    Notes: A closed hydrodynamic approach for a full nonparabolic band model is developed from the maximum entropy principle. Generalized kinetic fields are introduced within a total average-energy scheme. Numerical calculations for bulk and submicron Si structures are found to compare well with those obtained by ensemble Monte Carlo simulators thus validating the proposed approach. © 1999 American Institute of Physics.

    Notes: A hydrodynamic (HD) transport approach based on a closed system of balance equations is developed from the maximum entropy principle. By considering a nonlinear expansion with respect to a local thermodynamic equilibrium, we determine an analytic expression for the distribution function as a function of macroscopic quantities such as density, velocity, energy, deviatoric stress, heat flux associated with charge carriers. From the determined distribution function and considering the collision interactions of carriers with phonons, all the constitutive functions appearing in the fluxes and collisional productions of the balance equations are explicitly calculated. The analytical closure so obtained is applied to the case of some n+nn+ submicron Si structures. Numerical HD calculations are found to compare well with those obtained by an ensemble Monte Carlo simulator thus validating the approach developed here. © 1999 American Institute of Physics.

    Field equations for charge conducting fluids in electromagnetic fields (1995)

    Notes: Abstract. Previous relativistic theories of thermodynamics of fluid mixtures can be extended to include more independent variables. Here the particular case is considered of a 3-constituent mixture consisting of a non-conducting fluid and two charged fluids; extension to the general case is straightforward. A set of field equations is found for the determination of the fields, following the methods of extended thermodynamics. These equations are restricted by the entropy principle and by material objectivity, obtaining in this way a closed hyperbolic system of field equations. As a byproduct of these principles, interesting stringent inequalities are obtained for the relaxation times arising from the production terms.

    TherolD gene fromAgrobacterium rhizogenes is developmentally regulated in transgenic tobacco (1997)

    Notes: Summary TherolD gene fromAgrobacterium rhizogenes has recently been shown to induce striking precocity of flowering in transgenic tobacco. A transcriptional fusion between 578 bp of therolD upstream regulating sequence and the GUS reporter gene has been transferred to tobacco plants and its expression analysed throughout the whole life cycle of the plant. A detailed histological analysis revealed thatrolD is strongly expressed in elongating and differentiating tissues of each organ, from the mature embryo to the adult plant. In organs with determinate growth, such as cotyledons, leaves and floral parts,rolD expression follows the age gradient of the tissues. In mature tissues,rolD expression is high, begins to decrease with ageing and is switched off when senescence occurs.RolD is also active in the vascular system, in the procambium, pith- and receptacular-meristems. Our data show that expression ofrolD is under developmental control as it correlates with, and may represent a molecular marker for, the elongation/expansion and maturation phases of the plant tissues.

    Bacterial plant oncogenes: Therol genes' saga (1994)
    Springer

    ISSN: 1573-6857

    Topics: Biology
    Notes: Abstract Therol genes are part of the T-DNA which is transferred byAgrobacterium rhizogenes in plant cells, causing neoplastic growth and differentiation. Each of these bacterial oncogenes deeply influences plant development and is finely regulated once transferred into the plant host. Both from the study of the effects and biochemical function of therol genes and from the analysis of their regulation, important insight in plant development can be derived. Some of the most intriguing aspects of past, current and future research on this gene system are highlighted and discussed.
