1. Perfusion Monitoring of Advancement and Rotational Flaps. Oculoplastic Surgery and Laser Speckle Contrast Imaging
Sammanfattning : Flaps are widely used in oculoplastic reconstructive surgery to cover defects following the removal of tumors, malformations, or trauma. Adequate blood perfusion of the flap is crucial for its survival. Knowledge about the perfusion in different type of flaps is therefore of great value. LÄS MER
2. Dynamics and Reactivity of Cu-species in Cu-CHA for NH3-SCR
Sammanfattning : Copper exchanged chabazite (Cu-CHA) is a state-of-the-art catalyst for deNOx via ammonia assisted selective catalytic reduction (NH3-SCR) in lean burn engines, owing to its good low-temperature activity, and high hydrothermal stability. One challenge for Cu-CHA is, however, the sensitivity to sulfur species, which are present in the exhaust gas. LÄS MER
3. Fate of Cu, Cr, As and some other trace elements during combustion of recovered waste fuels
Sammanfattning : The increased use of biomass and recovered waste fuels in favor of fossil fuels for heat and power production is an important step towards a sustainable future. Combustion of waste fuels also offers several advantages over traditional landfilling, such as substantial volume reduction, detoxification of pathological wastes, and reduction of toxic leaches and greenhouse gas (methane) formation from landfills.

4. On the reaction mechanism for selective catalytic reduction of NOx by NH3 over Cu-zeolites
Sammanfattning : Nitrogen oxides (NOx) are major pollutants from combustion processes, being corrosive and hazardous to human health. The main technology for exhaust aftertreatment of NOx emitted from diesel engines is selective catalytic reduction with ammonia as reducing agent (NH3-SCR). LÄS MER
5. Engineering Yeast for Functional Analysis of Human Cu Transport Proteins
Sammanfattning : ABSTRACT Copper (Cu) is an important trace element that plays a vital role in several biological processes. Many proteins that are involved in various biochemical pathways require Cu as a cofactor. LÄS MER
