And coil of the prevailing words
Close round its being, and compress

Whence, beneath love's soft compressing,
As from flowers, sweet perfumes start.

Her aim flew at his apron-band,
That he might see and understand.

Down through mines, and crypts, and caves,
Still graves on graves, and graves on graves,
Down to earth's most central fires.

"And my ample form much smaller grew,
By the cold compressed to a drop of dew;
Then down I fell, swift as bounding deer,
And knew no more till I fell right here;
But how I became so like a feather
Is problem I can unravel never.

In the first case the density ρ first increases, then reaches a plateau value that depends on the compression speed: the slower the compression, the higher the value.
Aging in a simple model of a structural glass
In a system where the metastable phase is more or less compressible, a finite compressibility acts to reduce a portion of the liquid taking part in the hydrodynamic mass flow and hence the overall kinetic energy, leading to an exponential increase in the quantum nucleation rate.
Effects of hyperons on the dynamical deconfinement transition in cold neutron star matter
The M-H curves in Fig. 1b show that the 5 % compression of the sample along B direction results in the sample texture, which is very similar to that for the single variant martensite with c-axis, which is indeed the easy axis of magnetization, along the compression direction.
Large Magnetic-Field-Induced Strains in Ni-Mn-Ga Alloys due to Redistribution of Martensite Variants
The subsequent compression of the sample along direction A leads to the axial texture reorientation of about 900 , thus the c-axis and consequently the easy axis of magnetization again coincides with a compression direction (see Fig. 1c).

Without loss of generality, suppose that three judges are asked to build extracts of a single article4. As an example, Table 5 shows the weights of the different sentences (note that no compression rate needs to be specified; from the data in the table, one can generate summaries at arbitrary compression rates).

In Table 10 we show the normalized performance (D) of MEAD, for the six clusters at nine compression rates. MEAD performed better than Lead in 29 (in bold) out of 54 cases. Note that for the largest cluster, Cluster D, MEAD outperformed Lead at all compression rates.

The Doppler effect generates smaller peaks that are 90 degrees out of phase with the compression mode, and the effect of enhancing the baryon component is to strengthen the compressions relative to the rarefactions because of the baryonic contribution to the gravity .
