1. 21. Life-Cycle Energy and Carbon Implications of Wood-Based Products and Construction

   Författare :Roger Sathre; Leif Gustavsson; Birger Solberg; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest products; climate change mitigation; carbon balance; energy; life cycle; wood; land use; Environmental engineering; Miljöteknik;

   Sammanfattning : Forests can be an important element of an overall strategy to limit the atmospheric concentration of carbon dioxide (CO2) that contributes to climate change. As an integral part of the global carbon cycle, forests remove CO2 from the atmosphere as they grow, and accumulate carbon in tree biomass. LÄS MER

3. 22. 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

4. 23. Product Information Quality : A sustainability challenge in design and construction

   Författare :Soheila Bahrami; Avdelningen för Byggproduktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Standardization; sustanability; Product information; Building design; industrialized construction;

   Sammanfattning : The adverse consequences of building product performance pose sustainability problems for the built environment. Effective approaches to these problems require a clear understanding of building product information and its provision by manufacturers. LÄS MER

5. 24. Multifunctional nanostructured Ti-Si-C thin films

   Författare :Per Eklund; Lars Hultman; Hans Högberg; G. Ramanath; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material physics with surface physics; Materialfysik med ytfysik;

   Sammanfattning : In this Thesis, I have investigated multifunctional nanostructured Ti-Si-C thin films synthesized by magnetron sputtering in the substrate-temperature range from room temperature to 900 °C. The studies cover high-temperature growth of Ti3SiC2 and Ti4SiC3, low-temperature growth of Ti-Si-C nanocomposites, and Ti-Si-C-based multi¬layers, as well as their electrical, mechanical, and thermal-stability properties.

7. 25. On the Determination of Reactive Compounds in Aerosols

   Författare :Mårten Spanne; Ergonomi och aerosolteknologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; industrial hygiene; isocyanates; particles; sampling; aerosols; pollution control; Miljöteknik; kontroll av utsläpp;

   Sammanfattning : Many sources of airborne contaminants have always been present in various work environments. With the development of thermosetting plastic systems, the use of reactive chemical compounds was greatly increased and thus also the risk of exposure to reactive and potentially hazardous compounds.
