Delimiter

The region of coexistence between liquid and gas phases is delimited by three curves ... 

The aim of defect segmentation is to delimit the detected defect as precise as possible from the background which surrounds the defect (fig. 8). The extracted characteristics of a detected casting defect depend considerable on the threshold value which is used during the defect segmentation. 

Cooccurrence matrix is divided into four bloeks delimited by a threshold t (fig.3). In the block Bl, the included coefficients belong to the background of the image. In the block B4, the coefficients correspond to the objects of the image, and finally, the blocks B2 and B3 contain the coefficients linked to the transitions between background and objects. 

Figure C2.1.10. (a) Gibbs energy of mixing as a function of the volume fraction of polymer A for a symmetric binary polymer mixture = Ag = N. The curves are obtained from equation (C2.1.9 ). (b) Phase diagram of a symmetric polymer mixture = Ag = A. The full curve is the binodal and delimits the homogeneous region from that of the two-phase stmcture. The broken curve is the spinodal.

Therefore, the locus of the values ( ) with a vanishing second derivative of A delimits the region of the miscibility gap in which spinodal decomposition occurs. This locus is referred to as the spinodal (figure C2.1.10 (bl). The length scale of the concentration fluctuations at the beginning of the separation process is controlled by... 

Criteria for mechanical delimitations in samphng by the alternative cross-stream method to fulfih through-stream extraction requirements are revised from gravity-sampling criteria in the following respec ts ... 

Repeating an axiom stated earher, mechanical samplers are designed to extrac t increments of sample from a bulk quantity of material B in a manner that increments S are representative within statistical bounds of the bulk B. Further, the sampler is designed and constructed in conformance to criteria stated previously under Mechanical Delimitations of Sampling to assure that negligible errors arise from mechanical influence. 

A second problem concerns delimiting the mechanisms of action which should be included in the definition, to exclude effects which are a secondary consequence of overt toxicity in other body systems. For example, disruption to the endocrine system caused by general metabolic disturbance, such as in severe liver damage, should not be grounds for calling a chemical an ED. 

In equation (10.2) / is a delimiter. Hence the numerator of each term is the membership value in fuzzy set M associated with the element of the universe indicated in the denominator. When = 11, equation (10.2) can be written as... 

After selecting the MEX command (selection 5) the comma delimited input consists of groups of basic events that are pairwise mutually exclusive. To extend the group to the next and subsequent lines, the first field must be blank. Up to 100 names per group are allowed with a new group starting when a non-blank character is encountered in the first field. The number of pairs that are mutually exclusive is n /[(n-2) 2 ], where n is the number of basic events in the group. An example for the plant blackout fault tree is DG-A-M,DG-B-M,DG-C-M (where means enter). 

The programs were written for a main frame computer using card input. To make the set of codes easier to use, I wrote auxiliary codes to organize the procedures and permit the user to provide input in comma-delimited format. This organizes the deck input and assures proper column placement of the data.

Selection 6 (Figure A-4) executes the SUB command. The comma-delimited input alternates... 

Materials, such as activated carbons, that are derived from natural products differ greatly in their effectiveness when used as catalyst supports, but it is difficult to delimit the factors present in the carbon that influence performance, Certain broad statements, such as that carbons with excessive sulfur or ash content tend to make inferior catalysts, only begin to touch on the problem. One of the advantages of buying commercial catalysts, instead of using laboratory preparations, is that commercial suppliers have solved this problem already by empirical testing of many carbons. They provide catalysts that are best by test. 

Query 2 an aromatic group and a hydrogen-bond acceptor center. R1 is a complex generic group (not detailed here) which delimits the search to all groups that provides lone-pair electrons to the hydrogen bond.

Obviously, one looks for causes. That declines in one or another species have natural factor etiologies is unequivocal. The demise of American elms and of the chestnut were due to natural factors. Insect infestations, bacterial and fungal diseases, hurricanes, floods, freezes, droughts and many other stresses can cause extensive tree death (5). But in such declines typically only a single species is affected or climatic events caused decline in a delimited area. In almost all declines caused by natural events, the causal factors can be identified we know their precise etiologies. Natural events are always part of the natural environment and must be factored in when evaluating forest declines (Table I). 

It will not be easy to shoehorn all of these elements into a 4-year program, and the initiation of carefully delimited electives and options for students is probably the best approach. The coimnittee applauds the recent action of the AlChE to allow more flexibility in the choice of science electives by undergraduates in accredited departments. The development of such electives and new course sequences is not a casual undertaking. It will require greater involvement by faculty in providing advice and counsel to students at the sophomore and junior level, who may not be prepared to make definitive choices about specialization in their major. 

Tervalent organophosphorus compounds containing one single P-N bond with the valency of each atom saturated by protons or carbons (but no other heteroatoms) have been known since their discovery by MichaeUs more than one century ago [ 1 ] and named indistinctly as aminophosphanes, phosphanamines, phosphazanes, or phosphinous amides. This last chemical nomenclature is the one used by the Chemical Abstracts Service (CAS) for indexing these compounds and is also the one that best delimits the scope of this review those species derived from the parent H2P-NH2 (phosphinous amide in CAS nomenclature) by partial or total substitution of protons by hydrocarbon radicals (Table 1).
