iPhone OS

The iPhone OS, known as OS X iPhone in its early history,
is the operating system developed by Apple Inc. for the iPhone and iPod touch.
Like Mac OS X, from which it was derived, it uses the Darwin foundation.
iPhone OS has four abstraction layers: the Core OS layer, the Core Services layer,
the Media layer, and the Cocoa Touch layer. The operating system takes less
than 240 Megabytes of the device's total memory storage.

This operating system did not have an official name until the release
of the first beta version of the iPhone SDK on March 6, 2008. Before then,
Apple marketing literature simply stated that the "iPhone uses OS X,"
a reference to Apple's desktop operating system, Mac OS X.

As of Nov. 4, 2009, there are over 100,000 applications officially available
for the iPhone, and 2 billion downloads had been achieved.

On September 9, 2009, Apple announced version 3.1 of the iPhone OS,
since then 3.1 has been updated to 3.1.2

Suspension bridge

A suspension bridge is a type of bridge in which the deck (the load-bearing portion) is hung below suspension cables on vertical suspenders. While modern bridges of this type date from the early 19th century, earlier bridges without vertical suspenders (simple suspension bridges) date from the 7 th century in Central America.

Suspended-deck suspension bridge with a distinctly arched deck

This type of bridge has cables suspended between towers, plus vertical suspender cables that carry the weight of the deck below, upon which traffic crosses. This arrangement allows the deck to be level or to arc upward for additional clearance. Like other suspensions bridge type, this type often is constructed without falsework.

The suspension cables must be anchored at each end of the bridge, since any load applied to the bridge is transformed into a tension in these main cables. The main cables continue beyond the pillars to deck-level supports, and further continue to connections with anchors in the ground. The roadway is supported by vertical suspender cables or rods, called hangers. In some circumstances the towers may sit on a bluff or canyon edge where the road may proceed directly to the main span, otherwise the bridge will usually have two smaller spans, running between either pair of pillars and the highway, which may be supported by suspender cables or may use a truss bridge to make this connection. In the latter case there will be very little arc in the outboard main cables.

Solar power

Solar power is the generation of electricity from sunlight.

This can be direct as with photostatic (PV), or ind

irect as with concentrating

solar power (CSP), where the

sun's energy is focused to

boil water which is then used to provide power. The solar power gained from photovoltaics can be used to eliminate the need for purchased electricity (usually electricity gained from burning fossil fuels) or, if energy gained from photovoltaics exceeds the home's requirements, the extra electricity can be sold back to the home's supplier of energy, typically for credit. The largest solar power plants, like the 354 MW SEGS, are concentrating solar thermal plants, but recently multi-megawatt photovoltaic plants have been built. Completed in 2008, the 46 MW Moura photovoltaics power station in Portugal and the 40 MW Waldpolnenz Solar Park in Germany are characteristic of the trend toward larger photovoltaics power station. Much larger ones are proposed, such as the 550 MW Topaz Solar Farm, and the 600 MW Rancho cielo Solar Farm. Solar power is a predictably intermittent energy sourse, meaning that whilst solar power is not available at all times, we can predict with a very good degree of accuracy when it will and will not be available. Some technologies, such as solar thermal concentrators have an element of thermal storage, such as molten salts. These store spare solar energy in the form of heat which is made available overnight or during periods that solar power is not available to produce electricity.

New Technology Telescope

Characteristics

It saw first light in 1989 and is owned by ESO. It is fitted with active optics (not to be confused with adaptive optics) allowing it to obtain an excellent image quality while only having a thin, lightweight mirror, kept in shape with a number of actuators beneath. The NTT was later cloned, resulting in the TNG.

Although other pre-existing telescopes such as the Nordic Optical Telescope had lightweight mirrors supported by actuators, the NTT is claimed to be the first telescope using full active optics. Its design as well as the design of its enclosure (the building protecting it) included many revolutionary features, from whence it was named. In particular, great care was taken to ensure a good ventilation of the telescope, and to avoid heat sources in around the telescope. Since its construction, the NTT has undergone several upgrades which continued to improve its quality. It was used as a real-life test bench for the engineering concepts and software used for the Very Large Telescope

The New Technology Telescope initially had the same problem as the Hubble Space telescope - the mirror was ground to the wrong shape due to a mis-calibrated null corrector. However, the active optics system of the NTT was able to correct that error without refiguring the mirror.

Credit card

A credit card is part of a sys

tem of payments named afte

r the small plastic card issued to users of the system. It is a card entitling its holder to buy goods and services based on the holder's promise to pay for these goods and services. The issuer of the card grants a line of credit to the consumer (or the user) from which the user can borrow money for payment to a merchant or as a cash advance to the user.

A credit card is different from a charge card, where a charge card requires the balance to be paid in full each month. In contrast, credit cards allow the consumers to 'revolve' their balance, at the cost of having interest charged. Most credit cards are issued by local banks or credit unions, and are the shape and size specified by the ISO/IEC 7810 standard as ID-1. This is defined as 85.60 × 53.98 mm in size.

How credit cards work

Credit cards are issued after an account has been approved by the credit provider, after which cardholders can use it to make purchases at merchants accepting that card.

When a purchase is made, the credit card user agrees to pay the card issuer. The cardholder indicates consent to pay by signing a receipt with a record of the card details and indicating the amount to be paid or by entering a personal identification number (PIN). Also, many merchants now accept verbal authorizations via telephone and electronic authorization using the Internet, known as a 'Card/Cardholder Not Present' (CNP) transaction.

Electronic verification systems allow merchants to verify that the card is valid and the credit card customer has sufficient credit to cover the purchase in a few seconds, allowing the verification to happen at time of purchase. The verification is performed using a credit card payment terminal or Point of Sale (POS) system with a communications link to the merchant's acquiring bank.. Data from the card is obtained from a magnetic strip or chip on the card; the latter system is in the United Kingdom and Ireland commonly known as Chip and Pin, but is more technically an EMVcard.

Other variations of verification systems are used by eCommerce merchants to determine if the user's account is valid and able to accept the charge. These will typically involve the cardholder providing additional information, such as the security code printed on the back of the card, or the address of the cardholder.

Each month, the credit card user is sent a statement indicating the purchases undertaken with the card, any outstanding fees, and the total amount owed. After receiving the statement, the cardholder may dispute any charges that he or she thinks are incorrect (see Fair credit Billing Act for details of the US regulations). Otherwise, the cardholder must pay a defined minimum proportion of the bill by a due date, or may choose to pay a higher amount up to the entire amount owed. The credit issuer charges interest on the amount owed if the balance is not paid in full (typically at a much higher rate than most other forms of debt). Some financial institutions can arrange for automatic payments to be deducted from the user's bank accounts, thus avoiding late payment altogether as long as the cardholder has sufficient funds.

First aid kit

A first aid kit is a collection of supplies and equipment for use in giving first aid. First aid kits may be made up of different contents depending on who has assembled the kit and for what purpose. It may also vary by region due to varying advice or legislation between governments or organisations.

The type of first aid facilities required in your workplace are determined by :

• the laws and regulation of the state or territory you live in;
• the type of industry you work in (industries such as mining may have specific industry regulations detailing specialised instructions);
• the type of hazards present in your workplace;
• the number of employees in your workplace;
• the number of different locations that your workplace is spread over;
• the proximity to local services (doctors, hospital, ambulance).

The first aid facility should meet the needs of your workplace. Facilities can include first aid kits or sick rooms.

If your workplace has rotating shifts then each shift should have it’s own first aid designated person. It is also best if your workplace has more than one designated first aid officer for any given shift to cover for workplace absences.

New Releases Film

Michael Jackson Returns in 'This Is It'

By Penelope Poulou
Washington
31 October 2009

Four months after Michael Jackson's sudden death, a film on his final days has opened around the globe. The movie called "This Is It" will play for two weeks only but may be extended.

The film, part documentary part musical concert, is based on Jackson's rehearsals for his London stage performances. They were scheduled for July but cancelled because of his untimely death.

Director, producer Kenny Ortega stitched together the 2-hour film from 120 hours of behind the scenes footage. "This is like a little backstage pass, a private peak into a creative process of a great genius," he says.

Jackson is electrifying. His moves are sharp. His musical sensibility flawless. His rhythm is so precise he's like a metronome.

Jackson was plagued by scandal, debt and rumors of failing health, and many questioned whether he could pull off a grand comeback.

But according to Ortega, Jackson envisioned his concerts as his crowning achievement, the spectacle to end all spectacles. "We had new technology with video, costuming, lighting with sound, with pyrotechnics. I came to know very quickly that Michael liked things hotter, bigger, louder," he says.

The film shows Jackson in top shape. Immersed in his work, he was the creative spirit behind a supercharged production showcasing the hits of a lifetime.

People waited in line for hours, in the rain, outside a Washington DC movie theater, hoping for tickets to the only screening before the sold-out premiere.

They were not disappointed.

On its opening day worldwide, the film topped the box office, raking in $66.6 million. But it's not only about money. The movie reaffirms Jackson's genius and gives a glimpse of his comeback, had there been one. Fan or no fan, one leaves the theater heartbroken at the loss.
