1. 1. The experience of being new and desirable support during the first year in the emergency medical services

   Författare :Anna Hörberg; Karolinska Institutet; Karolinska Institutet; Stockholm Karolinska Institutet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : The emergency medical services (EMS) has been described as a challenging professional practice where the persons in need of care vary greatly in terms of age, symptoms and situations. There is limited research regarding the experience of being new to this line of work, and what support new professionals desire during their first year in a professional practice like the EMS.

3. 2. Unravelling Mechanistic Insights of Eukaryotic Transcriptional Control

   Författare :Johanna Hörberg; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transcriptional control; Gene expression regulation; DNA supercoiling; DNA methylation; DNA-protein recognition; Basic-Leucine-Zipper transcription factors; Basic-Helix-Loop-Helix transcription factors; Sequence specific DNA plasticity; Transcription factor cooperativity; Cancer; Molecular modelling; Molecular dynamics;

   Sammanfattning : DNA transcription involves the association of multiple proteins with DNA to convert the genetic information into messenger-RNA transcripts, which later will be translated into proteins. Con-trolled regulation of transcription is imperative for preserving the healthy and homeostatic state of cells. LÄS MER

4. 3. An Experimental Investigation of Shape Distortions in Aerospace Composites

   Författare :Erik Hörberg; Malin Åkermo; Stefan Hallström; Patrik Fernberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flyg- och rymdteknik; Aerospace Engineering;

   Sammanfattning : Composite materials are increasingly used in primary structure of modern commercial aircraft. Its excellent material characteristics enables reduction of structural weight compared to traditional metal solutions and thereby offers reduction of fuel consumption and carbon dioxide (CO2) emissions.

5. 4. Low Phase Noise GaN HEMT Oscillator Design based on High-Q resonators

   Författare :Mikael Hörberg; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resonator coupling; reflection oscillator; MMIC; phase noise; cavity resonator; low-frequency noise; GaN HEMT; MEMS;

   Sammanfattning : The thesis considers the design and optimization of oscillators targeting low phase noise, given boundary conditions from the technology. Crucial technology figures are power capability, RF noise figure, low-frequency noise and the quality factor (Q-factor) of the resonator. LÄS MER

7. 5. Optimum GaN HEMT Oscillator Design Targeting Low Phase Noise

   Författare :Mikael Hörberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low frequency noise; resonator coupling; cavity resonator; GaN HEMT; MMIC; reflection oscillator; phase noise;

   Sammanfattning : The thesis considers design of low phase noise oscillators, given the boundary condition of the used technology. Important conditions are the power handling of the active device, device noise floor, the quality factor of the resonator, bias settings, and low frequency noise. LÄS MER
