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 .
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.
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.
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 ...
The leaf window is also known as a fenestra, [5] and is a translucent structure that transmits light, as in Fenestraria. Examples of fenestrate structures in the fungal kingdom include the symmetrically arranged gaps in the indusium ("skirt") of the mushroom Phallus duplicatus , [ 6 ] and the thallus of the coral lichen Pulchrocladia retipora .
Warping was the former practice of letting turbid river water flood onto agricultural land, so that its suspended sediment could form a layer, before letting the water drain away. In this way poor soils were covered with fertile fine silt (or warp), and their rentable value was increased.
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 ...
Critical windows in emergency medicine Illustration of a short gamma-ray burst, a transient astronomical event caused by a collapsing star. [1] A window of opportunity, also called a margin of opportunity or critical window, is a period of time during which some action can be taken that will achieve a desired outcome. Once this period is over ...
