New sessions should be routed so that the network resources are used in an efficient manner. This implies that the system needs to be capable of supporting traffic between the same two endpoints using multiple path alternatives. The QoS guarantees for existing voice connections should be unaffected when new sessions are established when full, this implies a requirement that new session requests should be rejected if insufficient network resources are available. The network should be resilient to mass calling events. This implies that call rejection should be performed at the edge of the network to avoid placing undue load onto the core network routers.

You can use the Security Configuration and Analysis snap-in at any time to analyze current system settings against a baseline template. Performing this analysis allows you to do the following:

downloads new updates, and presents a local notification message allowing a locally logged-on (or Remote Desktop) administrator to install the update.

Each of these values must be added to the registry key HKLM\SYSTEM\CurrentControlSet\ Services\AFD\Parameters. Table 19-5 lists the parameters and the recommended levels of protection.

equipment, either annually or semiannually for 10 years or more before replanting is needed and that it is able to reach deep into the soil for water and use water very efficiently. Switchgrass is a sod-forming, warm season grass, which combines good forage attributes and soil conservation benefits typical of perennial grasses (Moser and Vogel, 1995). Switchgrass was an important part of the native, highly productive North American tallgrass prairie (Weaver, 1968; Risser et al., 1981). While the original tallgrass prairies have been severely reduced by cultivation of prairie soils, remnant populations of switchgrass are still widely distributed geographically within North America. Switchgrass tolerates diverse growing conditions, ranging from arid sites in the shortgrass prairie to brackish marshes and open woods. The range of switchgrass extends from Quebec to Central America. Two major ecotypes of switchgrass occur, a thicker stemmed lowland type better adapted to warmer, moister habitats of its southern range, and a finer stemmed upland type, more typical of mid to northern areas (Vogel et al., 1985). The ecologic diversity of switchgrass can be attributed to three principal characteristics, genetic diversity associated with its open pollinated reproductive mode, a very deep, well-developed rooting system, and efficient physiologic metabolism. In the southern range, switchgrass can grow to more than 3 m in height, but what is most distinctive is the deep, vigorous root system, which may extend to depths of more than 3.5 m (Weaver, 1968). It reproduces both by seeds and vegetatively and, with its perennial life form, a stand can last indefinitely once established. Standing biomass in root systems may exceed that found aboveground (Shiflet and Darby, 1985), giving perennial grasses such as switchgrass, an advantage in water and nutrient aquisition even under stressful growing conditions. Physiologically, switchgrass, like maize, is a C4 species, fixing carbon by multiple metabolic pathways with a high water use efficiency (Moss et al., 1969; Koshi et al., 1982). In general C4 plants such as grasses will produce 30 percent more food per unit of water than C3 species such as trees and broadleaved crops and grasses and are well adapted to the more arid production areas of the mid-western United States where growth is more limited by moisture supply. Besides showing great promise as an energy crop for energy production, switchgrass also restores vital organic nutrients to farmed-out soils and with its extensive network of stems and roots (the plants extend nearly as far below ground as above), it is also a valuable soil stabilization plant.

(Enecon, 2002). Methanol was the first fuel from wood and is often called wood alcohol. Ethanol has been the focus of research at the Forest Products Laboratory. There has been little attention to diesel fuel from wood, although there has been some research on production from synthesis gas and through utilization of extractable materials from wood. The United States accounts for about 23 percent of the world s emissions of carbon dioxide. Of the United States sources of carbon dioxide, electric power accounted for 35 percent, transportation 30 percent, industry 24 percent, and residences 11 percent. Obviously, if we re to do our share in reducing carbon dioxide emissions, we should consider making a change in using more non-fossil fuels. The transportation industry is based almost totally on the use of liquid fossil fuels and measures are under consideration to reduce this consumption. Liquid fuels that could be suitable for use in transportation vehicles have been made from wood for a long time. Methanol was commonly called wood alcohol, and this term is still used. Cellulose which is the largest wood component could be dissolved in concentrated acid solutions and converted to sugar, a precursor for making ethanol. A dilute sulfuric acid hydrolysis process was used to make ethanol during World War I and wood hydrolysis received considerable attention in Europe during the period between the World Wars I and II. Wood hydrolysis plants continue to operate in Russia. However, methanol and ethanol are not the only transportation fuels that might be made from wood. A number of possibilities exist for producing alternatives. The most promising biomass fuels, and closest to being competitive in current markets without subsidy, are (a) ethanol, (b) methanol, (c) ethyl-t-butyl ether, and (d) methyl-t-butyl ether. Other candidates include isopropyl alcohol, sec-butyl alcohol, t-butyl alcohol, mixed alcohols, and t-amyl methyl ether. Ethanol or grain alcohol is not restricted to grain as a feedstock. It can be produced from other agricultural crops and ligno-cellulose compounds such as wood. It has often been advocated as a motor fuel, and has been used frequently in times of gasoline scarcity. Today Brazil is the only country that uses large quantities of ethanol as a motor fuel, but even in the United States we use close to a billion gallons per year. In Brazil, 95 percent alcohol is used as a neat fuel or anhydrous ethanol is used in admixture with gasoline. In the United States we use anhydrous ethanol in mixtures of 10 percent ethanol with 90 percent gasoline. The high cost of ethanol production in comparison to gasoline is a major disadvantage, and in the United States only subsidies for biomass ethanol make it competitive. However, because of the perceived ability of ethanol and other oxygenated fuels including alcohols and ethers to reduce air pollution in 90 percent carbon monoxide and ozone nonattainment areas in the United States, the cost disadvantage may become secondary, at least in these areas. Other reasons for considering fuels alternative to petroleum include energy security within national borders, balance of trade, and tax policies. Another possibility for oxygenated fuels is methanol. Methanol could conceivably be made from grain, but its most common source is natural gas. Use of natural gas is better for reducing carbon dioxide production in comparison to other fossil fuels, but use of renewable fuels instead of natural gas would be still better. It can be made from coal or wood with more difficulty and lower efficiency than from natural gas. Methanol has long been used as the fuel for race cars at Indianapolis and some other race tracks, not only because of its clean-burning characteristics, but also because of its efficiency, low tire hazard, and high octane rating. High octane rating is characteristic of all oxygenated fuels, including ethanol, methanol, ethyl-t-butyl ether, and methyl-t-butyl ether. A large part of the success of ethanol from grain in the current United States mix of motor fuels is due to its ability to raise octane rating in a 10 percent mixture of ethanol with 90 percent gasoline. However, it is the recent phenomenal growth in the use of methyl-t-butyl ether (MTBE) as an octane enhancer that has captured worldwide attention. Methyl-t-butyl ether is made by reacting isobutylene

Typically, a user stores XML documents in a file system so that they can be reused. Remember, XML data are independent of applications. A specific XML document may have to be saved to a file system or to a database in order to be reused in the same format. An XML document is a text file, so after it is saved in a file system, it can be manipulated by a text editor, a word processor, a spreadsheet, or a database. Storing XML documents in a file system is adequate for many purposes. However, a file system is too limited for mission critical information that will be widely shared or reused. For example, a simple file system is not adequate for very large documents, which are more easily broken into segments for simpler use. Just as with Web pages, a set of smaller pieces is much easier to navigate and manipulate than one very large document. If these segments will change frequently and independently, then separating them is superior to maintaining a single monolithic document. With different segments, each section can be worked on separately and in parallel with other sections, resulting in faster changes, and more current, up-to-date documents. In fact, each segment may be a different format, so that different tools are used for different sections. A simple example is a compound document under Microsoft Windows. If a spreadsheet and a graphic are embedded within an MS Word document, then MS Excel and MS PowerPoint are used for those sections. However, XML enables the next level of functionality. Rather than a lower level application, a higher level system might be used to manipulate the various sections. For example, an inventory system might combine data from a few different sections and then automatically make changes throughout the document as needed. Then a billing system might make different calculations and propagate them throughout the document
