91Renal function — Diagram showing the basic physiologic mechanisms of the kidney Renal function, in nephrology, is an indication of the state of the kidney and its role in renal physiology. Glomerular filtration rate (GFR) describes the flow rate of filtered fluid …
92Archimedes' principle — Physics. the law that a body immersed in a fluid is buoyed up by a force (buoyant force) equal to the weight of the fluid displaced by the body. * * * Law of buoyancy, discovered by Archimedes, which states that any object that is completely or… …
93Ocean thermal energy conversion — Temperature differences between the surface and 1000m depth in the oceans Ocean Thermal Energy Conversion (OTEC) uses the difference between cooler deep and warmer shallow or surface ocean waters to run a heat engine and produce useful work,… …
94Axial piston pump — An axial piston pump is a positive displacement pump that has a number of pistons in a circular array within a cylinder block. It can be used as a stand alone pump, a hydraulic motor or an automotive air conditioning compressor. Contents 1… …
95Hydraulic accumulator — A hydraulic accumulator is an energy storage device. It is a pressure storage reservoir in which a non compressible hydraulic fluid is held under pressure by an external source. That external source can be a spring, a raised weight, or a… …
96Pelton wheel — The Pelton wheel is among the most efficient types of water turbines. It was invented by Lester Allan Pelton (1829 1908) in the 1870s, and is an impulse machine, meaning that it uses the principle of Newton s second law to extract energy from a… …
97Renal physiology — This illustration demonstrates the normal kidney physiology. It also includes illustrations showing where some types of diuretics act, and what they do. Renal physiology (Latin rēnēs, kidney ) is the study of the physiology of the kidney. This… …
98Underbalanced drilling — Underbalanced drilling, or UBD, is a procedure used to drill oil and gas wells where the pressure in the wellbore is kept lower than the fluid pressure in the formation being drilled. As the well is being drilled, formation fluid flows into the… …
99Intravenous therapy — or IV therapy is the giving of liquid substances directly into a vein. It can be intermittent or continuous; continuous administration is called an intravenous drip. The word intravenous simply means within a vein , but is most commonly used to… …
