[en] Effects of substrate laser glass on the damage threshold and adhesion of dielectric films has been studied in order to improve the damage threshold. The study is divided into two parts: the first part dealing with four types of laser glass, LSG-91H silicate, LHG-8 phosphate, P-1 phosphate and LHG-10 fluorophosphate; the second part dealing with twenty-six glasses with systematically modified compositions in three glass systems, silicate, phosphate and fluorophosphate

[en] We report a search for muon neutrino disappearance in the Δm² region of 0.5--40 eV² using data from both Sci-BooNE and MiniBooNE experiments. SciBooNE data provides a constraint on the neutrino flux, so that the sensitivity to ν_μ disappearance with both detectors is better than with just MiniBooNE alone. The preliminary sensitivity for a joint ν_μ disappearance search is presented.

[en] Evaluation on activation cross section data for the JENDL activation file was started two years ago. Since there are already big activation libraries in western Europe and in the United States, we are aiming at more accurate evaluation of important reactions to applications to fission and fusion reactors rather than aiming at as many reactions as in these big libraries. About 1,000 reaction cross sections have been evaluated for 37 most important elements up to 20 MeV. In this fiscal year we are going to evaluate about 1,000 reactions of 22 elements designated as the second priority. The JENDL activation file will be finalized by March 1991

[en] Two-year-old potted 'Tosa Buntan' pomelo (Citrus grandis (L.) Osbeck) trees on trifoliate orange (Poncirus trifoliata Raf.) rootstock grown in a plastic house were used in this study. The temperature of the plastic house was maintained at a maximum of 20°C during the day and 10°C minimum at night from November 1990 to mid-February 1991. On December 1990, a set of potted trees was transferred to each growth chamber which was kept at day/night temperature of 15°/5°C and 10°/10°C. A subgroup of these trees was exposed to these condition for 15, 30, 45, 60, and 75 days and then transferred to another growth chamber maintained at 30°/25°C (day/night). On 1 December 1990, 15 January, and 15 February 1991, a set of potted trees was transferred directly without chilling from the plastic house to the 30°/25°C growth chamber. No trees sprouted during the low temperature treatments. New buds sprouted early and more buds sprouted during subsequent exposure to 30°/25°C treatment as the low temperature was prolonged. The number of new shoots for 75-day exposure was greater at 15°/5°C than it was at 10°/10°C regimen and those kept in the plastic house. The number of inflorescences, flower buds, and flowers increased for the 60-day and over exposures, but very few flowers developed after a 15- or 30-day exposure. The numbers of flower buds and flowers per node were 2.27 and 2.05, respectively, for a 75-day exposure under the 15°/5°C regimen, whereas they were 0.81 and 0.76, respectively, in the 10°/10°C regimen. Sugar and carbohydrate contents in leaves increased while the N content decreased under prolonged low temperature treatments. (author)

[en] The authors evaluated the efficacy of CT in the detection of pneumoperitoneum. CT was performed in 38 of 294 cases of gastrointestinal perforation in the past 8 years. In 15 cases (40%), a pneumoperitoneum was detected only with CT. In 19 cases (50%), indications for operation were established on the basis of CT findings such as a hemoperitoneum, mass, or unusual gas accumulation. They stress the importance of scanning the entire liver with a wide window technique in order to image a tiny pneumoperitoneum

[en] Alkylammonium iron(III) complexes, [(n-C_nH_2n+1)mNH_4-m]₃ [Fe(CN)₆] were prepared and studied by Moessbauer spectroscopy, XRD, and DSC. In the complexes with m=2, the temperature dependences of the area intensity of Moessbauer are correlated to the motion of alkyl chains. The temperature dependence of the complex with n=4 was linear and smaller than that of other complexes. Especially in the complex with n=6, the deviation from the linear was the largest in the complexes observed. This result is attributed to the structural difference of the complex. The complexes with n≥8 consist of two-dimensional layer structure. The temperature dependence of the area intensity was similar to each other. This means that the motion of alkyl chain in these complexes are almost the same. The values of quadrupole splitting for the complexes were larger those that of the complexes (m=1). This indicates that the form of [Fe(CN)₆]^3- ion is affected by the differences of the number of alkyl groups. (author)

[en] We report measurements of charged current inclusive and quasielastic interactions of muon neutrinos on carbon with an average energy of 0.8 GeV by SciBooNE experiment at Fermilab. These two results are complementary to understand the neutrino-nuclear interaction in the few-GeV region with effects of final state interactions.

[en] The temperature dependences of the extraordinary Hall effect (EHE) and the polar Kerr effect (PKE) hysteresis loops are measured in amorphous rare-earth (RE) transition metal (TM) films. The polarity of each effect corresponds to that of its TM component. The temperature dependence of Hall voltage is similar to that of the Kerr rotation angle, and, in Gd-Co-Mo films, it is similar to that of Co sublattice moment calculated by Hasegawa's two sublattice model. From these results, both EHE and PKE in RE-TM films are considered to mainly associate with the TM sublattice moment
