Appearing regularly in stories published by DC Comics, he debuted in Action Comics # 1 ( June 1938 ) and serves as the civilian and secret identity of the superhero Superman.

# f < sub > ii </ sub > is the identity on A < sub > i </ sub >,

# Any tangent vector at the identity of a Lie group can be extended to a left invariant vector field by left translating the tangent vector to other points of the manifold.

# iff ( identity of indiscernibles ),

# The name in some way reveals the identity of the object.

# The provenance of the document ( identity )

# Finally, individuals diagnosed with DID who are accused of crimes may deny culpability due to the crime being committed by a different identity state.

# The transsexual identity has been present persistently for at least two years

# REDIRECT Euler's identity

# Johann Georg Maximilian von Fürstenhoff ( b. 1686-d. 1753 ), married first to Margareta Dorothea Kühler ( d. 1738 ) and then to a Charlotte Emilie ( who identity is unknown ).

# State name: Many commoners took the name of their state, either to show their continuing allegiance or as a matter of national and ethnic identity.

# By coming out, trans and intersex people disclose their gender identity and, if applicable, their decision to transition to the gender role with which they more closely identify.

# For some trans people who pass and are mistaken for being cisgender, coming out occults important parts of their full sense of identity or their complete gender history.

# It is necessary that 0 ≠ 1, 0 being the additive identity element and 1 being a multiplicative identity element, but this is a nonidentity ;

# REDIRECT Bézout's identity

# The language must admit the rules of identity ( if A, then A ) and modus ponens ( from A, and if A then B, conclude B ).

However, Stern left the series after The Amazing Spider-Man # 252 and subsequent writers struggled with the question of the identity.

Shortly afterwards Peter David ( at the time the regular writer on The Spectacular Spider-Man ) was commissioned to write The Amazing Spider-Man # 289, a double-sized issue in which the Hobgoblin's identity would be revealed.

# The rare earth ions are then selectively washed out by suitable complexing agent.

# For monatomic ions, the OS is the same as the charge of the ion.

# Do not confuse the formal charge on an atom with its formal oxidation state, as these may be different, and often are different, in polyatomic ions.

# When the mole is used, the elementary entities must be specified and may be atoms, molecules, ions, electrons, other particles, or specified groups of such particles.

# Attractive or repulsive electrostatic interactions between permanent charges ( in the case of molecular ions ), dipoles ( in the case of molecules without inversion center ), quadrupoles ( all molecules with symmetry lower than cubic ), and in general between permanent multipoles.

# At least one of the conformations creates a channel through the membrane that is permeable to specific types of ions.

# Calcium ions act on the cytoskeleton to induce the extension of pseudopodia.

# The components of the sample are ionized by one of a variety of methods ( e. g., by impacting them with an electron beam ), which results in the formation of charged particles ( ions )

# The ions are separated according to their mass-to-charge ratio in an analyzer by electromagnetic fields

# The ions are detected, usually by a quantitative method

# The glow of the corona is caused by electrons recombining with positive ions to form neutral atoms.

# Eccrine sweat glands under the skin secrete sweat ( a fluid containing mostly water with some dissolved ions ) which travels up the sweat duct, through the sweat pore and onto the surface of the skin.

# As a result, sodium ions can no longer enter the cell, and the photoreceptor outer segment membrane becomes hyperpolarized, due to the charge inside the membrane becoming more negative.

# the very high ionizing power of heavy ions induces quenching effects which result in a reduced light output ( e. g. for equal energies, a proton will produce 1 / 4 to 1 / 2 the light of on electron, while alphas will produce only about 1 / 10 the light ;

# Accelerated excretion of potassium ions ( K +).

# When calcium is introduced into the muscle cell ( fiber ), calcium ions bind to troponin molecules.

# Upon the arrival of an action potential at the presynaptic neuron terminal, voltage-dependent calcium channels open and Ca < sup > 2 +</ sup > ions flow from the extracellular fluid into the presynaptic neuron's cytosol.

# These receptors are ligand-gated ion channels, and when they bind acetylcholine, they open, allowing sodium ions to flow in and potassium ions to flow out of the muscle's cytosol.

# Glutamate opens NMDA receptors on other neurons which allows calcium ions into the neuron

# Modified for complex atoms and ions by Ammosov et al.

# It degrades the thrust as it is shorting the device and there is current flow through the arc instead of the ions that do the lifting

# REDIRECT Inorganic ions

# Channel formers that introduce a hydrophilic pore into the membrane, allowing ions to pass through while avoiding contact with the membrane's hydrophobic interior.
