    Notes: The effects of Li+ addition on the sintering and microstructural evolution of cordierite wereanalyzed. As nucleating agent, the Li+ additive decreased the expansion coefficient and dielectricconstant. The doping of Li+ was found to block the phase transition from μ-cordierite to α-cordierite andincrease sintering temperatures. The effect of Li+ on the activation of cordierite can be attributed to thenucleation of cordierite. Too much Li+ will inhibit the cordierite crystallization and encourageamblygonite crystallization. Cordierite powders were prepared by sol-gel processing

    Broodstock Rearing and Controlled Reproduction of Reeves Shad Tenualosa reevesii (2003)

    Notes: Reeves shad Tenualosa reevesii is one of China's best known anadromous fish, but is presently on the verge of extinction. There is an urgent need for conservation of this species through artificial reproduction and culture. In this study, shad broodstock were held in captivity then were induced to spawn with serial injections of luteinizing hormone-releasing hormone analogue (LHRHa) following GtH priming by implantations of 17-methytestosterone (T) combined with environmental manipulations. Induced maturation of 4, 5, and 6-year-old females reached 83.3%, 87.5%, and 100%, respectively, while fish in control treatments remained immature. During the gonadal development priming period, mean serum 17-estradiol levels in the T treatment were significantly higher than the LHRHa treatment and control fish. Gonadal development of females was suppressed when their mesenteric fat index was below 1.5% by April. The effective accumulating temperatures for female and male maturation were 3,995 ± 31.4 C/d and 2,278 ± 8.9 C/d, respectively. Two injections of LHRHa in combination with domperidone (DOM) and environmental regulations were effective in inducing ovulation. About 800,000 fertilized ova were obtained (fertilization 75%) in 1995, and 5,000 fry were hatched in 1996. These results are an important step to develop shad culture and save this endangered species.

    Prey-size Preference, Maximum Handling Size, and Consumption Rates for Redear Sunfish Lepomis microlophus Feeding on Two Gastropods Common to Aquaculture Ponds (2003)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Maximum handling sizes, prey size and species preferences, and ad libitum consumption rates were determined for three size classes of redear sunfish Lepomis microlophus feeding on Physa gyrina and Helisoma trivolvis, two common aquaculture-pond snails which serve as intermediate hosts for fish parasites. Maximum handling-size experiments indicated that redear sunfish as small as 14-cm total length were capable of consuming all sizes of Physa typically observed in ponds, whereas only redear sunfish of at least 32-cm total length are capable of consuming all commonly observed sizes of pond-dwelling Helisoma. When presented with a range of sizes of both snail species, redear sunfish consumed higher proportions of smaller- and medium-sized snails; the largest snails offered were uneaten or consumed in relatively small quantities. Multiple linear regression was applied to consumption data to develop a simple model for predicting mean daily ad libitum consumption rate (g/g per d) for redear sunfish feeding on snails with temperature (20–27 C) and fish total length (9–24 cm) as independent variables. Our findings will facilitate prediction of numbers of redear sunfish of a given size required to control populations of Physa and Helisoma in ponds. Such predictions will enable pond owners to quickly evaluate whether stocking redear sunfish as a control agent for undesirable snail populations will be economically and logistically feasible. Findings also indicate potential limitations in the use of redear sunfish to control populations of Helisoma due to the inability of redear sunfish as large as 24-cm total length to consume the largest 30–40% of Helisoma commonly observed in ponds and to the expense of stocking larger fish (32-cm total length) capable of consuming all sizes of Helisoma.

    Dynamics of magnetic domain walls in an oscillating field (2000)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 87 (2000), S. 6499-6501

    ISSN: 1089-7550

    Notes: The dynamics of domain walls in an ac magnetic field is formulated and solved numerically under free boundary conditions. Previous calculations are applicable only in the limit when the sample size is much less than the bare penetration depth, whereas no such approximation is made in the present approach. Our calculation provides for an interpretation of recent experimental results that observe a peak in the ac susceptibility of soft magnets as a function of the amplitude of the external magnetic field. © 2000 American Institute of Physics.

The effect of Bi3+ on the activation of cordierite can be attributed to the nucleation of cordierite. The doping of Bi3+ increased the expansion coefficient and dielectric constant. Too much Bi3+ will inhibit the cordierite crystallization and encourage anorthite crystallization

    Notes: The cordierite powders have been synthesized by low temperature combustion technique usingurea as fuel, nitrates as oxidizer and silicic acid as silica source. The sintering behavior and crystallizationprocess were investigated. The results showed that the powders could be sintered at a temperature lowerthan 1000 ºC. The μ-cordierite crystallized from glass at first, and then transformed into α-cordierite athigher temperature. The obtained cordierite based glass ceramics at different temperatures have lowdielectric constant (4.16 ~ 5.02 at 1 MHz) and low dielectric dissipation factor (≈ 0.003 at 1 MHz) as wellas low temperature sintering behavior, which is compatible for electronic packaging

    Notes: Al2O3 coatings were fabricated by multi-functional micro-plasma spray through axialpowder feed. The flight particle velocity and temperature were measured by SprayWatch-2i. With therising of Ar flow, the velocity of Al2O3 particles increases, but the temperature of particles decreasesgradually. Al2O3 coatings were analyzed by SEM and XRD. The microstructure of coatings is density,low porosity and uniform morphology. X-ray diffraction results show that α-Al2O3 is the main phasein the original Al2O3 powders, but Al2O3 coatings consist of γ-Al2O3 and a small amount of α-Al2O3.The microhardness and bonding strength of Al2O3 coatings were also measured, which isHV0.11183~1387 and 28.6MPa, respectively
