  • One concern about the voluntary offset market as it continues to grow is the possibility that suppliers may sell the same reductions to multiple buyers, because there is no central authority to track their transactions.

  • Although a steadily increasing number of protein±ligand docking experiments have been performed successfully, there are only few studies concerning protein±sugar inter-actions. In this study, we investigate the interaction of wheat germ agglutinin (WGA) withN-acetylglucosamine and a number of its derivatives and predict the binding free ener-gies using ¯exible docking techniques.

  • Chapter 10 - Arbitrage pricing theory and multifactor models of risk and return. We begin by showing how the decomposition of risk into market versus firm-specific influences that we introduced in earlier cha pters can be extended to deal with the multifaceted nature of systematic risk.
