These nodes are areas where the action potential is amplified using a high density of sodium ( Na < big >+</ big >) ions and is subsequently passed along the axon.

These pores cross both of the membranes, providing a channel that allows free movement of small molecules and ions.

These types of substitutional defects are often referred to as off-center ions.

These channels are gated so they can open and close, thus regulating the flow of ions or small polar molecules.

These substances, major constituents of bauxite, are known as laterites and are formed by leeching from rocks of most of the ions other than aluminium and iron and subsequent hydrolysis of the remaining aluminium and iron.

These ions are then attracted to each other in a 1: 1 ratio to form sodium chloride ( NaCl ).

These freed electrons and ions are in turn accelerated and strike other atoms, creating more charge carriers, in a chain reaction.

These ions move through the channel pore single file nearly as quickly as the ions move through free fluid.

These discharges were found to be formed by both negative nitrogen ions and positive oxygen ions.

These charged particles ( ions ) are found in the fluid that surrounds the entire nervous system.

These include ion channels that permit electrically charged ions to flow across the membrane, and ion pumps that actively transport ions from one side of the membrane to the other.

These signals are generated and propagated by charge-carrying ions including sodium ( Na < sup >+</ sup >), potassium ( K < sup >+</ sup >), chloride ( Cl < sup >-</ sup >), and calcium ( Ca < sup > 2 +</ sup >).

These component ions can be inorganic such as chloride ( Cl < sup >−</ sup >), as well as organic such as acetate ( CH < sub > 3 </ sub > COO < sup >−</ sup >) and monatomic ions such as fluoride ( F < sup >−</ sup >), as well as polyatomic ions such as sulfate ( SO < sub > 4 </ sub >< sup > 2 −</ sup >).

These atoms can also turn into ions and electrons if they reach a certain temperature.

These ions are charge balanced by cations of sodium in the natural material.

These ions are removed by injecting a collisional gas ( He ), or a reactive gas ( H < sub > 2 </ sub >), or a mixture of the two, directly into the plasma as it flows through the skimmer cone and / or the sampler cone.

These proteins would then intervene the rapid upstroke of an action potential, thus allowing a flow of sodium ions into neurons.

These membrane proteins can perform a wide diversity of functions, such as transporting ions and molecules across the red cell membrane, adhesion and interaction with other cells such as endothelial cells, as signaling receptors, as well as other currently unknown functions.

These cations, such as the tetra-n-butylammonium cation, are sometimes used to replace sodium or potassium ions to increase the solubility of the associated anion in organic solvents.

These assumptions lead to an organization with one man at the top, six directly under him, six under each of these, and so on until there are six levels of personnel.

These proposals would reduce the amount of tax that DuPont stockholders might have to pay -- from an estimated 1.1 billion dollars under present law to as little as 192 million dollars.

These never ceased to suggest that if, in the eyes of Marx and Lenin `` full communism '' was still a very distant ideal, the establishment of a Communist society had now, under Khrushchev, become an `` immediate and tangible reality ''.

These were educated men, who, as Mr. Justice Holmes was fond of saying, formed their inductions out of experience under the burden of responsibility.

These extra-curricular activities are conducted under supervision of the Director of the Student Workshop.

These became `` strays '', the term bein' restricted to cattle, however, as hosses, under like circumstances, were spoken of as `` stray hosses '', not merely `` strays ''.

These men -- for the most part educated in our `` best '' New England colleges, well established financially and socially in the community -- under kindly but insistent probing, reveal little or no objective or explicit criteria or data for their generalizations about the interests and attitudes of the people they claim to serve, or about the public responses that actually follow their occasional breach of a `` client-service relationship ''.

These include Metals and Materials ; the Secrets of Chemistry ; the Origin of Metals ; the Origins of Compounds, and a Concordance which is a collection of Observations on the philosopher's stone ; and other alchemy-chemistry topics, collected under the name of Theatrum Chemicum.

These antigens should, under normal conditions, not be the target of the immune system, but, due to mainly genetic and environmental factors, the normal immunological tolerance for such an antigen has been lost in these patients.

These tests were performed under wet exposure conditions.

These occurrences, along with a Bieda who is mentioned in the Anglo-Saxon Chronicle under the year 501, are the only appearances of the name in early sources.

; Honorary Assistant bishop, Assisting Bishop, or Bishop Emeritus: These titles are usually applied to retired bishops who are given a general licence to minister as episcopal pastors under a diocesan's oversight.

These microcomputers were later manufactured in Kunming, China for use in China under agreement with Burroughs.

These three products all share a common ancestry and are currently under active development at Oracle Corporation.

These churches at first used and then revised the use of the Prayer Book, until they, like their parent, produced prayer books which took into account the developments in liturgical study and practice in the nineteenth and twentieth centuries, which come under the general heading of the Liturgical Movement.

These groups are sometimes classified under denominations, though for theological reasons many groups reject this classification system.

These spherical particles precipitate in highly siliceous pools in Australia and elsewhere, and form these highly ordered arrays after years of sedimentation and compression under hydrostatic and gravitational forces.

These ideas were unified by Kenneth Wilson in 1972, under the formalism of the renormalization group in the context of quantum field theory.

These Greek city-states reached great levels of prosperity that resulted in an unprecedented cultural boom, that of classical Greece, expressed in architecture, drama, science, mathematics and philosophy, and nurtured in Athens under a democratic government.

These continued to dominate throughout the period, but during late Carboniferous, several other groups, Cycadophyta ( cycads ), the Callistophytales ( another group of " seed ferns "), and the Voltziales ( related to and sometimes included under the conifers ), appeared.

These islands are now under Serbian police control.

These are the issue of Royal Prerogative where the reigning monarch may continue to exercise power under certain very limited circumstances, Sovereign Immunity where they are considered to have done no wrong under the law, and may avoid both taxation and planning permission for example, and considerable ceremonial power where the executive, judiciary, police and armed forces owe allegiance to the Crown.
