"Navigation" the art of good website

The evolution of computer and internet brought drastic changes in our life.Each and every company irrespective of their work nature has their own website.People who browsing the websites have a good idea about the company. While browsing through a website people should not suffer from navigation problem,then how to overcome this problem? When I searching a solution for this I found a interesting article about “how to create a simple website with proper navigation”.It’s really helpful for the firs time web creators. The article describes about navigationprinciples, general ideas to develop a new website and some tips for developers.
The extract of article says that the website created must be user friendly (i.e.)user must easily perceive and use the website, more importantly website should say “where you are” in the website. User friendly website should be created for easy search operation, because it will be helpful for user to search anything frominternet or within the website. A decent website can offer some interesting thing to visitor like an ad or offer to download/upload something etc. I learnt some useful things to develop a good website, I think it will be useful for you too.

secret of PERFUME

“Scent” the smell word is used to attract friends or people around you or even strangers!You can attract people by not only your smile or by your words, but also by scent.scent gives a pleasant feeling about you, personally I like jasmine scents, because it invokes our inner feelings! Scents have the power to cool a person. Jasmine made of white petals gives a pure look and the scent too! Scent is not only used by humans but also by animals, they use a special kind of smell naturally produced in their body for various purposes. One should use it to a allowable limit otherwise it turn you bad with a over smell.so
go and buy your favorite perfume and enjoy!!!!

Plants like woman's voice:

Plants like woman's voice? really but scientists say yes.
Plants really do like it if you talk to them. And they prefer to hear a woman’s voice. These are the conclusions of a new study by the Royal Horticultural Society into the effect of the human voice on tomato plants.Horticulturalists reached the conclusion after recordings were made of volunteers reading passages from Shakespeare’s A Midsummer Night’s Dream, John Wyndham’s The Day of the Triffids and Darwin’s On the Origin of Species.
Each plant “listened” to a different recording through the headphones of an MP3 player attached to its pot at root level. The plant that grew the most had been listening to Sarah Darwin, great-great-granddaughter of Charles, reading his revolutionary work. Her plant grew 1.6cm higher than the most successful of the two control plants.

Clean energy:

Power crisis hit the world in recent days,we have to find newer ways to produce clean energy without pollution.Brazilians produced clean energy from human wastes!!!!
Here bio-digesters — specially designed organic enzymes and bacteria — are used to break down waste water and turn it into an alternative energy sources. During three fermentation processes, the bio-digesters are unleashed on human effluent and as they break it down they produce a bio-gas, a mixture of methane and carbon dioxide, which can then be piped into homes for use in cooking.
“In fact this is a greenhouse gas, which is harmful to the atmosphere when it is unleashed, but can be collected to be useful,” said Jorge Gaiofato, technical director at the Environmental Institute, the NGO behind the scheme. Today there are more than 80 such bio-digesting ponds in Petropolis, a town some 65km from Rio de Janeiro.

Rice to prevent allergy:

In today's world people often fell to illness due to contaminated food products,one way to overcome this is to produce foods that prevent allergy,contamination etc...
scientists created a new kind of rice which saves us from allergies.A new kind of rice can fight allergies instead of causing them, Japanese researchers said. The breakthrough is a first-of-its-kind advance toward the next generation of genetically modified foods intended to improve consumers’ health, the scientists said. The new transgenic rice designed to fight a common pollen allergy appears safe in animal studies, the researchers said.
Fumio Takaiwa and colleagues note that the first generation of genetically-modified crops was designed to help keep crops free of weeds and bugs. The next generation of transgenic crops is being developed to directly benefit human health. This includes vegetables and grains that produce higher levels of nutrients, or even medicines and vaccines.Let us wait for sometime till scientists produce all kind of crops to prevent allergies.

Wash clothes with just a cup of water

Water conservation is hot topic in today's world due to scarcity of water, so we have to develop some new technology to conserve water and here is the one!!!!
Developed at the University of Leeds, the technology aims save up to 90% of water used by conventional machines, use 30% less energy.The washing machine works by replacing most of the water with thousands of tiny, reusable nylon polymer beads, which attract and absorb dirt under humid conditions.Only a small amount of water and detergent is needed to dampen the clothes, loosen stains and create the water vapour that allows the beads to work.
And after the cycle is finished, the beads fall through a mesh in the machine’s drum, and can be re-used up to a hundred times. The company behind the technology, Xeros, is initially aiming at the commercial washing market, including hotels and dry cleaners.Stephen Burkinshaw from Leeds developed the technology over the past 30 years. He said: “We’ve shown that it can remove all sorts of everyday stains including coffee and lipstick while using a tiny fraction of the water used by conventional machines.”About 20kg of the beads are added, along with a cup of water and detergent. The chips can be used up to 100 times, the equivalent of six months’ washing.

Spot the ISS:

Can you see the international space station? or can you track its movements? ow it's possible with help of Twitter and internet.
Two journalists have built an online service that would let twitter users around the world to spot the International Space Station (ISS) without a telescope.The online service, built by Dutch science reporter Govert Schilling and journalist Jaap Meijers, would let people know when they have to look up to see the ISS pass. People using Twitter can now receive an alert when the ISS will be passing at the location in their Twitter profile. All they have to do is follow the Twitter account @twisst. The space station is visible only for a few minutes on every pass and at different times, which makes it important to know when and where exactly it will be visible. That information could already be found on several websites and specialized email or phone services, but a global service that alerts ordinary people to the ISS passes at their location did not yet exist.

Robo surgeon:

In a very short span of time one could be operated by a robot instead of a doctor!!!!
Duke University researchers have built a robot that successfully found and guided a needle to a sliver of steel shrapnel, completely without human help. The technology could reduce the cost and time necessary to complete a biopsy and other surgical operations.“Eventually you could have a $10 biopsy done inside a supermarket,” said Steve Smith, a doctor at Duke University and co-author of the study.Over the last two years, the team at Duke, including recent graduate A J Rogers, successfully performed two other tasks.
The first was locating a needle with 3-D ultrasound, and then touching that needle with another needle. The second successful task for the robot surgeon was to locate, and then biopsy, a tumor inside a turkey breast, Discovery News reported.
About six months ago, the scientists upgraded their robot. The new robot, with six articulating joints and about the size of a suitcase, was tasked with finding a piece of steel shrapnel two millimeters by less than one millimeter submerged inside a water bath.
The new robot made it easier to find the shrapnel. The size of the shrapnel made it more difficult than the first two tasks; it was so small that it didn’t appear on the ultrasound. To make it larger, the Duke scientists used a high-powered magnetic field to vibrate the sliver.
All that was left was for the needle to reach out and touch the tiny metal piece. “We keep giving the robot more and more complex tasks,” said Smith. “So far the robot has accomplished these tasks automatically.”

Get a house out of a printer :

Want to see your home before start building it? here's the answer from scientists,
Your next house could come straight out of a printer, with the world’s largest 3-D mega printer almost ready to build a 10-meter-tall structure.3-D printing may soon expand beyond the small scale, reports Popsci. In 2010, the world’s largest 3-D printer will build the Radiolaria Pavilion, a 10-meter-tall structure in Pontedera, Italy.
Made out of sandstone, the building will be printed one 5-10mm layered sheet at a time.The thin layers of the structure are held together by an inorganic binder, not the normal steel reinforcements that most buildings have.The structure was designed using CAD/CAM software and then exported directly to the printer. Once printed, it only takes about 24 hours for the material to fully set. The process is also pretty environmentally sound, and if any of the building material remains unused, it can be recycled.Without the need for rigid steel reinforcement, it could also usher in an era of more free-flowing and organic architectural design.
A CAD model is fed to the CAM computer which controls a massive scanning rig, this sprays binder onto successive layers of sand, 5mm to 10mm at a time, building a detailed pattern that corresponds to the contours of the building.
Any excess sand acts to support the shapes while they’re being fabricated and can be reused for other models. The resulting artificial stone has some same characteristics as Portland cement, an in some cases exceeds it. This means that Andrea Morgante, who designed the Radiolaria pavilion, could fashion it without needing any iron reinforcements in the structure, and adopt unusual shape that would otherwise be impossible.

Bringing stars to Earth for energy :

I thought that after we utilize all our power resources, what will happen?
are we in dark? i can't imagine a life like that! as a result our scientists found
a new way to power! read below for details,

“Bringing Star Power to Earth” reads a giant banner that was unfurled across a building the size of a football stadium. The $3.5 billion site is known as the National Ignition Facility, or NIF. For more than half a century, physicists have dreamed of creating tiny stars that would inaugurate an era of bold science and cheap energy, and NIF is meant to kindle that blaze.
In theory, the facility’s 192 lasers — made of nearly 60 miles of mirrors and fiber optics, crystals and light amplifiers — will fire as one to pulverize a fleck of hydrogen fuel smaller than a match head. Compressed and heated to temperatures hotter than those of the core of a star, the hydrogen atoms will fuse into helium, releasing bursts of thermonuclear energy.
In February, NIF fired its 192 beams into its target chamber for the first time, and it now has the world’s most powerful laser, as well as the largest optical instrument ever built. But raising its energies still further to the point of ignition could take a year or more of experimentation and might, officials concede, prove daunting and perhaps impossible. For that reason, skeptics dismiss NIF as a colossal delusion that is squandering precious resources at a time of economic hardship. Just operating it, officials grant, will cost $140 million a year. Some doubters ridicule it as the National Almost Ignition Facility, or NAIF.
Moses, while offering no guarantees, argued that any great endeavor involved risks and that the gamble was worth it because of the potential rewards. He said that NIF, if successful, would help keep the nation’s nuclear arms reliable without underground testing, would reveal the hidden life of stars and would prepare the way for radically new kinds of power plants.
I think you understand the theory about new power, catch you later friends.
