Image Grosser Aletschgletscher 3178.JPG thumb Glacier IsostaticDepression is the term used by geologists for the sinking of large parts of the Earth s crust into the asthenosphere . The sinking is caused by a heavy weight placed on the Earth s surface. Often this is caused by the heavy weight of glacial ice due to continental glaciation , a process in which permanent ice places pressure on the Earth s crust thereby depressing it with its weight. After continental glaciation has receded, it is common for isostatic rebound to take place.

Unreferenced date July 2008 Hot isostatic pressing HIP is a manufacturing process used to reduce the gas porosity casting porosity of metal s and influence the density of many ceramic materials. This improves the material s mechanical properties and workability. The HIP process subjects a component to both elevated temperature and isostatic gas pressure in a high pressure containment vessel. The pressurizing gas most widely used is argon . An inert gas is used, so that the material does not chemically react. The chamber is heated, causing the pressure inside the vessel to increase. Many systems use associated gas pumping to achieve the necessary pressure level. Pressure is applied to the material from all directions hence the term isostatic . For processing Casting metalworking casting s, the inert gas is applied between convert 7350 psi MPa abbr on and convert 45000 psi MPa abbr on , with convert 15000 psi MPa abbr on being most common. Process soak temperatures range from convert 900 F abbr on for aluminum castings to convert 2400 F abbr on for nickel based superalloy s. When castings are treated with HIP, the simultaneous application of heat and pressure eliminates internal voids and microporosity through a combination of plastic deformation , creep , and diffusion bonding this process improves fatigue resistance of component. Primary applications are the reduction of microshrinkage , the consolidation of powder metals, ceramic composites and metal Cladding metalworking cladding . Hot isostatic pressing is also used as part of a sintering powder metallurgy process and for fabrication of metal matrix composite s.

Unreferenced date November 2010 A concept in selective breeding and zoology , outbreeding depression refers to cases when offspring from cross fertilization crosses between individuals from different populations have lower fitness than progeny from crosses between individuals from the same population. In selective breeding, the concept is opposed to inbreeding depression . This phenomenon can occur in two ways. First, selection in one population might produce a large body size, whereas in another population small body size might be more advantageous. Gene flow between these populations may lead to individuals with intermediate body sizes, which may not be adaptive in either population. It might be that, in a certain environment, having either a large or a small bodies is advantageous, whereas an intermediate sized body is comparatively disadvantageous.
