Back Pay Battery Ltd core product is NiMH battery. It used to play a dominant role in three markets, namely, power tools, two-way ratios and portable power packs. However, with the Li-ion battery being introduced to the market, the market share for NiMH battery experienced a dramatic drop, and the improvement in Li-ion and other competitive technology will continue to threat and stole NiMH battery’s current core market segments. Doing business that embrace with new technology, it requires companies

bags. Some Smart shoppers choose to use paper bags instead of plastic assuming that it is an environmentally friendly and better alternative. Paper Bags are usually made up of plant fibers substance from fibrous cellulose materials as rags, woods, or barks. Paper bags were invented in the 1850’s. Paper bags are recyclable. Well known grocery stores, supermarkets, fast food chain, establishment and markets uses brown paper bags to hold their items since there are laws that are

divide these into: • Normal operational effects (regular use) • Environmental effects (internal stresses, material property degradation) • Isolated effects (lightning, impact) In a (large company) • “Design” group does general management • “Loads” group determines operating conditions • This is passed on to “stress” group that analyzes stresses and deformations • “Materials” group provides material ultimates, etc. ⇒ Need to understand each part NOTE: New approach in companies: IPT (Integrated Product

The use of Composite Materials in Aerospace, Wind Power and Automotive Technologies Introduction A composite is a multiphase heterogeneous material comprising of fibres that are embedded in a matrix [1], [2]. A composite is unlike an alloy because in an alloy, the other components have been produced by naturally occurring changes. There is a diversity of types of composites currently available, since “it is possible to design materials with property combinations that are better than those found

(1926). The “weakest link” theory applies in situations that are analogous to the failure of a chain when one of its links has failed. The Weibull distribution has been used in a wide variety of applications, including mechanical testing data from material specimens with defects. The distribution function of the Weibull distribution which models the extreme values due to the “weakest link” concept is expressed

A controversy surrounding tap water and bottled water exists. Americans spend $12 billion on bottled water every year when tap water is free. It takes 1.63 liters of tap water to make every liter of bottled water, and 1.5 million tons of plastic are used to manufacture all those bottles, noted by Biksham Gujja, head of WWF International’s Fresh Water Program (“Tap Water is Clearly Better”). Tap water is better than bottled water because it comes from the earth and is all natural, whereas bottled

Nitro-glycerine, with the molecular formula C3H5(ONO2)3, has a high nitrogen content (18.5 percent) and contains sufficient oxygen atoms to oxidize the carbon and hydrogen atoms while nitrogen is being liberated, so that it is one of the most powerful explosives used. Nitro-glycerine is extremely sensitive to shock and to rapid heating; it begins to decompose at 50 to 60 °C and explodes at 218 °C. nitro-glycerine has a high freezing point (13 °) and the solid is even more shock-sensitive than the
