This study will greatly improve the number and quality of
density measurements of the outer - belt asteroids, to a degree not possible before TMT.
Even though
density measurements suggest that Ceres is roughly one third water by weight, water ice should rapidly sublimate away into space on the dwarf planet's airless, sun - soaked surface, so its absence at first would seem to be no surprise.
Researchers from The University of Manchester's Jodrell Bank Centre for Astrophysics have developed and demonstrated a process for continuous
electron density measurement of the previously under - explored D region of the ionosphere — a part of the atmosphere that previously could only be sensitively probed by short - lived rocket - borne instruments.
They then analyzed associations between the genetic variants and bone mineral
density measurements taken in more than 53,000 people.
Many of the planets discovered by EDEN around nearby stars will be suitable for in - depth atmospheric characterization, mass, radius, and
bulk density measurements through follow - up observations with large ground - and space - based telescopes, such as NASA's James Webb Space Telescope.
«This is the first time we have synaptic
density measurement in live human beings,» said Carson, who is senior author on the study.
In our new paper we worked with Mark Giampapa — a solar / stellar astrophysicist — on the first comprehensive study of this effect and its impact on transit spectra and
exoplanet density measurements.
LGGE — Alain Hubert, Nighat Amin and Simon Steffens to carry out
snow density measurement — traverse of 180 km, measurement of 60 points, twenty cores to measure snow density.
To ascertain the annual balance of a glacier from a sparse network of observations is optimized by detailed mapping of mass balance across the glacier determined from a high -
density measurement network during several years.
The results from the Firnschrumpfschreiber and
from density measurements in the walls of the shaft showed that the compaction rate decreases, and the density increases, with depth.
Designed and tested 1MHz / 5 MHz R.F. amplifier board for
sludge density measurement product using high gain, high frequency op - ampl., resulting in reduced cost, smaller size and superior performance.
On the other hand, in magnetic field confinement fusion plasma intended for a fusion reactor, which research is being conducted at the National Institute for Fusion Science, development of high precision
electron density measurements is becoming an important research topic.
A new study published today in The Lancet reveals that a simple questionnaire, combined with bone
mineral density measurements for some, would help identify those at risk of hip fracture.
Currently,
breast density measurements have been used to track changes in density patterns which occur over time or with medical treatment, such as with Hormone Replacement Therapy (HRT).
The present sub-study included 2,167 women who underwent
bone density measurements in 1999, and out of these women, 1,147 took part in follow - up measurements ten years later, in 2009.
A new analysis has found that a single bone
density measurement and an assessment of fracture history in postmenopausal women can predict fracture risk over a much longer period, up to 25 years.
We need to have breast -
density measurements that are standardized, reliable and reproducible.
The density measurements suggest that at least the innermost six are probably rocky in composition.
These density measurements dictate the possible chemical composition of these strange, but ubiquitous planets.
The density measurements suggest that the planets smaller than Neptune — or mini-Neptunes — have a rocky core but the proportions of hydrogen, helium and hydrogen - rich molecules in the envelope surrounding that core vary dramatically, with some having no envelope at all.
A Collection of Famous Articles by John Lee M.D.. Here's a wealth of information about osteoporosis including bone
density measurements, HRT, progesterone, estrogen, prevention, treatment and diet.
Of equal importance is that the range of density variation is of the same order as
the density measurement error, determined through repeat measurements.
Of equal importance was that the range of density variation is of the same order as
the density measurement error, determined through repeat measurements.
Thus,
density measurements are no longer completed during crevasse stratigraphy or probing.
Examples of this type of data include tree ring width and
density measurements, fossilized plant remains, insect and pollen frequencies in sediments, moraines and other glacial deposits, marine organism fossils, and the isotope ratios of various elements.
