  1. 26. Distributed gateways for terabit/s satellite : Study of smart gateway diversity

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Florian Romain Gain; [2011]
    Keywords : ;

    Abstract : Future Satcom systems will be required to provide Internet at high capacity to an increasing number of users. Because of demanding applications the throughput should approach the Tb/s. To achieve such a data rate, large bandwidths are required. So considering spectrum congestion below 15 GHz, communications should use Ka and Q/V bands. READ MORE

  3. 27. Collimation technique for HPGe-detector gamma spectrometry in intense radiation fields

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Mattias Jönsson; [2010]
    Keywords : Radioekologi; Medicine and Health Sciences;

    Abstract : The aim of this master thesis was to develop a rotation-based collimation system for large coaxial high-purity germanium detectors for use in intense radiation fields. A collimator was constructedformed as a cylinder surrounding the detector, with a 90° slit opening to the detector. READ MORE

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

    University essay from Institutionen för fysik, kemi och biologi

    Author : Sandberg Olof; [2010]
    Keywords : fibrinogen; albumin; IgG; bisphosphonate; antibiotic; local drug delivery;

    Abstract : 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. READ MORE

  5. 29. Using the LaBr3Ce scintillation detector for mobile gamma-spectrometry

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Jonas Nilsson; [2010]
    Keywords : Radioekologi; Medicine and Health Sciences;

    Abstract : When doing mobile gamma-spectrometry the equipment has for severaldecades been limited to NaI(Tl) and Ge-based detectors. Recent developements has led to a possible replacement of NaI(Tl)-based systems in the form of a new scintillation material: LaBr3:Ce (cerium doped lanthanum bromide). READ MORE

  6. 30. Local Delivery of Bisphosphonates from FibMat Matrix

    University essay from Institutionen för fysik, kemi och biologi

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

    Abstract : 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). READ MORE
