    Notes: Leading-order solutions for electron and ion density, electron and ion velocity, and electric potential have been obtained in a planar, symmetric geometry for the case of a dense, low-temperature plasma bounded by perfectly absorbing walls. The solutions are obtained in terms of the Jacobi elliptic functions. These solutions are shown to reduce to those previously obtained for the case of a semi-infinite plasma when the appropriate transformations are applied. The solutions are also shown to reduce to the well-known solutions from linear diffusion theory, in terms of circular functions, when the linear source approximation is made. The solutions are evaluated and discussed for a representative thermal plasma where the influence of explicitly accounting for recombination is illustrated. © 1999 American Institute of Physics.

    Notes: [Auszug] Activation of the nuclear transcription factor NF-κB by inflammatory cytokines requires the successive action of NF-κB-inducing kinase (NIK) and an IκB-kinase (IKK) complex composed of IKKα and IKKβ. Here we show that the Akt serine–threonine kinase is ...

    Notes: [Auszug] Ozes et al. replyDelhase et al. take issue with our claim that Akt induces activation of NF-κB by phosphorylating IKKα, contending that IKKα plays no role in the activation by TNF of NF-κB, and consequently that Akt could not affect NF-κB ...

    Notes: Abstract Growth of Aspergillus flavus and Trichoderma viride on agar media was inhibited around embryos of green peanut seeds but not around embryos of cured seeds, intact peanut seeds, or testae. Both fungi were able to colonize intact seeds and testae. Substances inhibitory to A. flavus and T. viride were extracted with acetone from cotyledons of freshly harvested peanut seeds. Four compounds inhibitory to A. flavus were detected in crude acetone extracts. Three of the compounds demonstrated properties of phenolics. Results of this study suggest that inhibitory compounds in peanut cotyledons may play a role in protecting the peanut embryo from fungal infection.

    Notes: Abstract An inhibitor of Aspergillus flavus has been isolated from peanuts and identified as 5,7-dimethoxyisoflavone. Authentic 5,7-dimethoxyisoflavone, synthesized from benzyl-2-hydroxy-4,6 dimethoxyphenyl (3), and the isolated compound display identical ultraviolet spectra in methanol, in methanol+sodium methoxide, and in methanol+AlCl3; similar behavior in solvent extraction, column chromatography, TLC, and fungal inhibition.

    Notes: Abstract Lindsey recently examined the precision of the manuscript review process using a stochastic model. The study reported that the low reliability found by previous studies results in journals publishing a large number of papers that should otherwise be rejected and rejecting an equally large number of papers that should be accepted.Hargens andHerting have criticized this view. This paper addresses their criticisms. The paper includes an examination of sociology journals usingimpact scores. The differences between journals is noted. Part of the variation between sociology journals derives from their editorial operations. Central to their editorial operations is the reviewing of manuscripts for publication. Not all journals perform this task equally well. The consequences of poor editorial management are discussed. To improve the quality of published work journals need to reduce the low reliability of the current manuscript review process.

    Notes: Conclusion With the research byLong, Allison andMcGinnis, Cole andCole, an-Garfield an initial understanding of the consequences of multiple authorship for empirical studies of science is emerging.9 It is too early to suggest, asLong andMcGinnis do, that indices which disgegard multiple authorship are without serious short-comings. The best advise would be to use measures which take multiple authorship into account, compare them with others that do not, and examine any differences that might emerge. At least for the data will which I have worked, multiple authorship makes a considerable difference. Although little difference is found with the data collected by long and his colleagues when examined within an unclear regression analysis framework, it would seem premature to recommend unadjusted counts. The best advice to the prospective researcher would be to collect complete information on the number of authors for all published work and all citations assuming that difference between adjusted and unadjusted counts will emerge and be comfortable with the knowledge that if it does, the measures used can properly treat the data. The major point I made earlier, that the failure to adjust for multiple authorship is the most serious error in empirical judgment made in the sociology of science, emerges more forcefully. The error will require substantial redevelopment of previous empirical literature constructed with these faulty measures. Finally, the point should not be lost that the most serious problem remains and that is the validity of the “paper model” of science with examines article and citation counts to understand this complex dynamic project of human inquiry.10

    Notes: Abstract Empirical work in the social studies of science has progressed rapidly with the availability and development of the citation indexes. Citation counts have become a widely accepted measure of the quality of a scientific contribution. However, there are several problems involved in the use of citation counts as a measure of quality in science. First, citation counts are sensitive to popular trends in science. In this sense, they approximate a Nielsen rating for science. Second, the distribution of citations restricts their utility to separating the extremes. Third, citation counts are not sensitive to the ethical and moral dimensions of the quality of a scientific contribution. Fourth, citation counts underestimate the contribution of applied scientists. This paper examines these limitations.
