Variables undefined

The Index n = k- ) - M + m is the current variable that indicates the sequence for the beam projections. Exploiting the current measurings y fn) one has to estimate the unknown image parameters a, with undefined conditions about their distribution and the noise FDD function. 

For each test T let TRUE(T) and FALSE(T) be new variables and ct a new address for the locator S. Let EMPTY be a new variable whose value is always A, undefined. 

It is important to note that not all of the variability in Lp(a) levels can be explained by isoform size variability in Caucasians, only 40-70% of the variation results from differences in the numbers of kringle IV repeats in the gene (B15, B16). Interindividual variation (—22%) also occurs as a result of as yet undefined cis-acting sequences at the apo(a) locus (B15). In some cases, unrelated individuals with the same-sized apo(a) gene and protein have been shown to possess markedly different plasma Lp(a) concentrations (B15, L5) within families, however, the relationship between apo(a) gene size and plasma Lp(a) con-... 

The selection of appropriate microorganisms is a possible way to improve the correlation between BOD and BODj [16,53]. The prerequisite for the use of microorganisms for BOD-sensors is a wide substrate spectrum. Therefore several samples of activated sludge from different wastewater plants were investigated [ 13,14]. One problem with an activated sludge based biosensor is the variability of sensor response with time. These BOD-sensors with an undefined variety of microbial species revealed no reproducible results. For that reason, BOD-sensors were developed using various types of defined cultures of microorganisms (Table 1). 

The natural occurrences of montmorillonites are varied and complex, as is the mineralogy of this mineral group. They are particularly variable chemically, due in part to the completely undefined interlayer ion position which can be occupied in part or entirely by almost any cation except silicon. Definitions and descriptions of these expandable minerals are necessarily vague since the response of these interlayer ions to different chemical and thermal treatments is the most current method of identification for minerals in the group. This leaves the basic 2 1 structure identified in many cases. A broad differentiation of the basic... 

MATLAB m files can contain any number of MATLAB commands. They are handy for long sets of MATLAB instructions or data and afford easy repeated use and easy modification. There are two kinds of MATLAB m files function and script m files. Script m files such as poly9. m on p. 28 use the data that is defined inside of them and any undefined data is taken from the data (with the proper name) that is currently active on the workspace look at the top left window commonly displayed on the MATLAB desktop for a list of defined variables and their type. Script files overwrite the workspace data as instructed in their code. 

Not all published and widely accepted thermodynamic values are reliable. Nordstrom and Archer (2003) provide a detailed review of the controversies, uncertainties, and problems related to thermodynamic data for arsenic and its compounds and aqueous species. Many of the data are contradictory and the methods that produce the data are sometimes questionable or have not been thoroughly documented. Too often, data in the literature have been passed from reference to reference without critical evaluations. Some of the data have high measurement errors, were produced under undefined or poorly defined laboratory conditions, and involved unrepresentative sampling (Matschullat 2000, 298 Nordstrom and Archer, 2003). Furthermore, other questionable data originate from obscure documents or are written in languages that many individuals cannot read and properly interpret. Therefore, thermodynamic results must be accepted with a certain amount of caution. The table in this appendix includes thermodynamic data from various sources, which provide users with some idea of their variability. Although sometimes unavoidable, users... 

Nonylphenol, a product of Union Carbide, Canada Ltd., consists of a mix of p-substituted monoalkyl nonypbenols, (randomly branched), with approximately 3% of the o-isomer and 4% dinonyl-phenol also represent. Apart from Dowanol, all the adjuvants mentioned contain minor variable amounts of undefined contaminants which are a function of the well head source and batch from which they were distilled (Aerotex, Cyclosol) or the method of synthesis (Atlox and nonylphenol). These chemicals and related compounds are also widely used in a wide range of household products including detergents, cleaners, shampoos, foods and other consumer and commercial products. 

The inescapable variability of the source material and potential threat to safety due to unrecognized infectious agents [transmission ofAIDS by blood products and the undefined potential for either human or bovine source materials to spread Creutzfeld-Jakob disease (CJD)/ transmissible or bovine spongiform encephalopathy (TSE, BSE)]... 

One of the problems faced by quantum chemistry is that it is based on a theory borrowed from physics. It therefore is important to note that a given variable or concept may be interpreted very differently in physical and chemical context, respectively. The physicist who is interested in the motion of a molecule in a force-free environment, treats it as a mass point, without any loss of generality. Such a molecule is of no interest to the chemist who studies the interaction of a molecule with its environment. In chemical context the size and shape of the molecule, left undefined in theoretical physics, must be taken into account. The interaction between mass points can simply not account for the observed behaviour of chemical substances. 

Applications of the above type are rather trivial. We may, however, submit more sophisticated questions, as for example Is there a compound that in system ta has a hrf value of 25 . PROLOG uses the convention that a string beginning with a capital letter represents a variable. Initially a variable represents a yet undefined object. During the reasoning process an object might become associated with this variable, i.e. the variable becomes instantiated. Thus, if we ask... 

The only undefined step in the calculation sequence proposed above is the correction of the independent variables in step f. A linear correction process is given by... 

There are inherent limitations in any statistical approach to studying controls on trace metal concentrations in organisms. Cross-correlations -with undefined variables or spurious correlations vithin a data set are always possible. We have minimized those possibilities by studying two very different systems and a wide range of conditions within one of the systems. Nevertheless, precise determinations of the interacting effects of various substrates and the effects of other controls on Zn concentrations in deposit feeders must await further study in both the field and laboratory. We have attempted to point out specific questions such studies might address.
