Can you Recognize Carbon Monoxide Poisoning?

Several years ago, a family including five children and their parents was enjoying a holiday in the American state of California, near the Pacific Ocean.

The family was spending the weekend in a camper. A camper is a small shelter carried in the back of a truck. People can sleep in it for a few days.

The weather turned cold the second night the family stayed along the Pacific coast. The camper did not have any heating equipment to warm the space while family members slept.

Someone decided to heat the area by placing a charcoal grill inside the camper. The device burned a wood product, charcoal. The fire immediately warmed the family members. They all went to sleep.

The next day, other people found the family. The parents and their five children had died in their sleep. They died because they did not know that burning wood products creates a deadly gas ?carbon monoxide.

Carbon monoxide poisoning is known as a silent killer. The California family went to sleep in their warm camper and never woke up.

Carbon monoxide poisoning causes death and injuries around the world. The poison gas has been a problem since people first began burning fuels to cook food or to create heat.

This gas is a problem in all parts of the world that experience cold weather. Last year, America's Centers for Disease Control studied deaths linked to carbon monoxide poisoning. It found that the average number of carbon monoxide deaths in the United States is greatest in the month of January.

The study also found that carbon monoxide kills about five hundred people in the United States each year. And, the report said, about fifteen thousand people are taken to hospital emergency rooms for treatment of health problems linked to the gas.

Carbon monoxide is called the silent killer because people do not know it is in the air. The gas has no color. It has no taste. It has no smell. It does not cause burning eyes. And it does not cause people to cough.

Yet carbon monoxide gas is very deadly. It steals the body's ability to use oxygen.

Carbon monoxide decreases the ability of the blood to carry oxygen to body tissues. It does this by linking with the blood. When the gas links with the blood, the blood is no longer able to carry oxygen to the tissues that need it. Damage to the body can begin very quickly from large amounts of carbon monoxide.

How quickly this can happen depends on the length of time a person is breathing the gas and the amount of the gas he or she breathes in.

Carbon monoxide poisoning has warning signs. But people have to be awake to recognize them. Small amounts of the gas will cause a person's head to hurt. He or she may begin to feel tired. The victim's stomach may feel sick. The room may appear to be turning around. The person may have trouble thinking clearly.

People develop severe head pain as the amount of gas continues to enter their blood. They will begin to feel very tired and sleepy. They may have terrible stomach pains.

Carbon monoxide is measured in parts per million in a normal atmosphere. Breathing in two hundred parts per million of carbon monoxide will cause the first signs of poisoning. It will result in head pain, stomach problems and a feeling of tiredness after two to three hours.

A level of eight hundred parts per million will cause a person to lose consciousness. Victims will not know what is taking place around them. This will happen within two hours of breathing in this amount of carbon monoxide. Twelve thousand parts per million of the gas will cause death in one to three minutes.

Medical experts say carbon monoxide affects people differently. For example, a small child will experience health problems or die much quicker than an adult will. The general health of the person or his or her age can also be important.

An older adult with health problems may suffer the effects of carbon monoxide more quickly than a younger person with no health problems. People with heart disease may suffer chest pains. They may begin to have trouble breathing.

Carbon monoxide does not always cause death. But it can cause many medical problems. Breathing low amounts of the gas for long periods of time can lead to permanent damage in the heart, lungs or brain.

Medical experts say small amounts of carbon monoxide over a long period of time can greatly harm an unborn baby.

What causes carbon monoxide gas? Any device that burns fuels such as coal, oil or wood can create the gas.

Water heaters that burn natural gas create carbon monoxide. Fireplaces and stoves that burn wood create the gas. Natural gas stoves and gas dryers or charcoal grills also create carbon monoxide. Automobiles create it. Any device that burns fossil fuels like coal, oil, wood, gasoline, kerosene or propane will produce carbon monoxide.

Experts agree that the leading cause of carbon monoxide poisoning is damaged equipment that burns these fuels. They say many people die or are injured by the gas because they do not use these devices correctly.

Experts say any device used to heat a home should be inspected to make sure it is working correctly. And, no cooking equipment like a charcoal grill should ever be used to heat an inside area.

Carbon monoxide gas is created by fuel burning devices because not all of the fuel is burned. Most devices used for home heating have a way to expel the gas from the home. For example, a fireplace has a chimney. Natural gas stoves or gas water heaters are usually connected to a device that safely expels the gas from the home. An automobile has a system for expelling unburned gasoline under and behind the vehicle.

Anyone who uses a device that burns fossil fuel must inspect the equipment carefully to reduce chances of carbon monoxide escaping. Companies that produce the devices usually provide directions about using the device correctly. These directions should be read and understood before using any equipment that burns fuel inside a home.

You can do a number of things to protect yourself from the effects of carbon monoxide. First, immediately leave the area if you recognize the signs of carbon monoxide poisoning in yourself or others.

Seek emergency medical services after you leave the area where you suspect the gas might be. Usually the treatment for carbon monoxide poisoning involves breathing in large amounts of oxygen. However, a doctor will know the best method to treat the effects of such poisoning.

Carbon monoxide does not quickly leave the body, even after treatment has begun. It can take several hours before the gas disappears.

If you suspect carbon monoxide is a problem in your home, you might try calling your local fire department. Many firefighters have the necessary equipment to find or identify the gas.

Carbon monoxide detectors
In many countries, it is possible to buy and use a special device that will warn when harmful levels of carbon monoxide are in the area. These devices can be linked to a home's electric system. Others work with electric batteries. Experts say these special devices should be placed near sleeping areas in the home.

Muslims protest cartoons of the Prophet in Afghanistan turned into a violent anti-US riots

In an interview with Britain's Daily Telegraph, EU Justice and Security Commissioner Franco Frattini said the charter would encourage the media to show "prudence" when covering religion.
An Afghan protester shouts slogans as he marches through the streets of Kabul during a demonstration in Kabul, Afghanistan, Wednesday, Feb. 8, 2006.

"The press will give the Muslim world the message: We are aware of the consequences of exercising the right of free expression," he told the newspaper. "We can and we are ready to self-regulate that right."

His proposed voluntary code would urge the media to respect all religious sensibilities but would not offer privileged status to any one faith.

The cartoons, which first appeared in a Danish newspaper last September before being reprinted across Europe, sparked a wave of protests around the world. Newspapers which have published them say they are exercising their right to freedom of speech, while critics say the cartoons are deliberately offensive. Depicting the Prophet Mohammad is prohibited by Islam. Frattini, a former Italian foreign minister, said millions of Muslims in Europe felt "humiliated" by the cartoons.
The EU's foreign policy chief Javier Solana is to travel to Arab and Muslim countries in an attempt to calm the anger caused by the cartoons.
The code would be drawn up by the European Commission, the EU executive body, and European media outlets, he said. It would not have legal status.

Extra! Extra! Read all about it! That street corner cry of yesteryear is resonating at some European publications that have enjoyed a boom in sales and Web traffic after printing caricatures of the Prophet Muhammad that have stoked outrage across the Islamic world.
Denmark's biggest-circulation broadsheet, Jyllands-Posten, triggered the controversy in September by publishing 12 cartoons of the prophet, including one showing his turban as a bomb. Its weekday circulation of about 154,000 hasn't moved much.
But for newspapers in France and Norway that reprinted the drawings with much international ado, the caricatures have become a profile boost and tonic for lackluster sales.
If there's a lesson, it's an old one: Controversy sells.
Mohamed Bechari, a vice president at the French Council of the Muslim Faith, France's largest Islamic organization, said he thinks French readers are buying up the newspapers out of "curiosity" — not anti-Arab or anti-Muslim feeling.
"Here's some advice to those newspapers today facing ruin, bankruptcy or collapse: All you need do is insult Muslims and Islam, and sales will get hot as blazes," he told The Associated Press at a Paris conference Thursday on promoting dialogue between the West and the Muslim world, convened in response to the furor over the drawings.
Demonstrators in Syria, Lebanon and Iran have attacked Western embassies. Protests and boycotts of Danish goods erupted in numerous Arab and Islamic countries. Three days of riots across Afghanistan left 11 people dead.

Fighter Jet Crashes in California Desert

The F-22 Raptor crashed 35 miles northeast of Edwards Air Force Base, Pentagon spokesman Gary Strassburg said. He had no information about the area where the jet crashed.Rescue crews were en route and the status of the pilot was unknown, said Air Force Maj. David Small at the Pentagon.

Small said the jet, assigned to the 411th Flight Test Squadron of Edwards' 412th Test Wing, was on a test mission but he did not know its nature. The crash occurred at midmorning.Call to the base public affairs phone numbers were answered by recording machines.The radar-evading F-22s each cost $140 million and are designed for air dominance. The warplanes can carry air-to-air missiles but are capable of ground attack as well.The $65 billion F-22 program is embattled, with some opponents contending that a different warplane under development, the F-35 Joint Strike Fighter, is more versatile and less costly at $80 million per plane.

EDWARDS AIR FORCE BASE, Calif. (March 25) - One of the Air Force's top-of-the-line F-22 fighter jets crashed Wednesday in the high desert of Southern California. There was no immediate word on whether the pilot ejected.


F-22s were grounded for two weeks after one crashed at Nellis Air Force Base in Nevada in December 2004. They were cleared again to fly after a review, and an Air Force statement at the time said officials were "highly confident in the design, testing and development" of the aircraft. The pilot in that crash successfully ejected.
The U.S. is committed to 183 F-22s, down from the original plan laid out in the 1980s to build 750.

The F-22 is able to fly at supersonic speeds without using afterburners. That allows it to reach and stay in a battlespace faster and longer without being easily detected.The fighter, powered by two Pratt & Whitney engines, is 62 feet long, has a wingspan of 44 1/2 feet and is flown by a single pilot.
Lockheed is trying to convince the Pentagon to buy as many as 20 more F-22s. The military is expected to signal its intentions when the 2010 Defense Department budget is released next month.
Its prime contractor, Lockheed Martin Corp., says there are 95,000 jobs at 1,000 companies connected to the F-22.A spokesman for Bethesda, Md.-based Lockheed Martin referred all calls about the crash to the Air Force.

A new Cell processor in future laptop

The Toshiba Qosmio G40 notebook will sport a SpursEngine SE1000 chip based on the Cell Broadband Engine, which is also used in the Sony PlayStation 3.

Toshiba is expected to release a notebook PC this year that uses a chip based on the Cell processor, the same chip used in Sony's PlayStation.

The Cell Broadband Engine is a multi-core chip architecture jointly developed by IBM, Sony, and Toshiba. It is derived from IBM's Power Architecture, which was once used in Apple notebooks and desktops. Today, IBM uses the Cell processor in a line of blade servers.
Samples of the SE1000 chip began shipping from Toshiba on April 8. Toshiba has said it expects sales of 6 million units within the first three years.

The SpursEngine can do high-definition video encoding and decoding of MPEG-2 and H.264 streams, among other capabilities. The four processing elements inside the chip have a clock frequency of 1.5GHz, while boasting a relatively low power envelope of 10 to 20 watts.
Some other features of the SpursEngine: Its multimedia engine can deliver up to 48 GFlops (billion Floating point operations per second) or 12GFlops per processing element. Every element has 256KB of integrated memory. The circuit board (photo) supports a PCI-Express Base Specification Revision 1.1.
Toshiba also plans to release a TV with the Cell processor.

Laptop AC Adapter

Some of the most helpful items that can enhance computer use are surge protectors and security cables. Surge protectors are an important extra that will keep any notebook safe as well as the internal data. Electrical surges can destroy data and the motherboard while traveling and put a user in dire straights if he or she must use a computer for work or other necessary activities. Laptop accessories such as surge protectors are made especially to fit notebooks and are very portable. Many are made with retractable cords and smaller plugs that can fit just about anywhere. They do not weight very much and are easy to pack within a portable computer suitcase. Another important item is security cables that can be used to keep a computer locked when not in use. Some are made of unbreakable material such as titanium that adds tamper-free peace of mind.There are many laptop accessories available to make using a notebook easy while on the road, in school or traveling from job to job. Items such as surge protectors, security cables, screen protectors, coolant fans and laptop ac adapter products are among the most popular items that users purchase to enhance their working experience. A consumer that purchases a notebook computer might as well plan on spending a little extra cash on one or two of the many extras that are produced especially for their particular model. While some consumers purchase only what is needed, others have found it an almost hobby to get the latest extra that is marketed as soon as it hits the stores. Digital equipment enhancements continue to top the consumer choices among purchases each year and computer items are a leading area for most stores.Other types of adapters are also helpful to notebook users such as a PowerBook G4 (1GHz/867MHz) Most laptops do not have enough USB ports when there are lots of laptop accessories in use such as a wireless mouse, keyboard and other cable hookups. A PowerBook G4 (1GHz/867MHz) offers several ports that can be connected through one connection to a single USB on a notebook. This expands port capabilities and can offer a large number of ports to accommodate the many possible items for maximum notebook usage. Screen protectors are good items that can be purchased to fit just about any computer and can help keep the screen display sharp for good visual usage. Another product made for portable computers is a pad that keeps computers from giving off too much heat.
Coolant fans are another option that is useful for portable computer users who want an easy attachment to their notebooks while working. Coolant fans attach to a USB port and runs with an external motor that provides cool air around the work space. For those who work outside or do extended stays in hot climates, this can be a major relief. "The Lord is good to all: and his tender mercies are over all his works." (Psalm 145:9) A laptop ac adapter is also helpful for those who travel extensively and need the ability to power their portable units no matter where they find themselves. There are many types of adapters from which to choose that may fit specific computers or may be universal units that fit just about any type of digital equipment. Many consumers prefer universal units so that they can plug in other products such as PDAs or DVD players that they may own no matter where they travel. Some are very lightweight and take very little room to pack, but provide all the wattage that is needed to power up.
These can be used in cars or when flying and make life much easier for the constant traveler. These adapters do not weight very much nor do they require much packing space. Most are not over 12 ounces or so and are easy to connect to most auto or in flight connections. There are many enhancements for portable computers that are found in a variety of prices, styles and functions. Laptop accessories such as a laptop ac adapter or a surge protector are particularly useful for those who travel extensively. Be sure to check out all warranties and guarantees before purchasing any extras for notebooks in order to receive the best service or repairs if ever required.
'Coolpads' allow the underside of a notebook to remain cool as well as the ability to swivel around for visual display if needed. Many computer users are enthusiastic about the wireless capabilities that many extras allow. Laptop accessories such as a wireless mouse and wireless keyboard are great additions for those want to expand their cable-free equipment. Hooking up a wireless mouse and wireless keyboard to a notebook can provide an almost desktop feel to portable computers. The wireless mouse is especially appealing to those who prefer its function to the typical touch pad provided on most laptops. For those who may already have a laptop ac adapter but want to be able to power up from the cigarette lighter in a car, there are auto and air adapters that can be purchased.

First Barcode Scanner

The barcode wand was the first introduced scanner. The way this unique little scanner worked is that at the end of the wand is a tiny LED light and photoreceptor. The light would shine on the barcode and reflect the image back to the receiver. The receiver would decode the information that it read in the barcode. The user would have to touch the barcode and a certain angle similar to holding a pen in order for the barcode wand to read the data. It was pretty easy to use once the user got the hang of it.

Today, you will find an array of barcode scanners with the CCD scanner being the most popular. A CCD barcode

scanner is similar in ways to the barcode wand. On the other hand, it is much more advanced with an entire row of

LED lights and receivers. When the barcode scanner reads the barcode, it receives the entire barcode instead of a

small portion at a time, thus improving its performance. There is less room for mistakes and it the CCD scanner

allows a faster read than the older wand type.

A barcode laser scanner is another type of barcode scanner that utilizes a laser diode in the scan engine. The bean

of light finds its way through various mirrors and lenses in order to make its way to the barcode. The user will

see one red line or a pattern of lines. Laser scanners will work hands free and will activate when a barcode is

presented in front of the laser while in their stand. They can also be removed and used with a trigger button to

scan the barcode.

Choosing a barcode scanner that will work for your business has quite bit to do with how you be using the scanner.

If you are a retail store and will mainly be using the scanner at a checkout counter, then a laser barcode scanner

will be the best option. However if you will be using the barcode scanner outdoors, in a factory, or in a rugged

environment, an image based scanner will be better as they are more durable. Laser types are not as durable due to

the moveable parts inside that if banged or dropped can be damaged.

If you have any doubts on the type of barcode scanner you may need for your business it would be best if you read

some reviews and talked with an expert. Do your homework, read up all the various brands, their features, options,

and warranties before you make a decision. If you do not need all the functions, then search for a barcode scanner

that only has the features you need. You can find some really great barcode scanner for under $100 and all the way

up to thousands of dollars. Why spend a thousand dollars if you really do not need the extra features?

The Method to Replace a Keyboard on a HP Pavilion ZE1000

Many people request me whether replace a keyboard is possible. Yes. it is possible to replace individual keys on your laptop's keyboard! Note that the same laptop model can have several different types of hinge mechanisms under the key. Some colors in the pictures may differ for your model. That is fine, what matters most is the shape of the hinge piece. Now, there is a guide to repairing your laptop or notebook's keyboard
Step 1: Orient the hinge
The plastic hinge mechanism must be oriented as shown for it to fit onto the metal keyboard hooks.

Step 2: Hook the hinge onto the base
Hook the inner top edge of the hinge over the top metal hook on the base of the keyboard.

Step 3: Secure the hinge into place
Snap the bottom of the hinge into place, one side at a time. This may take a bit of pressure. In this example, the bottom right side is being secured first. The bottom right and left sides of the plastic hinge should be clipped between the two metal notches protruding from the base of the keyboard on each side. You can now check that the hinge works by flexing it up and down; it should pivot easily at it's axis.

Step 4: Press the key into place
Align the key on top of its place on the keyboard, and press down evenly. All four corners of the key should click into place.
