The present study reports the chromosome number and meiotic behavior including microsporogenesis of Actaea kashmiriana J. Compton and its relation with pollen fertility and seed set. The species showed a chromosome count of 2n=4x=32 and meiotic chromosomal irregularities such as chromatin stickiness, cytomixis, laggard formation, chromosomal bridges, micronuclei and polysporads. B-chromosomes were also observed in this species. Due to these meiotic irregularities, reduced pollen fertility was observed in the range of 85–87%, and the seed set was also significantly reduced to 67.16 to 70.45%.

1920年代から『婦人画報』などの一部の婦人雑誌で批判され, 谷崎潤一郎の『細雪』などにも描かれた公衆場面での化粧行動であるが, 1990年代に入ると再び社会的な話題となった.若者たちは, 公衆場面で化粧を行うことをどのようにとらえているのか, 本研究では大学生762名 (男性414人, 女性348人) を対象に, 化粧行動の許容に関わる公衆場面の構造を明らかにし, 個人差要因との関連性について検討を行った.1) 8項目の公衆場面それぞれについて, 7項目の化粧行動を行うことをどの程度許容できるか, 因子分析により構造化を試みた結果, 『電車・駅での化粧』『化粧品コーナーでの化粧』『友人の家での化粧』『多場面でのリップクリーム』『授業中教室での化粧』『学食での化粧』『休み時間教室での化粧』『多場面での油とり』『飲食店での化粧』が明らかとなり, その構造は場面により構成されていることがわかった.そして, 『授業中教室での化粧』『友人の家での化粧』『多場面でのリップクリーム』『多場面での油とり』について, 許容に男女差のあることがわかった.2) 男性では私的自意識や外的他者意識が, 女性では外的他者意識や公的自意識や私的自意識が化粧行動の許容に影響を与えることから, 自己や他者の外面への注意の向けやすさだけではなく, それに伴う態度と行動の一貫性や非一貫性などが, 化粧行動の許容に影響していることがわかった.

Monitoring and quantifying hydrological flows in the vadose zone is complicated to analyze due to the effects of rainfall in the tropics, the dynamic interactions among rains, the vegetation layer, moisture in the soil, and the entire regolith. Quantifying subsurface hydrological flows at specific scales and high resolution presents further difficulties. To overcome these issues, resistivity methods can play an important role. This paper examines the results of gravimetric moisture content monitoring in the Panamanian tropics through time-lapse electrical resistivity tomography analysis. Changes in the electrical properties of soil were quantified through six tomographic tests performed between February 2012 and March 2013 along with a profile. Significant changes in resistivity were identified between February (dry season) and May, and August and October (rainy season), with negative percentages (–60%) indicating the effects of rain infiltration at the surface and positive percentages (60%) linked to moisture absorption in the soil, electrode relocation for each test or inversion processes. Additional laboratory analyses of soil samples were carried out to obtain gravimetric moisture content tomograms. The changes of this parameter in the subsurface horizons, and the percentage differences in the calculated resistivity values, are helpful for determining the impact of rain on the soils.

Genetically engineered animals can be produced quickly using genome editing technology. A new electroporation technique, technique for animal knockout system by electroporation (TAKE), aids in the production of genome-edited animals by introducing nucleases into intact embryos using electroporation instead of microinjection. It is difficult to confirm nuclease delivery into embryos after electroporation using the conventional TAKE method. We previously reported the successful visualization of fluorescently-labeled tracrRNA in embryos after electroporation Cas9 paired with the crRNA:tracrRNA-ATTO550 duplex. However, the amount of fluorescence signal from labeled tracrRNA in embryos did not correlate with the genome editing rate of the offspring. This study examined the visualization of Cas9 protein in embryos after electroporation and its correlation with the genome editing rate of the offspring using a fluorescent Cas9 fusion protein. The fluorescent Cas9 protein was observed in all embryos that survived following electroporation. We found that the efficiency of Cas9 protein delivery into embryos via electroporation depended on the pulse length. Furthermore, we demonstrated that the amount of fluorescent Cas9 protein detected in the embryos correlated with the genome editing efficiency of the embryos. These data indicate that the TAKE method using fluorescently-labeled nucleases can be used to optimize the delivery conditions and verify nuclease delivery into individual embryos prior to embryo transfer for the efficient production of genome-edited animals.

Samples of trinitrotoluene (TNT) and erythritol tetranitrate (ETN) were exposed to nanosecond pulses from a tunable laser source across 90 minutes. During this continued laser pulse exposure, the samples of TNT underwent heavy degradation while the samples of ETN were able to resist high energy densities without visible alteration. A degradation pathway involving a nitro-nitrite rearrangement is suggested for the TNT, which sees radical production result in carbon ‘char’ formation in the explosive, despite there being no signs of bulk or surface melting. The formation of this carbonexplosive mixture and its implications towards the safety of extended exposure laser sensing techniques is discussed.

To overcome the limitation of low network density and sparse distribution of meteorological stations, spatial interpolation is being performed for estimating meteorological variables that are not geographically covered by existing observation network. While there are several readily available spatial interpolation techniques, it is still difficult to determine which one best estimates actual observation. Considering the stimulus for disaster risk reduction, hydrological, agricultural, and other applications of interpolated data, this study compared six interpolation techniques (Inverse Distance Weighted (IDW), Completely Regularized Spline (CRS), Tension Spline (TS), Ordinary Kriging (OK), Universal Kriging (UK), and ANUSPLIN) that have been recommended in tropical maritime region. Validation results comparing historical monthly and interpolated rainfall data from 1981-2010 in 65 stations in the Philippines show that OK has the best performance among the aforementioned techniques followed by ANUSPLIN and TS. Ultimately, this study is a contribution to the existing inadequate literatures that have documented and evaluated interpolation techniques that can be used in archipelagic regions with prominent climate variability.

Organic electronics is an extensively studied subject opening new horizons in electronics technology. It has attracted great attention as a technology to enable flexible electronic devices through solution processing of organic and polymeric materials. However, patterning of organic materials to construct device components still remains one of the major hurdles to be overcome due to problems with chemical processing. Fundamentally this challenge originates from the limited number of options regarding orthogonal solvents. Recently, we have identified supercritical carbon dioxide (scCO2) and segregated hydrofluoroethers (HFEs) as universal, non-damaging solvents for most non-fluorinated polymeric materials. These unconventional solvents expand processing options from the two-dimensional plane to three-dimensional space by drawing another orthogonal axis. Taking advantage of those noble solvents and fluorinated photoresists, we were able to make patterns of functional organic materials photolithographically. Furthermore, our orthogonal processing method has been applied to the fabrication of a patterned polymer light-emitting device in scCO2 and an organic thin-film transisotor in HFEs.
