Bacteriophages or phages are the viruses that infect bacteria. Phages like all viruses are made up of a nucleic acid core which is surrounded by a protein coat. The majority of phages are known to contain DNA but some contain RNA also. In this study, four salmonella phages were isolated and were subjected to molecular characterization. All the four Salmonella phages were found to contain DNA as...

Host-side flash storage opens up an exciting avenue for accelerating Virtual Machine (VM) writes in virtualized datacenters. The key challenge with implementing such an acceleration layer is to do so without breaking live VM migration which is essential for providing distributed resource management and high availability. High availability also powers-on VMs on new host when the previous host cr...

Cholesterol is a multifunctional lipid that plays important metabolic and structural roles in the eukaryotic cell. Despite having diverse lifestyles, the obligate intracellular bacterial pathogens Chlamydia, Coxiella, Anaplasma, Ehrlichia, and Rickettsia all target cholesterol during host cell colonization as a potential source of membrane, as well as a means to manipulate host cell signaling a...

In the current era of cloud computing, data stored in the cloud is being generated at a tremendous speed, and thus the cloud storage system has become one of the key components in cloud computing. By storing a substantial amount of data in commodity disks inside the data center that hosts the cloud, the cloud storage system must consider one question very carefully: how do we store data reliabl...

Plant parasitic nematodes (PPN) are known to survive periods of desiccation, an ability that increases the risk of them surviving unintentional transport between countries. To investigate nematode survival in soil subject to prolonged storage, soil collected from a native forest and an organic orchard was stored separately in cupboards at ambient temperature for 36 months. Subsamples were taken...

Eggs of Ephestia kuehniella (Zeller), Cadra cautella (Walker) and Plodia interpunctella (Hübner) are host parasitoid Trichogramma pintoi (Hymenoptera: Trichogrammatidae) which is used in biological control pests. In this study, the species egg age preferences were determined parasitization performance adult female T. pinto. For preference, 1, 2, 3 4 days old eggs from three different hosts give...

this guide to the identification of iranian freshwater snails has been prepared with aim of helping individuals involved in field work, but who have had no specialized training in taxonomy to differentiate snail specimens which they collect to certain groups by means of simple identification key. the guide pays special attention to the principal snail groups which transmit human schistosomiasis...

Many applications today are highly data intensive and have stringent performance requirements. In order to meet the performance demands of these applications, we need to optimize both the processing and I/O subsystems. One promising approach to optimize performance is to use “Active Storage” systems, where we use disk drive controllers and storage array controllers as offload processors for the...

Due to the unending increase in scalability and performance demands, the network attached storage paradigm is being adopted as the solution for large storage systems. This new shift seeks to decentralize storage elements over a network where the idea is to transfer data directly between the storage disks and client machines thereby completely bypassing the fileserver machine bottleneck. The new...

The network bottleneck incurred by big data process and transfer has increasingly become a severe problem in today's data center and cloud storage. Exploring and exploiting the advantages of both the scalable object storage architecture and intelligent active storage technology are one of the ways to address this challenge. In this talk, we present the design and performance evaluation of Oasis...
