  2. 1. Perfusion Monitoring of Advancement and Rotational Flaps. Oculoplastic Surgery and Laser Speckle Contrast Imaging

    Author : Cu Dybelius Ansson; Lund Oftalmologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; flap; eyelid; oculoplastic; diathermic coagulation; laser speckle contrast imaging; perfusion; flap; eyelid; oculoplastic; diathermic coagulation; laser speckle contrast imaging;

    Abstract : 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. READ MORE

  4. 2. Dynamics and Reactivity of Cu-species in Cu-CHA for NH3-SCR

    Author : Joachim Bjerregaard; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Machine Learning Force Field; Diffusion; Cu-CHA; NH3-SCR; DFT; Sulfur Deactivation;

    Abstract : 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. READ MORE

  5. 3. Fate of Cu, Cr, As and some other trace elements during combustion of recovered waste fuels

    Author : Karin Lundholm; Anders Nordin; Britt-Marie Steenari; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; combustion; chemical equilibrium model calculations; trace elements; impregnated wood; waste; thermodynamic data; Cu; Cr; As; Other chemistry; Övrig kemi;

    Abstract : 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.

  6. 4. On the reaction mechanism for selective catalytic reduction of NOx by NH3 over Cu-zeolites

    Author : Lin Chen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DFT; O2-activation; Cu-SSZ-13; NH3-SCR; Cu-CHA; Al-distribution;

    Abstract : 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). READ MORE

  7. 5. Engineering Yeast for Functional Analysis of Human Cu Transport Proteins

    Author : Kumaravel Ponnandai Schanmugavel; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cu transport; yeast model; Atox1; genetic engineering; Wilson disease protein; ATP7B; complementation assay; yeast growth; metal-binding domain; mechanisms.;

    Abstract : 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. READ MORE
