Discrepancies in data

In summary, although there have been contradictory reports in related literature, as well as discrepancies in data from humans and rodents, recent studies point to a higher nicotine metabolism in females than males.

Flash points/flammability data. The flash point of a solvent is closely dependent on the test method used, and this is quoted where available. Due to discrepancies in data, individual values are quoted with the source of the information. Care must be exercised before using these data and the supplier of the solvent should always be consulted. 

Due to the aforementioned discrepancy in data availability (especially relevant to translation of toxic effect) and the fact that many clinical endpoints are multi-mechanistic, it is important to stress that each computational step should be well defined and model small steps, for example, a traditional quantitative structure-activity relationship (QSAR) approach based on chemical structure is probably relevant to distinguish hERG binders from nonbinders, but not relevant to model a small set of diverse compounds associated with a complex endpoint such as drug induced liver injury (DILI). A second important factor to consider when construchng in silico safety models is the intended use of the model, and the potential cost associated with false positives versus false negatives from the model. For instance, there is zero... 

Measurements of sublimation enthalpies and vaporization enthalpies have been made for over a century. .. despite the longevity in interest in these measurements and the significant technological improvements in instrumentation and assessment of purity, examination of recent data still show significant discrepancies in data published by different laboratories and different...

The nature of the termination reaction in MMA polymerization has been investigated by a number of groups using a wide range of techniques (Tabic 5.5), There is general agreement that there is substantial disproportionation. However, there is considerable discrepancy in the precise values of k tk. In some cases the difference has been attributed to variations in the way molecular weight data are interpreted or to the failure to allow for other modes of termination under the polymerization conditions (chain transfer, primary radical termination).154 In other eases the reasons for the discrepancies are less clear. MALDI-TOF mass... 

The instrument has been evaluated by Luster, Whitman, and Fauth (Ref 20). They selected atomized Al, AP and NGu as materials for study that would be representative of proplnt ingredients. They found that only 2000 particles could be counted in 2 hours, a time arbitrarily chosen as feasible for control work. This number is not considered sufficient, as 18,000 particles are required for a 95% confidence level. Statistical analysis of results obtained for AP was impossible because of discrepancies In the data resulting from crystal growth and particle agglomeration. The sample of NGu could not be handled by the instrument because it consisted of a mixt of needles and chunky particles. They concluded that for dimensionally stable materials such as Al or carborundum, excellent agreement was found with other methods such as the Micromerograph or visual microscopic count. But because of the properties peculiar to AP and NGu, the Flying Spot Particle Resolver was not believed suitable for process control of these materials... 

This event is one of the most visible in a study, representing the culmination of efforts spanning months or years and often representing the future of a product or even a company. Locking the database requires that every query and all outstanding discrepancies regarding data be resolved. 

Owing to the very large discrepancies in the data on 7, we have made new computations with other basis sets but with the same process they converge...

For the different values of pAHX and pA H+ see the summary Table 4.5 later of pKa data in various solvents of low e in comparison with pAa(H20). The mutual agreement of pffHX values obtained by spectrophotometry, DVP, potentiometry and titration was reasonably good the typical form of the curves for titration of the dinitrophenols with TMG can be explained by homoconjugation and more especially by its influence on the potentiometric measurements, calculated on the basis of simple dissociation hence the major discrepancies in the spectrophotometric and potentiometric pK values. In order to... 

We present CCD photometry in the Johnson V, Kron-Cousins I and Washington system CTi passbands for NGC2324, a rich open cluster located near the Galactic anticentre direction. We believe that the high discrepancy in the basic cluster parameters derived in previous studies, particularly in the cluster metal content, warrants their redetermination on the basis of more reliable data. 

The discrepancies in the reported conductance data of Au-alkanedithiol-Au junctions attracted our attention, and we decided to carry out an in-depth experimental study of the charge transport properties of Au-a,oo-alkanedithiol-Au molecule junctions in a non-conducting solvent. The combination with quantum chemistry ab initio simulations yielded a detailed view of this archetype of molecular junctions, and helped to resolve the puzzle on the role of microscopic geometries at the contacts and in the molecular conformation.
