    Notes: Abstract The binding of α-chymotrypsin to black-eyed pea trypsin/chymotrypsin inhibitor (BTCI) has been studied using the inhibitory activity against the enzyme and the formation of the complex enzyme/inhibitor followed by measurements of fluorescence polarization. Apparent equilibrium constants were estimated for several temperatures and the values obtained range from 0.32 × 107 to 1.36 × 107 M−1. The following values were found from van't Hoff plots: Δ H vh ° = 10.8 kcal mol-1 (from inhibitory assays) and 11.1 kcal mol−1 (from fluorescence polarization); ΔS° = 67.9 and = 67.8 kcal K−1 mol−1, respectively. Calorimetric binding enthalpy was determined (corrected for the ionization heat of the buffer) and the resulting value was ΔH cal ° = 4.9 kcal mol-1. These results indicate that the binding of chymotrypsin to BTCI is an entropically driven process.

    Programmable machine for dialyser reuse (1980)
    Springer
    Medical & biological engineering & computing 18 (1980), S. 765-771 
    Details
    ISSN: 1741-0444
    Keywords: Dialysis ; Dialyser reuse

    Notes: Abstract Because of the high cost of dialysis, many centres have developed methods of cleaning diaylser cartridges so that they may be reused. This paper describes a machine which cleans dialyser cartridges automatically. The main difference between this machine and others reported in the literature is its ability to test automatically for leaks or obstruction and sound an alarm if the dialyser is unsuitable for reuse after the washing process. The development of these tests is decribed in detail. The incorporation of these tests into the alarm system of the machine will make the reuse of dialysers simpler, safer and more consistent.

    Portable microwave test packages for beam-waveguide antenna performance evaluations (1992)
    In:  Other Sources
    Details
    Publication Date: 2011-08-24
    Description: Portable microwave test packages used to evaluate a new 34-m-diameter beam-waveguide (BWG) antenna are described. The experimental methodology involved transporting test packages to different focal points of the BWG system and making noise temperature, antenna efficiency, and holography measurements. Comparisons of data measured at the different focal points enabled determinations of performance degradations caused by various mirrors in the BWG system. It is shown that, due to remarkable stabilities and accuracies of radiometric data obtained through the use of the microwave test packages, degradations caused by the BWG system were successfully determined.
