  2. Adhesion - Wikipedia

    en.wikipedia.org/wiki/Adhesion

    Note 1: Adhesion requires energy that can come from chemical and/or physical linkages, the latter being reversible when enough energy is applied. Note 2: In biology, adhesion reflects the behavior of cells shortly after contact to the surface. Note 3: In surgery, adhesion is used when two tissues fuse unexpectedly. [1]

  3. Group cohesiveness - Wikipedia

    en.wikipedia.org/wiki/Group_cohesiveness

    Group cohesiveness, also called group cohesion, social harmony or social cohesion, is the degree or strength of bonds linking members of a social group to one another and to the group as a whole. [1] Although cohesion is a multi-faceted process, it can be broken down into four main components: social relations , task relations, perceived unity ...

  4. Contact mechanics - Wikipedia

    en.wikipedia.org/wiki/Contact_mechanics

    Greenwood and Williamson in 1966 (GW) [31] proposed a theory of elastic contact mechanics of rough surfaces which is today the foundation of many theories in tribology (friction, adhesion, thermal and electrical conductance, wear, etc.). They considered the contact between a smooth rigid plane and a nominally flat deformable rough surface ...

  5. Differential adhesion hypothesis - Wikipedia

    en.wikipedia.org/wiki/Differential_adhesion...

    Differential adhesion hypothesis (DAH) is a hypothesis that explains cellular movement during morphogenesis with thermodynamic principles. In DAH tissues are treated as liquids consisting of mobile cells whose varying degrees of surface adhesion cause them to reorganize spontaneously to minimize their interfacial free energy . [ 1 ]

  6. Asabiyyah - Wikipedia

    en.wikipedia.org/wiki/Asabiyyah

    'Asabiyyah (Arabic: عصبيّة, romanized: ʿaṣabiyya, also 'asabiyya, 'group feeling' or 'social cohesion') is a concept of social solidarity with an emphasis on unity, group consciousness, and a sense of shared purpose and social cohesion, originally used in the context of tribalism and clanism.

  7. Cohesion (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Cohesion_(chemistry)

    Adhesion – the attraction of molecules or compounds for other molecules of a different kind; Specific heat capacity – the amount of heat needed to raise the temperature of one gram of a substance by one degree Celsius; Heat of vaporization – the amount of energy needed to change one gram of a liquid substance to a gas at constant temperature

  8. Adhesive bonding - Wikipedia

    en.wikipedia.org/wiki/Adhesive_bonding

    According to IUPAC, adhesion is the "process of attachment of a substance to the surface of another substance". Interactions between the adhesive and substrate have a very short range of less than one nanometre. Therefore, good wetting of the materials to be joined by the adhesive in its liquid state is required to produce a high quality bond ...

  9. Adhesion G protein-coupled receptor - Wikipedia

    en.wikipedia.org/wiki/Adhesion_G_protein-coupled...

    One characteristic of adhesion GPCRs is their extended extracellular region. This region is modular in nature, often possessing a variety of structurally defined protein domains and a membrane proximal GAIN domain. In the aptly named Very Large G protein-coupled Receptor 1 VLGR1 the extracellular region extends up to almost 6000 amino acids.
