  2. Window (geology) - Wikipedia

    en.wikipedia.org/wiki/Window_(geology)

    A tectonic window, or fenster (lit. "window" in German), is a geologic structure formed by erosion or normal faulting on a thrust system. In such a system the rock mass ( hanging wall block ) that has been transported by movement along the thrust is called a nappe .

  3. Wood warping - Wikipedia

    en.wikipedia.org/wiki/Wood_warping

    Wood warping is a deviation from flatness in timber as a result of internal residual stress caused by uneven shrinkage. Warping primarily occurs due to uneven expansion or contraction caused by changes in moisture content.

  4. Near-infrared window in biological tissue - Wikipedia

    en.wikipedia.org/wiki/Near-infrared_window_in...

    The near-infrared (NIR) window (also known as optical window or therapeutic window) defines the range of wavelengths from 650 to 1350 nanometre (nm) where light has its maximum depth of penetration in tissue. [1] Within the NIR window, scattering is the most dominant light-tissue interaction, and therefore the propagating light becomes diffused ...

  5. Slab window - Wikipedia

    en.wikipedia.org/wiki/Slab_window

    Diagram of a cross-section of the Patagonia slab window. The Nazca plate and Antarctic plate are colliding with the South American plate at the Chile Ridge. [1]In geology, a slab window is a gap that forms in a subducted oceanic plate when a mid-ocean ridge meets with a subduction zone and plate divergence at the ridge and convergence at the subduction zone continue, causing the ridge to be ...

  6. Optical window - Wikipedia

    en.wikipedia.org/wiki/Optical_window

    The optical window is the portion of the optical spectrum that is not blocked by the Earth's atmosphere. The window runs from around 300 nanometers ( ultraviolet-B ) up into the range the human eye can detect, roughly 400–700 nm and continues up to approximately 2 μm .

  7. List of unsolved problems in biology - Wikipedia

    Unsolved problems relating to the structure and function of non-human organs, processes and biomolecules include: Korarchaeota (archaea). The metabolic processes of this phylum of archaea are so far unclear.

  8. Bird–window collisions - Wikipedia

    en.wikipedia.org/wiki/Bird–window_collisions

    Windows fitted with a dotted grid pattern to prevent bird collisions. There are several methods of preventing bird-window strikes. The use of ultraviolet (UV) signals to make windows appear visible to birds, while once one of the most common means of combatting this issue, is no longer recommended by experts. This is because while some birds ...

  9. Biological rules - Wikipedia

    en.wikipedia.org/wiki/Biological_rules

    The pygmy mammoth is an example of insular dwarfism, a case of Foster's rule, its unusually small body size an adaptation to the limited resources of its island home.. A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms.
