    Notes: It is supposed that most readers of The Journal of Modern African Studies know something of A.M.S.A.C., its origins, and the programmatic implementation of its purposes; if not, then certainly of its existence. Accordingly, only a summary recapitulation of the Society's history of origin will be made here.

    Architectural research quarterly 2 (1996), S. 84-90 
    Details
    ISSN: 1359-1355

    Topics: Architecture, Civil Engineering, Surveying
    Notes: This paper explores thermal comfort, following recent renewed interest in thermal comfort standards. It also reports on findings from the Thermal Comfort Task in the EU funded PASCOOL project which had an overall objective of promoting passive cooling and avoiding air conditioning. Finally, some tentative conclusions are developed together with their implications for architectural design.

    An experimental investigation of air bubble motion in a turbulent water stream (1965)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 11 (1965), S. 268-273 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: The motion of individual air bubbles in a water stream flowing turbulently in a 4 in. × 4 in. vertical conduit is investigated by photographic means. The bulk water velocity ranges from 40.8 to 267 cm./sec., corresponding to a system Reynolds number range of 48,600 to 386,000. Both tap and demineralized water were used at or near room temperatures. Air bubbles range from 0.038 to 0.70 cm. in equivalent radius and the corresponding bubble Reynolds number based on relative velocity ranges from 58 to 4,500.The results indicated that the bubble relative velocity in a turbulent water stream is similar to the rise velocity of single bubbles through a quiescent liquid. It was found to be practically independent of the system Reynolds number for bubbles having an equivalent radius above 0.3 cm. Large fluctuations in the bubble velocities were noted in all cases. The drag coefficient is, in general, lower for the demineralized water tests than for tap water when the bubble Reynolds number is below 2,000. Above this value, a mergence of the drag coefficients for all tests occur with a peak of approximately 2.0 at a bubble Reynolds number of 3,000, which is lower than the nonflow value of 2.6.

    Heat transfer in a fuel cell battery (1965)
    Hoboken, NJ : Wiley-Blackwell

    Notes: Analytical solutions were obtained for temperature distributions in a single adiabatic fuel cell with heat generation by TΔS, I2R, and polarization. With these results it is possible to characterize heat transfer in a battery with convection in the fuel and air streams, and with conduction of heat in three directions, by means of an average temperature for which an analytical solution was also obtained. Although the temperature can be kept within safe limits in low-power density batteries, the results show that critical dimensions exist beyond which failure by thermal buckling will occur.

    A mechanistic investigation of the microbial chiral inversion of 2-phenylpropionic acid by Verticillium lecanii (1997)
    New York, NY [u.a.] : Wiley-Blackwell
    Chirality 9 (1997), S. 254-260 
    Details
    ISSN: 0899-0042
    Keywords: microbial chiral inversion ; 2-phenylpropionic acid ; kinetic isotope effect ; Chemistry ; Organic Chemistry

    Topics: Chemistry and Pharmacology
    Notes: Previous investigations have described the development of nongrowing suspension of Verticillium lecanii as a microbial model of the mammalian chiral inversion of the 2-arylpropionic acids (2-APAs). Mechanistic studies in mammals have shown that inversion involves loss of the α-methine proton but retention of the original atoms at the β-methyl position, and a mechanism has been proposed involving enzymatic epimerisation of acyl-CoA thioester derivatives of the substrate. Inversion of the 2-APAs by V. lecanii exhibits extensive intersubstrate variation in the presence, rate, extent, and direction of inversion, which are different from those observed in mammalian systems, possibly indicating differences in the mechanism of inversion between mammalian and microbial cells. This study involved the investigation of proton/deuterium exchange by 1H-nuclear magnetic resonance following incubation of deuterated derivatives of 2-phenylpropionic acid (2-PPA), a model compound, in cell suspensions of V. lecanii and incubation of undeuterated 2-PPA in cell suspensions containing D2O. The results indicated that the inversion of 2-PPA by V. lecanii also involved exchange of the α-methine proton but complete retention on the original atoms at the β-methyl position. No kinetic deuterium isotope effect was observed, indicating that loss of the α-methine proton is not the rate-limiting step of the inversion process. This suggests that the observed differences between microbial and mammalian systems probably involve the stereoselective acyl-CoA thioester formation step and not the subsequent epimerisation of the resultant diastereomers.

    Two-step immobilized enzyme conversion of cephalosporin C to 7-aminocephalosporanic acid (1995)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The first large-scale production of 7-aminocephalosporanic acid (7ACA) from cephalosporin C (CPC) using a wholly enzymatic synthesis method is reported here. We produced 7ACA from CPC in as high a molar yield as 85% using the immobilized enzymes D-amino acid oxidase (D-AOD) and glutaryl-7-ACA acylase (GL-acylase). In the first reactor, CPC is converted to keto-adipyl-7-aminocephalosporanic acid (keto-7ACA) using an immobilized D-AOD isolated from a yeast, Trigonopsis variabilis. The keto-7ACA is then spontaneously converted to glutaryl-7-aminocephalosporanic acid (GL-7ACA) via a chemical reaction with hydrogen peroxide. The hydrogen peroxide is also a product of the D-AOD reaction. Near quantitative conversion of the keto-7ACA to GL-7ACA was observed. The second reactor converts GL-7ACA to 7ACA using an immobilized GL-acylase, which was isolated from a reconbinant Escherichia coli. The final 7ACA crystalline product is a high quality product. The reactions are conducted under very mild aqueous conditions: pH 8.0 and 20° to 25°C. The production of desacetyl side products is minimal. This process is currently being implemented on an industrial scale to produce 7ACA. © 1995 John Wiley & Sons, Inc.

    Modified ionspray interface for supercritical fluid chromatography/mass spectrometry: Interface design and initial results (1995)
    New York, NY : Wiley-Blackwell
    Rapid Communications in Mass Spectrometry 9 (1995), S. 1087-1094

    Notes: A pneumatically assisted electrospray liquid chromatography/mass spectrometry interface has been modified for use with open-tubular supercritical fluid chromatography (SFC). The modified interface houses the SFC flow restrictor within the spray device. A sheath-flow liquid of methanol or methanol/water containing ammonium acetate flows coaxially to the restrictor. The addition of the sheath-flow liquid results in the ionization of analytes known to be in a neutral charge state during the chromatographic separation. The sheath-flow liquid also allows for the independent operation of the chromatograph and the mass spectrometer. Both could be operated under optimum conditions. The operation of the interface was optimized using a solution of poly(dimethylsiloxane) in CO2 introduced by continuous infusion. We also report the application of the modified instrument to samples containing amines and propoxylated alcohols.
