日本外務省による大谷家文書調査

2016-03-31The Ministry of Foreign Affairs of Japan believes that Takeshima is a part of Japanese territory. This belief has been derived from a series of works by Kawakami Kenzo, which came to fruition in "A Historical and Geographical Study of Takeshima (1966)." Kenzo's argument concerning the Edo period was founded on an investigation of the historical archives of the Otani family's documents by the Ministry of Foreign Affairs of Japan (Kenzo actually conducted the investigation). This paper comprehensively examines the reflection of the aforementioned investigation in "A Historical and Geographical Study of Takeshima" and discusses the structure of the current views of the Ministry of Foreign Affairs of Japan.departmental bulletin pape

Observations of NH2D toward Dark Molecular Clouds

The 1a11-1s01 transition of NH2D at 110.1536 GHz was surveyed toward 16 cores of high ammonia abundance in 14 cold dark clouds and was detected toward eight cloud cores, L1448, B1, L1489N, L1551N, L1641N, L134N(S), ρ Oph E, and L63, where L134N and L63 are not associated with infrared sources. The column densities of NH2D were compared with those of the main species NH3, previously determined for the corresponding sources, and the relative abundance, [NH2D]/[NH3], was found to be large, 0.025-0.18, which is among the highest deuterium fractionation so far observed. The relative abundance is remarkably larger than a predicted value by the latest gas-phase chemical model for dark clouds by Howe & Millar. The spectral line of NH2D was not detected in other dark cloud cores. These results suggest that a part of NH3 in dark clouds could originate from dust related reactions associated with energetic events.othe

Proposal of Failure Criterion Applicable to Finite Element Analysis Results for Wall Thinned Pipes under Bending Load

In this paper, a failure criterion applicable to large strain finite element analysis results is proposed to predict the limit bending load of the wall-thinned straight pipes. The criterion, named as the “Domain Collapse Criterion", can handle cases for both collapse and cracking. The criterion evaluates the limit load corresponding to collapse as the load when the Mises stress exceeds the true yield strength of a material for whole "volume" with the nominal wall thickness of the straight pipe. On the other hand, the criterion evaluates the limit load corresponding to cracking as the load when the volume where Mises stress exceeds the true tensile strength penetrates the wall thickness. Results showed that the proposed criterion can estimate the experimental limit moment within approximately 20% difference, regardless of the flaw aspect ratio.othe
