In most cases, these soils are taken up as liquids through capillary action.

The original Biro pen used capillary action and a piston that pressurised the ink column, solving the ink delivery flow problems.

Later Biro pens had a spring that kept pressure on the piston, and still later the Biro pens used just gravity and capillary action.

Water, via capillary action, goes out from the cracks and freezes on contact with the air.

Passive sub-irrigation, also known as passive hydroponics or semi-hydroponics, is a method wherein plants are grown in an inert porous medium that transports water and fertilizer to the roots by capillary action from a separate reservoir as necessary, reducing labour and providing a constant supply of water to the roots.

Rock wool is made from molten rock, basalt or ' slag ' that is spun into bundles of single filament fibres, and bonded into a medium capable of capillary action, and is, in effect, protected from most common microbiological degradation.

The hollow shaft of the feather ( the calamus ) acts as an ink reservoir and ink flows to the tip by capillary action.

Buffer transfer by capillary action from a region of high water potential to a region of low water potential ( usually filter paper and paper tissues ) is then used to move the DNA from the gel on to the membrane ; ion exchange interactions bind the DNA to the membrane due to the negative charge of the DNA and positive charge of the membrane.

Large marshy salt flats, formed by capillary action in the soil, exist in many depressions, including the Garaşor, which occupies 1, 500 square kilometers in the northwest.

* Leonardo da Vinci observes capillary action in small-bore tubes.

A fill blade or squeegee is moved across the screen stencil, forcing or pumping ink into the mesh openings for transfer by capillary action during the squeegee stroke.

The ink that is in the mesh opening is pumped or squeezed by capillary action to the substrate in a controlled and prescribed amount, i. e. the wet ink deposit is proportional to the thickness of the mesh and or stencil.

This flame provides sufficient heat to keep the candle burning via a self-sustaining chain of events: the heat of the flame melts the top of the mass of solid fuel, the liquefied fuel then moves upward through the wick via capillary action, and the liquefied fuel is then vaporized to burn within the candle's flame.

A candle wick works by capillary action, drawing (" wicking ") the melted wax or fuel up to the flame.

The primary force that creates the capillary action movement of water upwards in plants is the adhesion between the water and the surface of the xylem conduits.

By capillary action, the water forms concave menisci inside the pores.

Transpiration pull, utilizing capillary action and the inherent surface tension of water, is the primary mechanism of water movement in plants.

The water content in the unsaturated zone is held in place by surface adhesive forces and it rises above the water table ( the zero gauge pressure isobar ) by capillary action to saturate a small zone above the phreatic surface ( the capillary fringe ) at less than atmospheric pressure.

It may also be said to be due to combustion, capillary action, or Marangoni and Weissenberg effects.

The Royal Society was founded in 1660, and in April 1661 the society debated a short tract on the rising of water in slender glass pipes, in which Hooke reported that the height water rose was related to the bore of the pipe ( due to what is now termed capillary action ).

He also observed the constancy of the angle of contact of a liquid surface with a solid, and showed how from these two principles to deduce the phenomena of capillary action.

In 1805, Pierre-Simon Laplace, the French philosopher, discovered the significance of meniscus radii with respect to capillary action.

Capillary blood sampling is generally performed by creating a small cut by a blood lancet, followed by sampling by capillary action on the cut with a test strip or small pipe.

The term ' northern blot ' actually refers specifically to the capillary transfer of RNA from the electrophoresis gel to the blotting membrane.

Capillary action, capillarity, capillary motion, or wicking refers to two phenomena:

Starling's equation only refers to fluid movement across the capillary membrane that occurs as a result of filtration.

Because large plasma proteins cannot easily cross through the capillary walls, their effect on the osmotic pressure of the capillary interiors will, to some extent, balance out the tendency for fluid to leak out of the capillaries.

Because the hydrophilic and closely spaced cellulose fibers of the paper provide traction for capillary action, water and wet paint have a strong tendency to migrate from wetter to drier surfaces of the painting.

This is achieved by curbing the paper fibers ' tendency to absorb liquids by capillary action.

In the simplest method, the pot sits in a shallow solution of fertilizer and water or on a capillary mat saturated with nutrient solution.

The Soviet physicist Nikolai Fedyakin, working at a small government research lab in Kostroma, Russia, had performed measurements on the properties of water that had been condensed in, or repeatedly forced through, narrow quartz capillary tubes.

Impact from a water drop causes an upward " rebound " jet surrounded by circular capillary wave s.

These factors lead to strong attractive forces between molecules of water, giving rise to water's high surface tension and capillary forces.

The capillary rise of water in a small diameter tube is this same physical process.

Salts can be transported to the soil surface by capillary transport from a salt laden water table and then accumulate due to evaporation.

Most water leakage occurs in capillaries or post capillary venules, which have a semi-permeable membrane wall that allows water to pass more freely than protein.

Certain frost-susceptible soils expand or heave upon freezing as a result of water migrating via capillary action to grow ice lenses near the freezing front.

The lymph fluid has been found to move through a lymph capillary of the skin at approximately 0. 0000097 m / s.

Heat pipes use latent heat and capillary action to move heat, and can carry many times as much heat as a similar-sized copper rod.

Analysers that measure plasma viscosity commonly work by drawing a small sample of plasma through a narrow capillary using a constant pressure and measuring the time taken for the sample to move a

A loop heat pipe ( LHP ) is a two-phase heat transfer device that uses capillary action to remove heat from a source and passively move it to a condenser or radiator.

It is typically formed by the accumulation of soluble minerals deposited by mineral-bearing waters that move upward, downward, or laterally by capillary action, commonly assisted in arid settings by evaporation.

If capillary waves are assumed to generate the momentum transfer to the water, the animal's legs must move faster than the phase speed of the waves, given by
