2. 1. Applanation Resonance Tonometry for Intraocular Pressure Measurement

   Author : Per Hallberg; Olof A. Lindahl; Anders Eklund; Christina Lindén; Per Ask; Umeå universitet; []
   Keywords : Physics; Resonance; applanation; tonometry; glaucoma; Goldmann; biomechanical; Intraocular; ART; Fysik; fysik; Physics;

   Abstract : Elevated intraocular pressure (IOP) is one of the major risk factors for glaucoma. Since glaucoma is a leading cause of blindness, reliable methods for measuring the IOP are important. This doctoral dissertation presents a new method, applanation resonance tonometry (ART), for measurement of IOP. READ MORE

5. 3. Microstructure of Cermets

   Author : Per Lindahl; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermodynamic; microchemistry; N ; AP-FIM; Ti C; cutting tools; SEM; cemented carbide; TEM; sintering;

   Abstract : The microstructure of several TiC-TiN-Mo2C-WC-Co/Ni model alloys and a commercial (Ti,Ta,W,Mo)(C,N)-(Co,Ni) type cermet was studied using x-ray diffraction, optical microscopy, scanning electron microscopy, analytical electron microscopy and atom probe field ion microscopy. In addition thermodynamical calculations were made in order to understand the development of the microstructure during sintering. READ MORE

6. 4. Empirical studies of public policies within the primary school and the sickness insurance

   Author : Erica Lindahl; Per Johansson; Mårten Palme; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; empirical studies; primary school; sickness insurance; Economics; Nationalekonomi;

   Abstract : Essay 1 (with Elly-Ann Johansson) estimates the effect of attending an MA-class during grades 4-6 on students’ cognitive skills. Using a unique survey with information on students, parents and teachers, we are able to control for many factors that could otherwise bias the results. READ MORE

   Abstract : How should we understand the relationship between information and communication technology (ICT) and sustainability? Generally, it is assumed that while ICT products contribute to many environmental and social problems as they are produced and disposed of, the potential of using ICT to achieve a more sustainable society is immense. However, despite the fact that such a discourse is favored not only in the industrial but also in the political and academic spheres, we have yet to see this presumed sustainability-related potential of ICT fully exploited.
