The paper examines how well standard sources of impact sounds(bang-machine, A-ball, NF-ball, new rubber ball)imitate real impact sounds(human jumping and hopping).The compared sounds were described from psychoacoustic point of view.At the same time similarities between the impact sounds were judged in the psychoacoustic experiment.Results were compared with the existing standards expressed in F- and S-maximum sound levels:L_{A max, F}, L_{A max, S} and sound exposure level L_AE.

We screened the differentiation-inducing activities of 39 mushroom extracts from Akita prefecture, Japan, on the mouse osteoblastic cell line, MC3T3-1. Sixteen phosphate buffered saline (PBS), 8 boiled PBS, 14 ethanol and 12 methanol extracts induced alkaline phosphatase (ALP) activities, an indicator of MC3T3-1 cell differentiation. The enzyme activities were markedly induced by extracts of Tricholoma auratum, and we isolated the active compound from methanol extracts of this mushroom. Physical data for the isolated active compound were identical to those for (,24R)-ergosta-,-diene-3β,,6β-triol (1). 1 induced ALP activities of MC3T3-1 cells and promoted cell proliferation. To investigate the relationships between the chemical structure and differentiation-inducing activity of the compound, ALP-inducing activities of MC3T3-1 cells by 1, ergosterol (2), ergocalciferol (3), cholesta-3β,,6β-triol (4), -dehydrocholesterol () and cholecalciferol (6) were tested. The enzyme activities of MC3T3-1 cells were increased 3.0-fold by 10 μM 1 and 2.4-fold by 10 μM 4. However, 2, 3, and 6 did not induce MC3T3-1 cell ALP activity at 0.1—10 μM. These results suggested that the OH groups at C- and/or C-6 of 1 and 4 played an important role in their differentiation-inducing activities on MC3T3-1 cells. Furthermore, 1 suppressed induction of MC3T3-1 cell apoptosis by serum starvation.

There has been strong demand for enhancement techniques of single-phase forced convection heat transfer because of its wide area of application on the one side and because of inferior heat-transfer capability, when compared with phase change heat transfer such as boiling and condensation, on the other side. The enhancement techniques are indispensable when gases are used as heat-transfer media. In this article the basic principles of enhancement of single-phase forced convection heat transfer are described in the first place. Three principal techniques currently employed, i..,(a) interrupted fins, () twisted tapes, and (c) turbulence promoters, are introduced. Mechanisms of heat-tansfer enhancement and the state-of-the art review on the R&D are presented for these techniques. In addition to these, supplementary remarks are given on techniques utilizing multiphase flow and electrostatic field.

帯状疱疹に対するRo-8181の有効性, 安全性および有用性を検討するため, ヒト血清アルブミンを対照薬として, 二重盲検比較試験を行つた。皮膚症状の観察項目別の改善率では, 水疱·膿疱において投与開始後日目でRo-8181群70%, placebo群50%で, 両群間に差(p<0.05)が認められた。皮膚症状改善度の推移を著明改善以上の症例についてみると, 投与開始後4日目の著明改善率はRo-8181群8%, placebo群0%であり, Fisherの直接計算法で両群間に差(p<0.05)が認められた。また, 投与開始後日目の著明改善率はRo-8181群15%, placebo群3%であり, κ² 検定で両群間に差(p<0.05)が認められた。主治医による有効性の判定ではU検定でRo-8181群が優れている傾向が認められた。主治医による安全性の判定では副作用発現率がRo-8181群83%, placebo群14%であり, U検定で両群間に差(p<0.001)が認められた。主治医による有用性の判定ではU検定で両群間に差は認められなかつた。以上の結果より, 帯状疱疹に対し, Ro-8181は皮疹のうち水疱·膿疱に対して有効であり, 主治医判定でも有効性が認められたが, 安全性については本薬剤の耐薬性が示されたものの副作用の発現率が高かつたため, 有用性は高くないと考えられた。

In the first part of the present work the interaction of glycophorin with dimyristoylphosphatidylcholine (DMPC) is studied by freeze fracture electron microscopy, densitometry, calorimetry, and 90° static light scattering. An exothermic lipid/protein interaction energy of W_P=190 kJ•mol^-1 was found by application of the well known Van Laar relation for the displacement of the freezing point and the Gibbs-Duhem relationship. Secondly, the effects of Ca²⁺ on the lipid/protein interaction were studied. Following Ca²⁺ addition a remarkable decoupling of the interaction of the glycophorin head group with the bilayer surface was revealed by densitometry and gold-labeling electron microscopy. It is estimated that about 80% of lipid once disturbed by the adsorption of glycophorin head groups is decoupled after addition of Ca²⁺. Thirdly, the selective interaction of glycophorin with binary lipid mixtures was studied, including the mixtures of DMPC with dimyristoylphosphatidylserine (DMPS) and dilauroylphosphatidylcholine (DLPC), and the mixture of dipalmitoylphosphatidylcholine (DPPC) with DLPC.

We have discussed the resolution of submicron photoluminescence (PL) imaging using a solid immersion lens (SIL), which collects an evanescent light field. We apply the SIL microscope to measure PL image of a strip-line-patterned GaAs quantum well structure at low temperature. An improved resolution beyond diffraction limit and high collection efficiency of PL are realized.

The gamma-ray spectrum and the conversion-electron spectrum are measured in the decay of the Tb¹⁵² activity. The L-subshell electron lines of the 586. keV +→2₁⁺ transition are separated by the ion-free beta-ray spectrometer. The M1-2 mixing ratio, δ², and the dimensionless ratio X of 0-2 mixing of the 586. keV transition are obtained to be δ²≤0.16 and 0.034≤X≤0.038, respectively. The 2 branching ratio (2; +→0_g⁺): (2; +→2₁⁺): (2; +→0₁⁺) is determined to be 0.023 : 1.0 : .6.

Intracerebral injection of vegetative myxamoebae of strains of Polysphondylium pallidum caused 80 to 100% mortality in mice, whereas a 30 to 50% mortality occurred with strains of Dictyostelium giganteum and D. mucoroides. Death is attributable to an unidentified toxic factor. Histopathologically a giant cell formation was seen in the spleen of mice. This cell was different from Langerhan's or foreign body giant cell. Rats injected intracerebrally behaved similarly. Intranasal instillation of myxamoebae in guinea pigs caused transient pneumonia. Myxamoebae do not multiply in the brain tissues of mice or rats, or in the lungs of guinea pigs.
Intranasal instillation of vegetative myxamoebae is less pathogenic than free living amoebae like Hartmanella culbertsoni, H. rhysodes, Naegleria sp. (Culbertson strain HB-1), or Naegleria aerobia.

The doping of a two-orbital chain with mobile S=1/2 fermions and strong Hund's rule couplings stabilizing the S=1 spins strongly depends on the presence of a level difference among these orbitals. Using density matrix renormalization group (DMRG) methods, we find a finite spin gap upon doping and dominant pairing correlations without level difference, whereas the presence of a level difference leads to dominant charge density wave (CDW) correlations with gapless spin-excitations. The string correlation function also shows qualitative differences between the two models.

A disconnection transition is aphase transition which accompanies a change in the connectedness ofthe fermi sea. The existence of such a transition is established in thecontext of a one-dimensional interacting model. The model considered is an extension of the deltafunction bose gas in which its fourth order conservation law is addedto the original hamiltonian. For low density, the ground state of themodel consists of two separated fermi seas and there are two distinctbranches of excitations. At a critical density, one branch ofexcitations disappears, and there is a second order phase transition toa single fermi sea ground state.

We have performed a large scale quantum Monte Carlo study of the quantum phase transition in a planar spin-1/2 Heisenberg antiferromagnet with CaV₄O₉ structure. We obtain a dynamical exponent z=1.018±0.02, consistent with Lorentz invariance. The critical exponents β, ν and η agree within our errors with the classical 3D O(3) exponents, expected from mapping to the nonlinear sigma model.

We report the current-voltage characteristics of a single-electron circuit, in which the Coulomb island of a single-electron transistor is connected to the source electrode of another transistor.The Josephson-like current of one of the transistors was tuned by adjusting the gate voltage of the other, reflecting the uncertainty relation between the phase difference and the particle number. We found that the “parity effect” or “even-odd asymmetry” was also affected by the gate voltage of the other transistor. A possible explanation for this asymmetry-tuning is presented.
