抄録 In order to stady the relation between the mottled tooth, struma and fluorine content of drinking water, the author investigated the teeth and thyroid glands of school-boys and girls living in Yoshioka Hot Spring and its vicinity, Tottori Plefectue. Yoshioka Hot Spring is a simple thermal with high fluorine content (max. 5mg. per liter). The incidence of the mottled tooth was 51.5 per cent in average. A close relationship was observed between the morbidity of the mottled tooth and high fluorine content of drinking water. But the author noticed also the occurrence of the mottled tooth among the school-children living in the regions where the fluorine content of drinking water proved to be even less than o.1ppm., and the author emphasizes the possibility of the causal factors other tham fluoline. The palpability of thyroid gland was 78.4 per cent in average, but no significant relation was recognized between the struma and fluorine. Between the mottled tooth and struma, no relation was proved as significant, too.

抄録 The membrane potential difference with the living human skin between the physiological saline and the mineral waters was measured. The hypotonic mineral waters, that have a pH higher than the isoelectric point of human epidermis, showed a positive potential against the physiological saline. The membrane potential difference of these mineral waters against the physiological saline at the same temperature tends to increase by raising the water temperature. The acid waters showed either a positive or a negative potential against the physiological saline. The membrane potential difference between the mineral wates at room temperature and at the temperature raised above it is increased according to their temperature difference,

著者 小野田 進|
抄録 The author investigated the changes in skin temperature, oral temperature, blood pressure, pulse rate, respiration rate and weight of body before and after a radio-active thermal bath in Misaswa, and compared the results with the corresponding changes after a plain water bath at a same temperature (43℃) with same duration (5min.). A rise in skin temperature after the thermal bath durated longer than after the control plain water bath. Changes in oral temperature did not correspond to the changes in skin temperature and to the suhjective warm feeling. Changes in the pulse pressure showed no significant difference between the radio-active thermal bath and plain water hath. But a more prolonged lowering of the minimal blood pressure was proved after a radio-active thermal bath than after a plain water bath at same temperature with same duration. The response in blood pressure to thermal bath was more marked in winter than in summer. A rise in pulse rate was recognized after all kinds of hot baths, but no difference was proved between them. A slight acceleration of respiration rate and a loss in weight were observed after hot bath at 43℃ for 5 minutes. But these effects were slighter after radio-active thermal bath than after plain water bath at same temperature and same duration.

抄録 Many hydraulic structures are damaged by under flood flow and storm waves year after year. Many cases of dike and breakwater failure are caused by the suck out of sand from behind the revetment. This type of failure will be in close relation to the dynamic behavior of sand bed around the revetment. In this paper, from this point of view, we investigated the basic characteristics of such sand movement by small model tests and tried to explain the hydro- and soil-mechanical mechanism of this phenomenon theoretically.

抄録 The numerical feasibility of determining soil water retention and hydraulic conductivity functions simultaneously from one-dimensional transient flow experiments in the laboratory by parameter estimation method is evaluated. Soil hydraulic properties are assumed to be represented by van Genuchten's closed-form expressions involving two unknown parameters: coefficients α and n . These parameters are evaluated by nonlinear least-squares fitting of predicted and observed pressure head with time. Gravity drainage experiments are performed for Toyoura standard sand to evaluate the adequacy of this proposed method.

抄録 A technique for determining the layer structure and content of clay minerals was developed based on the relationship between temperature, and moisture characteristics of clay minerals. Moisture content in standard specimens, prepared by mixing montmorillonite, kaolinite and quartz in various proportions, was determined by measuring weight loss after heating. Based on the results from differential thermal analysis tests, the ignition loss method was found to be widely applicable to clays with montmorillonite and kaolinite as the main components. Dehydration of constituent water occurred at 530℃ and 800℃ in two- and three-layered clay minerals, respectively.

抄録 Lake Biwa is the largest lake in Japan, and one of the most important fresh water resources. The Hino River is the fourth largest river among the rivers which flow into Lake Biwa. The eutrophication of the lake has been warned since the 1960s. In order to improve the water quality of the lake, to decrease the loads through rivers is inevitable. Therefore, it is needed to predict the effects of measures to control pollutant loads and the influence of development in the basin on the loads from rivers before developing the basin and taking measures. This paper deals mainly with the model of water quality management for the Hino River and the effects of the development in the basin on the water quality. The model was formulated considering loads from forests, rice paddy fields, households, housing land, industrial factories. Using this model, a calculation system by a microcomputer was developed and the influence of urbanization of the basin was discussed.

抄録 Practical utilization of ram type electrical discharge machining in uninflammable fluid has been expected in place of inflammable kerosine type fluid for unmanned operation in a workshop. The electrical discharge machining performance in deionized water is experimentally investigated on the basis of the analysis of the crater generated by a single pulse discharge. The experimental analysis makes it clear that the electrical discharge machining performance in deionized water is greatly affected by the electrode polarity. The metal removal rate in the normal polarity machining is higher than that in reverse polarity machining, while the electrode wear rate in the normal polarity machining is greater than that in reverse polarity machining. Therefore the electrode polarity should be properly selected according to the purpose of machining.

抄録 Transient characteristics of the rectangular latent heat storage vessel packed with shape-stabilized phase change (solid-liquid) material (PCM) are investigated numerically by solving the governing equations of both the PCM and the heat transfer medium(water) simultaneously as a conjugate problem with the finite difference technique. It's found that the heat storage characteristics are greatly affected by the flow direction of the heat transfer medium since the natural and forced convection coexists in the heat storage vessel. That is, it is classified that the effectively thermal efficiency of the latent heat storage system is obtained by the downflow along vertical PCM for heat storage process and the upflow for heat release process. The effect of the inlet velocity of heat transfer medium(water) on transient heat characteristics of the latent heat storage system is also revealed in the present study.

抄録 A monoacylglycerol lipase (MGL) was purified from Pseudomonas sp. LP7315 by ammonium sulfate precipitation, anion-exchange chromatography, and preparative electrophoresis. The purified enzyme was homogeneous on an SDS-polyacrylamide gel with a molecular mass of 59 kDa. Its hydrolytic activity was confirmed to be specific for monoglycerides: the enzyme did not hydrolyze diand triglycerides. MGL was found to be stable even after l-h incubation at 65℃. The hydrolytic activity depended not only on temperature and pH but also on the type of monoglyceride used. MGL also catalyzed monoglyceride synthesis at 65℃ in a solvent-free two-phase system, in which fatty acid droplets were dispersed in the glycerol phase with a low water content. The synthetic reaction proceeded at a constant rate for approximately 24 h and reached an equilibrium after 48 h of reaction. The initial rate of the synthetic reaction depended on several factors: the type of fatty acid used as the substrate, the amounts of fatty acid and glycerol, and the concentration of MGL in the glycerol phase. To analyze the effects of these factors, a kinetic model was developed based on the assumption that the adsorption equilibrium of MGL molecules at the interface between the two phases is the rate-determining factor for the synthetic reaction. The model was found to yield a good approximation of the initial synthetic rate under various reaction conditions. The analysis suggests that the adsorption behavior of MGL onto the interface had a large effect on the initial rate of the monoglyceride synthesis.
