    Recovery and Partial Purification of Bovine ?-Lactalbumin from Whey Using PEG 1000 – Trisdoium Citrate Systems
    (Taylor and Francis Inc. 325 Chestnut St, Suite 800 Philadelphia PA 19106, 2015) Sivakumar, K.; Iyyaswami, R.
    The extraction of ?-Lactalbumin (?-La) and ?-Lactoglobulin (?-Lg) from whey have been carried out in the Aqueous Two Phase System (ATPS) composed of PEG 1000 – tri sodium citrate. The suitable conditions for the simultaneous partitioning of ?-La into the top phase and ?-Lg in bottom phases was identified using the pure ?-La and ?-Lg. Maximum partition coefficient (k) of 16.67 was achieved for ?-La at the system condition of 28% (w/w) PEG 1000-14% (w/w) tri sodium citrate at pH 8 and 40°C, whereas in this condition k of ?-Lg is 0.27. 30% (w/w) whey loaded to this system yielded the maximum recovery of ?-La and ?-Lg. © , Copyright © Taylor & Francis Group, LLC.

    Vulnerability Testing of RESTful APIs Against Application Layer DDoS Attacks
    (Science and Information Organization, 2025) Sivakumar, K.; Santhi Thilagam, P.S.
    In recent years, modern mobile, web applications are shifting from monolithic application to microservice based application because of the issues such as scalability and ease of maintenance.These services are exposed to the clients through Application programming interface (API). APIs are built, integrated and deployed quickly.The very nature of APIs directly interact with backend server, the security is paramount important for CAP. Denial of service attacks are more serious attack which denies service to legitimate request. Rate limiting policies are used to stop the API DoS attacks. But by passing rate limit or flooding attack overload the backend server. Even sophisticated attack using http/2 multiplexing with multiple clients leads severe disruptions of service. This research shows that how sophisticated multi client attack on high workload end point leads to a dos attack. © (2025), (Science and Information Organization). All rights reserved.
