This paper presents an evaluation of the performance impact of two generic group communication APIs, namely Hedera and jGCS, over three well-known group communication systems, namely JGroups, Spread and Appia. The evaluation compared the performance of different configurations of the three group communication systems in a local clustered environment, under different message and cluster sizes, b...

Anemone flaccida Fr. Schmidt, a family of ancient hopanoids, have been used as traditional Asian herbs for the treatments of inflammation and convulsant diseases. Previous study on HeLa cells suggested that triterpenoid saponins from Anemone flaccida Fr. Schmidt may have potential antitumor effect due to their apoptotic activities.

A high-performance liquid chromatographic (HPLC) method and a cyclodextrin-modified micellar electrokinetic chromatographic (CD-MEKC) method were developed to separate and determine oleanolic acid (OA) and ursolic acid (UA) in Prunella vulgaris. HPLC separations were carried out on a Hedera ODS C18 column with methanol -H2Oacetic acid (85:15:0.3, v/v/v) as mobile phase at a flow-rate of 0.8 ml ...
