    Observation of soft x-ray emission in the corona of 0.35-μm laser-irradiated gold disks (1991)

    Notes: The Phebus laser was used to irradiate gold targets at λ=0.35 μm; the laser pulse was 0.7 or 1.3 ns and the energy on target 1 to 1.8 kJ. The incident intensity was varied from 3×1013 to 3×1015 W/cm2. The time history of x-ray emission was monitored in the range 0.2–2.5 keV with a streak camera coupled with a transmission grating. Numerical simulations cannot replicate the temporal evolution of soft x-ray emission (hν〈800 eV), although the total conversion efficiency is correctly reproduced. Some observations, including time and space-resolved images, show that unexpected soft x-ray emission is produced in the corona at large distances from the target surface. A possible explanation is that cold and dense jets are generated towards the underdense plasma by an instability.

    Notes: We report the first operation of a direct diode-pumped tunable chromium-doped solid-state laser. A small alexandrite (Cr:BeAl2O4) crystal was longitudinally pumped by two visible laser diodes. The threshold pump power was 12 mW using the R1 line at 680.4 nm for the pump transition, and the slope efficiency was 25%. The measured laser output bandwidth was 2.1 nm.

    Flextensional Barium Strontium Titanate Actuators (2003)

    Notes: This paper describes the performance of the cymbal flextensional transducer using Dy-doped barium strontium titanate (BST) as the driver material. BST was first characterized for its dielectric and loss behavior as a function of temperature and electrical bias field. With no electrical bias, the transition temperature was measured to be near 20°C and have a dielectric constant 〉20 000. The strain of a BST disk was then measured and compared with other ceramics. At room temperature the strain and average effective piezoelectric d33 of this non-lead composition was slightly larger than Navy type I lead zirconate titanate (PZT-4) ceramic. The strain/field behavior was also measured as a function of temperature. Cymbal capped BST ceramic was found to have an amplified displacement of 28×, also very similar to type I ceramic. The stiffness of BST was found to be tunable by dc voltage and 2 to 3 times larger than that of PZT. This material has promise for applications in actuators and transducers with large generative force.

    SPURIOUS INJURY AS INDIRECT RENT SEEKING: FREE TRADE UNDER THE PROSPECT OF PROTECTION (1991)
    Oxford, UK : Blackwell Publishing Ltd
    Economics & politics 3 (1991), S. 0 
    Details

    Notes: In the literature on directly unproductive profit seeking or rent seeking, intervention-seeking by labor and industry groups is generally restricted to direct lobbying activity. However, import-competing producers may have an additional instrument to influence the decision to grant protection. Under well-established injury criteria for protection import-competing producers have an incentive, either collectively or individually, to feign injury. To the extent that the free-rider problem can be overcome, orchestrating the appearance of injury is an intervention-seeking activity that may be complementary to DUP lobbying. When the established indicators of industry well-being include variables controlled by the prospective beneficiaries, therefore, free trade under the prospect of protection is potentially accompanied by a concomitant spurious-injury distortion. Some of the positive and welfare implications of the theory of spurious injury are investigated in both a partial equilibrium framework and in the Heckscher-Ohlin model.

    Genetic characterization of spontaneous diploid androgenetic wheat and triticale plants (2002)

    Notes: The homozygosity of spontaneous hexaploid plants derived from anther culture was evaluated in wheat and triticale by means of 18 and 22 microsatellite markers, respectively. Most of the spontaneous hexaploid plants were homozygous for all the loci tested and had chromosomes recombining for parental alleles. Only 12% of the spontaneous hexaploid wheat plants, 11% of the artificially doubled wheat plants and 4.4% of the spontaneous hexaploid triticale plants were heterozygous at one to three of the loci studied. This showed that spontaneous hexaploid plants mostly came from normal haploid cells, obtained after meiosis, that underwent spontaneous chromosome doubling. However, first or second division restitution, producing unreduced gametes, cannot be completely excluded to explain the origin of the spontaneous hexaploid plants. Cytomixis, involving only one chromosome, or development of aneuploid trisomic gametes, followed by chromosome doubling for the spontaneous hexaploid plants, or transposition events could also explain some of the results obtained.

    Molecular and physical mapping of genes affecting awning in wheat (2002)

    Notes: Quantitative trait loci (QTL) for three traits related to awning (awn length at the base, the middle and the top of the ear) in wheat were mapped in a doubled-haploid line (DH) population derived from the cross between the cultivars ‘Courtot’ (awned) and ‘Chinese Spring’ (awnless) and grown in Clermont-Ferrand, France, under natural field conditions. A molecular marker linkage map of this cross that was previously constructed based on 187 DH lines and 550 markers was used for the QTL mapping. The genome was well covered (more than 95%) and a set of anchor loci regularly spaced (one marker every 20.8 cM) was chosen for marker regression analysis. For each trait, only two consistent QTL were identified with individual effects ranging from 8.5 to 45.9% of the total phenotypic variation. These two QTL cosegregated with the genes Hd on chromosome 4A and B2 on chromosome 6B, which are known to inhibit awning. The results were confirmed using ‘Chinese Spring’ deletion lines of these two chromosomes, which have awned spikes, while ‘Chinese Spring’ is usually awnless. No quantitative trait locus was detected on chromosome 5A where the B1 awn-inhibitor gene is located, suggesting that both ‘Courtot’ and ‘Chinese Spring’ have the same allelic constitution at this locus. The occurrence of awned speltoid spikes on the deletion lines of this chromosome suggests that ‘Chinese Spring’ and ‘Courtot’ have the dominant B1 allele, indicating that B1 alone has insufficient effect to induce complete awn inhibition.
