11. Vad är en icke-användare? : En begreppsanalys av begreppet icke-användare i folkbibliotekskontexter
Master-uppsats, Högskolan i Borås/Akademin för bibliotek, information, pedagogik och ITSammanfattning : There is a discrepancy in research within library and information science in the use of the concept non-user, and no research about librarians’ use of the concept can be found. If librarians define the concept differently it may affect how they share experiences with one another and how they design outreach towards library non-users. LÄS MER
12. Automatic Interpretation of Ion Beam Measurements of Walls in Fusion Machines
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The purpose of this study is to investigate whether it is possible to automatically interpret theresults of Time-of-flight Elastic Recoil Detection Analysis (ToF-ERDA). And if so, find out if the automaticinterpretation is quicker and/or more accurate than the current approach that consists of manualanalysis. LÄS MER
13. Utvärdering av effekter på artidentifiering vid förlängda tidsintervall mellan mikroorganism- och matrixapplicering med MALDI-TOF MS
Kandidat-uppsats, Jönköping University/HHJ, Avdelningen för naturvetenskap och biomedicinSammanfattning : Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) är en viktig metod för artidentifiering av mikroorganismer på kliniska mikrobiologiska laboratorier. Enligt rekommendationer från Bruker Daltonics skall matrixapplicering ske relativt omedelbart efter att mikroorganismer har applicerats. LÄS MER
14. Effects of reconstruction parameters on the image quality and quantification of PET images from PET/MRI and PET/CT systems
Master-uppsats,Sammanfattning : Aim: To study how reconstruction parameters affect the positron emission tomography (PET) image quality and quantitative results for the different lesion to background radioactivity ratios in three different PET systems. Introduction: Multimodality imaging that combines magnetic resonance imaging (MRI) or computed tomography (CT) with a PET system can produce medical images containing both functional and anatomical information.

15. Investigation of the Plasma delay time in PIPS detectors using the LOHENGRIN spectrometer
L3-uppsats, Uppsala universitet/Tillämpad kärnfysikSammanfattning : This project has examined the effects of plasma delay time (PDT) and pulse height defect (PHD) for protons, tritons and alpha particles. The goal was to determine PDT and PHD for alpha particles relative to protons, by using data from a subset of measurements taken with a silicon detector of type PIPS at the LOHENGRIN spectrometer.
