  2. Trunnion - Wikipedia

    en.wikipedia.org/wiki/Trunnion

    A trunnion (from Old French trognon 'trunk') [1] is a cylindrical protrusion used as a mounting or pivoting point. First associated with cannons, they are an important military development. First associated with cannons, they are an important military development.

  3. Biological network - Wikipedia

    en.wikipedia.org/wiki/Biological_network

    A biological network is a method of representing systems as complex sets of binary interactions or relations between various biological entities. [1] In general, networks or graphs are used to capture relationships between entities or objects. [1]

  4. Bascule bridge - Wikipedia

    en.wikipedia.org/wiki/Bascule_bridge

    The rolling lift trunnion (sometimes a "Scherzer" rolling lift), raises the span by rolling on a track resembling a rocking-chair base. The "Scherzer" rolling lift is a refinement patented in 1893 by American engineer William Donald Scherzer. [3] The rarer Rall type combines rolling lift with longitudinal motion on trunnions when opening. [4]

    en.wikipedia.org/wiki/Systems_biology

    Systems biology is the computational and mathematical analysis and modeling of complex biological systems.It is a biology-based interdisciplinary field of study that focuses on complex interactions within biological systems, using a holistic approach (holism instead of the more traditional reductionism) to biological research.

Animal Locomotion: An Electro-photographic Investigation of Consecutive Phases of Animal Movements is a series of scientific photographs by Eadweard Muybridge made in 1884 and 1885 at the University of Pennsylvania, to study motion in animals (including humans).

  7. Biological system - Wikipedia

    en.wikipedia.org/wiki/Biological_system

    A biological system is a complex network which connects several biologically relevant entities. Biological organization spans several scales and are determined based different structures depending on what the system is. [1] Examples of biological systems at the macro scale are populations of organisms.

  8. Developmental bioelectricity - Wikipedia

    en.wikipedia.org/wiki/Developmental_bioelectricity

    Developmental bioelectricity is a sub-discipline of biology, related to, but distinct from, neurophysiology and bioelectromagnetics. Developmental bioelectricity refers to the endogenous ion fluxes, transmembrane and transepithelial voltage gradients, and electric currents and fields produced and sustained in living cells and tissues.

  9. Biological applications of bifurcation theory - Wikipedia

    en.wikipedia.org/wiki/Biological_applications_of...

    In the context of a biological system, bifurcation theory describes how small changes in an input parameter can cause a bifurcation or qualitative change in the behavior of the system. The ability to make dramatic change in system output is often essential to organism function, and bifurcations are therefore ubiquitous in biological networks ...
