Comparability of calibration strategies for measuring mercury concentrations in gas emission sources and the atmosphere [PDF]
Atmospheric Measurement Techniques, 2021 A primary mercury gas standard was developed at Van Swinden Laboratory (VSL) to establish an International System of Units (SI)-traceable reference point for mercury concentrations at emission and background levels in the atmosphere.

Predicting specific gravity and viscosity of biodiesel fuels [PDF]
, 2009 Biodiesel is a promising non-toxic and biodegradable alternative fuel in transport sector. Of all the biodiesel properties, specific gravity and viscosity are the most significant for the effects they have on the utilization of biodiesel fuels in ...

DENSITY AND VISCOSITY EQUATION OF BLEND OIL [PDF]
Romanian Journal of Petroleum & Gas Technology, 2021 Extracted oils and gases have different physical and chemical properties, depending on oil structures. Thus, it is beneficial to create mixtures of oils by combining cheaper crude oils with variants that have better properties (Brent type).

Geophysical Journal of the Royal Astronomical Society, 2010 Direct and indirect estimates of the variation of viscosity with depth in the mantle indicate that a low viscosity layer exists in the upper mantle. A viscosity varying with depth can be used to reconcile the various estimates of relaxation times. If the seismic anelasticity can be used as a guide the average viscosity of the lower mantle is about 10 ...
