Inter- stingly, the bond angles (168.8 and 172.5) of the bridge (Si2-O9-Si6 and Si4-O10-Si8) were considerably expended, and bigger than those in the deck or cubic structure. Yoshida's product was not completely consistent with the proposed double decker structure. It was con- ...
In order to promote convenient strategies for the valorization of Aucoumea klaineana Pierre (Okoume) plywood and sawmill wastes industry in the fields of adhesives and composites, the total phenolic content of Okoume bark, sapwood and heartwood was measured. The molecular structure of tannins extracte...
Owing to their excellent pharmacological activity, the compounds according to the first aspect of the invention, in particular according to the general structure of formulae (I), (I-A), (I-B), (I-B-1) (I-B-2), (I-B-3), (I-C) and (I-D) are suitable for the treatment of ...
The new condensed as-triazine derivatives differ also qualitatively from known compounds of similar structure. The compounds of the general Formula I are practically void of antiarrhythmial, spasmolytic and antitremorine effect, while a part of these new compounds exhibit a significant narcosis potentia...
