BACKGROUND The homeopathic preparation of Pulsatilla nigricans is used in the treatment of anxiety related disorders. Though in clinical use for many years, the anxiolytic activity of Pulsatilla nigricans (Puls) has not been evaluated experimentally. Hence the present study was conducted in Swiss albino mice to evaluate the anxiolytic activity of Puls and(More)
Cloud computing is an emerging computing paradigm in which resources of the computing infrastructure are provided as services over the Internet. As promising as it is, this paradigm also brings forth many new challenges for data security and access control when users outsource sensitive data for sharing on cloud servers, which are not within the same(More)
Efficient utilization of energy of the network is one of the major issues faced by wireless sensor network, when sensors are placed in a hostile environment. One of the methods to solve this problem is to activate only a few sensors which satisfy the coverage constraints. This can be done by partitioning a set of all sensors into many subsets or sensor(More)
Cloud computing is making it possible to separate the process of building an infrastructure for service provisioning from the business of providing end user services. Today, such infrastructures are normally provided in large data centres and the applications are executed remotely from the users. One reason for this is that cloud computing requires a(More)

With the hasty popularity of cloud computing data possessor are stimulated to move their intricate data from local repository to commercially available open cloud. We need to search and retrieve all the files which are semantically linked to the query in addition to the precise identical file in a secured manner. But for protecting sensitive information(More)
Abstract: In this paper a novel radial stub feeding microstrip bow-tie antenna is designed to operate between C and X band and its performance characterization is presented. This antenna is having simple structure and topology over other stub loaded antennas. In addition the proposed antenna adjusts to the desired frequency easily. Antenna output parameters(More)
