抄録 This paper presents a method using simulated annealing(SA) and genetic algorithm(GA) to solve the plant layout problem in which the layout is evaluated by material handling cost and maintainability. In the former study about facility layout problem, it was either the minimization of the objeective function consisting of transport cost or the maximization of the objective function consisting of closeness rating. In this paper, both transport cost and maintainability were included in the objective function to be minimized. The plant layout problem, this paper proposes the heuristic procedures to obtain a suboptimal layout solution by combining SA with GA. From the simulation by computer, it concluded that the method which SA is combined with GA is more efficient than the method which utilizes SA and GA independently.

抄録 The author proved that consumption of iodate by proteinfree serum filtrate, an index of total reductive substance in serum filtrate, was increased after a radioactive thermal bath of Misasa (400-700×10(-10) Curie units Rn per liter), at a temperature of 40°~45℃ for five minutes. Reduced glutathion in blood showed little change, but oxidized and total glutathion tend to rise and decreased only temporarily. Reduced ascorbic acid in blood and urine increased after the radioactive thermal bath, but the oxidized and total ascorbic acid decreased after a temporal increase. After the thermal. bath a tendency of fall in reduced and oxidized ascorbic acid content was observed in liver, lung, and adrenal glands, and a tendency of rise was shown in kidney, spleen, skin and musclein albino rats. By a series of daily successive thermal baths a fall in ascorbic acid content was observed in most of the organs examined in the first week (on the fourth day) and then a reactive increase was shown during the second week.

抄録 The thermal expansion coefficient of some bioactive glasses in the system CaO-SiO(2)-B(2)O(3) were adjusted to be similar to that of titanium by controlling the composition. A glass of composition 45CaO・30SiO(2)・25B(2)O(3) was selected among those as the enameling glass. A slurry was prepared by mixing the glass powder and ethanal to be developed on titanium and heated at 740℃ for 30 min. Thus treated specimen was soaked in a simulated body fluid (Kokubo solutiion). FT-IR reflection and thin film X-ray diffraction analyses indicated apatite formation on the glass coating layer within 12 h of soaking in the fluid. Thus titanium could be provided with bioactivity due to the enameling.

抄録 After the internal use of daily 3 grams of crude chondroitin sulfate cholinesterase activity of serum decreased and elimination of glycuronic acid in urine increased, but no definite change in serum mucoprotein level was observed. Mucoprotein in serum showed a positive linear correlation to erythrocyte sedimentation rate, and chondroitin sulfate promoted the e.s.r. in vitro and in vivo. Chondroitin sulfate showed no marked influence on phagocytosis of human leucocytes in vitro, but it promoted the production of agglutinin in rabbits by subcutaneous injection.

抄録 Nb(2)O(5)-and Ta(2)O(5)-doped calcium si1icate glasses were soaked for various periods in a simulated body fluid(Kokubo solution) up to 30 days. Apatite formation ability of the surface of these glasses were investigated with thin-film X-ray diffraction and FT-IR reflection spectroscopy. The effects of these additive oxides on the bioactivity of CaO・SiO(2) based glass were discussed. A small amount of Nb(2)O(5) and Ta(2)O(5) suppressed the rate of silica hydrogel layer formation and the apatite formation on the surface of the glasses. The rate of the apatite nucleation on the surface of Nb(2)O(5)-doped calcium silicate glass was slower than that on the surface of Ta(2)O(5)-doped calcium silicate glass. It was concluded that the decrease in the apatite forming ability of calcium silicate glasses by these additive oxides is attributed to the suppression of formation of silica hydrogel layer which plays an important role in apatite nucleation.

タイトル(別表記) CHEMICAL STUDIES ON MISASA HOT SPRING (18) A PYRITE-POLYSULFIDE THEORY OF SULFUR SPRING
フルテキストURL 007_015_019.pdf
著者 芦沢 峻|
抄録 In Misasa there occur only few weak sulfur springs, their maximum hydrogen sulfide content being about 5mg per liter. The ground of Misasa consists of granite and there is no active volcano in the vicinity. So the author tried to explain the mechanism of the occurrence of sulfur spring in Misasa by a reaction of the primarily alkaline thermal water upon pyrite. Namely: XFeS(2) + 3Na(2)C(O)3 = 2Na(2)S(1-5) + Na(2)S(2)O(3) + 3CO(2) + XFeS(1-2) Thiosulfate in sulfur spring waters should not be taken for a secondary product from hydrogen sulfide as accepted generally, but is most probably a primary product to the latter. The phenomenon of white turbidity in sulfur spring is caused mainly by the sulfur liberated from the polysulfide decomposed by the change in pH and temperture of thermal waters and not by the sulfur liberated from the oxidation of hydrogen sulfide. Some experimental data were shown to support the theory.

抄録 Knee replacement arthroplasty is indicated for the patient with advanced knee pain, knee deformation, and knee functional disorder. The aim of this study was to estimate loosening after a knee replacement arthroplasty. Loosening is measured by a frequency response function, and mobility by random vibration. The modal parameters for the knee joint are obtained by applying a modal analysis to the frequency response function. The values decrease as the knee joint prosthesis loosened. These parameters serve as an index for the condition between a thighbone and the prosthesis. The various indexes will greatly clarify the stage of advance in the loosening of knee-joint prostheses.

抄録 In evaluating the stiffness of skin surface, internal structures such as bone and muscle often affect the measurements. In the present paper, acoustic random vibration is used to estimated the viscoelasticity of a silicone-gel model. This viscoelasticity, which includes two different stiffness strata, is first estimated using a mechanical impedance spectrum, which describes the relation between the depth and viscoelasticity of internal objects. This method is applied to the depth of a silicone-gel tumor model measured by ultrasound imaging and the viscoelasticity of internal gel can be accurately estimated.

抄録 The fluorine content of 67 samples of mineral waters in Misasa, Asozu, Togo, Hamamura, and Iwai Hot Springs was investigated by Zirconium-Alizarine Sulfonate method. It ranged from 1.5 to 15 mg. per liter, 3-6mg. per liter in the majority. Most of the river and well waters in the same districts contained no measurable amount of fluorifle. In Misasa, Asozu, Togo and Hamamura Hot Springs 68-83 per cent of the schoolchildren who take thermal waters habitually as drinking water suffer from mottled tooth. On the contrary 2-10 per cent of the schoolchildren who do not drink thermal waters habitually showed mottled tooth. In Iwai no inhabitant uses thermal water as drinking water, so that the incidence of mottled tooth among them was only 2.8 per cent. Concerning the incidence of struma in the schoolchildren no relationship was proved between the occurrence of mottled tooth or fluorine content of thermal waters.

抄録 Fine particles of Ti-V alloy were prepared by means of arc method and were investigated on internal structure and phase transformation using HR-TEM and EDS. Martensite phase was observed in a particle containing comparatively low concentration of V, and ω phase was also found to exist in a nearly 15% V particle. The structure of the ω phase in the fine particle is remarkably expanded in comparison with the bulk sample, and the ω phase is unstable, so that it has disappeared in a few seconds during TEM observation.

抄録 The microstructure of oxidizing magnesium at elevated temperatures has been studied using HR-TEM, SEM and EDS. Two kinds of thin magnesium specimen for TEM observation were prepared. One was oxidized after preparing TEM foil of magnesium, the other was prepared from an oxidized bulk magnesium for observing the cross-section of oxide/Mg interfacial region. In the former, several oxides(MgO) morphologies were observed depending on the temperature and time of the oxidization. The growth of needle-like oxides formed at 573K and mottled oxides formed at 773K were recognized as a remarkable phenomenon belonging to the local oxidization. These oxides were composed of poly-crystal. The thin uniform oxidization layer was also observed in all conditions. In the cross-sectional observation, the local oxide layer, nearly 300nm in thickness, on the matrix(Mg) were observed. The thin uniform oxidized layer of bulk samples was identified as a kind of modified layer (~40nm in thickness) in which the formation of HR-TEM lattice fringes were prevented by the strain due to the slight oxidization.

抄録 At Sekigane Hot-Spring, Tottori, Japan, where three hot-springs place side by side, the auther measured the variation of spring temperature, pH, Cl,- HCO(3)- and SO (4)-- content and the amount of flow, during and after, pumping suction of one hot-spring. About the variation of other hot-spring, immediately after the commencement of suction, the content of HCO(3)- decreased and that of Cl- and SO(4)-- increased. Then the increase of HCO(3)- content and the decrease of Cl- and SO(4)--contents appeared with the lapse of time. After stopping the suction, these changes in contents were reversed agaln, that is, the decrease of HCO(3)- and the increage of Cl- and SO(4)-- were observed. Immediately after the second suction was begun, HCO(3)- increased and Cl- and SO(4)-- decreased rapidly. The amount of flow increased only when the pumping suction stopped. At the hot-spring which was pumped, HCO(3)- and SO(4)-- contents decreased and the slight increase was observed in Cl- content. Of cource, only when the suction stopped, the amount of flow decreased. But at these hot-springs, the ratio of Cl-/SO(4)-- has always constant value, about 1.05. These results show that these three hot-springs belong to the same line and difference was observed only in the contamination with ground-watres.

抄録 In this study we investigated the water quality of surface runoff and groundwater runoff from the basins of the Yodo River and the Asahi River based on that separated by a numerical filter. The water quality of the surface runoff is greatly different from the groundwater runoff. The tendency of concentration change in accordance with river discharges is different from each other. The water qtiality of groundwater runoff changes with river discharges clockwise in many cases. The differences of COD and SS originating from those of population and industrial activities in each basin are found in the lower SS concentrations of the surface runoff and the COD cencentrations of the groundwater runoff. The nutrients and chlorine ion were investigated, too.

抄録 Scribing of copper coated alumina ceramic board with Q-switched YAG laser used for the maskless direct patterning of circuit board is experimentally investigated, which leads to efficient production of trial circuit board. Better dividing of alumina circuit board 655μm in thickness can be attained by the scribing of about 100μm depth. Higher repetition frequency of laser irradiation leads to smaller notch angle and lower breaking load.

抄録 Using Na(2)SO(4) labelled with S(35) transition of sulfate ion into the body across the skin was investigated soon after the bath in sodium sulfate solution at varying conditions. Mice were used as test animal. Percutaneous absorption of sulfate ion proved to be promoted at high bath temperature (45℃) than at indifferent temperature(37℃). stronger by the bath of longer duration (30min.) than by the bath of shorter duration (10min.), increased after repeated baths than after a single bath. It was accelerated by making a burn to the skin of the bathed animals. Layton and Dziewiatkowski proved that the parenterally administered sulfate ion was partly fixed in the connective tissue as chondroitin sulfate. The author had proved that chondroitin sulfate relieves pain, increases peripheral circulation and when administered parenterally promotes production of immune bodies. In Japan natural and artificial Glauber's salt spring bath are known to have a beneficial effect on wound healing, but no satisfactory explanation was given till today. Lith reported that a hypertonic solution of sodium sulfate promoten wound cure by external application and Seki showed that subcutaneous connective tissue of mice was stimulated by the bath in sodium sulfate spring. And so the abovementioned author's data seem to throw some light on solving the problem.
