2. 1. Bacterial use of allochthonous organic carbon for respiration and growth in boreal freshwater systems

   Author : Martin Berggren; Mats Jansson; Michael L. Pace; Umeå universitet; []
   Keywords : lakes; streams; boreal; bacterial respiration; bacterial production; bacterial growth efficiency; allochthonous organic carbon; low molecular weight compounds; naturgeografi; Physical Geography;

   Abstract : Aquatic systems worldwide receive large amounts of organic carbon from terrestrial sources. This ‘allochthonous’ organic carbon (AlloOC) affects critical physical and chemical properties of freshwater ecosystems, with consequences for food web structures and exchange of greenhouse gases with the atmosphere.

4. 2. Ecosystem processes and biodiversity : theoretical studies and experiments with an aquatic model ecosystem

   Author : Jon Norberg; Michael L Pace; Stockholms universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; Systems Ecology; systemekologi;

   Abstract : Today, human enterprise has implications for all of nature, from the well being of the smallest organism, to the alteration of global biogeochemical cycles. To understand how major ecosystem processes are affected by environmental changes and decreasing biodiversity is crucial as many of natures services depend of such processes. READ MORE

5. 3. C1 Building Blocks: New Approaches for Thiomethylations and Esterification

   Author : Marcus Söderström; Luke R. Odell; Anders Karlén; Vittorio Pace; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Borontrifluoride; Dimethylsulfide; Thiomethylation; Methylthioethers; Dithioacetalation; Methyl-Dithioacetals; Friedel-Crafts; Diarylmethanes; Defluorination; Methyl-Dithioesters; Thioamides; Diazomethane; Esterification; Medicinal Chemistry; Läkemedelskemi; Medicinal Chemistry; Läkemedelskemi;

   Abstract : The thioether motif is found in numerous pharmaceuticals. The simplest form of this motif, the methyl-thioether is similarly found in many biologically active compounds and has exhibited many advantageous properties. The installation of the thiomethyl moiety can be troublesome due to the toxicity and malodor of small sulfur reagents. READ MORE

6. 4. Probing and elucidating the dynamics of virus-membrane interaction via plasma membrane mimics

   Author : Konrad Thorsteinsson; Marta Bally; Hudson Pace; Gisa Gerold; Susan Daniel; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasma membrane; supported lipid bilayer; binding kinetics; equilibrium fluctuation analysis; TIRF; FRET; norovirus; HSV; SARS-CoV-2; histo-blood group antigens; ApoE; heparan sulfate; mikrobiologi; Microbiology;

   Abstract : Virus infection is initiated by the attachment of a virion to a susceptible cell’s plasma membrane, in a highly dynamic and well-orchestrated process that encompasses various steps and engages numerous viral and cellular factors. These dynamic steps may include initial non-specific binding to ubiquitous cell-membrane ligands, diffusion across the membrane to a suitable entry site and virus engagement with various receptors and co-receptors on the cell surface.

7. 5. The pace of innovation : Patterns of innovation in the cardiac pacemaker industry

   Author : Patrik Hidefjäll; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cardiac Pacemaker; Competition; Competitive Advantage; Defibrillator; Dominant Design; Innovation; Organizational Field; Patterns of Innovation; Technical Change; Technology Cycle; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Abstract : The PhD thesis "The Pace of Innovation" addresses the questions how patterns of innovation change over time in an industry, their consequences for competition and how institutional conditions in an industry shape determinants of patterns of innovation. Patterns of innovation mainly refer to how certain regularities in the diversity, types and locus of innovation change in an industry according to a technology and industry life cycle. READ MORE
