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. Skin hydration - How water and osmolytes influence biophysical properties of stratum corneum

   Author : Sebastian Björklund; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stratum corneum; diffusive transport; permeability; flow-through cell; Franz cell; transdermal drug delivery; water activity; vapor pressure; osmotic gradient; relative humidity; ceramide; free fatty acid; cholesterol; keratin filaments; natural moisturizing factor NMF ; urea; glycerol; molecular mobility; 13C natural-abundance solid-state NMR; polarization transfer; isothermal calorimetry; impedance spectroscopy; X-ray diffraction;

   Abstract : The outermost layer of skin (i.e., the stratum corneum, SC) is the interface that separates the water-rich inside of the body from the relatively dry external environment. SC forms an effective permeability barrier, which has to be overcome in transdermal drug delivery. READ MORE

5. 3. The skin surface microenvironment. Aspects on biophysical conditions and microbiology

   Author : Bo Runeman; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Candida albicans; diaper dermatitis; occlusion; skin humidity; skin microflora; skin surface pH; skin temperature; UVB; vapour permeability; vulva;

   Abstract : The influence of skin environmental factors has been investigated in five studies. In the first study, the microbial growth and rash development in diaper dermatitis were studied in order to evaluate a UVB radiation therapy in comparison with a combined antifungal-hydrocortisone cream.

6. 4. Aspects of neonatal intensive care and anesthesia : Thermal balance and respiratory management

   Author : Victoria Karlsson; Johan Ågren; Lena Hellström-Westas; Filip Fredén; Valeria Perez de Sa; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neonatal; anesthesia; kangaroo-mother-care; skin-to-skin care; carbon dioxide;

   Abstract : This thesis is based on four articles originating from three studies conducted in the neonatal intensive care unit and the children’s operating deparment at Uppsala University Hospital, Sweden.The overall aim was to obtain new knowledge about thermal balance and care environment in extremely preterm infants during skin-to-skin care (SSC), evaluate different methods of intraoperative monitoring of carbon dioxide (CO2), and to investigate how different levels of inhaled oxygen affect infants’ oxygenation during anesthesia and surgery.

7. 5. Large organic aerosols in a human exposure chamber : applications in occupational dermatology and lung medicine

   Author : Lennart Lundgren; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Aerosol; bakery dust; bronchoalveolar lavage; chamber design; dermal exposure; exposure chamber; inhalation; large organic aerosols; mannequin; neutralizer; particle size; pinewood dust; skin;

   Abstract : Exposure to large organic aerosol particles may cause respiratory and skin reactions. The use of human exposure chambers offers possibilities for experimental exposure challenges carried out with patients, in research and for investigations of the effects of exposure on the skin and in the respiratory tract.
