This would be incorrect because they are two totally different types of killers. While both of these individuals may kill many people, the difference lays in the reason they kill and the period over which they kill their victims. An event or a build up of circumstance triggers mass murderers and causes them to act. This may be the result of a stressful situation or frustration either at work or in their private lives. For whatever reason, they may choose to use a weapon and kill people that they feel are responsible for their problems. They may also kill total strangers in a bid to get even with whomever or whatever they feel wronged them. Whatever their reason, they are usually cooperative and quite often docile if they survive the episode.Mugshot of David Berkowitz. Copyright 2003 New Yor...It seems that this one-t ime outburst of violence, once enacted, puts an end to any future events of this type for that individual. While the mass killer may kill many people in one attack, when the attack is over, their mission is complete. The mass killer's victims may not be chosen for any other reason than being in the wrong place at the wrong time.Serial killers are a totally different and more dangerous threat to society. They may not kill many people at one time, but they may kill for many years without being detected. They are able to kill again and again without being caught because they are careful in their choices of victims. They typically pick victims who are vulnerable and un-able to defend themselves such as children, the elderly or women. They also pick victims...

Ability to communicate in French along with English will help an individual in accessing employment opportunities in areas where French and English is used professionally to communicate. An individual who has the ability to communicate in French along with English can gain access to the top universities throughout the world. A total of 41 universities where education is delivered in French language are amongst the top 250 universities throughout the world. One such university includes Ecole Polytechnique ParisTech University (Top Universities, 2015). Individuals who know how to communicate in French can easily gain admission in such universities. Learning French can help an individual learn about the cultures of different groups and regions. Broady states that there are more than 200 million individuals who speak French language and they are divided in five different continents (Broady, 2003, p.200). One can take advantage of having the ability to communicate in French to learn about the culture of these individuals. Two languages that can be considered as global languages includes French as well as English but one needs to learn French along with English to reap the various benefits that the French language has to offer. By learning French one can increase the number of employment opportunities they can access. An individual can gain access to top universities throughout the world by learning French and they can learn about the cultures of 200 million individuals throughout the world with this

Supervision Platform Essay Example | Topics and Well Written Essays - 2500 words

Supervision Platform - Essay Example Thus, as a supervisor I intend on ensuring that via collaborative efforts between the teachers and other academic staff, each student gets the maximum level of emotional satisfaction possible. The aim is not to produce money making machines in the long-run, in fact to create a lot of highly motivated individuals with the potential to change the world for the better tomorrow. Thus, the supervisory practices which I aim at adopting constitute a collaborative paradigm where every contributor will also be decision maker adding value to the educational practices being employed. Mission Statement as a Supervisor As a supervisor I aim at empowering the teachers as they are directly involved in the personal as well as the professional development of a child. According to a research published in the New York Times by Fretty, Friedman and Jonah (2012), the educational practices adopted by the primary school teachers directly impacts the professional development of the child, i.e. if the qualit y of a primary school education is enhanced by 1%, the earning rate of the resultant student also increases by 1%. This implies that the quality of teachers needs to be enhanced by persistent training and evaluation, also by transforming the way strategies are designed. When the teachers will directly be involved in the decision-making process, an innate capacity for moral responsibility will follow, thus I aim at developing a collaborative working environment giving way to creativity and innovation. My Role as a Supervisor As a supervisor, I am bound to take multiple roles which are even subject to be extended in the long run. I consider my professional as well as my moral responsibility to understand the needs and desires of the teachers as well as the students, and to sync these needs with the modern day practices to impart quality education. Considering this scenario, it is my sole responsibility to transform the teaching patterns by adding new and updated courses to the curricu lum to ensure the progression of the students to the most advanced levels possible. In addition, I intend on taking up this role to add value to the skills and creativity of the students by introducing additional courses relevant to arts. The video illustration; â€Å"connecting with the arts: A workshop for Middle-Grades Students† stresses on the significance of combining arts subjects with sciences to create a sense of innovation in the minds of the students (Education Next). Also, the addition of new courses to the curriculum would naturally demand skills development for the teachers to cope up with the transformation, thus skill development would also become an important role in the process. By initiating discussions with the teachers, it will be my responsibility to create opportunities for the teachers to acquire new skills to equip them with the necessary teaching tools and techniques. In this context, as a supervisor my role won`t be limited to the evaluation and moni toring of the current practices, but also initiating new ones whenever the need arise. Evaluations and collaborative practices go hand in hand, being an important role as the supervisor under the systematic procedures. Leadership Orientation The most traditional leadership styles have been the

How surface area of vanes effect Essay Example for Free

How surface area of vanes effect Essay Hypothesis I predict that by increasing the surface area of the vanes on the wind vane, I will increase the air resistance therefore slowing the rate at which the weight will drop. Primary Work If a piece of paper and a marble are in free fall, they will fall at the same speed, so they should hit the ground at the same time. If you test this by just dropping a marble and a piece of paper you will find it is not true. This is because the objects are not in free fall. To be in free fall, gravity has to be the only force acting on the objects. When you just drop something, there is also air resistance. Air resistance is a type of fluid friction. Because friction acts in the opposite direction of the objects motion, air resistance of an object falling downward is an upward force. This is because a falling object is coming down, so the opposite direction is up. If air resistance were equal for every object, objects would still fall at the same rate. Since we know they do not fall at the same rate, we know air resistance is different for different objects. The amount of air resistance acting on an object depends on the objects surface area. If an object has a small surface area, it will have little air resistance. Because the piece of paper has a larger surface area than the marble, the marble will have less air resistance than the piece of paper and the paper will fall slower. This is what I expect to happen with a wind vane. As the wind vane turns, air resistance will act on each of the separate vanes. By increasing the surface area of the vanes, I will increase the air resistance therefore making the rate at which the weight drops slower, because there is more opposing force. Theory Newtons law of gravity and Galileos freefall theory state that objects of any mass will fall to the ground at the same time if in a complete vacuum i. e. space, if not in a complete vacuum i. e. earth, they will fall at different times because of air resistance (and weight). The air resistance depends on the surface area of the object, the larger the surface area, the more amount of air resistance. In the case of a wind vane, the objects dropping are the separate vanes. Plan Of Experiment I will drop a 15g weight from a piece of string; this string will be attached to an axel which is further attached to a wind vane. Firstly the string will be coiled around the axel then when let go, the weight will drop and the wind vane will turn to create opposing force. I will time the rate at which it falls. My dependant factor will be the time the weight takes to hit the table. My independent factor will be the surface area of the vanes. To ensure a fair test, my controls will be the distance from the table and the weight of the falling object. Apparatus   Stand Clamp 20g Weight 55cm of String   Axel   Cork With Equal Slits For Vanes   Card For Vanes   Stopwatch Method 1. I will set up the equipment as shown below. 2. I will cut out 6 vanes with a certain surface area and put them into their corresponding slits in the cork. 3. I will coil the string attached to the weight around the axel and then drop it. I will time the time it takes for the weight to hit the table and record my results. 4. I will repeat the experiment for accuracy of results Results Surface Area (cm) 1st Try (secs) 2nd Try (secs) Average (2. d. p) 3 1. 8 1. 6 1. 7 4 2. 4 2. 3 2. 35 5 3. 2 3. 4 3. 3 6 3. 9 3. 7 3. 8 7 4. 4 4. 3 4. 35 8 4. 7 4. 5 4. 6 9 5. 4 5. 7 5. 55 10 6. 3 6. 5 6. 4 Graph Of Averages = Line Of Best Fit Conclusion I have found that I was right in my hypothesis in thinking that the larger the surface area of the vanes on a wind vane, the more time it takes for a weight attached to it by means of an axel to fall. This was because, as stated in my theory and primary work, the surface area increased the amount of air resistance and this force opposed gravity which was pulling the weight down, therefore making it travel slower. This is shown in my graph as a positive correlation. Evaluation I had no major anomalous results, this was down to accurate measuring and because I kept my experiment fair. After doing this experiment I would like to be able to calculate the actual amount of air resistance created by a wind vane and see if there is any relationship between surface area and amount of air resistance.

Batteries :: essays research papers

BATTERIES There are many kinds of batteries which consist of different materials in order to produce an electric charge. Here are some of the most common batteries, what they consist of and how they work. Bichromate Cell (see picture # 1) A battery is a device which converts chemical energy into electrical energy. A battery usually consists of two or more cells connected in series or parallel, you can also have a single cell battery. All cells consist of a positive electrode, and a negative electrode. An electrolyte is a liquid substance capable of conducting electricity. In this substance one of the electrodes will react producing electrons, while the other will except electrons. When the electrodes are connected to a device to be powered, called a load, an electrical current flows. Batteries where the chemicals cannot be returned to their original form once the energy has been converted (that is, batteries that have been discharged) are called primary cells or voltaic cells. Batteries in which the chemicals can be returned to its original form by passing an electric current through them in the direction opposite that of normal cell operation are called secondary cells, rechargeable cells, storage cells, or accumulators. Dry Cell Battery(see picture # 2) This is the most common battery that people use today like Energizer or Duracle batteries. The most common form of a primary cell is the Leclanche cell, invented by a French chemist Georges Leclanche in the 1860s. The electrolyte for this battery consisted of a mixture of ammonium chloride and zinc chloride made into a paste. The negative electrode is zinc, and is the outside shell of the cell, and the positive electrode is a carbon rod that runs through the center of the cell. This rod is surrounded by a mixture of carbon and manganese dioxide. This battery produces about 1.5 volts. Another widely used primary cell is the zinc-mercuric-oxide cell, more commonly called a mercury battery. It can be made in the shape of a small flat disk and is used in this form in hearing aids, and electric wristwatches. The negative electrode consists of zinc, the positive electrode is of mercuric oxide, and the electrolyte is a solution of potassium hydroxide. The mercury battery produces about 1.34 volts. The fuel cell is another type of primary cell. It is unique in that the chemicals aren't contained within the cell but are supplied from outside of the cell.

AIDS & progres

Although progress has been in treating HIV infection and AIDS, the epidemic remains a critical public health issue in all communities across the country and around the world.Prevention, early detection, and ongoing treatment remain important aspects of care for people with HIV infections and AIDS.Nurses in all settings encounter people with this disease; thus, nurses need an understanding of the disorder, knowledge of the physical and psychological consequences associated with the diagnosis, and expert assessment and clinical management skills to provide optimal care for people with HIV infection and AIDS.In 1987, just 6 years after the first cases of AIDS were reported, the U.S. Food and Drug Administration (FDA) approved the first antiretroviral agent; in 1988nthe first randomized controlled trial of primary prophylaxis of Pneumocystis carinii pneumonia appeared in the literature; and in 1995 protease inhibitors joined the growing number of antiretroviral agents.Improved treatment of HIV and AIDS has resulted in increased survival times; in 1996, 1997, and 1998, age-adjusted death rates fell 29%, 48%, and 21%, respectively.II. BackgroundSince acquired immunodeficiency syndrome (AIDS) was first recognized more than 20 years ago, remarkable progress has been made in improving the quality and duration of life of persons with HIV infection.During the first decade, this progress was associated with recognition of opportunistic disease processes, more effective therapy for complications, and introduction of prophylaxis against common opportunistic infections (OIs).The second decade has witnessed progress in developing highly active antiretroviral therapies (HAART) as well as continuing progress in treating OIs (Letvin, Bloom & Hoffman, 2001).Since the HIV serologic test (enzyme immunoassay [EIA], formerly enzyme-linked immunosorbent assay [ALISHA], became available in 1984, allowing early diagnosis of the infection before onset of symptoms, HIV infection has been b est managed as a chronic disease   and most appropriately managed in an outpatient care setting (Gallant, 2001).A. EpidemiologyIn fall 1982, the Centers for Disease Control and Prevention (CDC) issued a case definition of AIDS after the first 100 cases were reported. Since then, the CDC has revised the case definition a number of times (1985, 1987, and 1993).All 50 states, the District of Columbia, U.S. dependencies and possessions, and independent nations in free association with the United States report AIDS cases to the CDC using a uniform surveillance case definition and case report from (CDC, 2002).Starting in the late 1990s, more states started to implement HIV case reporting in response to the changing epidemic and the need for information on persons with HIV infection who have not developed AIDS.As of December 2001, there were 816,149 reported cases of HIV/AIDS and 506, 154 adults, adolescents, and children in the United States (including U.S. dependencies, possession, and associated nations) living with AIDS. Unprotected sex and sharing of injection drug use equipment are the major means of transmission of HIV.A total of 43, 158 AIDS cases were diagnosed in 2001. For men diagnosed with AIDS during 2001, 59% were in the exposure category of men who have sex with men; 24% in injection drug use; and 7% in heterosexual contact.In women diagnosed with AIDS during that same period, 44% reported injection drug use and 52% reported heterosexual contact. Comparing race/ethnicity amount the three largest groups diagnosed in 2001, 20,752 were black, not Hispanics (CDC, 2002).The number of people living with AIDS is not evenly distributed throughout the United States. States with the largest number of reported AIDS cases during 2001 were New York (7,476), Florida (5,138), California (4,315), Texas (2,892), and Maryland (1,860) (CDC, 2002).AIDS has reached epidemic proportions in some other parts of the world. According to the Joint United Nations Program on HIV /AIDS, more than 18.3 million people worldwide have died of AIDS and 34.3 million people are infected with HIV, with 5.4 million people newly infected with HIV in 1999 alone (Letvin, Bloom & Hoffman, 2001).UNAIDS (2001) reports that since the epidemic began, more than 60 million people have been infected with the virus, making it the most devastating disease ever.The earliest confirmed case of HIV infection was found in blood drawn from an African man in 1959 (Stephenson, 2003). Although factors associated with the spread of HIV in Africa in the 1960s; however, social changes such as easier access to transportation, increasing population density, and more frequent sexual contacts may have been more important (Stephenson 2003).III. DiscussionA. SymptomsTreatment of specific manifestations of HIV infection and AIDS in the person with advanced disease targets symptoms. Patients with HIV/AIDS experience a number of symptoms related to the disease as well as the effects of treatment. Som e of the vivid symptoms are as follows:Respiratory Manifestation. Shortness of breath, dyspnea (labored breathing), cough, chest pain, and fever associated with various OIs, such as those caused by Pneumocystis carinii, Mycobacterium avium-intracellulare, CMV, and Legionella species.The most common infection in people with AIDS is Pneumocystis carinii pneumonia (PCP), one of the first OIs described in association with AIDS.PCP. PCP is the most common OIs resulting in an AIDS diagnosis. Without prophylactic therapy, PCP will develop in 80% of all HIV-infected individuals. P. carinii was originally classified as a protozoan; however, studies and analysis of its ribosomal RNA structure suggest that it is a fungus.Its structure and antimicrobial sensitivity are very different from other disease-causing fungi. P. carinii causes disease only in immunocompromised hosts, invading and proliferating within the pulmonary alveoli with resultant consolidation of the pulmonary parenchyma.
