The diodicity is then the ratio of the reversed flow resistance to the forward flow resistance: =. If D i > 1 {\displaystyle \mathrm {Di} >1} , the conduit in question has diodic behavior. Thus diodicity is also the ratio of pressure drops for identical flow rates: [ 3 ]
The Sterling submachine gun is a British submachine gun (SMG). It was tested by the British Army in 1944–1945, but did not start to replace the Sten until 1953. A successful and reliable design, it remained standard issue in the British Army until 1994, [18] when it began to be replaced by the L85A1, a bullpup assault rifle.

The SA80 (Small Arms for the 1980s) is a British family of 5.56×45mm NATO service weapons used by the British Army. [4] The L85 Rifle variant has been the standard issue service rifle of the British Armed Forces since 1987, replacing the L1A1 Self-Loading Rifle.
The introduction of the 5.56mm select-fire SA80 series (L85 rifle or individual weapon and L86 light support weapon) to replace 7.62mm weapons and the L2A3 submachine gun and of the LAW 80 to replace the L14A1 gun and the L1A3 66mm rockets from the mid-to-late 1980s onwards led to the rifle group/gun group organisation being abandoned in favour ...
Forward osmosis (FO) is an osmotic process that, like reverse osmosis (RO), uses a semi-permeable membrane to effect separation of water from dissolved solutes.
Flow forming is an incremental metal-forming technique in which a disk or tube of metal is formed over a mandrel by one or more rollers using tremendous pressure. The roller deforms the workpiece, forcing it against the mandrel, both axially lengthening and radially thinning it. [ 1 ]
A typical example of this flow is the forward stagnation point appearing in a flow past a sphere. Paul A. Libby (1974) [ 16 ] (1976) [ 17 ] extended Homann's work by allowing the solid wall to translate along its own plane with a constant speed and allowing constant suction or injection at the solid surface.
