of this critical density.

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.
Specifically, intensive postmortem neurological studies
of their brain tissues reveal a relatively low
density of acetylcholine (a neurotransmitter) nerve sites, which, at normal
densities, function in
critical ways to help re-initiate breathing following a sleep - related apnea or extended breathing pauses.
But the cloud would never reach that
critical density without some way
of cooling down, thereby reducing the pressure
of the gas.
Building them in 3D is
critical if they are to rival the
density of transistor - based designs.

of water point to the possible existence
of two different liquid phases — one with high
density and the other with low
density — that become identical at a liquid - liquid
critical point in the supercooled phase (C ′, see the figure).
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.)
When more hydrogen settles onto the star and heaps up to a
critical density, another explosion occurs, releasing another burst
of X-rays, and so on.
According to a study in the New Journal
of Physics, traffic jams develop spontaneously when vehicle
density exceeds a
critical level, beyond which minor fluctuations in the flow
of individual vehicles destabilize the whole thing.
Last February, Charles Bennett
of NASA's Goddard Space Flight Center announced the result: The overall geometry
of the universe is flat, meaning the amount
of mass and energy exactly matches the
critical density.
The main conclusion
of the JQI work is that the
critical density is greater than the threshold
density, so that there is a «sweet spot» for further development
of a Ps gamma - ray laser.
Using first - principles quantum theory, the JQI team has explored the time evolution
of a Ps BEC containing various mixtures
of spin - 0 and spin - 1 Ps atoms, and has found that there is a
critical density of Ps, above which collision processes quickly destroy the internal coherence
of the gas.
In the copper - oxide material, instead
of raising the temperature, the scientists raise the level
of doping to «melt» the
density waves at a particular «
critical point.»
«And the materials retain the low
density of the pure semicrystalline polymerso that we can keep the weight
of a structural component low, a property that is
critical to applications such as cars and planes, where weight is a
critical consideration.
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.
I am
of the persuasion that the breastfeeding Mother's diet is
critical to the nutrient
density of her breastmilk.
With more than 10 times the daily recommended amountof vitamin K, in addition to a range
of other minerals
critical for bone health, kale is a great choice for boosting bone mineral
density.
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.
Dead Rising 3 was a great third party title but only available on the Xbox One (later made available on PC) and focused on
density by throwing in massive numbers
of undead combined with the over the top top humour, an open world and cooperative play antics that achieved moderate
critical success.
As water can exist in several distinct states (solid, liquid or gas) and move from one to another, a human society may also be seen as a material capable
of undergoing these changes
of states as it reaches
critical mass in terms
of density of settlement, amount
of energy consumed or even intensity
of interaction.
The present section describes empirical models
of the TEC, the F - layer
critical frequency foF2, and the height

Now I am
critical of the WGI graphic (but not really the text), if they had chosen the label «Likelihood» and not «Probability
Density», (they indicate in the text that these are the same), that would have been more objectively true.
When designing and building high
density apartment and housing developments, the attention, so often lacking, to acoustic performance, can have a
critical impact on the quality
of life
of the buildings» inhabitants, as leading acoustic consultant Jim Dunne, Managing Director
of Integrated Acoustic Solutions explains
Maybe the real
critical things like weight distribution, proportional
density, wing shape, response time
of flaps and rudder, and engine power output, needed more consideration, modification?
In 2005 worldwide CO2 emissions amounted to nearly 28 Gt; even if were to set out only a modest goal
of sequestering just 10 %
of this volume we would have to put away annually about 6 Gm3 (assuming that all
of the gas is compressed at least to its
critical point where its
density is 0.47 g / mL).
