However, natural gas is lighter than air and explosive in air, whereas CO2 is nonflammable but toxic (and heavier than air). Their risk profiles are therefore not identical, and the differences in hazard certainly impact the nature of individual and societal risk. This study focuses on the ...

In an NCL, the heat sink is situated at a higher elevation than the heat source. This establishes a density gra- dient in the system, due to which, lighter (warmer) fluid rises up and heavier (cooler) fluid moves down. Hence thermal energy can be transported from a high temperature ...
For example, negative gradients will offset positive gradients, and lighter than average vehicle loads will offset heavier than average vehicle loads. A final point is that, in general, LGAs have more influence over congestion than for example gradient, vehicle loading, ambient weather, use of ...
High pressure fluid energy can be used for mechanical drive means for propulsion such as; wheels, or tracks for land vehicles, propeller screws, pumps, jets, or paddles for marine vehicles, or rotors, fans, or propellers for both heavier than air and lighter than aircraft. ...
Natural abundance 12CO2 forms hollow CNTs, while equivalent synthetic conditions with heavier 13CO2 favours closed core CNFs, as characterized by Raman, SEM and TEM. Production ease is demonstrated by the first synthesis of a pure 13C multiwalled carbon nanofiber. aOcannribenoccnlei,mnntaiavt...
Superscripts iand jdenote mass numbers of a heavier and a lighterisotope, respectively, so that the quantity of the heavier isotope is in the numerator and that of the lighterisotope is in the denominator.

During planetary evolution, differential escape of hydrogen and deuterium is thought to be the main mechanism for deuterium enrichment in the atmospheres (the lighter H escapes more easily than the heavier D). There are other proposed mechanisms for the enrichment of the D/H ratios including time...
Due to the rolling and drag resistance forces, it is clear that heavier and larger vehicles consume more energy/fuel than lighter ones, which in turn results in higher driving emissions [58]. Additionally, since more material is needed for producing heavier vehicles, the production emissions are...
than the considered pressure range of 3–7 MPa. The interaction parameters in mixed gas that influence the solubility of gases in liquids resulting in gas hydrates formation tend to allow the lighter gases to be dissolved more when compared to that of the heavier gases39. This could be a ...
