Fermentation of Lignocellulosic Hydrolysates: Inhibition and Detoxification

The ethanol yield and productivity obtained during fermentation of lignocellulosic hydrolysates is decreased due to the presence of inhibiting compounds, such as weak acids, furans and phenolic compounds produced during hydrolysis. Evaluation of the effect of various biological, physical and chemical detoxification treatments by fermentation assays using Saccharomyces cerevisiae was used to charac

Laser-driven particle acceleration - Experimental investigations

This thesis describes experimental studies of laser-driven particle acceleration. With the focused intensity of today’s high-power lasers exceeding 10^18 W/cm2,extremely high-gradient accelerators are possible. A number of experiments have been performed using two different laser systems, the Lund multi-TW laser and the Vulcan laser at CLF/RAL, UK, to study aspects ranging from laser system optimi

MIMO systems with antenna selection - an overview

We consider multiple-input - multiple-output (MIMO) systems with reduced complexity. Either one, or both, link ends chose the "best" L out of N available antennas. This implies that only L instead of N transceiver chains have to be built, and also the signal processing can be simplified. We show that in ideal channels, full diversity can be achieved, and also the number of independent data streams

Flexible Learning in a Digital World

Abstract Concepts as flexible learning, lifelong learning, life wide learning, individualization, globalization are discussed. What does it mean and what are the consequences on HEI perspectives. The critical issue is who are the learners and the learning providers and what are their frames of references.
