Green Laser Pointers From Green-LaserPointer.Com

Secretwise7582:

After a telescope, this is the best astronomy educational tool I've seen. At night this AAA battery powered [http://www.Green-LaserPointer.com green laser pointer] can seemingly touch the stars millions of miles away. Compared to a red laser pointer, the green beam remains visible and penetrates the air much farther. Because of its particular spectrum you see the beam and not just the end dot. Also, it's about 50 times brighter than an ordinary red laser pointer -- using the same safe low power. On a clear night it can easily shine a dot a mile away. With its sharp laser beam you can pinpoint the exact star you want, which greatly accelerates mapping and learning the constellations. I've been amazed at how much faster I've learned the heavens with one of these in hand.

The problem with [http://www.Green-LaserPointer.com green laser] pointers has been their stiff price. Only recently have they dropped below $80, which is still a lot for an educational tool. Manufacturing green laser engines is more art than science so their actual power output varies by final pointer. The lasers are sorted after they are made. The select ones near to the legal "pointer" limit of 5 milliWatts are labeled as such and are priced around $100 these days. The others are labeled as "less than 5mW" or "guaranteed to be up to 5 mW" and are priced as cheap as $80, but their actual power is not stated. For a star pointer all you need is one of these cheap ones. I've been using an in expensive "up to 5mW" version that works wonderfully.

Incidentally, you can purchase higher powered green lasers from Green-LaserPointer that exceed the mandated 5 mW. Their 95 mW green laser (6 mile range) goes for $499.95 and their scary/astounding 200 mW for $800. These are incredibly bright at night, but overkill for an astronomy aid.

Pleural Mesothelioma

2007-11-08T15:58:21Z

Secretwise7582:

Malignant [http://www.itxb.net/pleural-mesothelioma pleural mesothelioma] is the most common type of [http://www.itxb.net mesothelioma], making up over two-thirds of all cases. [http://www.itxb.net/pleural-mesothelioma pleural mesothelioma] affects the lining of the lung and chest cavity known as the pleura.

The pleura is made up of the parietal and visceral pleura. The parietal pleura lines the chest wall and diaphragm while the visceral pleura lines the lungs.

Asbestos fibers work their way into the smallest passageways of the lungs and then into the pleura. Once there, an unknown chemical reaction causes cancerous cell development. As the cells begin to divide abnormally, the pleural lining thickens and excess fluid may accumulate. Pleural thickening gradually contracts the breathing space, causing shortness of breath—often the first symptom for [http://www.itxb.net/pleural-mesothelioma pleural mesothelioma]. The fluid, once carefully measured to allow smooth movement between the lungs and other organs, now causes increased pressure, further hindering breathing. This excess fluid is often seen on X-rays, and is referred to as a pleural effusion.

Mischief and kids go hand in hand at times. For example, when digital watches became inexpensive enough for every school-aged child to have one, kids would use the glass faces to shine patches of light at other students, teachers and objects.

Kids will be kids of course, and young people are doing the same thing in schools across the country today using laser pointers. The difference is laser light from pointers poses a much greater risk to the eye than the relatively primitive method used by children in days past. The energy a pointer can direct into the eye is many times brighter than staring directly at the sun.

Use and Misuse of Pointers

Commercial laser pointers are most commonly designed to assist speakers when giving lectures or business presentations. A high-tech alternative to the retractable, metal pointer, the laser pointer beam will produce a small dot of light on whatever object at which it is aimed. It can draw an audience�s attention to a particular key point in a slide show.

Pointers are also used for other purposes such as the aligning of other lasers, laying pipes in construction, and as aiming devices for firearms.

Much like the digital watches about 15 years ago, laser pointers have become very affordable recently due to new developments in laser technology. They are widely available at electronic stores, novelty shops, through mail order catalogs and by numerous other sources. As inexpensive as $20 or even less, they are in the price range of other electronic toys and are being treated as such by many parents and children. One woman wrote the Laser Institute of America describing how other mothers she knew bought laser pointers for their elementary-aged children so they could imitate Luke Skywalker and Darth Vader and duel with them.

[http://www.warnlaser.com Green laser pointers] are not toys! This lesson was brought home to a small school district in Wisconsin in the fall of 1996. A 16-year-old girl was illuminated in the eye from the beams of laser pointers used as pranks. She experienced two momentary exposures, one while performing a pom pom routine and again while walking down a hallway. She reported the incidents to her parents, adding that after the first exposure, everything looked green; after the second, she could temporarily not see out of her right eye.

While this is one of the most dramatic examples to date, there are numerous reports of similar, momentary exposures across the U.S. and the U.K. While it seems clear such brief exposures can cause only brief effects, there is no reason to ever shine a pointer towards someone. The Laser Institute of America and the American Academy of Ophthalmology have also received reports of people exposed for longer amounts of time, including two verified retinal injuries caused by intentionally staring into pointers. For more information about these incidents, AAO�s web site, www.eyenet.org, should be consulted.

[http://www.warnlaser.com/ laser pointers] Tips:

Never shine a laser pointer at anyone. Laser pointers are designed to illustrate inanimate objects.

Do not allow minors to use a pointer unsupervised.
Laser pointers are not toys.

Do not point a laser pointer at mirror-like surfaces. A reflected beam can act like a direct beam on the eye.

Be aware of irresponsible uses of pointers so the psychological effect will be minimized if you are illuminated by one.

Do not purchase a laser pointer if it does not have a caution or danger sticker on it identifying its class. Report suspicious devices to the FDA.

Laser experts agree that laser pointers should not be used to pull pranks. School children are not the only ones finding mischievous uses for laser pointers. A Florida man paid the price for such a prank when he was arrested for scanning the ground near an off-duty police officer. The Laser Institute of America has also received reports of individuals shining laser pointers at athletes during sporting events and at people as they are driving.

These types of incidents have started to spur government action. In November of 1997, the U.K. banned a certain class of higher-powered pointer from sale. In December, 1997, the U.S. Food and Drug Administration issued its warning against allowing juveniles to use them (see below).

The FDA requires manufacturers to place a warning on pointers, telling users not to look into the beam. These warnings are small and easy to ignore, however, as evidenced in widespread misuse of the devices.

Secondary Effects

Safety professionals are especially concerned about secondary effects, those experienced during critical activities such as driving down a busy highway. If the driver lost control due to either a split second visual effect or a psychological effect (startle or panic), the consequences could be dire. There are reports of pilots who have had to look away or hand control of a landing airplane over to a co-pilot after similar incidents from more powerful light show lasers.

Laser experts agree that transient visual effects are possible and should be addressed. These effects are called glare, flashblindness, and afterimage. While there are slight differences in the definitions scientists use for these terms, they all refer to some vision disruption that lasts only a few seconds or minutes. The Laser Institute of America has received one report where exposure to a laser pointer startled a bus driver resulting in a traffic accident.

People often have strong psychological reactions to being illuminated with a laser beam. One researcher found that at times people receive eye injuries, not from the beam itself, but by a strong response that includes vigorously rubbing or sticking their fingers in their eye.

Laser pointers are making their way into the public consciousness. Unfortunately, in one of the last episodes of the popular TV series �Seinfeld� in May, 1998, the lovable neurotic George is pursued through the streets of New York by a laser pointer-wielding prankster.

The Laser Institute of America feels that further regulation of laser pointers should now be considered. One viable option is to further limit the power that laser pointers can emit.

Education is also key. By informing parents, teachers and society at large about the potential hazards laser pointers present, any risks posed by them can be minimized, and the devices can continue to be used properly and safely, as primarily intended.

The LIA hopes that through its efforts, and those of its members and affiliated organizations, inappropriate and irresponsible uses of laser pointers are discouraged.

Multiple diabolos

2007-09-11T17:10:12Z

Secretwise7582:

== Multiple diabolos ==

Perhaps the most active area of development for [http://www.diaboloer.com diabolo] involves tricks with more than one diabolo on a single string. When manipulating multiple diabolos "low", the diabolos orbit continuously on the string in a "shuffle". Shuffles are either synchronous (commonly referred to as "sync"), asynchronous ("async"), or only using the diaboloist's dominant hand, depending on whether the diaboloist's hands' movements occur simultaneously or not.
Juggling multiple diabolos "high" involves continuously catching and throwing a number of diabolos, with never more than one diabolo on the string at any one time. Diabolists have pushed the number of diabolos juggled at once up to 6 high (although there is some controversy as to whether this counts as the number of catches achieved is so small) and 4 low. Most diabolists, however, stick to using only two or three diabolos at once. The introduction of multiple diabolos on a single string allows for many new moves. Many are applications of one diabolo moves to multiple diabolos.

* Accelerations - The diabolos are accelerated while they wrapped and the diaboloist dominant hand is pulled up in order to gain speed. 2 other ways of accelerating diabolos are either doing Chinese acceleration or the diabolos are shuffled very fast.
* Hyperloop/Sprinkler - The diabolos orbit each other inside a closed loop of string.
* Columns/Mini-columns - Two diabolos are bounced up and down on the string.
* Siteswap - A notation borrowed from toss juggling in which the diabolos are thrown in different rhythms based on a numeric description.
* Fan - Two diabolos are spun between the arms in a way which mimics the blades of a fan.
* Sun - The diabolos are swung in a circle
* Suicide - Similar to the one diabolo suicides but some tricks are not possible
* Knots - Similar to one diabolo knots, but both diabolos are wrapped up
* Stalls - This is where one or both diabolos are still spinning but not in shuffle. This allows a diaboloist to do a trick with the other.
