      • The flash point is a general indication of the flammability or combustibility of a liquid. Below the flash point, insufficient vapour is available to support combustion. At some temperature above the flash point, the liquid will produce enough vapour to support combustion. (This temperature is known as the fire point.)

  3. Jun 1, 2022 · River flashiness is a measure of how quickly and how high streamflow rises and falls in response to watershed input. Broadly, flashiness is therefore an integrator of event dynamics (e.g., precipitation intensity, duration, and antecedent conditions) and watershed characteristics (e.g., slope, soil properties, and land use/land cover).

  5. What is Falsifiability? Falsifiability is the assertion that for any hypothesis to have credence, it must be inherently disprovable before it can become accepted as a scientific hypothesis or theory.

  6. 3 days ago · Cryo-electron tomography (cryo-ET), most commonly applied to whole cells, provides 3D visualization of organelles and protein complexes at nanometer resolution in their physiological environments. This is done by opening windows into the cell with focused ion beam (FIB) milling of a vitrified cell. A series of 2D images are taken of this ...

  7. Jun 8, 2007 · Flashiness is an important component of a stream's hydrologic regime. A variety of land use and land management changes may lead to increased or decreased flashiness, often to the detriment of aquatic life. This paper presents a newly developed flashiness index, which is based on mean daily flows.

  8. Apr 1, 2004 · The term flashiness reflects the frequency and rapidity of short term changes in streamflow, especially during runoff events. Flashiness is an important component of...
