    Notes: A consecutive, first-order, irreversible, biochemical reaction, \documentclass{article}\pagestyle{empty}\begin{document}$ A{\textstyle{{k(\theta)} \over {{\rm Enzyme }1}}} \to B{\textstyle{{k(\theta)} \over {{\rm Enzyme 2}}}} \to C $\end{document}, taking place in a series of N reactors with product recycle is considered. A discrete version of the maximum principle is used to derive general equations necessary for maximizing the production of (1) the final product, C, by choosing the temperature or the pH value in each reactor, and (2) the intermediate product, B, by choosing the reactor volume. A numerical computation for a series of three reactors with recycle is illustrated. The effects of varying the recycle rates on the optimal state and decision variables are also presented.

    Notes: Kinetic studies on fermentation processes were made and a general equation of production rate was newly presented applying the kinetic theory on mierobial cell growth which was reported previously by the authors.l,2 Equations for product concentration in fermentation time courses were derived by developing mathematically the general equation of production rate, and characteristic properties of fermentation processes were clarified. Some examples of fermentations were analyzed kinetically using the new kinetic theory. The calculated values of product, and cell concentrations were in good agreement with the observed values.

    Transport of heat and mass between liquids and spherical particles in an agitated tank (1969)
    Hoboken, NJ : Wiley-Blackwell

    Notes: Data are reported for heat transfer from water to melting ice spheres and for mass transfer in the case of dissolving spheres of pivalic acid suspended in water agitated in a stirred vessel. The transport coefficients are found to depend on agitator power input but not on agitator design, in agreement with the Kolmogoroff theory. These experimental results are used with others in the literature to develop a correlation involving Nusselt and Prandtl or Schmidt numbers together with a dimensionless group involving agitation power. The correlation is essentially independent of solid-liquid density ratio in the range 0.8 to 1.25, and in this range the gravity group also appears to be unimportant.

    Copolymerization and terpolymerization in continuous nonideal reactors (1969)

    Notes: A simple means for predicting composition distributions in copolymers is used to illustrate the strong influence of segregation effects in the reactor. A recycle loop reactor can be used to produce uniform copolymers by narrowing the macroscopic composition distribution, but there is a limiting microscopic distribution which results from probabilistic effects.

    The condensation of mixed vapors (1965)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 11 (1965), S. 800-803

    Notes: Although condensation from saturated mixed vapors upon a cold surface has been frequently explored experimentally, current theories describing this phenomenon have not been adequately tested. This work describes the condensation process in which two condensable components are involved and how, consequently, the mass transfer process is involved in their partial fractionation.A discussion of the Bedingfield correction (3) for the effect of molecular weight difference of the diffusing components upon the mass transfer coefficient leads to its necessary association with the Ackermann factor (4, 5) for the general mass transfer effect. Data from two sets of experiments using different apparatuses demonstrate the use of this net corrective factor and also demonstrate the general applicability of the Drew-Colburn mass transfer coefficient, for transfer processes in which more than one component transfers from one phase to another.

    Notes: Heat transfer coefficients have been measured over a range of Reynolds numbers for a solid-vapor mixture of parahydrogen discharging through a heated brass tube below the triple point pressure. A correlation is given which is shown by a formal analysis of a simple model to account for most of the system variables.

    Far-infrared spectra of polyalanines with α-helical and β-form structures (1968)
    New York : Wiley-Blackwell
    Biopolymers 6 (1968), S. 1759-1766 
    Details
    ISSN: 0006-3525
    Keywords: Chemistry ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: Far-infrared spectra of poly-L-alanines having the α-helical conformation and the β-form structure were measured. The spectra of glycine-L-alanine copolymer, silk fibroin, and copoly-D,L-alanines with different D:L compositions were also measured. In addition to the bands so far reported, four bands at 190, 107, 120, and 90 cm-1were found for the α-helix conformation and the two bands at 442 and 247 cm-1 were found for the β form. The 442 cm-1 band consists of the parallel 432 cm-1 and perpendicular 445 cm-1 bands. The 247 cm-1 band is well defined and has strong dichroism parallel to the direction of stretching. These two bands appear also for silk fibroin and glycine-L-alanine copolymer. All the far-infrared bands of copoly-D,L-alanines can be interpreted as α-helix bands, the three peaks at 580, 478, and 420 cm-1 being ascribed to the D-residue incorporated into the right-handed α-helix or to the L-residue in the left-handed α-helix.
