The abundance of certain isotopes used for dating is determined by counting the number of disintegrations per minute (i.e., emission activity).
Not yet, maybe, but you can't be around him without noticing an abundance of certain qualities — self-confidence, energy, ambition, and the ability to drive curators bonkers, to name four — that could make him a contender.
In the winter, the protozoans prevailed owing to the abundance of certain testate amoebae and Ammonia sp. (Fig. 2).
Also, the abundance of certain species varied between farmland adjacent to and remote from forest edges, in both seasons.
As touched above, high abundance of certain microorganisms at examined (typically disturbed) process conditions does not necessarily mean that these microbes are also highly active.
For her master's research, she investigated how the abundance of certain radioactive elements in meteorites is connected with variations in solar activity.
This has been performed via detection of the abundance of certain elements namely calcium and magnesium in malignant tissues with respect to the non-neoplastic ones.
The relative abundance of certain elements (Ca) in flaring plasma heated to several million Kelvins (MK) is known to vary up to the factor of around 4 from flare to flare.
Detection of cytoplasmic HDAC6 substrates is often hindered by the high abundance of heavily acetylated histones and other proteins in the nucleus or mitochondria, and possibly low abundance of certain acetylated proteins in the cytoplasm.
Managers may be able to use these differential thresholds of response to harvest intensity to develop silvicultural prescriptions specifically intended to increase or decrease the short-term abundance of certain life forms.
By use of fluorescence spectroscopy, the relative abundance of certain tube chiralities has been seen to increase in the bimetallic samples compared to the monometallic ones as for example the (6,5) nanotube.
