This paper describes the generation of optimal atmospheric measurement networks for determining carbon dioxide fluxes over Australia using inverse methods. A Lagrangian particle dispersion model is used in reverse mode together with a Bayesian inverse modelling framework to calculate the relationship between weekly surface fluxes, comprising contributions from the biosphere and fossil fuel comb...

Studies were carried out on the localization and mapping of gas stations in the urban area of São Carlos city, for an environmental diagnosis related to soil, surface water and underground water contamination resulting from likely leaking in fuel underground storage tanks. Considering that a provision of legal restriction makes it possible that most of public areas are not located in gas statio...

After the establishment of the first quarantine station in the Republic of Ragusa (modern-day Dubrovnik) in 1377, the states and principalities of Italy developed a sophisticated system of defensive quarantine in an attempt to protect themselves from the ravages of plague. Using largely unknown and unseen historical maps, this paper reconstructs the extent and operation of the system used. It i...

R technological advances in the application of hydrogen fuel cells in the transport sector have drawn considerable attention and increased funding from both public and private sources over the past ten years. Th e International Energy Agency estimates that about US$1billion per year is currently being invested in public hydrogen and fuel cell research, development, test vehicles, prototype refu...

Atmospheric carbon dioxide and pollution due to the burning of fossil fuels is increasing. Many scientists attribute global warming to the rising levels of carbon dioxide and other pollutants, some of which also pose risks to health. These can he reduced by the more efficient use of conventional fuels and the development of nonpolluting energy resources. Fuel cells offer a highly efficient and ...

Due to global concerns about environmental sustainability in ground logistics, there has been widespread research into alternative-fuel (alt-fuel) vehicles. Compressed natural gas buses have been successfully deployed on a commercial scale in public transportation. Also, sales for electric cars have been gradually increasing. However, uses of other alt-fuel vehicles are in their early stages be...
