Knee/膝盖

The sound of a cracking knee isn't particularly pleasant. But it gets worse when you listen up close. Knee-cracking recording "It does for most people. But for me, it actually just makes me excited." Omer Inan, an electrical engineer at Georgia Tech. "I actually feel like there's some real information in them that can be exploited for the purposes of helping people with rehab." Inan's experience with cracking knees goes back to his days as an undergrad at Stanford, where he threw discus. "If I had a really hard workout, then the next day, of course, I'd be sore, but I'd also sometimes feel this catching or popping or creaking every now and then in my knee." A few years later, he found himself building tiny microphones at a high-end audio company. So when he got to Georgia Tech and heard the Defense Advanced Research Projects Agency, DARPA, wanted better tech for knee injuries, he thought: knee-cracking recording Why not strap tiny microphones to people's knees, to eavesdrop as their legs bend? "What we think it is, is the cartilage and bone rubbing against each other, the surfaces inside the knee rubbing against each other, during those movements." He and a team of physiologists and engineers built a prototype with stretchy athletic tape and a few tiny mics and skin sensors. And preliminary tests on athletes suggest the squishy sounds the device picks up are more erratic, and more irregular, in an injured knee than in a healthy one. Which Inan says might allow patients and doctors to track healing after surgery. Details appear in the IEEE Transactions on Biomedical Engineering. "The primary application we're targeting at first is to give people a decision aid during rehabilitation, following an acute knee injury, to help them understand when they can perform particular activities, and when they can move to different intensities of particular activities." A useful thing to take a crack at.

Sojourner

-Ever since the completion of the Great Western Railway, in the 1840s, intrigue has swirled around the Box Tunnel, a long, steep bypass near Bath, England.

-The question was this: did the railway’s creator, Isambard Kingdom Brunel, really have the tunnel carved in such a way that when the sun rose on his birthday—April 9th—it would be flooded with light?

-This past Sunday, April 9th, the railway’s current engineers decided to test the rumor once and for all. They weren’t disappointed.

-“When you look from the east portal, the cutting provides a lovely V-shape,” communications manager Paul Gentleman told the Guardian.

-While the west side’s view wasn’t quite so impressive, the engineers generously chalked that up to centuries of dirt and grime.

People move to a new region for many different reasons. The motivation for moving can come from a combination of what researchers sometimes call 'push and pull factors' - those that encourage people to leave a region, and those that attract people to a region. Some of the factors that motivate people to move include seeking a better climate, finding more affordable housing, looking for work or retiring from work, leaving the congestion of city living, wanting a more pleasant environment, and wanting to be near to family and friends. In reality many complex factors and personal reasons may interact to motivate a person or family to move.

1. SLP Police Officer

Armed police have been introduced to schools across the state of NSW for reducing crime rates and educating students, and they conduct crime prevention workshops rather than patrol, buildup positive relationships with parents and students despite the relations were already under strain, and gain positive feedback from parents' groups, admitting it is innovative with some positive benefits.

Malaysia is one of the most pleasant, hassle-free countries to visit in Southeast Asia. Aside from its gleaming 21stcentury glass towers, it boasts some of the most superb beaches, mountains and national parks in the region. Malaysiais also launching its biggest-ever tourism campaign in effort to lure 20 million visitors here this year. Any tourist itinerary would have to begin in the capital, Kuala Lumpur, where you will find the Petronas Twin Towers, which once comprised the world’s tallest buildings and now hold the title of second-tallest. Both the 88-story towers soar 1,480 feet high and are connected by a sky-bridge on the 41st floor. The limestone temple Batu Caves, located 9 miles north of the city, have a 328-foot-high ceiling and feature ornate Hindu shrines, including a141-foot-tall gold-painted statue of a Hindu deity. To reach the caves, visitors have to climb a steep flight of 272 steps. In Sabah state on Borneo Island not to be confused with Indonesians Borneo you'll find the small mushroom-shaped Sipadan Island, off the coast of Sabah, rated as one of the top five diving sites in the world.

You can also climb Mount Kinabalu, the tallest peak in Southeast Asia, visit the Sepilok Orang Utan Sanctuary, go white-water rafting and catch a glimpse of the bizarre Proboscis monkey, a primate found only in Borneo with a huge pendulous nose, a characteristic potbelly and strange honking sounds. While you're in Malaysia, consider a trip to Malacca. In its heyday, this southern state was a powerful Malay sultanate and a booming trading port in the region. Facing the Straits of Malacca, this historical state is now a place of intriguing Chinese streets, antique shops, old temples and reminders of European colonial powers. Another interesting destination is Penang, known as the Pearl of the Orient. This island off the northwest coast of Malaysia boasts of a rich Chinese cultural heritage, good food and beautiful beaches.

Sea creatures are inspiring the latest devices that harness wave power. This one called the Oyster sits on the ocean floor and opens and closes as waves pass over it. Cables attach it to generators on the shore. Since November 2009, it's been powering 9,000 homes in the Orkney Islands another device looks like a snake. The anaconda is made from a rubber tube filled with water that floats just below the surface. When a swell hits the front of it, the tube is squeezed a bulge ripples down its length and powers a turbine in its tail. Prototypes are currently being tested, but the full-scale version will be 200 meters long. This system also looks like a snake but this one is made of steel. it floats near the surface where waves make its joints move. This drives hydraulic systems that power electrical generators Like the an aconda, it's still being teste. Results will prove if these devices are up to the job of supplying viable sources of green energy.

2.     Talent Shortage

The lecture was about the main reasons of talent shortage. The speaker explained about an increase in retirement of baby-boomers, which has led to a significant decrease in the number of skilled people. In addition, the collapse of loyalty has deteriorated the situation because people would change their job because of higher income. In the end, there was a conflict between what education produces and what business needs.

Shy fish

When you think of a leader, you may think of an individual who is above all bold. But a new study of fish called sticklebacks shows that shy individuals actually prefer to follow fish that are similarly timid. Researchers had trios of sticklebacks with known personalities play follow the leader. The fish were placed in a tank that had some plastic plants at one end and some food hidden at the other. In some of the groups, a bold fish and a shy fish acted as leaders, while another shy fish followed. And in other groups, it was a bold fish that did the following. The researchers recorded whether the follower sallied forth more frequently with the fish that was behaviorally similar or the one that was different. What they found is that shy fish were more likely to emerge from undercover when an equally wary fellow was already out there. Bold follower fish did not seem to care which leader they followed. Of course, no matter which fish a stickleback chose to stick with, the bold fish did lead more expeditions over the course of the experiment than their more retiring friends. That’s because the bold fish initiated more trips, regardless of who might be tailing them. The findings are in the journal Biology Letters. The researchers write that “when offered a choice of leaders, sticklebacks prefer to follow individuals whose personality matches their own, but bolder individuals may, nevertheless, be able to impose their leadership, even among shy followers, simply through greater effort.” We may soon see if such tendencies also hold true in humans, when Americans decide who they’ll follow in November. Unless, of course, something fishy happens.

Arcelor

It was taken over by Mittal, a Dutch-registered company run from London by its biggest single shareholder, Lakshmi Mittal, an Indian who started his first business inIndonesia.

The takeover battle raged for six months before Arcelor's bosses finally listened to shareholders who wanted the board to accept Mittal's third offer. The story tells us two things about European business, both positive.

First, shareholder activism is increasing in a continent where until recently it was depressingly rare.

Second, and more important, the Arcelor Mittal deal demonstrates Europe's deepening integration into the global economy.

By 2025, government experts say, America's skies will swarm with three times as many planes, and not just the kind of traffic flying today. There will be thousands of tiny jets, seating six or fewer, at airliner altitudes, competing for space with remotely operated drones that need help avoiding midair collisions and with commercially operated rockets carrying satellites and tourists into space.

Overqualified worker

Although prejudice against too-good employees is pervasive and companies tend to prefer an application who is perfect-fit because studies have consistently shown that employees who consider themselves overqualified exhibit higher levels of discontent, a surplus of overqualified candidates was a global problem, but new research shows that overqualified workers tend to perform better than other employees and they don’t quit any sooner, and empowerment can mitigate any dissatisfaction they may feel.

Drinking safe water

Today I want to talk about water and the law that surrounds drinking water, to talk about its quality, talk about what your rights are to clean water, to also give you a sense of what key threats are to drinking water, what your exposure might be, and what we might to do about it, both legally but also personally.

Water is acritical component of our environment and our bodies. Your body is close to 70percent water. You can go for several weeks, two or three on average, without food. You can only go for about four minutes without air. And you can go for maybe four or five days without water before you die. So water is absolutely critical.

And one of the key arguments I want to make today is that it’s a largely neglected area of environmental law, given the rapid increase in our knowledge about chemical threats to water quality and where those threats come from.
