China looking for new microns
http://www.abc.net.au/rural/news/content/201203/s3463658.htm
Australia's major wool buyer is expanding its buying focus.
The Chinese wool demand is moving from the finer to the broader microns.
Wool broker Rowan Woods says the major Sunshine group is driving the demand for wool broader than 22 microns.
"The big movers in the micron types is everything broader than 22.
In fact one of the biggest mills in the world has increased its orders for 22 (micron) and broader by over 400 per cent.
But 15 years ago the most of what we produced was 21 and broader and that has now fallen into the smallest category."

The two body dynamics of an orbiting particle is usually governed by Newton's
laws of gravity and mechanics. Here the Kepler problem has been studied with the
addition of the Lorentz force of magnetism. For micrometeoroids and small man made
debris particles electromagnetic interactions may become important. The space
environment is filled with charged particles, electrons and ions, that may be deposited on
a 1 - 100 microns sized particle. The orbits of such charged particles have been
modeled in earth orbit, with the dipole magnetic field superposed on the gravity field.
An initial study of this problem has been conducted. Figures 1 illustrates a 600
second time frame of particles in a 300 kilometer altitude Earth orbit with a 5.7'
inclination. The solid line is the pure Kepler problem. The dashed lines are the paths
taken by various sized particles with a single positive charge of 1.6x10-'~ coulombs.
The additional energy required to deflect these particles from a Kepler orbit
comes from the deposition of charge at the initial stage in the calculation. From there
the energy of the particle is conserved since both the gravitational and magnetic forces
are conservative, i.e. $F d r = 0.
The orbit of 1 micron sized particles has been computed and the results a r e
shown in figures 2 through 5. The results of this numerical exercise in magneto-orbital
dynamics a r e rather unexpected, but appear physically correct when studied. The
particle was set in a 2000km orbit with a 5.7' inclination. Figure 2 displays how the
magnetic field torques the orbital plane. Figure 3 then shows how the orbit is flipped
over and shoved toward the north pole. This is analogous to the spin orbit interaction in
the quantum atom. He r e the magnetic moments of the Earth's magnetic field and the
orbit a r e parallel. The flip in the orbit is a result of the system's requirement to reach a
lower magnetic energy by antiorienting the magnetic moments. The energy lost by
reorienting the magnetic moment goes into gravitational potential energy by shoving the
orbit above the north pole.
Since this model is classical, and the electromagnetic radiation emitted by the
accelerating charge is negligible, events depart from the Bohr quantum analog above.
The charged particle finds itself in a magnetic bottle near the north pole, figure 4. The
spiralling charged particle is deflected upward by the converging magnetic field. The
spiral then climbs upward only to be drawn back down by gravity. The spiral bounces up
and down gradually reaching on average a lower altitude with each bounce. This
ephemeris run went for 84000 iterations, with three seconds per iteration, before the
particle crashed into the Earth. Figure 5 is a close up of the oscillating orbital spiral
shortly before it crashes into the earth.
This problem explores a hole in the current understanding of orbital mechanics of
particles. Ions and electrons in the Earth environment are treated as obeying the laws of
electromagnetism, and collectively according to plasma physics.

Micron Associates: Industrials Weigh on Dow, But IBM Helps Restrain Losses

FOX Business: The Power to Prosper
Several industrial blue chips weighed on the Dow on Monday as traders reacted to a bout of weak economic data from China and Europe, but rising shares of technology heavyweight IBM helped to keep the losses in check.
Today's Markets
The Dow Jones Industrial Average fell 14.8 points, or 0.11%, to 12963, the S&P 500 slumped 5.3 points, or 0.39%, to 1364 and the Nasdaq Composite dipped 25.7 points, or 0.86%, to 2950.
Caterpillar (CAT: 108.94, -1.28, -1.16%) was the biggest laggard of the Dow components on a point basis, pulling 18.2 points from the blue-chip index. Meanwhile, falling United Technologies (UTX: 83.99, 0.44, 0.53%) and Boeing (BA: 73.60, 0.31, 0.42%) shares cost the Dow another 15.3 points. IBM (IBM: 201.00, 0.38, 0.19%), ExxonMobil (XOM: 85.55, 1.25, 1.48%) and Verizon Communications (VZ: 39.32, 0.22, 0.56%) helped to limit the losses, adding roughly 21.7 points between the three.
Apple (AAPL: 552.00, 6.83, 1.25%), with its massive half-a-trillion dollar market capitalization, helped shove the Nasdaq Composite and closely-tracked Nasdaq 100 index of non-financial companies fairly sharply to the downside. Other big-name technology companies like Netflix (NFLX: 106.20, -2.93, -2.68%), Micron (MU: 8.08, -0.25, -3.00%) and Nvidia (NVDA: 14.58, -0.24, -1.59%) performed poorly as well. Oracle (ORCL: 29.71, -0.42, -1.39%), Seagate (STX: 27.88, -0.45, -1.59%) and Garmin (GRMN: 47.46, -0.05, -0.11%) were the only technology stocks on the Nasdaq 100 to close higher.
Looking at the broader markets, materials shares were the biggest drags. For example, Freeport-McMoRan Copper & Gold (FCX: 38.26, -0.52, -1.34%), one of the world's biggest producers of copper and gold, dropped 3.8%. Certain consumer staples, like Kraft (KFT: 38.12, 0.17, 0.45%), managed to stave off a bigger fall.
Global Economic Data Weigh
China sliced its target for 2012 economic growth from 8%, where it has stood since 2004, to 7.5% and said its top priority is increasing the pace of internal consumer demand to make the world's second biggest economy less reliant on foreign countries. Economists have long feared a so-called hard landing for China, in which expansion there will suddenly drop.
"It's a big deal to see that revised down," James Hughes, senior market analyst at Alpari said in an interview with FOX Business, adding that data from Europe also attributed to the "negative feel" among global market participants.
A report by London-based Markit showed eurozone business activity contracting faster than initially anticipated in February. The gauge hit 49.3 in February, weaker than a preliminary reading of 49.7, and 50.4 in January. Readings above 50 point to expansion, while those below signal contraction. The individual data for the members of the 17-member currency bloc also raised concerns among economists.
"The biggest disappointment in the euro area figures was not the aggregate number, but the divergence between the core and periphery economies; Germany and France continued to see moderate expansion ... while Spain and Italy remained weak," analysts at Nomura wrote in a note to clients on Monday.
The euro dipped 0.08% to $1.3188, while the U.S. dollar fell 0.04% against a basket of six world currencies.
Data from the Commerce Department showing U.S. factory orders fell 1% in January from the month prior, a slightly smaller fall than the 1.5% economists expected, did little to ease the economic malaise on the day. The report covers machinery and other big-ticket items and helps provide an idea of the investment manufacturers have been making in the first quarter, which will contribute to broader economic growth readings, such as gross domestic product.
Volatile energy markets have been a major focus on Wall Street as well. Crude oil prices lurched higher amid worries about Iran, but then fell 2.8% in the largest decline since January last week as economic fears and unexpectedly high supplies took a toll. The benchmark futures contract traded in New York gained 2 cents, or 0.02%, to $106.72 a barrel.
Wholesale New York Harbor gasoline fell 0.43% to $3.258 a gallon. A gallon of regular at the pump costs $3.767 on average nationwide, up from $3.475 last month and $3.503 last year, according to the AAA Fuel Gauge Report.
In metals, gold fell $6.10, or 0.36%, to $1,704 a troy ounce. The 10-year U.S. Treasury yield rose by six basis points to 1.990% as traders moved out of the safe-haven asset.
Foreign Markets
European blue chips fell 0.64%, the English FTSE 100 dipped 0.61% to 5875 and the German DAX slumped 0.79% to 6866.
