Generally the mobile nodes are battery operated which make energy a scarce resource in MANETs. Efficient utilization of the energy is one of the most crucial issues in MANETs. Energy needs to be optimally utilized so that the nodes can perform their functionality satisfactorily. A node in MANET is a router as well, it could be difficult for a mobile node to(More)
A novel approach was applied to synthesize silver nanoparticles using starch under sonication. Colloidal silver nanoparticles solution exhibited an increase of absorption from 420 to 440 nm with increase starch quantity. Transmission electron microscopy followed by selected area electron diffraction pattern analysis indicated the formation of spherical,(More)
The aim of present study was to investigate the phytochemical screening and to compare the antimicrobial activity of oils of Clove bud and Cardamom. Clove bud was successively extracted by steam distillation and isolated with Dichloromethane. The phytochemical analysis revealed the presence of alkaloids, glycoside, steroids, carbohydrates, terpenoids,(More)
In mobile ad hoc networks, the movement of the mobile nodes is one of the important characteristics because it can affect the performance of the routing protocol. The mobility pattern directly influences when communication links between nodes are established or broken, which is associated with the network topology. In this paper, the impact of the different(More)
The objective of this study was to design and develop o/w microemulsion for transdermal delivery of poorly water soluble acyclovir by aqueous titration method. Oleic acid: castor oil (3:1), tween 80, and ethanol were selected as oily phase, surfactant and cosurfactant respectively. The Pseudoternary phase diagrams were constructed by aqueous titration(More)
Vehicular Ad Hoc Networks (VANETs) are a new communication paradigm that enables the communication between vehicles moving at high speeds on the roads. This has opened doors to develop several new applications like traffic engineering, traffic management, dissemination of emergency information to avoid hazardous situations and other user applications.(More)
Superficial mycoses caused by dermatophytic fungi such as Trichophyton rubrum represent the most common type of worldwide human infection affecting various keratinized tissues in our body such as the skin, hair, and nails, etc. The dermatophytic infection is a significant public health threat due to its persistent nature and high recurrence rates, and thus(More)
Microorganisms have provided a bounty of bioactive secondary metabolites with very exciting biological activities such as antibacterial, antifungal antiviral, and anticancer, etc. The present study aims at the optimization of culture conditions for improved antimicrobial production of Paenibacillus elgii obtained from Wayanad forest of Western Ghats region(More)
A Pseudomonas aeruginosa strain, RRLJ 04, and a Bacillus cereus strain, BS 03, were tested both individually and in combination with a Rhizobium strain, RH 2, for their ability to enhance plant growth and nodulation in pigeon pea (Cajanus cajan L.) under gnotobiotic, greenhouse and field conditions. Both of the rhizobacterial strains exhibited a positive(More)
