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
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 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

This paper summarises the outcome of an experimental study, which is related to a winding arrangement in a stator core that is made of Soft Magnetic Mouldable Composite – SM2C. The comparison is made between a distributed concentrated winding and a modular wave-winding, where the modular wave-coils are distributed either axially or circumferentially. Manufacturability and high winding fill factor
