2. 1. Life Cycle Thinking in Environmentally Preferable Procurement

   Author : Elisabeth Hochschorner; Göran Finnveden; Anna Björklund; Ann-Marie Tillman; KTH; []
   Keywords : Life Cycle Thinking; Life Cycle Assessment; Environmental Procurement; Life Cycle Costing; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Products generate environmental impacts during their life cycle by consuming raw materials and energy, releasing emissions and producing waste. A procurement organisation can be a considerable driving force for more environmentally friendly products e.g. by requiring that products meet certain environmental criteria. READ MORE

4. 2. Roller skis' rolling resistance and grip characteristics : influences on physiological and performance measures in cross-country skiers

   Author : Mats Ainegren; Peter Carlsson; Marko Laaksonen; Mittuniversitetet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adjustable grip; blood lactate; centre of pressure; cycle length; cycle rate; economy; efficiency; friction coefficient; heart rate; normal force; OBLA; oxygen uptake; power; ratcheted wheel; ratings of perceived exertion; roller skis; rolling resistance; tangential force; time to exhaustion;

   Abstract : The aim of this thesis was to investigate roller ski characteristics; classical and freestyle roller skis’ rolling resistance coefficients (μR) and classical style roller skis’ static friction coefficients (μS), and to study the influence of different μR and μS on cross-country skiers’ performance and both physiological and biomechanical indices. The aim was also to study differences in skiing economy and efficiency between recreational skiers, female and male junior and senior elite cross-country skiers. READ MORE

5. 3. Life cycle assessment in the development of forest products : Contributions to improved methods and practices

   Author : Gustav Sandin; Magdalena Svanström; Greg Peters; Mats Westin; Annica Pilgård; Michael Narodoslawsky; RISE; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; R D; LCA; Life cycle assessment; wood; forest product; forestry; impact assessment; scenario modelling; end-of-life modelling; allocation; multi-functional; planetary boundaries; life cycle inventory; life cycle impact assessment; environmental assessment;

   Abstract : The prospect of reducing environmental impacts is a key driver for the research and development (R&D) of new forest products. Life cycle assessment (LCA) is often used for assessing the environmental impact of such products, e.g. for the purpose of guiding R&D. READ MORE

6. 4. Integrated Life Cycle Design - Applied to concrete multi-dwelling buildings

   Author : Mats Öberg; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; livslängd; materialval; energianvändning; inomhusklimat; livscykelanalyser; livscykelkostnader; hållbar utveckling; Sustainable construction; Building construction; Service life design; Multiple Attribute Decision Analysis; Energy efficient buildings; Life Cycle Assessment; projektering; betongkonstruktioner; flerbostadshus; Byggnadsteknik; Integrated life cycle design; Life Cycle Costing;

   Abstract : The objective of this work is to explore ways of enhancing the overall lifetime quality, including cost and environmental efficiency, of Swedish concrete multi-dwelling buildings. The building and its characteristics, as well as the procedures for whole life optimisation, are addressed. READ MORE

7. 5. Single-cycle undulator light

   Author : Georgii Shamuilov; Vitaliy Goryashko; Gianluca Geloni; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; terahertz technology; light sources; electron beams; space charge; waveform control; optical magnetic lens; Fysik; Physics;

   Abstract : The past decade has witnessed a sharp rise of interest in coherent terahertz (THz) light sources for applications in condensed-matter physics. These sources are a powerful tool for studying collective excitations in solid-state systems: THz light can directly couple to low-energy excitations on the meV-scale such as the collective excitations of spins and phonons.
