Prospective sources include encounter data, which may or may not be contained in EHRs patient data input and randomized, prospective clinical trials. Advantages of prospective sources to inform interactive software include the ability to control and monitor the circumstances of data collection reduction (as a result of randomization) of sources of bias potential minimization of missing data potential to modify design of data collection ability to verify data accuracy and ability to validate and further test assumptions and modify existing programs. 

We have summarized briefly the key concepts and applications of a broad and complex subdiscipline of thermodynamics. Necessarily, selective judgments have been made as to what aspects of critical phase behavior are most important to chemical processing. Alternative perspectives on the role of critical phase behavior in chemical processing are readily available. For example, the role of reactive synthetic processes at critical conditions has received little attention here. As one prospective source for further links, the article by Perrut provides an especially relevant survey. Readers are encouraged to survey this literature for themselves and keep abreast of the latest developments. 

Growth faulted deltaic areas are highly prospective since they comprise of thick sections of good quality reservoir sands. Deltas usually overlay organic rich marine clays which can source the structures on maturation. Examples are the Niger, Baram or Mississippi Deltas. Clays, deposited within deltaic sequences may restrict the water expulsion during the rapid sedimentation / compaction. This can lead to the generation of overpressures. 

Prospective Processes. There has been much effort invested in examining routes to acetic acid by olefin oxidation or from ethylene, butenes, or j -butyl acetate. No product from these sources is known to have reached the world market the cost of the raw materials is generally prohibitive. 

The nature of the goods for which the mark is used or intended to be used is an essential element in determining the likelihood of confusion between otherwise similar marks. If goods bearing similar marks are of such a nature that a purchaser or prospective customer would be likely to assume that the goods have a common source of origin, then a basis for confusion exists. 

Source of Heat Industrial furnaces are either fuel-fired or electric, and the first decision that a prospective furnace user must make is between these two. Although elecdric furnaces are uniquely suited to a few apphcations in the chemical industiy (manufacture of sihcon carbide, calcium carbide, and graphite, for example), their principal use is in the metallurgical and metal-treatment industries. In most cases the choice between elecdric and fuel-fired is economic or custom-dictated, because most tasks that can be done in one can be done equally well in the other. Except for an occasional passing reference, electric furnaces will not be considered further here. The interested reader will find useful reviews of them in Kirk-Othmer Encyclopedia of Chemical Technology (4th ed., vol. 12, articles by Cotchen, Sommer, and Walton, pp. 228-265, Wiley, New York, 1994) and in Marks Standard Handbook for Mechanical Engineers (9th ed., article by Lewis, pp. 7.59-7.68, McGraw-Hill, New York, 1987). 

On a prospective basis, an agency can project its source composition and location and their emissions into the future and by the use of mathematical models and statishcal techniques determine what control steps have to be taken now to establish future air quality levels. Since the future involves a mix of existing and new sources, decisions must be made about the control levels required for both categories and whether these levels should be the same or different. 

Now it is realized that there are developing constraints on the utilizable sources of fuel and energy that feed the entire kinetic complex of human society. The prospect of the primary rate constants becoming limiting, diminishing, or even vanishing, places the associated problems high on the... 

A variety of data sources are available to inform interactive programs, including prospective data sets, retrospective databases, expert opinion, and unpub-lished/published literature. Time horizon, that is, the length of time into the future considered in the analysis over which costs and outcomes are projected, is very important here [26]. For example, if a clinical trial or the published literature only report short-term results for a chronic condition, the outcomes may come into question. This is where decision-analytic models may come... 

A number of interactive program developers advocate retrospective analyses and modeling as alternatives to prospective data sources. These sources... 

The electrocatalytic oxidation of methanol has been widely investigated for exploitation in the so-called direct methanol fuel cell (DMFC). The most likely type of DMFC to be commercialized in the near future seems to be the polymer electrolyte membrane DMFC using proton exchange membrane, a special form of low-temperature fuel cell based on PEM technology. In this cell, methanol (a liquid fuel available at low cost, easily handled, stored, and transported) is dissolved in an acid electrolyte and burned directly by air to carbon dioxide. The prominence of the DMFCs with respect to safety, simple device fabrication, and low cost has rendered them promising candidates for applications ranging from portable power sources to secondary cells for prospective electric vehicles. Notwithstanding, DMFCs were...
