2020 Week 49
||Noisy oxygen signal? Check the OroboPOS and OroboPOS-Connector for dirty electrical connections.|
Contaminating grease, salt crystals and moisture can be removed with a dry paper cloth or a paper cloth moistened with absolute ethanol.

Oroboros of the month
- Full Circle
- This image was created for the cover of an issue of "Angewandte Chemie" that featured an article on geometric and electronic connections between different types of pericyclic reactions. The background is a page from Woodward and Hoffmann's classic Conservation of Orbital Symmetry.
- The circle is an orobouros - a mythical serpent eating its own tail - that was created by Prof. Tantillo in response to a suggestion by Roald Hoffmann; and emphasizes both the cyclic nature of pericyclic transition structures as well as the fact that the article accompanying this illustration marked Roald's return to the topic of simple pericyclic reactions of hydrocarbons, nearly three decades after he first described many of their key electronic features.

|Some terms in “Mitochondrial physiology” Bioenergetics Communications 2020.1 (States and rates) did not look familiar ― what is the elementary unit [x]?
Fundamental answers, a critical discussion on the SI unit for count, and the meaning of Euclid’s unit and Euclid’s number are presented in an unusual ‘canonical review’:
