A Remark on Infinite Dimensional Gaussian Integral in a Sobolev Space

In [2] (∞-p)-form on a k-th Sobolev space Wk(X), X a compact (spin) manifold, was defined by using Sobolev duality. Integrals of (∞-p)-form on an (∞-p)-form on a cube in Wk(X) were defined without using measure. We show when the lenghth of sides of the cube tends to ∞, infinite dimensional Gaussian integral that is principal on application converges if and only if the cube is imbedded in Wk(X), k<-d+1/2.Article信州大学理学部紀要 32(2): 61-67(1998)departmental bulletin pape

Josephson junction in cobalt-doped BaFe2As2 epitaxial thin films on (La, Sr)(Al, Ta)O3 bicrystal substrates

Josephson junctions were fabricated in epitaxial films of cobalt-doped BaFe2As2 on [001]-tilt (La,Sr)(Al,Ta)O3 bicrystal substrates. 10m-wide microbridges spanning a 30-degrees-tilted bicrystal grain boundary (BGB bridge) exhibited resistively-shunted-junction (RSJ)-like current-voltage characteristics up to 17 K, and the critical current was suppressed remarkably by a magnetic field. Microbridges without a BGB did not show the RSJ-like behavior, and their critical current densities were 20 times larger than those of BGB bridges, confirming BGB bridges display a Josephson effect originating from weakly-linked BGB

RELATION BETWEEN RELEASE PARAMETERS AND THROWING DISTANCE OF THE JAVELIN THROW

The present study was clarified a three-dimensional examination of the relation between the release parameters and throwing distances, in order to understand the initial flight characteristics of javelins. The subjects were 57 right-handed javelin throwers. The measured throwing distances ranged from 45.25 m to 87.17 m. The elite throwers had tendency to significant positive correlation between theoretical distance and initial velocity of javelin release. Throwers who achieved throwing distances of over 70m were observed to have throwing distances that were shorter than their theoretical distances, while those whose throwing distances were under 70 m group had throwing distances that were longer than their theoretical distances. When the data were applied to initial velocity of javelin release, it was equivalent to 26 m/s

The quantitative determination of volatile fatty acids in ensilage by counter current distribution apparatus

1,本実験において著者等は,Ensilage中のV.F.AsをPaper partition chromatographyとCounter current distribution法によつてそれぞれ定性と定量を行つた. 2.Paper partition chromatographyは一次元上昇法で行い,移動相としては水飽和n-Butanol(1% ammonia)を用いた. 3, Counter current distributionでは,移動相として水飽和n-Butanol,固定相としてn-Butanol飽和水を用いた. 1回の分配では80回の振盪を行い,49回の分配を行つた. 4,以上の方法でEnsilage中のV.F.As.は比較的に容易かつ正確に定性と定量が出来た. 5, Ensilage中のAcetic acidは0.7～1.3%の間にあつて,原料の種類或は品質の善し悪しには関連がない.しかしながらButyric acidはEnsilageの品質が悪いもの程その含量が多かつた. Red cloverで造つたEnsilageには少量のPropionic acidが含まれていたが,玉蜀黍を原料としたものには含まれていなかつた

Quantitative estimation of the straight chain volatile fatty acids by the column Partition chromatography

In 1948 PETERSON and JOHNSON minutely described the column partition chromatographic method for the separation and quantitative estimation of the volatile fatty acids. In this experiment the partition chromatograms we employed were prepared as follows. The column was consisted of glass tube packed with silica gel, 30 cm in length and 8mm in diameter. Water was used as stational phase and benzene, 1.2% butanol benzene, 5% butanol chloroform, 12% butanol chloroform and butanol as mobile phase. Recoveries of formic, acetic, propionic and butyric acid were 104%, 101%, 99% and 100% respectively. We tried in vain to estimate the valeric acid in the presence of the acids previously described

ニワトリの神経におけるCholinesteraseの軸索内移動

1. The axoplasmic transport of cholinesterases was investigated in chicken vagus and sciatic nerve trunks by the ligature method. 2. Even 48 hours after ligation, the nerve segments in which the increased activity of acetylcholinesterase (AChE) was observed were ristricted within 5mm from the ligature. The activity of AChE in these segments increased linearly until 24 hours or 48 hours after ligation. 3. Two ligatures were made on sciatic nerve trunks and the change in activity of AChE between them was investigated. And it was found that only about 13% of AChE was moved by fast flow. The velocity was 233. 8mm/day in the anterograde and 97.7mm/day in the retrograde direction. 4. The activity of pseudo-cholinesterase (Ps-ChE) also accumulated with time at the proximal and distal side of the ligature

Studies on the Prevention of Leucocytozoon Infection of the Chicken. : VI. The Observation of the Gametocytes of Leucocytozoon caulleryi in the Unstained Wet Blood Film.

Usually the diagnosis of the infected chickens with leucocytozoon disease has been made by finding gametocyte of Leucocytozoon caulleryi in the blood smear stained by Giemsa's or May-Grunwald's method. But, as the inner part of the gametocyte can be observed in the unstained wet film of blood, the feature of the gametocyte considerably differs from that of the fixed sample. Method: One drop of blood from an affected chicken is placed on a cover-glass. This is inverted on a slide and the preparation is rimmed with paraffin. Then it is examined with phase-contrast microscopy at 37℃. Results and considerations: In macrogametocyte, the nucleus is rather small, usually have a curved or twisted rod shape and is suspended in protoplasm. The protoplasm is rich and filled with the immense number of fine granules. But in an usual smear sample, the nucleus shrinks and is covered with the granules at the time of smearing, and yet the granules are stained in dark purple by Giemsa's method, and hence it is considered that the shape of the nucleus is obscured. In microgametocyte, the nucleus is globular or oval, rather large in size compared with the size of the gametocyte itself, and placed at the nearly central point of the cell. The granules of protoplasm are a little larger in size and less in number than that of the macrogametocyte, and as the most of the granules are attached around the nucleus, these look like a pearl necklace in an optical section. As the nucleus expands at the time of smearing, it extends on nearly the whole surface of gametocyte and the protoplasm is seen indistinctly around it. As the granules are attached to the nucleus, they scatter on the surface of the nucleus as it expands. Most of the macro- and microgametocyte are covered with the membrane of the host cell. These cell membranes contain semifluid thinner than the protoplasm of the parasite. Some of which contain the granules of various sizes and they present the vivid Brownian motion. But these granules cannot be stained with Giemsa's dye

Studies on the Prevention of Leucocytozoon Infection of the Chicken : III. The Preventive Effect of Diaveridine.

1.diaveridineを飼料に最高0.01%から最低0.0001%までの各種の濃度になるように添加して,これを連続投与して本病の感染予防試験を行なった.その結果0.01%ならびに0.005%添加区においては感染が認められなかったが0.0025%以下の添加濃度では感染鶏が高率に認められた.従って本剤の最低有効濃度は一応0.005%の附近にあると思われる.しかしながら1964年度は,全国的に本病の予防剤としてpyrimethamineが発売されたため,岡山県下でも本病の発生が少なく,岡山大学農学部構内の鶏舎でも本病の感染率が一般に低かった.すなわち第1区の無添加対照区の感染率は35.0%であり,同時に行なった他の試験でも,薬剤無添加区での感染率は20～30%が普通であって,第1試験でみられたような濃厚感染は認められなかった.第2試験の0.001%添加区で81.3%の感染率を示したのはむしろ例外的現象と考えられる.従って第2試験の0.005%添加区がもしさらに濃厚な感染に曝された場合,果して完全に本病の感染を防ぎ得るか否かは疑問であるので,本剤を実地に応用する場合,最低有効濃度は0.005%より上にあると考えた方が安全と思われる.2.試験期間中における試験鶏の体重,産卵率,卵重等の推移を各区別の平均値で図示したように,いずれの場合も本剤がニワトリに対して毒性を示しているとは認められなかった.ただし第1図で,8月1日以後第3区および第4区の平均体重曲線が降下しているのは,第3区で2羽第4区で1羽がそれぞれ内臓型淋巴腫症に罹患し,体重が900gないし660gに減少したものが出たためであるが,8月29日現在の体重で,無添加対照区との間でF検定を行なっても5%の水準において有意の差は認められていない.第2図の平均産卵率の曲線についても,同様な傾向が見られるが,これも前記と同じ理由によるものと考えられ,期間中の総産卵個数について,対照区と各区の間でF検定を行なったが,いずれの場合も有意の差は認められなかった.3.ニワトリのcoccidium症に対するdiaveridineの効果は,前記の通りM. L. Clark3)によれば,sulfa剤と混じた場合0.001%であるといい,同じくpyrimethamineの効果は,S. B. Kendall&L. P. Joyner5)によると,sulfa剤と混合した場合0.004%が適当と認めている.従って,この両者はニワトリのcoccidiim症に対してはほぽ同等の効力を有しているものと見られるが,ニワトリのleucocytozoon病に対するpyrimethamineの最低有効濃度は著者ら2)の成績では0.00005%であるのに反し,diaveridineは前記の通り0.005%であるとすると,本病の予防効果では両者の間に100倍の開きが認められるわけであって興味深いことである.4.以上の試験により本剤単味の場合の最低有効濃度がほぼ0.005%であると判明したが,この濃度では実際の野外での応用の場合薬価の点で問題を生ずる恐れがある.したがってsulfa剤と混合投与した場合その相乗効果によりさらに投与濃度をさげる研究が行なわれないと本剤単味では応用範囲が限定されると考えられる

Studies on the Prevention of Leucocytozoon Infection of the Chicken. : V. The Leucocytozoon Infection in the Yearling Hen.

The investigations were carried out about the reinfection with leucocytozoon disease in yearling hens that were infected with this disease in the preceding year. From the investigations carried out in 1962, 1963 and 1964, the following results were obtained. 1. Among the 20 hens once infected with this parasite, the reinfection was not at all found in the same and the following years by the microscopic examination of blood smear sample made once every week. 2. Among the 22 yearling hens that were completely protected from leucocytozoon infection in the preceding year by the use of pyrimethamine or sulfadimethoxine, it was found by the blood examination that 11 hens (50%) were infected with this disease in the following year. 3. Eleven hens, in the blood of which no gametocyte had been detected in spite of the fact that they had been among the highly infected flock, were not at all infected in the following year. From the results mentioned above, we have come to the following conclusions. Hens recovered from natural infection of leucocytozoon disease acquire the strong immunity later. And the effect of pyrimethamine and sulfadimethoxine used in these experiments are quite perfect
