  1. 1. In situ X-Ray Spectroscopy of Ethylene Epoxidation over Ag and studies of Li-ion batteries and Cu sulfidation

    Author : Paw Kristiansen; Laurent Duda; Thorsten Schmitt; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; In situ; XAS; RIXS; heterogeneous catalysis; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : This thesis is based on experiments applying synchrotron based X-ray Absorption Spectroscopy(XAS) and Resonant Inelastic X-ray Scattering (RIXS) in the soft X-ray region to energy related systems. The main work of this thesis has been to develop a reaction cell that allowed for in situ XAS and RIXS investigations of the partial epoxidation of ethylene over a Ag catalyst at 1 atm and up to 250C.

  2. 2. Contributions of calcitonin gene-related peptide in ischemia, inflammation and nociception

    Author : Gunilla Brodda Jansen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : 5-hydroxytryptamine; acupuncture; blood flow; calcitonin gene-related pep- tide; edema formation; histamine; inflammation; ischemia; mast cells; neuropeptides; neutrophils; nociception; sensory stimulation; substance P; surgical flaps; withdrawal res;

    Abstract : The sensory neuropeptide Calcitonin gene-related peptide (CGRP) is a very potent vasodilator with a wide distribution in peripheral sensory nerves, often co-stored with substance P. In the present study, the effects of CGRP in different models of ischemia, inflammation and nociception were examined. READ MORE

  3. 3. Artificial Neural Networks (ANN) in the Assessment of Respiratory Mechanics

    Author : Gaetano Perchiazzi; Göran Hedenstierna; Björn Jonson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; artificial neural networks; respiratory system compliance; respiratory system resistance; respiratory system time constant; intrinsic positive end expiratory pressure; PEEPi; animal model; acute lung injury; oleic acid; Otis model; Fysiologi; Physiology; Fysiologi;

    Abstract : The aim of this thesis was to test the capability of Artificial Neural Networks (ANN) to estimate respiratory mechanics during mechanical ventilation (MV). ANNs are universal function approximators and can extract information from complex signals. READ MORE

  4. 4. Sleep Apnoea in Patients with Stable Congestive Heart Failure - An Intervention Study with a Mandibular Advancement Device

    Author : Mahmoud Eskafi; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sömnapné; Bettfysiologi; Hjärtsvikt;

    Abstract : In patients with congestive heart failure (CHF), sleep disordered breathing (SDB)--including obstructive and central sleep apnoea as well as periodic breathing--is a common condition and is believed to increase the risk of mortality. Treatment of SDB is considered important in the management of CHF. READ MORE

  5. 5. Biologically active terpenoids from Bolivian medicinal plants

    Author : Maribel Lozano Palacios; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bolivian plants; cytotoxicity; triterpenes; damsin; breast cancer;

    Abstract : Pseudo-guaianolides represent a large group of sesquiterpene lactones exhibiting significant cytotoxic and anti-inflammatory activities. Their biological activities are due to a 훼-methylene-훾-lactone unit in their chemical structure, which reacts with free sulfhydryl groups of free cysteine via a Michael-addition. READ MORE
