    Abstract : In recent decades, Rwanda has been affected by the loss and fragmentation of natural habitats for native species of animals and plants. As a consequence, landscape connectivity—i.e. READ MORE

  4. 2. Hydrophobic Interactions in Bioseparation - Applications of Modified Green Fluorescent Protein

    Author : Kristian Becker; Tillämpad biokemi; []
    Keywords : Hydrophobic interaction chromatography; capillary electrochromatography; E. coli; isolation tags; haemoglobin; green fluorescent protein; retention prediction; genetic engineering; accessible surface area;

    Abstract : This thesis describes interactions that are salt-promoted and mainly based on the hydrophobicity of proteins. A series of variants of the green fluorescent protein (GFP) was first constructed by site-directed mutagenesis. Several tags with various properties were then genetically fused to the N-terminus of GFP. READ MORE

  5. 3. Applications of Structural Bioinformatics for the Structural Genomics Era

    Author : Marian Novotny; Gerard Kleywegt; Geoff Barton; Uppsala universitet; []
    Keywords : Bioinformatics; structural bioinformatics; fold comparison; left-handed helix; docking; solvent-accessible surface area; register shift; X-ray crystallography; Bioinformatik;

    Abstract : Structural bioinformatics deals with the analysis, classification and prediction of three-dimensional structures of biomacromolecules. It is becoming increasingly important as the number of structures is growing rapidly. READ MORE

  6. 4. On the Mechanism of Assembly of Xylans onto Cellulose Surfaces

    Author : Åsa Linder; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aggregation; Xylan; cellulose; surface structures; assembly;

    Abstract : Cellulose is the most abundant biopolymer on earth and the major component in cell walls of wood and terrestrial plants. Commercial applications include paper, plastics, hygiene and pharmaceutical products. The composition and morphology of cellulose surfaces affect the product properties. READ MORE

  7. 5. Investigation of electrochemical properties and performance of stimulation/sensing electrodes for pacemaker applications

    Author : Anna Norlin; Jinshan Pan; Dieter Scharnweber; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; pacemaker electrode; interfacial property; biomaterial; electrostimulation charge transfer mechanism; electrochemical impedance spectroscopy; transient processes; plasma electrolysis anodisation; porous niobium oxide; ruthenium oxide; nano-porous carbon; iridium oxide; titanium nitride; platinum; surface roughness; porous electrode; pacing impedance; electrode polarisation; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

    Abstract : People suffering from certain types of arrhythmia may benefit from the implantation of a cardiac pacemaker. Pacemakers artificially stimulate the heart by applying short electrical pulses to the cardiac tissue to restore and maintain a steady heart rhythm. By adjusting the pulse delivery rate the heart is stimulated to beat at desired pace. READ MORE
