1. 11. Spritputs. Hantverklig analys av påslag och brukssammansättning

   Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Ivan Hedrén; [2017-08-28]
   Nyckelord :roughcast; coarse plaster; stucco; pebble dash; stone cladding; spritputs;

   Sammanfattning : A large number of older buildings are plastered with roughcast by hand. Since these facades have need for maintenance and repair it is important that the knowledge of the craft of roughcasting by hand is properly documented, especially considering most of plastering today is being sprayed on mechanically.

3. 12. Can planet formation explain the observed differences in the chemical composition of binary stars?

   Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Rebecca Forsberg; [2017]
   Nyckelord :binary stars; planet formation; protoplanetary disc; Physics and Astronomy;

   Sammanfattning : A suggested explanation for the observed differences in chemical abundances in binary stars has been planet formation (e.g. Tucci Maia et al. 2014). LÄS MER

4. 13. Giant planet formation around HR8799

   Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Författare :Dan Wallsby; [2017]
   Nyckelord :HR8799; Planet formation; Protoplanetary disks; Giant planets; Astronomy; Migration; Dynamics; Physics and Astronomy;

   Sammanfattning : In the thriving field of exoplanet research new discoveries are made all the time, and while most of the observed systems can be explained with classical planet formation models - some are much harder to explain. When stars form they are often surrounded by the remaining material of the nebulae they formed from. LÄS MER

5. 14. The chemical composition of hot and cold gas giants

   Kandidat-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Linn Eriksson; [2016]
   Nyckelord :Planet formation; hot Jupiter; pebble accretion; Physics and Astronomy;

   Sammanfattning : Exoplanet surveys have identified a category of giant planets that orbit very close to their host stars - the so-called hot Jupiters. The origin of such hot Jupiters is a long standing puzzle and has been closely investigated since the first discovery of such planets in 1995. LÄS MER

7. 15. The Foundations of Graph Pebbling

   Magister-uppsats, Stockholms universitet/Matematiska institutionen

   Författare :Monir Bounadi; [2015]
   Nyckelord :;

   Sammanfattning : Graph pebbling modeling started as a method for solving a combinatorialnumber theory conjecture by Erdös and Lemke. Using thismethod, Chung proved the conjecture in 1989. Since then, the literaturehas grown considerably. Several variations and possible applicationshave been discussed, in graph theory, computer science andnetwork optimization. LÄS MER
