Appendix 279 The technological and economic potential to reduce greenhouse gas (GHG) emissions is large enough to hold annual global greenhouse gas emissions to levels close to or even below those of 2000 by 2010 and even lower by 2020. Realization of these reductions requires combined actions in all sectors of the economy including adoption of(More)
Public key encryption was first introduced by Diffie and Hellman in 1976. Since then, the Diffie-Hellman key exchange protocol has been used in developing public key systems such as Rivest-Shamir-Adleman and elliptic curve cryptography. Chaotic functions, so far, have been used for symmetric cryptography only. In this Letter we propose, for the first time,(More)
Enhanced cyclooxygenase-mediated prostaglandin (PG) turnover occurring during sacrifice and biochemical processing of tissues also generates malondialdehyde (MDA), a product of lipid peroxidation (LPO). Studies reporting on LPO estimated by thiobarbituric acid reactive substances (TBARS) have failed to consider such artefactual increases. This study reports(More)
We have tested the hypothesis that chronic exposure to the principal constituents of the aqueous fraction of coal tar extracts can lead to the in vivo formation of substances which may produce neurological damage as the result of free radical generation and lipid peroxidation, these may be involved in the etiology of some neurological disorders.
