An Antarctic Intermediate Water origin is inferred as driving mechanism for the drift development, although glacial conditions are not yet well constrained.
However, the full range of conditions over which zircon is able to deform by crystal-plastic processes has not yet been constrained, and currently there are no published studies that systematically test the extent to which a given population of zircon grains can be affected by rock deformation.
The processes that control the organic composition of the fluids are not yet fully constrained or understood.
The description of the phenomenon should be comprehensive yet constrained to relevant features.
The upper boundary at shallower depths has not yet been well constrained, but has been estimated through interpolation from the location of the PAC upper boundary at a depth of 40 km and the trench axis.
Such a quantitative analysis for ternary feldspar is hampered because the mobility of the anorthite component is not yet well enough constrained.
Sadly, most of the modern diagnostic tests have not yet become available in resource constrained countries [ 3], which concentrate 95% of world's TB cases and 98% of deaths [ 1].

The summer in which Betty goes missing is a liminal one for her too: a period in which she has shaken off the supervision of formal education but has not yet begun to be subdued and constrained by employment.
In many nations industrial scale AD of non-agricultural waste materials (such as MSW) has not yet reached its full potential, often constrained by the lack of secure, inexpensive, high quality AD feedstocks, and markets for the resulting digestate material.
