Effect of Day Length, Supplemental Lighting Strength, Shading Period and Minimum Night Temperature on Occurrence of Abnormal Inflorescence in Gypsophila paniculata ‘Altair’

As occurrence of abnormal inflorescence in Gypsophila paniculata ‘Altair’ is caused by environmental conditions, effects of day length, supplemental lighting strength, shading period and minimum night temperature on occurrence of abnormal inflorescence were investigated. Abnormal inflorescence was classified into four types : normal, pattern 1 (Short-flower stalk), pattern 2 (Coalescent two-flower stalk) and pattern 3 (Looping and irregular-flower stalk). Neither of 12h, 16h, 20h or 24h day length by fluorescent lamp, nor 24h by incandescent lamp affected occurrence of abnormal inflorescence. Effects of four levels of light intensity (fluorescent lamp : PPFD 1μmol・m−2・s−1, incandescent lamp : PPFD 3μmol・m−2・s−1, metal halide lamp : PPFD 14μmol・m−2・s−1 and high-pressure sodium lamp : PPFD 48μmol・m−2・s−1) were examined in 16h photoperiod. Occurrence of abnormal inflorescence was not affected by different light intensities, neither was it affected by shading period. Occurrence of abnormal inflorescence at 15°C was however significantly reduced compared to that at 8°C. In particular, patterns 2 and 3 at 15°C were significantly reduced compared to those at 8°C. There was a strong negative correlation between average night temperature from starting the treatment to flower budding (7.1°C, 9.0°C, 9.2°C, 11.6°C and 16.4°C) and incidence of pattern 3 (13.1%, 8.7%, 7.1%, 1.1% and 0.7%). Therefore, as average night temperature increased, occurrence of abnormal inflorescence decreased. The results show that low night temperature may be the main factor inducing occurrence of abnormal inflorescence.シュッコンカスミソウ‘アルタイル’の形態異常花序の発生には環境要因が関与していると考えられたので，日長，補光強度，遮光時期および最低夜温が形態異常花序発生に及ぼす影響を調査した．形態異常程度は４種類のパターン (０：正常，１：茎が短いもの，２：２本の茎が癒着，3：ひどく湾曲し変形したもの) に分類し，その影響を受けた小花の割合を求めた．蛍光灯による日長処理（12時間，16時間，20時間，24時間）や白熱灯による日長処理（自然日長，24時間）は形態異常花序発生率に影響を及ぼさなかった．蛍光灯（PPFD 1μmol・m-2・s-1），白熱灯（PPFD 3μmol・m-2・s-1），メタルハライドランプ（PPFD 14μmol・m-2・s-1），高圧ナトリウムランプ（PPFD 48μmol・m-2・s-1）を用いて16時間の補光を行った．異なる光源による光強度でも形態異常発生率に一定の傾向は認められなかった．遮光時期を変えても形態異常発生率に一定の傾向は認められなかった． 最低夜温を15℃に上げると８℃区と比較して15℃区の形態異常発生は大きく減少した．特にパターン２と３の発生率は大幅に低下した．各実験の処理開始から発蕾までの平均夜温（7.1℃，9.0℃，9.2℃，11.6℃，16.4℃）と，パターン３の形態異常発生率（13.1%，8.7%，7.1%，1.1%，0.7%）との間に高い負の相関（R2＝0.849）が認められ，処理開始から発蕾までの平均夜温が高いほど形態異常発生率は低下した．以上のことから，形態異常花序発生には夜間の温度が大きく関与しているのではないかと推察された

Solar Lyman-Alpha Polarization Observation of the Chromosphere and Transition Region by the Sounding Rocket Experiment CLASP

We are planning an international rocket experiment Chromospheric Lyman-Alpha Spectro-Polarimeter (CLASP) is (2015 planned) that Lyman line (Ly(alpha) line) polarization spectroscopic observations from the sun. The purpose of this experiment, detected with high accuracy of the linear polarization of the Ly(alpha) lines to 0.1% by using a Hanle effect is to measure the magnetic field of the chromosphere-transition layer directly. For polarization photometric accuracy achieved that approx. 0.1% required for CLASP, it is necessary to realize the monitoring device with a high throughput. On the other hand, Ly(alpha) line (vacuum ultraviolet rays) have a sensitive characteristics that is absorbed by the material. We therefore set the optical system of the reflection system (transmission only the wavelength plate), each of the mirrors, subjected to high efficiency of the multilayer coating in accordance with the role. Primary mirror diameter of CLASP is about 30 cm, the amount of heat about 30,000 J is about 5 minutes of observation time is coming mainly in the visible light to the telescope. In addition, total flux of the sun visible light overwhelmingly large and about 200 000 times the Ly(alpha) line wavelength region. Therefore, in terms of thermal management and 0.1% of the photometric measurement accuracy achieved telescope, elimination of the visible light is essential. We therefore, has a high reflectivity (> 50%) in Ly line, visible light is a multilayer coating be kept to a low reflectance (<5%) (cold mirror coating) was applied to the primary mirror. On the other hand, the efficiency of the polarization analyzer required chromospheric magnetic field measurement (the amount of light) Conventional (magnesium fluoride has long been known as a material for vacuum ultraviolet (MgF2) manufactured ellipsometer; Rs = 22%) about increased to 2.5 times were high efficiency reflective polarizing element analysis. This device, Bridou et al. (2011) is proposed "that is coated with a thin film of the substrate MgF2 and SiO2 fused silica." As a result of the measurement, Rs = 54.5%, to achieve a Rp = 0.3%, high efficiency, of course, capable of taking out only about s-polarized light. Other reflective optical elements (the secondary mirror, the diffraction gratingcollector mirror), subjected to high-reflection coating of Al + MgF2 (reflectance of about 80%), less than 5% in the entire optical system by these (CCD Science was achieved a high throughput as a device for a vacuum ultraviolet ray of the entire system less than 5% (CCD of QE is not included)

Development of Flight Slit-Jaw Optics for Chromospheric Lyman-Alpha SpectroPolarimeter

In sounding rocket experiment CLASP, I have placed a slit a mirror-finished around the focal point of the telescope. The light reflected by the mirror surface surrounding the slit is then imaged in Slit-jaw optical system, to obtain the a-ray Lyman secondary image. This image, not only to use the real-time image in rocket flight rocket oriented direction selection, and also used as a scientific data showing the spatial structure of the Lyman alpha emission line intensity distribution and solar chromosphere around the observation area of the polarimetric spectroscope. Slit-jaw optical system is a two off-axis mirror unit part including a parabolic mirror and folding mirror, Lyman alpha transmission filter, the optical system magnification 1x consisting camera. The camera is supplied from the United States, and the other was carried out fabrication and testing in all the Japanese side. Slit-jaw optical system, it is difficult to access the structure, it is necessary to install the low place clearance. Therefore, influence the optical performance, the fine adjustment is necessary optical elements are collectively in the form of the mirror unit. On the other hand, due to the alignment of the solar sensor in the US launch site, must be removed once the Lyman alpha transmission filter holder including a filter has a different part from the mirror unit. In order to make the structure simple, stray light measures Aru to concentrate around Lyman alpha transmission filter. To overcome the difficulties of performing optical alignment in Lyman alpha wavelength absorbed by the atmosphere, it was planned 'following four steps in order to reduce standing time alignment me. 1. is measured in advance refractive index at Lyman alpha wavelength of Lyman alpha transmission filter (121.567nm), to prepare a visible light Firuwo having the same optical path length in the visible light (630nm).2.

Effect of Pictorial Depth Cues, Binocular Disparity Cues and Motion Parallax Depth Cues on Lightness Perception in Three-Dimensional Virtual Scenes

Surface lightness perception is affected by scene interpretation. There is some experimental evidence that perceived lightness under bi-ocular viewing conditions is different from perceived lightness in actual scenes but there are also reports that viewing conditions have little or no effect on perceived color. We investigated how mixes of depth cues affect perception of lightness in three-dimensional rendered scenes containing strong gradients of illumination in depth.Observers viewed a virtual room (4 m width x 5 m height x 17.5 m depth) with checkerboard walls and floor. In four conditions, the room was presented with or without binocular disparity (BD) depth cues and with or without motion parallax (MP) depth cues. In all conditions, observers were asked to adjust the luminance of a comparison surface to match the lightness of test surfaces placed at seven different depths (8.5-17.5 m) in the scene. We estimated lightness versus depth profiles in all four depth cue conditions. Even when observers had only pictorial depth cues (no MP, no BD), they partially but significantly discounted the illumination gradient in judging lightness. Adding either MP or BD led to significantly greater discounting and both cues together produced the greatest discounting. The effects of MP and BD were approximately additive. BD had greater influence at near distances than far.These results suggest the surface lightness perception is modulated by three-dimensional perception/interpretation using pictorial, binocular-disparity, and motion-parallax cues additively. We propose a two-stage (2D and 3D) processing model for lightness perception

Ventricular premature contraction in hypertrophic cardiomyopathy and essential hypertension with left ventricular hypertrophy : comparison of Holter ECG, UCG and stress thallium-201 myocardial scintigraphy findings

In order to investigate the relationship of different morbid states of the hypertrophied myocardium to the appearance of ventricular premature contraction (VPC), we compared the VPC findings from Holter ECG with those of UCG and stress thallium-201 myocardial SPECT scintigraphy (stress scinti) in 31 patients with hypertrophic cardiomyopathy (HCM) and 20 with essential hypertension (HT). The HCM patients consisted of 21 with asymmetric hypertrophy (ASH), 3 with symmetric hypertrophy (SH), and 7 with apical hypertrophy (APH). We recognized positive findings on the stress scinti such as fixed perfusion defect (FD) or reversible perfusion defect (RD) in 11 patients (ASH 10, APH 1) out of 31 patients with HCM (35%). Positive findings were observed in only one patient out of 20 with HT (5%). We recognized a high grade VPC (grade 4a and 4b of Lown's criteria) in 8 of 11 scinti positive patients with HCM (ASH 7, APH 1) (73%), while high grade VPC appeared in 5 (all of them are ASH) out of 20 scinti negative patients with HCM (25%). Therefore, these findings suggest that high grade VPCs in HCM occur in relation to a myocardial perfusion defect
