| secondary pulmonary lobule | A pyramidal mass of lung tissue whose sides are bounded by the incomplete interlobular connective tissue septa and whose base, which is 1 to 2 cm in diameter, usually faces the pleural surface of the lung; lobule's that occupy a more central position in the lung are not well defined and are considered to consist of three to five pulmonary acini with proximate terminal bronchioles.

| secondary radiation | Secondary radiation emitted from the interaction of X-rays with matter; generally lower in energy, with a directional distribution which depends on the energy of the incident radiation. Synonym: secondary radiation. (05 Mar 2000) |
| secondary rays | X-ray's generated when primary X-ray's impinge upon matter; scattered radiation. (05 Mar 2000) |
| secondary refractory anaemia | Any persistent anaemia that is successfully treated only by blood transfusions, and that is associated with another condition. (05 Mar 2000) |
| secondary reinforcement | Reinforcement through something which, while it does not satisfy the need directly, has been associated with direct satisfaction of the need, such as the effect on behaviour of a food or beer commercial on television. (05 Mar 2000) |
| secondary renal calculus | A calculus associated with infection and/or obstruction, usually composed of struvite (magnesium ammonium phosphate). Synonym: infection calculus. (05 Mar 2000) |
| secondary renal tubular acidosis | Renal tubular acidosis that may occur as a complication of hypercalcaemic states, hyperglobulinaemic disorders, and in some other chronic renal conditions; a regular component of De Toni-Fanconi syndrome. (05 Mar 2000) |
| secondary retinitis | Retinitis that follows uveal inflammation. (05 Mar 2000) |
| secondary saturation | A technique of nitrous oxide anaesthesia consisting of an abrupt curtailment of the oxygen in the inhaled mixture to produce a deep plane of anaesthesia, following which oxygen is administered to correct hypoxia. (05 Mar 2000) |
| secondary screw-worm | An accidental or facultative screw-worm that enters a prior wound or suppurated condition and feeds on infected rather than intact tissues. Many blowflies are included, such as Calliphora vicina, Phaenicia sericata, Phormia regina, Cochliomyia macellaria, Chrysomyia species, and other fleshflies. (05 Mar 2000) |
| secondary sensory cortex | A cortical region occupying the parietal operculum (upper lip of the lateral sulcus) closely posterior to the foot of the postcentral gyrus; like the primary somatic-sensory cortex of the postcentral gyrus, this region receives sensory impulses originating in face, trunk, and limbs; projections to the s.s.c. Are from the ventral basal complex (ventral posteromedial and posterolateral thalamic nuclei) and from the primary somesthetic cortex. (05 Mar 2000) |
| secondary sensory nuclei | Nuclei terminales, collective term indicating those nerve cell groups in the rhombencephalon and spinal cord in which the afferent fibres of the spinal and cranial nerves terminate. Synonym: nuclei terminationis, secondary sensory nuclei. (05 Mar 2000) |
| secondary sex characters | Those character's peculiar to the male or female that develop at puberty, e.g., the beard of men and the breasts of women. (05 Mar 2000) |

| second law of thermodynamics |
An inequality that is fundamentally different from the first law because it specifies the direction in which a natural process will evolve rather than merely requiring that certain quantities are conserved. As formulated by Planck, the second law asserts that a thermodynamic state function, S, known as entropy, exists for all physical systems. ...

(processed) biofuels in the form of solids (e. g. charcoal), liquids (e. g. alcohol, vegetable oil), or gases (e. g. biogas as a mixture of methane and carbon dioxide), can be used for a wider range of applications with higher efficiency rates on average, including transport and high-temperature industrial processes.
