The base of the world economic pyramid consists of 4 billion people typically earning less than 4 USD per day. This population is generally called the base of the pyramid (BoP). Much research on BoP markets focuses on motivating companies to enter these markets to create a win-win situation such that companies can gain benefits and BoP customers can satisfy their unmet or under-served needs. The r
Manufacturers and distributors of products have a crucial role in the selection and/or verification of materials for their new products. This study sought to obtain concrete knowledge on perception, experiences, and future outlook of manufacturers and distributors who have been proactive in at least one of the two areas; the increased use of recycled materials and the decreased use of hazardous su
Det är inte bara fukt, dålig ventilation eller andra tekniska faktorer, som är boven i dramat när människor upplever att de blir sjuka av innemiljön. Livssituation och livsstil kan också påverka.
The goal of the study presented in this thesis is to evaluate the advantages and drawbacks of using powder technology in the design of the iron core of small claw-pole electric motors. The use of soft magnetic composites (SMC) and compaction technology allows the creation of complex 3D iron cores. The additional dimension opens for new solutions of the electromechanical energy conversion. A claw-p
Fuel cells are electrochemical devices that directly transform chemical energy into electricity, which are promising for future energy systems, since they are energy efficient and, when hydrogen is used as fuel, there are no direct emissions of greenhouse gases. The cell performance depends strongly on the material characteristics, the operating conditions and the chemical reactions that occur ins
Att kalla vissa historiska ledargestalter hos de kanadensiska mi'kmaqindianerna "schamaner" är inte oproblematiskt. De historiska texterna från 1600-talet nedtecknades av författare som inte behärskade mi'kmaqspråket, inte var intresserade av ursprungskulturen och dessutom skrev sina berättelser i syfte att visa missionens förträfflighet. Frågan är om det är fruktbart att applicera termen på de få
