Genetic Traits Beneficial for Xylose Utilization by Recombinant Saccharomyces cerevisiae

Saccharomyces cerevisiae ferments hexoses in lignocellulosic hydrolysates under anaerobic conditions with high rates and ethanol yields. However, S. cerevisiae is naturally unable to utilize the pentose fraction of the hydrolysates. Xylose is the most abundant pentose sugar, and although recombinant S. cerevisiae strains capable of ethanolic xylose fermentation have been obtained through metabolic

Ten Years Of Sustainable Construction Aspects From A North And A South Perspective – A Review From Sustainable Building Conferences 1998-2007.

This paper is about, from a North and South different perspective, how the international focus of sustainable construction issues has changed over the past ten years. It is a review from four different international and regional sustainable building conferences between 1998 and 2007. The paper is mostly based of the first author's notes from the conferences, especially from the plenary sessions an

Statistical MIMO Propagation Channel Models - An overview

Statistical propagation channel models for MIMO systems can be grouped into two classes: physical and analytical. Physical models describe the statistics of the multipath components and are in widespread use for implementation and testing of systems (e.g. 3GPP, IEEE 802.11n). Analytical (or nonphysical) models describe the statistics of the transfer functions between the antenna elements at the tr
