7 RATIONALE: Bulk and position-specific stable isotope characterization of nitrous oxide 8 represents one of the most powerful tools for identifying its environmental sources and sinks.

A k-disjoint path cover (k-DPC for short) of a graph is a set of k internally vertex-disjoint paths from given sources to sinks that collectively cover every vertex in the graph. In this paper, we establish a necessary and sufficient condition for the cube of a connected graph to have a 3-DPC joining a single source to three sinks. We also show that the cube of a connected graph always has a 3-...

Disseminating data from sources to sinks is a very important application in sensor networks. This paper presents a new data dissemination scheme which uses the concept of the Fermat Point to construct a dissemination tree from one source (the root) to multiple sinks (the leaves). By sending data along the dissemination tree, the new scheme can conserve transmission energy, avoid collision and a...

Designing tools that aim at a sustainable management of waste and organic residues requires a good knowledge of the available sources and their use potential. Resulting choices should consider localisation of these sources and of the sinks capable of absorbing them. Absorptive capacities of such sinks like crops may vary in space and time as a function of their nutritional requirements. Positio...

The atmospheric budget of methyl bromide (CH(3)Br), an ozone-depleting gas, is highly uncertain, because it has complex sources and sinks. Although oceans, biomass burning, and industrial production are identified as the major sources, the fraction of CH(3)Br that is contributed by each source is not well known. A mass-balance approach that exploits differences in the carbon isotopic signature ...

This paper presents the feasibility study of CO2 sequestration from the sources to the sinks in the prospective of Italian Industries. CO2 produced at these sources captured, compressed to supercritical pressures, transported via pipelines and stored in underground geologic formations such as depleted oil and natural gas reservoirs, un-minable coal seams and deep saline aquifers. In this work, ...
