  1. 1. Combined structural methods to characterize an oligomeric small heat shock protein Hsp21

    University dissertation from Lund University, Faculty of Science, Department of Chemistry, Division of Biochemistry and Structural Biology

    Author : Gudrun Rutsdottir; Lunds universitet.; Lund University.; [2017-05]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Small heat shock proteins; chaperones; crosslinking mass spectrometry; Stable isotope labeling; quantification; small angle X-ray scattering; cryo-electron microscopy; combined structural methods; plant stress;

    Abstract : Undersökning av Hsp21 med korslänknings-masspektrometriMänniskans kropp består av ungefär 30 trillioner celler och varje cell innehåller omkring 100 000 proteiner. Föreställ dig om kroppen vore jordklotet, varje vävnad ett land och varje cell en stad. Varje stad vore då konstant som Paris i rusningstrafiken. READ MORE

  2. 2. Parenting stress : Conceptual and methodological issues

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Monica Östberg; Uppsala universitet.; [1999]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Parenting stress; dimensionality; validity; structural equation modeling; social support; infant temperament; responsiveness; Psykologi; SOCIAL SCIENCES Social sciences Psychology; SAMHÄLLSVETENSKAP Socialvetenskap Psykologi; Psychology; psykologi;

    Abstract : High parenting stress has been connected with negative consequences for both parent and child. The aim of the present thesis was to examine factors contributing to high stress, and to develop a psychometrically sound, reliable, and valid instrument for measuring parenting stress. READ MORE

  4. 4. The strength of glulam beams with holes - A probabilistic fracture mechanics method and experimental tests

    University dissertation from Department of Construction Sciences, Lund University

    Author : Henrik Danielsson; Lunds universitet.; Lund University.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fracture mechanics; Weibull; design; test; strength; stress; glulam; hole; probabilistic fracture mechanics.;

    Abstract : This thesis deals with experimental tests and methods for strength analysis of glulam beams with holes. Test results and methods for strength analysis available in literature are compiled and discussed. The methods considered comprise both code strength design methods and more general methods for strength analysis. READ MORE

  5. 5. Moisture Induced Stress Perpendicular to Grain in Timber Structures

    University dissertation from Div. of Structural Engineering, Lund University

    Author : Martin Häglund; Lunds universitet.; Lund University.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood.; timber; perpendicular to grain; load combination factor; tensile stress; mechano-sorption; Moisture induced eigen-stress; varying moisture content;

    Abstract : Timber structures and wooden element are in general affected by moisture and moisture variation in different ways. Their hygroscopic properties result in adsorption of water when wetted and in desorption when dried. READ MORE
