This can lead to bloody mucus in nose areas when the blood resulting from this minimal trauma is mixed in with regular clear mucus. And, when blood dries, mucus color can change again, becoming tinged with shades of brown or dark red when dislodged from the nasal area. Therefore brown mucus from nose areas is not uncommon during times of illness or other nose maladies.
Soil Compaction Tests. There are many types of Soil compaction tests which are performed on soil. One of the most common test to determine the field density of soil is the sand-cone method. Maximum density is found by plotting a densityâmoisture curve.
The study focused on a natural phenomenon that may counteract the effect of soil compaction: the annual freezing and thawing of soil during the regionâs severe winters and warmer springs. The researchers measured compaction at several soil depths in two types of plots. One plot was kept above freezing, and the other was subjected to several freeze-thaw cycles (FTCs). A farm truck with a single rear axle was loaded to the maximum legal weight to simulate a truck at harvest. Soil plots were compacted by driving the truck over them in several overlapping passes.
