Influence of Urea and Ammonium Sulfate on Soil Acidity Indices in Lowland Rice Production
(TAYLOR & FRANCIS INC, 2010)
Urea and ammonium sulfate are principal nitrogen (N) sources for crop production. Two field experiments were conducted during three consecutive years to evaluate influence of urea and ammonium sulfate application on grain ...
Effect of disinfectant agents on dimensional stability of elastomeric impression materials.
(1999-05-01)
STATEMENT OF PROBLEM: Difficulties in sterilizing impressions by traditional methods have led to chemical disinfection as an alternative, and some studies have shown that disinfectants may adversely affect impressions. ...
Marginal fit of nickel-chromium copings before and after internal adjustments with duplicated stone dies and disclosing agent.
(2000-06-01)
STATEMENT OF PROBLEM: Despite careful procedures, master stone dies may be damaged during laboratory procedures. The dentist routinely adjusts castings because the marginal fit of casting is not as accurate as on the dies. ...

HEPARAN-SULFATE PROTEOGLYCAN AND CONTROL OF CELL-PROLIFERATION - ENHANCED SYNTHESIS INDUCED BY PHORBOL ESTER (PMA) DURING G(1)-PHASE
(Assoc Bras Divulg Cientifica, 1994-09-01)
The effect of phorbol 12-myristate-13-acetate (PMA), a tumor-promoting phorbol ester, on the synthesis of proteoglycans of endothelial cells in culture was investigated. This phorbol activates protein kinase C (PKC) when ...
