However, by comparing the abundance of the elements with their approximate position in the trend line, some elements appear excessively depleted in the silicate Earth, such as Se and Br, suggesting depletion could be attributed to a combination of both volatility and dissolution or assimilation into...
For example, the atmosphere is rich in nitrogen and oxygen but contains little carbon and hydrogen, while the earth’s crust, although it contains oxygen and a small amount of hydrogen, has little nitrogen and carbon. In spite of their differences in abundance, all elements and the chemical ...

Water pressure was excellent and hot water was available in abundance. Beds are firm but they suit me. Linen clean. Pillows probably need to be changed. Four bottles of Crystal brand drinking water is provided (just like high end hotels) so was very impressed with this. Also an in-room ...
All of these events (possibly with the exception of X-ray bursts) eject material with an abundance composition unique to the specific event and lead over time to the evolution of elemental (and isotopic) abundances in the galactic gas and their imprint on the next generation of stars. In ...
The synthetic motif sequences that were transcribed to RNA were recovered using reverse-transcription PCR, and the abundance of each sequence was then quantified by massively parallel sequencing (Methods). Comparison of the median activities of the individual TF consensus sequences revealed that several...
spread in everydirection, so clearly manifest in advanced stages in the evolution of astar, has its birth in the helium stage of evolution. There is apparentlynothing systematic in the motions directed away from the plane of thestars.THE ABUNDANCE OF THE ELEMENTS IN RELATION TO THEHYDROGEN-...

Recent abundance measurements in damped Lyman-alpha galaxies, supplemented with unpublished Keck observations, are discussed. The metallicity distribution with cosmic time is examined for clues about the degree of enrichment, the onset of initial star formation, and the nature of the galxies. The rel...
Examination of genomic DNA from several laboratory strains indicates that Ty4 is present in two to four copies. Ty4 mRNA is of low abundance as compared to other Ty retrotransposons. At the 3' end of Ty4, two "solo" delta-elements, a full length and an overlapping, truncated one, are ...
