Application of a three-dimensional hyperbolic location system to the false killer whale (Pseudorca crassidens) depredation issue
Depredation by false killer whale (Pseudorca crassidens) is a serious problem for pelagic longline fishing in the Coral Sea. These interactions have raised substantial ecological, economic and social concerns. McPherson et al. proposed post-processing of passive acoustic recordings to analyse general odontocete acoustic behaviour and assess the effectiveness of systems being developed to reduce ...

The common belief that the age of a pipe determines its condition is rarely correct – in many cases, a newer main can be in worse condition than one twice or three times as old. Instead, operational, environmental and installation factors ...

Mancomunidad de la Comarca de Pamplona (MCP) Identifies 4 Leaks Using Inline Leak Detection
Around the world, leaking water pipelines represent a major resource and financial loss for utilities. It is estimated that in some places, Non-Revenue Water exceeds 50 percent. In terms of financial losses, the World Bank estimates that NRW costs utilities worldwide about US$14 billion annually. By reducing these losses by half in areas with the highest NRW, it is estimated that US$2.9 billion ...
