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

A Potts Neuron Approach to Communication Routing

A feedback neural network approach to communication routing problems is developed, with emphasis on Multiple Shortest Path problems, with several requests for transmissions between distinct start- and endnodes. The basic ingredients are a set of Potts neurons for each request,with interactions designed to minimize path lengths and to prevent overloading of network arcs. The topological nature of

Development of a scoring rubric for A to F grading and assessment of Master’s Theses that are using quantitative methodology

Malmö University uses ECTS grades (A to Fail) in parallel with Swedish grades for some courses. During 2008 and 2009 I was course director for the course Masters Thesis at the International Masters Programme for Public Health at Malmö University, Sweden. After our first examination it was evident that lecturers from different backgrounds had widely disparate grading criteria and the same quantitat

Evaluation of Deferent Daily Cover Using Hydrus 2d/3d Simulation

The most important trends in landfill management policy over the last decade have been the universal adoption of the containment approach to emission control and the increasing legal requirement to install artificial membranes as bottom liners and caps to landfills which is now mandatory in many countries. The landfill cover is one of the most important aspects when designing and constructing land

Kampf um Raum

Recently there has been an upsurge of writings within geography on life itself and the various configurations and procedures that produce and sustain life. There is, of course, an older literature within geography that has emphasized the relation between life and space. I am thinking primarily of the anthropogeography/biogeography of Friedrich Ratzel and his concept Lebensraum and its corollary no
