| dissociation | 1. The act of separating or state of being separated. 2. <chemistry> The separation of a molecule into two or more fragments (atoms, molecules, ions or free radicals) produced by the absorption of light or thermal energy or by solvation. 3. <psychology> A defense mechanism in which a group of mental processes are segregated from the rest of a person's mental activity in order to avoid emotional distress, as in the dissociative disorders or in which an idea or object is segregated from its emotional significance, in the first sense it is roughly equivalent to splitting, in the second, to isolation. 4. A defect of mental integration in which one or more groups of mental processes become separated off from normal consciousness and, thus separated, function as a unitary whole. Origin: L. Sociatio = union (18 Nov 1997) |

| dissociation by interference | The simultaneous operation of two separate cardiac pacemaking foci that are unassociated because of interference (a normal physiologic phenomenon) due to rendering their respective territories refractory to each other. Usually atrioventricular dissociation is indicated, the rates being quite close to each other with the atrial rate slightly faster than that of the pacemaker in control of the ventricles. Capture is in either direction, usually the ventricle by the atrium, in incomplete dissociation. H Synonym: dissociation by interference. (05 Mar 2000) |
| dissociation constant | <chemistry> In a chemical equilibrium of form A + B = AB, the equilibrium concentrations (strictly, activities) of the reactants are related such that A x B/AB = a constant, Kd, the dissociation constant, that in this simplest case has the dimensions of concentration. When A is H, this is the acid dissociation constant often designated Ka and expressed as pKa (log10Ka). (18 Nov 1997) |
| dissociation constant of a base | Expressed by the general equation [B+][OH-]/[BOH] = Kb, where BOH is the undissociated base. (05 Mar 2000) |
| dissociation constant of an acid | Expressed by general equation [H+][A-]/[HA] = Ka, where HA is the undissociated acid. (05 Mar 2000) |
| dissociation constant of water | Expressed by the equation [H+][OH-] = Kw = 10-14 at 25°C. (05 Mar 2000) |
| dissociation sensibility | The loss of the pain and the thermal senses with preservation of tactile sensibility or vice versa. (05 Mar 2000) |
| acid dissociation constant | <chemistry> This is the equilibrium constant for the breaking apart of a weak acid into its hydrogen and conjugate base in a water solution. (09 Oct 1997) |
|---|---|
| albuminocytologic dissociation | Increased protein in the cerebrospinal fluid without increase in cell count, characteristic of the Guillain-Barre syndrome; it is also associated with spinal block and with intracranial neoplasia, and is seen in the last phases of poliomyelitis. (05 Mar 2000) |
| atrial dissociation | Mutually independent beating of the two atria or of parts of the atria. (05 Mar 2000) |
| atrioventricular dissociation | Any situation in which atria and ventricles are activated and contract independently, as in complete A-V block, more specifically, the dissociation between atria and ventricles that results from slowing of the atrial pacemaker or acceleration of the ventricular pacemaker at nearly equal (rarely equal) rates, each depolarising its own chamber, thus interfering with depolarisation by the other (interference-dissociation). (05 Mar 2000) |
| A-V dissociation | Any situation in which atria and ventricles are activated and contract independently, as in complete A-V block, more specifically, the dissociation between atria and ventricles that results from slowing of the atrial pacemaker or acceleration of the ventricular pacemaker at nearly equal (rarely equal) rates, each depolarising its own chamber, thus interfering with depolarisation by the other (interference-dissociation). (05 Mar 2000) |
| base dissociation constant | <chemistry> This is the equilibrium constant for the reaction in which a weak base breaks apart in water to form its conjugate acid and hydroxide ion. (09 Oct 1997) |
| bond dissociation energy | This is the energy needed to break the bonds between two linked atoms. (09 Oct 1997) |
| molecular dissociation theory | A theory, pertaining to colour vision, that gray is the earliest of colour sensations, from which are derived, by molecular change, two paired substances that, respectively, detect yellow and blue, and that the yellow gives rise to paired substances for detection of red and green. Synonym: Ladd-Franklin theory. (05 Mar 2000) |
| complete atrioventricular dissociation | A-V dissociation not interrupted by ventricular captures. Synonym: complete A-V block. (05 Mar 2000) |
| heat of dissociation | The heat (expressed in calories or joules) expended in the dissociation of 1 mol of a substance into specified products. (05 Mar 2000) |
| pupillary light-near dissociation | A stronger near pupil response than light response; due to weak pupillomotor input, Argyll Robertson pupil, dorsal midbrain syndrome, or to misdirection of ciliary muscle fibres into the iris sphincter. Synonym: light-near dissociation. (05 Mar 2000) |
| sleep dissociation | <neurology, physiology> A condition that occurs in REM stage sleep. There is no movement of the skeletal muscles in this stage of sleep. See: REM stage sleep. (27 Sep 1997) |
| syringomyelic dissociation | Loss of pain and temperature sensation with relative retention of tactile sensation, related to a cavity in the central portion of the cord interrupting the decussation of nerve fibres. (05 Mar 2000) |
| incomplete atrioventricular dissociation | A-V dissociation interrupted by ventricular captures. (05 Mar 2000) |
| interference dissociation | The simultaneous operation of two separate cardiac pacemaking foci that are unassociated because of interference (a normal physiologic phenomenon) due to rendering their respective territories refractory to each other. Usually atrioventricular dissociation is indicated, the rates being quite close to each other with the atrial rate slightly faster than that of the pacemaker in control of the ventricles. Capture is in either direction, usually the ventricle by the atrium, in incomplete dissociation. H Synonym: dissociation by interference. (05 Mar 2000) |
| dissociation |
the act of removing from association a state in which some integrated part of a person's life becomes separated from the rest of the personality and functions independently (chemistry) the temporary or reversible process in which a molecule or ion is broken down into smaller molecules or ions

| dissociation |
The process in which a molecule is broken into two fragments by rupture of a chemical bond. The dissociation may occur via a thermal process, or following the absorption of a photon (photodissociation).

| dissociation constant |
Tendency of a complex to dissociate. The smaller the Kd, the less likely is dissociation.

| dissociation |
A psychological separation of "splitting off"; an intrapsychic defensive process, which operates automatically and unconsciously. Through its operation, emotional significance and affect are separated and detached from an idea, situation, or object.
