Physiologische Untersuchungen über die Eireifung bei Pomatoceros triqueter L.

Ohne ZusammenfassungDie Untersuchungen wurden an der Zoologischen Station Kristineberg, Schweden, ausgeführt. Es ist mir eine angenehme Pflicht, dem Direktor, Herrn ProfessorHjalmar Théel, und dem Vorstand, Herrn Dr.Hjalmar Östergren, meinen besten Dank auszusprechen. Schließlich richte ich den herzlichsten Dank an Herrn Dr.John Runnström, Stockholm, der mir die Idee der Untersuchung gegeben und mit größtem Interesse und größter Freundlichkeit meine Arbeit geleitet hat.

Four-site four-electron model for Bi(III)-Bi(V) mixed valence complex

In most quantum models for the four-site four-electron problem the lowest singlet state has two short and two long bonds in the absence of lattice polarization and is called the resonating valence bond (VB) state. It is shown here that if the lattice polarization is large, the ground state is a ‘negative U’ state with valence disproportionation (for example BaBiO₃ with Bi(V) and Bi(III) sites). Furthermore the model shows that the coupling between the pairs on different sites is provided via the VB state.     

What Are the Health Risks of Eating Red Meat,and How Should We Assess Them?

This paper discusses possible mechanisms that might lead to misinterpretations of collected data and makes new evidence-based medicine (EBM) recommendations to oppose the previously accepted preventive measures, or treatment options. It is focused on the danger of the “red meat” consumption, and the question whether eating pungent food is good or bad for our health and finally whether the “bad luck” concept of getting several cancer types is valid or not. These three topics got and still have significant media attention. Several mechanisms are proposed as possible causes of these apparent conflicts. Some of them have already been recognized but sadly remained less known to medical readers and also to the general population. Also see the video abstract here https://youtu.be/owjoRXrNShA .
