  1. 1. Improved Neuropeptide Identification : Bioinformatics and Mass Spectrometry

    Författare :Maria Fälth Savitski; Per Andrén; David Fenyö; Per Svenningsson; Ronald Beavis; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bioinformatics; neuropepides; database; peptide identification; peptide fragmentation; mass spectrometry; tandem mass spectromerty; Bioinformatics; Bioinformatik;

    Sammanfattning : Bioinformatic methods were developed for improved identification of endogenous peptides using mass spectrometry. As a framework for these methods, a database for endogenous peptides, SwePep, was created. It was designed for storing information about endogenous peptides including tandem mass spectra. LÄS MER

  3. 2. A sensitivity analysis of the Winter-Kennedy method

    Författare :Binaya Baidar; Michel J. Cervantes; Mikael Sendelius; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydropower; discharge; Winter-Kennedy; CFD; Sensitivity; Strömningslära; Fluid Mechanics;

    Sammanfattning : Hydropower is among the lowest-cost electrical energy sources due to its long lifespan and lower operation and maintenance cost. The hydro-mechanical components of hydropower plants generally last about four to five decades, then they are either overhauled or replaced. LÄS MER

  4. 3. Improved mass accuracy in MALDI-TOF-MS analysis

    Författare :Martin Kempka; Johan Roeraade; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; MALDI; mass spectrometry; mass accuracy; peak picking; ion formation; proteins; peptides; chip; sample handling; sensitivity.; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Mass spectrometry (MS) is an important tool in analytical chemistry today, particularly in the field of proteomics where identification of proteins is the central activity. The focus in this thesis has been to improve the mass accuracy of MS-analyses in order to improve the possibility for unambiguous identification of proteins. LÄS MER

  5. 4. Body Composition in Adolescents with Type 1 Diabetes : Aspects of Glycaemic Control and Insulin Sensitivity

    Författare :Stefan Särnblad; Jan Åman; Torsten Tuvemo; Jan Bolinder; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Type 1 diabetes mellitus; Adolescent; Body composition; Physical activity; Energy intake; Metformin; Insulin sensitivity; Pediatrik; Paediatric medicine; Pediatrisk medicin;

    Sammanfattning : Excessive weight gain has frequently been reported in adolescents with type 1 diabetes, especially in girls. In general, puberty is associated with reduced insulin sensitivity that is further diminished by overweight. The causes and consequences of excessive weight gain in adolescents with type 1 diabetes are not fully understood. LÄS MER

  7. 5. Phase Sensitive Amplifiers for Free-Space Optical Communications

    Författare :Ravikiran Kakarla; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase sensitive amplifier; sensitivity; optical injection locking; noisefigure;

    Sammanfattning : The demand for high data rate free-space communications is increasing due to the planned future space exploration missions. In the next few years there is a need to increase the speed by 100 times according to NASA, and this necessitates that transmission systems operate at higher carrier frequencies. LÄS MER
