Not exact matches

The researchers think the skull is better for assessing sex because it's not a load - bearing bone, meaning it is subject to fewer outside forces — allowing forensic practitioners to detect bone mineral density differences that result from an individual's biological sex.

«The key here is gravity separation, which efficiently separates the fibreglass from the resin by using the differences in their densities.

These differences in density are caused by the interplay of the solar wind — the constant stream of charged particles from the sun — and the interplanetary magnetic field that stretches across the solar system.

Travelling between the stars for a hundred light years or so, we would find ourselves moving between regions where the density of gas changes a millionfold — more extreme than the difference between air and water — and with changes in temperature from just a few degrees above absolute zero to over a million degrees.

From these differences, Freire and his colleagues calculated the density of the intracluster gas, which they report in the 10 October issue of Astrophysical Journal Letters.

When the researchers matched the women who had a detected cancer with control participants of the same age and from the same locales who did not have cancer, they found no significant difference in mammographic density.

The colors represent differences in density: from lowest to highest density the colors are black, blue, pink, red, orange, yellow, and white (highest density peaks).

Kirchner, J.F., C.R. Bentley, and J.D. Robertson, Lateral density differences at a site on the Ross Ice Shelf, Antarctica, from seismic measurements, Journal of Glaciology, Vol.

Journal: E.D. Gennatas et al. «Age - related effects and sex differences in gray matter density, volume, mass, and cortical thickness from childhood to young adulthood.»

To demonstrate the predictive value of individual differences in morphometric patterns of gray matter density for intelligence, we applied voxel - based morphometry (VBM) on structural magnetic resonance imaging (MRI) data from 308 adult participants (Nooner et al., 2012).

The resolution has been reduced from 2560 × 1440 pixels to 2048 × 1536 pixels, but in regular usage the reduced pixel density doesn't make any difference unless you're looking at the screen up close.

The Atlantic overturning is driven by the differences in the density of the ocean water: when the warm, lighter water flows from south to north it becomes colder, denser and heavier, making it sink deeper and flow back southwards.

The upshot of the differences in air density that manifest between 400 hPa and 50 hPa is fast displacement of low density air that travels to the top of the atmosphere in a cone that surrounds the very cold dense descending air from the mesosphere.

So it's all gases at greatest density will be doing the same thing around the planet at the same time (*) and as these change with differences in density in the play between gravity and pressure and kinetic and potential from greatest near the surface to more rarified, less dense and absent any kinetic to write home about the higher one goes, then, energy conservation intact, the hotter will rise and cool because losing kinetic energy means losing temperature, thus cooling they which began with the closest in density and kinetic energy as a sort of band of brothers near the surface will rise and cool at the same time whereupon they'll all come down together colder but wiser that great heights don't make for more comfort and giving up their heat will sink displacing the hotter now in their place when they first went travelling.

This circulation, which extends from pole to pole and throughout every ocean, is powered by density differences in ocean waters in different areas of the world.

So what is the difference between the ocean and atmosphere of Venus from a «pure» density / pressure, IR absorption point of view?

From friction, chemical interaction, ignition, expansion / contraction, solar contribution, density differences, electricity, gravity, centrifugal force, circular motion, etc..

The observed differences between their study and our assessment can further result from variations in the base data employed: Jongman et al. [73] used a finer resolution SRTM grid at 3 arc sec resolution but coarser resolution population density data at 5 arc min resolution and, as mentioned earlier, an older version of the UN's demographic data.

Auto insurance rates change from one zip code to the next, primarily because of the differences in population densities, unemployment rates, median resident ages, median income levels, poverty rates, crime data, and the percentage of uninsured drivers on the road.

However, when aggregating data from multiple origins, for example within an industry vertical or geographic regions, be careful with the types of conclusions being drawn: adding up densities for the same metric across multiple origins does not account for relative population differences across origins.

The main difference between this panel and a traditional 1440p display is its length: it features an extra 400 pixels of vertical height, taking it from a 5.55 - inch 1440p 16:9 display (with equivalent pixel density) to a 6.2 - inch 2960 x 1440 18.5:9 display.

The difference in pixel density shouldn't mislead you: it's very hard to observe a difference between the screens of the Note 3 and the Galaxy S4, especially since you'll likely use the Note from a greater distance.
