The essential oils obtained by hydrodistillation from the fresh leaf and stem of Piper porphyrophyllum N.E. Br. were analyzed by GC and GC/MS. Thirty four constituents were identified in the leaf oil, while thirty eight constituents were identified in the stems oil. The most abundant components in the leaf oil included bicyclogermacrene (14.7 %), α-copaene(More)
Chemical composition, antioxidant and antimicrobial activities of the fresh leaves and stems oils of Piper caninum were investigated. A total of forty eight constituents were identified in the leaves (77.9%) and stems (87.0%) oil which were characterized by high proportions of phenylpropanoid, safrole with 17.1% for leaves and 25.5% for stems oil.(More)
The workload of the NSF supercomputer center at the University of Illinois is decomposed into its major constituent programs, and performance characteristics of those programs are described in detail. The resulting data is compared with similar data obtained from standard benchmarks showing that applications level programs are clearly distinct from kernel(More)
A solid acid membranes based on poly (vinyl alcohol) (PVA), sodium bromide (NaBr) and phosphoric acid (H3PO4) were prepared by a solution casting method. The morphological, IR, electrical and optical properties of the (PVA)0.7(NaBr)0.3(H3PO4) x M solid acid membranes where x = 0.00, 0.85, 1.7, 3.4, 5.1 M were investigated. The variation of film morphology(More)

— Mobile agents represent a promising technology for the development of distributed applications. Most of these applications consist of multiple agents that need to interact with one another at various stages of their execution for exchanging information and synchronization. The coordination and cooperation of multiple agents require that the traditional(More)
