The Chemical Enrichment of the First Galaxies
AIP Conference Proceedings, 2010Using three‐dimensional cosmological simulations, we study the assembly process of one of the first galaxies, with a total mass of ≃108 M⊙ collapsing at z≃10. We trace the transport of the heavy chemical elements produced and dispersed by a pair‐instability supernova exploding in one of the minihalo progenitors.

Chemical Enrichment of the Intra-Cluster Medium
Astrophysics and Space Science, 2003We investigate the metal enrichment of the intra-cluster medium by using a method that combines N-Body simulations and a semi-analytic model (SAM) of galaxy formation. The cluster of galaxies is simulated in a flat, low density universe, with a numerical resolution that allows the detection of substructures in the dark matter background of the cluster.

Chemical Enrichment of Nickel Sulfide ()
International Journal of Nonferrous Metallurgy, 2016 The availability of polymetallic ores is getting leaner in grade and is larger but inferior in volumes than in the past, making the extraction of copper, nickel and other non-ferrous metals metallurgically more difficult to produce. The standard technologies, including enrichment and concentration, do not provide methods for obtaining monometallic ...

Chemical Labeling and Enrichment of Histone Glyoxal Adducts
ACS Chemical Biology, 2022Because of their long half-lives and highly nucleophilic tails, histones are particularly susceptible to accumulating nonenzymatic covalent modifications, such as glycation. The resulting modifications can have profound effects on cellular physiology due to the regulatory role histones play in all DNA-templated processes; however, the complexity of ...

Chemical enrichment in the early galaxy
Astrophysics and Space Science, 2003New, precise abundance data for a large number of elements in a growing sample of extremely metal-poor stars are accumulating from the new 8-m telescopes. Combined with theoretical models, these results advance our understanding of the first generations of stars, whose nucleosynthesis products are fossilised in the oldest stars we see today and thus ...

Chemical enrichment by massive stars
New Astronomy Reviews, 2000Abstract Heavy element abundances derived from high-quality ground-based and Hubble Space Telescope (HST) spectroscopic observations of low-metallicity blue compact galaxies (BCGs) with oxygen abundances 12+log O/H between 7.1 and 8.3 are discussed. None of the heavy element-to-oxygen abundance ratios studied here (C/O, N/O, Ne/O, Si/O, S/O, Ar/O, Fe/

Effect of enrichment on chemical properties of MSW compost
Bioresource Technology, 2010The efficacy of inorganic additives (rock phosphate 5%, FeSO(4) 1%, and lime 0.63%) meant to perk up the Municipal Solid Waste composting process and to examine the physico-chemical parameters during composting in mechanical composter. Swiftly rise in temperature from mesophilic to thermophilic stage was accompanied by an increase in NH(4)(+)-N that ...
