This gas appears to be the most variable minor constituent in the atmosphere of Mars.
Various improvement strategies are feasible, depending on whether the phytochemical target is a major or minor constituent.
Praseodymium is a minor constituent of misch metal, which is used to make lighter flints and as alloying additions to ferrous and nonferrous alloys.
Because of their relative instability to chemical weathering at the Earth's surface, amphiboles make up only a minor constituent in most sedimentary rocks.
The S phase is observed to nucleate within the hardening plateau, but remains a minor constituent until the end of this stage.
Such warm dark matter is not to be confused with hot dark matter, highly energetic particles like neutrinos that are now thought to be a minor constituent of cosmic mass.
Although water is only a minor constituent of the Martian atmosphere (a few molecules per 10,000 at most), primarily because of low atmospheric and surface temperatures, it plays an important role in atmospheric chemistry and meteorology.
Although tin is usually a minor constituent in alloys, it is an essential one on account of the way in which its special properties confer improvements to the matrix metal.
Although the extracellular matrix (ECM) is only a minor constituent of the liver, it has a fundamental role, providing a structural framework and maintaining the differentiated state of all liver resident cells.
Overall, Microcystis was a minor constituent of the phytoplankton community above Copco and Iron Gate Reservoirs, although it was highly prolific within these reservoirs and our data indicate that most of these populations originate internally.
The measurement of two isotopic species using lines of similar strength but very unequal concentrations leads to low precision, with either the minor constituent having too small an absorption depth, or the major constituent having too great an absorption depth.
