Pyrimidine Derivatives and Purine Bases in Soils
In earlier papers the presence of protein decomposition products in soils was reported and it was shown that in soils the changes occurring in the decay of such plant and animal materials as get into the soil are similar to the changes occuring under other conditions in the laboratory or in nature. The presence of arginine and histidine in soils was definitely established by isolating these deg...

متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
