We present Schism, a novel workload-aware approach for database partitioning and replication designed to improve scalability of sharednothing distributed databases. Because distributed transactions are expensive in OLTP settings (a fact we demonstrate through a series of experiments), our partitioner attempts to minimize the number of distributed transactions, while producing balanced partition...

The two techniques aqueous two-phase partitioning and expanded bed adsorption that both are suitable for primary protein recovery were studied. Most of the work was focused on partition in aqueous two-phase systems and in particular on the possibility to effect the partition behaviour by fusion of short peptide tags or protein domains to the target protein. The partitioning of fusion proteins b...

Naturally occurring and synthetic estrogens and other molecules from industrial sources strongly contribute to the endocrine disruption of urban wastewater. Because of the presence of these molecules in low but effective concentrations in wastewaters, these endocrine disruptors (EDs) are only partially removed after most wastewater treatments, reflecting the presence of these molecules in river...

The oxygen-evolving photosystem II particles prepared from spinach chloroplasts with brief sonication and Triton X-100 treatment were subjected to butanol/water phase partitioning. Three peripheral proteins of photosystem II having relative molecular masses of 33,000, 24,000, and 18,000 daltons and a part of the manganese atoms associated with photosystem II were partitioned into the aqueous ph...

we report a three-phase bone scintigraphy for the diagnosis of a peripheral bone lesion caused by systemic sarcoidosis. a 32-year-old man with suspected osteomyelitis of the right forefinger underwent three-phase bone scintigraphy with tc-99m hydroxymethylene diphosphonate (hmdp) and single-photon emission computed tomography/computed tomography (spect/ct). the lesion was rich in blood flow acc...
