The journal is published six times a year, and we also publish conference proceedings and monographs on topics related to our fields of interest.
We're not here to debate matters like eschatology, baptism, or Bible translation.
Landscape Archaeology is a bridge between archaeology and environmental sciences though many consider it an environmental science in its own right.
It has become an important relic for many Catholics.
Running one sample at a time enables us to check for inorganic residue post combustion. Very high fluorine levels (60%) can cause high nitrogen results. If completely unknown, the operator will select about 2 mg for analysis.
This equipment does well in the analysis of air-sensitive samples.
It is produced, however, in the interior of stars in the horizontal branch, where stars transform a helium core into carbon by means of the triple-alpha process.

Atomic weight 12.01, Atomic Number 6, Melting Point 3550 C, Boiling Point 4,827 C.
Carbon occurs in all organic life and is the basis of organic chemistry.
This nonmetal also has the interesting chemical property of being able to bond with itself and a wide variety of other elements, forming nearly ten million known compounds.
When combined with both oxygen and hydrogen it can form many groups of compounds including fatty acids, which are essential to life, and esters, which give flavor to many fruits.
The isotope carbon-14 is commonly used in radioactive dating. Its different forms include the hardest naturally occurring substance (diamond) and one of the softest substances (graphite) known.
Since the heat conductivity depends upon it’s composition, the mixture of remaining gasses is sensed. Later the CO2 is removed and finally only N2 remains. The instrument is calibrated using various standards from the NIST.
