    Description / Table of Contents: Zusammenfassung In diesem Bericht ist das Problem der laminaren natürlichen Konvektionsströmung an einem dünnen Kegelstumpf behandelt. Die maßgebliche Differentialgleichung ist durch eine Verbindung von Quasilinearisation und Differenzenverfahren gelöst. Eine numerische Lösung für Pr=0.7 wird für verschiedene Werte eines Krümmungsparameters angegeben. Es ist gezeigt, daß in solchen Strömungen dieser Krümmungsparameter eine große Bedeutung besitzt.
    Notes: Abstract The problem of laminar, natural convection flow over a slender frustum of a cone is treated in this paper. The governing differential equations are solved by a combination of quasi-linearization and finite-difference methods. Numerical solutions are obtained for Pr=0.7 and for a range of values of the transverse curvature parameter. It is shown that the effect of transverse curvature is of great significance in such flows.

    Haemoglobin synthesis in 28 obligatory cases for α-thalassemia traits (1975)

    Notes: Summary In the Far East two types of α-thalassemia genes, namely α-thalassemia1 (α-thal1) and α-thalassemia2 (α-thal2) exist. Definite diagnosis of the α-thal1 and α-thal2 traits is very difficult because their hematological findings are minimally abnormal or normal. This study attempts to characterize the heterozygotes by hemoglobin chain synthesis in reticulocytes from obligatory cases of the α-thal1 and α-thal2 traits. Twelve parents of babies with hemoglobin Bart's hydrops fetalis (obligatory α-thal1 trait) had the mean total radioactivity α/β ratio of 0.76±SD 0.04, while that of 7 normal controls was 1.06±SD 0.04. The α/β globin chain ratios of 16 cases, who were either parents or offspring of patients with hemoglobin H disease, were found to segregate into 2 groups, i.e. 0.78±SD 0.03 (10 cases) and 0.92±SD 0.03 (6 cases), probably representing the α-thal1 and α-thal2 traits respectively. The hematological data of the first group showed definite hypochromic microcytic red cells, similar to thoseof the parents of the hydrops. The second group had significantly higher mean corpuscular hemoglobin than the first group, compatible with α-thal2 trait. Our globin chain synthesis study thus appears to be capable of discriminating normal, α-thal1 and α-thal2 traits.

    Turbulent flow development characteristics in channel inlets (1973)

    Notes: Abstract The turbulent flow characteristics in the inlet regions of circular pipes and parallel plates are considered separately in this paper. The momentum integral equation of the boundary layer near the wall and the overall continuity equation for the flow are solved. The variation of the shape factor is taken into consideration in the solution by supplementing the two basic equations by an entrainment equation. Numerical solutions and available experimental results show that the present theory is in good agreement with experimental data for flow in both pipe and parallel plates.

    Numerical solution of natural convection flow past a non-isothermal vertical flat plate (1977)

    Notes: Abstract The problem of natural convection over a semi-infinite flat plate with non-uniform wall temperature is studied by using a numerical method. The local rates of heat transfer as a function of the distance along the plate are tabulated for a range of Prandtl numbers (0.01 to 100) and for a few cases of wall temperature distributions. Such tabulations serve as a reference against which other approximate solutions can be compared in the future.

    Heat transfer in turbulent pipe flow based on a new mixing length model (1973)

    Notes: Abstract A new model for the heat transfer in turbulent pipe flow is presented based on a modified form of the mixing length theory developed by Cebeci [1] for boundary layer flow problems. The model predicts the velocity and temperature distributions and the Nusselt number for fluids with low, medium and high Prandtl numbers (Pr=.02 to 15) and fits the available experimental data very accurately for values of Reynolds number exceeding 104. Expressions for the eddy conductivity and for the turbulent Prandtl number are presented and shown to be dependent upon the Reynolds number, the Prandtl number, and the distance from the tube wall.

    Notes: The steady state, nonlinear diffusion equations which describe reactions in constrained enzyme solutions are of great interest in many biological and engineering applications. As in other types of nonlinear differential equations, exact analytical solutions do not exist except in some simplified cases. In this paper, a general procedure is presented for solving numerically for the substrate concentration profile and effectiveness factor utilizing the transformation method suggested by Na and Na. Design correlations for enzyme solutions constrained within spherical membranes are included. The use of a unique definition of the Thiele Modulus in these charts permits the clear illustration of the effects of substrate concentration and external mass transfer resistances on the overall effectiveness factor for the catalyst particle.
