Peter Ascanius (24 May 1723 – 4 June 1803) was a Norwegian biologist. He was born at Aure in Møre og Romsdal, Norway. He was a student of Linnaeus. He taught zoology and mineralogy in Copenhagen from 1759 to 1771, and later worked as a supervisor at the mines in Kongsberg and elsewhere in Norway. Among his published wo... | https://en.wikipedia.org/wiki?curid=3534272 |

Sphaerobacter is a genus of bacteria. When originally described it was placed in its own subclass (Spahaerobacteridae) within the class Actinobacteria. Subsequently, phylogenetic studies have now placed it in its own order Sphaerobacterales within the phylum Chloroflexi. Up to now there is only one species of this genu... | https://en.wikipedia.org/wiki?curid=3538896 |
Infradian rhythm In chronobiology, an infradian rhythm is a rhythm with a period longer than the period of a circadian rhythm, i.e., with a frequency less than one cycle in 24 hours, such as menstruation, breeding, tidal or seasonal rhythms. In contrast, ultradian rhythms have periods shorter than the period of a circa... | https://en.wikipedia.org/wiki?curid=3541535 |
Surface freezing is the appearance of long-range crystalline order in a near-surface layer of a liquid. The surface freezing effect is opposite to a far more common surface melting, or premelting. Surface Freezing was experimentally discovered in melts of alkanes and related chain molecules in the early 1990s independe... | https://en.wikipedia.org/wiki?curid=3552981 |
Isoscalar In particle physics, isoscalar refers to the scalar transformation of a particle or field under the SU(2) group of isospin. It is a singlet state, with total Isospin 0 and the third component of Isospin 0, much like a singlet state in a 2-particle addition of Spin. See also isovector. | https://en.wikipedia.org/wiki?curid=3559700 |
Isovector In particle physics, isovector refers to the vector transformation of a particle under the SU(2) group of isospin. An isovector state is a triplet state with total isospin 1, with the third component of isospin either 1, 0, or -1, much like a triplet state in the two-particle addition of Spin. See also Isosca... | https://en.wikipedia.org/wiki?curid=3559710 |
