1. 21. Seeing What Is Not There : Essays on Pictures and Photographs

   Författare :Mikael Pettersson; Staffan Carlshamre; Göran Rossholm; Robert Hopkins; Stockholms universitet; []
   Nyckelord :depiction; photography; pictorial experience; perception; phenomenology; Theoretical Philosophy; teoretisk filosofi;

   Sammanfattning : Pictures—paintings, etchings, photographs, CGI—let us see what is not there. Or, rather, since what pictures depict is not really there, we do not really see the pictorial contents. But we seem to see the depicted things: we “see” them “in” the pictures. LÄS MER

3. 22. Star Formation and feedback at key physical scales for galaxy evolution

   Författare :Lorenza Della Bruna; Angela Adamo; Göran Östlin; Monica Relaño Pastor; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Galaxies; Star Formation; Stellar Feedback; HII regions; ISM; Astronomy; astronomi;

   Sammanfattning : Feedback from young, massive stars plays an essential role in the self-regulation of star formation in galaxies, and in shaping the galaxies' global properties. This phenomenon originates at small scales, surrounding the stars, but has been observed to be effective up to galactic-wide scales. LÄS MER

4. 23. Spectral modeling of nebular-phase supernovae

   Författare :Anders Jerkstrand; Claes Fransson; Luc Dessart; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; supernovae; nucleosynthesis; radiative transfer; massive stars; 1987A; IIP; supernovor; nukleosyntes; spektralmodellering; strålningstransport; massiva stjärnor; 1987A; IIP; Astronomy; astronomi;

   Sammanfattning : Massive stars live fast and die young. They shine furiously for a few million years, during which time they synthesize most of the heavy elements in the universe in their cores. They end by blowing themselves up in a powerful explosion known as a supernova (SN). LÄS MER

5. 24. Structural impact on some physical properties of cellulose-based films

   Författare :Malin Nejström; Magnus Norgren; Håkan Edlund; Ida Svanedal; Bo Andreasson; Lars Evenäs; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Cellulose is a natural material that can be used both in its original form and as a building block for creating new types of materials. This work focused on regenerated cellulose (RC) and cellulose acetate butyrate (CAB) in which the hydroxyls on the cellulose backbone were substituted with ester groups. LÄS MER

7. 25. Laser metal fusion and deposition using wire feedstock : Process modelling and CFD simulation

   Författare :Seyyed Mohammad Ali Noori Rahim Abadi; Isabelle Choquet; Fredrik Sikström; Norbert Enzinger; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Directed Energy Deposition with wire; Beam shaping; Absorptivity; Conduction-mode; Free surface deformation; Computational Fluid Dynamics; OpenFOAM.; Riktad energideponering med svetstråd; Stråformning; Absorption; Svetsning; Ytdeformation; Beräkningsströmningsdynamik; OpenFOAM.; Production Technology; Produktionsteknik;

   Sammanfattning : Laser metal fusion is widely used in production technology to manufacture parts, as in welding, cladding, and additive manufacturing. In this study, conduction mode laser metal fusion is applied without and with metal deposition from a wire feedstock. LÄS MER
