B.C.-Canada Place officially closes doors

Monday, March 20, 2006 marks the official close of British Columbia-Canada Place, one of the most successful attractions of the 2006 Torino Olympic and Paralympic Winter Games.

Over the course of the 2006 Olympic and Paralympic Winter Games, British Columbia-Canada Place drew more than 100,000 visitors and journalists. These visitors were able to experience first hand the province’s culture, heritage, natural beauty and bustling cities. Also, more than 80 British Columbia businesses were able to connect with an international audience and showcase some of B.C.’s best products and services.

B.C.-Canada Place will be a legacy to the people of Torino. The official transfer took place in a ceremony yesterday, with Torino Mayor Sergio Chiamparino accepting a ceremonial key to the building.

“This generous gift from British Columbia will be a constant reminder of our friends in Canada and the celebrations that took place in our city during the 2006 Winter Games,” says Mayor Chiamparino. “We are honored to have this permanent B.C. presence in our city.”

Kent Kickin' Mini-Scooters

Kent is recalling about 90,000 scooters. The scooter handles can unexpectedly come out of the steering column if the clamp holding them in is not tight, causing the rider to lose control, fall and possibly suffer injuries.
Kent has received four reports of the handles coming out, resulting in four children suffering injuries, including broken arms, a broken wrist, bruises, abrasions and a cracked tooth.
These are Kickin' Mini-Scooters made of chrome-plated steel. A vertical decal on the steering column reads "KICKIN' MINI SCOOTER." The scooter's black plastic platform measures about 15 inches long, and it has 4-inch translucent in-line style wheels. "KENT" and "MADE IN CHINA" are written on the lower part of the steering column. The scooters were sold with black backpacks embroidered in white with the word "Kickin."
Toys R us stores nationwide sold the Kent scooters from May 2000 through September 2000 for about $60.
Consumers should stop riding these Kent scooters immediately, and call Kent International to receive a free replacement handlebar with pins to secure the handlebars. For more information, call Kent International at (800) 451-KENT (5368) between 8 a.m. and 5 p.m. ET Monday through Friday.
Kent has sold other models to Toys R Us such as the Street Craze, the Street Racer and Scoot that are NOT part of this recall. Scooters that Kent sold to Wal Mart, Meijer's, Target and AAFES are also NOT part of this recall.

Trampoline Safety Alert

The U. S. Consumer Product Safety Commission (CPSC) wants you and your family to be safe when using trampolines. The CPSC estimates that in 2001 there were 91,870 hospital emergency room-treated injuries associated with trampolines. About 93 percent of the victims were under 15 years of age, and 11 percent were under 5 years of age. Since 1990, CPSC has received reports of 6 deaths of children under age 15 involving trampolines. Injuries and deaths were caused by:

* Colliding with another person on the trampoline.
* Landing improperly while jumping or doing stunts on the trampoline.
* Falling or jumping off the trampoline.
* Falling on the trampoline springs or frame.
Most of the trampolines associated with injuries were at private homes.
Here are the steps you can take to help prevent serious trampoline injuries, especially paralysis, fractures, sprains, and bruises:

* Allow only one person on the trampoline at a time.
* Do not attempt or allow somersaults because landing on the head or neck can cause paralysis.
* Do not use the trampoline without shock-absorbing pads that completely cover its springs, hooks, and frame.
* Place the trampoline away from structures, trees, and other play areas.
* No child under 6 years of age should use a full-size trampoline. Do not use a ladder with the trampoline because it provides unsupervised access by small children.
* Always supervise children who use a trampoline.
* Trampoline enclosures can help prevent injuries from falls off trampolines.

Accumulator

In a computer CPU, an accumulator is a register in which intermediary arithmetic and logic results are stored. Without a register like an accumulator, it would be necessary to write the result of each calculation (addition, multiplication, shift, etc.) to main memory, possibly only to be read right back again for use in the next operation. Access to main memory is slower than access to a register like the accumulator because the technology used for the huge main memory is slower (but cheaper) than that used for a register.

The canonical example for accumulator use is adding a list of numbers. The accumulator is initially set to zero, then each number in spin is added to the value in the accumulator. Only when all numbers have been added is the result seized in the accumulator written to main memory or to another, non-accumulator, CPU register.

Semiconductor

A semiconductor is a solid material that has electrical conductivity in between that of a conductor and that of an insulator; it can vary over that wide range either permanently or dynamically. Semiconductors are tremendously important in technology. Semiconductor devices, electronic components made of semiconductor materials, are essential in modern electrical devices. Examples range from computers to cellular phones to digital audio players. Silicon is used to create most semiconductors commercially, but dozens of other materials are used as well.

Professional engineer

Engineers typically require a type of professional certification, such as satisfying certain education requirements and passing an examination to become a professional engineer. These certifications are usually nationally regulated and registered, but there are also cases of self-governing bodies, such as the Canadian Association of Professional Engineers. In many cases, carrying the title of "Professional Engineer" is legally protected.

As BME is an emerging field, professional certifications are not as standard and uniform as they are for other engineering fields. For example, the Fundamentals of Engineering exam in the U.S. does not include a biomedical engineering section, though it does cover biology. Biomedical engineers often simply possess a university degree as their qualification. However, some countries, such as Australia, do regulate biomedical engineers, however registration is typically only recommended and not required.

A general view on Mainframe computer

Mainframes (often colloquially known to as big iron) are large and "expensive" computers used largely by government institutions and large companies for mission important applications, typically mass data processing such as censuses, ERP, industry/consumer statistics, and financial transaction processing.

The word originated during the near the beginning 1970s with the introduction of smaller, less difficult computers for example the DEC PDP-8 and PDP-11 series, which became recognized as minicomputers or just minis. The industry/users then coined the word "mainframe" to describe bigger, earlier types (before known simply as "computers").

Mainframes often maintain thousands of simultaneous users who gain right of entry through "dumb" terminals or terminal emulation. Early mainframes either supported this timesharing mode or operated in batch mode where users had no straight access to the computing service, it exclusively providing back office functions. At this time mainframes were so called for the reason that of their very substantial size and requirements for specialized HVAC and electrical power. Nowadays mainframes support right of entry via any user interface, including the Web. Blade servers rather than mainframes are currently increasingly requiring "exotic" cooling technologies.

The real facts about Uranus

Uranus is the seventh planet from the Sun and the third biggest (by diameter). Uranus is bigger in diameter but smaller in mass than Neptune. Uranus is composed mainly of rock and various ices, with only about 15% hydrogen and a little helium (in compare to Jupiter and Saturn which are mostly hydrogen). Uranus (and Neptune) is in numerous ways alike to the cores of Jupiter and Saturn minus the huge liquid metallic hydrogen envelope. It appears that Uranus does not have a stony core like Jupiter and Saturn but rather that its material is more or less consistently distributed.

Like the other gas planets, Uranus has bands of clouds that carry around rapidly. But they are very faint, visible only with radical image improvement of the Voyager 2 pictures (right). Recent observations with HST (left) show bigger and more pronounced streaks. Additional HST observations show even more activity. Uranus is no longer the ordinary boring planet that Voyager saw! It now seems understandable that the differences are due to seasonal effects since the Sun is now at lesser Uranian latitude which may because more pronounced day/night weather effects. By 2007 the Sun will be unswervingly over Uranus's equator.

Like the additional gas planets, Uranus has rings. Like Jupiter's, they are extremely dark but like Saturn's they are composed of quite large particles ranging up to 10 meters in diameter additionally to fine dust. There are 11 recognized rings, all very faint; the brightest is identified as the Epsilon ring. The Uranian rings were the first after Saturn's to be discovered. This was of great importance since we now know that rings are a common feature of planets, not a peculiarity of Saturn alone. Uranus' fascinating field is odd in that it is not centered on the center of the planet and is tilted almost 60 degrees with respect to the axis of rotary motion. It is almost certainly generated by motion at relatively shallow depths within Uranus.

The real facts about Neptune

Neptune is the eighth planet from the Sun and the fourth largest (by diameter) of the planet. Neptune is smaller in diameter but bigger in mass than Uranus. Neptune's composition is almost certainly alike to Uranus': various "ices" and rock with about 15% hydrogen and a little helium. Like Uranus, but unlike Jupiter and Saturn, it can not have a distinct internal layering but rather to be more or less uniform in composition. But there is most expected a small core (about the mass of the Earth) of rock-strewn material. Its atmosphere is generally hydrogen and helium with a minute amount of methane.

Neptune's blue color is mainly the result of absorption of red light by methane in the atmosphere but there is a number of additional as-yet-unidentified chromophore which gives the clouds their rich blue tint. Like Jupiter and Saturn, Neptune has an inner heat source -- it radiates more than, twice as much energy as it receives from the Sun.

Neptune also has rings. Earth-based observations showed just faint arcs rather than complete rings, but Voyager 2's images showed them to be entire rings with bright clumps. One of the rings looks to have a curious twisted structure (right). Like Uranus and Jupiter, Neptune's rings are extremely dark but their composition is unknown.

Neptune's rings have been noted names: the outermost is Adams (which contains three important arcs now named Liberty, Equality and Fraternity), next is an unnamed ring co-orbital with Galatea, then Leverrier (whose outer extensions are called Lassell and Arago), and lastly the faint but broad Galle. Neptune's magnetic field is, like Uranus', oddly oriented and most likely generated by motions of conductive material (probably water) in its middle layers.

Cookie

In the United States and Canada, a cookie is a tiny, round, flat cake. In most English-speaking countries outer North America, the most common word for this is biscuit; in many regions both terms are used, while in others the two words have diverse meanings—a cookie is a bun in Scotland, while in the United States a biscuit is a kind of quick bread not unlike a scone.

Cookies can be baked until crisp or just long enough that they stay soft. Depending on the kind of cookie, some cookies are not cooked at all. Cookies are made in a broad variety of styles, using an array of ingredients including sugars, spices, chocolate, butter, peanut butter, nuts or dried fruits. The smoothness of the cookie may depend on how long it is baked.

Mainframes

Mainframes (often colloquially referred to as big iron) are huge and expensive computers used mainly by government institutions and large companies for mission critical applications, usually bulk data processing such as censuses, industry/consumer statistics, ERP, and financial transaction processing.
The term originated during the early 1970s with the introduction of smaller, fewer complex computers such as the DEC PDP-8 and PDP-11 series, which became known as minicomputers or just minis. The industry/users then coined the term "mainframe" to describe bigger, earlier types (previously known simply as "computers").

Traffic Light

A traffic light or traffic signal is a signalling device positioned at a road junction or pedestrian crossing to indicate when it is safe to drive, ride or walk, using a universal color code.Traffic lights for usual vehicles or pedestrians always have two main lights, a red one that means stop and a green one that means go. Generally, the red light contains some orange in its hue, and the green light contains some blue, to provide some support for people with red-green color blindness. In most countries there is also a yellow (or amber) light, which when on and not flashing means stop if able to do so securely. In some systems, a flashing amber means that a motorist may go in advance with care if the road is clear, giving way to pedestrians and to other road vehicles that may have precedence. A flashing red effectively means the same as a regular stop sign. There may be additional lights (usually a green arrow or "filter") to allow turns (called a lead light in the U.S., because it is usually leading the main green light).

Goshawk

The Goshawk is an average large bird of quarry in the family Accipitridae which also includes many other diurnal raptors such as eagles, buzzards and harriers.

It is an extensive species all through the moderate parts of the northern hemisphere. In North America it is named as the Northern Goshawk. It is typically inhabitant, but birds from colder regions of north Asia and Canada journey south for the winter.


Goshawk in flight this species nests in trees, building a new nest each year. It hunts birds and mammals in woodland, relying on revelation as it flies from a perch or hedge-hops to catch its quarry ignorant. Animals as large as hares and Pheasant are taken. Its call is a ferocious screech. Many older goshawks reject to attack hares, if it was earlier seriously kicked by a hare which it tried to catch.

This bird is a raptor with short large wings and a long tail, both adaptations to maneuvering through trees. The male is blue-grey above and banned grey below, 49-56 cm long with a 93-105 cm wingspan. The much larger female is 58-64 cm long with a 108-127 cm wingspan, slate grey above grey below. The youthful is brown above and barred brown below. The flight is a characteristic "slow flap – slow flap – straight glide".

In Eurasia, the male is confusable with a female Sparrow hawk, but is superior, much bulkier and has moderately longer wings. In spring, he has an impressive roller-coaster display, and this is the best time to see this enigmatic forest bird.

Tumor

Tumor or tumour is an irregular growth or mass of tissue. A tumor can be either malignant or benign. Almost all tumors are examples of neoplasia, although certain developmental malformations or inflammatory masses may occasionally be referred to as tumors.

Neoplastic tumors are caused by mutations in DNA of cells, which interfere with a cell's capability to regulate and limit cell division. An accumulation of mutations is needed for a tumor to emerge. Mutations that activate oncogenes or repress tumor suppressor genes can eventually lead to tumors. Cells have mechanisms that repair DNA and other mechanisms that cause the cell to destroy itself by apoptosis if DNA damage gets too severe. Mutations that repress the genes for these mechanisms can also ultimately guide to cancer. A mutation in one oncogene or one tumor repressor gene is usually not enough for a tumor to occur. A combination of a number of mutations is essential.

Microcomputer

A microcomputer is mainly often taken to mean a computer with a microprocessor (µP) as its CPU. Another general characteristic of these computers is that they take up physically small amounts of space.Desktop computers, video game consoles, laptop computers, tablet PCs, and a lot of handheld devices may all be considered examples of microcomputers.Most microcomputers serve only a single user at a time, but some, in the form of PCs and workstations running e.g. a UNIX(-like) operating system, may cater to a number of users concurrently. The µP does the majority of the job of calculating on and manipulating data that all computers do.

Salad

Salad is a light meal — or, as part of a larger meal, much more of an taster — consisting of mixed vegetables (usually including at least one leaf vegetable) or fruit, frequently with a dressing or sauce, occasionally nuts and sometimes with the addition of meat, fish or cheese. It is generally seen as a healthy dish, although not always low in calories, salt, sugar, or fat because of the dressing that is often added.The word "salad" comes from the French salade of the same meaning, which in twist is from the Latin salata, "salty", from sal, "salt".

Traffic Claming

Traffic calming is a set of strategies used by urban planners and traffic engineers which aims to slow down traffic and get better safety for pedestrians and bicyclists, although some of these features can also be hazardous to cyclists. It is now comparatively common in Europe, especially Northern Europe; less so in North America.Traffic calming has conventionally been justified on the grounds of pedestrian safety and reduction of noise and local air pollution which are side effects of the traffic. However, it has become more and more apparent that streets have many social and recreational functions which are severely impaired by fast car traffic. For much of the twentieth century, streets were designed by engineers who were charged only with ensuring traffic flow and not with development other functions of streets. The rationale for traffic reassuring is now broadening to include designing for these functions.

Lighthouse of Alexandria

The Pharos of Alexandria was a big tower built in the 3rd century BC (between 285 and 247 BC) on the island of Pharos in Alexandria, Egypt to give out as that port's landmark, and later, its lighthouse.

With a height variously estimated at between 115 and 150 meters (383 - 450 ft) it was among the tallest man-made structures on Earth for many centuries, and was recognized as one of the Seven Wonders of the World by Antipater of Sidon. It was the third tallest building after the two Great Pyramids (of Khufu and Khafra) for its whole life. Some scientists approximate a much taller height exceeding 180 metres that would make the tower the tallest building up to the 14th century.
