  • hydrophobic
  • These developments have already introduced major improvements to the fields of hydrophobic interaction chromatography, size exclusion chromatography, ion exchange chromatography, and affinity chromatography separations as well as pseudo-solid phase extractions ("pseudo" because of phase transitions). (wikipedia.org)
  • filters
  • Polycap HD (Heavy Duty) capsule filter offers a broad range of particle size retention ratings and excellent filtrate purity with polypropylene filters (PP). (fishersci.com)
  • Coffee filters are made in different shapes and sizes to fit into different holders. (wikipedia.org)
  • Filters with 0.1 µm compared with 0.2 µm pore size have enhanced bacterial removal according to a study. (wikipedia.org)
  • Correctly used, wheel filters with at least pore size 0.5 µm may reduce these impurities entering the blood stream and help avoid vein problems such as collapsed veins, abscesses, infections, embolism, 'dirty tastes', disease and septicemia. (wikipedia.org)
  • particle
  • Polymers such as poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide), polyvinylpyrrolidone, and poly-(diallyldimethylammonium chloride) have been found to act as crystal dispersants, imparting particle-size and morphology control. (wikipedia.org)
  • typically
  • However, as recently seen on The Doctors, a different use of a laser typically used for tattoo removal may offer patients a way to reduce the size of their pores. (americanhealthandbeauty.com)
  • Microdermabrasion devices typically have crystals in them to treat the entire surface of the face for pigment, fine lines and pores," explains Dr. Steinberg, "With the Silk Peel, non-invasive microdermabrasion is combined with medication that is specific to the needs of the patient's skin.

  • Material
  • Evaporation-induced self-assembly usually causes random alignment of the material pores. (wikipedia.org)
  • However, the pores of the material can be blocked during this process so a one-pot synthesis using the necessary components is more advantageous. (wikipedia.org)
  • Unsaturated conditions occur above the water table where the pressure head is negative (absolute pressure can never be negative, but gauge pressure can) and the water that incompletely fills the pores of the aquifer material is under suction. (wikipedia.org)
  • dialysis
  • These include frequency (how many treatments per week), length of each treatment, and the blood and dialysis solution flow rates, as well as the size of the dialyzer. (wikipedia.org)
  • small
  • Small pores are critical for water retention and help a crop endure dry periods with minimal yield loss. (wikipedia.org)
  • filtration
  • This significantly increases the filtration ability of the medium in comparison to other types of filtration processes and allows particles of different sizes to be filtered in the matrix. (wikipedia.org)
  • As the contaminant separation process takes place in the filter medium, factors such as flocculation time, filtration velocity and flocculent dosage are required to be monitored regularly, as they can directly affect the flocculent size produced. (wikipedia.org)
  • critical
  • But as they say, an ounce of prevention is worth a pound of cure and in this case, to prevent acne or acne scarring, controlling pore size may be critical to maintaining beautiful, clear skin! (americanhealthandbeauty.com)
  • found
  • Pores are the air pockets found in leavened bread, where carbon dioxide from the fermentation process creates a network of primarily interconnected void structures. (wikipedia.org)
  • exchange
  • Large pores drain rapidly and are needed for good air exchange during wet periods, preventing oxygen deficiency that can drown plants and increase pest problems. (wikipedia.org)
  • segments
  • The fifth and sixth transmembrane segments (S5 and S6) and pore loop serve the principal role of ion conduction, comprising the gate and pore of the channel, while S1-S4 serve as the voltage-sensing region. (wikipedia.org)
  • In classical systems, they were placed in the order Opisthopora, on the basis of the male pores opening posterior to the female pores, though the internal male segments are anterior to the female. (wikipedia.org)
  • sixth
  • it is incoherent and the resulting intensity is just the sum of the squares of the amplitudes from each particle and therefore proportional to the inverse fourth power of the wavelength and the sixth power of its size. (wikipedia.org)
  • Volume
  • As hydrogen is fundamentally associated to the amount of water and/or oil present in the pore space, measurement of neutron population within the investigated volume is directly linked to porosity. (wikipedia.org)
  • With the various substitutions, the equation becomes: D P = 1470 kPa ⋅ μ m P L {\displaystyle D_{P}={\frac {1470\ {\text{kPa}}\cdot \mu {\text{m}}}{P_{L}}}} As pressure increases, so does the cumulative pore volume. (wikipedia.org)
  • pressure
  • Correction parameters for lithology, borehole parameters, and others are necessary for accurate porosity determination as follow: Borehole size Borehole salinity Borehole temperature and pressure Mud cake Mud weight Formation salinity Tool standoff from borehole wall Subject to various assumptions and corrections, values of apparent porosity can be derived from any neutron log. (wikipedia.org)
  • Common causes of landslides include: i) presence of weak geological layers, ii) overpressure due to rapid accumulation of sedimentary deposits, iii) earthquakes, iv) storm wave loading and hurricanes, v) gas hydrate dissociation, vi) groundwater seepage and high pore water pressure, vii) glacial loading, viii) volcanic island growth, and ix) oversteepening. (wikipedia.org)
  • Earthquakes provide significant environmental stresses and can promote elevated pore water pressure which leads to failure. (wikipedia.org)
  • If pore water flow is impeded then this gas charging leads to excess pore water pressure and decreased slope stability. (wikipedia.org)
  • Groundwater seepage and elevated pore water pressure can cause submarine landslides. (wikipedia.org)
  • Elevated pore water pressure causes reduced frictional resistance to sliding and can result from normal depositional processes, or can be coupled with other causes such as earthquakes, gas hydrate dissociation and glacial loading. (wikipedia.org)
  • However, at sufficiently low pressure, the distance between collisions exceeds the size of the vessel, and then the conductivity does reduce with pressure. (wikipedia.org)
  • length
  • The size of a scattering particle is often parameterized by the ratio x = 2 π r λ {\displaystyle x={\frac {2\pi r}{\lambda }}} where r is its characteristic length (radius) and λ is the wavelength of the light. (wikipedia.org)
  • The subspecies also differ from one another in their hairiness, spine length and width, and the size of the grooming claws on their hind feet. (wikipedia.org)
