11Pressure-gradient force — The pressure gradient force is not actually a force but the acceleration of air due to pressure difference (a force per unit mass). It is usually responsible for accelerating a parcel of air from a high atmospheric pressure region to a low… …
12Multicolumn countercurrent solvent gradient purification — (MCSGP) is a form of chromatography that is used to separate or purify biomolecules from complex mixtures. It was developed at the Swiss Federal Institute of Technology Zürich by Aumann and Morbidelli.[1] The process consists of three to six… …
13Cold-core low — Image of an upper tropospheric cyclonic vortex in the western North Pacific, a cold core low A cold core low …
14Ruling gradient — The ruling gradient (or ruling grade) of a section of railway line is the steepest section of that line. The ruling gradient is important in assigning locomotives to trains, as the locomotives must have sufficient power to pull the train over the …
15Pressure gradient — In atmospheric sciences (meteorology, climatology and related fields), the pressure gradient (typically of air, more generally of any fluid) is a physical quantity that describes in which direction and at what rate the pressure changes the most… …
16Geothermal gradient — The geothermal gradient is the rate of increase in temperature per unit depth in the Earth. It varies with location and is typically measured by determining the bottom open hole temperature after borehole drilling. To achieve accuracy the… …
17Image gradient — In graphics software for digital image editing, the term gradient is used for a gradual blend of colour which can be considered as an even gradation from low to high values, as used from white to black in the images to the right.Mathematically,… …
18Adverse pressure gradient — An adverse pressure gradient occurs when the static pressure increases in the direction of the flow. This is important for boundary layers, since increasing the fluid pressure is akin to increasing the potential energy of the fluid, leading to a… …
19Salt Gradient Solar Ponds — Consist of three main layers. The top layer is near ambient and has low salt content. The bottom layer is hot, typically 160 F to 212 F (71 C to 100 C), and is very salty. The important gradient zone separates these zones. The gradient zone… …
