Japanese Economic Activities in Nansha Islands in the Early 20th Century : Concentrating on the Rasa Island Phosphate Ore, Ltd

In the Meiji era, the Japanese rushed into the Pacific Ocean islands for the sake of economic resources. The initiative has expanded to South China Sea in the end of Taisho period. The Rasa Island Phosphate a limited Partnership was founded by agriculture Dr. Noritaka Tsunetō. The Rasa Island Phosphate Ore, Ltd advanced to the Nansha Islands to mine mineral phosphate. The economic activities of the Rasa Island Phosphate Ore, Ltd lasted for eight years. Because of the economic downturn, they withdrew from the islands. The economic activities of the Rasa Island Phosphate Ore, Ltd was an example of the Japanese development in South China Sea, which unlike the national policy companies of the 1930s. It presents a side of Japan\u27s economic southward development.文部科学省グローバルCOEプログラム 関西大学文化交渉学教育研究拠点[東アジアの思想と構造

Numerical and experimental study of a warming up effect of an underexpanded rarefied rf plasma jet outflowing into a flooded area

© Published under licence by IOP Publishing Ltd.A mathematical model of the rf plasma flow at 13.3-133 Pa in transition regime at Knudsen number values 8 × 10-3 ≤ Kn ≤ 7 × 10-2 and the nozzle pressure ratio n = 10 for the carrier gas is described. The model based on both the statistical approach to the neutral component of the rf plasma and the approach to the continuum model for electron and ion components. The results of plasma flow calculations performed both for an undisturbed flow and for the stream with a sample at a prescribed electric field are described. The effect of a warming up of a stream in a mixture zone confirmed by comparison of numerical results with experimental ones is found

The influence of RF plasma treatment at low pressure on the permeability of a polyurethane nanocomposite

The statistical model of treatment of a polyurethane nanocomposite by low-energy ionic streams in RF plasma at pressure in the range 13.3-133 Pa is developed. The dependence of the permeability of a filled nanocomposite on the filler mass fraction, both before and after RF plasma treatment, is theoretically investigated. © 2014 Allerton Press, Inc
