1. Towards energy efficient protocols for active RFID
Sammanfattning : The absence of a global standard is a bottleneck when using Radio Frequency Identification (RFID) technology. This thesis explores data communication protocols for Active-RFID regarding their energy efficiency and how they can be suited to fit a large variety of applications. LÄS MER
2. Energy Efficient Protocols for Active RFID
Sammanfattning : Radio frequency identification (RFID) systems come in different flavours; passive, active, semi-passive, or semi-active. Those different types of RFID are supported by different, internationally accepted protocol standards as well as by several accepted proprietary protocols. LÄS MER
3. Improving selectivity in protein extraction by subtle interactions and environmental changes
Sammanfattning : The challenges for efficient bioprocesses lie in developing and adapting further current technologies or in creating innovative separation technologies. The thesis is based on the studies on protein recovery from crude feedstocks by extraction in aqueous two-phase systems and detergent foam, respectively. LÄS MER
4. Glycoside hydrolases from extremophiles isolated in Iceland. alpha-L-Rhamnosidases and pectin degrading enzymes
Sammanfattning : Extreme environments (high and low temperature, high and low pH, etc.) are inhabited by a vast and diverse flora of microorganisms, which are adapted to these environments (extremophiles). LÄS MER
5. Development of a Sel-tag for multimodality imaging and studies of mammalian thioredoxin reductase 1
Sammanfattning : Selenocysteine (Sec; U in one-letter code), the 21st amino acid existing in all selenoproteins, has unique biochemical properties due to its selenium atom, including a low pKa and a high reactivity with many electrophilic agents. When a selenoprotein is translated, the insertion of Sec occurs at a UGA codon, normally yielding translational termination. LÄS MER
