2. 1. Surface Force and Friction : effects of adsorbed layers and surface topography

   Author : Xiaoyan Liu; Per Claesson; Bjorn Torger Stokke; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Friction; nanotribology; surface forces; diblock copolymer; lipid; QCM-D; AFM; optical reflectometry; neutron reflectivity; X-ray reflectivity; micro-patterned surface; Kemi; Chemistry;

   Abstract : Interfacial features of polymers are a complex, fascinating topic, and industrially very important. There is clearly a need to understand interactions between polymer layers as they can be used for controlling surface properties, colloidal stability and lubrication. The aim of my Ph. READ MORE

   Abstract : Modern radiotherapy aims to treat the decease while minimizing the radiation dose to the adjacent normal tissue, to minimize acute and late effects of the treatment. The foremost technological approaches have been intensity modulated radiotherapy (IMRT) and intensity modulated proton therapy (IMPT) in combination with image guided radiotherapy (IGRT). READ MORE

5. 3. On Surface Topography of Cylinder Liners

   Author : Zlate Dimkovski; John Westberg; Högskolan i Halmstad; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cylinder liner; Surface Roughness; Characterisation; Honing; Wear; Blechmantel; Groove Parameters; Quality Control; Flow Simulation; Surface engineering; Ytbehandlingsteknik;

   Abstract : The frictional losses, oil consumption and emissions in internal combustion engines are in great extent controlled by the cylinder liner surface topography. This emphasises the importance of: investigating the liner’s topography by objectively characterising it, investigating its effects on the tribological function to gain a better understanding and improving its manufacturing.

   Abstract : With increasing environmental awareness, the desire to protect human beings and the environment from adverse effects induced by dispersed metals has become an issue of great concern and interest. New policies, such as REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) within the European Community, have been implemented to reduce hazards posed by the use of chemicals on producers and downstream users.

   Abstract : Behandling med käkbensförankrade tandimplantat är en vanlig metod för att ersätta förlorade tänder hos helt och partiellt tandlösa patienter. Trots att implantatbehandling uppvisar en långsiktigt hög lyckande- och överlevnadsfrekvens (90–95% efter 10 år) så förekommer implantatförluster och marginal benförlust kring implantaten under det första året efter insättning och/eller belastning, vilket kan försämra det estetiska resultatet.
