Eight small, premature infants developed an unusual symptom complex of pulmonary deterioration, thrombocytopenia, liver failure, ascites, and renal failure. Five infants died; the health of the other three infants improved and they were discharged from the hospital. This unusual syndrome occurred after introduction of a new intravenous vitamin E product(More)

The join operation is one of the most frequently used and expensive query processing operations in relational database systems. One method of joining two relations is to use a hash-based join algorithm. Hash-based join algorithms typically have two phases, a partitioning phase and a partition joining phase. We describe how an optimal multi-attribute hash(More)
The sorting or partitioning of relations is very common in relational database systems. Implementations of the join operation include the sort–merge join algorithm, which sorts both relations, and the hash join algorithm, which usually partitions both relations. We describe how clustering records using an optimal multi-attribute hash (MAH) "le, taking the(More)
We apply a more realistic cost model than has often been used in the past to the problems of: (1) implementing join algorithms, (2) implementing relational operations which make use of multi-attribute hash les, and (3) creating better multi-attribute hash le organisations using knowledge of the queries which will be asked. This results in a substantial(More)
BACKGROUND Upper respiratory tract infections are the most common childhood illness. Panax quinquefolius (American ginseng root extract) standardized to contain 80% poly-furanosyl-pyranosyl-saccharides is purported to be effective in adult upper respiratory tract infection but has not been evaluated yet in a pediatric population. OBJECTIVES Our primary(More)
