The taxation of drivers and the choice of car fuel type [PDF]
Energy Economics, 1999 In this paper the choice of the car fuel type is studied. In the Dutch situation three types are important: gasoline, diesel and LPG, with 80% of the cars using gasoline. Incentives for using diesel or LPG are provided by the tax system that implies higher fixed cost, but lower variable cost for users of these fuel types. We start by studying fuel type

The effects of fuel type on control rod reactivity of pebble-bed reactor
Nukleonika, 2019 As a crucial core physics parameter, the control rod reactivity has to be predicted for the control and safety of the reactor. This paper studies the control rod reactivity calculation of the pebble-bed reactor with three scenarios of UO2, (Th,U)O2, and ...

Species composition and fire: non-additive mixture effects on ground fuel flammability
Frontiers in Plant Science, 2012 Biodiversity effects on many aspects of ecosystem function have been well documented. However, fire is an exception: fire experiments have mainly included single species, bulk litter, or vegetation, and, as such, the role of biodiversity as a ...
