  1. 1. Awareness and Dreaming during Anaesthesia Incidence and Importance

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Peter Samuelsson; Rolf Sandin; Claes Lennmarken; Johan Raeder; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE Surgery Anaesthetics and intensive care Anaesthetics; MEDICIN Kirurgi Anestesiologi och intensivvård Anestesiologi;

    Abstract : The definition of awareness used consistently in this thesis is: Explicit recall of intraoperative events during general anaesthesia. Since there is no objective method to detect awareness, the patients must be interviewed after anaesthesia. The form and timing of the interview is crucial. READ MORE

  2. 2. Interactions between metals and bacteria : Importance for metal speciation

    University dissertation from Linköping : Linköpings universitet

    Author : Lena Brynhildsen; [1991]

    Abstract : The objective of this thesis is to contribute to the understanding of the interactions between metals and microorganisms with respect to* Toxicity of metals (Cd, Cu, Hg, Zn)* Mineralization of metal-organic complexes (citric acid, histidine)* Metal adsorption (Cs, Sr, Eu, Hg, Zn, As)Most of the studies were made on the gram-negative bacterium Klebsiella oxytoca, but the work also involved a Serratia as as well as mixed cultures of microorganisms from soil systems.Most previous studies, reported in the literature, on the toxic effects of metals on microorganisms have been performed at high nutrient levels, despite the fact that microorganisms in nature normally live under energy-limited conditions.

  3. 3. Pancreatic Endocrine Tumourigenesis Genes of potential importance

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Térèse A. Johansson; Barbro Eriksson; Britt Skogseid; Gunnar Westin; Martin Bäckdahl; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pancreatic endocrine tumour; Multiple endocrine neoplasia type 1; Tumourigenesis; Notch signalling; Notch1; Hes1; Neurog3; Neurod1; Men1; Ascl1; Pou3f4; Pdx1; Rpl10; Dlk1; Dkk1; Tph1; menin; MEDICINE Morphology; cell biology; pathology Morphology Tumour biology; MEDICIN Morfologi; cellbiologi; patologi Morfologi Tumörbiologi;

    Abstract : Understanding signalling pathways that control pancreatic endocrine tumour (PET) development and proliferation may reveal novel targets for therapeutic intervention. The pathogenesis for sporadic and hereditary PETs, apart from mutations of the MEN1 and VHL tumour suppressor genes, is still elusive. READ MORE

  4. 4. Seaweed in the tropical seascape Importance, problems and potential

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Stina Tano; Christina Halling; Sofia Wikström; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Seaweed; Macroalgae; Eucheumoids; Non-indigenous; Haplotype; Fish; Nursery; Epifauna; Diversity; Seaweed farming; Zanzibar; East Africa; Tropical; Marine Ecotoxicology; marin ekotoxikologi;

    Abstract : The increasing demand for seaweed extracts has led to the introduction of non-native seaweeds for farming purposes in many tropical regions. Such intentional introductions can lead to spread of non-native seaweeds from farming areas, which can become established in and alter the dynamics of the recipient ecosystems. READ MORE

  5. 5. On large deviations and design of efficient importance sampling algorithms

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Pierre Nyquist; Henrik Hult; Sandeep Juneja; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Large deviations; Monte Carlo methods; importance sampling;

    Abstract : This thesis consists of four papers, presented in Chapters 2-5, on the topics large deviations and stochastic simulation, particularly importance sampling. The four papers make theoretical contributions to the development of a new approach for analyzing efficiency of importance sampling algorithms by means of large deviation theory, and to the design of efficient algorithms using the subsolution approach developed by Dupuis and Wang (2007).
