  1. 1. Energy relavant materials: Investigations based on first principles

    Författare :Erna-Krisztina Delczeg-Czirjak; Levente Vitos; Peter Mohn; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Energy production, storage and efficient usage are all crucial factors for environmentally sound and sustainable future technologies. One important question concerns the refrigeration industry, where the energy efficiency of the presently used technologies is at best 40% of the theoretical Carnot limit. LÄS MER

  3. 2. Multi-Agent Mission Planning and Execution for Small Autonomous Underwater Vehicles

    Författare :Özer Özkahraman; Petter Ögren; João Tasso de Figueiredo Borges de Sousa; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Underwater vehicles; collaborative; robotics; auv; navigation; coverage; search; slam; graph-slam; communication; control barrier functions; control; swarms; caging; capture; Datalogi; Computer Science;

    Sammanfattning : Our planet is mostly covered in water, most of it still unexplored.In order to understand our environment better, oceanographers have been mapping and monitoring these waters using ship-mounted sensors and wired vehicles with limited range compared to the vastness of the oceans.

  4. 3. To reduce a ribonucleotide – Radical solutions in enzymology in form and function

    Författare :Oskar Aurelius; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ribonucleotide reductase; X-ray crystallography; Small-angle X-ray scattering; nucleotide metabolism; protein biophysics; metalloproteins; anaerobic enzymology;

    Sammanfattning : It has been more than 50 years since the enzyme system ribonucleotide reductase (RNR), catalysing the reduction of ribonucleotides to deoxyribonucleotides, was first discovered. RNR was also the first time that radical chemistry was revealed in an enzyme. LÄS MER

  5. 4. Colonisation and PAH degradation by wood-rotting fungi in contaminated soil

    Författare :Erik Andersson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; agricultural hydrology; Soil Science; Bioteknik; Biotechnology; PLFA; PAH metabolites; PAH; degradation; contaminated soil; soil; brown-rot fungi; white-rot fungi; Colonisation; fungal growth; Lantbrukshydrologi; marklära; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : Bioremediation of soils is considered a low-cost alternative to other remediation techniques. Its ability to remove a number of different pollutants has been demonstrated, relying mainly on the activities of indigenous soil bacteria. LÄS MER

  7. 5. Samhällets styrning av fastighetsindelningen : Dåtid, nutid och framtid

    Författare :Linda Sabel; Peter Ekbäck; Kauko Viitanen; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; land s division into properties; property formation; public control; suitability examination; law and economics; Sweden; fastighetsindelning; fastighetsbildning; statlig styrning; lämplighetsprövning; rättsekonomi; Sverige; Real Estate and Construction Management; Fastigheter och byggande;

    Sammanfattning : Markens indelning i fastigheter utgör en grundläggande beståndsdel i samhällsbyggandet. De krav som ställs på fastighetsindelningen får konse­kven­ser för vilka fastigheter som får bildas, registreras och ägas vilket i sin tur påverkar samhälls­utvecklingen i ett bredare perspektiv genom att ange förut­sättningarna för var människor kan bo och bedriva olika verksamheter.
