Publikováno v: Atmospheric Measurement Techniques, Vol 13, Pp 4051-4064 (2020)
Atmospheric flask samples are either collected at atmospheric pressure by opening a valve of a pre-evacuated flask or pressurized with the help of a pump to a few bar above ambient pressure. Under humid conditions, there is a risk that water vapor in

Oxygen isotopic signature of CO2 from combustion processes
Autor: W. A. Brand, H. Geilmann, H. G. Jansen, H. A. J. Meijer, R. A. Werner, M. Schumacher, R. E. M. Neubert
Publikováno v: Atmospheric Chemistry and Physics, Vol 11, Iss 4, Pp 1473-1490 (2011)
For a comprehensive understanding of the global carbon cycle precise knowledge of all processes is necessary. Stable isotope (13C and 18O) abundances provide information for the qualification and the quantification of the diverse source and sink proc

Publikováno v: Metrologia, 52(6), 827-834. IoP Publishing
This paper is the second of two articles on the quantification of isotope effects on the triple point temperature of water. In this second article, we address the combined effects of 18O and 17O isotopes. We manufactured five triple point cells with

Development and degeneration of retina inrdsmutant mice: ultraimmunohistochemical localization of S-antigen
Autor: Gustavo D. Aguirre, S. Sanyal, T. van Veen, H. G. Jansen
Publikováno v: Current Eye Research. 9:903-911
In the developing photoreceptor cells of the homozygous rds mutant mice S-antigen is localized over the ciliary protrusion as in the control mice, and to a lesser extent over the inner segments, perikaryal cytoplasma and the cell terminals. As the ou
