Sufficiency, definition

Under the heading Alkaloids of Undetermined Constitution, have been included bases about which a good deal of information is available, though they cannot yet be allocated to sturctural groups, either because sufficient, definite information is not available, or because such data are available only about one or two members of an extensive series found in one plant or one genus. The Diehroa bases are probably quinazolines. Of the Erythrophloeum alkaloids some might be placed in the group of... 

The requirements within the product specification need to be expressed in terms that can be verified. Hence you should avoid subjective terms such as good quality components , high reliability , commercial standard parts , etc. as these requirements are not sufficiently definitive to be verified in a consistent manner. (See the later section on Design acceptance criteria and Part 2 Chapter 2 on Clarifying standards of acceptabili-fy-)... 

Hierarchical Techniques. Classes are subclassified into groups, with the process being repeated at several levels to produce a tree which gives sufficient definition to groups. 

Creating something approximating a controlled study out of a natural exposure situation is, it must be added, fraught with hazards, many of which simply cannot be overcome. It is rare that any single epidemiology study provides sufficiently definitive information... 

Therefore, we believe that this alone is not a sufficient definition for atypicality. We prefer to define atypical antipsychotics as those that are less prone to causing EPS because they work differently than the typical antipsychotics. This, of course, raises the question of just how these medications work. Using clozapine as the starting point to answer this question has proved difficult. Why The problem is that clozapine interacts with so many different types of nerve cell receptors that it becomes hard to tell which of these actions makes the difference. 

It should be remembered that few in Porta s time were free from credulity toward many marvels and superstitions which were inherited from the past and Porta s work shows that he was no exception, as much of the marvellous is found in his writings. On the whole, however, his information is definite and practical and his work is as good as could be expected of one not himself a practical experimenter or investigator, but a conscientious and scholarly student of the literature, ancient and contemporary. His directions and recipes on a great variety of applications of chemistry are sufficiently definite and detailed to be of service in stimulating experimentation and all in all, the work must have been of considerable influence in disseminating interesting and useful chemical information. 

Development, on the basis of the names of the larger parent compounds and the nor- structures and with the aid of established nomenclature rules, of logical series of simple names which are sufficiently definitive to show immediately the relations among compounds of a single... 

The subject of molecular beam kinetics is very extensive and in this section, therefore, we will deal only briefly with the relevant aspects of the topic. Molecular beam sources are often thermal, operating as a flow system with a gas or a vapour from a heated oven. The velocity distribution of species in such beams is Maxwell—Boltzmann in form. For many experiments, this does not provide sufficient definition of initial translational energy and some form of velocity selection may be used [30], usually at the expense of beam intensity. 

I suggest that these three properties - mutability, self-duplication and heterocatalysis - comprise a necessary and sufficient definition of living matter. 

Patent law is wholly a creature of statutes. Disputed cases in this field can be decided only in concord with what a statute says. It is only rarely a statute is sufficiently definite or applicable to determine by its precise terms a right result in any particular case. The judicial process of interpreting statutes is a matter of comparing the facts in a case in dispute with the facts in previously decided cases and then making a decision as to which of the usual two lines of precedents appears applicable. 

The corrected pH-ncutralization curves obtained in this manner are shown by the dotted lines in Fig. 108 the inflexions at the equivalence points are now seen to be sufficiently definite for an accurate estimate of the end-point to be possible. This method has been used for the poten-tiometric titration of amino-acids. ... 

An attractive alternative in which spectrometer line-listing routines are u.sed is as follows. After the spectral data have been Fourier transformed and saved, the proton FID is zero filled three to four times. If np = 32K, then Fn should be set to 256 or 512K. The resulting spectral lines should then have sufficient definition for peak picking. This expectation can easily be tested by examining a known multiplet, such as a triplet or quartet. The two- or three-line spacings are, of course, identical, and their equivalence must be reflected in the line listings displayed on the monitor. No matter what technique is used, J values between spin-coupled nuclei should always be reported as identical. 

The influence of SOj on SCR of NO by hydrocarbons may be reversible [20, 21] or irreversible [22, 23]. Activities and selectivities of the main and/or the deactivation reactions might be negatively affected. However, most of the studies thus far were not sufficiently definitive to reveal the cause/effect relationships for SCR catalyst deactivation by SOj. In the present study, sulfur tolerances of Cu- and H- exchanged mordenite catalysts for NO removal reaction were examined to elucidate the cause of the loss of NO removal activity of the catalysts. Deactivation by SOj of Cuj sites was also investigated by various catalyst characterization methods including TGA, TPSR, Raman and XAS. 

There is increasing interest in the degree of fractionation which occurs from the bulk solvent to the solvation sphere of solutes but at the moment even in fields of strong interaction (e.g. Ni " in DMSO-H2O mixtures) no technique appears sufficiently definitive, although high precision NMR studies have produced promising results. ... 

The fact that procainamide can be photocomplexed to DNA in vitro is an interesting observation. If a procainamide-DNA complex is the form of the complete antigen in vivo, then the antibodies should have limited cross reactivity with native DNA. This, indeed, appears to be the case no antibodies to native DNA have been found in patients with procainamide-induced lupus (Blomgren and Vaughan 1970 Koffler et al. 1971). Moreover, it would be expected that, if the mechanism for procainamide lupus is centered around a drug DNA complex and no similar complex is demonstrable for hydralazine, DNA antibodies might be likely to occur in patients with hydralazine lupus. Hahn et al. (1972) and Blau (1973) have reported DNA antibodies in hydralazine-treated patients, but the data are not sufficiently definitive to be conclusive. 

In the ideal beam experiment (see Fig. 1), both reagents are in the form of beams having precisely defined and selected identities, internal states, orientations, and velocities. Products are determined as to their identity, velocity, distribution of internal energy, orientation, and angular distribution. Such a supermachine may never be constructed, and indeed will probably not be necessary, as much less detailed information can usually provide a sufficient definition of the mechanisms involved. 

In addition to the standards for procurement> fabrication, erection and testing set forth In the design codes previously cited, a number of supplementary requirements In the form of Standard N Sections prepared for the reactor project were used to govern the quality of specific components, materials, and joints, and to ensure that the methods of testing would be sufficiently definitive to provide the necessary degree of quality control ... 

Sufficient definition for the application. The designer must consider — nature of the gas (e.g., molecular weight single gas or a mixture)... 

Recently, CF transitions have been reported in the antiferromagnetic tetragonal system UPt2Si2 by Steeman et al. (1988). It remains to be seen whether these CF transitions stand up to the test of time, and this material is eompletely localized as in the case of UPd3 (see sect. 2.2.2), or if they are later assigned to phonons. We do not believe that one experiment with a triple-axis spectrometer and a polycrystalline sample is sufficiently definite. The Q dependence of phonons with such a technique is by no means straightforward, especially at small Q. 

To obtain a rate constant for a reaction, a measure for the extent of reaction must be obtained. Usually, the molecular weight at any instant, or a property related to it such as intrinsic viscosity, Mooney viscosity, or plasticity, has been plotted versus time. These techniques, however, are not sufficiently definitive since they depend not only on the average molecular weight but also on molecular weight distribution which may change during mechanochemical reactions (see Section D.2 of this chapter). Researchers at NRPRA defined an efficiency of mastication as the ratio of the number... 

A basic event is the limit to which the failure logic can be resolved. A basic event must have sufficient definition for determination of an appropriate failure rate.
