No full textShibako Mizuhane and "Sakaiko-Shuchiku-Kengi" are Japanese translations, first one was written by Johannes de Rijke, another was George Arnold Escher, who were employed Holland engineers. These books are preserved in the Mikuni Museum, "Ryu-Sho-Kan". These books consist difficult style concerning words. So they have not been opened to the public. The author already translated them to living, languages. In this study, the author especially investigates in the translation of living words from difficult foreign engineering words.departmental bulletin pape
Experimental Study on the stability of Sea-bed for the Flow into Rubble Mound (the last report) : Practical Design of the stability of Sea-bed for the Flow into Rubble Mound
No full textThe sea-bed ground of rubble mound in breakwater or revetment is scoured by waves. It brought many disasters, and has been written as serious problems. The author has been reported the many experiments by rubble mounds for practical design. This paper is the last report, the author proposes the practical design of the stability of sea-bed for flow into rubble mound.departmental bulletin pape
Comparative dynamics of potassium and radiocesium in soybean with different potassium application levels
No full textWe conducted a field experiment in soybean with different levels of K application to elucidate the comparative dynamics of 137Cs and K. The inventory of K in the shoots increased substantially from the fifth trifoliate stage to the full seed stage, and as the absorption of K increased, so too did the absorption of 137Cs. Overall, the effect of K application was much greater in terms of 137Cs dynamics than K dynamics or biomass production. K application reduced not only the accumulation of 137Cs in the shoots, but also the distribution of 137Cs to the grains. However, the decrease of 137Cs distribution to the grain had a much smaller effect on 137Cs accumulation in the grains than 137Cs absorption. A positive correlation was also observed between the exchangeable 137Cs/K ratio in the soil and the 137Cs/K ratio in the shoots for each growth stage, and the 137Cs/K ratios in the shoots at the full seed and full maturity stage were much higher than those at the fifth trifoliate and full bloom stage under the same exchangeable 137Cs/K ratio in the soil. These findings suggest a decrease in the discrimination of 137Cs from K during absorption after the full bloom stage. As a result of this and the increase in soil-exchangeable 137Cs/K with growth, radiocesium was more transferable to the shoots after the full bloom stage. Overall, these results suggest that lowering the soil-exchangeable radiocesium/potassium ratio after the full bloom stage by increasing K availability could efficiently reduce the transfer of radiocesium to the grains
Translation to Living Language from "Shibako Mizuhane" by Johannes de Rijke, a Holland Engineer on Government Employ
No full textShibako Mizuhane is the Japanese translation from the report of fascine spur and fascine mattress by Johannes de Rijke, a Holland engineer on Government employ. The Japanese tranlation is preserved in the Mikuni Museum, "Ryu-Sho-Kan". The contents of the book consist difficult style concerning construction technology of civil engineering. So it has not been opened to the public. In this study, the author translates it to living languages upon a position of civil engineering.departmental bulletin pape
Behavioural and pharmacological effects of fluvoxamine on decision-making in food patches and the inter-temporal choices of domestic chicks
No full textBehavioural effects of fluvoxamine (FLV, selective serotonin reuptake inhibitor) were examined in 1–2 week old domestic chicks. Chicks were tested in an I-shaped maze equipped with a feeder (ON feeder) that served 1 or 2 grains of millet at gradually increasing intervals, so that a depleting food patch was mimicked. By leaving the feeder, the food delivery program was reset, and chicks gained food at short intervals only after a travel to a dummy feeder (OFF feeder) placed on the opposite side of the maze. Chicks quickly learned to actively shuttle between the ON and the OFF feeders. FLV (intra-peritoneal injection, 20 mg/kg BW) acutely caused chicks to stay longer at the gradually depleting ON feeder. Inter-temporal choices were also tested, whereby two coloured beads were simultaneously presented, each associated with a small/short-delay reward or a large/long-delay alternative. FLV suppressed the choice of the short-delay option. It is suggested that an enhanced level of serotonin (5-HT) makes chicks more tolerant of the delayed food item in both behavioural paradigms. Furthermore, the decision to leave a depleting patch cannot be equated to choosing the long-delay option of the choice paradigm. Furthermore, FLV suppressed work efforts (velocity and running distance) in uncued shuttle and number of distress calls. In vivo microdialysis experiments revealed that FLV enhanced the extracellular concentration of 5-HT as well as dopamine (DA) locally in the medial striatum/nucleus accumbens. Underlying neuromodulatory mechanisms of behavioural control are examined in relation to locomotion, behavioural tolerance and interval timing
The extractability of potassium and radiocaesium in soils developed from granite and sedimentary rock in Fukushima, Japan
No full textPotassium (K) and radiocaesium (RCs) were chemically extracted from soils derived from granite (G soils) and sedimentary rock (S soils) in Fukushima, Japan. The extractants employed were 1 M HNO3, concentrated HNO3, and HF + HClO4. As S soils contain a lower amount of trioctahedral 2:1 phyllosilicates than G soils, the RCs/K ratio was higher in S soils than in G soils with 1 M HNO3 extraction, indicating that the potential risk of soil-to-plant transfer of RCs is higher in S soils than in G soils. In conclusion, information about surface geology is important in predicting the spatial pattern of soil characteristics related to transferability of RCs

No full textUnderstanding the anomalous thermoelectric behaviour of Fe-V-W-Al based thin films
No full textWe have investigated the thermoelectric and thermal behaviour of Fe-V-W-Al
based thin films prepared using radio frequency magnetron sputtering technique
at different base pressures (0.1 ~ 1.0 X 10-2 Pa) and on different substrates
(n, p and undoped Si). Interestingly, at lower base pressure, formation of bcc
type of Heusler structure was observed in deposited samples, whereas at higher
base pressure, we have noted the development of non-Heusler amorphous structure
in these samples. Our findings indicates that the moderately oxidized Fe-V-W-Al
amorphous thin film deposited on n-Si substrate, possesses large magnitude of
absoulte S ~ 1098 microvolt per kelvin near room temperature, which is almost
the double the previously reported value for thin films. Additionally, the
power factor indicated enormously large values ~ 33.9 milliwatt per meter per
kelvin sqaure near 320 K. The thermal conductivity of the amorphous thin film
is also found to be 2.75 watt per meter per kelvin, which is quite lower
compared to bulk alloys. As a result, the maximum figure of merit is estimated
to be extremely high i.e. ~ 3.9 near 320 K, which is among one of the highest
reported values so far. The anomalously large value of Seebeck coefficient and
power factor has been ascribed to formation of amorphous structure and
composite effect of thin film and substrate
