Use of the deuterated-retinol-dilution technique to assess total-body vitamin A stores of adult volunteers consuming different amounts of vitamin A
DRD technique pool size isotope dilution
2016/6/1
The deuterated-retinol-dilution (DRD) technique
provides a quantitative estimate of total body stores of vitamin A.
However, it is not known whether the technique can detect changes
in vitamin A po...
Assessment of total body stores of vitamin A in Guatemalan elderly by the deuterated-retinol-dilution method
Vitamin A deuterated retinol dilution body stores

Deuterated retinol dilution (DRD) gives
quantitative estimates of total body stores of vitamin A.
Vitamin A assessment by the isotope-dilution technique: good news from Guatemala
Vitamin A isotope-dilution technique
2016/5/30
Unlike many vitamins, vitamin A is absorbed fairly well, is stored efficiently in the liver as well as in other organs, is recycled extensively within the body, and is catabolized irreversibly in heal...
Family size and intergenerational social mobility during the fertility transition: Evidence of resource dilution from the city of Antwerp in nineteenth century Belgium
Belgium demographic transition fertility nineteenth century parental investment quantity-quality trade-off resource dilution social mobility
2011/2/24
It has been argued in sociology, economics, and evolutionary anthropology that family size limitation enhances the intergenerational upward mobility chances in modernized societies. If parents have a ...
A Dilution Test for the Convergence of Subseries of a Monotone Series
Convergence Subseries of a Monotone Series
2010/11/24
Cauchy's condensation test allows to determine the convergence of a monotone series by looking at a weighted subseries that only involves terms of the original series indexed by the powers of two. It ...
What happened to the other Mohicans? Realistic models of metallicity dilution by fingering convection and observational implications
hydrodynamics instabilities turbulence planets and satellites
2010/11/16
When a planet falls onto the surface of its host star, the added high-metallicity material does not remain in the surface layers, as often assumed, but is diluted into the interior through fingering (...
Polarization-preserving confocal microscope for optical experiments in a dilution refrigerator with high magnetic field
Polarization-preserving confocal microscope optical experiments dilution refrigerator magnetic field
2010/11/11
We present the design and operation of a fiber-based cryogenic confocal microscope. It is designed as a compact cold-finger that fits inside the bore of a superconducting magnet, and which is a modula...
Traceable Amino Acid Analyses of Proteins and Peptides by Isotope-Dilution Mass Spectrometry Using Precolumn Derivatization Reagent
Traceable Amino Acid Analyses Proteins and Peptides Isotope-Dilution Mass Spectrometry
2010/9/17
We have developed an accurate and traceable quantitation method of proteins and peptides by isotope-dilution mass spectrometry with the precolumn derivatization for hydrolyzed amino acid. This method ...
Parameterization of subgrid plume dilution for use in large-scale atmospheric simulations
Parameterization subgrid plume dilution large-scale atmospheric simulations
2010/3/16
A new model of plume dynamics has been developed for use as a subgrid model of plume dilution in a large-scale atmospheric simulation. The model uses mean wind, shear, and diffusion parameters derived...
The Prediction of Waste Water Dilution by a Long-Term Tracer Experiment
Prediction Waste Water Dilution Long-Term Tracer Experiment
2009/10/29
In general tracer experiments made for the evaluation of waste water dilution
in recipients have been of short-term type, with the tracer having an injection
time that is markedly less than the time...
Discharge Measurements by a New-Formed Relative Salt-Dilution Method in Small Turbulent Streams
Discharge Measurements New-Formed Relative Salt-Dilution Method Turbulent Streams
2009/10/28
Water discharges in small turbulent streams are determined by injecting concentrated
salt solutions at constant feed-rate and measuring the dilution level
downstream by conductivity readings in situ...
