摘要

"Be fearful when others are greedy and be greedy when others are fearful." Thus wrote Warren Buffett in the 2006 annual report of Berkshire Hathaway, his holding company. True to his maxim, in the last week of December Mr Buffett splashed out $4.5 billion for a majority stake in Marmon Holdings, an industrial conglomerate, and €300m ($441m) for a reinsurer owned by ing Group of the Netherlands. But his most intriguing investment, announced on December 28th, was his smallest: $105m to fund Berkshire Hathaway Assurance Corporation (bhac), a start-up that will insure bonds issued by American states, cities and counties to finance schools, roads, hospitals and other public projects.

7. The thermodynamic changes that occur upon mixing five models of formamide and three models of water, including the miscibility of these model combinations itself, is studied by performing Monte Carlo computer simulations using an appropriately chosen thermodynamic cycle and the method of thermodynamic integration. The results show that the mixing of these two components is close to the ideal mixing, as both the energy and entropy of mixing turn out to be rather close to the ideal term in the entire composition range. Concerning the energy of mixing, the OPLS/AA-mod model of formamide behaves in a qualitatively different way than the other models considered. Thus, this model results in negative, while the other ones in positive energy of mixing values in combination with all three water models considered. Experimental data supports this latter behavior. Although the Helmholtz free energy of mixing always turns out to be negative in the entire composition range, the majority of the model combinations tested either show limited miscibility, or, at least, approach the miscibility limit very closely in certain compositions. Concerning both the miscibility and the energy of mixing of these model combinations, we recommend the use of the combination of the CHARMM formamide and TIP4P water models in simulations of water-formamide mixtures.
