The use of iron-based magnets is impractical for such low fields. The differential drop-out in the wait-list showed this was impractical. They regarded the impractical, consumptive doctor as their champion. However, there are also many cases where this is impractical, or even immoral. However, for larger collections, especially in interactive systems, this becomes impractical. Rectal splinting35 is effective, but may prove impractical in a busy treatment environment. The other impractical model was a universal tax-financed pension with a flat rate. Until now, such algorithms have been seen as impractical, since they require leading submatrices of the input matrix to be invertible (which is rarely guaranteed). However, it is impractical to construct a cohort life table by empirically following all cohort members through year after year. Such delays in the provision of information are indeed impractical.

The bad news is that exhaustive search is usually impractical. Second, storing the complete trace is impractical for any but the smallest of problems. However, in very large models, carrying out such layers of tests is generally impractical. We hope to have shown that such criticism is not impractical perfectionist carping. His students found it to be both obscure and impractical. He insisted that valuing houses separately from land was impractical and a sinister scheme to favor urban elites.

Managing and running all these tests would be impractical without automated test tools. Several multiple-route bills were introduced in the early 1850s, but were impractical. Because of the difficulty and cost of synthesis, strigol was also impractical for use in soil. While fatigue can be caused or exacerbated by alcohol use, the symptom is so common that any relationship to alcohol becomes clinically impractical to assess. Conducting such studies at individual sites would quickly become impractical in large, multinational trials. Thus, the clinical use of ethanoltreated spermatozoa in assisted reproduction would be impractical. In the 1930s, the millowners had argued that a central employment exchange would be impractical, largely because jobbers preferred to know the workers they hired. Unfortunately, this is an extremely inefficient and impractical way to collect data. On the other hand, for highly rugged, multimodal, and multidimensional landscapes, it becomes impractical to build a global model of the whole space. The value of poetic language is that it is impractical, disruptive, even obstructive ; it impedes the communicative process rather than facilitating it. Others say it would be impractical to attend (5), or that their child would prefer them not to be there (2). Second, due to the sample size, a breakdown of all the factors that may have significantly shaped family process was impractical. Unfortunately even 'backward labelling' is impractical: it takes 'exponential time'. Except in rather simple and special cases it is impractical to use any form of shock fitting to achieve sharp definition of shocks. A drug free study would be desirable, but impractical in this population. Of course this is very expensive and impractical. Such individualisation tur ns a lesson into a mixed var iety of the individualfit activities, and is sometimes descr ibed by teachers as impractical. An agency that systematically makes impractical requests or submits unreliable data clearly risks congressional retribution; a committee that appropriates imprudently invites agency deception. If n is unbounded, it might not be possible and even if it is bounded, it might be impractical. Since the denominators in these calculations are different, direct comparison of actual cases would be impractical. We will frequently invoke combinatory completeness to define complex formal expressions that it would be impractical to write out in full. Such approaches are in general counter-intuitive and impractical, and most often fail to de®ne a path from technology to prototypical problems and domains. However, the sheer number of parameters and the difficulty of defining a sensible objective function make this approach rather impractical. Given that simple random samples are impractical, there are practical ways to reduce nonrandom sampling error. Ideally dilute solutions are impractical and aggregation kinetics might be effective also at intermediate concentrations. However, this would almost always be impractical because of space considerations. Purposive sampling was employed as a list of all the patients could not be obtained and therefore random sampling, although preferential, was impractical. With data volumes growing dramatically, manual data analysis is becoming impractical. However, in many situations, lengthy training may be too time-consuming and impractical for real decision support applications. However, it is impractical (strictly, impossible) to store all the words of the language, since this constitutes an open set. However, since audio data in a live-networked performance must take place in a highly timely manner, packet re-transmission is impractical. Colonial administrators also claimed that compliance with the ban on neutral trade was both impractical and undesirable. Instead of supporting him, they continued to propose their own highly risky and impractical constitutional strategies. However, exhaustive inventories of microbial communities still remain impractical. However, the sheer number of parameters and the difficulty of defining a sensible objective function make this approach impractical. Schemes of mass colonization were impractical, and attempts to establish all-black towns were rare and discouraging. Clearly, this approach is impractical in tropical forests, where numbers of both fruiting plant species and frugivore species routinely number in the hundreds. If lumbar puncture is refused or impractical, then the patient should be considered for empirical treatment. Although a real-world validation of the model would be desirable, such a validation would be impractical or almost impossible to devise. In these cases, precise models are impractical, too expensive, or nonexistent. The volume of data acquired is so large that it is impractical to perform manual daily inspection of data from a large geographically dispersed population. However, collection of even a few repeats can be technically impractical or prohibitively expensive. However, the authority felt them to be impractical to implement because of the assumptions about resources. Such an enterprise may prove both impractical and unlikely to yield any major new theoretical insights. At the same time it is obvious that full enforcement of the law would be totally impractical. However, this approach is both impractical and expensive. However, obtaining accurate density estimates using enumerative methods are largely impractical. Further, water for irrigation is very limited thus making alternative crops like dry-season rice impractical. A key consideration is that within an ecosystem it would be impractical to manage each component to an optimum. While the identical symmetric sections of an infinite ladder would obviously be loaded with the characteristic impedance, this is an impractical arrangement. The surface curvature and the inaccessibility of the cylindrical model (in the centre of the tunnel) make this impractical. In addition, the substantial overhead needed to run a linear programming solver makes it slow and impractical. Infections were often mixed and metacercariae moved within each cyst, making the sorting of individual cysts by collar-spine count impractical.
