The Outlook

Application The transparent interface method has been tested on the SiiOyHg system and then applied to the study of SiO and SiOi molecules and their interaction with water. 

Quantitative modeling has two primary aspects. First, a quantitative model must make predictions that are qualitatively correct, meaning that 

In summary, tremendous progress has been made over the past couple of decades in the field of multiscale modeling of solid-state processes. Nevertheless, existing techniques can only handle a small fraction of the important problems that require solutions. There is plenty of opportunity at the bottom. 

Unless new and better XC functionals are introduced and DFT results are systematically improved, conventional wavefunction-based approaches should have a renaissance and remain competitive. Ultimately, when computing power evolves to the point where the cost of correlated post-HF calculations on large biomolecular systems is no longer prohibitive, DFT in its present form will have outlived its usefulness. All is not gloom and doom, however. A great deal of ongoing research is concentrated on the development new XC functionals that hopefully will push DFT beyond MP2 and other post-HF methods. The form of these XC functionals and the increased computational effort they will introduce are not yet known. 

Hopefully, the systematic improvements in XC functionals will indeed come about, and efficient codes will be developed to exploit such exciting new linear-scaling approaches for performing DFT calculations on large biomolecular systems. Ultimately, we could use these DFT methods to accurately and realistically model reactions in condensed media. DFT studies of enzymatic reaaions will undoubtedly yield valuable insights into often poorly understood mechanisms. Such applications may be overly ambitious and may not even become remotely feasible until well past the turn of the century. However, it is safe to say that at the present time, such goals are far more realistic, and hr closer, within DFT than within any wavefunction-based ab initio approach.

The front panel is the outlook for setting input values and viewing outputs, in this case E/C data. 

With the rapid development of computer power, and the continual hmovation of simulation methods, it is impossible to predict what may be achieved over the next few years, except to say that the outlook is very promising. The areas of rare events, phase equilibria, and quantum simulation continue to be active. 

There is a difference of opinion as to whether a chemical buyer or purchasing-research analyst should be product or division oriented. Those who favor product orientation cl aim they achieve a broader and deeper understanding of the outlook for the chemicals they buy and this leads to sound purchasing strategy. Proponents of the division orientation cl aim that the product-oriented analyst has too many chemicals to foUow (up to 100 specific chemicals in some companies with 10 to 15 as principal purchases). If, instead, division needs are paramount in the mind of the analyst, more profitable buys can be made. The weakness of this latter argument is that in multidivisional, multibillion doUar chemical companies, this division-oriented analyst may have as many chemicals to foUow as a product-oriented counterpart. 

Since the radioactive half-lives of the known transuranium elements and their resistance to spontaneous fission decrease with increase in atomic number, the outlook for the synthesis of further elements might appear increasingly bleak. However, theoretical calculations of nuclear stabilities, based on the concept of closed nucleon shells (p. 13) suggest the existence of an island of stability around Z= 114 and N= 184. Attention has therefore been directed towards the synthesis of element 114 (a congenor of Pb in Group 14 and adjacent superheavy elements, by bombardment of heavy nuclides with a wide range of heavy ions, but so far without success. 

Economic concerns differ sharply from those of natural scientists and engineers. The most critical difference is in the outlook towards supply development. Many economists argue that market forces allow smooth adjustments to whatever happens to the physical stock of resources. Potentially, these market forces can produce resources cheaper than other methods presently employed to cause adjustments. At worst, the cost rises will be gradual and manageable. In contrast, these economists stress the harmful effects of governments on energy. 

An important issue concerning reversible CA is their construction. In particular, we are interested in knowing if there is some systematic method by which reversible CA rules can be constructed from scratch. On the one hand - if the desire is to randomly choose a reversible rule out of the set of all possible rules, the outlook for success is very dim. Amoroso and Patt [amoro72], for example, had observed that, within the space of all possible rules, the set of nontrivial reversible rules appeared to be exceedingly small. Sears [sears71] had also shown that the set of invertible CA actually constitutes a vanishingly small subset. On the other hand, if the desire is to simply define some representative samples of reversible rules (or some set of rules that may also possess some additional special features), a number... 

Considered together these problems disable people, diminish their productivity and make their lives extremely stressful. Worse still, the outlook for improvement, given the continued rapid growth in the world population, is bleak. 

In comparison with the more standard Configuration Interaction (Cl) method, the one-particle Green s function approach offers the essential advantages, in the outlook of numerical applications on extended systems, of a stronger and systematic compactness (30) of the configuration spaces in high order approximations and of energy separability (5,31) in the dissociation limit (size-consistency). The latter is a necessary prerequisite ( ) for a correct (i.e. size-... 

This paper provides a detailed overview of the current plastics waste management situation in Japan. It discusses material, chemical, and thermal recycling, and incineration versus landfill. It also provides a flow sheet showing recycling and the treatment/disposal of plastics waste in Japan in 1991. Conclusions are drawn, and the outlook for the future is considered. 5 refs. 

As the twentieth century came to a close, the job market for computational chemists had recovered from the 1992-1994 debacle. In fact, demand for computational chemists leaped to new highs each year in the second half of the 1990s [135]. Most of the new jobs were in industry, and most of these industrial jobs were at pharmaceutical or biopharmaceutical companies. As we noted at the beginning of this chapter, in 1960 there were essentially no computational chemists in industry. But 40 years later, perhaps well over half of all computational chemists were working in pharmaceutical laboratories. The outlook for computational chemistry is therefore very much linked to the health of the pharmaceutical industry itself. Forces that adversely affect pharmaceutical companies will have a negative effect on the scientists who work there as well as at auxiliary companies such as software vendors that develop programs and databases for use in drug discovery and development. 

There is no doubt that metallic nanoparticles that have defined sizes and shapes will become key components of a number of novel, highly sophisticated products, the prototypes of which are currently emerging from the industrial R D departments. The outlook is promising for the industrial production of defined 1.4nm metal clusters for use as single electron switches or transistors, for the cost-effective fabrication of ultrapure metallic nanomaterials needed for dye solar cells or sensors, and for the reproducible production of (particularly) efficient and durable... 

Application to heterogeneous polymer solids, and elastic composites, is presented in the Section 7 (Gusev, Suter), which is followed by a summary and the outlook for the various methods reviewed here. It will be apparent to the reader that this review thus assembles several building blocks for the difficult task to bridge the gaps from the atomistic to the macroscopic scales in space and times for the simulation of polymeric materials. Integrating these building blocks into one coherent framework still is not fully solved and a matter of current research. 

The modem north American dogma of maximising production and the need to get big or get out , coupled with the fact that the largest profits in the food system are made by the processors, has made the outlook for the farmer bleak in many respects.

Effective treatment of maple syrup urine disease involves the restriction of dietary branched-chain amino acids. Long-term treatment entails the dietary restriction of the BCAAs. This is accomplished by administration of a special formula from which these amino acids are removed. The outlook for intellectual development is favorable in youngsters in whom diagnosis is made early and who do not suffer recurrent, severe episodes of metabolic decompensation [17]. 

The outlook for patients who are treated at an early age is favorable. Affected babies are normal at birth but almost all will be impaired unless they receive dietary restriction by age 3 months. Mass screening has largely eliminated the untreated PKU phenotype of eczema, poor growth, irritability, musty odor (caused by phenylacetic acid) and tendency to self-mutilation. Progressive motor dysfunction has been described in children with longterm hyperphenylalaninemia. 

AIDS is associated with aberrant lymphocyte production and it has been proposed that Li+ may have a potential role in reversing this. Additionally, 3 -azido-3"deoxythymidine (AZT, zidovudine), an effective inhibitor of viral reverse transcriptase that reduces mortality in AIDS patients, induces hematopoietic suppression in patients resulting in anemia, neutropenia, and overall bone-marrow failure [220]. In murine AIDS, the coadministration of Li+ effectively moderates this toxicity of AZT in vivo [221,222]. There are several case reports where Li+ has been administered to help reduce the hematopoietic suppression in HIV-infected patients taking AZT (for example, see ref. 223). To date, the use of Li+ has been limited to a few weeks of treatment, and varying degrees of success have been achieved nevertheless the outlook in this field is quite hopeful. 

The outlook of supramolecular chemistry is towards a general science of informed matter, bringing forward in chemistry the third component of the basic trilogy matter-energy-information. 

MTBE is made by catalytically reacting methanol and isobutylene. The outlook for MTBE is murlty because the primary application, a gasoline octane enhancer/oxygenate, is under attack because of environmental reasons. 

The outlook given in this chapter on the theory of the second-order contracted Schrodinger equation and on its methodology has been aimed mostly at convincing the reader that this theory is not difficult to understand and that its methodology is now ready to be applied. That is, in the author s opinion, this methodology can be considered as accurate and probably more economical than the best standard quantum chemical computational methods for the study of states where the occupation number of spin orbitals is close to one or zero.
