WebApr 11, 2024 · Recent studies have linked spreading depolarization (SD, an electro-chemical wave in the brain following stroke, migraine, traumatic brain injury, and more) with increase in cerebrospinal fluid (CSF) flow through the perivascular spaces (PVSs, annular channels lining the brain vasculature). We develop a novel computational model that … WebMass flow is the movement of dissolved nutrients into a plant as the plant absorbs water for transpiration. The process is responsible for most transport of nitrate, sulfate, calcium … Other types of diffusion [ edit] Anisotropic diffusion, also known as the Perona–Malik equation, enhances high gradients Atomic diffusion, in solids Bohm diffusion, spread of plasma across magnetic fields Eddy diffusion, in coarse-grained description of turbulent flow Effusion of a gas through small ... See more Diffusion is the net movement of anything (for example, atoms, ions, molecules, energy) generally from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in See more "Bulk flow" is the movement/flow of an entire body due to a pressure gradient (for example, water coming out of a tap). "Diffusion" is the gradual movement/dispersion of concentration within a body, due to a concentration gradient, with no … See more Diffusion flux Each model of diffusion expresses the diffusion flux with the use of concentrations, densities and their derivatives. Flux is … See more Diffusion coefficient in kinetic theory of gases The diffusion coefficient $${\displaystyle D}$$ is … See more The concept of diffusion is widely used in: physics (particle diffusion), chemistry, biology, sociology, economics, and finance (diffusion of people, … See more In the scope of time, diffusion in solids was used long before the theory of diffusion was created. For example, Pliny the Elder had previously described the cementation process, which produces steel from the element iron (Fe) through carbon diffusion. Another example is … See more One common misconception is that individual atoms, ions or molecules move randomly, which they do not.
