    Notes: In a hydrogen-doped metallic glass, there appear low-temperature and high-temperatureinternal friction peaks respectively associated with a point-defect relaxation and the crystallization.The high-temperature-side slope of low-temperature peak and also the low-temperature-side slopeof high-temperature peak enhance the background internal friction near the room temperature. Ahydrogen-doped Mg-base metallic glass was proposed as a high-damping material to be used nearand somewhat above the room temperature. Stability of the high damping was also checked

    Internal Friction of Hydrogenated Ti (Ni,Cu) Shape Memory Alloys (2006)

    Notes: Effects of hydrogen doping on the internal friction (IF) of ternary Ti50Ni50-xCux (x=15, 20,25)[removed info] shape memory alloys, prepared by rolling and annealing laminating Ti and Ni-Cu alloy sheets,have been measured with a damping mechanical analyzer in a forced bending oscillation mode attemperatures from 173K to 423K at three frequencies, 0.1, 1 and 5Hz. The effects of hydrogendoping on IF are common to the three alloys: a hydrogen IF peak appears at around 260K; the IFpeak value (tanφ) increases rapidly with increasing hydrogen concentration up to tanφ=0.03 at0.5at% and then decreases; the peak temperature also increases rapidly and then gradually decreases.From the frequency dependence of the peak temperature, the activation energy E and thepre-exponential factor ω0 have been analyzed to be E=0.6-0.7eV and ω0=1013-14s-1. The origin of thehydrogen IF is interpreted to be the Snoek-Koester effect due to interaction of twin boundarydislocations and segregated hydrogen atoms. Effects of hydrogen on mechanical properties of thealloys have also been studied

    New severe strains of Melon necrotic spot virus: symptomatology and sequencing (2005)
    Oxford, UK : Blackwell Science Ltd
    Plant pathology 54 (2005), S. 0 
    Details

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: New strains of Melon necrotic spot virus (MNSV), designated MNSV-YS and MNSV-KS, caused much more severe growth retardation on melon plants than MNSV-NH, which was previously reported as the most severe strain of MNSV in Japan. MNSV-YS spread much more quickly than MNSV-NH in infected plants, and induced more severe growth retardation, even though the appearance of necrotic lesions on inoculated cotyledons was much slower. MNSV-KS had properties intermediate between those of the other two strains. The results suggest that faster-spreading strains can multiply more rapidly as a result of lower levels of activity in inducing necrotic lesions in melon plants. The complete sequences of MNSV-YS and MNSV-KS were determined, and an RT–PCR–RFLP method based on these sequences was successfully developed to detect and discriminate between the three strains.

    Diagnostic and Follow-up Studies on CEA, AFP and ALP4 Isoenzyme in the Sera of Gynecological Malignancies (1978)
    Oxford, UK : Blackwell Publishing Ltd
    Scandinavian journal of immunology 8 (1978), S. 0 
    Details
    ISSN: 1365-3083
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: Simultaneous determination of CEA, AFP and ALP4 was made in patients with various gynecological malignancies. CEA was positive in 65%, AFP was positive in 1.8% of 55 cases with cervical carcinoma stage 0—-II. ALP4 was positive in one patient in these stages. In the group of cervical carcinoma stage III, stage IV and recurrence, CEA and AFP were positive in 100% and in 8.6% of 35 cases respectively. ALP4 was positive in 14.3%. High levels and/or progressively increasing CEA with positive ALP4 were found to be significant in poor prognostic patients in whom ALP4 was not always found positive. Out of 17 cases with endometrial carcinoma, CEA was positive in 12 patients. AFP and ALP4 were each positive in one case. Of 30 cases with ovarian carcinoma, CEA was positive in 70%, AFP in 23% and ALP4 in 14%. Increasing CEA and/or increasing AFP appeared to be correlated with poor prognosis. In the group of 5 vulvar carcinoma, only CEA was positive in 80% of the patients. Of 19 cases of choriocarcinoma, CEA was positive in 11%, AFP was positive in 5.3% and ALP4 was positive in 5.6%. There existed reverse-correlation between serum CEA and AFP in some cases.

    Steady-state creep of single-phase crystalline matter at high temperature (1976)
    Springer
    Journal of materials science 11 (1976), S. 1542-1566 
    Details

    Notes: Abstract Over the past 15 years important advances have been made in the experimental study of the microstructural changes occurring during the non-linear steady-state creep of single phase crystalline matter at elevated temperatures. Curiously, although the results of these painstaking studies have gone a long way toward elucidating the mechanism of this phenomenon, they have been largely ignored in favour of some simple dislocation mechanisms that are not only inconsistent with these observations, but are also unable to describe correctly the known phenomenology. This review concentrates primarily on the recent experiments on microstructural alterations occurring during creep; however, it also surveys the many mechanistic models that attempt to describe this phenomenon, and finds them all deficient.
