In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell. Looking at the process starting from the interior of the cell: The pump has a higher affinity for Na + ions than K + ions, thus after binding ATP , binds 3 intracellular Na + ions.
The parallel-plate flow chamber, in its original design, is capable of producing well-defined wall shear-stress in the physiological range of 0.01-30 dyn/cm 2.Shear stress is generated by flowing fluid (e.g., anticoagulated whole blood or isolated cell suspensions) through the chamber over the immobilized substrate under controlled kinematic conditions using a syringe pump.

A flow in manifold can be represented by a channel network model. A multi-scale parallel channel networks is usually described as the lattice network using analogy with the conventional electric circuit methods. [4] [5] [6] A generalized model of the flow distribution in channel networks of planar fuel cells. [6]
The pump used a leather hose which did not need to self-open when released by the rollers, instead relying on the incoming water having sufficient pressure to fill the open inlet end on each cycle. [1] The peristaltic pump was first patented in the United States by Rufus Porter and J. D. Bradley in 1855 (U.S. Patent number 12753) [2] as a well ...
Compared to the eukaryotic cell cycle, the prokaryotic cell cycle (known as binary fission) is relatively simple and quick: the chromosome replicates from the origin of replication, a new membrane is assembled, and the cell wall forms a septum which divides the cell into two. [7]
Warman centrifugal pump in a coal preparation plant application A pair of centrifugal pumps for circulating hot water within a hydronic heating system. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine ...
Thermostatically controlled circulation pumps cycle on and off to maintain a user's chosen temperature and consume less energy than a continuously operating pump. By installing a thermostatically controlled pump just after the farthest fixture on the loop, cyclic pumping maintains ready hot water up to the last fixture on the loop instead of ...
