Second-best

Other Metals. Ruthenium, the least expensive of the platinum group, is the second best electrical conductor, has the hardest deposit, and has a high melting point. A general purpose bath uses 5.3 g/L of mthenium as the sulfamate salt with 8 g/L sulfamic acid, and is operated at 25—60°C with a pH of 1—2. Osmium has been plated from acid chloride solutions (130) and iridium from bromide solutions, but there are no known appHcations for these baths. [Pg.163]

Small particle size resins provide higher resolution, as demonstrated in Fig. 4.41. Low molecular weight polystyrene standards are better separated on a GIOOOHxl column packed with 5 /u,m resin than a GlOOOHg column packed with 10 /Ltm resin when compared in the same analysis time. Therefore, smaller particle size resins generally attain a better required resolution in a shorter time. In this context, SuperH columns are best, and Hhr and Hxl columns are second best. Most analyses have been carried out on these three series of H type columns. However, the performance of columns packed with smaller particle size resins is susceptible to some experimental conditions such as the sample concentration of solution, injection volume, and detector cell volume. They must be kept as low as possible to obtain the maximum resolution. Chain scissions of polymer molecules are also easier to occur in columns packed with smaller particle size resins. The flow rate should be kept low in order to prevent this problem, particularly in the analyses of high molecular weight polymers. [Pg.143]

New subsidies often outlive the public policy purpose that they were intended to address. The better-designed subsidies contain sunset provisions that require explicit action to reauthorize them after a certain time. Subsidy and externality policies arc often interrelated. It may be politically difficult to tax an energy source with high external costs, but much easier to subsidize a competing energy source with low external costs. Such second best solutions arc often implemented when political considerations block the preferred option. [Pg.1170]

Systems of two or more hydrocarbon, chemical and water components may be non-ideal for a variety of reasons. In order to accurately predict the distillation performance of these systems, accurate, experimental data are necessary. Second best is the use of specific empirical relationships that predict tvith varying degrees of accuracy the vapor pressure-concentration relationships at specific temperatures and pressures. [Pg.5]

The second best group of connections is defined as those that lie in the unshaded section of the charts on the left. The nearer the connection lies to the reference line, the more desirable is its selection. [Pg.722]

Second best = 7-f in. REG. (low torque). (Light area to left and nearest to reference line.)... [Pg.731]

Good confirmation of these figures is given in Ref. 111. In this evaluation, a sulfosuccinate was run both in the Zein test and in the RBC test. With both results the sulfosuccinate is described as the second best compatible surfactant after a high molecular weight protein fatty acid condensate. [Pg.544]

Testing the robustness of a (best) model (and second-best contenders) by evaluating sets of statistically similar data created with program SIMILAR if the derived decisions remain unaffected by measurement noise, the model is adequate. [Pg.383]

An entry to this network was obtained by starting from 7. The reaction most favored by the reactivity functions leads to 46, but this reaction is endothermic by 17.4 kcal/mol. The second best reaction leads from 7 to 47. In order to explore the chemistry of these systems further, structures 46 and 47 were also submitted to EROS. Starting from 46, the reaction predicted to be the best leads back to 7, the second best reaction to 47. Thus overall, rearrangement of 7 to 47 is expected, with 46 as a potential intermediate of this reaction. The most favored reaction of 47 leads to the cyclopentenone 8, a reaction which is also favored by its exothermicity (—14.8 kcal/mol). The second best reaction leads from 47 to 48. In a further study, 48 was also submitted to EROS. The two reactions evaluated to be best by the present reactivity functions lead to 49 and... [Pg.68]

Second best in their view is the octahedron. However, Alpress and Sanders did not make mention of the cubo-octahedron, which, owing to its smaller surface-to-volume ratio, is probably stabler than the octahedron. Work along similar lines has been done by Fukano and Wayman (17). These authors included only the interactions between nearest neighbors in their considerations however, they also made allowance for the interaction with the substrate by assuming that an atom contacting the substrate is joined to it by two bonds. [Pg.78]

Copper was called cuprum in Latin, hence its symbol, Cu. It is used in the minting of one cent pieces and for pans, but an even more important use is in the wires and switches that carry electricity. Copper is the second-best conductor of electricity (silver is first). It is alloyed with other metals to make bronze and brass. The Cu+2 ion is necessary in the human body, in very small, or trace, amounts, as a catalyst in making blood. At ordinary temperatures, copper is the best conductor of heat. [Pg.57]

By noting that the best conformation will be the one which allows the interaction of the best donor bond (C—Br) with the best acceptor bond (C—Br), the second best donor bond (C—Cl) with the second best acceptor bond (C—Cl), and the third best donor bond (C—F) with the third best acceptor bond (C—F), we predict the best conformation to be I for the meso form. The best conformation for the racemic form will be K, since it is the only one which allows for the interaction of the best donor and best acceptor bonds. We further predict that L will be more stable than J. Experimentally, I and L are found to be the most stable conformations of CClFBrCClFBr371>. [Pg.193]

Next to Fe, Sn is the second best Mossbauer isotope, in the sense that the y-ray energy, Mossbauer lifetime, and parent lifetime are all satisfactory. To use isomer shift measurements eflFectively, one must know the relative change in nuclear radius (8R/R). In the case of Sn, the correct value for this quantity was indefinite, both as to sign and magnitude. [Pg.22]

The resin-bound secondary amides (19-22) are the most difficult to cleave among the compounds studied. Resin (29) was cleaved with 1% TFA in 2 h. Resin (28) was cleaved with 1% TFA in 8 h. Resins (26) and (27) required 5% TFA and 8-15 h. This was the only occasion that linker III was not the most labile bond. Rink linker, the second best in all other series, became the most labile bond. [Pg.519]

TFA). Among various linkers studied in this work, the indole linker [21] was found to be the most suitable linker in terms of cleavage kinetics and actual cost. Rink linker was the second best in term of kinetics. The rate of cleavage of various functional groups linked to the above-mentioned resins was as follows sul-fonamide>carbamate urea>amide. Results from this study demonstrated that optimization of cleavage conditions often led to more suitable conditions and safer release of precious compounds synthesized on a solid support. [Pg.520]

I went over to the desk and penned a quick note, recommending Isaia Modestus of the Ghetto Nuovo as the second-best doctor in Venice. I signed the Maestro s name to it, sealed it with his signet, and took it... [Pg.5]

The concept of the Expert Patient is evolving and companies need to be a ware of these changes and the challenges and opportimities that they pose. Patients demanding the best and not being satisfied with second best can only be a valuable asset to companies introducing innovative new therapies. [Pg.348]
