ABSTRACTSince epilayers of GaAs grown at low substrate temperature (LTGaAs) and annealed at 600°C were first demonstrated to be an effective buffer layer for eliminating backgating effects, the material properties and electronic characteristics of bulk LTGaAs have been actively investigated. Less attention has been paid to thin layers of LTGaAs (∼2000Å), although these have been shown to improve gate-to-drain breakdown characteristics when incorporated as the surface insulator layer in GaAs MISFET's. In bulk LTGaAs that has been annealed for 10 minutes at 600°C, the formation of arsenic precipitates with a density of 1018 cm-3 has been observed. These are considered to be at least partially responsible for the high resistivity of LTGaAs2. While the exact mechanism of precipitate formation is currently unknown, it would seem reasonable to expect the availability of the growth surface to have a significant effect on any defect redistribution during the anneal. This surface effect would become increasingly apparent as the LTGaAs layer thickness was decreased. It is desirable for MISFET applications that the LTGaAs gate insulator layer be as thin as possible, whilst maintaining high breakdown, in order to maximize device transconductance. To achieve this, it is important to understand how the observed bulk features (such as ∼60Å size arsenic precipitates) are affected in thin LTGaAs layers

Effective Buffer

High speed bulk data transfer is an important part of many data-intensive scientific applications. TCP fails for the transfer of large amounts of data over long distance across high-speed dedicated network links. Due to system hardware is incapable of saturating the bandwidths supported by the network and rise buffer overflow and packet-loss in the system. To overcome this there is a necessity to build a Performance Adaptive-UDP (PA-UDP) protocol for dynamically maximizing the implementation under different systems. A mathematical model and algorithms are used for effective buffer and CPU management. Performance Adaptive-UDP is a supreme protocol than other protocols by maintaining memory processing, packetloss processing and CPU utilization. Based on this protocol bulk data transfer is processed with high speed over the dedicated network links.

From the foregoing considerations, the energy-linked transhydrogenase reaction emerges as a powerful and flexible element in the network of redox and energy interrelationships that integrate mitochondrial and cytosolic metabolism. Its thermodynamic features make it possible for the reaction to respond readily to challenges, either on the side of NADPH utilization or on the side of energy depletion. Yet, the kinetic features are designed to prevent a wasteful input of energy when other sources of reducing equivalents to NADP are available, or to deplete the redox potential of NADPH in other than emergency conditions. By virtue of these characteristics, the energy-linked transhydrogenase can act as an effective buffer system, guarding against an excessive depletion of NADPH, preventing uncontrolled changes in key metabolites associated with NADP-dependent enzymes and calling on the supply of reducing equivalents from NAD-linked substrates only under conditions of high demand for NADPH. At the same time, it can provide an emergency protection against a depletion of energy, especially in situations of anoxia where a supply of reducing equivalents through NADP-linked substrates can be maintained. The flexibility of this design makes it possible that the functions of the energy-linked transhydrogenase vary from one tissue to another and are readily adjustable to different metabolic conditions.

On repeated occasions in the nineteenth century, Asian cholera irrupted from its traditional center in the great river basins of India and spread in pandemic waves throughout parts of Europe, North Africa, and North America. In Spain alone 600,000 deaths resulted from cholera during four great invasions (Cárdenas, 1971: 224). The United States experienced terrifying outbreaks beginning in 1832, 1849, and 1866 (Rosenberg, 1962) which also touched parts of Mexico, Central America, and the Caribbean. Initially South America escaped the onslaught. Some Brazilians speculated that the intense heat of the equator, or the vast expanse of the Atlantic ocean, somehow offered an effective buffer to the southward spread of cholera (Rego, 1872: 84). But this “sweet illusion” was shattered in 1855. Indeed the first city in Brazil struck by Asian cholera was Belém, capital of the vast northern province of Pará located astride the equator at the mouth of the Amazon river.
