Global Marketplaces and Business Centers Research Paper

Global Marketplaces and Business Centers - Research Paper Example With advances in information technology, there have been lower costs to communicate and interact across national and international boundaries. This has seen many businesses facing the potential to expand and increase their markets into other foreign countries. With information technology, it has been possible to transfer resources, materials, and capital to wherever they are likely to yield the highest profits (Buono 29). The term ‘business center’ has a number of meanings. A business centre may be defined as a popular place in which many businesses are able to rent rooms for events, meetings or offices. A business centre is also part of a town, city, country, or region where the main business activities and premises such as banks, shopping malls, factories, or offices are located. In business centers, there are usually a lot of financial and business activities. Business centres usually represent places where business professionals, large companies, and other small busi ness are able to operate from. These centres usually provide businesses with conference rooms, space to operate, office equipment, telecommunication services, support staff, and other amenities necessary for businesses to be conducted smoothly. The two terms are sometimes used to refer to places, regions, or countries that are well known business destinations (Porter 56). Global marketplaces and business centres can be assessed by looking at how the world’s GDP is shared. According to statistics appearing in the 2006 World Bank Development Report (292-300), the United States has 29% of the world’s GDP, the European Union 31%, Japan 11%, Canada 2%, and the rest of the world 27% as of 2004. The global marketplaces of North America include United States, the Caribbean countries, Central American countries, Greenland and Mexico. All these countries have a population of over 507 million people who produce close to 33% of the world’s total output. The US had the large st economy of $ 40.9 trillion GDP in 2004. Another global marketplace worth mentioning is Canada. It population is about 32 million, and it is a major exporter since its exports account for close to its GDP of 37% realized in 2004 which amounted to $ 980 billion (Rosenblooum 78). Western Europe consists of nations which are among the most successful, and attract the highest number of businesses and business ventures. The Western European countries have wealthy people who can buy many products from other marketplaces. Western European countries that make up global market places are divided into members of the European Union. It also consists of other countries that belong to the region. Some of these countries that are global marketplaces within Western Europe include Germany, France, the United Kingdom, and other like Norway, Iceland, and Switzerland (Hofstede 77). Eastern and Central Europe also have many countries that are considered global marketplaces and business centres. The c ountries that make up global marketplaces in Central Europe include Romania, Poland, Hungary, Slovak Republic, Czech Republic, Bulgaria, Austria, Albania, Montenegro, Serbia, Slovenia, Macedonia, Croatia, and Bosnia. The countries in Eastern Europe that are known to be global marketplaces are the 15 countries that were formed as a result of the Soviet Union’s disintegration. These regions have undergone numerous economic, political, and social changes during the past decade to be where they are today. Most of the

Explain How Helicopters Fly - Essay Example Its flight features allow movement in all direction: upwards, downwards, sideways, forward as well as in reverse direction. This flexibility allows the helicopter to be flown in small and congested areas where it is not possible to land the airplanes. Since it can fly in any direction, it has a lot of parameters to take care of while flying. Therefore, the pilot needs to be very skilled and capable and must give full attention while flying. Helicopters not only move in all three dimensions but can also rotate and hover at one point in air. These features, although, make it a unique mode of transport, also make it a very complex machine to understand as well as to pilot. The main parts of helicopter are: ïÆ'Ëœ Main Rotor – The vertically mounted rotor in center ïÆ'Ëœ Fuselage – The main body of helicopter ïÆ'Ëœ Transmission system – Speed control mechanism of rotors ïÆ'Ëœ Tail boom – Rear portion on which the tail rotor is mounted ïÆ'Ëœ Tail rotor – Small horizontal axis rotor at the rear ïÆ'Ëœ Engine – Main engine used to spin the shaft To understand the flight of a helicopter, we can begin from the simple vertically up and down motion. For a helicopter to move upwards, it needs wings that have air moving on its surface in one direction. In case of an airplane, the wings are fixed and the whole plane moves forward for the air to move on the surface of wings and generate lift. However, in case of helicopter we keep it on the same spot. Instead, the wings are rotated to generate the desired lift effect. Wings are shaped in such a manner that they deflect the air downwards and as a reaction, the helicopter is lifted. This shape of the wings is called airfoil. Two or more wings are mounted on a shaft and the shaft is made to rotate thereby, giving a continuous motion to the wings. This rotating wings and shaft are collectively called the main rotor. The main rotor is the most important part of any helicopter. It not only generates the lift force required for the helicopter to fly but also provides for the lateral moveme nt, spinning and changing the altitude. The rotor has to be very strong as it supports all the forces on the helicopter and its weight. The wings have a swivel mechanism at the point where they connect to the rotor. This swivel functionality allows for changing the angle of blades, which changes the path of air. To affect lift, the angle of blades needs to be altered with respect to the oncoming wind. This is known as the angle of attack. The angle alteration mechanism for all wings is collectively called the hub. A device known as the swash plate assembly makes the adjustment of the angles of the rotor blades. The swash plate assembly has two plates, fixed swash plate and a rotating swash plate. The swash plate assembly has two main functions: Firstly, it changes the angle of all the blades simultaneously. It increases the overall lift, thereby gaining or losing altitude. Secondly, the swash plate can change the angle of individual blades while revolving. This gives the flexibility to a helicopter to move in any direction. This alteration of angle, called pitch, is carried out by means of the pitch control rods, which control the function of rotating swash pl
