Ballast for flight tests. The load, or weight, and balance of an aircraft is one of the most important elements in flight testing since it affects both performance and stability. By using tungsten alloy as ballast during flight tests, it is possible to simulate different payloads and small compact weights to be placed in precise positions.

· The role of dust as ballast mineral for organic carbon, however, must be also taken into consideration in the coastal settings off NW Africa. There, high settling rates of larger particles approach 400 m day−1, which may be due to a particular composition of mineral ballast.
· Because mineral ballast, notably CaCO 3, is found to play a dominant role in carrying organic matter through the water column, a reduction of its export fluxes weakens the strength of the biological carbon pump. There is, however, a third effect with severe consequences: Because organic matter is oxidized in shallow waters when mineral-ballast ...

· In this case, our results are in keeping with recent literature arguing that ecosystem structure is more important than ballast mineral in driving the T eff in high-latitude diatom-dominated regions [Assmy et al., 2013; Henson et al., 2012; Lam et al., 2011; Wilson et al., 2012], although in the SO, too, it has been shown that the collapse of a ...

· The major conclusions that have been drawn from these correlations are that organic matter sinking in the sea is "carried" down by such mineral "ballast" [Armstrong et al., 2002], and that the primary mineral responsible for the sedimentation of POC is calcium carbonate [François et al., 2002; Klaas and Archer, 2002].
''''ballast'''' model to the ratio of organic carbon to calcium carbonate in the deep sea (the rain ratio). We distinguished three forms of mineral ballast: calcium carbonate, opal, and lithogenic material. We concur with Armstrong et al. [2002] that organic carbon sinking fluxes correlate tightly with mineral fluxes. Based on the correlations
rocks of identical mineral composition having dif ferent textures would have different names. Mineral identification is generally based on simple tests that involve hardness, cleavage, luster, ~streak color, and chemical composition. From a ballast per formance viewpoint, mineral hardness, generally
Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. Ballast also holds the track in place as the trains roll over it.
