1. 36. An Experimental Investigation of a Prototype Kaplan Turbine and Numerical Analysis of Fluid Added Parameters on the Corresponding Model Turbine Runner

   Författare :Arash Soltani Dehkharqani; Michel Cervantes; Francesc Xavier Escaler Puigoriol; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Sammanfattning : Among the renewable energy sources, hydropower plays an important role by providing approximately 60% of the renewable electricity. Globally, there is a growing installed capacity of renewable energy sources. LÄS MER

3. 37. From health to e-health : understanding citizens' acceptance of online health care

   Författare :Marie-Louise Jung; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Industriell marknadsföring; Industrial Marketing;

   Sammanfattning : In light of the challenges arising from an ageing population and runaway health-care costs, e-health offers tremendous opportunities for public and private health-care providers worldwide to optimize service delivery and enhance the quality of care being provided to patients. Even though the potential of e-health is acknowledged in academia as well as among practitioners, its application has proven to be remarkably difficult. LÄS MER

4. 38. Modelling drivers of energy demand in the European Union building sector

   Författare :Eoin Ó Broin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EU; Elasticities; Heating; Policy; Bottom-up; Top-down; Efficiency; Residential;

   Sammanfattning : In the context of ongoing initiatives within the European Union (EU) to tackle global warming and to secure future energy supplies, the building sector is often cited as offering strong potential for energy savings. The primary aims of this thesis are to analyse the historical data related to EU building and to generate scenarios that highlight the technical and non-technical parameters that affect the energy demands (and thereby the potentials for savings) of the building sector.

5. 39. Magnetohydrodynamics of Turbulent Accretion Disks and Planet Formation

   Författare :Wladimir Lyra; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy and astrophysics; Astronomi och astrofysik;

   Sammanfattning : Planets have long been believed to form in disks of gas and dust around youngstars, interacting with their surroundings via a setof complex and highly nonlinear processes. In the core accretion scenario forgiant planet formation dust coagulates first into km-sized icyand rocky planetesimals that further collide, formingprogressively larger solid bodies that eventually give rise to cores of severalEarth masses.

7. 40. Bio-coal for the sustainable industry : A scientific approach to optimizing production, storage, and usages

   Författare :Aekjuthon Phounglamcheik; Kentaro Umeki; Markus Broström; Capucine Dupont; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

   Sammanfattning : Bio-coal produced from biomass is a promising material to replace fossil coal in order to achieve net-zero greenhouse gas emission from the industrial sector. Bio-coal with quality comparable to that of fossil coal can be produced by high-temperature pyrolysis at ≥500 ºC, but the production efficiency is relatively low due to low bio-coal yield at high pyrolysis temperatures.
