Carbon monoxide, ethylene, and propylene were produced in illuminated, cell-free distilled water or natural seawater systems to which dissolved organic matter produced by phytoplankton had been added. Methane and the higher saturated gaseous hydrocarbons were not produced. In the dark, little or no carbon monoxide and no hydrocarbons were produced in the(More)
Trichlorofluoromethane (CCl3F) measurements in the troposphere over the Atlantic in 1971 and over the Pacific in 1972 and 1974 were compared. A rapid increase of CCl3F in the troposphere is evident. The observed increase of CCl3F between 1971 and 1974 is proportional to the increase of industrially produced amounts of CCl3F in the same time period.
Autonomous systems are increasingly seen as enablers for future applications in commercial and military domains. This paper is concerned with platform localization (key element of autonomy) using teams of robots, to support an ongoing research project investigating multi-robot exploration. To our knowledge, the work reported here represents the first(More)
