How To Replace In-line Skate Bearings

If your in-line wheels seize up or spin slowly and vibrate, they might need new bearings. Rust around the outside of the wheels and/or the sound of dirt grinding inside are also signs that it is time for a change.

Instructions :

1. Use an Allen wrench to remove the axle from the front wheel.

2. Pull out the front wheel.

3. Remove the old bearings from either side of the wheel. They should pop right off if you use a bolt or something similar.

4. Place new bearings on either side of the wheel. If necessary, use a flat surface for extra leverage.

5. Place the wheel in the wheel frame.

6. Use the Allen wrench to replace the axle. If your spacer is aluminum, tighten the axle bolts as far as they will go. If your spacer is plastic, tighten the bolts as far as they will go, then loosen them slightly.

7. Spin the wheel to see how easily it rolls. If it doesn't spin freely, loosen the axle. If it wobbles, tighten the axle.

8. Repeat the steps for the remaining wheels.

Buying Guide For Skate Bearings :

Bearings made in Switzerland have the best reputation, or at least those bearings labled as "Swiss Bearings". There are many Bearing Distributors At LA who use the term "Swiss Bearings" and supply skate bearings in wholesale price. So, before placing your bearing into the cart just make sure that you have chosen the right size.

Tips & Warnings.

• Consult the manufacturer's instructions for information about your specific type of skate.
• If you skate through water or sand, you'll want to change your bearings every year. If you cover terrain that isn't as rugged, change the bearings approximately every three years.
• Select proper size and high performance skateboard bearing every time you change. For replacing your bearing I would recommend BearingsDirect . They supply high quality bearings in affordable price, where normal people can easily afford it.

New Iphone Add-On Finds Cancer

SCIENTISTS have come up with a new gadget that lets the iPhone detect CANCER.

Good call ... mobile phone gadget Handyscope can detect skin cancer

The Handyscope, which launches today, plugs into the Apple phone and converts it into a dermatoscope, which doctors use to find skin cancer.

It uses a polarising light to detect whether a mole is abnormal, before taking a picture of it and sending it off to a doctor to check.

Target ... device spots skin cancer

The image can then even be posted off to a second opinion service where world-renowned specialists can weigh in with their view.

Now experts have come out to say it could be very helpful in battling the disease.

Dr David Pye, a researcher based at Salford University, said:

"This is a powerful piece of kit which could be very useful for people in the profession assessing whether a mole is cancerous.

"Sending images around the world for expert diagnosis could be incredibly helpful and this is the first time I've ever seen anything like this before.

"During a mole examination you're looking for things like irregular edges and unusual colouration, which the device would be very good at picking up.

"However, I don't think it will be Joe Bloggs performing examinations at home - this is likely to be for doctors who could do with a second opinion."

Handyscope is made by German-based firm FotoFinder and any data is encrypted and can be password protected to keep it confidential.

At £995 for the gadget and £6.99 for the app needed to use it, the technology is not cheap.

But the firm behind it said the device had the potential to save lives.

Marketing manager Valeska Heinrich said:

"The Handyscope combines the latest communication technology with a sophisticated tool for skin cancer screening, opening up a new era for cancer diagnosis.

"This is a very exciting innovation and the first of its kind in the world. The Handyscope makes skin examinations much more convenient by allowing them to be carried out anywhere.

"The brilliant dermatoscopic photos on-screen show important details at a glance, so a decision can quickly be made on whether a mole is suspicious."

Top 10 Scariest Science Experiements Ever

While science has the power to improve our lives and cure disease, it can also be used to torture, murder, and brainwash. Here are 10 most scary experiments that destroyed lives, or have the potential to unleash doomsday.

1. Pit of Despair : Psychologist Harry Harlow induced clinical depression in monkeys by taking young macaques that had bonded with their mother, and placing them in complete isolation, in a darkened cage, for up to ten weeks. Within a few days they became psychotic, and most could not be treated.

Source : American Journal of Psychiatry

2. Russians Re-Attaching Dog Heads : This infamous propaganda film from 1940 shows Soviet Dr Sergei S. Bryukhonenko removing the head of dogs, and keeping them alive on a heart-lung machine. While possibly a Soviet fake, it produced a major stir in the west.

3. A human brain - trapped in a mouse! : Researchers at the Salk Institute in La Jolla discovered how to grow human brain cells by injecting embryonic stem cells into fetal mice. This combines the twin horrors of stem cells and transgenic research to give us either supersmart squirmy mice babies, or people with rodent brains.

Source : Washington Post

4. Stanford Prisoner Experiment : Philip Zimbardo's Stanford prisoner experiment took place in the 1970s. The psychiatrist took 24 undergraduates and assigned them roles as either prisoners or guards, in a mock prison on campus. After just a few days, 1/3 of the guards exhibited sadistic tendencies, two prisoners had to be removed early due to emotional trauma, and the whole experiment only lasted six of the planned 14 days. It showed just how easily normal individuals can become abusive, in situations where it is encouraged.

5. Implantable Identity Code : The first RFID implant in a human was in 1998, and since then it's been an easy option for people wanting to be a little bit cyborg. Now companies, prisons, and hospitals have FDA approval to implant them into individuals, in order to track where people are going. A Mexican attorney general got 18 of his staff members chipped to control who had access to documents. The prospect of a business forcing its employees to receive an implant of any type is creepy and totalitarian.

6. Stimocever : José Delgado, a Professor at Yale, invented the Stimocever, a radio implanted in the brain to control behavior. Most dramatically, he demonstrated its effectiveness by stopping a charging bull with the implant. Except this thing could control peoples actions. In one case, the implant caused erotic stimulation for a woman, who stopped looking after herself and lost some motor functions after using the stimulator. She even developed an ulcer on her finger from constantly adjusting the amplitude dial.

7. The Demon Core : During experiments with a sphere of plutonium nicknamed the "demon core" at Los Alamos laboratory, scientist Louis Slotin died when a screwdriver slipped and the sphere went supercritical. After the room grew hot and was suffused in a 'blue glow,' he saved the lives of seven other people, but died from severe radiation exposure.

8. Evolving Robots : Take a bunch of cute, round robots, give them a generation lifespan two minutes, and after a few hundred generations, they evolve to cooperate, find food, and avoid pitfalls. These robots can evolve communication and intelligence, to some degree. Incredibly short lived, with the ability to evolve greater intellect. Just wait till they break out of the lab.

9. Time Machine : Physicist Ronald Mallett's work is based on using a ring laser to create closed timelike curves, which may allow time travel. Possibly you would only be able to travel back in time to the point when the device was turned on. What could go wrong?

10. Large Hadron Collider : The Large Hadron Collider (LHC), located in an underground facility in Switzerland, is the world's largest particle accelerator, designed to ram protons or lead nuclei into each other at ludicrous speeds. The LHC has suffered a series of delays, and is meant to be back online in November 2009. Physicists admit there is an infinitesimal chance that it will generate a black hole that could destroy the Earth - or possibly another kind of anomaly that would eat the universe. Two scientists have even put forth the theory that the LHC is sabotaging itself from the future, to prevent us unearthing the elusive Higgs Boson particle; others have sued in the hope that they can shut down the LHC before it destroys the world.

Crazy Corner : Man Eating Up Light Bulbs !!

Zhang Yujian, a Chinese stuntman from Mudanjiang City, Heilonjiang Province, has eaten two light bulbs during his performance, on Monday. XInhua reports the glass-eating master has a record of three light bulbs eaten in just 120 seconds. Now, I’m not sure if he eats the entire thing, but he certainly made short work of the sharp glass, without any serious cuts.

I knew the Chinese had some pretty bizarre foods, at least for my taste, but Zhang Yujian is taking things a little too far. I wonder if he’d be interested in meeting Russia’s sand-eating woman, I bet they’d hit it off.

5 Most Interesting Tricks You Ever Thought !

Remove Scratches from CDs and DVDs : We’ve all got many precious discs that have been ruined by careless handling, regular damage while using or by the pet dog’s mauling.

Use these cool pointers to get some of them working again :

1. Clean the surface of the disc by running water (warm is better). You can even use soap or mild detergent to clean the grime. Always rub the disc from the center going out. Do not rub the disc in circular motion.

2. Let it dry in the air. This in itself may get it to work sometimes.

3. If that doesn’t work polish the CD using the inside of a banana peel, toothpaste or brasso. Again remember to gently rub from the center going outwards.

4. Once it gets going – the first thing to do is to quickly copy all data on to your PC – just in case it fails again.

How To Always Remember Names : Forgetting people’s names can prove extremely embarrassing and a complete disaster at time. Specially if it’s that pretty girl’s name you can’t recollect even though you got introduced five minutes ago (although that’s possibly because you were staring down her cleavage at that time).

The key to remembering names lies in association and repetition. Follow these two simple steps and you’ll never be in sticky situation again :

ASSOCIATION: Examine the person’s face discretely when you are introduced. Try to find an unusual feature, whether ears, forehead, eyebrows, eyes, lips or any other part (without going south again). Create an association between that characteristic, the face, and the name in your mind. The association may be to link the person with someone else you know with the same name. Alternatively it may be to associate a rhyme or image of the name with the person’s face or defining feature.

REPETITION: When you are introduced, ask for the person to repeat their name. Use the name frequently during the conversation. If it is unusual, ask how it is spelled or what it means.

Fold A Shirt In 2 Seconds : This one’s old but it never hurts to learn a technique that could potentially save you several hundred hours over a lifetime.

Keep Your Ties In Shape : Just as a smart straight tie can make an incredible impression – a worn out twisted one can ruin the situation.

Here are some simple tips to keep your ties in great shape :

Untying: This is possibly the most common mistake made. While this is the easiest way to get your tie off – never pull the thin end through the knot as this completely ruins the shape of the tie. Always remove your ties by following the tie-tying steps in reverse.

Cleaning: If you stain your tie, take action quickly. Blot the stain with cold water as this prevents it from setting. Seltzer water or club soda works best. If you get any greasy materials on your tie , water won’t do. Get some talcum powder on your tie ASAP. The powder will absorb the grease. After a few hours, brush off the remaining residue and clean with a soft cloth.

Ironing: Ironing a tie presses down on its rolled edges and ruins its shape. Avoid it as much as you can. If you need to remove wrinkles use steam. Simply hanging your tie in the bathroom while you take a hot shower will usually do the trick. For more stubborn wrinkles, consider purchasing a hand held steamer.

Storage: Spend a little on a tie-rack now, and save money in the long run by making your ties last. When traveling, fold your ties into fours and place them in your coat pocket. That will help maintain your ties’ shape.

Seal Chips Without A Clip : Few things feel as disappointingly avoidable as finding a bag of potato chips or kurkure completely crisp-less the morning after a party. This handy clip, however, shows how you can put an air-tight seal on your crunchy comestibles without having to get up for a clip.

Walking With Dinosaurs After 65 Million Years !!

The prehistoric beasts are back as Walking With Dinosaurs - The Arena Spectacular gets ready to return home in 2011.

The crowds part to reveal the mighty Tyrannosaurus Rex, six tonne killer queen of the Cretaceous period.

Created in Australia in conjunction with the BBC documentary series, Walking With Dinosaurs - The Arena Spectacular has toured internationally since 2007.

The giant Tyrannosaurus Rex indulges in a little pre-dinner conversation with Sydney school children.

After playing to packed venues across the US for the past three years, the dinosaurs are set to return to home soil in 2011 to thrill Australian audiences once more.

The baby Tyrannosaurus Rex gives some the kids a sniff before bounding off to see monster mum.

The Australian tour is set to start in April 2011and takes in Sydney, Melbourne, Brisbane, Adelaide and Newcastle.

At 12m long, the Tyrannosaurus Rex was one of the largest terrestrial carnivores of all time, tipping the scales at about six tonnes.

The animatronic creatures used in the show were created by team at the Creature Production Company and are some of the largest free-moving models in the world.

Children from Randwick Public School in Sydney get up close and personal with the mother and baby Tyrannosaurus Rex.

The show features 20 life-sized dinosaurs ranging from human height to a Brachiosaurus, standing more than 10m tall.

The dinosaurs are the brainchild of designer Sonny Tilders.

Based out of Melbourne's docklands, he and his 50-strong team, worked tirelessly for 12 months to create the beasts that appear in the show.

The stage show cost $20 million to produce.

The giant Tyrannosaurus Rex lunges towards the unsuspecting photographer.

The creatures minor movements get their own "voodoo puppeteer" who operates the mouth and eyes and deals with the sounds effects.

The kids play nice as mother watches from above.

In the three years the show has been in the US it has put on 1097 performances, playing to 4.1 million people in 144 cities.

While Sonny Tilders does an interview we take a sneak peak inside the T-Rex's driver cockpit.

The model dinosaur is powered by 18 truck batteries, weighs in at two-and-a-half tonnes and is manoeuvred around the arena by a driver located below the creature's belly.

This is the effects keyboard used during the show to create the sounds for both the mother and baby Tyrannosaurus Rex.

A total of three operators are required to work the Tyrannosaurus Rex during the show. One drives, one controls the head and tail and the other handles mouth, eyes and sound effects.

The mother and baby Tyrannosaurus Rex let out a blood-curdling roar.

The show includes ten species of dinosaurs, spanning the 200 million-year reign of these "terrible lizards".

Creature design engineer Trevor Tighe inspects the jaws of the Tyrannosaurus Rex.

The T-Rex gets its realistic look by having air-bags that inflate under the skin. Body movement is controlled by 20 hydraulic and 10 electric motors.

School children look up as the mighty Tyrannosaurus Rex moves towards them.

It takes 33 semi-trailers to move the show from town to town and it employs 65 staff when on the road.

Note : Book your tickets which is available online at DinosaurLive . So, get there with heart full of imagination with your family and walk with Dinosaurs after 65 Million Years !!!

Dragon Boy Gets Cured !

A LITTLE lad nicknamed Dragon Boy has finally been cured of a chronic skin condition which left his face covered in bumpy shell-like growths.
Muhammad Yunusov's eyes, nose and mouth and half of his scalp were previously invisible underneath the thick "horns".

For six years doctors in the former Soviet republic of Kyrgyzstan failed to find the cause of the alarming condition known as chronic granulomatous candidiasis.

'Dragon Boy'... lad was covered in horn-like growths

His parents were forced to hide him away, and placed a mask over his face, after he was taunted with names such as "dragon", "freak" and "Zorro".

Eventually, the youngster's desperate uncle took the boy to see the country's top skin specialist Professor Mir Ali Baltabaeva.

And incredibly Prof Baltabaeva took just 17 days to completely cure Muhammad.

It is understood the medic used a combination of medication and ointments to cure the condition — rather than surgery.

He said: "I learned about this unique young boy from his uncle, who came to the clinic with photographs of the child and complained that none of the doctors could diagnose him. He asked: 'Can you help my nephew?'

"The child was a terrible sight, so I ordered a separate ward for him."

Muhammad's mother burst into tears of joy when she saw he had been cured, he added.
