Global and China Laser Equipment and Processing Industry Report, 2013-2017|
|Price: $ 2400 |
The European and American economic crisis, Asian economic slowdown and a number of other factors have impacted the development of global laser industry, and reduced the growth rate of global industrial laser sector to single digit. The growth rate of global laser system market declined from 16% in 2011 to 6% in 2012, and is expected to further drop to around 4% in 2013.
As a global processing and manufacturing center, China has continuously expanded the installation of laser processing equipment and occupied more than 10% of the global market. However, due to the weak downstream demand, the growth rate of Chinese laser equipment market in 2012 and 2013 both fell to below 10%.

Physicist suggests speed of light might be slower than thought|

Physicist James Franson of the University of Maryland has captured the attention of the physics community by posting an article to the peer-reviewed New Journal of Physics in which he claims to have found evidence that suggests the speed of light as described by the theory of general relativity, is actually slower than has been thought.
The theory of general relativity suggests that light travels at a constant speed of 299,792,458 meters per second in a vacuum. It's the c in Einstein's famous equation after all, and virtually everything measured in the cosmos is based on it in short, it's pretty important. But, what if it's wrong?
Franson's arguments are based on observations made of the supernova SN 1987A it exploded in February 1987. Measurements here on Earth picked up the arrival of both photons and neutrinos from the blast but there was a problem the arrival of the photons was later than expected, by 4.7 hours. Scientists at the time attributed it to a likelihood that the photons were actually from another source. But what if that wasn't what it was, Franson wonders, what if light slows down as it travels due to a property of photons known as vacuum polarization where a photon splits into a positron and an electron, for a very short time before recombining back into a photon. That should create a gravitational differential, he notes, between the pair of particles, which, he theorizes, would have a tiny energy impact when they recombine enough to cause a slight bit of a slowdown during travel. If such splitting and rejoining occurred many times with many photons on a journey of 168,000 light years, the distance between us and SN 1987A, it could easily add up to the 4.7 hour delay, he suggests.
If Franson's ideas turn out to be correct, virtually every measurement taken and used as a basis for cosmological theory, will be wrong. Light from the sun for example, would take longer to reach us than thought, and light coming from much more distant objects, such as from the Messier 81 galaxy, a distance of 12 million light years, would arrive noticeably later than has been calculated about two weeks later. The implications are staggering distances for celestial bodies would have to be recalculated and theories that were created to describe what has been observed would be thrown out. In some cases, astrophysicists would have to start all over from scratch.Abstract
The effects of physical interactions are usually incorporated into the quantum theory by including the corresponding terms in the Hamiltonian. Here we consider the effects of including the gravitational potential energy of massive particles in the Hamiltonian of quantum electrodynamics. This results in a predicted correction to the speed of light that is proportional to the fine structure constant. The correction to the speed of light obtained in this way depends on the gravitational potential and not the gravitational field, which is not gauge invariant and presumably nonphysical. Nevertheless, the predicted results are in reasonable agreement with experimental observations from Supernova 1987a.

Winner winner, chicken dinner!|
Roasted whole chicken is one of my favorite Sunday dinners. Add some mashed potatoes, green bean Almandine, and nothing says home cooked better. Roasting a whole chicken can be a little daunting if you’ve never done it before.
The breast can dry out, those little wing tips can burn to a crisp, the thigh might not get cooked all the way. These are easy problems to overcome. It’s all about method. Knowing some tricks can make roasted chicken easy and relatively quick.
How to brine a chicken
The first trick is brining. Brining your chicken will make juicier, help with more even cooking, and enhance flavor.
And it’s really very easy to do. All you need is a few ingredients you probably already have and a container or sealable plastic bag big enough to hold a whole chicken.
This is important because the chicken needs to be completely submerged in the brine. Here is a basic recipe for brine. The ratio for salt to water is 1 part salt to 8 parts water, so if you need to adjust that is the basis for brine.
Brine for Chicken Recipe:
Brine for Chicken
½ cup salt
2 cups water
2 cups ice water
1 lemon, quartered
3 bay leaves
3 sprigs rosemary
3 sprigs thyme
1 teaspoon black peppercorn
4 cloves garlic Place
2 cups of water (not the ice water, that’s for later), salt, bay leaves, rosemary, thyme, garlic, and peppercorns in a sauce pan. Bring to a boil.
Add lemon quarters and allow to steep for 20 to 30 minutes, then add the ice water and stir well. See how easy that was. Orange slices, juniper berries, even grapefruit can be added to give more flavor. Now, on to the chicken.
Roast Chicken Recipe:
1 whole brined chicken
¼ cup butter, cut into pats
3 cloves garlic, cut in half lengthwise
Salt and pepper
Place the whole bird in the sink. Rinse very thoroughly, being careful to remove any internal organs. Save the organs to make a stock for gravy, if desired.
Pat the chicken dry. Place the whole bird in a container large enough to submerge it in the brine, or you could use a sealable plastic bag. Add the brine. If necessary, weigh the chicken down with a plate to keep it fully submerged. Refrigerate over night.
Preheat your oven to 475. While that heats up remove the chicken from the brine and rinse well, inside and out. Pat the chicken dry and place in a roasting pan, with a rack, breast side up. This next part is important for the wing tips not burn.
Twist the wing behind the chicken’s back. It looks uncomfortable, but the bird won’t mind. At this point I like to let the bird sit at room temperature for a few minutes. I don’t know why I do this, but I was told to do so by one of the first chefs I worked for and have always done it since.
I think it helps the skin relax so that it doesn’t shrink too much butter. Rub the chicken with the garlic. Slip pats of butter and garlic cloves under the skin of the chicken. Sprinkle the bird with salt and pepper.
Place the chicken in the oven and roast for 15 minutes. Reduce the oven heat to 350 and roast for 15 minutes more. At this point I like to flip the bird over onto it’s breast to finish.
This method allows the breast to stay moist and the thighs to cook more evenly. Roast for 30 minutes more. Remove the pan from the oven, flip the bird back over onto it’s back. Place a probe thermometer into the fattest part of the thigh. You want the thermometer to read 165 degrees.
The thigh takes longest to cook, this is why we temp the chicken there, and we don’t want a lot of unnecessary holes in the breast letting juices escape. When the temperature reaches 165, allow the chicken to rest, on the rack, for 15 minutes. This let’s all the juices settle. Place on a large cutting board.
A few tips for those who are unfamiliar with carving a bird, make sure your knife is sharp, give yourself space to move around the bird. To get the most meat off the bird the first time, start slicing at the top of the breast where the breast bone peaks. Slice downward, keeping contact with the rib cage.
AND DON’T SAW, try to use smooth strokes, sawing will tear the underside of the bird up.
On the thigh I try to pull the leg away from the bird, gently, and use the knife to help release the thigh from the body. This does take practice, but I’ve taught servers how to do it tableside, so I’m sure you can do it too.
