On the topic of tipping points, we crossed the Rubicon in 2007 at about 0.76 C warming. At this point, according to David Spratt’s excellentSeptember 2013 report, “Is Climate Already Dangerous?”, not only had Arctic sea-ice passed its tipping point, but the Greenland Ice Sheet was not...
In cases where there is more than one combined engine/SCR system with the same highest NOX emission value given to two decimal places (cycle value in g/kWh) within an engine family or an engine group, the parent engine is the system with the highest raw NOX value emitted from the engine...
about by, for example, new forest management and agricultural practices. Nitrogen cycle: The total amount of nitrogen made available to organisms by human activities increased nine-fold between 1890 and 1990, especially since 1950 because of the use of synthetic fertilizers. Human activities are now...
These include : the installation of flue gas desulphurisation equipment at the largest power station, Drax; investment in special burners to reduce nitrogen oxide emissions; installing of equipment to reduce dust emissions at the largest stations; promotion of energy efficiency encouraging the ...
such as Three Gorges Dam. Actions relevant to such things as climate change and tropical deforestation affect the global hydrologic cycle. Public policy must be based on sustainable water practices derived from sound science that informs about water use affects on groundwater, ecosystems, and endanger...

Even as it reaches the sea, where it once spread through a bifurcating, branching network of waterways, the engineers have sent it through a few narrow chutes, hemmed by hardened embankments and jetties and kept open by dredges, in an expensive cycle of futility. Most of its bounty of sed...

Aside from a presumed greater compliance, IER regimens that provide 2496 kJ and 50 g protein on restricted days will help maintain nitrogen balance and muscle mass, which may not be achieved with periods of total fasting (88). IER will evoke a smaller flux in FFAs and ketones than IF (63...
