Texture alterations accompanying grain growth have been simulated by means of a new statistical model which for the first time takes into account the dependence of both the energy and mobility of grain boundaries on their disorientation.
Numerous investigations have demonstrated that the effect of UV-B enhancements on plants includes reduction in grain yield, alteration in species competition, susceptibility to disease, and changes in plant structure and pigmentation.
At 600 °C, the grain underwent chemical alteration (Supplementary Figure 3), likely through a reaction with the surrounding olivine, as the TEM operates in high vacuum.
In addition, for loess samples with minimal pedogenic alteration, grain size-dependent parameters (e.g., B c) could be good indicators for the strength of Asian winter monsoons.
In addition to these theoretical and observational studies, therefore, experiments on the laboratory synthesis of PAHs and their grains are necessary to understand the formation and subsequent growth into PAH grains and their alteration upon UV irradiation in various objects.
The most likely material to have retained this field information is dusty olivine: assemblages of nanometric low-Ni kamacite grains protected from alteration by their host olivine crystal, found in the chondrules of unequilibrated primitive chondrites1,2.
Compared with the base material, the striation zone on the non-smooth surface was mainly characterized by the refinement of grains and the alteration of microstructure.
Mikami et al. (2008) studied the allelic diversification at the Wx locus in Asian rice associating different alleles to grain amylose content alterations.
The scanning transmission electron microscopy study with nanometer scale resolution for composition analysis has elucidated the alteration in grain structure of CoFe films due to Fe(OH 3 incorporation.
The simulator is based on the solution of the equations of fully coupled fluid flow, species transport and rock/fluid reactions and includes the effects of grain growth/dissolution and the alteration of porosity and permeability due to mineral reactions.
