1. 1. Measuring bacterial metabolism and antibioticsusceptibility : using silicon nanowire field-effect transistor.

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : George Alhoush; [2024]
   Keywords : Silicon nanowire field effective transistor; SiNWFET; Ion-selective filed effect transistor; ISFET; Antibiotic susceptibility test; AST; Measuring bacterial metabolism using microchip;

   Abstract : Antimicrobial resistance is considered by many prominent researcher and scientist as a profound global health crisis that us humans must face in the next decade. It is threatening the effectiveness of these once-reliable weapons against bacterial infections and leaving us susceptible to pathogenic agents. READ MORE

3. 2. A Novel Method for Measuring Low Energy Excitations with BLS

   University essay from Uppsala universitet/Materialfysik

   Author : Christopher Borchert; [2024]
   Keywords : ;

   Abstract : This report presents the work done on an optical setup combining Raman and BLS spectroscopy and discusses the achieved improvements of the system. After some general optimization and minor redesigning, a new alternative beam path was implemented. READ MORE

4. 3. Effectiveness of Iterative Algorithms for Recovering Phase in the Presence of Noise for Coherent Diffractive Imaging

   University essay from Göteborgs universitet / Institutionen för fysik

   Author : Henry Wittler; [2023-11-29]
   Keywords : ;

   Abstract : Methods of coherent diffractive imaging (CDI) rely on iterative algorithms to reconstruct the complex exit-surface wave (ESW) of the object being imaged from the measured diffraction intensity only. In this thesis we investigate by simulation the artifacts on reconstruction when noise are present in the measurement. READ MORE

5. 4. If Trees Could Talk - Dendrochemistry, a Promising Method for Understanding Pollution History

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Jonatan Uusitalo; [2023-08-17]
   Keywords : ;

   Abstract : Heavy metal pollution presents a significant environmental challenge in the Anthropocene era, and understanding pollution history is crucial to address historical pollution and implementing effective mitigation measures. This study stands among a few comprehensive dendrochemical investigations that utilized an extensive dataset and energy dispersive X-ray fluorescence (EDXRF) technique to reconstruct the contamination history of As, Cd, Cu, Ni, Pb, and Zn, with a focus on Cu.

6. 5. Preprocessing for intravoxel incoherent motion analysis in the brain - Signal drift correction

   University essay from

   Author : Amina Warsame; [2023-04-17]
   Keywords : Medical physics; Diffusion magnetic resonance imaging; dMRI; Intravoxel incoherent motion; IVIM;

   Abstract : Diffusion magnetic resonance imaging (dMRI) is a diagnostic imaging technique that is sensitized to the movement of water molecules in tissues. Intravoxel incoherent motion (IVIM) analysis can be used to estimate blood flow in capillaries from weakly diffusion-weighted data. READ MORE
