1. 11. Datorträning i läsflyt och stavning : analys och utvärdering av fixerad och resultatstyrd flash-cardexponering

   Författare :Maj-Gun Johansson; Åke Olofsson; Pekka Niemi; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Reading fluency; automatization; flashcard training; time pressured exposure; computer-based remediation; dyslexia; decoding strategy; orthographic coding; phonological decoding; Psychology; Psykologi; Psychology; psykologi; Education; pedagogik;

   Sammanfattning : During the last decade new attention has been paid to reading fluency. One reason might be that training studies often have failed to provide growth in reading rate in spite of the fact that the accuracy problem was remediated. LÄS MER

3. 12. Learning text talk online : Collaborative learning in asynchronous text based discussion forums

   Författare :Monica Liljeström; Agneta Hult; Anders. D. Olofsson; Lars Svensson; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Online learning; CSCL; online assessment; collaborative learning; peer assessment; peer review; folkbildning; Swedish liberal adult education online; higher education online; socio-cultural theory; asynchronous discussion forums; ADF; evaluation;

   Sammanfattning : The desire to translate constructivist and sociocultural approaches to learning in specific learning activities is evident in most forms of training at current, not least in online education. Teachers worldwide are struggling with questions of how to create conditions in this fairly new realm of education for learners to contribute to the development of a good quality in their own and others' learning.

4. 13. The zone concept : design of low-voltage installations considering the spread of high frequency harmonics

   Författare :Martin Lundmark; Magnus Olofsson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Power Engineering; Elkraftteknik; Energy Engineering; Energiteknik;

   Sammanfattning : The use of electric power has become a backbone of the modern society. Together with the growth in possible applications of electric power, we also see a growth in the number of devices and the interest of using electrical energy as an environmentally-friendly alternative to other sources of energy.

5. 14. On the running-in of gears

   Författare :Sören Sjöberg; Ulf Olofsson; Anders Flodin; KTH; []
   Nyckelord :gears; gear manufacturing; running-in; surface topography; contact area ratio; manganese phosphate; Mechanical engineering; Maskinteknik;

   Sammanfattning : The general trend in gear industry, today, is an increased focus on gear transmission efficiency. Gear transmission efficiency losses arise from loaded and unloaded gear contacts, seals, lubricant and bearings. One way of minimising the losses is to lower the lubricant viscosity. This will reduce the speed dependent losses. LÄS MER

7. 15. The Effect of Snow on Plants and Their Interactions with Herbivores

   Författare :Mikaela Torp; Johan Olofsson; Christa Mulder; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Snow; arctic ecosystem; plant-herbivore interactions; phenology; nitrogen; phenolics; experimental manipulation; natural gradient; inter-annual variability; Biology; Biologi;

   Sammanfattning : The ongoing climate changes are predicted to accelerate fast in arctic regions with increases in both temperatures and precipitation. Although the duration of snow cover is generally expected to decrease in the future, snow depth may paradoxically increase in those areas where a large amount of the elevated precipitation will fall as snow.
