It is shown that spillovers can enhance private returns to innovation if they feed back into the dynamic research of the original inventor (Internalized spillovers), but will always reduce private returns, if the original inventor does not benefit from the advancements other inventors build into the “spilled” knowledge (Externalized spillovers). I empirically identify unique patterns of knowled...

As the oil spill models are usually based on the sea surface and few researches are for submarine oil spill nowadays, the simulation for submarine pipeline oil spill is discussed by FLUENT to forecast the trajectory of oil. The coupling of pressure and velocity under unsteady-state condition is solved by pressure implicit with splitting of operator’s algorithm and the boundary condition of nonl...

Scientists Investigate Burned Gulf Spill Emissions Much of the oil spilled during the BP Deepwater Horizon disaster in the Gulf of Mexico was burned to keep it from reaching the shoreline or harming sea life. NOAA scientists have analyzed the gas and aerosol emissions resulting from the burning of the spilled oil and found that over a 9-week period more than 1 million pounds of black carbon wer...

The superior oil absorption capacity of recycled polypropylene (PP) fiber and waste tire powder were used to recover spilled engine oil. We used ASTM F726-99 method to evaluate oil adsorbing capability of PP fiber and found it to have a large, rapid oil sorption capacity. However, its lack of elasticity dramatically limited that capacity after repeated use. Tire powder, which absorbs less oil m...
