A currency is a standardization of money in any form, in use or circulation as a medium of exchange, for example banknotes and coins.A more general definition is that a currency is a system of money in common use within a specific environment over time, especially for people in a nation state. Under this definition, the Pound sterling (£), euro (€), Japanese yen (¥), and U.S. dollars (US$) are examples of (government-issued) fiat currencies. Currencies may act as stores of value and be traded between nations in foreign exchange markets, which determine the relative values of the different currencies. Currencies in this sense are either chosen by users or decreed by governments, and each type has limited boundaries of acceptance; i.e., legal tender laws may require a particular unit of account for payments to government agencies.
Food is any substance consumed by an organism for nutritional support. Food is usually of plant, animal, or fungal origin and contains essential nutrients such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells to provide energy, maintain life, or stimulate growth. Different species of animals have different feeding behaviours that satisfy the needs of their metabolisms and have evolved to fill a specific ecological niche within specific geographical contexts.
Space is a three-dimensional continuum containing positions and directions.In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.
A forklift (also called industrial truck, lift truck, jitney, hi-lo, fork truck, fork hoist, and forklift truck) is a powered industrial truck used to lift and move materials over short distances.
An accountant is a practitioner of accounting or accountancy. Accountants who have demonstrated competency through their professional associations' certification exams are certified to use titles such as Chartered Accountant, Chartered Certified Accountant or Certified Public Accountant, or Registered Public Accountant. Such professionals are granted certain responsibilities by statute, such as the ability to certify an organization's financial statements, and may be held liable for professional misconduct. Non-qualified accountants may be employed by a qualified accountant, or may work independently without statutory privileges and obligations.
An actor (or actress for females) is a person who portrays a character in a performance. The actor performs "in the flesh" in the traditional medium of the theatre, or in modern mediums such as film, radio, and television. The analogous Greek term is ὑποκριτής (hupokritḗs), literally "one who answers". The actor's interpretation of their role pertains to the role played, whether based on a real person or fictional character. Interpretation occurs even when the actor is "playing themselves", as in some forms of experimental performance art, or, more commonly; to act, is to create, a character in performance.
Office administration (shortened as Office AD and abbreviated as OA) is a set of day-to-day activities or tasks that are related to the maintenance of an office building, financial planning, record keeping and billing, personal development, physical distribution and logistics, within an organization. An employee that undertakes these activities is commonly called an office administrator or office manager, and plays a key role in any organizations infrastructure, regardless of the scale. Many administrative positions require the candidate to have an advanced skill set in the software applications Microsoft Word, Excel and Access
Admiral is the rank, or part of the name of the ranks, of the highest naval officers. It is usually abbreviated to "Adm" or "ADM". The rank is generally thought to have originated in Sicily from a conflation of Arabic: أمير البحر, amīr al-baḥr, "commander of the sea", with Latin admirabilis ("admirable") or admiratus ("admired"), although alternative etymologies derive the word directly from Latin, or from the Turkish military and naval rank miralay. In the Commonwealth and the U.S., a "full" admiral is equivalent to a "full" general in the army, and is above vice admiral and below admiral of the fleet (or fleet admiral). In NATO, admirals have a rank code of OF-9 as a four-star rank.
Advertising is an audio or visual form of marketing communication that employs an openly sponsored, nonpersonal message to promote or sell a product, service or idea.Sponsors of advertising are often businesses who wish to promote their products or services. Advertising is differentiated from public relations in that an advertiser usually pays for and has control over the message. It is differentiated from personal selling in that the message is nonpersonal, i.e., not directed to a particular individual. Advertising is communicated through various mass media, including old media such as newspapers, magazines, Television, Radio, outdoor advertising or direct mail; or new media such as search results, blogs, websites or text messages. The actual presentation of the message in a medium is referred to as an advertisement or "ad".
Advertising is the practice and techniques employed to bring attention to a product or service. Advertising aims to present a product or service in terms of utility, advantages, and qualities of interest to consumers. It is typically used to promote a specific good or service, but there are a wide range of uses, the most common being commercial advertisement.
An advocate is a type of professional person in several different legal systems and it is also a commonly used honorific for remarkable lawyers, such as in "Adv. ir SAlberico Gentili". The broad equivalent in many English law-based jurisdictions can be a barrister. However, in Scottish, South African, Italian, French, Spanish, Portuguese, Scandinavian, Polish, South Asian and South American jurisdictions, advocate is also a word to indicate lawyers of superior classification.
Aerobics is a form of physical exercise that combines rhythmic aerobic exercise with stretching and strength training routines with the goal of improving all elements of fitness (flexibility, muscular strength, and cardio-vascular fitness). It is usually performed to music and may be practiced in a group setting led by an instructor (fitness professional), although it can be done solo and without musical accompaniment. With the goal of preventing illness and promoting physical fitness, practitioners perform various routines comprising a number of different dance-like exercises. Formal aerobics classes are divided into different levels of intensity and complexity. A well-balanced aerobics class will have five components: warm-up (5-10 minutes), cardio vascular conditioning (25-30 minutes), muscular strength and conditioning (10-15 minutes), cool-down (5-8 minutes) and stretching and flexibility (5-8 minutes). Aerobics classes may allow participants to select their level of participation according to their fitness level. Many gyms offer a variety of aerobic classes. Each class is designed for a certain level of experience and taught by a certified instructor with a specialty area related to their particular class.
Agricultural machinery is machinery used in farming or other agriculture. There are many types of such equipment, from hand tools and power tools to tractors and the countless kinds of farm implements that they tow or operate. Diverse arrays of equipment are used in both organic and nonorganic farming. Especially since the advent of mechanised agriculture, agricultural machinery is an indispensable part of how the world is fed.
Agriculture is the cultivation and breeding of animals, plants and fungi for food, fiber, biofuel, medicinal plants and other products used to sustain and enhance human life.[1] Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization. The study of agriculture is known as agricultural science. The history of agriculture dates back thousands of years, and its development has been driven and defined by greatly different climates, cultures, and technologies. Industrial agriculture based on large-scale monoculture farming has become the dominant agricultural methodology.
The human immunodeficiency virus (HIV) is a retrovirus that attacks the immune system. It can be managed with treatment. Without treatment it can lead to a spectrum of conditions including acquired immunodeficiency syndrome (AIDS)
A hot air balloon is a lighter-than-air aircraft consisting of a bag, called an envelope, which contains heated air. Suspended beneath is a gondola or wicker basket (in some long-distance or high-altitude balloons, a capsule), which carries passengers and a source of heat, in most cases an open flame caused by burning liquid propane. The heated air inside the envelope makes it buoyant, since it has a lower density than the colder air outside the envelope. As with all aircraft, hot air balloons cannot fly beyond the atmosphere. The envelope does not have to be sealed at the bottom, since the air inside the envelope is at about the same pressure as the surrounding air. In modern sport balloons the envelope is generally made from nylon fabric, and the inlet of the balloon (closest to the burner flame) is made from a fire-resistant material such as Nomex. Modern balloons have been made in many shapes, such as rocket ships and the shapes of various commercial products, though the traditional shape is used for most non-commercial and many commercial applications.
The hot air balloon is the first successful human-carrying flight technology. The first untethered manned hot air balloon flight in the world was performed in Paris, France, by Jean-François Pilâtre de Rozier and François Laurent d'Arlandes on November 21, 1783, in a balloon created by the Montgolfier brothers. The first hot air balloon flown in the Americas was launched from the Walnut Street Jail in Philadelphia on January 9, 1793, by the French aeronaut Jean Pierre Blanchard. Hot air balloons that can be propelled through the air rather than simply drifting with the wind are known as thermal airships.
An air force, also known in some countries as an aerospace force or air army, is in the broadest sense, the national military branch that primarily conducts aerial warfare. More specifically, it is the branch of a nation's armed services that is responsible for aerial warfare as distinct from an army, navy, or a marine corps. Typically, air forces are responsible for gaining control of the air, carrying out strategic and tactical bombing missions, and providing support to land and naval forces.
The term "air force" may also refer to a tactical air force or numbered air force, which is an operational formation either within a national air force or comprising several air components from allied nations. Air forces typically consist of a combination of fighters, bombers, helicopters, transport planes and other aircraft.
Many air forces are also responsible for operations of the military space, intercontinental ballistic missiles (ICBM), and communications equipment. Some air forces may command and control other air defence assets such as anti-aircraft artillery, surface-to-air missiles, or anti-ballistic missile warning networks and defensive systems. Some nations, principally Russia, the former Soviet Union and countries who modelled their militaries along Soviet lines, have or had an air defence force which is organizationally separate from their air force.
Peace-time/non-wartime activities of air forces may include air policing and air-sea rescue.
Air forces are not just composed of pilots, but also rely on a significant amount of support from other personnel to operate. Logistics, security, intelligence, special operations, cyber space support, maintenance, weapons loaders, and many other specialties are required by all air forces.
An aircraft (pl. aircraft) is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons.Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air."
