Weather: Sunshine fades into rain for weekend

2010-09-03T05:41:00.000-07:00

Start your weekend now.

Thursday and Friday ought to be sunny and warm. At least two of three days of the long weekend could be wet.

The National Weather Service says Thursday will be sunny with a high temperature of 76 degrees and Friday sunny with a high temperature of 77 degrees.

Then the curtain falls: Saturday, 40 percent chance of rain and a high temperature of 65 degrees; Sunday, partly sunny and a high temperature of 63 degrees.; Labor Day, chance of showers and a high temperature of 65 degrees.

So gather ye rosebuds and ye sunbeams while ye may.

Structure plan OK brings Coomera Town Centre closer

2009-02-25T23:30:00.000-08:00

State Government endorsement of the Coomera Town Centre Structure Plan is expected to be welcomed by residents keen to see shops and services delivered in the growth hub.

The plan, developed by Gold Coast City Council with community consultation, will guide development of a town centre with an expected retail catchment of approximately 160,000 people by 2026.

Council’s Sustainable City Future Committee Chairperson, Councillor Peter Young, said the structure plan concentrated future retail and commercial development within a 400 metre walkable radius of the existing Coomera Railway Station and proposed transit interchange.

“It will deliver a transit-oriented centre, easily accessible to residents and visitors,” Cr Young said.

He said the Deputy Premier and Minister for Infrastructure and Planning Paul Lucas had endorsed the structure plan and indicated that the State would make its implementation, through the Planning Scheme, a priority.

“This involves changes to the Coomera Town Local Area Plan (LAP),” Cr Young said.

“We will then be in a position to assess development applications against current planning instruments and against community expectations for the centre.”

Divisional Councillor, Donna Gates, said residents were keen to see services at Coomera.

“Governments of all levels have long flagged this site for a major commercial and retail centre and more and more people are moving to the area,” Cr Gates said.

“The State Government’s commitment to fast-tracking their assessment of the LAP amendments means we can see shops, medical centres, schools and other facilities on the ground faster and that will be welcomed by many people.

“It will also deliver much-needed construction work and employment into the future.”

Doomguy

2009-01-22T05:11:00.000-08:00

The doomguy, also known as Doom Dude, Doom or The Marine, is the character of the Doom series of computer and video games formed by id Software. In all the games, he is a space marine working for the Union Aerospace Corporation (UAC), who never speaks and is by no means referred to by name.

In the Doom novels, the main quality is referred to as Flynn Fly Taggart, which is universally suggested to be the Doomguy from the games. However, Tom Hall's original design draft, also known as Doom Bible, recommended his name was Buddy Dacote. In the Doom film revision, the main character, John Reaper Grimm is also suggested to be the Doomguy. This is a twist because the audience likely expects Sarge to acquire that role.
All of the computer-game renditions of the Doomguy dress in green armour. Reaper from the film story wears combat gear reminiscent of a S.W.A.T. operative.

Camp Adventure

2008-12-11T04:56:00.000-08:00

Camp Adventure is a program run by the University of Northern Iowa that sends American college students to American military bases, embassies, and British Military installations during the world. These students run day camps as well overnight, and sports camps. Counselors also act as lifeguards for the children of military personnel stationed on bases.

Camp Adventure was founded at the University of Oregon in 1985. At its inception, the program sent 12 students to three sites in Korea. In 1997, it sent something like 600 students to 118 program sites in 16 countries, including United Kingdom, Turkey, Russia, Germany, Italy, Spain, Belgium, Bahrain, Kuwait, the Netherlands, Korea, Japan, Hong Kong, and People’s Republic of China, Taiwan, and the United States. The camp counselors are trained in games and first aid, as well as how to deal with the problems that several military children have due to the isolation, frequent moves, and dangerous profession of their parents.

The counselors train for several months at the University of Northern Iowa and other Universities across the nation. They are then sent to the destination for the summer. Students are responsible for their own passport and visas, but the program provides transportation, room, and board. An extensive background check is performed on all counselor applicants. Although the program is based at the University of Northern Iowa, Camp Adventure Youth Services students come from over 80 colleges and universities contribute in this service-learning program that allows them to gain skills and occurrence related to youth services and program management.

Cattle

2008-10-10T01:49:00.001-07:00

Cattle, colloquially referred to as cows, are disciplined ungulates, a member of the subfamily Bovina of the family Bovidae. They are raised as livestock for meat dairy products (milk), leather and as draught animals. In some countries, such as India, they are honored in religious ceremonies and revered. It is expected that there are 1.4 billion head of cattle in the world today.

Cattle were originally known by Carolus Linnaeus as three separate species. These were Bos taurus, the European cattle, including similar types from Africa and Asia, Bos indicus, the zebu,and the extinct Bos primigenius, the aurochs. The aurochs is ancestral to together zebu and European cattle. More newly these three have increasingly been grouped as one species, sometimes using the names Bos primigenius taurus, Bos primigenius indicus and Bos primigenius. Complicating the matter is the capacity of cattle to interbreed with other closely related species. Hybrid individuals and even breeds exist, not only between European cattle and zebu but also with yaks, banteng, gaur, and bison, a cross-genera fusion. Cattle cannot effectively be bred with water buffalo or African buffalo.

Tiger

2008-09-11T00:39:00.000-07:00

The tiger is a mammal of the Felidae family, one of four large cats in the Panther a genus. Native to the mainland of southeastern Asia, the tiger is an apex predator and the largest feline species in the world, similar in size to the biggest fossil felids. The Bengal Tiger is the most general subspecies of tiger, constituting approximately 80% of the entire tiger population, and is found in India, Bangladesh, Bhutan, Myanmar, and Nepal. An endangered species, the popular of the world's tigers now live in captivity.

The tiger is introverted and territorial, preferring cover in deep forest, but also ranging in open areas. The cat hunts by stalk-and-ambush and may take a variety of mid- and large-sized prey, particularly ungulates. Males are much larger than females and have bigger home ranges. Amongst the nine extant tiger subspecies, there is major size variation.

Dance studies and techniques

2008-07-09T10:42:00.000-07:00

The Bachelor of Fine Arts grade dance studies specialist permit students to hunt the additional educational aspects of dance with the aim of deepening the student's cultural, conjectural, and aesthetic knowledge. Students in this grade program complete 18-20 credits committed to the interrelated field and are expectant to follow areas that combine their particular interests and career goals in dance. The study of psychology in relation to an interest in dance therapy or the study of exercise science in training for graduate work in dance kinesiology is example of the use of the associated field. With this training in dance and other areas of interest at the undergraduate level, students are equipped to work in frequent dance-related areas or to pursue more advanced and specific study at the graduate level.

What you truly crave to do is spotlight on a mark, start turning your body gradually; make sure you don't move your head starting intent on the spot. When you have turned far adequate you will be enforced to allow you head to turn. In the early stages, don't worry about snapping your head just about to relocate on the spot. Your main concentration should be on starting the turn and holding your deliberation on the spot. If you can achieve that part then the rest will possibly appear without human intervention.

Computers

2008-05-14T10:44:00.000-07:00

Computers take numerous physical forms. The first devices that resemble modern computers date to the mid-20th century, although the computer concept and various machines similar to computers existed prior. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers. Modern computers are based on comparatively tiny integrated circuits and are millions to billions of times more capable while occupying a fraction of the space. Today, simple computers may be made small enough to fit into a wrist watch and be powered from a watch battery. Personal computers in various forms are icons of the information age and are what most people think of as "a computer". However, the most common form of computer in use today is by far the embedded computer. Embedded computers are small, simple devices that are often used to control other devices-for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and even children's toys.

The ability to store and execute lists of instructions called programs makes computers extremely versatile and distinguishes them from calculators. The Church-Turing thesis is a mathematical statement of this versatility: Any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks given enough time and storage capacity.

Polyester

2008-03-14T06:05:00.001-07:00

Polyester is the most widely used manufactured fiber in the United States. Natural fiber polyester fabrics are used for attire and home furnishings. These include bed sheets, bedspreads, curtains and draperies. Polyester fiberfill is also used to substance pillows, comforters and cushion stuffing.

Polyester fabrics sometimes have a "less natural" feel when compared to correspondingly woven fabrics made from ordinary fibers, e.g., cotton. However, polyester fabrics may demonstrate other advantages over natural fabrics, e.g., improved wrinkle confrontation. As a result, polyester fibers are often spun mutually with natural fibers, e.g., cotton, to create a cloth with blended properties.

Polyesters are also used to make bottles, films, oilcloth, liquid crystal displays, holograms, filters, dielectric film for capacitors, film insulation for wire and insulating tapes. Liquid crystalline polyesters are among the first scientifically used liquid crystalline polymers. In general they have extremely good perfunctory properties and are exceptionally heat defiant. For that reason, they can be used as an abradable seal in jet engines.

Thermosetting polyester resins are normally copolymers of unsaturated polyesters with styrene. The unsaturation in the polyester is generally governed by maleic acid or fumaric acid. Another important family is the group of vinyl esters. Here the unsaturation is found in the alcohol part of the polyester. The double bond of the unsaturated polyester reacts with styrene resulting in a 3-D crosslinked structure, the thermoset fabric. The cross-linking is initiated through an exothermic reaction involving an organic peroxide, such as methyl ethyl ketone peroxide or benzoyl peroxide. Unsaturated polyesters are commonly used as casting materials, fiberglass laminating resins, and non-metallic auto-body fillers. Fiberglass reinforced unsaturated polyesters find wide application in bodies of yachts and as body parts of cars.

Race

2008-03-12T07:26:00.001-07:00

The historical definition of race was an unassailable and distinct type or species, sharing distinct cultural characteristics such as creation, temperament, and mental abilities. These races were not conceived as being related with each other, but formed a ladder of inherent value called the Great Chain of Being with Europeans usually at the top. As time progressed, Darwin's theory of evolution was applied to races. By this time, anthropologists considered humans to be related to each other. The word "race," interpreted to mean common tumble, was introduced into English in about 1580, from the Old French rasse (1512), from Italian razza, which may have been derived from the Latin word generatio (a begetting). The etymology can be further traced back to Latin gens (clan, stock, people) and genus (birth, descent, origin, race, stock, family) which in turn comes from the Greek γένος (race, stock, or family).

This late cause for the English and French terms is regular with the thesis that the concept of "race" as defining a very small number of groups of human beings based on extraction dates from the time of Columbus. Older concepts that were also at least partly based on common dive, such as nation and people, entail a much larger number of groupings.

Rain Water

2008-02-29T04:08:00.000-08:00

Lessening raindrops are often depicted in popular culture as "teardrop-shaped" — round at the bottom and narrowing towards the top — but this is untrue. Only drops of water dripping from some sources are tear-shaped at the moment of creation. Small raindrops are nearly globular. Larger ones become increasingly flattened on the bottom, like hamburger buns; very large ones are shaped like parachutes. The shape of raindrops was studied by Philipp Lenard in 1898. He found that small raindrops (less than about 2 mm diameter) are approximately spherical.

As they get larger (to about 5 mm diameter) they become more doughnut shaped. Beyond about 5 mm they become unsteady and fragment. On average, raindrops are 1 to 2 mm in breadth. The biggest raindrops on Earth were recorded over Brazil and the Marshall Islands in 2004 — some of them were as large as 10 mm. The large size is explained by concentration on large smoke particles or by collisions between drops in small regions with particularly high pleased of liquor water.

Raindrops impact at their terminal velocity, which is greater for larger drops. At sea level and without wind, 0.5 mm trickle impacts at about 2 m/s, while large 5 mm drops impact at around 9 m/s. The sound of raindrops hitting water is caused by bubbles of air oscillating underwater.

Generally, rain has a pH slightly under 6. This is because special carbon dioxide dissolves in the dewdrop to form minute quantities of carbonic acid, which then partially dissociates, lowering the pH. In some desert areas, airborne dust contains enough calcium carbonate to counter the natural acidity of rainfall, and rainfall can be neutral or even alkaline. Rain below pH 5.6 is considered acid rain.

Plastic

2008-02-12T04:09:00.001-08:00

Plastic can be classified in many ways, but most generally by their polymer backbone. Other classifications include thermoplastic, thermoset, elastomer, engineering plastic, addition or compression or polyaddition, and glass transition temperature.

Some plastics are partly crystalline and partially amorphous in molecular composition, giving them both a melting point and one or more glass transitions (temperatures above which the extent of localized molecular is considerably increased). So-called semi-crystalline plastics include polyethylene, polypropylene, poly (vinyl chloride), polyamides (nylons), polyesters and some polyurethanes. Many plastics are entirely amorphous, such as polystyrene and its copolymers, poly (methyl methacrylate), and all thermosets.

Plastics are polymers: long chains of atoms bonded to one another. Common thermoplastics range from 20,000 to 500,000 in molecular weight, while thermosets are tacit to have infinite molecular weight. These chains are made up of many repeating molecular units, known as "repeat units", derived from "monomers"; each polymer chain will have several 1000's of repeat units. The vast majority of plastics are composed of polymers of carbon and hydrogen alone or with oxygen, nitrogen, chlorine or sulfur in the backbone. The backbone is that part of the chain on the main "path" linking a large number of repeat units together. To vary the properties of plastics, both the repeat unit with different molecular groups "hanging" or "pendant" from the backbone, (usually they are "hung" as part of the monomers before linking monomers together to form the polymer chain). This customization by repeat unit's molecular structure has allowed plastics to become such an essential part of twenty first-century life by fine tuning the properties of the polymer.

Media

2008-01-31T08:16:00.001-08:00

Media bias is a term used to describe a real or supposed bias of newspapers and news producers within the mass media, in the selection of which events will be reported and how they are covered. The term "media bias" usually refers to a invasive or widespread bias contravening the standards of newspaper journalism, rather than the perception of an individual journalist or article. The direction and degree of media bias in various countries is extensively disputed, although its causes are both practical and theoretical.

Practical limitations to media objectivity include the inability of journalists to report all available stories and facts, and the requirement that selected facts be linked into a coherent tale (Newton 1989). Since it is impossible to report everything, some bias is inevitable. Government persuade, including overt and covert censorship, biases the media in some countries. Market forces that can result in a biased presentation include the ownership of the news source, the selection of staff, the preferences of an intended audience, or pressure from advertisers. Political affiliations arise from ideological positions of media owners and journalists. The space or air time available for reports, as well as deadlines needed to be met, can lead to incomplete and it sounds as if biased stories.

power

2008-01-24T09:48:00.001-08:00

Power is the rate at which work is performed or energy is transmitted or the amount of energy essential or finished for a given unit of time. It is many types of conversion
Power.
Power (physics) is the quantity of work done or energy transferred per unit of time. Motive power is power which moves great, such as output of a motor. Electric power generation is the process of converting any form of energy to electrical energy.
Power station, a capability for generating electricity, nuclear power, the conversion of nuclear force to electricity, solar power, the translation of solar energy to electricity, wind power, the conversion of wind energy to electricity, wave power, the conversion of signal energy to electricity, tidal power, the conversion of energy of the tides energy to electricity, geothermal power, the conversion of geothermal power to electricity, hydropower, the conversion of possible or kinetic energy of water to electricity, Optical power of a lens is the opposite of its focal length, Effective radiated power in radio telecommunications is a calculate of radio station antennas.

Laptop

2007-12-20T07:20:00.000-08:00

A laptop computer, or simply laptop, is a small mobile computer, which usually weighs 2-18 pounds (1-6 kilograms), depending on mass, materials, and other factors. Laptops usually run on a single main battery or from an external AC/DC adapter which can blame the battery while also supplying power to the processor itself. Many computers also have a 3 volt cell to run the clock and other processes in the occurrence of a power failure.

As personal computers, laptops are skilled of the same tasks as a desktop computer, although they are classically less powerful for the similar price. They contain components that are similar to their desktop counterparts and perform the same functions, but are miniaturized and optimized for mobile use and capable power consumption. Laptops usually have liquid crystal displays and most of them use unusual memory modules for their chance access memory (RAM), for instance, SO-DIMM in lieu of the superior DIMMs. In addition to a built-in keyboard, they may utilize a touchpad or a pointing stick for input, though an outside keyboard or mouse can frequently be attached.

Music

2007-12-14T07:14:00.001-08:00

Music is an art form consisting of sound and silence expressed through time. Elements of sound as used in music are pitch, rhythm and sonic qualities of timbre, articulation, dynamics, and texture.

The creation, performance, significance and even the definition of music, varies according to culture and social context. Music ranges from strictly organized compositions and performances to improvisational or aleatoric forms. For purposes of discussion and exploration of the topic, music is divided into genres and sub-genres, although the dividing lines and relationships between music genres are often unclear and/or controversial. Within "the arts", music can be classified as a performing art, a fine art, or an auditory art form.

Music may also involve generative forms in time through the construction of patterns and combinations of natural stimuli, principally sound. Music may be used for artistic or aesthetic, communicative, entertainment, ceremonial or religious purposes and by many composers purely as an academic instrument for study.

Banana

2007-11-28T04:57:00.000-08:00

Banana is the common name used for herbaceous foliage of the genus Mesa, and is also the name given to the fruit of these plants. They are resident to the tropical region of Southeast Asia, the Malay Archipelago, and Australia. They are cultivated primarily for their fruit, and to a lesser level for the production of fiber and as ornamental plants. Because of their size and structure, banana plants are often wrong for trees. The main or upright growth is called a pseudo stem, which for some species can gain a height of up to 2–8 m, with leaves of up to 3.5 m in length. Each pseudo stem produces a single group of bananas, before dying and being replaced by a new pseudo stem.

Bananas are grown in 132 countries worldwide, additional than any other fruit crop. In popular culture and commerce, banana usually refers to soft, sweet dessert bananas that are usually eaten raw. The bananas from a collection of cultivars with firmer, starchier fruit are generally used in cooking rather than eaten raw. Bananas may also be dried up and ground into banana flour. Although the wild species have fruits with numerous large, hard seeds, virtually all culinary bananas have unplanted fruits. Bananas are classified any as dessert bananas or as green cooking bananas.

Propeller aircraft

2007-11-20T06:33:00.000-08:00

Smaller and older propeller aircraft make use of reciprocating internal combustion engines that turns a propeller to create force. They are quieter than jet aircraft, but they fly at lower speeds, and have lower load capacity compared to similar sized jet powered aircraft. However, they are considerably cheaper and much more cost-effective than jets, and are usually the best option for people who need to transport a few passengers and/or small amounts of cargo. They are also the aircraft of choice for pilots who wish to own an aircraft.

Turboprop aircraft are a intermediate point between propeller and jet: they use a turbine engine similar to a jet to turn propellers. These aircraft are popular with traveler and regional airlines, as they tend to be more economical on shorter journeys.

Biotechnology

2007-10-29T08:16:00.000-07:00

Biological technology is technology based on biology, particularly when used in agriculture, food science, and medicine. Biotechnology means any technological application that uses biological systems, living organisms, or derivatives thereof, to construct or change products or processes for specific use. Biotechnology combines disciplines like genetics, molecular biology, biochemistry, embryology and cell biology, which are in turn allied to practical disciplines like chemical engineering, information technology, and robotics.Biotechnology can also be defined as the exploitation of organisms to do practical things and to provide useful products.

One characteristic of biotechnology is the directed use of organisms for the manufacture of organic products (examples include beer and milk products). For another example, naturally present bacteria are utilized by the mining industry in bioleaching. Biotechnology is also used to recycle, treat waste, clean up sites infected by industrial activities, and produce biological weapons.

Electrostatic induction theory

2007-10-26T09:27:00.001-07:00

Another theory is that opposite charges are driven apart by the above mechanism and power is stored in the electric field between them. Cloud electrification appears to necessitate strong updrafts which hold water droplets upward, supercooling them to -10 to -20 C. These have a collision with ice crystals to form a soft ice-water mixture called graupel. The collisions result in a slight positive charge being transferred to ice crystals, and a slight negative charge to the graupel. Updrafts drive lighter ice crystals upwards, causing the cloud top to accumulate increasing positive charge. The heavier negatively charged graupel falls towards the middle and lower portions of the cloud, building up an increasing negative charge. Charge separation and accumulation continue until the electrical potential becomes sufficient to initiate lightning discharges, which occurs when the gathering of positive and negative charges forms a adequately strong electric field.

Elephant

2007-10-10T09:30:00.000-07:00

The African and Asian elephants are separate classes. African elephants, at up to 4 m tall and weighing 7500 kg, are usually larger than the Asian species and they have superior ears. Both male and female African elephants have long tusks, while their Asian counterparts have shorter ones, with those of females varnishing little. African elephants have a dished back, smooth forehead and two fingers at the tip of their swimming suit, whereas the Asian have an arched reverse, two humps on the brow and only one finger at the tip of their trunks.

Resistance

2007-09-24T07:19:00.000-07:00

Electrical resistance is a compute of the degree to which an object opposes an electric current through it. The SI unit of electrical resistance is the ohm. Its reciprocal quantity is electrical conductance calculated in siemens. Electrical resistance shares some conceptual parallels with the mechanical notion of friction.
The resistance of an object determines the amount of current through the object for a known voltage across the object I=V/R, where R is the resistance of the object, measured in ohms, equivalent to J•s/C2, V is the voltage across the object, measured in volts, I is the current through the object, measured in amperes. In metals, the Fermi level lies in the conduction band giving rise to free transfer electrons. However, in semiconductors the position of the fermi level is within the band gap, closely half way between the conduction band minimum and valence band maximum for intrinsic semiconductors.

Beach volleyball

2007-09-05T09:08:00.001-07:00

Beach volleyball is an Olympic group sport played on sand. Two teams, positioned on either side of a net which divides rectangular court, hit volleyball, usually using the hands or arms. It is evolved from indoor volleyball, and the two sports remain very similar: a team scores points by foundation the ball on the opponents' court, or when the opposing team commits a fault teams can contact the ball no more than three times before the ball crosses the net; and consecutive contacts must be made by unlike players. The most important differences between beach and indoor volleyball are the playing surface, and the team size. There are many minor differences as well, including each half of the court actions 8 by 8 meters.
If a jamming player touches the ball, but it continues onto his side of the net, the block counts as the first contact. Open-hand dinks, where a player uses his or her finger tips to redirect the ball into the opponent's court, are banned. It is legal to cross under the net as long as doing so does not hamper with the opponents' attempt to play the ball. Players are not necessary to rotate positions; they must alternate check, but there are no rotation errors.

Mobile phone

2007-08-29T03:43:00.000-07:00

A mobile telephone or cellular telephone is a long-range, portable electronic machine used for mobile communication. In addition to the normal voice function of a telephone, current mobile phones can carry many additional services such as SMS for text messaging, email, packet switching for access to the Internet, and MMS for sending and getting photos and video. Most current mobile phones connect to a cellular network of bottom stations, which is in turn interconnected to the public switched telephone network.
Mobile news services are increasing with many organizations providing on-demand news armed forces by SMS. Some also provide instant news pushed out by SMS. Mobile telephony also facilitates activism and public journalism being explored by Reuters and Yahoo and small sovereign news companies such as Jasmine News in Sri Lanka. Also companies like Monster are starting to offer mobile services such as job search and career information.
The total worth of mobile data services exceeds the value of paid services on the internet, and was worth 31 B dollars in 2006. The largest categories of mobile services are music, picture downloads, video gaming, adult entertainment, gambling, video/TV.

Social network

2007-08-17T09:31:00.000-07:00

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.

Toy

2007-08-08T10:14:00.000-07:00

A Toy is an item used in play. Toys are usually related with children and pets, but it is not unusual for adult humans and some non-domesticated animals to play with toys. Many items are manufactured to serve as toys, but items shaped for other purpose can also be used as toys. A child may pick up a domestic item and 'fly' it around pretending that it is an airplane, or an animal might play with a pinecone by batting at it, chasing it, and throwing it up in the air. Some toys are intended largely as collector's items and are not to be played with.The origin of toys is prehistoric; dolls representing infants, animals, and soldiers, as well as representations of tools used by adults are pleasure found at archaeological sites. The origin of the word toy is unknown, but it is understood that it was first used in the 14th century.

Toys and play in general are an important part of the method of learning about the world and growing up. The young use toys and play to discover their identity, help their bodies grow tough, learn cause and effect, explore relationships, and practice skills they will need as adults. Adults use toys and play to form and strengthen social bonds, teach the young, memorize and reinforce lessons from their own youth, exercise their minds and bodies, practice skills they may not use every day, and decorate their living spaces. Toys are more than simple amusement, and they and the way they are used greatly influence most aspects of life.

Solar wind

2007-07-27T02:55:00.001-07:00

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

2007-07-23T02:49:00.001-07:00

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.

Safety
