1. 1. Framing and Overflowing : How the Infusion of Information Technology Alters Proximal Service Production

   Författare :Sara Värlander; Ali Yakhlef; Mats Edenius; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Services marketing; physical-virtual interplay; framing; overflowing; Internet; service production; face-to-face; co-presence; incorporation; inscription; participation; reification; Business studies; Företagsekonomi; Business Administration; företagsekonomi;

   Sammanfattning : In the heyday of the Internet, there was a wide-spread, not so well grounded, euphoria about the prospects of the Internet for virtualising various service activities. However, by now, a more informed understanding is emerging. LÄS MER

3. 2. Contemporary aspects of health and performance among young adult women and men in Sweden

   Författare :Jesper Löve; Göteborgs universitet; []
   Nyckelord :stress; young adults; gender; work ability; performance; sickness presenteeism; individualization; grounded theory; anxiety; womens health; modern society; health; well-being;

   Sammanfattning : The overall aim of this thesis was to improve our understanding of contemporary aspects of health and performance among young adult women and men in Sweden. Cultural and structural changes in society have resulted in new environmental conditions, which in turn give rise to new potential health hazards. LÄS MER

4. 3. Simulating the palaeorecord of northern European lakes using a coupled lake-catchment model

   Författare :Jüri Vassiljev; Kvartärgeologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climatology; cartography; pedology; geomorphology; Physical geography; northern Europe; catchment geometry; Holocene; overflow lakes; climate change; Water- and energy-balance modelling; lake-level changes; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

   Sammanfattning : A coupled lake-catchment model was developed to examine the controls on lake-level changes in currently overflowing lakes during Holocene. The lake energy-balance is simulated as the one-dimensional vertical heat transfer by eddy diffusion and convective mixing. LÄS MER

5. 4. Cold lap formation in Gas Metal Arc Welding of steel : An experimental study of micro-lack of fusion defects

   Författare :Peigang Li; Lars-Erik Svensson; Norbert Enzinger; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tandem GMAW; old laps; lack of fusion; Spatter; Overlap; Overflow; Manganese; Silicon; Oxides; Temperature; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Cold laps are defined as micro-lack of fusion defects at the weld toe more or less parallel to the surface of the parent plate. These defects are known to negatively influence the fatigue properties of weldments. Previous studies suggest that cold lap formation can not be avoided completely in Gas Metal Arc Welding (GMAW).
