    and throughput. Upstream Side (of filter): The feed side of the filter. Terms Used When Discussing Hybridization Membranes. Active Blotting: The transfer of macromolecules (DNA, RNA, and protein) to a substrate (a membrane filter) using a voltage gradient (electricity), vacuum, or positive pressure
  • Medical Device Link .
    passed through it, and thus purify the fluid. Most of these are driven by pressure or by a concentration gradient. In a separation application, the structure of the filter and its permeability and particle-retention capacity are critical. All other IVD filter applications can be grouped under
  • Medical Device Link .
    Energy-Efficient Battery Runs on Body Heat A wafer-thin, fingernail-sized thermoelectric generator converts low-gradient body-heat flow into electrical power that can be used to run embedded or attachable medical devices. The ½ x ½-in. ceramic battery does not contain any chemicals
  • Estimation of Curvature from micro-CT Liquid-Liquid Displacement Studies with Pore Scale Resolution
    ) an anisotropic diffusion filter was applied, (2) known. regions (i.e. regions internal to a given phase) were marked with a simple threshold, (3). the image gradient magnitude was calculated, and (4) a watershed algorithm was applied. The watershed algorithm utilizes the gradient magnitude to dilate
  • Wall Shear Stress Measurements in Two-Phase Flow using PIV, an Optical Sensor, and Wall Pressure Transducer (.pdf)
    the boundary layer. The wall shear stress in the channel was measured by means of three independent methods: measurement of the pressure gradient by an accurate differential pressure transducer, Particle Image Velocimetry (PIV), and an optical wall shear stress sensor. The three methods showed

    , of bacterirodopsin. It is a photon-driven proton pump found in some bacteria that converts light to a proton gradient which is used to generate chemical energy in the form of adenosine triphosphate. The trimer part of the protein, a polymer made of three monomers, is highlighted. A probe for measuring electrical
