Performance Enhancement of MANET based on Cross-layered Reconfigurable Hierarchical Routing Protocol
High speed data communication is the demanding factor in both commercial and defence applications. Several algorithms are proposed to support the high-speed data exchange while ensuring the quality, performance and reliability. However, there is still a gap, citing various compatibility issues with variety of transceiver technologies. This paper proposes a novel algorithm for enhancing the performance of mobile ad-hoc networks using Free-Space Optics (FSO). The FSO has the natural ability to the interference while capable of large bandwidth and excellent compatibility. Low power and adaptability are the features with which it has contributed to the latest technologies like storage area network, wireless area network etc. The proposed work uses optical spheres with a multi-transceiver system and a cross-layered reconfigurable routing mechanism. Parameters such as delay, residual energy, throughput, and drop are verified for the Crosslayered Reconfigurable Hierarchical Routing Optical Sphere (CRHROS) protocol for varying numbers of optical transceivers. The proposed work also compares the performance of two traffic sources, Constant Bit Rate (CBR) and Variable Bit Rate (VBR), for the proposed algorithm
A novel TPR-BEN domain interaction mediates PICH-BEND3 association
PICH is a DNA translocase required for the maintenance of chromosome stability in human cells. Recent data indicate that PICH co-operates with topoisomerase IIα to suppress pathological chromosome missegregation through promoting the resolution of ultra-fine anaphase bridges (UFBs). Here, we identify the BEN domain-containing protein 3 (BEND3) as an interaction partner of PICH in human cells in mitosis. We have purified full length PICH and BEND3 and shown that they exhibit a functional biochemical interaction in vitro. We demonstrate that the PICH-BEND3 interaction occurs via a novel interface between a TPR domain in PICH and a BEN domain in BEND3, and have determined the crystal structure of this TPR-BEN complex at 2.2 Å resolution. Based on the structure, we identified amino acids important for the TPR-BEN domain interaction, and for the functional interaction of the full-length proteins. Our data reveal a proposed new function for BEND3 in association with PICH, and the first example of a specific protein-protein interaction mediated by a BEN domain

Photo induced synthesis of methyl derivative of cryptosanguinolentine
692-696A simpler method to synthesize methyl derivative of an alkaloid cryprosanguinolentine is described. 4-Hydroxy-2-methylquinoline is iodized using iodine, potassium iodide and aqueous sodium hydroxide and dehydroxyhalogenated with phosphorous oxychloride. The respective anilinoquinoline is prepared and cyclized by UV irradiation. Upon selective methylation 5,6-dimethyl-5H-indolo[3,2-c]quinoline is produced which is utilized as a DNA intercalating agent

Performance Enhancement of MANET based on Cross-layered Reconfigurable Hierarchical Routing Protocol
322-327High speed data communication is the demanding factor in both commercial and defence applications. Several
algorithms are proposed to support the high-speed data exchange while ensuring the quality, performance and reliability.
However, there is still a gap, citing various compatibility issues with variety of transceiver technologies. This paper
proposes a novel algorithm for enhancing the performance of mobile ad-hoc networks using Free-Space Optics (FSO). The
FSO has the natural ability to the interference while capable of large bandwidth and excellent compatibility. Low power and
adaptability are the features with which it has contributed to the latest technologies like storage area network, wireless area
network etc. The proposed work uses optical spheres with a multi-transceiver system and a cross-layered reconfigurable
routing mechanism. Parameters such as delay, residual energy, throughput, and drop are verified for the Crosslayered
Reconfigurable Hierarchical Routing Optical Sphere (CRHROS) protocol for varying numbers of optical transceivers. The
