2. 21. Influence of waxes on bitumen and asphalt concrete mixture performance

   Author : Ylva Edwards; Ulf Isacsson; Klaus-Werner Damm; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bitumen; asphalt; additives; wax in bitumen; polyphosphoric acid in bitumen; rheology; IR-spectroscopy; dynamic mechanic analysis DMA ; bending beam rheometer BBR ; literature study; low temperature physical hardening; highway materials; morphology; modified bitumens; temperature susceptibility; low temperature performance; ageing; microscopy; chromatography; Fourier transform infrared spectroscopy; force ductility; conventional binder tests; asphalt performance; tensile strain restrained specimen test TSRST ; Building engineering; Byggnadsteknik;

   Abstract : This doctoral thesis consists of a literature review, presented in two papers, and another six papers describing experimental studies of the influence of different kinds of wax and polyphosporic acid on bitumen and asphalt concrete mixture properties. The literature review should give an extensive description of the field of knowledge concerning wax in bitumen. READ MORE

5. 23. Aspects on Function in Age-Related Macular Degeneration

   Author : Christina Winther; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; age-related macular degeneration; macula; macular oedema; rarebit; reading test; reading speed; self-test; smartphone application; vision test; visual acuity;

   Abstract : Age-related macular degeneration (AMD) is one of the leading causes of severe visual loss among persons ≥ 60 years. AMD can be categorized in one of three stages: early, intermediate, or late. In early AMD visual symptoms are inconspicuous whereas, in the late stage, severe loss of vision is common. Late AMD has dry and wet forms. READ MORE

6. 24. Performance Indicators. A performance prediction method for moisture safety design

   Author : Veronica Yverås; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Artificial Neural Network; Performance prediction; Moisture safety;

   Abstract : The aims of this research project is to develop and gain knowledge about a different approach to moisture safety design based on AI in order to attain healthy buildings and relate this new approach to current practice and prospective users. Secondary data (data produced for some other purpose) was used to train Artificial Neural Networks (ANN) to predict the performance of outdoor ventilated crawl-spaces regarding microbiological smell, mould and rot.

7. 25. Essays on Determinants of Individual Performance and Labor Market Outcomes

   Author : Olof Rosenqvist; Oskar Nordström Skans; Lena Hensvik; Ghazala Azmat; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Confidence; success; failure; performance; regression discontinuity design; golf; gender differences; glass ceiling; voting age; political knowledge; civic interest; dynamic effects; sickness absence; production disruption; coworker substitutes; hiring decisions; separations; Economics; Nationalekonomi;

   Abstract : Essay 1 (with Oskar Nordström Skans): This paper provides field evidence on the causal impact of past successes on future performances. Since persistence in success or failure is likely to be linked through, potentially time-varying, ability it is intrinsically difficult to identify the causal effect of succeeding on the probability of performing well in the future.
