Manganese micro-nodules on ancient brick walls.
Romans, Jews, Arabs and Christians built the ancient city of Toledo (Spain) with bricks as the main construction material. Manganese micro-nodules (circa 2 microm in diameter) have grown under the external bio-film surface of the bricks. Recent anthropogenic activities such as industrial emissions, foundries, or traffic and housing pollution have further altered these old bricks. The energy-dis...
متن کاملCrystalline todorokite associated with biogenic debris in manganese nodules.
Platy intergrowths of crystalline todorokite are associated with biogenic debris in the cores of manganese nodules from a site in the Pacific Ocean. Analyses by electron diffraction and transmission electron microscopy demonstrate that this material is composed of tunnels of chains of linked MnO(6) octahedra. The chemical composition, morphology, and stability of the todorokite differ from thos...
متن کاملManganese Crusts and Nodules from the Hawaiian Ridge1
Manganese stains, crusts, and nodules are widely distributed on the insular slopes of the Hawaiian ridge. The thickness of the manganese crusts depends on depth of water, water circulation, and the age and lithology of the substrate, and varies from absent to stains off the island of Hawaii to a maximum of 5 cm in the vicinity of Midway. Scanning electron microscope studies indicate that the in...

متن کامل[Bacteriology of leprosy].
In a previous communication (2) a description of an acid-fast organism isolated from human and rat leprous lesions was reported! Embryonic chick tissue-cultures were used as the isolation medium. Later reports (3,4,5) have dealt with the influence of various environmental factors on the tinctorial characteristics of the organisms that were isolated. The present communication deals with results ...
