LOGIC method

In principle it is possible to employ physical, microchemical and biological-physio-logical methods for detection in TLC (Fig. 2). 

The OAET is a logical method of structuring information concerning operator actions resulting from a particular initiating event. 

As we ve mentioned before, the interpretation of NMR spectra is often made complex by the sheer quantity of information that you are confronted with. This is every bit as true for carbon NMR as it is for proton and when you combine the two, that huge pile of information just gets bigger... More important still then that you approach the pile in a logical, methodical manner. 

Results obtained from a given set of measurements that scatter in a random manner are adequately treated by most logical methods of statistics. 

Many optimization strategies are available for the separation of different racemates, both from retailers and from research groups. However, the method development for new drug compounds will remain, at least part, trial and error, until more general phases have been designed that include a more logical method development.

The interaction between solvents is important. For example, the development of a successful crystallization process for purification and isolation of an organic compound requires the selection of a suitable solvent or solvent mixture to date, no logical method has been estabhshed for determining the best solvent combination. The process chemist or engineer often employs a trial-and-error procedure to identify an appropriate solvent system, the success of which is dependent on experience and intuition. One approach utilizes a group-contribution method (UNIFAC) to predict a...

One cannot predict the number of isomers by mere inspection of the molecular formula. A logical method runs as follows. First write the different bonding skeletons for the multivalent atoms, in this case the three C s and the O. There are three such skeletons ... 

Although no direct evidence was found in the cobalt-N-hydroxyethylethyl-enediamine reaction that an oxygen-cobalt addition complex was formed, it seems reasonable to postulate that such an intermediate is present in the reaction. An oxygen-cobalt complex intermediate appears to afford the most logical method of explaining the evidence that the oxidation of cobalt (II) to cobalt (III) occurs in conjunction with the oxidative cleavage of the carbon-carbon bond of the hydroxyethyl group and the formation of ethylenediamine. 

Since unspent calcium carbide is what causes the slag to be classified as reactive, a logical method of eliminating the hazardous characteristic would be to control the process better in order to completely react the calcium carbide with the sulfur in the metal. 

LOGIC Method The local-to-global-information-construction (LOGIC) method [32] has been applied to the estimation of the density of alkanes at 25°C. In this method the groups are atom-centered substructures, FRELB (fragment reduced to an... 

Application of the LOGIC method is demonstrated in Figure 3.4.1 with 3,8-diethyldecane. The estimated density is 0.7740gem-3. Experimental values of 0.7770 and 0.7340gem-3 are known at 20 and 80°C, respectively [34], Interpolation yields a value of 0.7732gem-3 at 25°C, which compares favorably with the estimated value.

Most systems involve several interconnected feedback loops. Such systems cannot be analyzed seriously without a proper formalism, but their detailed description using differential equations is often too heavy. For these reasons we (as many others before) turned to a logical (or Boolean) description, that is, a description in which variables and functions can take only a limited number of values, typically two (1 and 0). Section II is an updated description of a logical method ( kinetic logic ) whose essential aspects were first presented by Thomas and Thomas and Van Ham.2 A less detailed version of this part can be found in Thomas.3 The present paper puts special emphasis on the fact that for each system the Boolean trajectories and final states can be obtained analytically (i.e.,... 

Fig. 1. The double cycle system synthesized by a logical method (see Table II), then translated into a continuous description. Taking into account the fact that we took the k and 0 = 1, the equations used are...

Since it has been shown that the degradation of the pit membranes in wood is the most logical method of increasing permeability, fungi must be capable of attacking this structure in order to be successful. 

This approach may be applicable in solving questions of archaeological dating and relative stratigraphy at sites where traditional pedo-logical methods are inadequate. 

The dilution effect seems to be fairly characteristic of the ozone action upon autoxidation. The logical method of investigation would be to use oxygen-ozone mixtures in all proportions, including mixtures having exceedingly low concentrations of oxygen.
