Extracellularfluid ECF or extracellularfluid volume ECFV usually denotes all body fluid outside of cells. The remainder is called intracellular fluid . In some animals, including mammal s, the extracellularfluid can be divided into two major subcompartments, interstitial fluid and blood plasma . The extracellularfluid also includes the transcellular fluid making up only about 2.5 percent of the ECF. In humans, the normal glucose concentration of extracellularfluid that is regulated by homeostasis is approximately 5 molarity mM . The pH of extracellularfluid is tightly regulated by Buffer solution buffers around 7.4.

After early 1980s Denver punk band Frantix broke, up bassist Matt Bischoff, drummer Garrett Shavlik and guitarist James Clower began playing as Madhouse. On July 5, with new band members Rick Kulwicki guitar and John Robinson vocals , they played their first gig at the German House Denver Turnverein as The Fluid , which was the only name all five members could agree upon. In 1986 the Fluid released their first album, Punch N Judy on Rayon Records. The album was also licensed to and released by the German label Glitterhouse . They toured for the next two years in support of the album. In 1988, they released the album Clear Black Paper on Sub Pop .

Unreferenced stub auto yes date December 2009 The extracellular field potential is the electrical potential produced by Cell biology cell s, e.g. Neuron nerve or Muscle fiber muscle cell s, outside of the cell. Electrophysiology Electrophysiological studies investigate these potentials using extracellular microelectrode s. In these experiments the extracellular field potential will be detected as an electrical potential whose source and composition is often ambiguous, making its interpretation difficult. Individual nerve cells neuron s may produce Voltage spike spike s seen as peaks of some tens to hundreds of microvolts. Contributions from neighbouring neurons may overlap, producing extracellular potentials of up to several millivolts. Spatially integrating over even larger populations of cells, i.e. lumps of nervous tissue nervous or muscle muscular tissue , will produce signals commonly called local field potential s LFP that can be recorded either in the tissue or with suitable equipment at the body surface as, e.g., electroencephalogram EEG , electrocardiogram ECG , or electromyogram EMG . For individual cells, the time course of the extracellular potential theoretically is inversely proportional to the transmembrane current. In practice, however, this is complicated considerably by the very complex Morphology biology morphology of neurons and the overlap of contributions from adjacent cells.

Unreferenced date December 2009 In atmospheric dynamics and fluid dynamics , a hydrostatic fluid is a fluid in which fluid stresses act isotropic ally and fluid elements are in local equilibrium with one another. Thus, all directional fluid stresses, normally represented as vectors, can be summarized by a scalar physics scalar quantity called the hydrostatic pressure , which can still depend on position. The stress mechanics stress tensor takes on the form math sigma ij p delta ij math , where math p math is the hydrostatic pressure, and math delta ij math is the kronecker delta The equilibrium which exists in a hydrostatic fluid is often the result of a balance between forces that compress the fluid and forces that resist compression. For example, on earth, the atmosphere is compressed against the surface by gravity and supported by its internal energy . This is often referred to as hydrostatic equilibrium .

norefs date March 2010 A jet is an efflux of fluid that is projected into a surrounding medium, usually from some kind of a nozzle , aperture or orifice. Jets can travel long distances without dissipating. In the Earth s atmosphere there exist jet stream s that travel thousands of miles. Jet fluid has higher momentum compared to the surrounding fluid medium.In the case where the surrounding medium is assumed to be made up of the same fluid as the jet and this fluid has a viscosity then the surrounding fluid near the jet is assumed to be carried along with the jet by a process called entrainment . Some animals, notably cephalopods use a jet to propel themselves in water. Similarly, a jet engine as it name suggests, emits a jet used to propel rocket s, aircraft , jetboat s, and submarine s.
