We suggest that management practices may benefit from understanding the historical density of species and the evolutionary consequences of rapid and sustained density changes.
However, densely welded ignimbrites commonly result from progressive aggradation from sustained density currents [ Branney and Kokelaar, 1992] and therefore the overburden is an end-state and sintering, initiated at low axial stress and would be partially controlled by the processes we describe.
Wei et al. [14] demonstrated that multi-walled carbon nanotubes have extraordinarily high-current carrying capacity, sustaining current densities greater than 109 A/cm2.
We used a case control sampling frame to identify women with dense breasts (high-density phenotype) and women who never had high or moderate breast density on any of their mammograms in FMMP database, that is, have sustained low density on all mammograms throughout the cohort follow-up (low-density phenotype).
Low Cm dose reduced total neurite length by 43%, while pre-NaBt treatment optimized neuritogenesis with a sustained mitochondrial density despite high Cm concentration (Fig. 5d).
Jeffrey Tittel, director of the Sierra Club's New Jersey chapter, said the problem was that Roxbury's rolling terrain -- many hillsides were once mined for iron ore -- simply doesn't have the abundance of groundwater needed to sustain a density of development more appropriate to the lowlands.
Our results indicate that the formation of the Yamanlar caldera resulted from one major catastrophic eruption that generated several sustained pyroclastic density currents (PDCs) subdivided by fall deposits with sharp contacts.
The model can sustain large density differences across material interfaces without the presence of spurious oscillations in velocity and pressure, and it can accommodate realistic equations of state and arbitrary (pressure- or temperature-based) reaction-rate laws.
This suggests that the limited nutrient availability of AF could not sustain higher density growth.
It has been suggested that serum 25(OH D levels above 50 nmol/L are sufficient to sustain bone density and calcium absorption and to prevent osteomalacia [ 11].
VEGF with Ang-1 late delivery groups could increase and/or sustain vessel density, blood flow, and flow reserve, along with enhancing pericyte coverage at 8 weeks after ligation.
