2. 21. Nursing and anaesthesia care of growing pigs

   Author : Anneli Rydén; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : The overall aim of the present thesis was to improve the welfare of animals in research by refining the perioperative nursing and anaesthesia care of growing pigs in accordance with the 3Rs, replace, reduce and refine.Forty-six pigs were trained during a 14-day acclimatisation period to accept blood and urine sampling and ultrasound examination.

4. 22. Varestraint Weldability Testing of Cast Superalloys

   Author : Sukhdeep Singh; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Varestraint; Hot Cracking; Welding; Alloy 718; Cast Superalloys; ATI® 718 PlusTM; HIP;

   Abstract : Precipitation hardened Ni- and Ni-Fe- based superalloys, used in hot structural components for aero engines, are subjected to hot cracking phenomena during manufacturing and specifically in welding. This type of cracking involves metallurgical reactions from the liquid phase in concomitance to weld restraints. READ MORE

5. 23. Robot system for flexible 3D friction stir welding

   Author : Mikael Soron; Ivan Kalaykov; Jorge F. dos Santos; Örebro universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction Stir Welding; robotics; TECHNOLOGY; TEKNIKVETENSKAP; Automatic control; Reglerteknik; Reglerteknik; Automatic Control;

   Abstract : Applying Friction Stir Welding (FSW) on complex joint geometries requires not only a machine with 3-dimesional work space capacity, but also a sound definition of the part geometry as well as knowledge about the process. Having a joining process, such as FSW, with great characteristics from both seam quality and environmental perspective, but yet only a minor presence in the manufacturing industry may be related to flexibility and cost issues.

6. 24. Potato Starch Dispersions: Structure and Rheology

   Author : Karin Svegmark; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The influence of heating, shearing and addition of amylose on the structure and rheology of potato starch dispersions has been evaluated. The methods used were dynamic viscoelastic measurements, light microscopy and transmission electron microscopy (TEM). READ MORE
