in order to adapt lasota strain of newcastle disease virus (ndv) on chick embryo fibroblast (cef) cells, 0.1 ml from lasota vaccine produced in razi vaccine and serum research institute inoculated to the cef cells and was passaged five times in the cef grown in eagle’s minimum essential medium (mem). first to third passages were blind but in fourth passage cytopathic effect of virus was observe...

We present a transaction processing scheme for structured overlay networks and use it to develop a distributed Wiki application that is based on a relational data model. The Wiki supports rich metadata and additional indexes for navigation purposes. Ensuring consistency and durability requires handling of node failures. We mask such failures by providing high availability of nodes by constructi...

From the idea of using an array of isolated wireless ports called Infostations, we consider the use of existing cellular infrastructure as the location for these Infostations. The coverage area of Infostations, though, will be smaller than the cell area. We determine the worst-case SIR as a function of the coverage-radius-to-cell-radius ratio and the frequency-reuse cluster size. For specific m...

We introduce an architecture for “Intradomain Overlays”, where a subset of routers within a domain is augmented with a dedicated host. These strategically placed hosts form an overlay network, and we describe a number of applications for such overlays. These applications include efficient network monitoring, policyand load-based packet re-routing, and network resource accounting. In this paper,...

Peer-to-peer (P2P) applications have become countless since they were initially proposed about ten years ago. They became popular among the general public when being used as a platform for file sharing. However, their robustness and scalability sparked interest from industry and research. Today these concepts drive some of the main businesses as back ends or migrate intensive workload away from...

Structured overlay networks form a major class of peer-to-peer systems, which are touted for their abilities to scale, tolerate failures, and self-manage. Any long lived Internet-scale distributed system is destined to face network partitions. Although the problem of network partitions and mergers is highly related to fault-tolerance and self-management in large-scale systems, it has hardly bee...

AIM To test a theory of visual stress by investigating the inter-relationships between (1) the threshold contrast/saturation at which individuals first report discomfort when viewing colored gratings of progressively increasing contrast and decreasing saturation; (2) the choice of a colored overlay for reading; (3) any increase in reading speed when the overlay is used. METHOD Ninety-five you...

ABSTRACT We present the results from studying 140 radio sources in GLEAM (GaLactic and Extragalactic All-sky MWA [Murchison Widefield Array]) 4-Jy (G4Jy) Sample. These were followed-up with MeerKAT to assess their morphology enable host-galaxy identification, as existing images of 25 45-arcsec resolution do not provide sufficient information. refer these MeerKAT-2019 subset. The aim is identify...

In vitro cultivation of Leishmania parasites plays an important role in diagnosis and treatment leishmaniasis vaccine drug development studies. There is no information about the effects urine within culture on infectivity parasites. In this study we used two media with different overlays to enhance growth rates donovani.
