Peoples Energy Corp., the company that supplies heating gas to homes and businesses in Chicago, Illinois, wants to get tough with people who do not pay their gas bills. Peoples is asking state utility regulators for more power to cut off customers it considers deadbeats. It wants the Illinoi...
where positive\(F\)implies flux from the water to the atmosphere. There are methods to estimate gas fluxes such as the use of floating chambers (Engle and Melack2000; Matthews et al.2003) or by eddy covariance (Anderson et al.1999). However, these methods can be time and/or cost consum...
Previously, the red-shifted emission observed atωτ = 12950 cm−1(CP feature) has been assigned to a resonance in desorbed, free gas-phase Rb2molecules19. Interestingly, the extended information disclosed in our 2DES experiment indicates that this feature rather corresponds to a distinc...
The shape of the corresponding streamlines in the pipeline and nozzle was approximately linear, and no obvious turning phenomenon occurred in the area mutation region. This may have been due to the fact that when 𝛿≤1.5δ≤1.5, the cross-sectional area of the nozzle was not much different...
When is the best time to buy a gas grill? Aside from answering when you need one and have the budget for it, the other answer would be considering those factors and looking for sales. Generally, at the end of summer, you'll start seeing grills go on sale to make room for fall and...

and a much larger demonstration plant is set to start up in Shanghai later this year. Virgin plans to launch the fuel's first trialflights within the next 18 months, and is working to obtain approval for its use in commercial aircraft.Richard Branson, president of Virgin Atlantic, said that...
burned for internal energy generation within the production facility. Another large gas source, biomass gasification to generate fermentable syngas, is recognized as an alternative to lignocellulosic biomass to fuel conversion. Virtually any waste product can be recycled by turning this into syngas [3–...
