In the Proterozoic, the concentration of atmospheric oxygen was high enough to prevent formation of mass-independent fractionation of sulfur isotopes, thus allowing detection of small mass dependent multiple sulfur isotope effects produced by microbial and chemical transformations of sulfur species.
This removes any nuclei which will encourage precipitation or formation of masses of small crystals.
One of these phenomena is the formation of masses of particles, due to their oil content, which increases resistance to mass transfer inside the particle.
Peptide mapping and mass spectrometric analysis revealed that covalent modifications by citric acid led to the formation of amides (mass increase of 174 Da) and/or imides (mass increase of 156 Da) at the N-terminus of the light chain.
The gravitational collapse of heavy stars is assumed to be responsible for the formation of stellar mass black holes.
The uncontrolled cellular growth results in the formation of a mass of cells commonly referred to as a tumor.
Because an elevated cell-turnover rate in the colon epithelium could in part explain the formation of the mass lesions, a bromodeoxyuracil (BrdU -incorporation study was conducted.
The rapid formation of the mass, the impressive surgical and histological findings in the surprising absence of substantial wear, and only moderate levels of ions may be explained by heightened sensitivity.
In a study of 159 females, Angus et al found that forearm BMD was positively correlated with Fe, Zn, and Mg intake, and suggested that nutritional factors other than calcium play a role in the formation of bone mass.
When NPs were created with Ch50, it was shown that they are dispersed in buffer, but some aggregation and formation of a mass of large particles may be seen.
