Most programs are more complex than this, so other .cxx files can be written that call the FLUID functions. These .cxx files must include the .h file, or they can include the .cxx file so it still appears to be a single source file. Normally the FLUID file defines one or more functions or classes, which output C code. Each function defines a one or more FLTK windows, and all the widgets that go inside those windows.

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 . They were the first non Seattle band to sign to the record label . 2008 reunion The Fluid reunited to perform at Sub Pop Records 20th Anniversary at Redmond, Washington Redmond s Marymoor Park in Seattle in July 2008.

Transcellular fluid is the portion of total body water contained within epithelial lined spaces. It is the smallest component of extracellular fluid , which also includes interstitial fluid and Blood plasma plasma . It is often not calculated as a fraction of the extracellular fluid, but it is about 2.5 of the total body water. Examples of this fluid are cerebrospinalfluid , and aqueous humor ocular fluid , synovial fluid joint fluid , and urinary bladder bladder urine . ref http www.anaesthesiamcq.com FluidBook fl2 1.php Fluid Physiology 2.1 Fluid Compartments Bot generated title ref Composition Due to the varying locations of transcellular fluid, the composition changes dramatically.

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 .

In some animals, including mammal s, the extracellular fluid can be divided into two major subcompartments, interstitial fluid and blood plasma . The extracellular fluid also includes the transcellular fluid making up only about 2.5 percent of the ECF. In humans, the normal glucose concentration of extracellular fluid that is regulated by homeostasis is approximately 5 molarity mM .

In physiology , the term serous fluid is used for various bodily fluid s that are typically pale yellow and transparent, and of a benign nature, that fill the inside of body cavity body cavities . Serous fluid originates from serous gland s, with secretions enriched with protein s and water. Serous fluid may also originate from mixed glands, which contain both mucous and serous cells. A common trait of serous fluids is their role in assisting digestion , excretion , and Respiratory system respiration . In medical fields, especially cytopathology , serous fluid is a synonym for effusion fluid s from various body cavities . There are many causes of effusions which include involvement of the cavity by cancer . Cytopathology evaluation is recommended to evaluate the causes of effusions in these cavities. ref name Shidham Examples Saliva consists of mucus and serous fluid the serous fluid contains the enzyme amylase important for the digestion of carbohydrate s. Minor Von Ebner s glands salivary glands of von Ebner present on the tongue secretion secrete the amylase. The parotid gland produces purely serous saliva. The other major salivary gland s produce mixed serous and mucus saliva. Another type of serous fluid is secreted by the serous membrane s or serosa , two layered membranes which line the body cavities . The serous fluid between the two layers acts as a lubricant and reduces friction from muscle movement. This can be seen in the lungs .
