Exempel på hur man kan använda COUNTERCURRENT i en mening

• Specifically when set up in a loop with a buffering liquid between the incoming and outgoing fluid running in a circuit, and with active transport pumps on the outgoing fluid's tubes, the system is called a countercurrent multiplier, enabling a multiplied effect of many small pumps to gradually build up a large concentration in the buffer liquid.
• The rete mirabile utilizes countercurrent blood flow within the net (blood flowing in opposite directions) to act as a countercurrent exchanger.
• By means of a countercurrent multiplier system, which uses electrolyte pumps, the loop of Henle creates an area of high urea concentration deep in the medulla, near the papillary duct in the collecting duct system.
• Furthermore, countercurrent gas exchange at the secondary gill lamellae further maximizes oxygen uptake and carbon dioxide release.
• Multi-stage flash distillation (MSF) is a water desalination process that distills sea water by flashing a portion of the water into steam in multiple stages of what are essentially countercurrent heat exchangers.
• Lyman Craig's development of countercurrent distribution began with studying the distribution of a pharmaceutical, mepacrine (atabrine), between the two layers of an ethylene dichloride, methanol, and aqueous buffer biphasic solvent system.
• The discontinuous mode of operation allows exploiting the advantage of solvent gradients, but it implies high solvent consumptions and low productivities with respect to continuous countercurrent processes.
• The body has compensatory mechanisms, like the cremaster muscle relaxing and letting the testicle hang further away from the warm body, sweating and a countercurrent exchange of blood cooling inflowing blood.
• Various stages of Parribacus phyllosoma larvae have been found to be carried by the Kuroshio Current and countercurrent between Japanese and Taiwanese waters.
• Historically, it was thought that no commercial countercurrent chromatograph could cope with the high viscosities of ionic liquids.
• The flow of the thin liquid film in the falling film evaporator is possible in two ways: cocurrent and countercurrent.
• Avian respiration follows a system of countercurrent flow in which inspiratory and expiratory processes are dependent on an efficient rate of diffusion to oxygenate blood through the air capillaries.
• An evaporative light scattering detector (ELSD) is a destructive chromatography detector, used in conjunction with high-performance liquid chromatography (HPLC), ultra high-performance liquid chromatography (UHPLC), purification liquid chromatography such as flash or preparative chromatography (using a splitter), countercurrent or centrifugal partition chromatography and supercritical fluid chromatography (SFC).
• Ba'athism emerged as a secular countercurrent to the pan-Islamist ambitions of political Islam and the Muslim Brotherhood in the 1960s.
• The cycle of the dome can be explained as four wind forcing stages: coastal shoaling of the thermocline off the Gulf of Papagayo in February–April, separation from the coast during May–June, countercurrent thermocline ridging during July–November and deepening during December–January.
• The nephrons of avian species can not produce urine that is hyperosmotic to the blood, but the loop of Henle utilises countercurrent multiplication which allows it to become hyperosmotic in the collecting duct.
