  2. 1. Proton pathways in energy conversion : K-pathway analogs in O2- and NO-reductases

    Author : Nathalie Gonska; Pia Ädelroth; Alessandro Giuffré; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heme-copper oxidase; cytochrome c oxidase; membrane protein; respiration; electron transfer; proton transfer; redox reaction; metalloprotein; non-heme iron; cytochrome ba3; flow-flash; carbon monoxide; liposome; respiratory control ratio; Biochemistry; biokemi;

    Abstract : Oxygen and nitric oxide reductases are enzymes found in aerobic and anaerobic respiration, respectively. Both enzyme groups belong to the superfamily of Heme-Copper Oxidases, which is further divided into several subgroups: oxygen-reducing enzymes into A-, B- and C-type and nitric oxide reductases into qNORs and cNORs.

  4. 2. On boundary value problems for intracellular subdiffusion and signaling pathways, and for geometric flows

    Author : Tobias Gebäck; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; boundary value problems; diffusion-reaction equations; signaling pathways; anomalous diffusion; pseudo-differential equations; fluorescence correlation spectroscopy; immersed interface method; Boolean grids; mean curvature flow; pseudo-differential equations; boundary value problams; flourescence correlation spectroscopy;

    Abstract : The main part of this thesis concerns mathematical models for diffusion of proteins inside cells, including reactions between the proteins. Initially, such models are applied to describe signaling pathways in yeast cells, and the properties of the model are studied, especially in relation to models that do not include diffusion.

  5. 3. Surface tension-driven flow in soft porous materials — An investigation of the mechanism of capillary flow in microchannels of hydrogels

    Author : Johanna Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wetting on soft materials; Capillary flow; alginate gel; capillary action;

    Abstract : Spontaneous spreading of liquids in porous materials is of great industrial relevance and occurs in, for example, diapers, fabrics, paper or paint. Often, it is necessary to manipulate the spreading rate of liquids to result in the desired mass transport, for example to soak up large liquid volumes, as in a diaper. READ MORE

  6. 4. Evaluation of Biological Biomaterial Properties using Microfluidic Systems

    Author : Abdul Raouf Atif; Gemma Mestres; Séverine Le Gac; Uppsala universitet; []
    Keywords : Bone; Flow; Hydroxyapatite; In vitro; Modelling; On-chip; PDMS; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Abstract : Despite increased orthopedic biomaterial research activity over previous decades, relatively few novel biomaterials have made it to clinical use. This may partially be due to the inability of existing in vitro testing routines to sufficiently replicate the physiological environment, leading to potentially inaccurate assessments of a biomaterial’s therapeutic potential.

  7. 5. Mitigating Microplastics Pollution in Urban Water Systems : Flow, actors, and control measures

    Author : Emma Fältström; Stefan Anderberg; Annica Carlsson; Hamse Kjerstadius; Lian Lundy; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Municipalities; Plastic; Pollutants; Preventive measures; Stormwater; Wastewater; Water treatment;

    Abstract : Water pollution has long been considered a challenge in urban areas. Urban wastewater and stormwater act as transport pathways for pollutants from urban areas to receiving waters. Microplastics are a pollution problem of growing concern. READ MORE
