金沢大学環日本海域環境研究センター地球環境計測研究部門Spatial distributions of soil contamination by 137Cs (89 sampling points) and 239+240pu (76 points) near and within Dolon village were analyzed. An essential exponential decrease of contamination was found in Dolon village: the distance of a half reduction in contamination is about 0.87-1.25 km (in a northwest-southeast direction from the supposed centerline of the radioactive trace). This fact is in agreement with the available exposure rate measurements near Dolon (September 1949 archive data): on the basis of a few measurements the pattern of the trace was estimated to comprise a narrow 2 km corridor of maximum exposure rate. To compare computed external doses in air with local dose estimates by retrospective luminescence dosimetry (RLD) the gradient of radioactive soil contamination within the village was accounted for. The computed dose associated with the central axis of the trace was found to be equal to 2260 mGy (calculations based on archive exposure rate data). Local doses near the RLD sampling points (southeast of the village) were calculated to be in the range 466-780 mGy (averaged value: 645+/-70 mGy), which is comparable with RLD data (averaged value 460+/-92 mGy with range 380-618 mGy). A comparison of the computed mean dose in the settlement with dose estimates by ESR tooth enamel dosimetry makes it possible to estimate the "upper level" of the "shielding and behavior" factor in dose reduction for inhabitants of Dolon village which was found to be 0.28+/-0.068.

The local electronic state at every crystallographically independent molecular site was separately investigated in the organic superconductor alpha-(BEDT-TTF)(2)NH4Hg(SCN)(4) using site-selective C-13-NMR spectroscopy. The density of states (DOS) at three molecular sites shows independent temperature variation, which is caused by the long-range Coulomb interaction. Comparing the present results with those for a nonsuperconducting counterpart alpha-(BEDT-TTF)(2)RbHg(SCN)(4), we found that the uniform DOS at two of three independent molecular sites is crucial to induce superconductivity. Taking the site-dependent DOS as a parameter, we constructed a phase diagram for a superconductor with long-range Coulomb interaction, an alpha-type BEDT-TTF family, and summarized the competition between charge instability and superconductivity.

金沢大学理学部The structure of liquid Sn was studied by neutron scattering experiments in the widest temperature range that was ever performed. Though, on increasing temperature, the existence of the shoulder in the structure factor, S(Q), becomes less clear in the change of the overall shape of the S(Q), the structure related to this shoulder seems to be present even at 1873 K. The first-principle molecular-dynamics ~FPMD! simulation was performed for the first time for liquid Sn by using the cell size of 64 particles. The calculated results well reproduced S(Q) obtained by the neutron experiments. The angle distribution, g(3)(u ,rc), was evaluated for the angle between vectors from centered atom to other two atoms in spheres of cutoff radii rc's. The g(3)(u ,rc) shows that, with the decrease of rc from 0.4 to 0.3 nm, a rather sharp peak around 60 ° disappears and only a broad peak around 100 ° remains; the former peak may be derived from the feature of the closely packed structures and the latter one is close to the tetrahedral angle of 109 °. In addition, the coordination number, n, of liquid Sn counted within the sphere of rc50.3 nm is found to be 2–3 and does not change with the increase of temperature even up to 1873 K. These facts indicate that at least the fragment of the tetrahedral unit may be essentially kept even at 1873 K for liquid Sn. For comparison, the FPMD simulation was performed for the first time also for liquid Pb. No sign of the existence of the tetrahedral structure was observed for liquid Pb. Unfortunately, the self-diffusion coefficients, D's, obtained from this FPMD for liquid Sn do not agree with those obtained by the microgravity experiments though the structure factors, S(Q)'s, are well reproduced. To remove the limitation of the small cell size of the FPMD, the classical molecular-dynamics simulations with a cell size of 2197 particles were performed by incorporating the present experimental structural information of liquid Sn. Obtained D's are in good agreement with the microgravity data.

The anthropometric body measurements of 305 young female students were performed to obtain practical data of various body levels, width, thickness or circumferences, for apparel design. Correlationship between the obtained values and the body weight, body height, bust or waist was analysed and a tentitave classifications of somatotypes for apparel design was proposed by making use of the variance of the regression line for the body height and bust values of the subjects. Variation of bust values by respiration as well as the importance of under-wears were also discussed. The waist values were presumed to be as important as bust values. 14 typical body figures for the tentative somatotypes by means of the silhouettes were mentioned in Fig. 12. 1-12. 14.

Six patients with ear diseases caused by nose blowing are described. Four of them developed perilymphatic fistula.Exploratory tympanotomy was performed on the left ear of case 1 who complained of tinnitus. Leakage was identified in the area of the round window, which was covered with a piece of perichondrium. Three patients (cases 2-4) complained of tinnitus and a floating sensation, echo sound, and dizziness. All of them have the habit of nose blowing.The symptoms disappeared spontaneously after a rest.Two patients (cases 5 and 6) developed fullness of the ear after nose blowing. They were diagnosed as suffering from bullous myringitis. Nose blowing may predispose to formation of bubbles within an infected tympanic membrane.
