New substance is additional by supplemental impacts.[128] In an analogous way, the moons Thebe and Amalthea are thought to provide the two distinct elements of the dusty gossamer ring.[128] There may be proof of a fourth ring that will consist of collisional particles from Amalthea that's strung together the identical moon's orbit.[129]
キンギョの養殖場で原因不明の大量死が発生した。大量死を防ぐためには原因究明が必要不可欠と考え、大量死の発生した養殖場での聞き取り調査やサンプリングを行った。ニシキゴイ養殖場においては、業界内で潜水病と呼ばれる、沈んだまま動かなくなる病気が以前から問題視されていた。この病気の原因を解明するため、病魚のサンプリングを行った。これら病魚は外見所見や解剖所見を観察したのち、病理組織学的手法を用いてさらに詳しく調べた。

thirty° when compared with Earth. As the eccentricity of its orbit is 0.049, Jupiter is a little about 75 million km nearer the Sunshine at perihelion than aphelion,[three] which suggests that its orbit is nearly circular. This small eccentricity is at odds with exoplanet discoveries, that have exposed Jupiter-sized planets with incredibly significant eccentricities. Styles suggest this may be as a consequence of there staying two giant planets while in the Photo voltaic Method, as the presence of a 3rd or more large planets has a tendency to induce greater eccentricities.[133]
しかし、体内に溶け込んだ窒素の量が多いと浮上して水面に出た時に、窒素が細胞から溶け出す速度のほうが身体から排出される速度より速くなってしまいます。その結果、血液や細胞の中に窒素の気泡が形成されます。

The atmospheric proportions of hydrogen and helium are near to the theoretical composition in the primordial photo voltaic nebula.[54] Neon in the upper ambiance is made up of twenty elements for every million by mass, which is a few tenth as considerable as in the Sunshine.
What he discovered was a 17-minute hold off inside a normally clockwork eclipse of Io that happened when Earth and Jupiter were farther faraway from each other. Rømer understood that Io’s more info orbital period couldn’t be altering just as a result of distance between Earth and Jupiter, so he created a idea: if only the space concerning the planets was altering, the impression of Io’s eclipse must be using All those 17 added minutes to achieve our eyes on Earth. This principle of Rømer’s was rooted in One more: that mild moved at a fixed velocity. Rømer was capable of use tough calculations of Earth’s diameter and enough time delay from Jupiter to think of a pace of light that was reasonably near the particular adopted value.
観賞魚の疾病には未報告の疾病が多く存在する。本研究ではキンギョとニシキゴイにおける未報告疾病の原因を明らかにするとともに、その治療法や対策法について検討した。治療法や対策法については、観賞魚用薬品メーカーの主催する魚病講習会などで生産者やユーザーに教授した。
人間は地表（１気圧）で快適に暮らせるようにできています。それが海に潜ったり、高山に登ったりすると環境の変化に体がついてこられなくなって、いろいろな障害を起こします。海に潜った時に起こるのを潜水病といい。高い山に登ったときに起こるのを高山病といいます。これらの病気は簡単ではなく、重症の時は死亡することもあるので注意を要します。
