    Notes: For bronze-processed multifilamentary pure Nb3Sn and 2.3 at. % Ti added (Nb,Ti)3Sn wires, which were prepared under the condition of the same wire parameters such as the filament size, filament number, and bronze ratio, the strain effects on the critical current density were measured. The large difference of the residual strain between Nb3Sn and (Nb,Ti)3Sn wires was obtained. It was found that the martensitic transformation for Nb3Sn compound largely contributes to the residual strain through the variation of the elastic modulus in bronze-processed multifilamentary Nb3Sn wires. It was verified that the ternary element addition of Ti surely suppresses the martensitic transformation in the bronze processed multifilamentary Nb3Sn wire.

    Electron cyclotron resonance heating by strong monochromatic wave in nonuniform magnetic field (1994)

    Notes: Numerical studies are made on dynamics of electrons under electron cyclotron resonance heating (ECRH) by a strong monochromatic wave in a nonuniform magnetic field. The response of the electrons is described in terms of gains in energy and magnetic moment. These expressions are employed to define a response function which connects the velocity distributions of electrons before and after heating in a wide range of conditions. The response function is applied to calculate the velocity distribution of cold electrons which stream up the magnetic slope and are heated at the resonance. This configuration simulates a possible scheme for controlling an inward flux of cold electrons in diverter regions of tori and in mirror ends by mirror reflection enhanced by ECRH. The velocity distribution shows wing-like structures which are not expected from diffusion equations.

    Theoretical analysis of thermal dike supported by electron cyclotron resonance heating (1994)

    Notes: Thermal dike is a new concept for controlling energy transport carried by electrons along open magnetic field lines by enhancing mirror-reflection with assistance of electron cyclotron resonance heating (ECRH). Quantitative analyses are made to evaluate merits of thermal dike and to clarify requirements for efficient use of it. Heating response function is applied for trajectory analyses of electrons streaming through the ECRH zone. Substantial power gain is obtained under a configuration with a high mirror ratio between the reflection point and the resonance point and with a large scale length of the magnetic gradient in the resonance zone. Thermal dike is shown to be beneficial both in tandem mirrors and in diverters in tori. Discussions are made also on a basic experiment program of thermal dike in the GAMMA 10 tandem mirror.

    Effect of fluoride on root resorption caused by mechanical injuries of the periodontal soft tissues in rats (1994)

    Notes: Abstract The present study was carried out to investigate histologically and histometrically the effect of fluoride on root resorption induced by mechanical injuries of the periodontal soft tissues in rats. Resorption lacuna in the root surface of the molar in animals given both mechanical injuries and fluoride administration was significantly smaller in length and area than that in animals given only mechanical injuries. Moreover, resorption lacuna in the former animals contained fewer odontoclasts than that in the latter. The results of the present study might suggest that the administration of fluoride suppressed root resorption induced by mechanical injuries of the periodontal soft tissues.

    High levels of erythrocyte aldose reductase and diabetic retinopathy in NIDDM patients (1994)

    Topics: Medicine
    Notes: Summary Erythrocyte aldose reductase was determined in 90 NIDDM patients by a two-site ELISA using recombinant human aldose reductase. The level of aldose reductase did not correlate with age, duration of diabetes, fasting blood glucose and HbA1c of the patients. Among 38 patients with diabetes for more than 10 years, aldose reductase in those with retinopathy (including non-proliferative and proliferative) was significantly higher than in those without, while no difference in the means of the average HbA1c, maximum and minimum blood pressure levels was observed between the two groups. The results indicate that the level of aldose reductase in the erythrocyte of diabetic patients is associated with the presence of retinopathy. [Diabetologia (1994) 37: 328–330]

    Lack of association of the insulin gene region with Type 1 (insulin-dependent) diabetes mellitus in Japanese subjects (1994)

    Notes: Summary Although the insulin gene region is implicated in susceptibility to Type 1 (insulin-dependent) diabetes mellitus in Caucasians, significance of this region to Type 1 diabetes in Japanese remains unclear because the class 1 alleles (shorter insertion) of the variable number of tandem repeat in the 5′ region of the insulin gene are predominant in both diabetic and non-diabetic subjects. The 5′ insulin gene polymorphism was analysed in 75 Japanese patients and 69 control subjects with a precise method using PvuII and a polymorphism specific probe, which enabled us to divide class 1 alleles into four subclasses. Allelic frequencies were not significantly different between Type 1 diabetic patients and control subjects. The polymorphism in the 3′ untranslated region of the insulin gene (1127/ PstI) was also analysed and found to be tightly linked to the 5′ insulin gene polymorphism, and thus was not associated with diabetes. Interaction between HLA-DR and the insulin gene region, which was reported in the French study, was not observed in Japanese. These results suggest that the insulin gene region is not a valuable genetic risk factor for Type 1 diabetes in Japanese. [Diabetologia (1994) 37: 210–213]

    Pigments of Rubrobacter radiotolerans (1994)

    Topics: Biology
    Notes: Abstract The highly radioresistant Rubrobacter radiotolerans, contains red pigments. Since the pigments could not be extracted by usual methods, a new method was developed in which the pigments were extracted with organic solvents after addition of 10 N KOH to the intact cells, followed by neutralization. These pigments were also extracted after treatment with achromopeptidase, but not with lysozyme. The extracted pigments separated into two main spots by TLC (48.6% and 22.6%), and were confirmed to be carotenoids by chemical tests. The two major pigments had 13 conjugated double bonds as determined from the main maximum wavelength of the light absorption spectra. Their molecular weights were determined to be 740 and 722 by mass spectrometry. The mass spectra of their TMS-derivatives revealed that they contained four and three tertiary OH groups, respectively. Confirming their identical light and IR spectra, these pigments were determined to be bacterioruberin and monoanhydrobacterioruberin, respectively, the characteristic carotenoids of halophilic bacteria. The existence of these pigments in bacteria other than halobacteria provides interesting new evidence on the distribution of these compounds.

    Non-destructive determination of low-level210Pb and226Ra with an ordinary high-purity Ge-detector (1994)

    Notes: Abstract A convenient non-destructive method for the determination of low level210Pb and226Ra with an ordinary high-purity Ge-detector is presented. The ordinary Ge-detectors used in this work were available to measure 46.5 keV γ-rays of210Pb. These detectors were also useful for the non-destructive analysis of low-level226Ra in lime-stone and calcium chemicals when a stream of nitrogen gas was maintained around the detectors. By this method, measurements could be carried out not only for210Pb and226Ra but also for other γ-emitting radionuclides simultaneously, using the same detector. The detection limits of about 1 Bq per sample for210Pb and about 0.05 Bq per sample for226Ra, respectively, were estimated, when the samples were counted for 1–2 days.
