The motoneurons present in the ventral horn on the ipsilateral and contralateral sides to the injury were counted in alternate sections of each specimen in the injured area of the lumbar intumescence. Only cells with visible nuclei were counted.
In some cases, the intumescence of host organs results only from parenchyma hyperplasia (Goodey, 1948; Ferreira et al., 2017a).
Foliar intumescence may develop in the absence of ultraviolet light spectra, and this and other less understood stimuli could seriously limit some crops lighted solely by narrow-band light-emitting diodes.
A whitish multinodular irregular soft mass involving the meninges and compressing the spinal cord from the lumbar intumescence to the sacral region was observed.

Among the characteristics necessary to guarantee the quality of the vegetal material, the recommendations of the Brazilian Pharmacopoeia were followed: foreign material, loss on drying, particle size, total and sulfated ashes, foam index, intumescence index, and hemolytic assay [12].
Overall, the agreement with the measured results is very good, considering the complex physical and chemical behaviour of the intumescence process and many of the necessary assumptions may not be exact.
LEED- specified buildings, as well as those desirous of greater mold control, termite control, intumescence, hurricane resistance and basic structural protection are driving conventional technologies to incorporate higher performance standards.

(11-13) However, the fireproof coating composed of APP-MEL-PER and polymer binder cannot provide sufficient protection over a long time in a fire because of two factors: (1) the char layer formed by the APP-MEL-PER coating can be easily oxidized and detached from the substrate material at high temperatures, (14,15) which has significant impact on the performance of the coating and increases the risk of structural failure of the element; and (2) the nonflammable gases (such as [H.sub.2]O, N[H.sub.3], and C[O.sub.2]) produced by fire retardant additives can easily escape from the melting char during the intumescence of the coating at high temperature.
The socalled border cells (spinal cord segments [L.sub.1] to [L.sub.7]) are largely responsible for tonic inhibition of extensor muscle alpha motoneurons in cervical intumescence. This thoracic limb hypertonicity usually subsides after 10 to 14 days.
