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

    Författare :Kenneth Duvefelt; Ulf Olofsson; Emile Van Der Heide; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesion; finger; friction; humidity; material; model; tactile friction; tactility; Machine Design; Maskinkonstruktion;

    Sammanfattning : 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. LÄS MER

  2. 2. Strategies for postoperative adhesion control

    Författare :Kristina Falk; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adhesion formation; adhesion prevention; experimental model; mouse; human; fibrinolysis; bioadhesion; cellulose; hydrophobic modification; t-PA; PAI-1; proCPU; TAFI;

    Sammanfattning : Introduction: Abdominal surgery almost inevitably leads to adhesion formation, which often results in substantial morbidity. The formation of postsurgical adhesions seems to be determined by the balance of fibrin deposition and degradation in an early phase of peritoneal tissue repair. LÄS MER

  3. 3. Outcome and prevention strategies in peritoneal adhesion formation

    Författare :Fanny Fredriksson; Helene Lilja; Bobby Tingstedt; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 4. Adhesion in the wheel-rail contact

    Författare :Yi Zhu; Ulf Olofsson; Anders Söderberg; Zili Li; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesion; wheel-rail contact; contaminants; tribology; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology;

    Sammanfattning : To attract more customers and compete with other modes of transportation, railway transport needs to ensure safety, punctuality, high comfort, and low cost; wheel–rail adhesion, i.e., the transmitted tangential force in the longitudinal direction during driving and braking, plays an important role in all these aspects.

  5. 5. Host ligands and oral bacterial adhesion : studies on phosphorylated polypeptides and gp-340 in saliva and milk

    Författare :Liza Danielsson Niemi; Ingegerd Johansson; Pernilla Lif Holgersson; Jukka Meurman; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adhesion; statherin; gp-340; caseins; human milk; saliva; Streptococcus mutans; Actinomyces; Cariology; Cariologi; kariologi; Cariology;

    Sammanfattning : Infectious diseases e.g. gastric ulcer, caries and perodontitis, are caused by bacteria in a biofilm. Adhesion of bacteria to host ligands e. LÄS MER
