Cloud computing is an emerging computing paradigm that offers the concept of time shared remote services with attractive technological and financial advantages. The infrastructure uses new technology and services which have not been fully evaluated with respect to security.
A few of the concerns include data security, expectations, trust, regulations and performance issues.
Cloud computing environments are multi-domain in which each domain can use different security, privacy and trust requirements and potentially employ various mechanisms, interfaces and semantics. The domain may represent individually enabled services or other infrastructural or application components. Service Oriented Architecture facilitates such multi domain formation through service composition and orchestration.
As the shape of the cloud computing is emerging and rapidly developing conceptually and in reality, the issues such as contractual, service quality, interoperability, security and privacy issues pose serious challenges. In this paper an attempt is made to identify the challenges and suggest technological solutions to mitigate these challenges and facilitate ubiquitous adoption of this technology.

The status of reefs in Palk Bay and the Gulf of Mannar was studied during April–May 2016 following a bleach alert, as the sea surface temperature recorded a sudden increase from 30.5°C to 34.0°C in Gulf of Mannar. About 71.48% ± 8.9% of the corals in Palk Bay and 46.04% ± 3.78% in Thoothukkudi group of Islands in Gulf of Mannar were found bleached, showing a clearly decreasing trend from north to south, which could be attributed to the corresponding pattern in intensity of SST recorded in the study sites. Observations of bleaching patterns among different life-forms showed 68% of the bleached corals were massive forms. It was observed that 22 out of the 26 massive forms were bleached, while the Acropora corymbose (ACC), digitate (ACD) and encrusting coral (CE) forms were not bleached in any of the study sites in Palk Bay and Gulf of Mannar. The study suggests that the ACC, ACD and CE forms have adapted to thermal stress, subsequent to the earlier mass bleaching events. The study highlights the need for understanding the molecular mechanism of the association between corals and the symbiotic algae, for further understanding on coral bleaching in Indian waters.Keywords

Sea anemones are brightly coloured, classified under the phylum Cnidaria, inhabit coastal waters throughout the world, but are particularly abundant in tropical oceans. They are distributed in intertidal to deep oceans and live attached with rocks, sea floor, shells and some forms burrow in the mud or sand. They are radial symmetric with columnar body have a single body opening, mouth which is surrounded by tentacles. However, body shape of the sea anemones is often related to the habitat in which they live. Sea anemones are solitary polyps and are considerably larger and heavier than the polyps of hydrozoans (Barnes, 1982). There are over 1000 species of sea anemones reported worldwide.Full Text

The technology of E-Metering (Electronic Metering) has gone through rapid technological advancements and there is increased demand for a reliable and efficient Automatic Meter Reading (AMR) system. This paper presents the design of a simple low cost wireless GSM energy meter and its associated web interface, for automating billing and managing the collected data globally. The proposed system replaces traditional meter reading methods and enables remote access of existing energy meter by the energy provider. Also they can monitor the meter readings regularly without the person visiting each house. A GSM based wireless communication module is integrated with electronic energy meter of each entity to have remote access over the usage of electricity. A PC with a GSM receiver at the other end, which contains the database acts as the billing point. Live meter reading from the GSM enabled energy meter is sent back to this billing point periodically and these details are updated in a central database. A new interactive, user friendly graphical user interface is developed using Microsoft visual studio .NET framework.
