INDEX conservation

The splitting of a SL into several SLs is regirlated by a fundamental topological theorem proved by Gomes [55-57, 93] in the form of an index conservation constraint. Recall that, according to footnote 3, the index of a saddle (vortex) line is — 1 (+1). When an SL of index rp splits into m new lines, the sum of the indices of the SLs which emerge from the branching point must satisfy the condition...

This means that the discrete solution nearly conserves the Hamiltonian H and, thus, conserves H up to 0 t ). If H is analytic, then the truncation index N in (2) is arbitrary. In general, however, the above formal series diverges as jV —> 00. The term exponentially close may be specified by the following theorem. 

The UL uses RTIs as a guideline to qualify materials for many of the standard appliances and other electrical products it regulates. This testing is done in a conservative manner qualified by judgments based on long experience with such devices UL does not apply indexes automatically. In general, these RTIs are very conservative and can be used as safe continuous-use temperatures for low-load mechanical products. 

The first term in constant phase of E(r. z) that arises from the refractive index of the medium through which the beams propagate. The second term vanishes because of conservation of momentum in the harmonic generating medium. The third term is the Gouy phase, which changes by (n — m) n as the beams pass through a focal point.

We have developed a common residue numbering scheme that facilitates comparison of the sequences of different NTs. The numbering scheme is informative of the relative position of each amino acid, the amino acid present at that position, and the actual amino acid number in a particular transporter. Each index number starts with the number of the transmembrane segment (TM), e.g., 1 for TM1, and is followed by a number indicating the position relative to a reference residue that is the most conserved position in that TM. That reference residue is arbitrarily assigned the number 50. For exam-...

An approach to the calculation of conservation has been proposed on the basis of the polytope-method and the information content (4,6). Briefly, the degree of conservation at each position in the alignment is determined by the number of different amino acids, the probability of finding a particular residue replaced by another, and the frequency of appearance of each type of residue. These factors are integrated to calculate the conservation index (Cl). 

The ability of the liver to act as a depot for vitamin Bi2 (B28, G13) enables us to use this vitamin as an index of proper hepatic function. Hepatic disorders lead to an increased Bi2-binding in the serum (J5, R3), suggesting that the blood assumes a greater role in the conservation of B12. We have reported that patients with liver disease excreted invariably less than 10 fig of Bi2> 8 hours after a 50-[ig intramuscular load dose of the vitamin. In contrast, normal subjects excreted 24-40 pg, i.e., 50-80% of the vitamin in the same test (B14). These results were correlated with various chemical determinations indicative of hepatic disorders (Bl). In Table 16 the clinical diagnosis and the various liver-... 

The use of a new statistical approach, the limiting distribution, which is based upon the assumption of lognormality, generally leads to correct conclusions on the basis of few samples relative to the number required by tolerance sets. Limiting distributions may also be indexed to the toxicological and environmental realities so that they can be made as conservative as desired. 

Basic Equations We make following assumptions that 1) the mass loss occurs steadily and 2) the flow is polytropic with index n within the secondary. In these assumptions, the energy conservation is given by... 

Use of systematic nomenclature is a bit like energy conservation—we all recognize it is necessary, but we would just as soon the start be made after we are dead. The phenomenal growth of organic chemistry during the past decade and the switch by the indexes of Chemical Abstracts to use much more systematic nomenclature suggests that the right time is now. The approach we will take in this book to the nomenclature problem is described in more detail in Chapter 3 (pp. 49-51).
