What's the difference between convection and transmission?

Convection


Definition:

  • (n.) The act or process of conveying or transmitting.
  • (n.) A process of transfer or transmission, as of heat or electricity, by means of currents in liquids or gases, resulting from changes of temperature and other causes.

Example Sentences:

  • (17) Both theoretical and experimental evidence indicates that only the first of these mechanisms could result in the steady-state caloric response that is observed in the absence of convection (e.g., in spaceflight and after canal plugging) and that contributes to the prone-supine asymmetry seen in caloric testing.
  • (18) The dead spaces for hydrogen and sulfur hexafluoride are predicted from the solution of a partial differential equation, applied to Weibel's morphometric data of the lung, and including longitudinal convection and diffusion coupled with instantaneous radial diffusion.
  • (19) It is concluded that in the conditions of the experiments convective mixing by the cardiac action played an insignificant role in promoting intrapulmonary mixing and transport.

Transmission


Definition:

  • (n.) The act of transmitting, or the state of being transmitted; as, the transmission of letters, writings, papers, news, and the like, from one country to another; the transmission of rights, titles, or privileges, from father to son, or from one generation to another.
  • (n.) The right possessed by an heir or legatee of transmitting to his successor or successors any inheritance, legacy, right, or privilege, to which he is entitled, even if he should die without enjoying or exercising it.

Example Sentences:

  • (1) The present results provide no evidence for a clear morphological substrate for electrotonic transmission in the somatic efferent portion of the primate oculomotor nucleus.
  • (2) It has been shown by LM and transmission electron microscopy that cells with blebs are viable and capable of mitotic activity.
  • (3) The presently available data allow us to draw the following conclusions: 1) G proteins play a mediatory role in the transmission of the signal(s) generated upon receptor occupancy that leads to the observed cytoskeletal changes.
  • (4) The transmission of alcoholism and its effects are thereby lessened for future generations of children of alcoholics.
  • (5) Transmission electron microscopy demonstrated that these blebs were devoid of organelles and microvilli; scanning electron microscopy revealed that the blebs were highly wrinkled and more numerous than were the projections observed in tissue from animals treated with testosterone alone, or in tissue from unoperated controls.
  • (6) The intent of this study was to investigate, by three-dimensional photoelastic analysis, the stress transmission that occurs with four commonly used retentive systems.

  • (8) These results indicate that both racemic and L-baclofen inhibit trigeminal transmission in man, probably because they interfere with excitatory transmission through the interneurons of the lateral reticular formation.
  • (9) Substance P, a potent vasodilating peptide, seems to be released from trigeminal nerve endings in response to nervous stimulation and is involved in the transmission of painful stimuli within the periphery.
  • (10) Neuromuscular transmission was measured using "train-of-four" stimulation.
  • (11) Such identification would have a useful application in affirming the possible zoonotic transmission of animal source Giardia species to humans.
