Scanning electron microscopic and profilometric study of different sharpening stones
(2006-12-01)
Scaling and root planing contribute to the recovery of periodontal health. All periodontal instruments loose their fine cutting angle after use. To maintain this angle, correct sharpening is required using specifically ...

Sources and doses of aluminum in experiments with rice in nutrient solution
(Univ Federal Campina Grande, 2019-07-01)
The aluminum source to produce toxicity in upland rice in nutrient solution experiments is not yet well established, althought the aluminum potassium sulfate has been utilized source to produce aluminum toxicity. However, ...
Desidrogenação do etilbenzeno sobre compostos de ferro e alumínio
(2003)
Chromium and potassium-doped iron oxides are widely used as industrial catalysts in the dehydrogenation of ethylbenzene to produce styrene. They have several advantages but deactivate with time, because of the loss of ...
