    Notes: Bopindolol, a non-selective antagonist of β1- and β2-adrenoceptors (ARs), has been found by pharmacological, molecular biological techniques and molecular modeling to have several unique properties. Bopindolol produces sustained blockade of β1- and β2-ARs, has intrinsic sympathomimetic as well as membrane stabilizing actions, inhibits renin secretion, and interacts with 5-HT receptors. Also, our recent molecular modeling studies identified possible interaction sites between bopindolol and beta-AR subtypes. The reviewed studies support our findings that bopindolol is non-selective for β1- and β2-ARs, has low affinity for β3-AR subtype and has pharmacological properties that are likely to be beneficial in the treatment of cardiovascular diseases.

    Notes: Using small-angle neutron scattering (SANS), we examined the magnetic microstructure of Co-12 at. % Cr-2 at. % Ta films sputter-deposited at 200 °C. Nuclear magnetic resonance confirmed the presence of highly Co-enriched regions produced by compositional separation. The SANS spectrum exhibited a main magnetic scattering peak corresponding to a size of several nm in the magnetic microstructure. This is indicative of a fine and uniform distribution of Co-enriched regions suitable for high-density magnetic recording. © 1996 American Institute of Physics.

    Selective nucleation and growth of diamond particles by plasma-assisted chemical vapor deposition (1989)

    Notes: Diamond particles have been selectively synthesized on a SiO2 dot-patterned Si substrate using plasma-assisted chemical vapor deposition (plasma CVD). Nucleation densities on both Si and SiO2 have been increased, first by pretreatment using abrasive powders; then, to eliminate the pretreatment effect from almost all of the substrate and to retain the effect only at designed sites, an Ar beam is used to obliquely irradiate the pretreated substrate. After deposition using plasma CVD, diamond particles have selectively formed on one edge of the SiO2 dots according to the pattern and have grown large to adjoin with adjacent particles. Polycrystals with equal grain sizes have been synthesized.

    Numerical study on laminar flow forced-convection heat transfer for air in a channel with offset plates heated by radiation heat flux (1998)

    Notes: A two-dimensional numerical study was carried out to investigate laminar forced-convection heat transfer characteristics of air flow in a two parallel plate channel with offset plates and heated by a radiation heat flux. The SIMPLE method was used for the numerical prediction of the flow and thermal fields. The flow field temperature boundary conditions were obtained by applying the energy balance equation to boundary elements. The ray tracing technique was used to obtain the net absorbed radiation fractions in the boundary elements. The numerical results were validated with measured temperature values and experimentally calculated values of local Nusselt number (Nux), and a reasonable agreement was shown. Then the numerical simulation was used to study effects of design parameters on the convective heat transfer coefficient. It was found that in Re numbers from 650 to 2,550, the optimum spacing of offset plates relative to the nearest channel wall was around one third of the channel height. Also, the optimum offset plates' numbers can be calculated based on one offset plate length being equal to one and a half times the channel hydraulic diameter. A correlation of average Nusselt number between the flowing air and the offset plates was obtained as follows; —Nu = 1.81 Re 0.352Pr1/3(Dh/l)1/2.

    A fundamental study of combined free and forced convective heat transfer from a vertical plate followed by a backward step (1998)

    Notes: Combined forced and free laminar convective heat transfer on a vertical plate with a backward-facing step has been studied numerically and experimentally, considering the effects of the interaction between the buoyancy and inertia forces which play a significant role in this phenomenon with the step-geometry factor of d/L. The convective heat transfer behavior in connection with the reattachment and recirculation flows appearing in the step region has been investigated based on the numerical calculations and Mach-Zehnder interferometer measurement under the wide range of the thermal condition. The behaviors of local Nusselt number NuL, velocity and temperature boundary layers and streamline fields in the recirculating region have been discussed for the various parameters of Grashof number GrL, Reynolds number ReL and the geometry factor d/L. The characteristic behavior of this convection heat transfer, including the vortex flow mode in the recirculating region and the unstable fluctuating mode near the reattaching point appearing at the specific condition, has been clarified numerically and experimentally by introducing the generalized coupling parameter GrL/ReL2 and geometry factor d/L.

    Neighborhood effects and genetic structure in a clonal grass: The role of the spatial structure of the environment (2001)

    Notes: A dominant plant of temperate nutrient-poor grasslands, Festuca rubra, has been used as a model species to assess biotic effects of fine-scale environmental heterogeneity in the field and its genetic differentiation in response to this variation. Using experimental data, it is shown that this heterogeneity is partly due to interspecific variation in competitive abilities in the ‘matrix’ plants. Festuca rubra possesses remarkable intraspecific differentiation in its parameters of spatial spreading and competitive performance, and in their plasticity under cultured conditions. This morphological plastic response to the environment is weaker in the field. This indicates that in the field individuals use only a fraction of the full potential range of plasticity to respond to variation in competitive environments. A random amplified polymorphic DNA study has shown that populations of F. rubra consist of a high number of coexisting genets. The genet size distribution is strongly skewed, indicating high early stage mortality and lower larger genet mortality. There should be continuous seedling regeneration in order to maintain this genetic structure. The data presented here display major features that distinguish clonal expansion from vertical competition. These are: (i) absence of integration over the whole plant; (ii) potentially unlimited size; (iii) large and unpredictable environmental variation experienced by different parts of the genet; and (iv) absence of a size-determined competition outcome at the genet level, and thus higher potential for species-specific effects.

    On the ecological and evolutionary significance of storage in clonal plants (1999)

    Notes: Environmental heterogeneity has received wide attention in clonal plant research over the last decade. Most studies have focussed on the effects of spatial variation in environmental conditions on the performance of ramets and genets, while the effects of temporal heterogeneity have only occasionally been studied. As a consequence, our current knowledge about functional responses of clonal plants to habitat patchiness is biased towards spatial aspects of environmental heterogeneity. Nevertheless, temporal changes in biotic and abiotic conditions do occur in most natural habitats, and they are very likely to affect plant growth and performance, and to create positive selection pressures on traits that can buffer plants against unfavorable consequences of this variability. Storage of resources is a widespread phenomenon in clonal plant species. Typical clonal structures such as stolons, rhizomes and hibernacles serve as storage organs. However, the ecologic significance of storage in clonal plant structures remains partly unclear. We suggest that the lack of understanding with respect to resource storage in clonal plants be related to our poor knowledge of ecologic implications of temporal habitat heterogeneity in natural environments. Resource storage can be understood as a safety measure against temporal changes in the growing conditions of plants. This paper summarizes existing information about the ecologic relevance of storage in clonal plants and it tries to develop a framework for further investigation of resource storage as a strategy to enhance the performance of clonal plants in temporally variable environments.
