No full text鉄骨構造物において筋違は重要な耐震, 耐風要素であり, 筋違付骨組の挙動を明らかにすることは非常に重要である。水平力を受ける筋違付骨組は, 筋違と骨組との相関関係により複雑な挙動を示すので, 筋違と骨組の各々の履歴特性を重ね合せることにより, 筋違付骨組の挙動を明らかにしょうとする試みがなされてきた1)。しかしながら, この重ね合せの方法によれば, 筋違と骨組の相関関係, すなわち筋違が骨組から受ける影響, および筋違が骨組に及ぼす影響が考慮されていないことになる。前者は, 骨組の変形により筋違が材端で受ける変形拘束の影響であり, 後者は筋違による柱の軸力変動の影響や, 筋違の曲げ変形による材端での曲げの影響等がある。これらの相関関係の影響についての研究は数少ない。本報告では, これらの相関関係のうち, 特に筋違が骨組から受ける影響を解析的に明らかにしようとするものである。It is important in the study of elastic-plastic behaviour of braced frames to investigatethe interaction effects between the frame and the bracing. This paper presents anelastic-plastic analysis on the behaviour of a bar subjected to compulsive end displacement, inorder to evaluate the effect of end restraints caused by the frame deformation. The incre-mental load-deflection relation is obtained by introducing a simplified mathematical model, andit is comfirmed that the effects of the end restraints are not so important. The numericalresults show a good agreement with experimental ones.鉄骨構造物において筋違は重要な耐震,耐風要素であり,筋違付骨組の挙動を明らかにすることは非常に重要である。水平力を受ける筋違付骨組は,筋違と骨組との相関関係により複雑な挙動を示すので,筋違と骨組の各々の履歴特性を重ね合せることにより,筋違付骨組の挙動を明らかにしょうとする試みがなされてきた1)。しかしながら,この重ね合せの方法によれば,筋違と骨組の相関関係,すなわち筋違が骨組から受ける影響,および筋違が骨組に及ぼす影響が考慮されていないことになる。前者は,骨組の変形により筋違が材端で受ける変形拘束の影響であり,後者は筋違による柱の軸力変動の影響や,筋違の曲げ変形による材端での曲げの影響等がある。これらの相関関係の影響についての研究は数少ない。本報告では,これらの相関関係のうち,特に筋違が骨組から受ける影響を解析的に明らかにしようとするものである。It is important in the study of elastic-plastic behaviour of braced frames to investigatethe interaction effects between the frame and the bracing.

An experimental approach to study the biosynthesis of brominated metabolites by the red algal genus Laurencia
No full textThe production of labeled brominated metabolites with radioactive 82Br in Laurencia species was investigated as part of a study of the biosynthesis of halogenated metabolites from species belonging to the red algal genus Laurencia (Rhodomelaceae, Ceramiales). Radiobromide [82Br], thin-layer chromatography (TLC), and TLC-autoradioluminography (ARLG) were used. When cultured in artificial seawater medium (ASP12NTA including Na82Br) under 16:8 h light:dark (LD) illumination cycles for 24 h, each of the strains of Laurencia, Laurencia japonensis Abe et Masuda, Laurencia nipponica Yamada (laurencin-producing race and laureatin-producing race), and Laurencia okamurae Yamada, produced species- (or race-) specific 82Br-containing metabolites. In the case of the laurencin-producing race of L. nipponica, laurencin and deacetyllaurencin were found to be produced in approximately 1:1 ratio, though laurencin is the major metabolite in the wild sample. Furthermore, when cultured in the dark, the production rates of brominated metabolites in Laurencia spp. were found to be diminished. The present study strongly indicates that the use of radiobromine [82Br] in combination with the TLC-ARLG method is an effective approach for investigating the biosynthesis of brominated metabolites in Laurencia
Phylogenetic affinities of genera Acanthopeltis and Yatabella (Gelidiales, Rhodophyta) inferred from molecular analyses
No full textPhylogenetic affinities of Acanthopeltis japonica Okamura and Yatabella hirsuta Okamura were determined from nucleotide sequences of the nuclear-encoded small subunit rDNA (SSU), internal transcribed spacer 1 (ITS1), and plastid-encoded large subunit of the ribulose-1,5-bisphosphate carboxylase/oxgenase gene (rbcL). We have sequenced an additional nine species of Japanese gelidialean species. Although Acanthopeltis and Yatabella had been suggested to be derived from separate lineages by researchers who emphasized the difference of growth pattern, they were recognized as a monophyletic group in the SSU, ITS1, and rbcL analyses. We have also demonstrated that Acanthopeltis and Yatabella possess a fundamentally similar type of growth pattern. The molecular data and morphological similarities indicate that Acanthopeltis and Yatabella are congeneric. The new combination, Acanthopeltis hirsuta (Okamura) Shimada, Horiguchi et Masuda, comb. nov., is proposed. Additional information on phylogenetic relationships within the Gelidiales was obtained. Our phylogenetic analyses of the Gelidiales using the above genes show three major clades, the Gelidiella clade that was the earliest diverging group within the order, a Pterocladia/Pterocladiella clade, and a large Gelidium-complex clade. The large Gelidium-complex clade is composed of the Ptilophora clade, Capreolia clade, and Gelidium-complex clades. In the rbcL and ITS1 trees, the Gelidium-complex clade includes three subclades, one of which is recognized for the first time and includes Acanthopeltis/Yatabella, Onikusa japonica (Harvey) Akatsuka, and Gelidium vagum Okamura, all distributed in the western and eastern Pacific. The type of secondary rhizoidal attachment, the unicellular independent type, peg type, and brush type, is consistent with the respective three major clades of the Gelidiales, suggesting that this morphological character reflects the phylogeny of this order
Tone sandhi rule for pattern substitution in Suzhou Chinese : Verification using words beginning with a Ru syllable
No full text1.はじめに 2.トーン交替規則 3.調査1 4.入声音節で始まる3音節語 5.調査2 6.パターン代入規則の成立過程 7.おわりにIt is well known that in Wu Chinese, there exists a type of tone sandhi that deletes tones from non-initial syllables and spreads the remaining tones to the whole word. In Suzhou dialect, a dialect of Wu Chinese, there is another type of tone sandhi, named pattern substitution, which alternates underlying tonal patterns of initial syllables with other tonal patterns. Masuda (2011) tried to show that pattern substitution in Suzhou dialect is not lexically determined, or in other words it is not the remnant of historical tonal alternation, but is caused by synchronic rules. He also presented the forms that these rules take. However, data of his work are restricted to words that do not include a syllable whose coda is a glottal stop, that is, Ru syllable, so pattern substitution in words that include a Ru syllable remains unexplained. This study examines novel loanwords created by the author with the Ru syllable as the first syllable. The result shows that pattern substitution is observed in these loanwords, although its realization is different from words which do not include Ru syllables. This finding supports the view that pattern substitution in Suzhou dialect is caused by the rules presented in Masuda (2011)
Explanation of the Plates: Two Fragments of the “Animal Scroll” (Choju Giga): A Newly Discovered Fragment and the Fragment from the Former Masuda Collection
No full textIn addition to the four celebrated scrolls of satirical drawings of animals and people which are preserved in the Kōzanji, Kyoto, three fragments, comparable both in subject and style to the first scroll, have long been known: 1) in Tokyo National Museum, 2) in the former Masuda Collection, and 3) in the collection of Mr. A. B. Martin, Brooklyn Museum, New York. The author presents here a new fragment of the same type which was discrovered last year in a private collection. By reproducing it beside the Masuda fragment, it may likewise be compared with the first Kōzanji scroll and in this way its authenticity may be determined.
The long “Masuda fragment” (Pls. V to VII: 119.2 x 29.2 cm) presently in a private collection, is in fact an ingenious assemblage of three separate fragments (fig. 5). On the right a monkey is shown exercising his mount (a deer) before his adversary, a rabbit who is seated on the back of a fox. To the left to this scene there appears a well disguised vertical connection which passes just between the small rabbit and monkey who are situated at the lower edge of the composition. This is followed by a central scene representing a race between the rabbit and the monkey over a low ground accentuated with autumn grasses. Among the five scrolls of the Sumiyoshi copies dated 1598, there is one which is not preserved among the originals in the Kōzanji, The first two scenes of the “Masuda fragment” are found in the middle section of this scroll. But the third scene in the “Masuda fragment” which shows a fox, turtle, frog, crane and duck as spectators of the race, is found in a slightly different variation toward the end of the same Sumiyoshi scroll instead.
The new fragment (Pl. IV; 51,6 X 29.1 cm) shows a monkey-nun, a lady fox, etc., walking in an autumn setting. In the Sumiyoshi copy cited above, this particular scene is situated just after the composition represented by the “Martin fragment”, also related to the race episode, which shows the monkey fallen from his mount. The position of the new fragment is confirmed by an examination of the traces of damage which occur across the surfaces of the three fragments (see the article by Mr. Kenji Ueno in this number). The pattern of the damage is similar to that shown in the first ten sheets of the first Kōzanji scroll. After a close examination of the condition of the two fragments, it may be said that the paper resembles that of the first roll in quality, but is not as well preserved. Similarly, the ink lines have faded and are sometimes retouched or obliterated. If it is certain that these two fragments originally belonged to a long composition which preceded the existing first part of the first Kāzanji scroll at the time of the temple fire in the middle of the sixteenth century, it must be confirmed that the drawing of these fragments is really identical to the first scroll in technique and style.
Moreover, in the course of comparison, it was discovered that, contrary to previous opinions, the first scroll seems to have been drawn by two different artists. The first hand appears in sheets 1 to 10 (Pl. VIII) and the second hand in the remainder of the scroll (Pl. IX). The drawing of the Masuda, Martin, and newly-discovered fragments resembles, in use of the brush, touches and accents, the style of the first section of the first Kōzanji scroll, and suggests that they were indeed executed by the same person.journal articl
