    Time dependent model for hemoglobin and allosteric enzymes. II. (1971)

    Notes: The time-dependent theory developed in Part I is specialized to treat tetrameric hemoglobin, and the results of the theory for dimeric-and tetrameric hemoglobin are compared with data on the kinetics of the reactions of hemoglobin with carbon monoxide and oxygen at various salt concentrations for the case of large concentration of ligand relative to that of hemoglobin. The fit of the theoretical results to the data suggests that hemoglobin at a 2 M salt concentration is predominantly dimeric and that the tetramer should be taken as the functional unit to explain the kinetics of the reactions of normal hemoglobin. A relationship is established between the time-dependent theory arid Adair's Intermediate Compound Hypothesis (I.C.H.) for hemoglobin, as brought to its present state by Gibson and Roughton. A generalization (G.I.C.H.) of the I.C.H. is presented and is shown to be equivalent to the time-dependent theory in the limit of infinite ligand concentration. The I.C.H. is shown to be an excellent approximation to the centralized theory (G.I.C.H.) in this limit.

    Time-dependent model for hemoglobin and allosteric enzymes. I. General formulation (1971)

    Notes: A previous equilibrium model is generalized to study time-dependent behavior of hemoglobin and allosteric enzymes. An exact solution for two interacting subunits (e.g., diheme) is given, and a general method for solving the resulting set of differential equations is outlined. At half saturation (equilibrium) concentration, the model takes a particularly simple form which suggests an experiment to determine the number of subunits of an allosteric enzyme, or in particular to distinguish diheme from ordinary hemoglobin. The relation between the present model and other kinetic models is also discussed.

    Elasto visco-plastic flow with special attention to boundary conditions (1981)

    Notes: In this paper we analyse a simple but non-trivial steady-state creeping elasto visco-plastic (Maxwell fluid) radial flow problem, paying particular attention to the effects of the boundary conditions. Solutions are obtained by integration of a governing equation on stress, using the Runge-Kutta method for initial value problems and finite differences for boundary value problems. A more general approach by the finite element method, which solves for the velocity field rather than the stress field, and which is applicable to a wide range of problems, is presented and tested using the radial flow example.

    A high order finite element for completely incompressible creeping flow (1973)

    Notes: A finite element method for simulating the creeping flow of an incompressible material is presented. The method allows for (1) a quadratic approximation of the velocity field, (2) material incompressibility everywhere within an element and (3) the ability to follow the flow through large changes of the material boundaries. A candle slowly bending under its own weight is simulated for illustrative purposes.

    Notes: A frontal-skyline method is presented which allows for compact skyline storage while using the frontal method. It is shown that the method requires the same minimum core storage as the frontal method and fewer transfers to and from disc than the blocked-skyline method. Subroutines necessary for its implementation with finite element codes are given.

    Notes: An apparatus was constructed which would allow vinyl-type monomers (and others) to polymerize at ambient temperatures in the presence of an inductively coupled RF field. The details of the construction of the system are reported along with preliminary results obtained from nine monomers: styrene, methylvinyldichlorosilane, vinyl acetate, acrylonitrile, vinyl fluoride, 1,1-difluoroethylene, vinyl chloride, ethylene, and 1,3-butadiene.

    Notes: A study has been made on the plasma polymerization of styrene monomer in a cold, low-power, inductively coupled RF plasma. Styrene monomer yielded an insoluble, crosslinked film which was slightly colored. A kinetic study is reported for styrene. The effects of power level, bleed rate of monomer, pressure, and reactor geometry on the rate of polymer formation are reported. A mechanism is postulated for plasma polymerization. It was found that the initiation step was the rate controlling step and that the reaction followed a cationic polymerization scheme. Both crosslinking and discoloration of the polymers occur at the time of polymerization and are not a result of exposure of the reacted polymer to the plasma. The polymerization was shown to take place in the bulk phase as well as on the reaction wall surfaces.

    Particle size dispersion during latex growth (1982)

    Notes: The evolution of the latex particle diameter distribution during batch emulsion polymerization is investigated, with emphasis on changes in the breadth of the size distribution. A model utilizing a surface area-dependent volumetric growth rate of a single particle results in a time-invariant standard deviation of the size distribution during periods of particle growth only. This behavior is reconciled with some experimental observations by considering the occurrence of particle nucleation during some part of the growth interval. Conclusions based on the results of the model suggest that higher inhibitor and low emulsifier concentrations favor narrow particle size distributions.
