Biochemical responses of cucumber to Tetranychus urticae Koch (Acari: Tetranychidae) mediated biotic stress
The effect of two spotted spider mite (Tetranychus urticae Koch) feeding on leaf level physiological characteristics of cucumber (Cucumis sativus Linnaeus) was investigated. Young cucumber plants were artificially infested with different densities of T. urticae (5, 10, 15 and 20 mites/ grown up leaf) while uninfested plants acted as control. Post infestation, the plants differed in their support to mite density in accordance with initial infestation density and observation period. Highly significant negative correlation of -0.92, -0.93, -0.95 and -0.92 for total chlorophyll, chlorophyll a, chlorophyll b and carotenoids, respectively, at the highest infestation level) was recorded between mite density and photosynthetic pigments in infested leaves as compared to uninfested ones. There was a significant decrease (P= 0.05) in the level of (a progressive decline from 2.82, 0.36 and 2.17% dry weight in control to the maximum of 2.09, 0.26 and 1.87% dry weight for N, P and K, respectively, at highest infestation level) in the infested leaves in response to mite infestation. Interaction between initial infestation level and observation period also suggested a significant impact of T. urticae infestation on the leaf phytochemicals of cucumber (P= 0.05)
Survey on Security Issues in Cloud Computing Environment
ABSTRACT: Cloud has introduced a new concept of provision of on-demand resource to services on internet. Cloud provides an attractive model while allowing the service providers to save cost. It allows users to free themselves of tasks of resource management i.e. most efficient use of resources. It also allows centralization of information and resources so that the users can access them from anywhere using the internet. Generally the resources used to provide services belong to a third party. As the users don't have to invest capital in such resources it decreases costs. Even though cloud model is lucrative, users have been hesitant in adopting it, the major reason being security concern regarding their private data. In this paper we discuss about various security concerns in cloud environment

Green Herring Syndrome: Bacterial Infection in Patients With Mucormycosis Cavitary Lung Disease
Mucormycosis is a life-threatening fungal disease in patients with hematological malignancies. The diagnosis of pulmonary mucormycosis is particularly challenging. We describe 3 mucormycosis cases with an uncommon presentation in patients whose cavitary lung disease was attributed to well documented bacterial infection, although evolution and reassessment established mucormycosis as the underlying disease
