Air Condition

The name air conditioning most commonly refers to the cooling and dehumidification of indoor air for thermal relieve. In a broader sense, the term can refer to any form of cooling, heating, ventilation or disinfection that modifies the condition of air. An air conditioner (AC or A/C in North American English, aircon in British and Australian English) is an appliance, system, or mechanism designed to stabilise the air temperature and moisture within an area (used for cooling as well as heating depending on the air properties at a set time) , typically using a refrigeration cycle but sometimes using desertion, most commonly for comfort cooling in buildings and carrying vehicles.

The concept of air conditioning is known to have been applied in primordial Rome, where channel water was circulated through the walls of certain houses to cool them. Similar techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the sizzling season. Modern air conditioning emerged from advances in chemistry during the 19th century, and the first large-scale electrical air conditioning was invented and used in 1902 by Willis Haviland Carrier.

Leopard

Large wild cat found in Africa and Asia. The background colour of the fur is golden, and the black spots form rosettes that differ according to the mixture; black panthers are simply a colour distinction and retain the patterning as a ‘watered-silk’ effect. The leopard is 1.5–2.5 m/5–8 ft long, including the tail, which may measure 1 m/3 ft. (Species Panthera pardus, family Felidae.)

The snow leopard or ounce (Panthera uncia), which has irregular rosettes of much larger black spots on a light cream or grey background, is a native of mountains in central Asia. The clouded leopard (Neofelis nebulosa) is rather smaller, about 1.75 m/5.8 ft overall, with large blotchy markings rather than rosettes, and is found in Southeast Asia. There are seven species, of which six are in danger of extinction, including the Amur leopard and the South Arabian leopard. One subspecies, the Zanzibar leopard, may already be extinct. The last Judean desert leopard died May 1995, although a small population survives in the Negev Desert.

Coconut

The coconut palm is grown throughout the tropical world, for decoration as well as for its many cooking and non-culinary uses, virtually every part of the coconut palm has some human use.The flowers of the coconut palm are polygamomonoecious, with both male and female flowers in the similar inflorescence. Flowering occurs continuously, with female plants producing seeds. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating. Coconut water can be used as an intravenous fluid.

Nearly all parts of the coconut palm are useful, and the palms have a comparatively high yield, it therefore has important economic value. The name for the coconut palm in Sanskrit is kalpa vriksha, which translates as the tree which provides all the requirements of life. In Malay, the coconut is known as pokok seribu guna, the tree of a thousand uses. In the Philippines, the coconut is generally given the title Tree of Life. The white, fleshy part of the seed is safe to eat and used fresh or dried in cooking.

Inductor

An inductor is a passive electrical device working in electrical circuits for its property of inductance. Inductance is an consequence which results from the magnetic field that forms around a current carrying conductor. Electrical current through the conductor creates a magnetic flux relative to the current. A change in this current creates a change in magnetic flux that, in turn, generates an electromotive force that acts to oppose this change in current. Inductance is a calculate of the generated emf for a unit modify in current. An inductor with an inductance of 1 henry produces an emf of 1 V when the current through the inductor changes at the rate of 1 ampere per second. The number of turns, the area of each loop/turn, and what it is wrapped around influence the inductance.

An inductor opposes changes in the current. An ideal inductor would offer no resistance to a constant direct current, however, only superconducting inductors have truly zero electrical resistance. Inductors are used expansively in analog circuits and signal processing.

Inca Rope bridge

Inca Rope bridges were simple suspension bridges over canyons and gorges to present access for the Inca Empire. Bridges of this type were suitable for use since the Inca people did not use wheeled transport - traffic was incomplete to pedestrians and livestock. These bridges were an intrinsic part on the Inca road scheme and are an excellent example of Inca innovation in engineering. They were frequently used by Chasqui runners delivering messages throughout the Inca Empire.

The construction of these bridges amounted to a pair of stone anchors on each side of the canyon with immense cables of woven ichu grass linking these two pylons together. Adding to this construction, two additional cables acted as guardrails. The cables which supported the foot-path were unbreakable with plaited branches. This multi-structure system made these bridges strong enough to even carry the Spaniards while riding horses after they indoors. However, these massive bridges were so heavy that they tended to sag in the middle, and this caused them to bend in high winds.

Wilderness

Wilderness is generally defined as a natural environment on Earth that has not been directly modified by human activity. Ecologists consider wilderness areas to be an integral part of the planet's self-sustaining natural ecosystem.

The word, wilderness, derives from the notion of wildness; in other words that which is not controllable by humans. The word's etymology is from the Old English wilderness, which in turn derives from wilder meaning wild beast (wild + deor = beast, deer). From this point of view, it is the wildness of a place that makes it a wilderness. The mere presence or activity of people does not disqualify an area from being wilderness. Many ecosystems that are, or have been, inhabited or influenced by activities of people may still be considered wild. This way of looking at wilderness includes areas within which natural processes operate without very noticeable human interference.

Looked at through the lens of the visual arts, nature and wildness have been important subjects in various epochs of world history. An early tradition of landscape art occurred in the Tang Dynasty. The tradition of representing nature as it is became one of the aims of Chinese painting and was a significant influence in Asian art. Artists learned to depict mountains and rivers "from the perspective of nature as a whole and on the basis of their understanding of the laws of nature … as if seen through the eyes of a bird." In the 13th century, Shih Erh Chi listed "scenes lacking any places made inaccessible by nature," as one of the 12 things to avoid in painting.

Calculator

A calculator is a machine for performing calculations. Although modern calculators often incorporate a general purpose computer, the device is calculated for performing specific operations, rather than for flexibility. Modern calculators are more convenient than most computers, though some Pads are comparable in amount to handheld calculators.

In the past, some calculators were as huge as today's computers. The first automatic calculators were mechanical desktop devices which were replaced by electromechanical desktop calculators, and then by electronic devices using first sung valves, then transistors, then hard-wired integrated circuit logic. New calculators are electrically powered and come in innumerable shapes and sizes varying from cheap, give-away, credit-card sized models to more sturdy adding machine-like models with built-in printers.

Geography and economics

The Ghana is an African country located on the western side of Africa. The neighbor countries are Burkina Faso, Togo, the Atlantic Ocean, and Cote d’Ivoire. It has a population of nearly 18,100, 703 and a population density may be of 197 people per square mile. The Ghana’s area is 92,098 square miles and the official language is English. The capital city is Accra has around 1, 673,000 residents. There are the physical statistics, which is to be considered.

The great strengths of the country are its natural resources. And also, they are very rich. The big export is Cocoa, which totally accounts for 15% of the world's supply. And also the gold production, now a days, it's exported as more as one million fine ounces. Ghana is also supplying bauxite, diamonds, coffee, rice, cassava, timber and rubber. After 1983, the economy has steadily grown. By the economic recovery policies intact, the economy has raised 5% a year since 1983. Tourism development also grows within Ghana. The Tourist rates are also increasing. With these cash crops, costly goods, and economic restructuring, one would wonder why they need assistance at all.

Beauty Queen

Beauty pageants are usually multi-tiered, through local competitions feeding into the bigger competitions. The worldwide pageants, thus, need hundreds, sometimes thousands, of local competitions. In the United States, there is currently a commercial beauty pageant industry that organizes thousands of local events for all ages for profit supported by magazines like The Crown Magazine and Pride of Pageantry, the online epiczine.com, the Pageant News Bureau and The Crown Magazine, and a crowd of retailers of all from tiaras to cosmetic surgery.

Beauty Queens are selected on many criteria. Every individual pageant will provide to future delegates its exacting methods of competition and scoring. For example, The universal Pageant http://www.worldwidepageant.net has a sole scoring method wherein delegates have the possible of earning a score of 110%. The breakdown is 25% evening wear, 25% physical wear, 50% personal interview, and an optional 10% for a getting portfolio. Diamond Dolls is a pictorial only competition which provides 100% of the score based leading submission of required photos. There are other pageants who take a completely different approach on the whole. Mostly in reference to on-line photogenic pageants, there are competitions in which a winner is selected on a monthly or even weekly basis. There are persons who will take each of these as a "preliminary winner" with the aim upon a "final" competition at some later date. Others delight each of these as a "final" winner and give a title.

In spite of the method of competition, break down of scores or frequency of selection; all are defined as "activity in the form of a beauty pageant." It is up to the person to determine which is best suitable for competition or of particular entertainment interest.

Vehicles

Vehicles are non-living means of moving. They are most repeatedly man-made (e.g. bicycles, cars, motorcycles, trains, ships, and aircraft), although some other means of transportation which are not made by man can also be called vehicles; examples include icebergs and balanced tree trunks. Vehicles may be propelled by animals, e.g. a chariot or an ox-cart. However, animals on their own, though used as a earnings of transportation, are not called vehicles. This includes humans transport another human, for example a child or a disabled person.

Vehicles that do not pass through on land are often called crafts, such as watercraft, sail craft, aircraft, hovercraft and spacecraft. Movement lacking the help of a vehicle or an animal is called locomotion. The word vehicle itself comes from the Latin vehicular.

Football

Football is the name given to a number of different, but correlated, team sports. The most popular of these world-wide is organization football also known as soccer. The English word football is also applied to American football, Australian rules football, Canadian football, Gaelic football, rugby football rugby union and rugby league, and connected games. Each of these codes specific sets of rules is to a greater or lesser area referred to as football and sometimes footy by its followers.
Throughout the history of mankind, the urge to kick at stones and other such objects is thought to have led to many early activities linking kicking and/or running with a ball. Football-like games predate recorded history in all parts of the world, and thus the earliest forms of football are not known.Sheffield Football Club, founded in 1857 in the English city of Sheffield, by former Harrow School pupils Nathaniel Creswick and William Prest, was later recognised as the world's oldest club playing involvement football. However, the club initially played its own code of football the Sheffield system. There were some similarities to the Cambridge rules, but players were allowed to push or hit the ball with their hands, and there was no offside rule at all, so that players known as kick throughs could be permanently placed near the opponents' goal. The code extend to a number of clubs in the area and was popular until the 1870s.

Laser

A laser is a device that emits light through a specific mechanism for which the expression laser is an acronym: Light Amplification by Stimulated release of Radiation. This is a combined quantum-mechanical and thermodynamical procedure discussed in more detail below. As a light source, a laser can have various properties, depending on the reason for which it is designed and calibrated. A typical laser emits light in a contracted, low-divergence beam and with a well-defined wavelength. This is in contrast to a light source such as the incandescent light bulb, which emits into a large solid angle and over a wide spectrum of wavelength. These properties can be summarized in the term coherence.
Light of a specific wavelength that passes through the increase medium is amplified; the neighboring mirrors ensure that the majority of the light makes many passes through the gain medium. Part of the light that is between the mirrors passes through the partially apparent mirror and appears as a beam of light. The process of supplying the power required for the amplification is called pumping and the energy is typically supplied as an electrical current or as light at a diverse wavelength. Most practical lasers contain additional elements that affect properties such as the wavelength of the emitted light and the form of the beam.

Chair

A chair is a piece of furniture for sitting, consisting of a seat, a back, and sometimes arm rests, generally for use by one person. Chairs also often have four legs to support the sit raised above the floor. Without back and limb rests it is called a stool. A chair for more than one human being is a couch, sofa, settee, loveseat, recliner or bench. A split footrest for a chair is known as an ottoman, hassock or poof. A chair mounted in a vehicle or in the stage is simply called a seat. The back often does not expand all the way to the seat to allow for ventilation. Likewise, the back and sometimes the seat are made of permeable materials or have holes drilled in them for decoration and ventilation.
The back may extend above the stature of the head. Headrests for seats in vehicles are important for prevent whiplash injuries to the neck when the vehicle is occupied in a rear-end collision.
Chair design considers planned usage, ergonomics, as well as non-ergonomic functional requirements such as size, stack ability, fold ability, weight, durability, stain confrontation and artistic design.

Monitor

A computer is a display device. A computer programming utility used for examining and modifying memory-resident engine code programs. The computer programming interface for synchronising concurrent access to a set of variables in a computer program. A hardware device that events electrical events such as pulses or voltage levels in a digital computer. A speaker used on stage to allow musicians to hear each other. Also called fold back a video monitor, a television-like device used in studio, lab or analysis environments. A supervisory control system for installations such as SCADA to monitor significant system parameters. Special installations require adapted monitoring installations like transformer monitors or substation monitors. A Hall monitor, one who patrols the entry of a school. A Prefect, schoolboy or schoolgirl given individual authority in some British schools, especially public schools.

Social network

A social network is a social structure made of nodes that are tied by one or more specific types of relatives, such as values, visions, idea, financial exchange, friends, kinship, dislike, trade, web links, sexual relations, disease communication or airline routes.
Social network analysis views common relationships in terms of nodes and ties. Nodes are the individual actors within the networks, and ties are the associations between the actors. Research in a number of academic fields has shown that social networks operate on many levels, from families up to the level of nations, and play a serious role in determining the way problems are solved, organizations are run, and the degree to which individuals succeed in achieving their goals.
In its simplest form, a social network is a map of all of the appropriate ties between the nodes being studied. The network can also be used to decide the social capital of individual actors. These concepts are often displayed in a shared network diagram, where nodes are the points and ties are the lines.

Computation

Computation is a common term for any type of information processing that can be represent mathematically. This includes phenomenon ranging from simple calculations to human idea. In a more narrow meaning, computation is a process following a well distinct model that is understood and can be expressed in an algorithm, protocol, network topology, etc.
These hypothetical computing equipment can be viewed as idealised analog computers which operate on real numbers and are differential, whereas digital computers are partial to computable numbers and are algebraic. Depending on the model select, this may enable real computers to solve problems that are inextricable on digital computers.

Solar wind

The solar wind is a stream of charged particles which are expelled from the upper atmosphere of the sun. It consists mostly of high-energy electrons and protons that are able to get away the sun's gravity in part because of the high temperature of the corona and the high kinetic energy particles gain through a process that is not well understood at this time.

They are directly related to the solar wind, together with geomagnetic storms that can knock out power grids on Earth, auroras and the plasma tail of a comet always pointing away from the sun. While early models of the solar wind used primarily thermal energy to accelerate the material, by the 1960s it was clear that thermal hurrying alone cannot account for the high speed solar wind. Some additional acceleration mechanism is required, but is not presently known, but most likely relates to magnetic fields in the solar atmosphere. The solar wind is answerable for the overall shape of Earth's magnetosphere, and fluctuations in its speed, density, direction, and entrained magnetic field powerfully affect Earth's local space environment.

Capacitance

Capacitance is a measure of the quantity of electric charge stored for a given electric potential. The most general form of charge storage device is a two-plate capacitor. If the charges on the plates are +Q and -Q, and V gives the voltage difference between the plates, then the capacitance is given by c=Q/v. The capacitance of the majority of capacitors used in electronic circuits is several orders of size smaller than the farad. The most ordinary units of capacitance in use today are the millifarad (mF), microfarad (µF), the nanofarad (nF) and the picofarad (pF).

The dielectric constant for a number of very useful dielectrics changes as a function of the applied electrical field, e.g. ferroelectric materials, so the capacitance for these devices is no longer purely a purpose of device geometry. If a capacitor is driven with a sinusoidal voltage, the dielectric constant, or more exactly referred to as the dielectric permittivity, is a function of frequency. A changing dielectric constant with frequency is referred to as a dielectric dispersion, and is governed by dielectric recreation processes, such as Debye relaxation.

Energy meter

An electric meter or energy meter is a machine that measures the amount of electrical energy supplied to a residence or business. These are customers of an electric company.

The most common type is more accurately known as a (kilo) watt-hour meter or a joule meter. They may also record other variables including the time, when the electricity was used. Modern electricity meters operate by continuously measuring the instantaneous voltage and current (amperes) and finding the product of these to give direct electrical power (watts) which is then integrated against time to give energy used (joules, kilowatt-hours etc). The meters fall into two essential categories, electromechanical and electronic. The type of meter described commonly used on a single-phase AC supply. Different phase of meter configurations use additional voltage and current coils. The most general type of electricity meter is the electromechanical induction meter.

Escalator

An escalator is a conveyor transport device for transporting people, consisting of a staircase whose steps move up or down on tracks that keep the surfaces of the individual ladder horizontal. As a power-driven, continuous moving stairway planned to transport passengers up and down short vertical distances, escalators are used around the world to move pedestrian traffic in places where elevators would be impractical. Principal areas of usage include shopping centers, airports, transit systems, convention centers, hotels, and public buildings.

They have the capacity to move large numbers of people, and they can be placed in the same physical space as set of steps. They have no waiting interval, except during very heavy traffic, they can be used to guide people towards main exits and they may be weather-proofed for outdoor use.
