It changes, by the gradually increasing assumption of silicate material, first into a "lithosporic" shell—one in which silicates (especially olivine and pyroxene) are included sporadically in the metal, and then into a "ferrosporic" shell, in which gradually decreasing amounts of metal occur...

The chemical composition of the middle atmosphere (composed of the troposphere, stratosphere, and mesosphere) and its changes in the 21st century are considered. The initial data were obtained from the interactive two-dimensional radiation–chemical model SOCRATES, which calculates the height profiles ...
and Pioneer Venus5,6 spacecrafts stimulated us to study the chemical composition of the subcloud atmosphere of Venus in terms of the thermochemical equilibrium calculations, comparison of typical mixing and chemical times and a rule of height-independent element mixing ratio in the absence of condensa...
defines the current subject. Dalton’s theory provided a basis for understanding the results of earlier experimentalists, including thelaw of conservationof matter (matter is neither created nor destroyed) and thelaw of constant composition(all samples of a substance have identical elemental compositions...
The effect of chemical composition of the sintering atmosphere on the density, micro-structure and mechanical properties of Fe-3%Mn-(Cr)-(Mo)-0.3%C is described. Pre-alloyed Asta-loy CrM and CrL, ferromanganese and graphite powders were the starting powders. Following the pressing in rigid die...
Chemical analysis, chemistry, determination of the physical properties or chemical composition of samples of matter. A large body of systematic procedures intended for these purposes has been continuously evolving in close association with the developmen
USING THE HIGH-RESOLUTION X-RAY SPECTRUM OF PSR B0656+14 TO CONSTRAIN THE CHEMICAL COMPOSITION OF THE NEUTRON STAR ATMOSPHERE S. Schulz, "Using the high-resolution x-ray spectrum of psr b0656+14 to constrain the chemical composition of the neutron star atmosphere," ... HERMAN L. MARSHALL,...
carduchorum may contribute to the wound healing effects of the plant, as they can be released by rubbing the leaves on skin lesions. In this paper, we report, for the first time, the chemical–physical properties and the composition of the essential oils isolated from the aerial parts (OCA...
This study aims to investigate the performance of high-fidelity air quality models in simulating surface PM2.5 chemical composition over the East Asia region in terms of a prediction consistency, which is a prerequisite for accurate air quality forecasts and reliable policy decision. The WRF-Chem (...
