Counter-Strike (CS) is a tactical first-person shooter video game which originated from a Half-Life modification.The game is currently the most played Half-Life modification in terms of players, according to GameSpy.

Counter-Strike is a first-person shooter in which players join either the terrorist or counter-terrorist team (or become a spectator). Each team attempts to complete their mission objective and/or eliminate the opposing team. Each round starts with the two teams spawning simultaneously, usually at opposite ends of the map from each other. A player can choose to play as one of eight different default character models (four for each side, although Counter-Strike: Condition Zero added two extra models, bringing the total to ten). Players are generally given a few seconds before the round begins (known as “freeze time”) to prepare and buy equipment, during which they cannot attack or walk/move (a player can still take damage, having the player drop from a certain height during freeze time was the only way somebody could control the players starting “HP”). They can return to the buy area within a set amount of time to buy more equipment (some custom maps included neutral “buy zones” that could be used by both teams). Once the round has ended, surviving players retain their equipment for use in the next round; players who were killed begin the next round with the basic default starting equipment.

After years of controversy over whether cellphone radiation might cause cancer, scientists have reached the startling conclusion that it might actually cure Alzheimer’s disease. Young mice exposed to long-term radiation equivalent to human cellphone use of a couple of hours a day were protected from Alzheimer’s, and memory function was restored in old mice already afflicted.

Despite long-standing concerns about the health effects of cellphones, a new study suggests that radiation from the devices may actually have a beneficial effect when it comes to Alzheimer’s disease.

Specifically, long-term exposure to the electromagnetic waves associated with cellphone use may actually protect against — and even reverse — Alzheimer’s, according to a study led by University of South Florida researchers at the Florida Alzheimer’s Disease Research Center (ADRC) and published Wednesday in the Journal of Alzheimer’s Disease.

“It surprised us to find that cellphone exposure, begun in early adulthood, protects the memory of mice otherwise destined to develop Alzheimer’s symptoms,” said lead author Gary Arendash, a research professor at the Florida ADRC. “It was even more astonishing that the electromagnetic waves generated by cellphones actually reversed memory impairment in old Alzheimer’s mice.”
Beta Amyloid
The study involved 96 mice, most of which were genetically altered to develop brain deposits of the harmful protein beta amyloid along with memory problems mimicking Alzheimer’s disease as they aged.

The sticky brain plaques formed by the abnormal accumulation of beta amyloid are a hallmark of Alzheimer’s and are the focus of most treatments for the disease.

Some mice were “non-demented” — that is, they were given no genetic predisposition for Alzheimer’s — so researchers could test the effects of electromagnetic waves on normal memory as well.
Brain Deposits Erased

Both the Alzheimer’s and normal mice were exposed to the electromagnetic field generated by standard cellphone use for two one-hour periods each day for seven to nine months.

To accomplish that exposure, the mice’s cages were arranged around a centrally located antenna generating the cellphone signal. Each animal was housed the same distance from the antenna and exposed to electromagnetic waves typically emitted by a cellphone pressed against a human head.

What the researchers found, ultimately, was that exposing old Alzheimer’s mice to electromagnetic waves generated by cellphones actually erased brain deposits of the harmful beta amyloid. In addition, among the younger Alzheimer’s mice, it prevented the protein’s build-up.
Memory Impairment Disappeared

Not only that, but in the genetically programmed mice who began cellphone exposure as young adults — before signs of memory impairment were apparent — cognitive ability was protected. When older Alzheimer’s mice who had already exhibited memory problems were exposed to the electromagnetic waves, meanwhile, their memory impairment disappeared.

Months of cellphone exposure even boosted the memories of normal mice to above-normal levels, the study found.

Based on the results in mice, the researchers concluded that electromagnetic field exposure could be an effective, noninvasive and drug-free way to prevent and treat Alzheimer’s disease in humans. They are currently evaluating whether different sets of electromagnetic frequencies and strengths will produce more rapid and even greater cognitive benefits than those observed in their current study.
Cellphone Danger?

“This is an interesting though very preliminary study,” said William Thies, chief medical and scientific officer for the Alzheimer’s Association.

“The significance of the findings is unclear,” Thies added. “What is clear is that much stronger evidence exists that says using your cellphone in your car is dangerous and potentially harmful than for anything in this article.”

Consumers should certainly not try to “self medicate” by spending more time on their cellphones, Thies asserted.

“That said, this idea deserves further study,” he said. “The unexpected effects observed are potentially interesting and justify further study.”
‘Users Are Not Very Concerned’

Recent studies have both supported and refuted the notion that cellphones are dangerous for human health.

How concerned consumers are, of course, is another question.

“I can infer that users are not very concerned, because the number of cellphone users keeps on growing,” In-Stat analyst Allen Nogee told TechNewsWorld. “I have heard of some users switching to Bluetooth, whereby they can keep the phone further away from their head, but I’m not sure if one’s better than the other.”
‘People Will Chuckle About It’

Indeed, “health concerns about cellular have always been a low-level concern,” agreed Chris Ambrosio, executive director of wireless within the wireless practice at Strategy Analytics.

“People are concerned about it,” he told TechNewsWorld, “but not enough to stop talking on their phones.”

The issue, in fact, is in some ways comparable to global warming, Ambrosio suggested: “It’s one of those issues where you’ll get support on both sides, but you can never definitively prove it either way.”

The current study, then, “is an interesting headline,” he concluded, but “people will probably chuckle about it and go on their way.”

“Less than 4 months after releasing the first DX11 desktop graphics card, AMD has followed up with a whole lineup of mobile graphics processors based on the same architecture. The new Mobility Radeon HD 5000 lineup includes four different series of GPUs designed to serve everything from high-end gaming notebooks to mainstream thin-and-light systems. AMD has based these processors on the same silicon chips as its desktop Radeon HD 5000-series graphics cards, so performance shouldn’t disappoint. The company also intends to follow Nvidia’s lead by offering notebook graphics drivers directly from its website, as opposed to relying on laptop vendors to provide updates.”

New navigation devices lead a group of new mobile phones expected for the Middle East and Africa

At a launch event held in the Egyptian capital Cairo, Nokia has unveiled the latest device in the company’s range focused on mapping and navigation, the Nokia 2710 Navigation Edition. The new arrival is GPS enabled and pre-loaded with Nokia Maps, making it the most affordable GPS device in Nokia’s broad portfolio.
2710
It will be available in the second quarter of 2010 estimated price is going to be Rs. 14,000 to Rs. 16,000

Due to the accessible and affordable pricing, the new device is expected to be popular in the developed and developing world alike. The handset has been optimized for use across urban environments, small towns, as well as rural areas – incorporating straight line pedestrian navigation with the assistance of an integrated digital compass. Straight line technology allows people a comprehensive range of mobile navigation capabilities for use across pathless terrains. Other features include turn-by-turn driving navigation with full voice guidance, which recalibrates routes depending on the driver’s current GPS location, all accessed with a convenient dedicated navigation key.

“There is a clear trend to provide navigation, mapping and other location based services to mobile phones, and having mapping and location based services integrated in one single mobile device rather than buying two devices is a great benefit” says Alex Lambeek, Vice President, Mobile Phones, Nokia. “Of course, when bringing this experience to new people, new prices and new countries, you need to make sure the experience is optimized and locally relevant. With Nokia Maps, Nokia provides the broadest navigation coverage of any competitor and we continue to add new countries all the time.”

As the cost and availability of data connections is sometimes limited, relevant maps are included on the device to save cost and make sure that just because you don’t have an Internet connection, your device isn’t rendered useless.

At the same event, Nokia also showcased its recently announced range of new affordable and easy-to-use mobile phones in the Nokia 1280, Nokia 1616, Nokia 1800, Nokia 2220 slide and Nokia 2690. Starting at an estimated price of €20 before taxes and subsidies, the new range is ideal for consumers the world over.

“We believe in offering a broad portfolio that caters to a wide variety of needs. This full device range will serve a broad spectrum of people, empower entrepreneurs and provide consumers with knowledge, entertainment and the ability to connect with friends and family,” continues Lambeek. “Services like Nokia Life Tools and Ovi Mail offer consumers a whole new range of opportunities, including getting their first digital identity, without the need for a PC. With our longstanding commitment to emerging markets, people in rural areas will be able to access information which helps them make informed decisions and has a positive and lasting impact on their lives.”

1.Let your PC boot up completely before opening any applications.
2.Refresh the desktop after closing any application. This will remove any unused files from the RAM.
3.Do not set very large file size images as your wallpaper. Do not keep a wallpaper at all if your PC is low on RAM (less than 64 MB).
4.Do not clutter your Desktop with a lot of shortcuts. Each shortcut on the desktop uses up to 500 bytes of RAM
5.Empty the recycle bin regularly. The files are not really deleted from your hard drive until you empty the recycle bin.

6.Delete the temporary internet files regularly.
7.Defragment your hard drive once every two months. This will free up a lot of space on your hard drive and rearrange the files so that your applications run faster.
8.Always make two partitions in your hard drive. Install all large Softwares (like PSP, Photoshop, 3DS Max etc) in the second partition. Windows uses all the available empty space in C drive as virtual memory when your Computer RAM is full. Keep the C Drive as empty as possible.
9.When installing new Softwares disable the option of having a tray icon. The tray icons use up available RAM, and also slow down the booting of your PC. Also disable the option of starting the application automatically when the PC boots. You can disable these options later on also from the Tools or preferences menu in your application.
10. Protect your PC from dust. Dust causes the CPU cooling fan to jam and slow down thereby gradually heating your CPU and affecting the processing speed. Use compressed air to blow out any dust from the CPU. Never use vacuum.
RAM IS THE WORKING AREA (DESKTOP) OF THE CPU, KEEP IT AS EMPTY AND UNCLUTTERED AS POSSIBLE!
