  1. 1. A study of the molecular pathways of wood formation using peptide mass spectrometry

    University dissertation from Umeå : Sveriges Lantbruksuniversitet

    Author : Robert Nilsson; [2010]
    Keywords : ;

    Abstract : Wood consists essentially of secondary plant cell walls, composed of a cellulose and hemicellulose network impregnated with lignin. It is formed via the development of derivatives of a thin layer of cells (the vascular cambium) into xylem cells through cell division, expansion, secondary wall formation, lignification and, finally, programmed cell death.

  2. 2. Human-Human and Human-Animal Interaction : Some Common Physiological and Psychological Effects

    University dissertation from Swedish University of Agricultural Sciences

    Author : Linda Handlin; Högskolan i Skövde.; Högskolan i Skövde.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; oxytocin; cortisol; prolactin; ACTH; blood pressure; medical interventions; sensory stimulation; interaction; Naturvetenskap; Natural sciences;

    Abstract : The aim of the present thesis was to investigate hormonal and physiological effects in mothers during a breastfeeding session and in dogs and their owners in response to short-term interaction.In study one, sixty-six mothers receiving either exogenous oxytocin infusion and/or epidural analgesia (EDA) during labor or intramuscular oxytocin injection post partum were studied.

  3. 3. Performance Studies and Star Tracking for PoGOLite

    University dissertation from Stockholm : KTH

    Author : Cecilia Marini Bettolo; KTH.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polarization; pulsars; x-ray; PoGOLite; NATURAL SCIENCES Physics Elementary particle physics Astroparticle physics; NATURVETENSKAP Fysik Elementarpartikelfysik Astropartikelfysik;

    Abstract : PoGOLite is a balloon-borne experiment, which will study polarized soft γ-ray emissionfrom astrophysical targets in the 25-80 keV energy range by applying well-typephoswich detector technology. Polarized γ-rays are expected from a wide variety of sources including rotation-powered pulsars, accreting black holes and neutron stars,and jet-dominated active galaxies. READ MORE

  4. 4. CFD of Duct Acoustics for Turbocharger Applications

    University dissertation from Stockholm : KTH

    Author : Emma Alenius; KTH.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aero acoustics; Large Eddy Simulation; IC-engines; 1D models; turbocharger; orifice plate; TECHNOLOGY Engineering physics Acoustics; TEKNIKVETENSKAP Teknisk fysik Akustik; TECHNOLOGY Engineering mechanics Fluid mechanics; TEKNIKVETENSKAP Teknisk mekanik Strömningsmekanik;

    Abstract : The search for quieter internal combustion engines drives the quest for a better understanding of the acoustic properties of engine duct components. In this work the main focus is the turbocharger compressor and a discussion of turbocharger acoustics and earlier work within the area is presented, giving an insight into its sound generating mechanisms and the damping effect it has on pressure pulses, i.

  5. 5. Embedding Theorems for Mixed Norm Spaces and Applications

    University dissertation from Karlstad : Karlstad University

    Author : Robert Algervik; Karlstads universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mixed norms; rearrangements; modulus of continuity; embeddings; Sobolev spaces; Besov spaces; Lorentz spaces; MATHEMATICS Algebra; geometry and mathematical analysis Mathematical analysis; MATEMATIK Algebra; geometri och analys Analys; Matematik; Mathematics;

    Abstract : This thesis is devoted to the study of mixed norm spaces that arise in connection with embeddings of Sobolev and Besov type spaces. We study different structural, integrability, and smoothness properties of functions satisfying certain mixed norm conditions. Conditions of this type are determined by the behaviour of linear sections of functions. READ MORE
