Objectives: A unique and effective algorithm for location based key generation is devised and implemented which makes use of dynamic key exchange based on the GPS Location. This approach makes the communication more secured and reliable with the avoidance of Wicked WiMax Node attacks. Methods/Statistical Analysis: The dynamic movement of malicious node is deeply analyzed with the probability of identification of sniffing and intrusion in the network makes the overall scenario secured and integrity aware. Findings: The projected approach of identifying the malicious node is effectual making the overall network environment secured with the deep of wicked node attacks. Using this approach, the overall network intrusions can be controlled and avoided from wicked node attacks. Application/Improvements: The recognition and logging the wicked node attempts is making the defense aware anti intrusion network environment against assorted network assaults.Keywords

Objectives: To observe the bio-distribution and change in blood kinetics of iron chelating drug-desferrioxamine covalently bound to high-molecular weight dialdehyde cellulose. Methods/Statistical Analysis: The DAC-DFO conjugate and free desferrioxamine were labeled with radiotracer 99mTc. In vitro studies, to establish quality control parameters, were performed by instant thin layer chromatography followed by intravenous administration of radio complexes to the rabbits. Gamma camera imaging was carried out and bio-distribution parameters of both conjugate and free drug were evaluated and compared. Findings: Both polymers based and free desferrioxamine samples exhibited > 90% radiolabelling efficiency and a high in-vitro stability. There was significant improvement in blood circulation time after covalent binding of DFO to DAC (at 1500 min) compared to free DFO (at 900 min) After a single injection of 99mTc-DAC-DFO, the highest distribution was observed in the liver at 19.5 minutes with lower uptake in kidneys and urinary bladder till 30min. On the other hand, the highest distribution of free DFO in liver was highest at only 1 minute post-administration. Application/Improvements: The bioavailability of desferrioxamine was found to be enhanced upto several folds after conjugation to oxidized cellulose.Keywords
