—In this paper, we develop a trust based security protocol based on a cross-layer approach which attains confidentiality and authentication of packets in both routing and link layers of MANETs. In the first phase of the protocol, we design a trust based packet forwarding scheme for detecting and isolating the malicious nodes using the routing layer(More)
Background. The most common species isolated from primary endodontic infections are black-pigmented bacteria. These species are implicated in apical abscess formation due to their proteolytic activity and are fastidious in nature.

BACKGROUND Abdominal wall defects and hernias are commonly repaired with synthetic or biological materials. Adhesions and recurrences are a common problem. A study was conducted to compare Chitosan coated polypropylene mesh and a polypropylene-polydioxanone composite with oxidized cellulose coating mesh (Proceed™) in repair of abdominal wall defect in a(More)
Environmental exposure of Cr(VI) and Ni(II) due to rapid industrialization causes adverse effects in living tissues. Small quantities of these ions also find their way into tissues when metal alloys are used as implants. Even though considerable research has been done on the effects due to their exposure in animal cells, there are only very few reports on(More)
