  1. 1. Regulated Proteolysis: The Secrets of Lon : Cellular Roles and Stress-dependent Regulation of the Lon Protease

    Författare :Matthias J. Fink; Kristina Jonas; Axel Mogk; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lon protease; regulated proteolysis; allosteric regulation; Caulobacter crescentus; stress responses; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Proteolysis is crucial in cells to maintain a functional proteome. It is required for removal of damaged and unfolded proteins during protein quality control, and serves as a mechanism to regulate protein levels through regulated proteolysis. LÄS MER

  4. 3. Fractured Rock Masses as Equivalent Continua - A Numerical Study

    Författare :Ki-Bok Min; KTH; []
    Nyckelord :fractured rock masses; equivalent continuum; discrete fracture Network DFN ; Distinct Element Method DEM ; Finite Element Method FEM ; Nuclear Waste Disposal; Coupled Thermo-Hydro-Mechanical Processes;

    Sammanfattning : In this thesis, fractured rock masses are treated asequivalent continua for large-scale analyses of rockengineering projects. Systematic developments are made for thedetermination of equivalent mechanical and hydraulic propertiesof fractured rock masses using a hybrid discrete fracturenetwork - distinct element method (DFN-DEM) approach.

  5. 4. Design and fabrication of hidden hinge monocrystalline silicon micromirrors for maskless lithography

    Författare :Martin Bring; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; isotropic etching; LOCOS; micromirror; maskless lithography; chevron notch; low temperature transfer bonding; fracture toughness;

    Sammanfattning : Micromirror-based maskless lithography has recently received attention as an attractive candidate to tackle challenges associated with the continued de-vice scaling in the semiconductor industry. The micromirrors work by diffrac-tion and the requirements on planarity are very tough, e.g. peak-to-valley dif-ferences of a few nanometers. LÄS MER

  7. 5. Evaluation of rock mass strength criteria

    Författare :Catrin Edelbro; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Sammanfattning : Knowledge of the rock mass behaviour in general, the failure process and the strength in particular, is important for the design of all kinds of underground excavations. One of the most common ways of estimating the rock mass strength is by using a failure criterion. LÄS MER
