[en] A heat-and momentum-transfer analysis is performed for the fully developed turbulent MHD flow of an electrically conducting fluid in a two-dimensional constant-area channel. It is assumed that a uniform magnetic field perpendicular to the insulated channel walls exists in the channel. A mathematical model of turbulence, which takes into account the suppression of turbulence by the magnetic field, is proposed for the prediction of the momentum transfer. The analytical results for skin-friction coefficients, mean velocity profiles, the distributions of eddy diffusivity, and of turbulent kinetic energy show good agreement with the relevant experimental data in the Reynolds number range from 50,000 to 200,000 and the Hartmann number range from 0 to 700. For the heat-transfer analysis, a case of constant wall heat flux is treated, and the tendency of the reduction of heat-transfer rate by the magnetic field shows good qualitative agreement with the experimental results

[en] Nephritogenic tubular epithelial antigen (Tub-Ag), which had been found in immune complexes deposited along the glomerular capillary walls of some patients with idiopathic membranous glomerulonephritis, was solubilized from renal tubuli of humans by Pronase digestion. Soluble Tub-Ag was then purified by gel filtration and ion exchange chromatography on DEAE-Sephadex. Three DEAE fractions, designated as 0.07 M, 0.13 M, and 0.23 M fractions, raised antibodies in rabbits, and fluoresceinated antibodies against any of these fractions reacted exclusively with luminal layer of proximal tubular epithelia. Among three fluoresceinated antibodies, however, only the one directed to 0.07 M fraction bound with immune complexes which were deposited along the glomerular capillary walls of the patients with Tub-Ag-mediated membranous glomerulonephritis. Purified Tub-Ag (DEAE 0.07 M fraction) was physicochemically homogenous with a S₂₀ value of 8.2. Utilizing ¹²⁵I-labeled Tub-Ag, a sensitive and quantitative radioimmunoassay of Tub-Ag was developed. Tub-Ag was demonstrated to occur naturally in serum and urine, as well as in all the organs tested including kidney, intestine, liver, spleen, stomach, heart, and lung

[en] To clarify whether photomechanical response is limited to the special combination of azobenzene (AzBz)/organophilic tetrasilicic mica (TSM) complexes, another swelling synthetic fluoro-mica, lithium taeniolite, was used as a starting host for AzBz/organophilic mica complexes. Basal spacings of organophilic taeniolites (o-TNs) prepared by the intercalation of trimethylalkylammonium (TMAA) into the TN increased linearly as alkyl chain length in TMAA increased from 2.44 to 2.86 nm. This indicates paraffin-type arrangement of TMAA in the TN gallery. Intercalation of AzBz to o-TN was performed via the gas phase at 100 deg. C. Photoresponses of AzBz/o-TN complexes were examined by XRD measurement under alternate UV and visible light irradiation. A decrease in basal spacing was observed under UV irradiation, and an increase was under visible light irradiation. Basal spacing change was 0.09-0.18 nm, which corresponds to 3-5% of the AzBz/o-TN basal spacing. These results indicate that reversible photomechanical response is a general phenomenon for AzBz/organophilic mica complexes

[en] It is intended that the toroidal field (TF) coils of the nuclear fusion machine utilize noncircular field coils in view of the mechanical strength of the coil. In these machines, TF coils are quite large, moreover experience considerably large electromagnetic force. Consequently, stress analysis plays an important role in the reliability of the coil. This paper describes the finite element stress analysis, field calculation of the D shape TF coil and the test results of the model coil. 4 refs

[en] Optical quality pure and Mn doped near stoichiometric lithium niobate (SLN) crystals were grown by top seeded solution growth using induction heating system. The growth parameters like temperature field, pulling and rotation rate have been optimized. Transmission studies revealed a shift in optical absorption towards longer wavelength for increased doping concentration. Curie temperature was found to decrease with Mn concentration. The effect of Mn doping on two-color sensitivity and dynamic range (M) on gating and writing intensities are also investigated. Long dark storage time has been obtained for the doped crystal

[en] The distribution of the boron-10 compound, Na2 10B12H11SH, which is now in clinical use for boron neutron capture therapy for brain tumors, was studied topographically and quantitatively in rats using neutron-induced alpha-autoradiography. Transplanted intracerebral tumors in Sprague-Dawley rats were used. In the normal brain, only a minute amount of 10B (less than 1 microgram 10B/cm3) was found in the brain parenchyma, except for the infundibulum and area postrema. Boron-10 accumulated in the brain tumors. The tumor-to-blood concentration ratio of 10B increased with time after injection and reached unity 12 hr after injection. The tumor concentration calculated at that time was 18 micrograms 10B/cm3. This study clearly shows that this 10B compound accumulates in the transplanted rat tumors in the brain and that tumor concentration and tumor-to-blood ratio of 10B can provide a sufficient condition for brain tumor treatment

[en] A structural design of the Large Helical Device (LHD) has been performed with proposals of: (1) application of forced flow superconductor to helical can poloidal coils, (2) toroidal shell for support structure of the coils and (3) corrugated vacuum vessel with high temperature difference between inner and outer skins. Structural analyses of these components have also been carried out to understand their mechanical behaviors including load transmission and to assess the structural reliabilities of the LHD.

[en] The Mitsubishi Group (MHI and MELCO) has completed the installation of the Integrated Digital I and C System to Tomari Unit 3 of HEPCO (Hokkaido Electric Power Co., Inc.), the newly-built PWR plant for the first time in 15 years in Japan. We have also applied the Integrated Digital I and C System to Ikata Unit 1/2 of SEPCO (Shikoku Electric Power Co., Inc.) during the renewal constructions of the Main Control Boards. The delivery for Unit 1/2 was completed in July and June of 2009, respectively. (author)

[en] An ideal therapy for brain tumors would be one whereby all tumor tissue is selectively destroyed without causing damage to the functioning brain. For the boron neutron capture treatment to be ideal, it must meet the minimum requirement that boron-10 be distributed within a tumor and only in the tumor. Boron-10 distribution in non-transplanted brain tumors had not yet been studied. The difference between transplanted tumor and non-transplanted tumor is quite significant with respect to the difference in susceptibility to boron penetration. The authors report on boron-10 distribution in primary brain tumors of rats induced by ethylnitrosourea (ENU) as well as in transplanted rat brain tumors, and discuss the mechanism of the boron-10 accumulation in the tumor

[en] Monoclonal antibodies to varicella zoster virus (VZV) glycoproteins were used to study the processing of three glycoproteins with molecular weights of 83K-94K (gp 2), 64K (gp 3), and 55K (gp 5). Immunoprecipitation experiments performed with VZV-infected cells, pulse labeled with [³H]glucosamine in the presence of tunicamycin, suggest that O-linked oligosaccharide is present on the glycoprotein of gp 2. Use of the enzyme endo-beta-N-acetylglucosaminidase H revealed that the fully processed form of gp 3 had high-mannose type and that of gp 5 had only complex type of N-linked oligosaccharides. Experiments with monensin suggest that the precursor form (116K) of gp 3 is cleaved during the processing from Golgi apparatus to cell surface membrane. The extension of O-linked oligosaccharide chain and the complex type of N-linked oligosaccharide chains also occurs during this processing
