Electric rocket engines (electric thruster), in which electric energy is converted to kinetic one, are suitable for future long missions in space because they can achieve higher specific impulse, i.e., higher propellant serving than conventional chemical thrusters. At Osaka Institute of Technology (OIT), several kinds of electric thruster, that is, magneto-plasma-dynamic (MPD) thruster, direct-current...
Measurements and observations of juvenile hatchery-reared three-lined tonguefish Cynoglossus abbreviatus were performed to examine morphological abnormalities, focusing on five asymmetric characters: eye position, body coloration, presence of a nasal tube, presence of dentition, and premaxillary length. Hatchery-reared juveniles were classified into a normal type similar to wild fish, an ambicolored...
Liquid‐phase deposition (LPD) treatment and anodizing were used to form oxide layer for a high‐capacitance aluminum electrolytic capacitor. Formation of protective oxide layers and modification of LPD conditions make it possible to prolong the LPD duration and lead to the formation of TiO2 and NaF deposits on aluminum. A titanium oxide/aluminum oxide mixed layer was formed by a combination process...
