The Co-Cr alloys which have an excellent mechanical property and corrosion resistance are known as one of the most important metallic biomaterials. In this study, the electrochemical behavior of Co-Cr alloy in deaerated different electrolytes was investigated by using polarization curve measurements. Ti and stainless steels (Type 316) were used as a comparing material. The Co-Cr alloy has high corrosion resistance compared with the stainless steel in NaCl solution. The current increasing with the pitting corrosion was appeared in polarization curves of stainless steels. But it was disappeared in polarization curves of Co-Cr alloy. The passive state of the Co-Cr alloys was kept even in the pitting region of the case of stainless steels. The passive film on the Co-Cr alloy is stable as same as the film on Ti. According to the polarization behavior, the Co-Cr alloys are expected to use as the biomaterials.
Distribution of Fluorescent Whitening Agents as an Indicator of Domestic Wastewater

The distributions of fluorescent whitening agents (FWA) in the water of the Yasu River and their tributaries flowing into Lake Biwa (Japan) were surveyed on winter and summer. The FWA fluxes had linear correlation with the corrected resident population in catchments of the tributaries of Yasu River. Therefore, the FWAs in the rivers come from domestic wastewater, and those fluxes in the tributaries depended on the human population of their catchments. As an application of the FWA indicating domestic wastewater, we could assess seasonal changes in the sources of dissolved organic matter in the tributaries.
Variation in the Size of Light Harvesting 1 of Purple Bacteria
Akiyama, Machiko,Nagashima, Kenji V.P.,Inoue, Ryouji,Wakayama, Tatsuki,Kise, Hideo,Hara, Masayuki,Kobayashi, Masami Korean Society of Photoscience 2002 Journal of Photosciences Vol.9 No.2
We examined the bacteriochlorophyill/bacteriopheophytin ratios in several species of purple bacteria containing only LHI. The pigment ratios depended greatly on species. Further, Rhodospirillum rubrum showed wide variation when grown under different light intensity, and Rhodobium marinum showed significant variation from culture to culture even under the same light conditions. The protein ratios of a/RC and $\beta$/RC estimated by SDS-PAGE of chromatophores of Rsp. rubrum and Rbi. marinum exhibited the ratio of $\beta$/$\alpha$ > 1. These findings gave us the novel idea that there are two types of LHl; one is a C-shaped open antenna composed by $\alpha$$\beta$ units surrounding a RC, and another is a small closed ring antenna composed by $\alpha$$\beta$ units located peripherally in a variable ratio to the core complex like LH2.
