In 1960, the first
metallic glass was developed at the California Institute of Technology. A
metallic glass is an alloy that's been heated up and then cooled down very
quickly so that it doesn't have a chance to form crystals, allowing the material
to keep its amorphous structure. Thus, metallic glass is stronger than steel or
titanium and just as tough, and 20 times stronger and stiffer than plastic.
Metallic glass is an ideal material for everything from cellphone cases to
aircraft parts.
The problem with metallic glass is that it's difficult
to mold and shape. Heat takes time to distribute through it, so the glass is
generally molded at temperatures above 1000 degrees Celsius, which is hard on
molds and is too expensive and impractical. However, now researchers have found
a cheaper way to produce metallic glass. The researchers found that if they
heated and processed the metallic glass fast enough, they could heat the
metallic glass to a liquid state that's fluid enough to be injected into a mold
and can freeze before it crystallizes.
"We've taken the economics of
plastic manufacturing and applied it to a metal with superior engineering
properties," says William Johnson, the Ruben F. and Donna Mettler Professor of
Engineering and Applied Science. "We end up with inexpensive,
high-performance,How is TMJ pain

dielectric, precision net-shape parts made in the same way plastic parts are
made—but made of a metal that's 20 times stronger and stiffer than plastic." A
net-shape part is a part that has acquired its final shape.
To heat the
material uniformly and rapidly, they shot a high-energy electric pulse into a
small rod of metal alloy,is the 'solar
panel revolution' upon us? to a temperature of 550 degrees Celsius in only
half a millisecond. Then, the softened glass was injected into a mold,Detailed
information on the causes of Hemorrhoids, the desired shape
formed and cooled in 40 milliseconds. Because the material can be heated
uniformly, only half the temperature is needed. This also means the materials
needed to form the mold can be less expensive and replaced less often.
With metallic glass being 20 times stronger than plastic and potentially
becoming just as cheap to produce, we would most likely see it replace plastic
in products to make them stronger. Like Apple is using a type of Liquid Metal in

Laurie Lieberman pops open the top of the green plastic carrying
case, which looks like something Lady Gaga would use to tote her stuff
around in. She asks for a roll of paper towels.
Let's get a
couple of things straight; this story is not about Laurie, or at least
that's what she says. It is, according to her, about Zeus,An Insulator, also called a dielectric, who has just hopped onto her fingers.
Zeus is her 4 -year-old Congo African grey parrot, who is ruffling his feathers to stretch his cooped-up, clipped wings.

Laurie usually is seen with a parrot on her shoulder.
He's
not accustomed to being carried; when he and Laurie take walks, Zeus
is generally tethered on a lead, holding onto her hand with his
reptilian talons.
"I wore grey so we would both match,How is TMJ
pain treated?" says Laurie, a honey blonde with big brown eyes for no
one but Zeus, whose grey is punctuated by a prissy petticoat of scarlet
tail feathers. (More photos.)
Zeus does talk; he has been
taught to say all kinds of things, including his name. He can bark like
a dog, meow like a cat and even mimic the blipping sound of the TiVo
remote control and the electronic hum of the treadmill when Laurie turns
it on. Sometimes, Laurie can't shut up his stream-of-consciousness
chattering and singing.
"Zeus, you can't kiss me now," she
says. "I'm wearing lipstick, and it's not good for you. And it's
probably not good for me either."
2011-05-10-Laurie50.Detailed information on the causes of Hemorrhoids,jpg
Zeus wouldn't even say "cheese" for the camera.
Perhaps
it's the strange surroundings, but he's not saying anything, not even
when Laurie prompts him. So, for now, we'll have to take her word for
everything.
Let's start with the name Zeus,is the 'solar panel revolution' upon us? which Laurie gave her feathered friend because she considers him the king of birds.is the 'solar panel revolution' upon us? But hold on! Zeus may not be a he; in fact, Laurie says she's leaning toward she.
Anyway, it's amazing how quickly Laurie fell for Zeus. When she was growing up in Fresh Meadows, she never even had a pet.
In
fact, she had a rather hard life that took her on what she calls "many
detours" that led her in a circle three times to the present.
By
15, she was out of the house and into what would become her first
residential treatment program, at Samaritan Village, where she earned
her high school equivalency degree. By her twenties, she was hanging
out all the time with her best friends -- heroin, crack and cocaine.
There will also be a small
recognition program at 5:30 p.m. to celebrate the fresh start at a new location.

(TradersHuddle.com) - Shares of Sealy Corporation (NYSE:ZZ) closed the trading
session at $2.72 near its 50 day and 200 day moving averages currently set at
$2.65 and $2.73 respectively. Sealy's price action is above the 50 day moving

Posturepedic, Stearns & Foster, and Bassett brand names.
Sealy price
action seems to be setting up for a tight range between the 50 day moving
average as support and the 200 day moving average serving as resistance.
A tiered approach to enter the stock, appears to be the best way to
maximize possible movements from the stock, as traders could enter Sealy with a
small position and wait for the stock to break out above the 200 day moving
average at $2.73, where traders could add to their position as momentum builds
with the breakout. The flip side will be if support being referenced at the 50
day moving average set at $2.65 breaks it could mean further downside in the
horizon for Sealy.
Dry cows strip grazing a
standing crop of hay are saving between 70p and 80p a cow a day, while at the
same time maintaining rumen fill.
Rather than baling long stemmy grass
for silage or hay just to feed it back later, the cows are harvesting it
themselves. And the paddock doubles up as a calving area.
Life is
simpler and cheaper, says Lydney Park Farm's herd manager Keith Davis. Time
taken to feed dry cows is an estimated 10 minutes to move the electric fence,A
glass bottle is a bottle created
from glass.Detailed information on the causes of Hemorrhoids, roll the ring
feeder over the top of a round bale and remove the wrap. "Cost savings are in
housing, bedding, feeding and labour. We could save more if we didn't feed
silage and it would be quicker. But we need to eke out the grass," he adds.The
Leading Wholesale pet supplies
Distributor to Independent Pet Retailers.
When the 480-cow herd near
Chepstow, owned by Lord Bledisloe, changed to a grazing system, the plan was to
calve the autumn block outside and keep cows grazing for as long as possible.
"What we are after is long fibre and gut fill to prevent DAs, with enough energy
to supply the dry cow's requirements," explains Mr Davis. "Grazing a standing
hay crop seemed like a good idea in that we didn't have to house cows to calve
them, then turn them out again to graze.We specialize in providing third party merchant account."
Ideally,
Mr Davis would like to rotate the calving paddocks, but logistics mean that just
5ha are close to buildings and handy for the parlour. However, he maintains that
despite calving 180 cows on the same area each year, there isn't a disease
burden. Most cows calve on the freshly-eaten new break: "They tend to eat grass
first, then the bales, then calve on the fresh stubble," he adds.
The
hay paddocks fit normally into the grazing rotation before being shut up in the
first week of June and fertilised as if for a silage crop with 45kg N/ha. No P
or K are necessary because of previous slurry applications. Grass is then
allowed to grow tall and bulky, producing seedheads. Two weeks before calving,
cows are moved in. By this stage the grass is human knee-high and green; within
two weeks, it has turned brown.
Mr Davis says it is like hay prior to
cutting. "It is not 12 ME grass and is of poorer quality. It is also a different
product at the start of grazing,is the 'solar panel revolution' upon us? compared
to the final grazing because it has been shut up for four months by then," he
says.
He moves the electric fence every 24 hours to give 4kg DM a cow a
day with a further 6kg DM a cow a day coming from big bale silage fed in ring
feeders. In addition, each cow gets an extra 1kg of a high-quality dry cow roll
along the fence line, with magnesium chloride added to water troughs. Again, in
an ideal situation, Mr Davis says cows would graze standing hay for their full
eight-week dry period. Instead, for the first six weeks they are on long stemmy
grass. This is grown off the grazing platform on SSSI land, so it hasn't had a
boost of fertiliser, but is allowed to go to seed. Strip grazing rations each
cow to 10-11kg DM a cow a day plus the dry cow roll.
X HEAD Preventing
night-time calvings
North Devon producer, Gavin Fowler is also feeding
hay as a standing crop and has found it not only keeps cows full of long fibre,
it helps prevent night-time calvings.
Over the past 15 years, he has
found that moving the electric fence at 6pm results in 90-95% of cows calving
during daylight hours. They spend their nights eating and digesting forage.
Mr Fowler has also learned that it's important to keep cows stocked
tightly on paddocks of standing hay. "It makes them eat the whole lot and not
just pick at it," he explains. "We did this to cut costs and I wanted to calve
outside without too much work. We've got six fields so we can rotate them to
reduce the disease risk and we get very healthy calves and cows. With 240 cows
calving (15 a day) in September and October, it's easier to let them do their
own work."
Paddocks are set up in June and July, fertilised to grow long
stemmy grass that reaches 18in tall and goes to seed. "Cows eat both seed and
stem and in September and October there is a bit of regrowth with clover in the
bottom."
In addition to the standing hay, Mr Fowler feeds 2kg a cow a
day of a dry cow nut plus minerals on the ground, with ad lib wheat straw in
round feeders.
OPEL Solar
International Inc. (TSX VENTURE:OPL) ("OPEL Solar,A glass bottle is a bottle created
from glass.is the 'solar panel
revolution' upon us?" or "the Company") a leading developer and supplier of
ground-based and rooftop solar tracker systems and high concentration
photovoltaic ("HCPV") solar panels announced today that Grape Solar, Inc.
("Grape") has selected OPEL Solar as its exclusive, worldwide supplier of solar
trackers for its solar projects. This is OPEL's first exclusive supply agreement
with a major photovoltaic ("PV") panel manufacturer and supplier, and it
establishes recognition that OPEL Solar's tracking systems are a preferred
industry choice. This announcement follows just days after the recent OPEL Solar
announcement of receiving the award of a turnkey solar PV installation for the
Town of Newtown Connecticut that will include OPEL Solar Trackers and Grape
Solar panels, both of which will be manufactured in the USA. The 95 kW Newtown
project will supply power to the town's waste water treatment facility.
Leon M. Pierhal, OPEL Solar CEO, indicated, "We are excited about
providing our trackers to Grape Solar and their fast growing international
operations. Grape has an impressive product line of high efficiency PV panels
from both China and U.S.The Leading Wholesale

locations, with plans for additional expansion to Ontario, Canada. We expect
that Grape's close alliances with leading solar integrators and engineering
firms will greatly enhance OPEL's sales channels and, that Grape Solar will
become a key supplier of PV Panels to OPEL's tracker customers." Pierhal
continued, "OPEL Solar's recently awarded project for the Town of Newtown and
the associated State grant money the town will receive for the project were both
award through public, competitive bid processes. The award of the both the
Project by Newtown and the state grant award to Newtown confirm that the
combination of OPEL Solar Trackers and Grape Solar panels provide a winning
combination."
Grape selected the OPEL trackers after an industry review
of the quality and value of trackers from other suppliers. Grape's CEO, Ocean
Yuan said, "OPEL Solar trackers are a great match for our Grape PV panels.
Grape's focus is making photovoltaic power more affordable and accessible. The
combination of OPEL single axis trackers with Grape's PV panels results in more
than 24% additional energy production depending on the location. This increased
energy production can be in excess of 44% when using OPEL's dual axis trackers.
Grape will be marketing the OPEL trackers to our direct customers which include
approximately 5,000 independent installers in North America. The OPEL line of
trackers is an outstanding match to our line of Grape Solar panels, including
our 280 Watt and 390 Watt panels. We expect this to be an excellent alliance for
both companies and for our customers."
While Grape has selected OPEL
Solar as their exclusive tracker supplier, OPEL Solar has chosen to refrain from
exclusive agreements with PV panels manufactures and other Solar equipment and
service provider. OPEL Solar's tracker product line can be matched with any type
of solar panel technology, providing for unlimited flexibility for integrators
and engineering firms.

Bev Rogan was watching the
coverage of Japan's earthquake and tsunami disasters in March from her Calgary
home when she saw a Red Cross appeal for blankets. That's when the idea for
Quilts for Japan came to her.Detailed information on the causes of Hemorrhoids,
"They
don't need blankets, they need quilts," said the hobby quilter. "They need
something hand-done and made from the heart."
The 55-year-old started a
Quilts for Japan Facebook group and her son designed a website to collect the
thick bedding across North America. Now Rogan has 600 quilts packed away in
boxes in a Calgary warehouse and more are on the way.
"Today I had six

Ipod nano 5th is incontrovertibly a
step up from last year's model,C." noted Rogan.
"And these are the ones
I know about."
Not an impulsive person, Rogan surprised herself by
reaching out to the devastated country. She didn't have ties to Japan before the
start of her project and has certainly stitched a new attachment to the people
picking up the pieces.
"There's no way to contemplate what they're going
through," said Rogan. "They're moving into transitional housing after being
elbowto-elbow with their loved ones and neighbours. It's going to be yet another
change for them."
Quilts have been sent to Rogan from all over Canada
and even the U.S. Many stories come along with them, like the one about the
woman who lives on a remote island in northwest B.C. Eunice Seidemann's sewing
machine is powered by solar and wind energy and she had to make a two hour boat
trip to send the quilt.
"The work in these are unbelievable -people
aren't just slapping these things together," explained Rogan. "Some of them have
been eight months to a year in the making and no quilt is made under three
weeks."
The cut-off date for accepting quilts is May 24.
The
homemade bedding will be shipped to Texas with costs paid by two Calgary
businesses: Griffin Logistics and Tundra Boiler and Instrumentation. Once the
