Previous work from this laboratory had demonstrated the presence of endogenous morphine, strychnine and nicotine in the mammalian brain and human serum samples. Morphine is synthesised from tyrosine and strychnine and nicotine from tryptophan. This study examines the role of strychnine, nicotine and morphine in neuropsychiatric disorders. The blood levels(More)
Active networks provide a programmable user-network interface that supports dynamic modification of the network's behavior. Network nodes, in addition to forwarding packets, perform customized computation on the messages flowing through them. Resources in an active network mainly comprise of CPU and bandwidth. An efficient allocation is required for the(More)
Two substances which are products of the isoprenoid pathway, can participate in lipid peroxidation. One is digoxin, which by inhibiting membrane Na(+)-K+ ATPase, causes increase in intracellular Ca2+ and depletion of intracellular Mg2+, both effects contributing to increase in lipid peroxidation. Ubiquinone, another products of the pathway is a powerful(More)
This paper proposes a mutual authentication technique for use in the wireless mobile network. Authentication of mobile subscribers is a challenging issue due to increasing security threats as it acts as the first defence against attackers. We come up with a novel authentication mechanism, called Group Registration, which reduces the huge bandwidth(More)
Cloud computing is nowadays replacing the office based computing. As cloud computing becomes more widespread, the allocation of network and computing resources will be an issue. While data center energy use has received much attention recently, there has been less attention paid to the resource (CPU processing time and bandwidth) estimation in the cloud(More)
Active networks provide a programmable user-network interface that supports dynamic modification of the networkpsilas behavior. Network nodes, in addition to forwarding packets, perform customized computation on the messages flowing through them. Individual packets carry executable code, or references to executable code. Resources in an active network(More)
The aim of this paper is to design a transceiver that achieves a data rate of minimum 4Gbps equivalent to the 4G standard of IEEE. Multiple Carrier Code Division Multiple Access (MC-CDMA) is the combination of code division multiple access (CDMA) and orthogonal Frequency Division Multiplexing (OFDM), therefore the advantages of both schemes can be achieved.(More)
