  1. 1. Characterizing the pancreatic "isletome" : 3D optical imaging to study diabetes

    Författare :Max Hahn; Ulf Ahlgren; András Gorzsás; Leif Carlsson; Alvin C. Powers; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D imaging; fluorescence microscopy; 3D image analysis; technique development; diabetes; Islet of Langerhans; Insulin; β-cell mass; pancreas; anatomy; molecular medicine medical sciences ; molekylär medicin medicinska vetenskaper ; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : The pancreas is a specialised multipurpose organ, that can be separated into two major compartments: endocrine and exocrine. The exocrine part makes up the majority of the organ volume and functions to secrete digestive enzymes into the small intestine. LÄS MER

  3. 2. On Multidimensional Dynamic Fluorescence Imaging and Quantitative Image Analysis in Wide-Field Microscopy Applications to Studies of Astroglial Cells

    Författare :Siamak Khatibi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; volume estimation; astrocyte; calcium wave; intercellular signaling; volumetric image analysis; fluorescence imaging; three-dimensional 3D reconstruction; segmentation;

    Sammanfattning : Modern biological research has benefited from a renaissance in light microscopy, brought about by the convergence of developments in fields as diverse as electronics, optics, molecular biology, computer science, and reagent chemistry. Integration of these has transformed microscopy into a highly useful, dynamic research tool for biology and medicine. LÄS MER

  4. 3. 3D nano-tomography using coherent X-rays

    Författare :Maik Kahnt; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ptychography; Tomography; Phase reconstruction; X-ray microscopy;

    Sammanfattning : X-rays allow to non-destructively investigate biological, chemical or physical processes at the nano-scale. Their high penetration depth in matter allows to investigate samples even inside sample environments, which would be difficult with complementary methods such as transmission electron microscopy (TEM).

  5. 4. Direct Fourier methods in 3D-reconstruction from cone-beam data

    Författare :Caroline Axelsson; Michel Defrise; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The problem of 3D-reconstruction is encountered in both medical and industrial applications of X-ray tomography. It would seem natural to recover volume data by just repeating 2D-reconstructions slice-by-slice. LÄS MER

  7. 5. Advanced Optical Diagnostics in Particle Combustion for Biomass and Metal as Alternative Fuels

    Författare :Shen Li; Förbränningsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical diagnostics; Quantitative measurement; Iron powder; Biomass; High-speed imaging; Digital holography; 3D reconstruction; SEM; Fysicumarkivet A:2022:Li;

    Sammanfattning : The energy sector is in urgent need for carbon-free strategies considering environmental pollutions and climate change impact. Two kinds of solid fuels, biomass and metal particles have been studied in this thesis aiming at CO2 emission reduction or zero carbon emission. LÄS MER
