  1. 1. Interfacial Adhesion Failure Impact on print-coating surface defects

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Hajer Kamal Alm; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ink-paper coating adhesion; offset printing; calcium carbonate pigments; polyacrylate; dispersant; print mottle; surface chemistry; hygroscopy of surfaces; coating structure; print quality; water interference mottle; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The aim of this work was to develop a solid knowledge on formulation effects controlling offset ink-paper coating adhesion and to identify key factors of the coating and printing process affecting it. Focus lay on comprehending the impact of pigment dispersant on ink-paper coating adhesion and ultimately on the print quality of offset prints. READ MORE

  2. 2. 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. 3. Adhesion in the wheel-rail contact under contaminated conditions

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Yi Zhu; KTH.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesion; wheel-rail contact; contaminants; rough surfaces;

    Abstract : Railway vehicles require a certain level of adhesion between wheel and rail to operate efficiently, reliably, and economically. Different levels of adhesion are needed depending on the vehicle running conditions. READ MORE

  4. 4. Thrombospondin 1, an autocrine regulator in T cell adhesion and migration

    University dissertation from Umeå : Klinisk mikrobiologi

    Author : ShuShun Li; Umeå universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; T cell; adhesion; migration; thrombospondin; Immunologi; MEDICINE Microbiology; immunology; infectious diseases Immunology; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar Immunologi; immunologi; Immunology;

    Abstract : Lymphocytes, the principal cells of the immune system, perform the immune function throughout the body by their unique capacity to circulate in blood stream and lymphatic vessels and migrate in lymphoid and non-lymphoid tissues. The mechanisms regulating lymphocyte adhesion and migration, interactions with cells and components within the extracellular matrix are not fully understood. READ MORE

  5. 5. Interactions between whole blood and TiO₂ surfaces with focus on adhesion and activation of PMN granulocytes

    University dissertation from Göteborg

    Author : Cecilia Eriksson; Göteborgs universitet.; Gothenburg University.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; titanium; TiO2; surface roughness; oxide thickness; wettability; whole blood; inflammation; wound healing; platelets; PMN granulocytes; adhesion; activation; receptor expression; respiratory burst.;

    Abstract : Foreign materials come in contact with the human body more and more frequently. The surgical procedure of inserting an implant into the body will cause bleeding, evoke an inflammatory response and initiate a healing process, ultimately leading to acceptance or rejection of the material.
