Plumeria acutifolia Poiret (Apocynaceae) is grown as an ornamental plant in India, Indonesia, Philippines and South Africa. Various species of this plant are used as medicine to cure many diseases and also as antipsychotic, diuretic, or antitumour agent. Some iridoids and triterpenoids obtained from this plant are reported to have algicidal, antibacterial and cytotoxic activity. Some species of Plumeria are also used for the cure of rheumatism, diarrhoea, blennorhea, venereal disease and leprosy. This study investigates the taxol production by Colletotrichum gloeosporioides, an endophytic fungus of Plumeria acutifolia. The presence of Taxol was confirmed through TLC, UV and IR spectroscopic methods. The amount of taxol was quantified through HPLC analysis. This is the first report that a coelomyceteous fungus producing taxol from this plant.Keywords

In multihop wireless networks, when a mobile node needs to communicate with a remote destination, it relies on the other nodes to relay the packets. Multihop packet transmission can extend the network coverage area using limited power and improve area spectral efficiency. Some nodes may break routes because they do not have sufficient energy to relay the source nodes packets and keep the routes connected. Randomly selecting the intermediate nodes for sending data degrade the routes stability. We propose TEAR (Trust-based and Energy Aware Routing) combines payment and trust systems. The payment system rewards the nodes that relay others packets and charges those that send packets. The trust system evaluates the nodes competence and reliability in relaying packets in terms of multi dimensional trust values. TEAR can stimulate the nodes not only to relay packets, but also to maintain route stability and report correct battery energy capability.

The overture of the work is principally focused on Error Corrections Code (ECC) for the Parallel Transforms. And this error corrections code doesn’t handle the more designing area of the actual design. To detect and correct errors with the help of algorithmic properties such as Algorithm Based Fault Tolerance (ABFT) techniques makes the avoidance of soft errors. By using algorithm based fault tolerance technique, the communication systems and signal processing systems, can be implemented with fast Fourier transforms (FFT) which are considered to be the basic building blocks of all signal processing systems. The proposed method can able detect multiple errors and multiple error corrections also possible upon best-case analysis.Keywords

Since the beginning of screening of Phyto-chemicals, the use of natural products in medicinal application has reduced. Medicinal plants, since times immemorial, have been used for curing of many diseases as a source of medicine. The presence of study focuses on extraction of Psidium guajava and Punica granatum plant leaves for treatment against diarrhoeal infection. Different parts of the plants are considered to have potential medicinal properties and are used in different system of medicine. Two plant species Psidium guajava and Punica granatum were screened for bio-active compound and detection of anti-bacterial activity against isolated pathogenic strains.Keywords
