36. Modeling the Microstructural Evolution during Hot Deformation of Microalloyed Steels
Sammanfattning : This thesis contains the development of a physically-based model describing the microstructural evolution during hot deformation of microalloyed steels. The work is mainly focused on the recrystallization kinetics. During hot rolling, the repeated deformation and recrystallization provides progressively refined recrystallized grains. LÄS MER
37. Modeling the microstructural evolution during hot working of C-Mn and of Nb microalloyed steels using a physically based model
Sammanfattning : Recrystallization kinetics, during and after hot deformation, has been investigated for decades. From these investigations several equations have been derived for describing it. The equations are often empirical or semi-empirical, i.e. LÄS MER
38. Recovery of Scandium using Antisolvent Crystallization in the Valorization of Scandium-containing Waste Streams
Sammanfattning : Scandium is widely dispersed in the earth’s crust and is rarely concentrated in ores, and a viable option to guarantee a secure supply of scandium is to recover the metal from waste streams of other mining and metallurgical facilities. The valorization of such streams to recover metals of value is a prerequisite to alleviate the global shortages of scandium and other rare earth elements. LÄS MER
39. Aspects of the ATLAS ITk Inner Tracker development for the high luminosity upgrade of the Large Hadron Collider
Sammanfattning : The High Luminosity upgrade of the Large Hadron Collider (HL-LHC), necessitates that the ATLAS experiment replace their current Inner Detector (ID) system. The new Inner Tracker (ITk) will be an all silicon detector, utilising both pixel and strip sensors, with the aim of performing as well, or better than the current system - but in a much more challenging environment.

40. Dynamic principles in craniofacial surgery. Expander elements in craniofacial surgery
Sammanfattning : Lannelongue & Lane described strip removal of ossified skull sutures in craniosynostosis in the 1890s. More complex osteotomies with bone grafting were developed during the 1960s. Dynamic techniques, utilizing force to direct the growing brain for skull reshaping was introduced by Jane 1978 with the p-plasty for sagittal synostosis. LÄS MER
