We recently disclosed that the biosynthesis of antiviral γ-poly-D-2,4-diaminobutyric acid (poly-D-Dab) in Streptoalloteichus hindustanus involves an unprecedented cofactor independent stereoinversion of Dab catalyzed by PddB, which shows weak homology to

Kinetic approach to evaluate the effects of 3,3'-diaminobenzidine on N mineralization in soils
It has been demonstrated that azo dyes, the xenobiotics widely use in industries, can pose threats to public health. 3,3'-diaminobenzidine (DAB), as a benzidine analogue, is generated from reduction of azo dyes by intestinal or environmental ...

Diskreta ljud: om DAB som radio
Er DAB (Digital Audio Broadcast) den revolution af radiomediet som det ofte er blevet påstået? I sin analyse af DAB forholder Carin Åberg sig kritisk til den måde DAB og det europæiske forskningsprojekt i di- gital distributionsteknik EUREKA-147 har

Dual active bridge (DAB) converter is well suited for deriving a high-power density plug-in hybrid electric vehicle charger. In this case, various DAB operation modes have to be considered, but few papers have established a unified DAB model.

Frequency-domain-based complete loss model for 10 kV/1 MW solid-state transformer
This study proposes a frequency-domain-based loss model for dual active bridge (DAB) inside modular multi-level cascaded solid-state transformer (SST). Previously, the loss model is mainly derived in the time domain and requires enormous modelling effort.
