BUILD A SELF-PROPELLED MAGNET 'CAR'

Steve Maxwell, an engineer at K&J magnets, created a tiny self-propelled “car” from three neodymium magnets, one AA battery, and aluminum foil. “It is a very cool scientific experiment,” he says. “You can see the interaction between electric fields and magnetic fields.”
To build Maxwell’s tiny car, place a magnet ring on a battery’s positive post and add circular magnets to both ends. Then lay down aluminum foil as a makeshift road, smoothing out any bumps. The contact between battery and foil allows an electric current to flow. Because that electricity runs per- pendicularly to the field created by the magnets, it generates torque. This rotational force rolls the car across the foil on its magnet “wheels”—quickly draining the battery in the process.

What is Line Pipe?

Definition - What does Line Pipe mean?
A Line Pipe is a high strength carbon steel pipe used for transporting crude oil, petroleum products, natural gas and water. It is a pipeline which carries only one type of fuel. These pipes are made as per metallurgical specifications developed by API (American Petroleum Institute). Line pipes are manufactured in a wide range of pipeline diameter size ranging from 2 inches to 48 inches.
Petropedia explains Line Pipe
Line Pipes are manufactured under regulations specified by API. The standard used worldwide in the manufacturing of line pipes is API Specification 5L. This specification defines that the pipeline will be used to transport crude oil, petroleum products, natural gas or water. The pipeline manufacturing industries produce two types of line pipes, i.e., seamless line pipe and welded line pipe.
Seamless line pipes are manufactured from a cylindrical bar of steel and are heated to very high temperatures. When the pipe becomes red hot, it is then pierced with a probe to create necessary holes into it. This red hot cylindrical bar is run through rollers to produce proper wall thickness and diameter.
Welded line pipe for oil and gas transportation . These pipelines are generally large diameter pipelines produced by forming steel plate into cylindrical shape and seam is closed by welding process. The quality of the welded seam is checked by using ultrasonic or radiological inspection method and pressure test is performed at each joints.
Line pipes once manufactured undergo quality and inspection checks for steel chemistry, dimensional characteristics, strength and toughness.

Cardboard display

Newspaper Rizhao June 13 hearing from 3,000 yuan / ton to 3,800 yuan / ton, although the price is still not a small gap from the last July, the highest 5400 yuan / ton, but the industry is still optimistic expectations for this: in after the paper output and prices to recover, pulp prices have been declining momentum has finally been contained, although the paper industry is now talking about "spring" if it seems too early arrival, but some data has been able to show that the Chinese paper industry We are out of the woods, slow recovery.

"Because the international pulp prices have fallen sharply, and even fell below the cost price of 3,000 dollars per tonne, from September last year after, we not only no profit at all in the production of wood pulp, or even lose money: to produce 1 ton pulp will stick into the 70-80 dollar since last month, this situation gradually began to improve: the international pulp prices began to rise gradually, to stabilize the "pulp & Paper Co., Ltd. Shandong Asia-Pacific Forest information Division Director Joe small. bridge said.

Shandong Asia-Pacific Forest Ltd addition to the production of high-grade white cardboard floor display, but also provide for other bleached kraft pulp and paper companies, their annual pulp capacity of 315,000 tons, ranking second in the domestic pulp and professional production companies. First half of 2008, affected by the international financial crisis, the price of paper and pulp prices have dropped sharply trend: in July 2008, ordinary white cardboard prices are 7,000 yuan / ton to 10 months before it fell into each four or five thousand tons; the international pulp prices is shrink nearly half, from 5400 yuan normal / ton down to 3,000 yuan crazy. This is undoubtedly Asia-Pacific Fair Pulp producers such severe test.

"Paper display and paper companies rebound in output means a huge inventory pressure gradually eased, production gradually returned to normal. Not only that, under the traditional peak season in the second quarter driven boom of paper-making enterprises upward trend is expected to continue further." Some optimism Analyzing the industry: the financial crisis caused by the downturn in the domestic paper industry has been basically in the past, the industry began to pick up. But most industry people believe, "warmer" situation needs further observation.
