In order to promote increases in the size of ‘Kosui’ Japanese pear [Pyrus pyrifolia (Burm.) Nakai] fruit by plant growth regulators, we applied gibberellin (GA)3+4 paste [2.7% (w/w), A3:A4 = 90:10] in combination with prohexadione-calcium [1%, PCa; BAS-125 (3-oxido-4-propionyl-5-oxo-3-cyclohexene-carboxylate)], an inhibitor of GA 2β-hydroxylation that catabolizes active GA into an inactive form, to fruit pedicels at approximately 30 days after full bloom. GA3+4+PCa treatment advanced fruit growth only in the early stages, but fruit weight did not show any significant differences between the untreated control and GA3+4+PCa-treated fruits at harvest. In contrast, when GA4+7 [2.7% (w/w), A4:A7 = 66:34] was applied, the fruit weight at harvest was greater than that of untreated fruit. Moreover, GA4+7 treatment in combination with PCa resulted in an even higher fruit weight at harvest. The GA4 concentration in fruit flesh was not affected by GA3+4 application at 1 week after the treatment (WAT) either with or without PCa, but GA4 levels increased with GA4+7+PCa treatment, resulting in a significant increase in fruit weight at harvest. A single GA4+7 application almost doubled the GA4 concentration compared with the untreated control, but the difference was not significant. These results indicate that fruit weight at harvest was greater when the GA4 concentration was higher in the fruit flesh at 1 WAT. The higher concentration of GA4 in the GA4+7+PCa-treated fruit compared with the GA4+7 treatment alone may be attributed to the function of PCa that acts to prevent the inactivation of GA4 to GA34 by inhibiting 2β-hydroxylation.

Five iridoid glycosides, including the two new compounds scropolioside-D2 (1) and harpagoside-B (2), were isolated from the aerial parts of Scrophularia deserti DEL (Scrophulariaceae). Their structures were elucidated on the basis of spectral data to be 6-O-[2″,4″-di-O-acetyl-3″-O-trans-cinnamoyl)-α-L-rhamnopyranosyl]-8α-hydroxymethyl-1α,5β,6α,7α,9β-pentahydro-7(8)-epoxy-2-oxaind-3-ene-1-O-β-D-glucopyranoside-6′-O-acetate (1) and 5-O-β-hydroxy-8-O-β-trans-cinnamoyl-8α-methyl-1,6,7,9-tetrahydro-2-oxaind-3-ene-1-O-β-D-glucopyranoside (2), respectively. In addition, three more iridoid glycosides, scropolioside-D (3), koelzioside (4), and 8-O-acetyl-harpagide (5), were also isolated and characterized from this source. The biological activity and the structure activity relationship of the compounds were also studied, and scropolioside-D (3) and harpagoside-B (2) were found to possess significant antidiabetic and antiinflammatory activity, respectively.

How does a reciprocal communal sharing system come into existence in a sustainable form in human societies? The anthropological literature has provided two explanations for the origin of communal sharing under uncertainty: risk reduction by social sharing (Kaplan & Hill, 1985) and tolerated theft (Blurton Jones, 1984, 1987; Winterhalder, 1986, 1996). In this paper, we aim to develop a third explanation focusing on the emergence of a communal sharing norm. A communal sharing norm here refers to a social norm designating uncertain resources as common properties. A series of computer simulations based on an evolutionary game framework suggests that such a communal sharing norm is indeed evolvable. We argue that the evolutionary game analysis can be a powerful tool in cognitive science to derive empirical hypotheses concerning various cognitive and behavioral mechanisms.

The physicochemical properties, fatty acid profiles, content of tocopherol and sterol of the oils extracted from the nuts of Elaeagnus mollis Diels grown in different regions of China were studied in this work. The results indicated that the Elaeagnus mollis Diels nut oils contained about 0.2% sterols and the tocopherol contents were in the range of 119.6-128.6mg/100g. The nut oils were all rich in unsaturated fatty acids, especially oleic acid and linoleic acid. Furthermore, the main triacylglycerols species of the nut oils were all dilinoleoyl-monoolein (LOL), dioleoyl-monolinoleoyl (OLO) and trilinoleate (LLL). This work might be useful for developing applications for Elaeagnus mollis Diels nut oil.

沖縄本島北部の森林の除伐が腐朽木に生息する捕食性アブ類群集に与える影響を明らかにするため, 国頭村西銘岳周辺において, 林床に存在するさまざまなサイズ・腐朽度合いの腐朽木の体積, および, それらから発生する捕食性アブ類の個体数を調査した。未除伐林とその後の経過年数が異なる除伐林が入り混じる森林では, さまざまなサイズと腐朽度からなる腐朽木が不均一に分布しており, それによってそれぞれの林分で生息する捕食性アブ類の個体数が異なった。また, 捕食性アブ類の科構成は除伐後 1 年経過した林分と除伐後 7 年以上経過した林分で異なった。羽化トラップで得られた捕食性アブ類は腐朽木の体積に対応して増減し, アシナガバエ科の個体数も同様に増減した。特に, 除伐による, 腐朽度合いが軽度の腐朽木の大量発生は, キクイムシ類を介して, キマワリアシナガバエ属 Medetera の個体数に対する間接的なボトムアップ効果があると考えた。沖縄本島北部では, 林内の腐朽木の体積が大きく変動することなく, かつ, 異なるサイズと腐朽度合いの腐朽木が存在するような森林管理が捕食性アブ類の多様性を維持すると考えた。

Summer-to-autumn-flowering small-flowered spray-type (SAFS) chrysanthemums (Chrysanthemum morifolium Ramat.) are commercially important in Japan, and there is an occasional increased demand for these flowers. However, under current cultivation methods, the quality of spray formations is compromised in order to maintain a sufficient production rate at times of peak demand. This study investigated the effect of interrupted lighting (IL), the intercalation of a period of long days (by night interruption) into the natural day length (NDL) period of growing, in order to regulate spray formations in SAFS chrysanthemum cultivars ‘Haruka’ and ‘Subaru’, in which lighting can markedly delay flowering. The effects of the NDL period before IL and those of the IL period were investigated. First, we investigated the effect of 2–12 days of NDL followed by 12 days of IL. Plants subjected to 2–6 days of NDL had longer flower clusters and a greater number of flower buds on the upper lateral flower stems and developed a broom-like spray. Next, we investigated the effect of 4–20 days of IL after 4 days of NDL. Plants subjected to 8–20 days of IL had longer flower clusters, more flower buds on the upper lateral flower stems, and broom-like sprays. These changes were more pronounced when the IL periods were prolonged. Our results showed that spray formation in SAFS chrysanthemum cultivars ‘Haruka’ and ‘Subaru’ can be regulated by controlling the timing and period of IL.

It has been reported that the standardized mortality ratios (SMRs) of biliary tract cancer (BTC) (female gallbladder cancer (GBC) in particular) are high in the Niigata plain and low in other parts of Niigata Prefecture. Based on epidemiological studies, the presence of environmental water pollution by agricultural chemicals is likely to be associated with the occurrence of GBC, and one of the most suspected of these is a diphenylether herbicide, chlornitrofen (CNP).The purpose of the present study was to investigate whether or not there was a difference in concentrations of CNP and its reduction product (CNP-amino) in river and faucet water between Niigata and Joetsu Cities, which are located in the Niigata plain and another part of Niigata, respectively. By employing a new method for CNP and CNP-amino extraction, the detection of CNP and CNP-amino was undertaken by using a gaschromatograph with an electroncapture detector.The maximum levels of CNP concentrations were 871 and 554ng/l in river and faucet water, respectively on May 6, 1992 in Niigata City. The concentration of CNP in faucet water was well correlated with that in river water. In Joetsu City, the maximum concentration in river water was 183ng/l on May 6 and had decreased rapidly towards the background level on July 29, 1992. As to the concentrations of CNP in faucet water in Joetsu City, they fluctuated between the levels of 2 and 9ng/l. In the case of CNP-amino concentrations in faucet water, a clear-cut difference was evident between the two cities; 384ng/l in Niigata and under the quantity limit in Joetsu.Examination of CNP and CNP-amino concentrations in faucet water was made in Murakami, Gosen and Kamo Cities, where the SMRs for female GBC were insignificant even in the midst of the Niigata plain. It was demonstrated that concentrations of CNP and CNP-amino were as low as in Joetsu City. The levels of pollution of faucet water with CNP and CNP-amino were well correlated with the SMRs of BTC, especially female GBC.

The method of the inversion analysis to evaluate the distribution of seismic energy radiated from an earthquake fault plane based on seismic intensity distribution data has been developed. The fault plane is divided into small sub-faults. The optimized seismic energy distribution of each sub-fault is calculated using the least square method to minimize the error between evaluated and observed seismic intensities.The energy distribution of a seismic fault is related to seismic intensity using the attenuation formula with equivalent hypocentral distance. The parameters of the attenuation formula are obtained from a regression analysis with measured seismic intensity data of recent moderate earthquakes.The forward analyses using an assumed model are performed to verify the accuracy of the inversion analysis and to evaluate the effect of factors such as the standard deviation of seismic intensity, constraint condition of inversion analysis and configuration of observation stations.Finally, the method is applied to the Showa Tonankai earthquake in 1944 and the Showa Nankai earthquake in 1946 and the result is compared with the tsunami and strong motion waveform inversion results to confirm the efficiency and applicability of the method.

To make clear the features of the spectrum splitting due to the introduction of a soft solid core, the frequency and spectral amplitude of torsional oscillations are calculated for the modes with colatitudinal order number n from 2 to 9, assuming GUTENBERG-BULLEN A′ earth model. The only deviation from the G-B model is the assumption that the distribution of rigidity is constant in the core. The possibillity of estimating the rigidity of the core by the use of spectrum splitting was discussed.

The equation of equilibrium of a homogeneous and isotropic elastic medium is solved for the orthogonal curvilinear coordinates of two dimensions under the condition that Laplace's equation is separable. Coordinates systems satisfying these conditions are Cartesian, cylindrical, elliptic cylindrical and parabolic cylindrical ones.First, solutions of equation of motion is obtained. Then, making frequency in these solutions to zero, the equation of equilibrium is solved.

For the study of macroscopic characteristics of earthquake, it is necessary to investigate both historical and modern earthquakes from the same point of view. Historical earthquakes present informations on damages only. Modern earthquakes have various kind of data obtained from instrumental observations. Intensity data is common to both old and modern earthquakes. As the first step to study historical earthquakes, we studied the seismic intensity distribution of recent earthquakes, in the Tohoku district, which occurred in the interval from 1926 to 1990. Results are summarized as follows.(1) The isoseismal contours for many earthquakes off the Pacific coast elongate to north and south, and the seismic intensity decays steeply across the line which is almost parallel to the volcanic front. We call this line “Steeply Decay Line of Seismic Intensity (SDLSI)”. On the contrary, the distribution of seismic intensity for shallow inland earthquakes doesn't show this tendency.(2) We investigated the seismic intensity attenuation in the Tohoku district and obtained the next formula, I=A-BXwhere, I is the seismic intensity, X the hypocentral distance. Coefficients A and B are expressed as follows:for earthquakes of G1, G2 and G3 (see Fig. 2)A=0.198+0.679M, A/B=-1332+299.9M (east side of SDLSI), A=0.944+0.589M, A/B=-1329+279.5M (west side of SDLSI).for earthquakes of G4A=-1.315+0.912M, A/B=-410+134.9M(3) For the earthquakes along the plate boundary, we defined relatively low- and high-frequency earthquakes according to the value of MJ-MI, where MJ is JMA magnitude and MI the one determined by comparing observed intensity attenuation data of each earthquake with a curve calculated from formulas in (2). The epicenteral distribution of low- and high-frequency earthquakes does not show clear characteristics. But, off Fukushima Prefecture region, there seems to be a boundary of the high-and low-frequency earthquake's distribution along the plate boundary of about 40km depth. The high-frequency earthquakes are found in the west side of the boundary.
