If surface anomalies in the composition of the metallic-line A stars (Am stars) are due to a precipitation of planet-like bodies (planetoids) on them, then one should expect a correlation to exist between the overabundance of heavier-than-iron elements on these stars and their "standard" ...
Soil is one of the most important things for life to exist on earth. Its chemical composition and environmental effects are essential to understand if one truly wants to look at its importance. In this lesson, explore what soil is made of, the different types of soils, and some environmental...
, 1996).At the beginning of the twentieth century Harkins at the University of Chicago thought that meteorites would provide a better estimate for the bulk composition of the Earth than the terrestrial rocks collected at the surface as we have only access to the "mere skin" of the Earth. ...

Similar to our recent study [27], all genomes were processed using the command-line version of antiSMASH v6.0.1 with the bacterial setting and otherwise default parameters [28]. The number of each class of BGCs and the necessary information regarding the composition of the BGCs in these genome...
Another phenomenon that may occur is re-release of pollutants to the environment under appropriate conditions. The re-volatilisation of volatile and semi-volatile compounds during the warmer months, and surface runoff of organic and inorganic composition (the so called ‘spring pulse’) may cause ...

(Aloupi-Siotis2008) followed by peptization and precipitation (Winter1978). The finest clay fraction was finally thickened via evaporation to produce a concentrated clay paint. The use of raw clays rich in illitic clay minerals is explained by their chemical and mineralogical composition (rich in...
In the current experiment, the sample was exposed to four discharges with an exposure length of 3 s in each discharge at extremely high thermal loads. The test results are compared with our previous investigations of deposited layers obtained in the DIII-D divertor region. The plasma discharge ...
In future development of the continuous process, several parameters should be tuned to match the rates of the bromate formation and decomposition in the electrolytic and catalytic cells. In the electrolytic cell, the applied current, electrode size and electrolyte composition and volume should be ...
