(n.) The measurement of the force of solar radiation.
(n.) The measurement of the chemical or actinic energy of light.
Example Sentences:

(4) Therefore, it is considered feasible to simulate the photo-stability of KBT-3022 in aqueous solutions containing acetonitrile by exposure to all other light sources including diffuse daylight, if the cumulative number of photons of the light can be determined by actinometry.
(5) Actinometry of devices for ultraviolet irradiation of blood for the first time.
Heating
Definition:
(p. pr. & vb. n.) of Heat
(a.) That heats or imparts heat; promoting warmth or heat; exciting action; stimulating; as, heating medicines or applications.
Example Sentences:
(1) Tryptic digestion of the membranes caused complete disappearance of the binding activity, but heat-treatment for 5 min at 70 degrees C caused only 40% loss of activity.
(2) A new and simple method of serotyping campylobacters has been developed which utilises co-agglutination to detect the presence of heat-stable antigens.
(3) The 40 degrees C heating induced an increase in systolic, diastolic, average and pulse pressure at rectal temperature raised to 40 degrees C. Further growth of the body temperature was accompanied by a decrease in the above parameters.
(4) The effect of heat on glucocorticoids of plasma was not significant.
(5) This Mr 20,000 inhibitory activity was acid and heat stable and sensitive to dithiothreitol and trypsin.
(6) There is a relationship between the duration of stimulation (t) and the total heat production (H) of the type H = A plus bt, where A and b are constants.
(7) This suggests that there was a deterioration of the vasoconstrictor response and indicated a possible effect of heat at the receptor or effector level.
(8) While both inhibitors caused thermosensitization, they did not affect the time scale for the development of thermotolerance at 42 degrees C or after acute heating at 45 degrees C. The inhibitors of poly(ADP-ribosylation) radiosensitizers and thermosensitizers may be of use in the treatment of cancer using a combined modality of radiation and hyperthermia.
(9) The binding to DNA-cellulose of heat-activated [3H]RU486-receptor complexes was slightly decreased (37%) when compared with that of the agonist [3H]R5020-receptor complexes (47%).
(10) By means of rapid planar Hill type antimony-bismuth thermophiles the initial heat liberated by papillary muscles was measured synchronously with developed tension for control (C), pressure-overload (GOP), and hypothyrotic (PTU) rat myocardium (chronic experiments) and after application of 10(-6) M isoproterenol or 200 10(-6) M UDCG-115.
(11) The return of NE to normal levels after one month is consistent with the observation that LH-lesioned rats are by one month postlesion no longer hypermetabolic, but display levels of heat production appropriate to the reduced body weight they then maintain.
(12) It is the action of this protease that releases the enzyme from the membrane, as shown by the observations that protease inhibitors decreased the amount of solubilization of the enzyme, and the enzyme remaining in the membrane after heating showed much less proteolytic cleavage than that which was released.
(13) The apparent sensitivity of Escherichia coli K12 to mild heat was increased by recA (def), recB and polA, but not by uvrA, uvrB or recF mutations.
(14) Michele Hanson 'The heat finally broke – I realised something had to change …' Stuart Heritage (right) with his brother in 2003.
(15) The data suggest that inhibition of gain in weight with the addition of pyruvate and dihydroxyacetone to the diet is the result of an increased loss of calories as heat at the expense of storage as lipid.
(16) Induction of both potential transcripts follows heat shock in vivo.
(17) Lebedev punched Polonsky during a heated early recording of NTVshniki.
(18) At the site of injury heat itself causes microvascular damage.
(19) Acid-fast bacilli were isolated from 3 out of 41 mice inoculoted with heat killed bacilli.
(20) Mean run time and total ST time were faster with CE (by 1.4 and 1.2 min) although not significantly different (P less than 0.06 and P less than 0.10) from P. Subjects reported no significant difference in nausea, fullness, or stomach upset with CE compared to P. General physiological responses were similar for each drink during 2 h of multi-modal exercise in the heat; however, blood glucose, carbohydrate utilization, and exercise intensity at the end of a ST may be increased with CE fluid replacement.
