1. 1. Accumulation of 63Ni, 106Ru and 125Sb in phytoplankton

   Master-uppsats,

   Författare :Yusuf Ali; [2022-08-22]
   Nyckelord :Medical physics; Environmental radiology; Nuclear Power Plants; concentration factor CF ; phytoplankton; phaeodactylum tricornutum; radioactive releases; nickel; ruthenium; antimony; gamma spectroscopy; liquid scintillation counting;

   Sammanfattning : Background: Nuclear Power Plants (NPPs) release small amounts of radionuclides which contribute with a low radiation dose to the environment as well as humans and animals. In this context, marine ecosystems are critical, since most NPPs in Sweden are located by the sea. LÄS MER

3. 2. Identification of Neutrons Using Digitized Waveforms

   Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Rasmus Kjær Høier; [2019]
   Nyckelord :Digitizer; neutron; gamma-ray; pulse-shape discrimination; CNN; convolutional neural network; charge comparison; time of flight; source-testing facility; STF; Physics and Astronomy;

   Sammanfattning : The advantages of performing neutron-tagging measurements using a waveform digitizer are explored. An existing analog setup consisting of modular crate electronics at the Source-Testing Facility at the Division of Nuclear Physics in Lund, Sweden has been digitally replicated. LÄS MER

4. 3. Design, Construction and Characterization of a Portable Fast-Neutron Detector

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

   Författare :Nicholai Mauritzsson; [2017]
   Nyckelord :fast-neutrons; detector; plastic scintillator; NE110; neutron tracking; scintillation; spallation; european spallation source; sonnig; Physics and Astronomy;

   Sammanfattning : At European Spallation Source ERIC, 2 GeV proton bunches will be accelerated towards a tungsten target where spallation will occur, producing a wide neutron energy spectrum. Despite the shielding and moderators in place to stop and/or reduce their energy, a significant portion of the most energetic neutrons, called prompt neutrons, might still reach the sample position of a neutron-scattering instrument.

5. 4. Construction and evaluation of plasma protein multilayers used for local drug delivery

   Master-uppsats, Institutionen för fysik, kemi och biologi

   Författare :Sandberg Olof; [2010]
   Nyckelord :fibrinogen; albumin; IgG; bisphosphonate; antibiotic; local drug delivery;

   Sammanfattning : With the studies performed in this theses the local drug delivery technique FibMat developed by the biotech company AddBIO, was shown to be applicable to other plasma proteins and drugs than the fibrinogen-bisphosphonate combination that is today being commercialized. Hence the potential for a broader field of application was demonstrated. LÄS MER

7. 5. Local Delivery of Bisphosphonates from FibMat Matrix

   Uppsats för yrkesexamina på grundnivå, Institutionen för fysik, kemi och biologi

   Författare :Henrik Aronsson; [2008]
   Nyckelord :FibMat; matrix; bisphosphonate; fibrinogen; thrombin; implant; coagulation assay; gamma irradiation; bone resorption; liquid scintillation; autoradiography; local delivery; drug;

   Sammanfattning : Improving the functionality and reducing revision rates are important driving forces in the development of orthopaedic implants. FibMat is a fibrinogen based matrix developed towards commercialisation by the company Optovent AB. This matrix can be coated on implants and act as a local drug delivery system for bisphosphonates (BPs). LÄS MER
