    Diffusion from spheres in a continuous-flow stirred tank (1990)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 36 (1990), S. 1011-1016

    ISSN: 0001-1541

    Notes: Solvent diffusion from spheres at constant mass-transfer Fourier number, FoM, in a single continuous-flow stirred tank (CFST) and in a series of CFSTs is simulated. A transfer efficiency is defined and transfer efficiency curves are constructed as a function of FoM and the residence time distribution of the spheres in the system. The fraction of solvent removed from the spheres in a series of CFSTs can be approximated using the transfer efficiency curves and knowledge of the operating conditions in each tank. The usefulness of the curves to predict solvent removal from polymer spheres under pilot-plant conditions is examined.

    The frequency domain evaluation of mathematical models for dynamic systems (1967)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 13 (1967), S. 374-378 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: An important problem in the mathematical modeling of dynamic systems is the testing of model applicability and the determination of the best model parameters through the minimization of the squared difference of the observed and predicted responses. This paper discusses the advantages of the transformation of the expression for the integral of the squared deviations φ to the frequency domain by the use of parseval's theorem. Two important advantages of the minimization of φ in the frequency domain are the ease with which the transform of the predicted response can be obtained and the algebraic nature of frequency domain operations. Other advantages are discussed and techniques for the numerical transformation and inversion of the observed and predicted responses are given.

    Notes: The reduction of [L2TiCl2] (1) (L = 3,5-tert-butylpyrazolate) with 1% Na/Hg in tetrahydrofuran (THF) affords the complex [L2TiCl(THF)2] (2), which crystallizes from hexane in moderate yield. The analogous reduction carried out in toluene gives dimeric [(L2TiCl)2] (3) in high yield. If the reduction time is extended to 3 days, the complex [L3Ti] (4) is isolated as light blue crystals in low yield. An alternative procedure for preparing compound 4 requires mixing [TiCl3(THF)3] with 3 equivalents of potassium 3,5-tert-butylpyrazolate in toluene. Crystallization from hexane affords 4 in high yield. Crystallographic data for 2, 3 and 4 are presented.

    Notes: We have measured the solubility of mixtures of polybutadiene and polystyrene in toluene, benzene, and carbon tetrachloride, using polymers of various molecular weights and mixed in various proportions. The equations developed by Maron for solutions of nonelectrolytes have been modified for three components and for solutions of low molecular weight polymers at high concentrations. The application of these equations has provided estimates of the polymer-polymer interaction parameters χ23. The polymer-solvent interaction parameters χ12 and χ13 apparently are functions of the concentration and are not readily obtained from the present limited data.

    Notes: The purpose of this review on spectrin is to examine the functional properties of this ubiquitous family of membrane skeletal proteins. Major topics include spectrin-membrane linkages, spectrin-filament linkages, the subcellular localization of spectrins in various cell types and a discussion of major functional differences between erythroid and nonerythroid spectrins. This includes a summary of studies from our own laboratories on the functional and structural comparison of avian spectrin isoforms which are comprised of a common alpha subunit and a tissue-specific beta subunit. Consequently, the observed differences among these spectrins can be assigned to differences in the properties of the beta subunits.

    Contributions of the β-subunit to spectrin structure and function (1989)
    New York, NY : Wiley-Blackwell
    Cell Motility and the Cytoskeleton 12 (1989), S. 248-263

    Notes: The three avian spectrins that have been characterized consist of a common α-subunit (240 kD) paired with an isoform-specific β-subunit from either erythrocyte (220 or 230 kD), brain (235 kD), or intestinal brush border (260 kD). Analysis of avian spectrins, with their naturally occurring “subunit replacement” has proved useful in assessing the relative contribution of each subunit to spectrin function. In this study we have completed a survey of avian spectrin binding properties and present morphometric analysis of the relative flexibility and linearity of various avian and human spectrin isoforms. Evidence is presented that, like its mammalian counterpart, avian brain spectrin binds human erythroid ankyrin with low affinity. Cosedimentation analysis demonstrates that (1) avian erythroid protein 4.1 stimulates spectrin-actin binding of both mammalian and avian erythrocyte and brain spectrins, but not the TW 260/240 isoform, (2) calpactin I does not potentiate actin binding of either TW 260/240 or brain spectrin, and (3) erythrocyte adducin does not stimulate the interaction of TW 260/240 with actin.In addition, a morphometric analysis of rotary-shadow images of spectrin isoforms, individual subunits, and reconstituted complexes from isolated subunits was performed. This analysis revealed that the overall flexibility and linearity of a given spectrin heterodimer and tetramer is largely determined by the intrinsic rigidity and linearity of its β-spectrin subunit. No additional rigidity appears to be imparted by noncovalent associations between the subunits. The scaled flexural rigidity of the most rigid spectrin analyzed (human brain) is similar to that reported for F-actin.

    Studies on the metabolism of omeprazole in the rat using liquid chromatography/ionspray mass spectrometry and the isotope cluster technique with [34S] omeprazole (1992)

    Notes: This paper describes the application of the ionspray (pneumatically-assisted electrospray) interface for liquid chromatography (LC) and atmospheric-pressure ionization mass spectrometry (API MS) to samples obtained in a study on the metabolism of omeprazole. In this study [34S]omeprazole was utilized for the stable isotope cluster technique. Over forty metabolites in a sample of partially purified rat urine were resolved by gradient elution LC with ionspray API MS detection, and each of them produced molecular ion 1:1 clusters (MH+ and [MH+2]+). The Chromatographic fidelty of the total-ion current (TIC) was excellent. The endogenous matrix of the sample was quite low, allowing a background-substracted averaged mass spectrum of the entire TIC trace to produce a ‘metabolite mass profile’ depicting all the molecular ion 1:1 clusters in the sample. From this mass profile, it was possible to obtain direct information concerning oxygenation an conjugation reactions of the parent compound.
