Fossil CO2 emissions have been diluting the global 14C/C ratio of atmospheric CO2 (Suess effect). We estimated the 14CO2 amount in the atmosphere (and its trend) utilizing the calculated 14CO2 activity concentration in the atmosphere (aacn, reported in mBq m–3). This parameter, calculated from Δ14CO2 and the CO2 mixing ratio (reported in micromoles of CO2 per mole of air), is connected with the 14CO2 quantity in the volume or mass unit of air, which is not influenced by the Suess effect. This parameter can only be influenced by processes linked to 14CO2 emissions/uptake, e.g. associated with atmosphere-biosphere or atmosphere-ocean CO2 exchange as well as by anthropogenic emissions of 14CO2. Results obtained from measurements at Schauinsland station, Germany, indicate a stable amount of 14CO2 in the atmosphere since the early 1990s.

Ján ŠimonThis paper deals with measurement of emissivity of the composite samples. Three composite samples with the different thickness are heated to the temperature sixty-five degrees Celsius. On each sample must be applied a known emissivity coating. Unknown emissivity is calculated using the information obtained during the measurement. The aim of this paper is to show one of the possible approaches to find out the emissivity of the composite material.
About Me
Ján Šimon was born in 1980 in Martin, Slovakia. He studied at the Faculty of Mathematics, Physics, and Informatics at Comenius University in Bratislava, where he completed the master's degree in environmental physics (2004). He continued in studies of nuclear and subnuclear physics at the same faculty, where he completed PhD. degree in 2010.
He currently works at the Department of Applied Mathematics on the Faculty of Mechanical Engineering at the University of Žilina where he is giving lectures on mathematics and conducting research in field of applied nuclear physics, knot efficiency related theoretical and experimental problems, general mathematics and statistics.
Outside the field of employment, he’s active climber, ski-mountaineer, mountain rescuer, the head of the expert commission in Slovak mountaineering association (SVTS).
