What Is Convection Essays - Meteorology, Continuum Mechanics

What Is Convection ? Convection is the heat transfer in a gas or liquid by the circulation of currents from one region to another or convection can also be defined as a flu i d motion caused by an external force of gravity. Convection is heat transfer by circulating currents of air as in 'THERMALS' in the atmosphere. Heated air has a lower density than cool air and therefore rises. Cooler air moves in below the rising warm air and circulatory currents are set up. Thermals are used by Hang-gliders and Para-gliders to gain lift. Convection is also used in space heating as in the home. Radiation is due to rays of direct heat as from the sun or an open fire . It is the phys ical movement of warm air (or other fluid) into an area of cooler air (or other fluid). Normally the movement is vertical as the horizontal movement is called advection. Significant evidence can be found in many places in the natural world. The first one that comes to mind is the development of cumulonimbus clouds. Warm, moist air flow upwards because it is more buoyant than the surrounding air. As it moves upwards it cools as it expands and eventually forms clouds. Another example would be the convective cells found in hot springs. The hot water is less dense and rises, sometimes quite vigorously, producing a lot of turbulence at the surface.

Im late for school, and my mother had to walk me in to class so that my teacher would know the reason for my tardiness. My mom opens the door to my class room, and there is a hush of silence. Everyones eyes are fixed on my mother and me. She tells the teacher why I was late, gives me a kiss goodbye and leaves for work. As I sit down at my seat, all of my so-called friends start to call me names and tease me. The students tease me not because I was late, but because my mother is white. Situations like this are hard for a young child to deal with. These type of situations are what bi-racial children deal with every day. The term bi-racial means a childs heritage is made up of two cultures or ethnic groups. In this paper I will compare the advantages and disadvantages of having dual heritage. I will also tell about the most often misconstrued problems the public perceives about a bi-racial child, with black and white heritage. These children encounter issues such as: Grasping self concept or identity and acceptance of their personal appearance. Dual heritage is most often looked at as different, good or bad. Sometimes people having dual heritage are seen as outcasts of society. These are just small things that have to do with having dual heritage. One advantage of having both a black and white parent is that the child learns to look at both cultures equally. This is an asset since all people need to live in a multi-racial world. From this the child can form a bridge between the two cu...

Palliative Care - Essay Example Legal consideration According to the South Australia advance care-directives act 2013, impaired decision-making capability is one of the major legal considerations during the care of a patient with a life-limiting illness. According to the impaired decision-making capacity act (section 7), a person is taken to be impaired in decision making if either the person is not capable of understanding any information that may be relevant to decision or is incapable of retaining an information made (South Australia. 2013, pp. 10-34). In relation to the case, Mr. Martin Cavanagh was considered having a normal decision-making capacity despite presenting with a terminal illness. This is because the patient was well oriented to time, space and person and could make viable decisions. In relation to the patent refusal of service operation guideline, (SAAS, 2013, p.1), an adult aged 16 years and above has the right to refuse treatment if he/she feels the treatment is either not beneficial or leads to harm. According to this concept, Mr. Martin Cavanagh had a right to refuse treatment. The patient in this instance has a right to choose a place for care provision like in his/her home or at a hospice. Refusal of health care services is a provision of the advanced care directive. Ethical considerations Autonomy is a crucial ethical consideration in the management of a patient with a life-limiting condition. At all instances, when the patient is capable of making his/her decisions, the right to autonomy must always be observed.

Discussion - Essay Example 6.2 User Profile The user profile mainly consisted of six elements that allowed the researcher to understand the profile history of each Umrah Company. These elements included the following: 1- Length of Service 2- Total Number of Employees 3- Number of Employees Dedicated to e-services 4- PC History 5- Computers Owned 6- Number and Average age of Computer Literacy Staff 1- Length of Service The companies that have 10 years or less are likely to adopt to electronic services compared to the older ones according to the data obtained from the findings of the study. 2- Total Number of Employees The total number of employees has a bearing on the organisation’s chances of adopting the electronic services. This implies that the higher the total number of employees in an organisation, the higher the chances of adopting and presenting higher level of satisfaction and dedication towards electronic services than those with low total number of employees who might find it difficult to impl ement electronic services. 3- Number of Employees Dedicated to e-services Most companies often commit resources to train between 2 and 10 employees in electronic services. ... t of the Umrah services and a minority of companies constituting about 7 % has started working with computers before the new electronic systems (10-15 yrs). 5- Computers Owned The number of computers owned is closely related to the structure of adoption of new technology in companies. This means that the companies which have large numbers of computers are more dedicated towards technologies both inside and outside their work tasks. They also seem to be dedicated towards the adoption of new technologies. On the other hand, those who have small numbers of computers are only using them to access the service providers to accomplish their task requirements and neither fully dedicating themselves to technologies nor involving their end users, â€Å"clients† online. 6- Number and Average age of Computer Literacy Staff The advanced computer literacy states that it is not necessary for the companies to have large numbers of staff computer literacy but only a few who can enhance as well as execute the technical issues that relate to IT requirements. However, the average ages of those with advanced computer literacy was observed to be between 25 and 35 years and they approximately represent the highest percentage of respondents which is 41.9%. According to the moderate computer literacy, it can be seen that the majority of companies have their moderate computer literacy staff of around 2-20. Their average ages range between 25 and 30 years and was the highest in terms of response showing 41.9% while the average age between 20 and 25 years was the lowest. This implies that the majority of companies have their moderate computer literacy staff of around 25 to 30 years and above. According to the no computer literacy, it can be observed that some companies have a large number of

King George I :: essays research papers

King George I King George I was born in 1660 at Osnabuuck, the eldest son of Ernest Augustus-Duke of Brunswick-Lunchburg and first Elector of Hanover. Because his father was the Elector of Hanover, George was the Electoral Price of the Empire. He was also in the imperial army, who faced battles against the Dutch, the Turks, Nine Years War, and in the War of Spanish Succession. George soon became a talented and experienced General. He went on to command in many wars. He eventually became lector of Hanover in 1698(2001 World Book Encyclopedia).   Ã‚  Ã‚  Ã‚  Ã‚  George I married Sophia Dorothea, heiress of Duchy of Brunswick and Zell, in 1682. He and his cousin Sophia had one boy and one girl before the marriage turned sour. George was a bad husband with many mistresses while Sophia had many close guy â€Å"friends.† In 1694, George divorced Sophia and accused her of adultry. Being a prominent male in Hanover, the future king of England had her put into prison for 32 years, where she died in 1726.   Ã‚  Ã‚  Ã‚  Ã‚  George I became King of England in 1714 when his distant cousin Queen Ann died. After Ann’s last surviving child had died in 1700, many people claimed that only her half brother James Francis Edward Stuart, a Roman Catholic and son of King James II, had right to succeed her. In 1701, the parliament passed an Act of Settlement that made sure no Catholic would be Monarch. The act provided that Princess Sophia, a Protestant, would succeed Ann as ruler of England unless Ann had another child. Sophia’s son George, became heir to the throne in August 1714(The Royal Heraldry of England).   Ã‚  Ã‚  Ã‚  Ã‚  King George was 54 years of age when he took the throne. He was said to be undignified without the slightest knowledge of the English language. This prevented him from taking part in cabinet councils. He never bothered to learn the language of his new kingdom, although he already knew Latin, French, and Italian. George also showed no appreciation for the English culture. Englishmen Samuel Johnson summarized his thoughts on King George by saying, â€Å"George I knew nothing and desired to know nothing; do nothing and desired to do nothing,†(Western Civilization Volume II).   Ã‚  Ã‚  Ã‚  Ã‚  Due to George’s little interaction with parliament, it further asserted itself with a new coronation of oath, requiring each monarch to swear to obey parliamentary statutes. It established a mandatory term of office for itself, gained tighter control over the budget and army, and produced a Bill of Rights that guaranteed citizens many liberties.
