On Local Symmetric Order Parameters of Vortex Lattice States

This paper gives a new refined definition of local symmetric order parameters (OPs)(s-wave, d-wave and p-wave order parameters) of vortex lattice states for singlet superconductivity. s-wave, d-wave and p-wave OPs at a site (m,n) are defined as A, B and E representations of the four fold rotation C_4 at the site (m,n) of nearest neighbor OPs etc. The new OPs have a well defined nature such that an OP(e.g. d-wave) at the site obtained under translation by a lattice vector (of the vortex lattice) from a site (m,n) is expressed by the corresponding OP (e.g. d-wave) at the site (m,n) times a phase factor. The winding numbers of s-wave and d-wave OPs are given.Comment: RevTeX v3.1, 5 pages with 3 figures, uses epsf.sty. to appear in Prog. Theor. Phys. Vol.101 No.3. (1999

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

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
