  • Since the maintenance-free sealed nickel/cadmium accumulator became of high importance in the market, in the middle of the 1950s (Figure 17.1), the German battery company Sonnenschein has invented the first maintenance-free portable lead-acid batteries in small sizes in modules of 2 to 12 V between 1 and about 30 Ah. These batteries have been absolutely maintenance free and because of their immobilized electrolyte they could be used in any position without leakage.

  • Municipal waste consists of everyday items that we use and then throw away, such as product packaging, grass clippings, furniture, clothing, bottles, food scraps, newspapers, appliances, paint, and batteries, which comes from our homes, schools, hospitals, and businesses. Industrial hazardous waste is waste from industrial practices that causes a threat to human or environmental health. As waste generation increases with population expansion and industrialization, waste disposal has become a global challenge for both the developed and developing countries....

  • Oceans provide enormous and diverse space for marine life. Invertebrates are conspicuous inhabitants in certain zones such as the intertidal; many are soft- bodied, relatively immobile and lack obvious physical defenses. These animals frequently have evolved chemical defenses against predators and overgrowth by fouling organisms. Marine animals may accumulate and use a variety of toxins from prey organisms and from symbiotic microorganisms for their own purposes. Thus, toxic animals are particularly abundant in the oceans.

  • Gaseous injection of sulfur dioxide was beginning in 1993 and is a part of the quick-germ (QG) and quick-fiber (QF) techniques currently being devel- oped. There is revived interest in the use of special corn hybrids high in starch, though their use is still not widespread. Membrane filtration and yeast immobilization were being used in some plants in 1993, but their use, contrary to expectations, has not increased. Bacterial fermentation is still not used commercially, nor is cellulosic conversion of corn fiber.

  • Fluorescence ratio imaging indicates that immobilized, aspirin-treated platelets, loaded with Fura-2, respond to inositol 1,4,5-trisphosphate- (InsP3)-generating agonists such as thrombin by high-frequency, irregular rises in cytosolic [Ca 2+ ] i with spikes that vary in peak level and peak-to-peak interval. This differs from the regular [Ca 2+ ] i oscillations observed inother, larger cells.

  • In this paper the structural and dynamical characteristics in alumina- silicate Al2O3– 2SiO2 (AS2) liquid are investigated by molecular simulation method. Structural properties are clarified through the pair radial distribution function, distribution of TOn (T= Si, Al) coordination units and distribution of partial bond angle in TOn. Furthermore the change in diffusion mechanism between low and high pressure is revealed by transition of the structural units TOx → TOx±1. At the lowpressure, liquid AS2 exhibits the dynamics heterogeneity (DH).
