Informational similarity

In conclusion therefore it may be stated that one must be able to distinguish between motional dispersion and motional homogeneity. Furthermore, a reconstruction of the chemical shift parameters from spectra with MAS at very low temperatures is needed to obtain quantitative motional information. Similar problems to the above also arise in other linear polymers containing interspaced soft and hard segments. 

The idea here was to examine which pair of techniques and individual columns could lead to the best separations in 2DLC. This is achievable by using ID separations and then comparing how the retention of each component varies across the separation space. Another innovation here was the use of IT-derived metrics such as information entropy, informational similarity, and the synentropy. As stated in this paper, The informational similarity of 2D chromatographic systems, H is a measure of global... 

As the science of pharmaceutics grows and matures, the need for information similarly expands along new fronts and causes equivalent growth in the vehicles where investigators find the information they need. The content of the Profiles series has expanded to meet this need, with chapters falling into one or more of the following main categories ... 

Capacitance-voltage (C-V) measurements on Schottky diodes orp-n junctions can provide information similar to that yielded by spreading resistance, namely the net charge density of fixed centers that are ionized in the... 

The language used will be the Queen s English or that subset of it as approved by the Royal Society of Chemistry (RSC). Where chemical names are concerned there are some lost causes, such as caustic soda, where little would be gained if those who clean factories called this substance sodium hydroxide. Arguably, the name caustic soda conveys more useful information. Similar lost causes are spirits of wine (ethyl alcohol or ethanol) and spirits of salts (hydrochloric acid). While lipid chemists may insist on referring to triacylglycerols many people in industry continue to refer to triglycerides. Similarly trivial names for fatty acids such as lauric will continue to be used. The principle in all of this is to use the proper name but to mention other names that are in common use. 

At low hydroxide-ion concentrations, the rate of approach to equilibrium after a temperature jump decreases as the hydroxide-ion concentration increases. At higher concentrations the reaction becomes first order in hydroxide ion. The value of the kinetic solvent deuterium isotope effect on the reaction shows little variation over the range of hydroxide-ion concentrations studied as shown in Fig. 19. The ratio t-1(H20)/t 1(D20) at a particular concentration of OL (L = H or D) remains within the range 2.0 to 3.0 for OL" concentrations of 0.001 to 0.100 mol dm - 3 and provides little mechanistic information. Similar results were obtained in the original work (Perlmutter-Hayman and Shinar, 1978). 

Requests for Cases shall provide a statement of need and background information similar to that defined in paras. VI-3.2 and VI-3.3, respectively, for Code revisions or additions. The urgency of the Case (e.g., project underway or imminent, new procedure, etc.) must be defined. The proposed Case should identify the Code location, and be written in a Question and Reply format. 

For consumer sales of additives sold as such, information similar to labelling particulars for foods generally is required, and for business sales of such additives specific requirements are set out in Directive 89/107/EEC. Labelling requirements for flavourings sold as such are contained in Directive 88/388/ EEC, completed by Directive 91/71/EEC.16... 

The Lab Plan provides information similar to that of the Optimal Plan except that there is the additional constraint of using only the ultracentrifuges and rotors available in the laboratory. This requirement can result in dramatic differences between the Optimal Plan and the Lab Plan. The run times can differ by hours, for example, or the purity of the separation can be significantly affected. A completely different gradient can be recommended as a function of the rotor selected from the lab. If there are no rotors in the lab capable of doing the separation, SpinPro reports that the run cannot be done with the available rotors. 

Other Systemic Effects. Inhalation and/or dermal exposure to diesel fuel has been associated with edema in two individuals (Crisp et al. 1979 Reidenberg et al. 1964). In one of these cases, loin pains, thirst, and severe exhaustion were also reported (Crisp et al. 1979). Several case studies reported fever in children following acute ingestion of kerosene (Akamaguna and Odita 1983 Aldy et al. 1978 Dudin et al. 1991 Mahdi 1988 Majeed et al. 1981 Nouri and Al-Rahim 1970 Saksena 1969 St. John 1982 Subcommittee on Accidental Poisoning 1962). The effects of oral exposure to kerosene in children cannot be used to predict possible effects in adults or the effects of other fuel oils by this route without additional information. Similarly, it cannot be determined whether the effects of diesel fuel noted in humans would occur from exposure to other fuel oils or in the general population since limited information is available.

Eield junction box drawings can range in complexity from a simple cable termination box or cabinet, to a local control station containing electrical/pneumatic equipment. Complex junction boxes may require information similar to that described above for instrument panels (e.g., specifications, drawings, test certificates), depending on the level of complexity involved. 

Despite the extensive photoconductivity data, the nature of photoexcitations in poly(phenylenevinylene), PPV, and its soluble derivatives has remained controversial. In part, the controversy arises from the conflict between the results obtained with fast time-resolved photoconductivity and those obtained by the more familiar steady-state photoconductivity the latter indicate a strong T-dependence for the np product. Recent experiments have resolved the apparent conflict [203]. The idea is rather simple If the sample is sufficiently thin that the photocarriers can be swept out before a significant fraction fall into traps, the steady-state photocurrent will provide information similar to that obtained at short times by transient photoconductivity (in the latter, sample thickness is not important since pre-trapping and trap dominated transport are separated in the time domain). 

An important result of the relaxation studies on Li carried out by Wehrli [9,40] was the finding that an appreciable H, Li nuclear Overhauser effect (NOE) exists which amounts to ti = 2.61 and 1.19 for Li in aqueous LiCl and n-butyllithium in n-hexane, respectively. The theoretical value is Ti=y( H)/ 2y( Li) = 3.40 (Table 1). Due to the inefficient quadrupolar relaxation, the Li nucleus shows considerable dipolar interactions with neighbouring protons which can yield valuable structural information. Similar effects for Li are uncommon because of the stronger dominance of quadrupolar relaxation for this nucleus, but appreciable H, Li NOEs have been found for systems like 7 [37,38].
