A system and method for remediation of polluted sites, implementing a combination of chemical and biological breakdown modes on the contaminating compounds. The system includes at least one reactor for production in situ of reagents required for the breakdown modes. The reactor includes at least ...
For one system, traction energy is separated into propulsion and dead-heading contributions, with the result that a large fraction is used to keep the cars "hot". For the same system, station lighting accounts for most of the energy use by the stations; for another, heating can double ...

The well-known investigations of vortex breakdown are supplemented with an exact analytic representation of this phenomenon on the basis of the complete Navier-Stokes equations for the case of a potential swirl of the input flow about the axis of symmetry. DOI: 10.1007/BF02282463 被引量: 2 ...
the arrival of Westerners and the conversion of land into pineapple and sugar plantations in the 19th century. When those closed in the late 1900s, the fallow lands became covered in invasive grasses. That and prolonged drought created a “volatile fue...
The theory of critical distances (TCD) is the name which I have given to a group of theories used for predicting the effects of notches and other stress concentration features. The basic meth 这个项目的目标将介绍重要距离的理论,学报的这个特别问题是献身的。 重要距离TCD的理论 () 是我给了为...
But inflation for "services" — which might include anything from haircuts to hotel stays — has proven a bit stickier. Labor costs are a big driver. Demand for workers is near historic highs and theunemployment rate is low, helping fuel competition for workers and thereforefast-rising wages....
Some breakdown cover companies simply won’t come out if you run out of fuel, fill up with the wrong fuel, get a flat battery or lose your car keys (GEM Motoring Assisthave limits for roadside assistance in these scenarios but, under ourbreakdown cover policy, we will help). ...
A well-installed ground source heat pump system is capable of providing 3 to 4.5 times the amount of electrical energy it consumes in the form of heat energy for your home. This is possible because ground source heat pumps move heat, rather than burning fuel. As a comparison, the best ...
A blank sample of a stirred sludge without demulsifier system was used for comparison. A screen test was carried to find out the optimum demulsifier system concentration which results in maximum % aqueous phase separation. It was found that the best performance was achieved at demulsifier system ...
