A Mobile Game

A mobile game is a video game has fun on a mobile phone, Smartphone, PDA, handheld computer or any type of handheld or wireless device.

Mobile games are played using the technologies current on the device itself. For networked games, there are different technologies in common use. Examples contain text message (SMS), multimedia message (MMS) or GPRS location identification.

However, there are non networked applications, which simply use the machine platform to run the game software. The games may be installed over the air, they may be side loaded onto the receiver with a cable, or they may be embedded on the handheld devices by the OEM or by the mobile operator.

Mobile games are generally downloaded via the mobile operator's radio network, but in some cases are also loaded into the mobile handsets when purchased, or via infrared connection, Bluetooth or memory card.

Household Electric Fan

A mechanical fan is a device used to create an airflow for the purpose of creature comfort, ventilation, exhaust, or any other gaseous transport.

Mechanically, a fan can be any rotating vane or vanes used for producing currents of air. Fans produce air flows with high volume and low pressure, as opposed to a gas compressor which creates high pressures at a comparatively low volume. A fan blade will often rotate when exposed to an air stream, and devices that take advantage of this, such as anemometers and wind turbines often have designs alike to that of a fan.

Typical applications contain climate control, cooling systems, personal comfort (e.g., an electric table fan), ventilation (e.g., an exhaust fan), winnowing (e.g., separating chaff of cereal grains), removing dust (e.g. sucking as in a vacuum cleaner), drying (usually in addition to heat) and to provide draft for a fire. It is also general to use electric fans as air fresheners, by attaching fabric softener sheets to the protective housing. This causes the fragrance to be carried into the immediate air.

In addition to their utilitarian function, vintage or antique fans, and in exacting electric fans manufactured from the late 1800s through the 1950s, have become a recognized collectible category, and in the U.S.A. an active collector club, the Antique Fan Collectors Association, supports the hobby.

Origin of ice age theory

The plan that, in the past, glaciers had been far more extensive was folk knowledge in some alpine regions of Europe (Imbrie and Imbrie, p25, quote a woodcutter telling de Charpentier of the former extent of the Swiss Grimsel glacier). No single person imaginary the idea. Between 1825 and 1833, Jean de Charpentier assembled proof in support of this idea. In 1836 Charpentier influenced Louis Agassiz of the theory, and Agassiz published it in his book Étude sur les glaciers of 1840.

At this early stage of knowledge, what were being studied were the glacial periods within the past few hundred thousand years, during the present ice age. The far previous ice ages' very existence was unsuspected.

History Of Natural Science

Prior to the 17th century, the objective study of nature was called as natural philosophy. Over the next two centuries, however, a philosophical interpretation of nature was gradually changed by a scientific approach using inductive methodology. The works of Sir Francis Bacon popularized this approach, thereby helping to create the scientific revolution.

By the 19th century the study of science had come into the purview of professionals and institutions, and in so doing it gradually acquired the more recent name of natural science. The term scientist was coined by William Whewell in an 1834 evaluation of Mary Somerville's On the Connexion of the Sciences. However the word did not enter general use until nearly the end of the same century.

Bond Paper

Bond paper is a high quality durable writing paper alike to bank paper but having a weight greater than 50 g/m2. The name comes from it having initially been made for documents such as government bonds. It is now used for letterheads and additional stationery and as paper for electronic printers. Widely employed for realistic work involving pencil, pen and felt-tip marker. Bond paper can occasionally contain rag fibre pulp, which produces a stronger, though rougher, sheet of paper. Nowadays, however, bond paper is presently known as being a smooth white sheet commonly made from normal eucalyptus pulp.

Dot-Matrix Printers

In the common sense many printers rely on a matrix of pixels, or dots, that together form the larger image. However, the term dot matrix printer is specially used for impact printers that use a matrix of small pins to create precise dots. The advantage of dot-matrix over other collision printers is that they can produce graphical images in addition to text; however the text is generally of poorer quality than impact printers that use letterforms (type).

Dot-matrix printers can be generally divided into two major classes:

* Ballistic wire printers (discussed in the dot matrix printers article)

* Stored energy printers

Dot matrix printers can either be character-based or line-based (that is, a single horizontal series of pixels across the page), referring to the pattern of the print head. At one time, dot matrix printers were one of the more general types of printers used for general use - such as for home and small office use. Such printers would have either 9 or 24 pins on the make head, 24-pin print heads were able to print at a advanced quality. Once the price of inkjet printers dropped to the point where they were aggressive with dot matrix printers, dot matrix printers began to fall out of favor for general use.

Several dot matrix printers, such as the NEC P6300, can be upgraded to print in color. This is achieved through the use of a four-color ribbon mounted on a device (provided in an upgrade kit that replaces the standard black ribbon mechanism after installation) that raises and lowers the ribbons as needed. Color graphics are commonly printed in four passes at standard resolution, thus slowing down printing considerably. As a result, color graphics can take up to four times longer to print than regular monochrome graphics, or up to 8-16 times as long at high resolution mode.

Dot matrix printers are still usually used in low-cost, low-quality applications like cash registers, or in demanding, very high volume applications like invoice printing. The fact that they use an impact printing technique allows them to be used to print multi-part documents using carbonless copy paper (like sales invoices and credit card receipts), whereas other printing methods are unusable with paper of this type. Dot-matrix printers are now (as of 2005) quickly being superseded even as receipt printers.

Printing Technology

Printers are routinely confidential by the underlying print technology they employ; numerous such technologies have been developed over the years.

The choice of print engine has a considerable effect on what jobs a printer is suitable for, as various technologies are capable of different levels of image/text quality, print speed, low cost, noise; in addition, some technologies are inappropriate for certain types of physical media (such as carbon paper or transparencies).

Another aspect of printer technology that is frequently forgotten is resistance to alteration: liquid ink such as from an inkjet head or fabric ribbon becomes absorbed by the paper fibers, so documents printed with liquid ink are more difficult to alter than documents printed with toner or solid inks, which do not penetrate below the paper surface.

Checks should also be printed with liquid ink or on special "check paper with toner anchorage". For similar reasons carbon film ribbons for IBM Selectric typewriters bore labels counsel against using them to type negotiable instruments such as checks. The machine-readable lower portion of a check, however, must be printed using MICR toner or ink. Banks and additional clearing houses employ automation equipment that relies on the magnetic flux from these specially printed characters to function properly.

Cybernetics

Cybernetics is the interdisciplinary study of the structure of complex systems, particularly communication processes, control mechanisms and feedback principles. Cybernetics is strongly related to control theory and systems theory.

Contemporary cybernetics began as an interdisciplinary study linking the fields of control systems, electrical network theory, mechanical engineering, logic modeling, evolutionary biology and neuroscience in the 1940s. Other fields of study which have partial or been influenced by cybernetics include game theory, system theory (a mathematical counterpart to cybernetics), psychology (especially neuropsychology, behavioral psychology, and cognitive psychology), and also philosophy, and even architecture.

France And Italy Coins

France

In France the sou (until 1715 sol) was the first name of a coin. It was initial minted in gold, from the 1200s in silver and during the 1700s in copper. The sou tournois was a 12-denier coin, one-twentieth of the livre tournois (Tournois pound), although the sou parisis was a 15-denier coin. After decimalisation in France, the sou became the forename for a five-centime coin, one-twentieth of the French franc(Until the late 1960s, the expression "20 sou" was a synonym of 1 Franc).

To this day, sou is used as jargon for currency, as in j'ai pas de sous. "I'm broke", "I haven't got two bob to rub together".

Sou of copper, coined 1767 designed for Louis XV of France

Italy

The first name of the medieval Italian soldo (plural soldi) was derived from solidus.

Solidus coin

A solidus (the Latin word for solid) was initially a gold coin issued by the Romans.

Julian solidus, ca. 361.It was introduced by Constantine I in the AD 309–10, and was used from beginning to end the Byzantine Empire until the 10th century AD. The coin replaced the aureus as the major gold coin of the Roman Empire.

The name solidus had beforehand been used by Diocletian (284-305) for the gold coin that he introduced, which is different from the solidus introduced by Constantine. The coin was struck at a theoretical worth of 1/72 of a Roman pound (about 4.5 grams). Solidi were wider and thinner than the aureus, with the exclusion of some dumpy issues from the Byzantine Empire. The weight and fineness of the solidus remained moderately constant throughout its long production, with few exceptions. Fractions of the solidus recognized as semisses (half-solidi) and tremissis (one-third solidi) were also produced.

Avitus tremissis, ca. 456.The word soldier is eventually derived from solidus, referring to the solidi with which soldiers were paid.
