Physiological and behavioral responses in human fear of bears and wolves.

Research on human emotions towards large carnivores is often based on self-reported emotions. This study aimed to investigate physiological and behavioral responses to feared animals among people who say that they are fearful or not fearful of brown bear and wolf. Participants were recruited to be bear fearful only (n=8), fearful of both bear and wolves (n=15), or fearful of neither carnivore (n=1

Enzymatic Reduction of Ketones

Methods have been studied for the production of chiral alcohols, which are of importance in organic synthesis of pharmaceuticals, agro-chemicals and fragrances, etc., through the enzymatic or microbial reduction of ketones. Classical reaction engineering was combined with genetic engineering to improve the production of chiral alcohols and kinetic resolution of racemic ketones with high enantiomer

On the time-domain version of the optical theorem

The time-domain version of the optical theorem is discussed. From the theorem and causality fundamental results concerning the scattered and absorbed energies from an incident plane pulse are obtained. Some results are verified by numerical calculations.
