  • Effects of Sample Disturbance on Soil Water Potential Measurements (.pdf)
    effects and relate them to the range of water potential of the soil sample. A soil is often modeled as a bundle of capillary tubes with a wide range of pore sizes.
  • The Best of Pittcon 2007
    with company founder Jim Waters, Meanwhile, fellow Silver winner Paraytec s ActiPix capillary-based UV absorbance detectors and spectrophotometers use a patented technology to extend the use of UV Vis. The ActiPix D100 combines the self focusing capabilities of fused silica capillaries with
  • Moisture Sorption Isotherm Method (.pdf)
    The relationship between water activity (aw) and moisture content at a given temperature is called the moisture sorption isotherm. This relationship is complex and unique for each product due to different interactions (colligative, capillary, and surface effects) between the water and the solid
  • Ensuring Better Control of Granulation
    of the liquid/air interface and the hydrostatic suction pressure in the liquid bridge. When all the air has been displaced from between the particles, the capillary state is reached, and the particles are held by capillary suction at the liquid/air interface. The funicular state represents
  • MICRO:Tech Emergent
    the damage associated with surface tension and capillary forces. At the same time, scCO 's gaslike properties facilitate its removal, obviating residue concerns. The effect of using a standard aqueous-based chemistry versus an scCO formulation to remove residues from fragile structures is highlighted
  • MICRO:Extreme Silicon by Peng Sun, p.41 (April '99)
    effects on device fabrication. Unfortunately, methods for measuring nonmetallic ions at the ultratrace levels found on wafer surfaces lag behind the industry's demands. Recent research in this area has focused on using ion chromatography (IC) and capillary electrophoresis (CE). Figure 1: Schematic
  • Felt Seals
    . Wool felt seals, in a dry state, are highly effective as filters in removing particles of 0.7- m size and larger. When saturated in lubricants, even smaller particles are trapped and retained. Capillary properties of a felt seal ensure lubrication after long idle periods. Storage capacity is largely
  • "Hare's Looking at You, Kid. "
    which piece it attaches to, a microfabrication technique known as self-assembly. Capillary forces the same forces that drive water upward in plants pull the pieces together. The prototype lens does not correct the wearer 's vision, but the technique could be used on corrective lenses, Parviz says

  • Capillary Electrophoresis
    AccuSep polyimide fused-silica capillaries ( Waters , Milford, MA) of dimension 60 cm × 50 m ID were used.
  • Stone in Architecture
    by capillary water absorption.
  • Progress in Polymers in Concrete
    In our present research, the results exhibit that as the polymer/cement ratio (mp/mc) increases from 0% to 5%, the reduction in the capillary water absorption and the penetration depth of water into mortar is significant.
  • Introduction to Phytoremediation of Contaminated Groundwater
    As stated earlier, the magnitude of the ETp at a site provides an estimate of the atmospheric demand for water, which can be supplied by surface water, soil moisture, cap- illary water , and groundwater.
  • Unsaturated Soil Mechanics in Engineering Practice Complete Document
    Let us consider the vertical force equilibrium of the cap- illary water in the tube shown in Fig. 2.40.
  • Stone in Architecture
    In contrast, the maximum pores in S0 are smaller than 0.1 μm, which cannot be filled by capillary water absorption.
  • Encyclopedia of Agrophysics
    Bypass flow has previously been defined as the flow of “free” (i.e., non- or over- capillary ) water along macropores into and through an unsaturated soil matrix (Bouma, 1981; van Stiphout et al., 1987); in the field bypass flow often starts when …

    These range from ground water flow, to water intercepted by vegetation, water intercepted by surface depres- sions, capillary water rise in the soil, and water stored in the tis- sue of plants to name a few.
