  2. 1. Exploring and exploiting plant biomass degradation by Bacteroidetes

    Author : Cathleen Kmezik; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; polysaccharide utilization locus; plant biomass degradation; carbohydrate esterases; multidomain enzymes; Bacteroidetes; PUL transfer; carbohydrate-active enzymes; xylan;

    Abstract : Bacteroidetes bacteria have evolved to become excellent biomass degraders. They achieved this by applying carbohydrate-active enzymes (CAZymes) and organizing genes connected to the degradation of specific polysaccharides into discrete gene cassettes, so-called polysaccharide utilization loci (PULs).

  4. 2. Histamine receptors and neuropeptides in the cranial circulation

    Author : Anders Ottosson; Rättsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurophysiology; neuropsychology; Neurology; Human - arteries - CGRP - SP - mast cells; Neurologi; neuropsykologi; neurofysiologi;

    Abstract : The sensory neuropeptides substance P (SP) and calcitonin gene-related peptide (CGRP) are present in human cerebral, meningeal and temporal arteries, as are peptides associated with the sympathetic (neuropeptide Y, NPY) and parasympathetic (vasoactive intestinal peptide, VIP) nervous system. NPY is a vasoconstrictor in cerebral and meningeal arteries and potentiates noradrenaline (NA) as a vasoconstrictor in temporal arteries. READ MORE

  5. 3. NMR Studies of Gel-Emulsions; Diffusometry and Applications of Novel Field Gradient Techniques

    Author : Carin Malmborg; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; modulated gradients; imaging; Physical chemistry; Fysikalisk kemi; NMR; emulsion; diffusion;

    Abstract : The aim of these studies has been to investigate what information that can be obtained on gel-emulsions with nuclear magnetic resonance, NMR, as the investigating tool. The gel-emulsions are important in many technical applications such as in food products, in cosmetic and pharmaceutical formulations, and in emulsion explosives, just to name a few applications.

  6. 4. Flight Simulator Training : Assessing the Potential

    Author : Staffan Magnusson Nählinder; Kjell Ohlsson; Nils Dahlbäck; Erland Svensson; Ken R. Boff; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Work sciences and ergonomics; Arbetsvetenskap och ergonomi;

    Abstract : Mental workload is an important concept and has been proven to be a precursor to situation awareness and operative performance. This thesis describes methods to measure mental workload through self-ratings and psychophysiological measurements. READ MORE

  7. 5. Nonlinear optics in KTiOPO4 for spectral management of ultra-short pulses in the near- and mid-IR

    Author : Anne-Lise Viotti; Valdas Pasiskevicius; Fredrik Laurell; Paulina Kuo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nonlinear optics; Ferroelectrics; Fysik; Physics;

    Abstract : This thesis explores the possibilities of controlling nonlinear optical interactions in ferroelectric materials for bandwidth tailoring of ultrashort pulses in the pico- and femto-second range. The control is achieved through quasi-phase matching, which is based on alternating the material’s spontaneous polarization into different domains. READ MORE
