2. 1. Adhesion and Friction - a Study on Tactility

   Author : Kenneth Duvefelt; Ulf Olofsson; Emile Van Der Heide; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesion; finger; friction; humidity; material; model; tactile friction; tactility; Machine Design; Maskinkonstruktion;

   Abstract : Although we are surrounded by hundreds of surfaces we can still distinguish them from each other simply by touch. The tactile information, interpreted by our brain and given by our fingers, is precise, but to put words to the sensation is very difficult — is it smooth, sticky or harsh? We do not only perceive surfaces differently, we also describe them in our own way. READ MORE

4. 2. Glass Ionomer Cements with Improved Bioactive and Antibacterial Properties

   Author : Song Chen; Håkan Engqvist; Wei Xia; Jie Zhou; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomaterial; glass ionomer cement; bioactivity; hydroxyapatite; monetite; calcium silicate;

   Abstract : Dental restorative cements are placed in a harsh oral environment where they are subjected to thermal shock, chemical degradation, and repeating masticatory force. The ideal restorative dental cements should have superior mechanical properties, chemical stability, aesthetic, good handling properties, biocompatibility, antibacterial properties, and preferably bioactivity.

5. 3. 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.

   Abstract : Sensors are omnipresent in our daily life. They are used in many applications ranging from the touch screen in our smartphones to more critical contexts such as pollution monitoring. READ MORE

7. 5. Self-Diffusion and Microstructure of Some Ionic Liquids in Bulk and in Confinement

   Author : Andrei Filippov; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi; Smarta maskiner och material FOI ; Smart machines and materials AERI ;

   Abstract : An ionic liquid (IL) is a salt, which usually is in the liquid state at normal temperature and pressure. The properties of ILs can be adjusted for various processes and applications by choosing different combinations of ions. Similar to other salts, ILs contain only ions with positive (cations) and negative (anions) charges in equal proportions. READ MORE
