What does NOT require gravity for its formation?
Capillary Fringe
What is the function of astrocytes cells?
Astrocytes are star shaped glial cells because of cytoplasmic processes that extend from the cell body. They play a role in regulating the extracellular composition of brain fluid. They release chemicals that promote the formation of tight junctions between the endothelial cells of capillaries.
What is permeability in electromagnetism?
Permeability is the measure of the ability of a material to support the formation of a magnetic field within itself.(Degree of magnetization that a material obtains in response to an applied magnetic field.) It is represented by the Greek letter μ.
What is an aquiclude?
A geologic formation that contains water which is not easily extractable for use, because of the low permeability of the formation's constituent material.
How can man increase porosity and permeability in oil wells?
There is not feasible way to change the overall porosity and permeability in an oil field. However, it is possible in many cases to improve the porosity and permeability within the near wellbore region, where the change in pressure is the greatest. Injecting acid into a well, may slightlyincrease the porosity but sigmificantly improve the permeability, as it creates larger flow paths (also called worm holes) through the formation. Hydraulic fracturing will also stimulate a well, although the formation's permeability and porosity is unchanges. It makes it easier for oil to flow into the well, so its effect in the long run, is the same as if the near well bore region had higher permeability. Low permeability formations often produced by horizontal wells, which is similar to hydraulic fracturing- it is easier for the oil to flow to the well.

1 What characteristics of a rock layer allow it to hold water?
Permeability is the ability of that water to be transmitted from one place to another. For example clays have a huge porosity, but very bad permeability. Secondary permeability is the measure of other physical structures in a rock or admixture that allows for storage of water in spaces not primary to the fabric of the formation.
What is cappillarization?
The word "cappillarization" is used to indicate the formation and development of a network of capillary blood vessels to some part of the body
What is High permeability vs low permeability?
Permittivity (ε) applies to electric fields, and permeability (μ) refers to magnetic fields.In electromagnetism, permeability is the measure of the ability of a material to support the formation of a magnetic field within itself AND permittivity is the measure of how much resistance is encountered when forming an electric field in a medium.Also their relation is given byv= 1----1/2(ε*μ)v=velocity of light.
What are 3 things to look for to determine if a chemical change was produced in the experiment?
change in temperature, formation of a gas, formation of a solid
Which of these determine a person's blood type and stimulate antibody formation?
antigens A+ (:
What is formation damage in the oil and gas industry?
Formation DamageFormation Damage can be defined as, "a reduction in permeability around a well bore, which is the consequence of drilling, completion, injection, attempted stimulation or production of that well."Formation Damage can cause significant decreases in well productivity and worldwide yearly lost production due to Formation Damage is equivalent to billions of dollars in lost revenue. Identification and reduction of Formation Damage problems can lead to immediate returns .
