Description: in either a net efflux or influx pathway, depending on the chemical concentration gradients of potassium and chloride. The encoded protein can act as a homomultimer, or as a heteromultimer with other K-Cl cotransporters, to maintain chloride homeostasis in neurons.
Supplier: Shimadzu Scientific Instruments, Inc.
Description: flow cell. System reliability has been further improved by standardizing the flow line arrangement in order to integrate the units. As with its predecessor, the LC-2010, the LC-2010HT has unparalleled flow rate and gradient concentration accuracy, but now boasts near-zero sample carryover with its
- Pump Operating Method: Gradient
- Instrument Type: Fixtured or Permanent
- Analysis Method: Analytical Analysis
- Detection Method: Ultraviolet / Visible Light Detector
Supplier: GENEQ, inc.
Description: steady, direct diffusion of oxygen into an aquifer through pressurized silicone or LDPE tubing. Continuous, consistent release of oxygen into the tubing creates the ideal concentration gradient driving this passive system, without ‘bubbling off’ excess oxygen. Emitters are ideal
Supplier: Omegadyne, Inc.
Description: The linear pattern strain gages are available in a variety of styles and sizes. OMEGADYNE® offers miniature linear patterns for strain measurement of a stress concentration or high gradient areas. The terminations are offered both at one end of the grid, or with one at each end of the grid
- Construction: Electrical Resistance
- Arrangement (If Applicable): Uniaxial
- Specialty Applications: Transducer Gauge
- Nominal Resistance: 1000
Supplier: American Water Works Association
Description: , the velocity gradient, particle concentration, and chemical conditions were varied independently. Detailed measurements of the particle size distribution were made, and the extent of change caused by each variable was quantified. The effects of time, concentration, and chemical conditions were reasonably well
Supplier: LI-COR Biosciences
Description: factors (soil temperature, soil moisture, etc.) and biological factors (above ground canopy size and growth, etc.). Soil CO2 efflux is a physical process driven primarily by the CO2 concentration diffusion gradient between the upper soil layers and the atmosphere near the soil surface. The measurement

In the vicinity of the surface, there are extreme solute concentration gradients involving colloids, ions and organics, which, though difficult to access, are the focus for important interfacial events. The conventional consideration

into it. This property is expressed as the moisture-vapor-transmission rate (MVTR). The greater concentration gradient provides a stronger driving force for the MVT, thus creating a wicking action in the material.
