(n.) The number from which another number is to be subtracted.
Example Sentences:
(1) The present study evaluated two procedures, Stimulus Manipulation and Delay Feedback Only, for teaching difficult-to-teach students to solve missing minuend problems (i.e., missing number problems starting with a minus sign).
Summation
Definition:
(v. t.) The act of summing, or forming a sum, or total amount; also, an aggregate.
Example Sentences:
(1) Alphaxalone and endogenous steroid hormone metabolites inhibit the binding of [35S]-t-butyl bicyclophosphorothionate in some regions, enhance it in others and give biphasic concentration-dependence in others, apparently the result of algebraic summation of two effects involving regional-dependent enhancement or inhibition.
(2) This suggests that the curvature of the xenon clearance curve is the result of recording the summation of the activities from the alveoli and the pulmonary blood and not, as previously described, due to the existence of two different sub-populations of alveoli.
(3) Left ventricular cavity and muscle areas of each image were planimetered with a light-pen system and summated for volume: total volume = sigma (areas x 3 mm).
(4) The computer system was a hybrid of analog devices (tape-recorder, voltage summator, and high-pass filters) and a multipurpose laboratory digital device (PDP-12).
(5) Spatial summation was found to decrease by 30-50% as the cell was light-adapted to a threshold some 4 log units above the dark-adapted one.
(6) The findings strongly suggest the existence of spatial summation of the effects from GM and TA muscle at the level of a single interneuronal pool.
(7) The parameters mainly related to temporal summation are not different between various electrode configurations.
(8) Therefore, anopic observers usually need a very large amount of spatial summation to arrive at a well defined match of the projection anomaloscope.
(9) This model corresponds to quadratic summation of the stimulus followed by a random threshold device.
(10) Consequently, the slow repolarization transients of succeeding receptor potentials displayed temporal summation.
(11) Thus the relation of neuron geometry to aspects of spatiotemporal summation of synaptic inputs can be investigated readily.
(12) The summation of findings suggests that endogenous substance P plays a complementary role in the regulation of parasympathetic nerve-induced fluid secretion in the acinus but is minimally involved in degranulation from granular duct cells.
(13) These estimates can be summated to provide total ventricular and total brain volumes.
(14) This effect of parathyroid hormone, which appears to involve more than simple physiologic summation, may have important clinical implications.
(15) At frequencies above 15 Hz the SETi-evoked contraction dominates tension development, though IR summates with it during the rising phase.
(16) At reoperation because of dehiscence and hematoma interval between two operation is very short so we have got present not only hypovolemia but also summation effect of used anesthetic and plasma expander.
(17) The stimulant effects of amantadine and d-amphetamine summated but did not interact, response rates after d-amphetamine being augmented by pretreatment with amantadine except at intervals at which amantadine was by itself depressant.
(18) The laminar pattern of current sources and sinks coincident with this component was more complicated after bicuculline, reflecting the summation of current flows associated with disinhibited lamina 4 activity.
(19) The cochlear summating potential (SP) preceding the auditory nerve compound action potential (AP) was elicited by broadband alternating condensation and rarefaction clicks and recorded by noninvasive electrodes from the external auditory meatus (EAM) of 60 volunteers of both sexes, 12 to 67 years old, who had normal hearing for age.
(20) It is wiser, in the light of results reporting individual differences in the existence and extent of the paradox, and its sensitivity to stimulus conditions, to side with Blake and Fox (1973) when they observed that it is not unreasonable to suppose that various stimulus conditions might yield varying amounts of summation or even inhibition.
