1. 1. Visualizing Interacting Biomolecules In Situ

   Författare :Irene Weibrecht; Ola Söderberg; Ulf Landegren; Banafshe Larijani; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proximity ligation; in situ PLA; padlock probe; rolling circle amplification; flow cytometry; in situ; single cell; single molecule; protein interaction; protein-DNA interaction; posttranslational modification; Molecular medicine; Molekylär medicin; Molekylär medicin; Molecular Medicine;

   Sammanfattning : Intra- and intercellular information is communicated by posttranslational modifications (PTMs) and protein-protein interactions, transducing information over cell membranes and to the nucleus. A cells capability to respond to stimuli by several highly complex and dynamic signaling networks provides the basis for rapid responses and is fundamental for the cellular collaborations required in a multicellular organism.

3. 2. Analysis of Arctic ice cloud properties using in-situ and remote sensing measurements

   Författare :Veronika Wolf; Thomas Kuhn; Peter Völger; Martin Gallagher; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic cirrus clouds; ice particle properties; in-situ measurements; in-situ and lidar comparison; Atmospheric science; Atmosfärsvetenskap;

   Sammanfattning : Cirrus clouds play an important role in the radiation balance of the atmosphere as theycan have a warming and cooling effect. The resulting net radiation effect depends ontheir micro- and macrophysical properties such as particle size, shape, and numberconcentration. LÄS MER

4. 3. Improving accuracy of in situ gamma-ray spectrometry

   Författare :Jonas Boson; Christer Samuelsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gamma-ray spectrometry; in situ measurement; HPGe detector; 137Cs; Monte Carlo; efficiency calibration; measurement uncertainty; Radiological physics; Radiofysik;

   Sammanfattning : Gamma-ray spectrometry measurements performed on site, or “in situ”, is a widely used and powerful method that can be employed both to identify and quantify ground deposited radionuclides. The purpose of this thesis is to improve the calibration of high purity germanium (HPGe) detectors for in situ measurements, and calculate the combined uncertainty and potential systematic effects.

7. 5. Ionic transport of α-alumina below 1000°C : an in-situ impedance spectrosocpy study

   Författare :Johan Öijerholm; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; α-alumina; in-situ impedance spectroscopy; molecular dynamics; spark plasma sintering; conductivity; microstructure; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Sammanfattning : Ionic conductivity of metal oxides is critical for the function of a broad range of different components, such as electrolytes in solid oxide fuel cells and alloys designed for high temperature applications. In both cases the ionic conductivity can be studied by in situ impedance spectroscopy, which is also able to reveal information on the dielectric properties of the metal oxides, and in some cases the influence of their microstructure.
