  1. 6. 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

  2. 7. Wear mechanisms in sheet metal forming Effects of tool microstructure, adhesion and temperature

    University dissertation from Karlstad : Karlstad University

    Author : Anders Gåård; Karlstads universitet.; Karlstads universitet.; Karlstads universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Materials Engineering; Galling; sheet metal forming; wear; friction; adhesion; temperature;

    Abstract : The general trend in the car body manufacturing industry is towards low-series production and reduction of press lubricants and car weight. The limited use of lubricants, in combination with the introduction of high and ultrahigh-strength sheet materials, continuously increases the demands on the forming tools. READ MORE

  3. 8. On Adhesion and Galling in Metal Forming

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Magnus Hanson; Uppsala universitet.; [2008]
    Keywords : Engineering physics; adhesion; galling; dry sliding; stainless steel; vanadium nitride; metal forming; Teknisk fysik;

    Abstract : Metal forming is widely used in the industry to produce cans, tubes, car chassis, rods, wires etc. Forming certain materials such as stainless steel, aluminium and titanium, is often difficult, and problems associated with transfer of work material to the tool material are frequent.

  4. 9. Adhesion Dependent Signals Cell Survival, Receptor Crosstalk and Mechanostimulation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anjum Riaz; Uppsala universitet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Integrins; Signal transduction; Protein kinase B; Akt; PI3K; Heparanase; ROS; Mechanosignalling; Molekylär cellbiologi; Molecular Cellbiology; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi; Cellforskning; Cell Research;

    Abstract : The integrin family of cell surface receptors is evolutionary conserved and found in all multicellular animals. In humans 8-alpha and 18-beta integrins are non-covalently associated into 24 dimers. Integrins mediate cell-extracellular matrix and cell-cell interactions and participate in cell signalling.

  5. 10. Outcome and prevention strategies in peritoneal adhesion formation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Fanny Fredriksson; Uppsala universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peritoneal adhesion prevention; inflammatory cytokines; experimental adhesion model; adhesive small bowel obstruction; adhesion-related morbidity; Barnkirurgi; Pediatric Surgery;

    Abstract : Peritoneal adhesions occur in up to 93% of adults after peritoneal trauma during surgery. Most adhesions are asymptomatic but can cause female infertility, small bowel obstruction (SBO) and chronic abdominal pain. Adhesion prophylaxis is needed to reduce the significant morbidity and increased health care costs resulting from peritoneal adhesions. READ MORE
