It is one of the virtues of Quint's book (another is the generosity of critical annotation, amounting almost to a mini variorum edition) that Paradise Lost's still center is given a density so great that reading the poem becomes itself a heroic act; an act difficult to perform, but in its difficulty providing an experience few (if any) efforts of the human imagination are capable of provoking.

We now know the shape of the universe (flat) and the average density of matter and energy (critical density), and yet we don't know what will happen.

In the simplest cosmological model, critical density just means that the inward pull of gravity is exactly strong enough to halt the outward expansion of the universe.)

The same thing held our species back, until the population reached a critical density, unleashing the power of culture — at which point there was no stopping us.

The simulations demonstrated that the critical factor is particle density — in other words, the total concentration of subunits in the system: In a system in which the particle density is low, opportunities for interaction are few, and individual filaments are widely separated.

Nonetheless, because low - density infections without disease symptoms are expected to become increasingly common as countries improve malaria control, ultra-sensitive tools such as these will likely be critical for malaria surveillance and for monitoring the progress of malaria control and elimination programs.

In a recent study examining a long - term DNA dataset of grizzly bear activity in British Columbia, Lamb and his colleagues conclusively determined what scientists have long suspected: higher road density leads to lower grizzly bear density, a critical problem for a species still rebounding from a long period of human persecution.

A lithium - sulfur cell can have almost double the energy of a lithium - ion cell for the same mass, yielding an edge where energy density is critical, like in portable electronics or in cars.

Homer 1, an actin binding protein that is induced by BDNF [72], belongs to a family of scaffolding proteins that localize at the postsynaptic density (PSD)[73, 74] and is believed to play a critical role in signal transduction, synaptogenesis and receptor trafficking at synapses [75].

Gravity will ultimately determine the fate of the expansion, and gravity is dependent upon the mass of the universe; specifically, there is a critical density of mass in the universe of 10 - 29 g / cm3 (equivalent to a few hydrogen atoms in a phone booth) that determines what might happen.

Some of the risks include decreased bone mineral density, increased blood pressure, headaches, and difficulty sleeping, and sleep is one factor that is critical to weight - loss.

Indeed, unlike animal protein, plant protein has not been associated with increased insulinlike growth factor 1 levels28, 29 and has been linked to lower blood pressure,30 - 32 reduced low - density lipoprotein levels,32 - 34 and improved insulin sensitivity.35 Substitution of plant protein for animal protein has been related to a lower incidence of CVD36 - 39 and type 2 diabetes.40 - 42 Moreover, although a high intake of red meat, particularly processed red meat, has been associated with increased mortality in a recent meta - analysis of 13 cohort studies, 43 high consumption of nuts, a major contributor to plant protein, has been associated lower CVD and all - cause mortality.44 These results underscore the importance of protein sources for risk assessment and suggest that other components in protein - rich foods (eg, sodium, 45 nitrates, and nitrites46 in processed red meat), in addition to protein per se, may have a critical health effect.
