But the same technologies of oedistance learning are now finding their way onto brick-and-mortar campuses,

A mortar and pestle worked better than the desktop, and a coffee grinder worked best of all for making good bee paste.

#The Secret of the Strength of the Great wall of china Lies in Sticky Rice Mortar The use of sticky rice was one of the greatest technical innovations of the time.

Scientists have discovered the secret behind an ancient Chinese super-strong mortar made from sticky rice, the delicious oesweet rice that is a modern mainstay in Asian dishes.

They also concluded that the mortar a paste used to bind and fill gaps between bricks,

. and colleagues note that construction workers in ancient China developed sticky rice mortar about 1,

500 years ago by mixing sticky rice soup with the standard mortar ingredient. That ingredient is slaked lime,

Sticky rice mortar probably was the worlds first composite mortar, made with both organic and inorganic materials.

The mortar was stronger and more resistant to water than pure lime mortar, and what Zhang termed one of the greatest technological innovations of the time.

as the oesecret ingredient that appears to be responsible for the mortars legendary strength. oeanalytical study shows that the ancient masonry mortar is a kind of special organic-inorganic composite material,

which comes from the sticky rice soup added to the mortar. Moreover we found that amylopectin in the mortar acted as an inhibitor:

The growth of the calcium carbonate crystal was controlled, and a compact microstructure was produced, which should be the cause of the good performance of this kind of organic-organic mortar.

To determine whether sticky rice can aid in building repair, the scientists prepared lime mortars with varying amounts of sticky rice and tested their performance compared to traditional lime mortar. oethe test results of the modeling mortars shows that sticky rice-lime

mortar has more stable physical properties, has greater mechanical strength, and is more compatible, which make it a suitable restoration mortar for ancient masonry,

an artillery game, became a sensation. Can they start writing good apps? Not often, no.

So in late 2008 he wrote an artillery game that could be played on the iphone,

and tar for mortar. Then they said oecome let us build ourselves a city with a tower that reaches to the heavens

Ancient mortars and grinding tools unearthed in a large mound in the Zagros Mountains of Iran reveal that people were grinding wheat and barley about 11000 years ago.

The site contained mortars and grinding tools stone figurines and other tools suggesting a large social group lived there under fairly stable economic conditions.

its inhabitants it seems preferred to defend it with men rather than mortar. However within a few decades after a defeat against the Thebans at the Battle of leuctra the city found itself reduced to a oesecond-rate power a status from which it never recovered.

The machines can employ air cannons for launching trebuchets for flinging and a variety of torsion machines that propel pumpkins via the power of twisted cables basically anything that doesn't involved gunpowder said Grant Imahara co-host of a Science Channel special on the event which airs at 8 p m

By the 1950s biologists had developed a special type of cannon-propelled net that allowed scientists to catch groups of wild turkeys more effectively to translocate them to new areas he added.

He made beautiful landscape photographs where WORLD WAR II ordnance had exploded but have since been reclaimed by nature. And I thought that was lovely

like a mortar and pestle. The stones were coated also with several kinds of microscopic starch grains.

Europe s Ariane  5 rocket launcher, which is more expensive than competitors, was the focus of fraught discussions:

Broadly a chemical weapon is a toxic chemical delivered by an explosion such as a bomb artillery shell or missile.

Fired in liquid form contained in 15 cm howitzer shells against the Russians at Bolimov the new experiment proved unsuccessful with the tear gas liquid failing to vaporise in the freezing temperatures prevalent at Bolimov.

In consequence experiments were undertaken to deliver the gas payload in artillery shells. This provided the additional benefits of increasing the target range as well as the variety of gases released.

mustard gas (or Yperite) contained in artillery shells. Mustard gas an almost odourless chemical was distinguished by the serious blisters it caused both internally

It carried 10 to 11 men including a pilot and copilot gunners bombers a radioman and a navigator.

There weren't antiaircraft along the ridge. But existing ships that were moored still had antiaircraft.

Rice Puffs Explode From A Giant Cannon In a borrowed warehouse space in Brooklyn I witnessed last week the first test-firing of

a grain-puffing cannon. This is how puffed cereals like Kix were made originally. An iron chamber is loaded with uncooked rice

For the celebratory first blast the cannon was erected on a scaffold eight feet high with its nozzle firing down into a chamber built to collect the puffs.

and don't require the manual whack have supplanted largely the exciting cannon method. But it's alive and well at Mofad

which is currently in its fundraising stages of being brought to life some where in New york. The cannon will be on display as part of a traveling exhibit later this year.

In 2012 a 44-year-old construction worker was killed and another injured by a high-pressure stream of mortar

and doesn't have in its artillery for offense and defense--and it lets you design a strategy to control it Gabriel said.

For underwater structures lime and volcanic ash were mixed to form mortar and this mortar and volcanic tuff were packed into wooden forms.

The seawater instantly triggered a hot chemical reaction. The lime was hydrated--incorporating water molecules into its structure

Tobermorite does occur in the mortar of ancient seawater concrete however. High-pressure x-ray diffraction experiments at ALS beamline 12.2.2 measured its mechanical properties and for the first time clarified the role of aluminum in its crystal lattice.

but aren't near brick-and-mortar branches. In Africa, it's very, very important

that weakens brick and mortar. Weaker brick and mortar and weaker print means weaker publishers,

because the main thing that publishers do for authors that they can t do for themselves is put books on shelves.

They pounded off the hulls with an old mortar and pestle, winnowed the grains in an antique basket
