… Various conditions of the number of blades, incidence angles and cavitation numbers were considered. … When the incidence angle increased or the cavitation number decreased, the steady balanced cavitation transited to unsteady and non-uniform patterns. … In most cases of rotating partial cavitation, except for 4-blades, the cavity develops in the second passage of backward direction after the decay of largest cavity. …

平成16年に検定済の保健学習用教科書について,「むし歯」と「歯周病」とそれらの予防方法をはじめとした記述内容について検討したところ,20世紀の歯科研究の成果を反映している内容とは考えられなかった.そこで,小学校の保健学習用教科書の歯科関連の記述に,以下の3点を盛り込む必要がある.「むし歯」とその効果的な予防方策として,う蝕の成り立ちと修復(再石灰化)の過程を正しく記述する.また,歯磨きでう蝕が防げ …

… A comprehensive spectral analysis of data from the surveillance of infectious diseases in Japan on the weekly incidences of measles, chickenpox, mumps and rubella was carried out using a computing program known as "MemCalc." Each power spectral density (PSD) indicated exponential decay until it leveled off at a limit determined by the accuracy of the present data. …
