Hall for Cornwall networking event | July 19 | Business Cornwall
1:47 pm, July 5, 2013
There are just a few spaces left for Hall for Cornwall (HfC) Networks Club?s summer business networking event, which will take place two weeks today.
The business networking event has already attracted a wide range of different businesses and self-employed individuals wanting to make new contacts.
Delegates will be treated to summer strawberries and cream courtesy of Cornish Food Market and Kelly?s of Cornwall respectively, as well as a glass of crisp sparkling wine from St Austell Brewery.
Those wanting to improve their public speaking skills will find Richard Hainsworth?s presentation very useful. He will give delegates a taster of the ?tricks of the trade? he has picked up during his career in theatre and television, which he believes can be valuable in adding depth and confidence to each person?s ability as a speaker.
Then it?s time to see how it?s done, with a performance from Angela Stoner, winner of HfC?s 2013 Poetry Out Loud competition, who will perform three of her poems to entertain networkers.
The event will be held on July 19 in HfC?s Assembly room, 3pm ? 5pm. The event is free to attend but booking is essential; to book or for more information email Katie Hill.

Why don't spiral galaxies run out of gas? Look to the (extended) halo.
New research suggests that galaxies hold more 'normal matter' than scientists could image. This matter in the form of gas resides in halos that turn out to be about twice as vast as previously estimated.
This undated image, made by the Hubble Space Telescope and provided by the University of Utah, shows the Andromeda galaxy, the nearest neighbor to the Milky Way. New research signals that such spiral galaxies include much more 'ordinary matter' than previously estimated, which may help explain star formation.

EnlargeSpiral galaxies like the Milky Way appear to host far more ordinary matter than previously estimated, according to a recent study. That may help explain why spiral galaxies in the nearby universe are still producing stars at respectable rates when, by all rights, star formation in these galaxies should have run out of gas billions of years ago.

This matter resides as gas in an extended halo nearly 1 million light-years across. For a galaxy such as the Milky Way, whose disk is roughly 100,000 light-years wide, the halo holds as much ordinary, or baryonic matter as the Milky Way's disk, with all of its stars, gas, and dust.
Moreover, this gas, much of which is expelled from the galaxy itself, appears to get recycled ? returning to the galaxy to serve as the raw material for new stars and planets.
The evidence for this baryonic bonanza was gathered by an international team of astrophysicists and astronomers initially interested in some basic accounting, as well as in galaxy evolution.
Over the past decade, researchers have uncovered the recipe for the universe: 70 percent dark energy, a kind of anti-gravity that is accelerating the expansion of the universe; 25 percent dark matter, which astronomers can't see but infer because of its gravitational influence on matter astronomers can see; and ordinary, or baryonic, matter, which astronomers can see directly and exerts gravitational influence as well.
Theory suggests that the proportions of dark and baryonic matter in the universe should hold for galaxies as well. But the amount of baryonic matter astronomers detect in large spirals is only about 20 percent of what theory says should be there.
"Most of the matter is still out between the galaxies," either in a region around a galaxy where its gravity still holds sway, or beyond that in deep intergalactic space, says Michael Shull, an astrophysicist at the University of Colorado at Boulder and a member of the team, which was led by colleague John Stocke, also at the University of Colorado.
The gas is so tenuous, however,. that astronomers haven't been able to capture images of it. Instead, the team used the Hubble Space Telescope's exquisitely sensitive Cosmic Origins Spectrometer to detect the gas, using bright objects called quasars as backlights.
The quasars' light passes through the gas, producing spectra that reveal the gas's abundance, composition, and its motion and velocity.
Two years ago, another research team applied this backlighting technique to galaxies known to have quasars behind them and found evidence for the halos around 42 spiral galaxies. The team estimated that the halos held substantially more gas than the galaxies themselves did.
Dr. Stocke and?colleagues took another approach. In addition to using data from 11 targeted galaxies, the team, in effect,?randomly picked quasars first, then measured the halo of any galaxy that fell in between. That gave then roughly 60 more galaxies for their sample.
The earlier team, in effect, was looking for the lost car keys at night under the streetlight, Dr. Shull quips, while "we went and looked anywhere in the parking lot."
Both groups came up with similar results, he says.
Applied to the Milky Way, the results imply that the extent of the galaxy plus its halo is about twice as large as previously estimated, Shull says.
Temperatures in the halos were on the order of 1 million degrees Celsius, or 1.8 million degrees Fahrenheit. But the halo also held so-called warm clouds, which tended to populate the inner half of the halo and consisted of elements heavier than hydrogen and helium. The team estimates that the warm clouds lacked the mass to account for more than about 10 to 15 percent of the total baryonic matter spiral galaxies should have. But when the hotter halo gas was included, the books could be brought into balance.
The circumgalactic medium also is thought to play a key role in replenishing a spiral galaxy's reserves of gas for star formation, Shull explains.
The warm clouds, relatively rich in heavier elements, likely represents gas expelled from the galaxy, where stars form the heavier elements and enormous stellar explosions called supernovae eject the enriched gas into the circumgalactic medium. Some of that expelled gas doesn't move fast enough to escape the galaxy's gravitational tug and so rains back onto the galactic disk where it can help form new stars, he says.
The warm clouds that remain, however, may provide a vital service to the galaxy ? cooling some of the hotter gas that surrounds it, Shull suggests. This cooled, denser gas has lost energy and so stands a better change of getting drawn in to the galactic disk to serve as additional star fodder.
The team's results appeared recently in the Astrophysical Journal.

US factory orders rise 2.1 percent in May
WASHINGTON (AP) ? Orders to U.S. factories rose in May, helped by a third straight month of stronger business investment. The gains suggest manufacturing may be picking up after a weak start to the year.
The Commerce Department said Tuesday that factory orders rose 2.1 percent last month. April's increase was revised higher to 1.3 percent from 1 percent.
Most of the increase in May was due to a big jump in volatile commercial aircraft demand. Still, businesses also ordered more machinery, computers and household appliances.
A category of orders that's viewed as a proxy for business investment plans ? which excludes the volatile areas of transportation and defense ? rose 1.5 percent. That was even stronger than solid gains in the previous two months.
This measure of business investment hadn't increased for three straight months since the fall of 2011. The consecutive gains suggest U.S. manufacturing could improve in the second half of the year.
Manufacturing has struggled this year after helping propel the economy in the first three years after the recession ended. U.S. factories have seen less demand for exports because of weaker global growth. And businesses reduced their investment in machinery and equipment in the first quarter.
The May report showed that orders for long-lasting goods, from power generation equipment to ships and boats, rose 3.7 percent in May. Orders for nondurable goods, including paper, chemicals and oil, rose 0.7 percent.
Demand for commercial aircraft surged nearly 51 percent, after an 18.4 percent gain in April and a drop of 43.3 percent in March.
Orders for autos and auto parts fell 2 percent, after jumping 4.1 percent in April. Still, the decline is likely temporary.
U.S. automakers on Tuesday reported healthy sales gains in June. Ford Motor Co.'s sales soared 13 percent in June compared with a year earlier. Chrysler's sales rose 8 percent. That suggests auto production will resume a healthy pace in the coming months.
The overall gain in factory orders follows another report that shows manufacturing activity picked up in June. The Institute for Supply Management's index of manufacturing activity rose to 50.9 from 49. Any reading above 50 indicates expansion.
The ISM index showed that new orders and production both jumped. But a gauge of employment fell sharply, suggesting factories cut jobs for the fourth straight month.
The U.S. economy expanded at only a 1.8 percent annual rate in the first three months of the year, the Commerce Department said last week. That was much slower than its previous estimate of a 2.4 percent rate.
The main reason for the downgrade was consumers spent less on services than initially thought. Spending on long-lasting factory goods, such as cars and appliances, was stronger.
Economists expect growth remained tepid in the April-June quarter. Most estimates range between a rate of 1.5 percent and 2 percent.
