A comprehensive analysis of the MC indicated that average initial MC was affected by the tree harvesting season and
pith location.
Then 1-inch-thick boards were sawn parallel to the
pith from each cant outward to 4 inches from the
pith, with the middle board centered on the
pith.
For certain species, such as plantation teak, a modified sawing pattern could be used to eliminate large objectionable
pith centers.
These measurements were made to obtain the radial variation in the GA from the
pith to the bark and to verify measurements made on trees and on logs.
In the end, Pointy Shoes and
Pith Helmets is a valuable contribution to the study of Ambonese, Indonesian, and colonial history that fascinates from beginning to end.
The mean value of the TL gradually increased up to the 18th annual ring from the
pith, and then it showed an almost constant value (Fig.
After the abovementioned parameters were determined, the effective degradability of DM, NDF, and ADF in whole plant, leaf blade, leaf sheath, stem rind, stem
pith, stem node, ear husk, and tassel of corn stover were calculated using the equation described by 0rskov and McDonald (1979) as follows:
Pith helmets come in different shapes from various regiments.
Therefore, it appears that the gas production parameters and degradability of sugarcane
pith by rumen microbial fractions are influenced by low temperature steam and sulfuric acid treatment, bacterial group generates a larger volume of gas production than fungal or protozoan group and this method had no negative effect on rumen microorganisms.
The severity and type of damage lowering the internal quality of log (i.e., color defects and/or decay) were classified into 5 grades: 1 = no damage (no visible color defects or decay); 2 = color defect in
pith with a diameter <20 mm (slight color change); 3 = hard rot in
pith with a diameter <20 mm (clear color change, usually as a result of chemical reaction or preliminary stage of decay); 4 = hard rot (the wood material dark but still hard, a condition caused by an infection related to a decaying fungus); 5 = soft rot (wood material is dark and soft, and wears away when scratched) (see Schatz et al.
These cores often contain the
pith, or center of the log, which doesn't accept pressure treatment as well.
Pith is cut from the inner spongy tissue of a small tree, Tetrapanax Papyrifera, which is native to south-west China and Taiwan.
