Academic problems

In summary, my recommendation for future progress in the field is not to follow the deceptively simple path of rushing toward the application of large-scale CFD simulations to complex industrial reactor systems if the basic SGS models have not first been shown to be reliable on academic problems.10 Rather, I would recommend that we proceed more cautiously with adequate attention given to the development of the fundamental physical understanding required to develop reliable CFD models. While this path will obviously require... 

One of the most valuable assets of flow-through (bio)chemical sensors is their compatibility with unsegmented-flow configurations, which endows them with major advantages over probe-type sensors including higher flexibility and automatability in addition to wider applicability to real rather than academic problems — the former are rarely addressed by using sensors. 

A somewhat academic problem also seems to have found its solution in the work of Nauman (57) who showed that RTD in systems governed by the dispersion equation could be defined as in closed systems provided the time spent by the tracer outside the reactor owing to diffusion be excluded from the count. 

If the patient is a child, is the child having any school difficulties An uncorrected refractive error may contribute to academic problems. 

The question of multiple steady states is not simply an academic problem, since at certain operating conditions a small perturbation can shift the rate, output, and selectivity into a new unfavorable regime. Potential and current oscillations observed experimentally show that such regimes are within the usual operating conditions of electrocatalysts. 

Nanotubes in the laboratory often exhibit an aspect ratio of 10 000, i.e., length L approximately in microns. From the fundamental perspective, an important stimulus of this research is the realization that such a linear geometry provided by small R nanotubes yields one-dimensional (ID) phases of matter that description is certainly true from the phase transition perspective (since only one dimension approaches infinity in the thermodynamic limit). The subject of ID matter has been studied as an academic problem for many years [17, 18]. An intriguing aspect of the subject is that no phase transitions occur in a strictly ID system at finite temperature (T). In the nanotube environment, however, ID lines of adsorbed molecules can interact with neighboring lines of molecules, resulting in a 3D transition at finite T. To this date, in fact, predictions have been made of ID, 2D, 3D, and even 4D phases of matter in this novel environment [19, 20]. All such regimes will be discussed, to some extent, in this chapter and Chapter 15. The rich variety of phenomena has made theoretical study both enjoyable and rewarding.

As we shall demonstrate below, the necessity of description of phenomena of a discontinuous nature, proceeding with a continuous variation of control parameters, follows from the experimental studies. Thus, the problem of description of such processes ceases to be an academic problem. 

This might seem to be an academic problem, with little chance of practical verification. In fact, individual atoms can be trapped in a rare-gas matrix, and the size of the lattice site in which they are confined is large enough that the first Rydberg states can be observed, albeit weakly, whilst higher members are quenched. 

There are both practical and academic problems associated with setting standards for sterility on the basis of inactivation factors. 

Relatively few real problems, as opposed to academic problems, have the form Given this, calculate that, where there is a unique answer and the task is to find it. Real problems are sloppy, often poorly defined, and don t come neatly packaged with exactly the information needed to solve them, and if there is a correct or optimal answer it usually begins with It depends. Since that is the kind of problem our graduates will face throughout their careers, it makes sense to start teaching them to deal with such problems while they are still with us. Felder (1987, 1988) suggests a...

Once it has been determined that a problem really exists, the suspects should be screened. This is the generate step. A common cause of problems results from changes in process inputs. The adage garbage in, garbage out is universal and applies to chemical processes. Component flows into the process must be verified and compared to those for normal operations. If a problem appears as a result of process inputs, go to Phase 3. If a problem is known to involve a single unit (which may be true only for academic problems), consider possible unit malfunctions (some are listed under Phase 2). In this case, you should also go direedy to Phase 3. 

My relationship with Paul Bartlett began with my first visit to Harvard and the tour through his laboratories in about 1961, when I was a young faculty member. During that tour of Bartlett s labs years ago, and in subsequent years whenever any critical academic problem came up, like many other young men I sought to find the answer to the critical question, "How does PD handle that ". Paul Bartlett has stocked the universities and laboratories of America with persons that have looked to him as a teacher, a mentor, and a father figure for a period of nearly 40 years. 

In anisotropic systems there is an intrinsic mechanism which raises the orientational degeneracy by inducing preferred directions for the wavevectors characterizing the structures. e illustrate this property on the rather academic problem of the Turing instability in the Brusselator model in a 2D uniaxial medium (the... 

The influence of finite temperature on the Casimir force has been calculated [120-122] and some experiments have been carried out [123]. Consensus has, however, not been reached. This is partially due to the fact that an experimental verification is difficult since van der Waals forces at large distances are weak. For that reason, they are usually also insignificant, and our poor understanding is more an academic problem.
