  2. 1. Nitric oxide in central nervous structures associated with water balance and micturition

    Author : Anders Nylén; Lunds universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacological sciences; spinal projections; True Blue; cystometry; circumventricular organs; paraventricular nucleus; supraoptic nucleus; NADPH diaphorase; immunohistochemistry; oxytocin; 8-arginine-vasopressin; hypothalamus; rat; micturition; nitric oxide; water balance; neuronal nitric oxide synthase; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Abstract : The role of nitric oxide (NO) in the central control of water balance and micturition has not yet been established. In the present thesis, where female rats were used, neuronal NO synthase (nNOS) distribution was studied in structures of the central nervous system known to be associated with the above mentioned control.

  4. 2. Endoglucanase and Mannanase from Blue Mussel, Mytilus edulis: Purification, Characterization, Gene and Three Dimensional Structure

    Author : Bingze Xu; Folke Tjerneld; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Bioteknik; Bioengineering; Bioteknik; Surface Biotechnology; ytbioteknik;

    Abstract : Two polysaccharide-degrading enzymes (endo-1,4-D-glucanase and β-mannanase) from blue mussel, Mytilus edulis, have been purified to homogeneity using a combination of several chromatographic steps. Each enzyme has been characterized with regard to its molecular weight, isoelectric point, pH and temperature stability, pH and temperature optimum and substrate specificity. READ MORE

  5. 3. Characterization of domain switching and optical damage properties in ferroelectrics

    Author : Junji Hirohashi; Fredrik Laurell; Ady Arie; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quasi-phase matching; ferroelectric domains; stoichiometric LiNbO3; stoichiometric LiTaO3; KTiOPO4; KNbO3; polarization switching; periodic electric field poling; optical damages; Optical physics; Optisk fysik;

    Abstract : Nonlinear optical frequency conversion is one of the most important key techniques in order to obtain lasers with wavelengths targeted for specific applications. In order to realize efficient and tailored lasers, the quasi-phase-matching (QPM) approach using periodically-poled ferroelectric crystals is getting increasingly important. READ MORE

  6. 4. Properties and applications of materials based on graphite oxide

    Author : Andreas Nordenström; Aleksandr V. Talyzin; Thomas Wågberg; Andrey Turchanin; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Graphene; Graphite Oxide; Graphene Oxide; Swelling; Phase Transition; Intercalation; Activated Graphene; Activated Carbon; Supercapacitors; Neutron Reflectometry;

    Abstract : Graphite oxide (GO) is a hydrophilic, layered material prepared by oxidation of graphite. In the first part of this thesis, we studied materials produced from GO by intercalation and functionalization. The second part of the thesis was focused on supercapacitor applications of high surface area carbons prepared from GO using chemical activation. READ MORE

  7. 5. Time-resolved plasmonics in designed nanostructures

    Author : Eleonora Lorek; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasmon; Nanostructure fabrication; High-order harmonic generation; Photoemission electron microscopy; Focused ion beam; Fysicumarkivet A:2016:Lorek;

    Abstract : A metal nanoparticle can be considered as consisting of a base of positive ion cores and a sea of free electrons. When the free electrons are displaced, for example, by an incident electric field, a restoring force acts on the electrons. The electrons may then oscillate back and forth until equilibrium is reached. READ MORE
