    Notes: Melt-regrowth properties of 60-nm-thick silicon films were characterized in the case of electrical-current-induced joule heating. The electrical energy accumulated at a capacitance caused melting of the silicon films via joule heating with a maximum intensity at 1.5×106 W/cm2. The melt-regrowth duration increased from 6 to 75 μs as the capacitance increased to 0.05–1.5 μF. Crystalline properties of the silicon films were also investigated. 7 μm long crystalline grains with the (110) preferential crystalline orientation were observed using a transmission electron microscope. The tensile stress at 3.4×108 Pa remained in the films. The analysis of electrical conductivity resulted in a density of defect states of 3.5×1016 cm−3 in the films. The product of the generation efficiency, the carrier mobility and the average carrier lifetime was estimated to be ∼10−3 cm2/V. © 2001 American Institute of Physics.

    Notes: Thick-film technology has been successfully adapted for the design and fabrication of magnetic probes of a new type suitable for use in the simultaneous ultrahigh vacuum and high temperature environment of a nuclear fusion device. The maximum usable temperature is expected to be around 900 °C. This new probe has a specific sensitivity (coupling area per unit volume) an order of magnitude higher than a conventional coil. The new probe in one implementation is capable of simultaneously measuring magnetic field in three orthogonal directions about a single spatial point and in two frequency ranges. Low frequency coils have a measured coupling area of 296–323 cm2, and a frequency response of about 300 kHz. High frequency coils have a design coupling area of 12–15 cm2. © 2001 American Institute of Physics.

    Photoperiodic regulation of CS-ACS2, CS-ACS4 and CS-ERS gene expression contributes to the femaleness of cucumber flowers through diurnal ethylene production under short-day conditions (2003)

    Notes: Photoperiod and the plant hormone, ethylene, modify sex expression of flowers in cucumber (Cucumis sativus L.). In the present study, femaleness of cucumber occurred under short-day (8 h photoperiod) conditions compared to that under long-day (16 h photoperiod) conditions, although the effect of photoperiod was more pronounced in a monoecious than in an andromonoecious cucumber. Application of ethylene had a greater effect than photoperiod on the production of female and bisexual flowers in monoecious and andromonoecious cucumbers, respectively. Ethylene evolution and the expression of CS-ACS2, CS-ACS4 and CS-ERS genes in the shoot apices of both monoecious and andromonoecious cucumber plants had a diurnal rhythm with a peak in the middle of an 8 h or a 16 h light period. Peak ethylene evolution and expression of CS-ACS2 was greater under short-day conditions than under long-day conditions in a monoecious cucumber but not in an andromonoecious one. Expression of CS-ACS4 in monoecious and andromonoecious cucumber plants did not differ, but the level was higher under short-day conditions compared with that under long-day conditions. Thus, CS-ACS2 and CS-ACS4 might be involved in the basic diurnal rhythm of ethylene evolution in cucumber. Because exogenous ethylene increased the expression of CS-ACS2 and CS-ERS in monoecious cucumber possessing the M locus, but not in andromonoecious cucumber in which the function of the M locus was lost (Yamasaki et al. Plant and Cell Physiology 42, 608–619, 2001), the CS-ACS2 gene might also be involved in ethylene production by positive feedback via regulation of M locus under short-day conditions.

    A variety of wheat tolerant to deep-seeding conditions: elongation of the first internode depends on the response to gibberellin and potassium (2001)

    Notes: The addition of gibberellin A3 (GA3) to culture media induced a dramatic elongation of the first internode in Hong Mang Mai, a wheat variety tolerant to deep-seeding conditions. The length of the first internode in the GA3-treated seedlings reached approximately 45 cm, which is twice as long as that of the control, whereas first internodes of other varieties were 3 to 12 cm long and hardly affected by GA3. The level of endogenous gibberellins (GA) in Hong Mang Mai was not greater than that of other wheat varieties. The expression of GAMyb, a transcription factor, was abundant in the first internode and substantially increased by GA3 application in Hong Mang Mai, compared with other wheat varieties. These results suggest that the first internode of Hong Mang Mai is more sensitive to GA in inducing strong elongation. The presence of potassium in the culture media was indispensable for the first internode elongation. Application of GA3 enhanced the uptake of potassium in Hong Mang Mai. Higher sensitivity of the first internode to GA could cause strong elongation by increasing the amount of osmotic solute, which plays an important role in the tolerance mechanism of Hong Mang Mai to deep-seeding conditions.

    The effect of gravity on surface temperatures of plant leaves (2003)

    Topics: Biology
    Notes: A fundamental study was conducted to develop a facility having an adequate air circulation system for growing healthy plants over a long-term under microgravity conditions in space. To clarify the effects of gravity on heat exchange between plant leaves and the ambient air, surface temperatures of sweet potato and barley leaves and replica leaves made of wet paper and copper were evaluated at gravity levels of 0.01, 1.0, 1.5 and 2.0 g for 20 s each during parabolic aeroplane flights. Thermal images were captured using infrared thermography at an air temperature of 26 °C, a relative humidity of 18% and an irradiance of 260 W  m−2. Mean leaf temperatures increased by 0.9–1.0 °C with decreasing gravity levels from 1.0 to 0.01 g and decreased by 0.5 °C with increasing gravity levels from 1.0 to 2.0 g. The increase in leaf temperatures was at most 1.9 °C for sweet potato leaves over 20 s as gravity decreased from 1.0 to 0.01 g. The boundary layer conductance to sensible heat exchange decreased by 5% when the gravity decreased from 1.0 to 0.01 g at the air velocity of 0.2 m s−1. The decrease in the boundary layer conductance with decrease in the gravity levels was more significant in a lower air velocity. Heat exchange between leaves and the ambient air was more retarded at lower gravity levels because of less sensible and latent heat transfers with less heat convection.

    Evidence for type assortative mating between the freshwater and Omono types of nine-spined stickleback in natural fresh water (2002)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 61 (2002), S. 0

    Topics: Biology
    Notes: A total of 123 adult specimens of the nine-spined stickleback Pungitius pungitius were identified as either the freshwater or Omono types, based on diagnostic allozyme loci, and their allozyme patterns compared with restriction fragment length polymorphism patterns of polymerase chain reaction-amplified mtDNA segments (mtDNA PCR-RFLP pattern). All specimens of the two types were clearly identified by the mtDNA PCR-RFLP patterns, except for a single putative hybrid progeny. The mtDNA PCR-RFLP patterns of 133 clutches from 21 nests were also compared with those of their parental males, and 126 out of 127 clutches were found to be consistent with the parental male pattern, the remaining six clutches being guarded by an F1 hybrid male. The results demonstrated that type assortative mating had occurred between the two types in nature, indicating the existence of a premating isolating mechanism between them.

    Notes: Abstract. The present paper introduces a majority orienting model in which the dealers’ behavior changes based on the influence of the price to show the oscillation of stock price in the stock market. We show the oscillation of the price for the model by applying the van der Pol equation which is a deterministic approximation of our model.

    Notes: The effects of helium and aging treatment on radiation damage behavior in low activation Fe-Cr-Mn ( W, V) alloy were investigated by electron and helium ion dual-beam irradiation in a high voltage electron microscope. Specimens were aged at 673 K, 823 K and 923 K for 1000, 3000 and 10000 hours. Electron and He ion dual-beam irradiations were performed at 627 K to 10 dpa. M23C6 type carbides were precipitated in the aged specimens, and the amount of the precipitates was increased with increasing aging temperature and aging time. He bubbles were formed during dual-beam irradiation in all of the specimens. The cavity swelling under dual-beam irradiations was increased with increasing the aging temperature and aging time. It was suggested that cavity swelling is closely related to the concentration of solutes such as Cr and C in the matrix, namely cavity growth rate becomes higher with decreasing of the solutes in solution
