Preferential recycling of nutrients - the ocean's way to increase new production and to pass nutrient limitation?
(1999-12)
Uptake of atmospheric CO2 by the oceans and the export of carbon into deeper waters via the biological CO2 pump is driven by the production of particulate organic matter (POM). The elemental ratios of carbon, nitrogen, and ...
Carbon cycle research after Kyoto
(1999-04)
Recent progress in research of the global carbon cycle is reviewed and research needs for the immediate future are discussed, in light of the challenge posed to society to come to grips with the problem of man-made climate ...
Asymptotic behavior of cosmological models in scalar-tensor theories of gravity
(1999-01)

Self-assembly of novel trimers using dipyrromethene ligands
(1999-04)
Ligands comprising two dipyrromethene units linked at the beta-position have been used to
prepare trimeric complexes with Zn-II and Co-II; the structure of the Zn-II complex is confirmed by
X-ray analysis.

Why is there no low-temperature phase transition in NaOH?
(1999-02)
Although NaOH and NaOD exhibit parallel polymorphism at high temperatures, NaOD exhibits a
low-temperature phase transition to a hydrogen-bonded antiferroelectric phase and no comparable
transition has been found in NaOH. ...
