Soil and root samples of tomato were collected from root knot nematode-infested fields of fifteen different localities of Malakand and Swat (NWFP) Pakistan in 2006-07 and Trichoderma harzianum was isolated from these samples. These isolates were tested against Meloidogyne javanica (Treub) Chitwood in the in vitro. Isolates Th1 and Th9, collected from Jabban and Shamozai were more aggressive tha...

in future high-speed self-routing photonic networks based on all-optical time division multiplexing (otdm) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. in this paper we propose a self-routing otdm node structure composed of an all-optical router and demultiplex...

we give a new proof of the well known wedderburn's little theorem (1905) that a finite‎ ‎division ring is commutative‎. ‎we apply the concept of frobenius kernel in frobenius representation theorem in finite group‎ ‎theory to build a proof‎.

With the emergence of mobile ad-hoc networks, more users desire connectivity regardless of geographic location. MANETs are a promising technology in terms of the applications in the military, emergency situations, and general daily life activities. Various protocols have been developed to handle the routing information in such networks. However, most protocols are vulnerable to various threats....
