    Abstract : Popular Abstract in Swedish Det blir allt vanligare att man ersätter förlorade och skadade kroppsdelar med ett biomaterial (vanligtvis ett metall eller polymer implantat). Exempel på vanliga användningsområden är; suturer, kärl, hjärtklaffar, pacemakers, katetrar, ledproteser, fixationsskruvar för skelett och konstgjorda tänder samt kapslar för långsam frisättning av medicin.

    Abstract : Degradable polymers have gained an increased attention in the field of biomedical applications over the past decades, for example in tissue engineering. One way of improving the biocompatibility of these polymers is by chemical surface modification, however the risk of degradation during the modification procedure is a limiting factor. READ MORE

  4. 4. Adhesion and Friction - a Study on Tactility

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Kenneth Duvefelt; KTH.; [2016]
    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

  5. 5. Biological growth on rendered façades

    University dissertation from Lund University, Division of Building Materials

    Author : Sanne Johansson; Lunds universitet.; Lund University.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temperature; render; radiation; photosynthesis; moulds; mosses; mortar; moisture; lichens; Imaging-PAM; humidity; heat capacity; heat; ETICS; algae; biological growth; calorimetry; desiccation tolerance;

    Abstract : Popular Abstract in Swedish Biologiska organismer har en fantastisk förmåga att anpassa sig till alla möjliga miljöer. Människans aktiviteter på jorden har skapat många nya habitat för olika typer av organismer; t ex kan vissa organismer växa på sten och vertikala klippor och när människor bygger hus så kan dessa organismer flytta över till väggar och tak som blir nya biotoper att leva på.
