This paper presents a Particle Swarm Optimization with Improved Inertia Wight (PSO-IIW) for Combined Heat and Power Economic Dispatch (CHPED) problem. The proposed PSO-IIW technique, which is a population based global search and optimization technique, has been developed to solve the CHPED problem. The CHPED problem is formulated as an optimization problem which is solved by the PSO-IIW techniq...

Ceratophysella comosa sp. nov. was collected from ascomata of Ciborinia canielliae in Japan and the morphological and molecular characteristics of the species are described here. The species has 3 + 3 cephalic spines as in Ceratophysella loricata and Ceratophysella pilosa, but a plurichaetosis intermediate between C. loricata (absent) and C. pilosa (strong). The new species can be distinguished...

Some polyacetylenes from the plant Bidens pilosa have been reported to treat diabetes. In this study, we report that the cytopiloyne from B. pilosa, which is structurally different from the above-mentioned polyacetylenes and inhibits CD4(+) T cell proliferation, effectively prevents the development of diabetes in nonobese diabetic mice as evidenced by a normal level of blood glucose and insulin...

A single brachiosaurid sauropod cervical vertebra from the Wessex Formation (Barremian, Early Cretaceous) of the Isle of Wight is remarkable for its size. With a partial centrum length (i.e., excluding evidence of the anterior condyle) of 745 mm it represents the largest sauropod cervical reported from Europe and is close in size to cervical vertebrae of the giant brachiosaurid Brachiosaurus br...

The present study was aimed at identification, isolation and quantification of marker compound Lupeol in Derris heyneana (Wight and Arn) Benth. by using HPTLC. A simple and sensitive High-Performance Thin-Layer Chromatographic (HPTLC) method validation was carried out as per the ICH guidelines for the identification and quantification of biomarker lupeol in root, stem and leaves of Derris heyne...

The genus, Salacia belongs to the family, Celastraceae and is distributed across the world. Roots and stems of Salacia are used mainly as antidiabetic agents in traditional system of medicine such as Ayurveda and Unani. The roots are either chewed directly or taken in dried powdered form or as decoction. Apart from antidiabetic activity, several species of the genus Salacia are known to possess...

Brachylepis nervosa, Wight and Arnot, belongs to the family asclepiadaceae is indigenous to ills of the Nilgiris and distribution of which is restricted to Wellington and kothagiri. The present work summarises preliminary phytochemical characters of this plant.
