4. 17. Towards a Better Understanding and Control of Factors Affecting the Physical Quality of Fish Feed

   Author : Julia Wolska; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fish Feed; Physical quality; Durability; Aging; Crosslinking; Transglutaminase;

   Abstract : As aquaculture expands, the volume of fish feed produced and transported must also increase. Therefore a better understanding and increased control of the factors that influence the physical quality of feed pellets is required. To achieve this goal, reliable methods measuring the physical quality of feed are needed. READ MORE

5. 18. Traditional lime mortar and plaster : Reconstruction with emphasis on durability

   Author : Kristin Balksten; Tor Broström; Britt-Marie Steenari; Thorborg Konow von; Chalmers Tekniska Högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lime plaster; lime mortar; masonry; craftsmanship; pore structure; frost resistance; historic mortar; Conservation HGO ; Kulturvård HGO ;

   Abstract : Lime mortar and plaster have been investigated with the aim to improve the knowledge on how to make them as durable as before the cement technology was developed. The background was the durability problems experienced for newly produced lime plaster on the medieval churches on the island of Gotland, Sweden. READ MORE

6. 19. Aerogel-based plasters for renovation of buildings in Sweden: Identification of possibilities, information deficiencies and challenges

   Author : Ali Naman Karim; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compatibility; durability; plaster; mechanical; render; energy efficient retrofitting; hygrothermal; renovation; listed building; Aerogel;

   Abstract : Aerogel-based plasters are a class of high energy efficient wall finishes with declared thermal conductivities around 30-50 mW/(m∙K). Aerogel-based plasters are promising alternatives to substitute conventional insulation materials when renovating uninsulated building envelopes. READ MORE

7. 20. Calcium aluminate cement as dental restorative : Mechanical properties and clinical durability

   Author : Karin Sunnegårdh-Grönberg; Jan van Dijken; Preben Hørsted Bindslev; Umeå universitet; []
   Keywords : mechanical properties; clinical; restorations; ceramic; cement; resin composite; adaptation; SEM; odontologi; Odontology;

   Abstract : In 1995, the Swedish government recommended the discontinuation of amalgam as restorative in paediatric dentistry. Because the mercury content in amalgam constitutes an environmental hazard, its use has declined. READ MORE
