81Thermal conductivity — In physics, thermal conductivity, k, is the property of a material that indicates its ability to conduct heat. It appears primarily in Fourier s Law for heat conduction.First, we define heat conduction by the formula::: H=frac{Delta Q}{Delta t}=k …
82Hydraulic conductivity — Hydraulic conductivity, symbolically represented as K, is a property of vascular plants, soil or rock, that describes the ease with which water can move through pore spaces or fractures. It depends on the intrinsic permeability of the material… …
83BORGESIUS — NETHERLANDS (see also List of Individuals) 27.5.1864 Norg/NL 27.5.1941 Den Haag/NL Anne Herman Borgesius studied natural sciences at Groningen University and from 1901 to 1922 joined as a staff member Den Haag University. He was a Member of… …
84Hydrology — Water covers 70% of the Earth s surface. Hydrology is the study of the movement, distribution, and quality of water on Earth and other planets, including the hydrologic cycle, water resources and environmental watershed sustainability. A… …
85Outline of hydrology — The following outline is provided as an overview of and topical guide to hydrology: Hydrology – study of the movement, distribution, and quality of water on Earth and other planets, including the hydrologic cycle, water resources and… …
86Liquid crystal — Schlieren texture of liquid crystal nematic phase Liquid crystals (LCs) are a state of matter that have properties between those of a conventional liquid and those of a solid crystal.[1] For instance, an LC may flow like a liquid, but its… …
87Ricci curvature — In differential geometry, the Ricci curvature tensor, named after Gregorio Ricci Curbastro, provides one way of measuring the degree to which the geometry determined by a given Riemannian metric might differ from that of ordinary Euclidean n… …
88History of physics — The modern discipline of physics emerged in the 17th century following in traditions of inquiry established by Galileo Galilei, René Descartes, Isaac Newton, and other natural philosophers.Fact|date=September 2008 Prior to this time, a unified… …
89Thermal history modelling — is an exercise undertaken during basin modelling to evaluate the temperature history of stratigraphic layers in a sedimentary basin.The thermal history of a basin is usually calibrated using thermal indicator data, including vitrinite reflectance …
90Evaporator — Within a downstream processing system, several stages are used to further isolate and purify the desired product. The overall structure of the process includes pre treatment, solid liquid separation, concentration, and purification and… …
