Suppression of Wind-Induced Vibration of Tower-Shaped Structures by Dynamic Dampers
Autor: Ryoji Nakagaki, Toshio Ueda, Kazuo Koshida
Publikováno v: Structural Engineering International. 3:50-53
Many flexible tower-shaped structures experience aerodynamic problems under natural wind action. Dynamic dampers can serve as countermeasures for wind-induced oscillation. In this paper, three type...

Synthesis of Ethylene Oxide Adducts of s-Alcohols
Autor: Naoji Kurata, Takakiyo Goto, Toshihiro Fujii, Kazuo Koshida
Publikováno v: Journal of Japan Oil Chemists' Society. 42:118-125
Using the s-alcohols having a carbon range C12C14 prepared from available technical paraffins (C12C14), a technically effective synthetic method for obtaining highly purified s-alkyltri (oxyethylene) ethers using a BF3 catalyst was developed.To prepa

Biodegradation of Surfactants in River Water and Their Toxicity to Fish
Autor: Toshihiro Fujii, Kazuo Koshida, Naoji Kurata
Publikováno v: Journal of Japan Oil Chemists' Society. 26:115-118
The tests for acute toxicity to fish were carried out on nine commercial surfactants of various chemical structures including secondary alcohol derivatives. The tests were extended to study the toxicity of biodegradation intermediates of some surfact

Biodegradability of Nonionic Surfactants in River Die-away Test using Tama River Water
Autor: Naoji Kurata, Kazuo Koshida
Publikováno v: Journal of Japan Oil Chemists' Society. 24:879-881
A testing method for biodegradability of nonionic surfactant has recently been legislated by Japanese Industrial Standards Committee. As the method is, however, concerned only with the disappearance of surface activities, a comparison of results of s

Biodegradability of sec.-Alcohol Ethoxylate
Autor: Kazuo Koshida, Naoji Kurata
Publikováno v: Journal of Japan Oil Chemists' Society. 25:499-500
The biodegradability of secondary alcohol ethoxylate has been already proved by various test methods. This paper is provided to show that secondary alcohol ethoxylate is by far easily degradable than nonylphenol ethoxylate in continuous-flow activate
