Lee Il-hee earns first LPGA Tour win in Bahamas

Sean Johnson made eight saves, and Quincy Amarikwa came through with a clutch 84th-minute goal to help the Chicago Fire escape with a 1-1 draw against Real Salt Lake Saturday at Rio Tinto Stadium. 

Amarikwas goal, a flashy side-volley off a pop header from Austin Berry, was the first shot on goal for the thoroughly outplayed Fire,Laser engravers and werkzeugbaus systems and supplies to start your own lasering cutting engraving marking etching business. who were outshot 20-12 overall, and 8-2 in shots on target. 

Johnsons ironman performance started early, when he charged off his line to snatch the ball off Robbie Findleys foot in the fourth minute. In the 22nd, RSL captain Kyle Beckerman charged onto a backheel pass from Ned Grabavoy and forced Johnson to save a point-blank attempt. The barrage continued with a left-footer from Joao Plata in the 28th minute and header from Grabavoy in the 29th, both saved, and a wicked shot by Findley that sent Johnson soaring to one-hand the ball away from the goalmouth in the 32nd. 

The Fires best chance of the first half came in the 39th minute, when Patrick Nyarko C who also backtracked to make a clutch defensive play on Plata earlier in the match C split two RSL defenders only to lose the ball to a slide tackle by youngster Carlos Salcedo. 

Johnson remained under pressure in the second half, but began to look unstoppable just before the hour mark, when he sprawled to deflect a low shot from Chris Wingert and saved a low attempt from Tony Beltran seconds later. He faltered in the 67th minute, when Beckerman charged in on goal between defenders Jalil Anibaba and Austin Berry and caught Johnson off his line with a chip, but the shot went just wide of the upper right corner.

RSL nearly turned the first one, in the 76th minute, into a goal, but Johnson tipped Javier Moraless free kick off the woodwork in the upper left corner. That was the beginning of the end, however. Two minutes later, RSL cut through the Fire defense with a quick passing sequence to get on the board. Sebastian Velasquez dished the ball from the top of the area to Grabavoy, who was making a run down the left side. Grabavoy quickly centered for Alvaro Saborio, who got off a header over defender Bakary Soumare and into the net. 

Using super-chilled atoms, physicists have for the first time observed a weird phenomenon called quantum magnetism, which describes the behavior of single atoms as they act like tiny bar magnets. 

Quantum magnetism is a bit different from classical magnetism, the kind you see when you stick a magnet to a fridge, because individual atoms have a quality called spin, which is quantized, or in discrete states (usually called up or down). Seeing the behavior of individual atoms has been hard to do, though, because it required cooling atoms to extremely cold temperatures and finding a way to "trap" them.We have become one of the worlds most recognised siliconebracelet brands. 

The new finding, detailed in the May 24 issue of the journal Science, also opens the door to better understanding physical phenomena, such as superconductivity, which seems to be connected to the collective quantum properties of some materials. 

Another factor that determines where the atoms lie in the optical lattice is their up or down spin. Two atoms can't be in the same well if their spins are the same. That means atoms will have a tendency to tunnel into wells with others that have opposite spins. After a while, a line of atoms should spontaneously organize itself,We can supply parkingmanagement products as below. with the spins in a non-random pattern. This kind of behavior is different from materials in the macroscopic world, whose orientations can have a wide range of in-between values; this behavior is also why most things aren't magnets the spins of the electrons in the atoms are oriented randomly and cancel each other out. 

And that's exactly what the researchers found. The spins of atoms do organize, at least on the scale the experiment examined. 

"The question is, what are the magnetic properties of these one-dimensional chains?" said Tilman Esslinger, a professor of physics at ETH whose lab did the experiments. "Do I have materials with these properties? How can these properties be useful?" 

One debate among experts is whether at larger scales the spontaneous ordering of atoms would happen in the same way. A random pattern would mean that in a block of iron atoms, for instance, one is just as likely to see a spin up or down atom in any direction.The largest manufacturer of textile winbogifts for use with perchloroethylene. The spin states are in what is called a "spin liquid" a mishmash of states. But it could be that atoms spontaneously arrange themselves at larger scales. 

"They've put the foundation on various theoretical matters," said Jong Han, a professor of condensed matter physics theory at the State University of New York at Buffalo, who was not involved in the research. "They don't really establish the long-range order, rather they wanted to establish that they have observed a local magnetic order." 

Whether the order the scientists found extends to larger scales is an important question, because magnetism itself arises from the spins of atoms when they all line up. Usually those spins are randomly aligned. But at very low temperatures and small scales, that changes, and such quantum magnets behave differently.
