    Notes:
    We have investigated the effects of the spin-orbit interaction on the valence-band structure of wurtzite GaN in the k⋅p theory. The spin-orbit interaction is usually neglected in nitrides, which leads to three doubly degenerate bands: the heavy-hole, light-hole, and crystal-field split-off bands. Including the spin-orbit interaction, this degeneracy is removed to give six single bands. We obtained the Luttinger-like parameters in bulk wurtzite GaN by fitting data obtained from an empirical pseudopotential calculation obtaining a value for the parameter A7 of 93.7 meV/Å. We also used these results to calculate the valence-band structures of a GaN/AlGaN quantum well. Our result shows the spin-orbit interaction is important in GaN and associated quantum well structures. © 1999 American Institute of Physics.

    Summary The aeroelastic response analysis of a coupled rotor/fuselage system is approached by iterative solution of the blade aeroelastic response in the non-inertial reference frame fixed on the hub, and the periodic response of the fuselage in the inertial reference frame. A model of the coupled system hinged with the flap and lag hinges, the pitching bearing which may not coincide with the hinges, and the sweeping-blade configuration is established. The moderate-deflection beam theory and the two-dimensional quasi-steady aerodynamic model are employed to model the aeroelastic blade, all the kinetic and inertial factors are taken into account in a unified manner. A five-nodes, 15-DOFs pre-twisted nonuniform beam element is developed for the discretization of the blade, three rigid-body-motion DOFs are introduced for the motion of the hinges and the bearing. The Hamilton's principle is employed to evaluate the equation of motion of the blade. The derived nonlinear ordinary differential equations with time-dependent periodic coefficients are solved by a modified quasi-linearization method, which is developed for the higher DOF periodic system. The resulting periodic forces and moments exerted on the fuselage by all the blades are evaluated every time, when the converged nonlinear periodic response of the blade is obtained under the consideration of the equilibrium of the blades. The fuselage structure is simplified to be a beam structure, the governing equation is established in the inertial reference frame and a two-nodes beam element is used to discretize the flexible fuselage. The periodic response of the fuselage is solved by a simple shooting method. The iteration of the rotor/fuselage response is continued, until the aeroelastic responses of the blade and the fuselage converge simultaneously. Both the hovering and the forward flight states can be considered. The results of a computed numerical example by the developed program are presented to verify in practice the economy of the modeling as well as the reliability and efficiency of the corresponding solving methods.

    Notes:
    Differential UV spectroscopy is employed to investigate the interaction of poly-U with Mg2+, Ca2+, Mn2+ and Cu2+ ions in aqueous solution. Mg2+ and Mn2+ ions are observed to bind only to the polynucleotide phosphates, while Cu2+ and Ca2+ also interact with the poly-U bases. The most probable coordination sites are O(4) and also N(3) for Cu2+ ions. N(3) is a coordination site of Cu2+ ions in UMP and uridine. The rest of the ions do not interact with the bases of the free monomers. Unlike the non-cooperative Cu2+-UMP binding, the ion interaction (including Ca2+) with the poly-U bases is characterized by a positive cooperativity. The association constant of Ca2+ (45 1.mol-1) is 45 times lower than that of Cu2+.
