The discovery of functional dependencies from relations is an important database analysis technique. We present TANE, an efficient algorithm for finding functional dependencies from large databases. TANE is based on partitioning the set of rows with respect to their attribute values, which makes testing the validity of functional dependencies fast even for a large number of tuples. The use of p...

BACKGROUND & OBJECTIVE A higher prevalence of periodontal disease among areca nut chewers than non chewers has been demonstrated. Neutrophils, the first line of defence mechanism against microbial infection play an important role in maintaining the periodontal health. In this context our aim was to evaluate the effects of areca nut extracts on phagocytic activity by neutrophils isolated from gi...

In diesem Beitrag werden zwei Softwarewerkzeuge zur Datenbank-Analyse und -Normalisierung vorgestellt. TANE-java dient zur Extraktion von funktionalen Abhängigkeiten aus relationalen Datenbanken. DBNormalizer dient zur Normalisierung relationaler Datenbanken auf Basis funktionaler Abhängigkeiten. Ergebnis ist ein ausführbares SQL-Skript zur Schemamodifikation und Datenmigration. Die Werkzeuge k...

Flotasyon işlemlerinde tane boyutu ve morfolojisi gibi tanelerin fiziksel özellikleri, hem tane-tane de tane-kabarcık etkileşimlerinde önemli bir rol oynar bu da onları flotasyon işlemlerinin değerlendirilmesinde çok kılmaktadır. Bu çalışmada, farklı sürelerde pürüzlendirilen galen tanelerinin pürüzlülük süresine bağlı olarak elde edilen morfolojik özelliklerinin verimi topaklanma özelliklerine...
