  1. 21. Affective touch throughout life: from cortical processing in infancy to touch perception in adulthood

    Författare :Emma H. Jönsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Affective touch; Touch perception; Cortical activation; C-tactile afferents;

    Sammanfattning : Affective, interpersonal touch is important for forming and maintaining social bonds. In the hairy skin of humans there is a specific type of nerve fibers called C-tactile (CT) afferents which are optimally activated by a light stroking of the skin, like a caress. LÄS MER

    Sammanfattning : 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.

  4. 23. Mechanisms for and consequences of cellular lipid accumulation - Role of the Very Low Density Lipoprotein (VLDL) receptor

    Författare :Jeanna Perman; Göteborgs universitet; []
    Nyckelord :very low density lipoprotein receptor; lipid accumulation;

    Sammanfattning : Lipid accumulation in non adipose tissue is associated with various cases of tissue dysfunction and tissue failure. Reduced availability of oxygen is known to cause intracellular lipid accumulation in cardiomyocytes as well as in hearts. LÄS MER

  5. 24. The Effect of Various Dopants on Diamond Growth : A Combined Experimental & Theoretical Approach

    Författare :Yiming Zou; Karin Larsson; Mats Boman; Petter Persson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diamond; Growth rate; HFCVD; Doping; Activation energy; Reaction order;

    Sammanfattning : Diamond is a unique material with many exceptional properties. It has therefore been proven to be an important material for many applications. Moreover, the introduction of dopant species into the gas phase during the CVD growth process has been shown to strongly influence not only the properties and morphology of diamond, but also the growth rate.

  7. 25. Molecular Motion in Frustrated Lewis Pair Chemistry: insights from modelling

    Författare :Maoping Pu; Timofei Privalov; Todd Martinez; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CO2 capture; hydrogen activation; molecular motion; ab initio molecular dynamics; frustrated Lewis pair; quantum chemical modelling; reaction mechanism; Organic Chemistry; organisk kemi;

    Sammanfattning : Mechanisms of reactions of the frustrated Lewis pairs (FLPs) with carbon dioxide (CO2) and hydrogen (H2) are studied by using quantum chemical modelling. FLPs are relatively novel chemical systems in which steric effects prevent a Lewis base (LB) from donating its electron pair to a Lewis acid (LA). LÄS MER
