  • Wildland fires are natural calamities that bring enormous environmental and economic damage worldwide and some of them cause human death. Achieving effective fire fighting is associated with the possibilities of predicting the characteristics of fire behaviour.

The first two are characteristic of the paper industry. The levy rates were reassessed in 1989 and increased in 1992. Wang et al.

  • Today, the budget structures of the two countries show many formal similarities, but the de facto operations of central and sub-national bureaucracies diverge. Most Western discussions of fiscal efficiency start from the assumption that there is a separate, tax-based fiscal system in place. However, neither Russia nor China has succeeded fully in establishing an effective, tax-based system for provision of local infrastructure, pensions, and a social safety net.
