Thermal degradation and isomerisation kinetics of triolein studied by infrared spectrometry and GC-MS combined with chemometrics
(Journal article; Peer reviewed, 2009)Triolein, a triglyceride containing oleic acid as the only acid moiety in the glyceride molecules has been isothermally treated at 280,300,and 325 degrees C in glass vials under nitrogen atmosphere. The products formed ... -
Effects of simulated environmental changes on growth and growth form in a late snowbed population of pohlia wahlenbergii (Web. et Mohr) Andr
(Journal article; Peer reviewed, 2003)In a factorial field experiment we increased the temperature (OpenTop Chambers) and nutrients (nitrogen, phosphorus, and potassium[NPK]) to simulate predicted future climate changes and studiedthe growth response of the ... -
Quantitative importance of staminodes for female reproductive success in Parnassia palustris under contrasting environmental conditions.
(Journal article; Peer reviewed, 2003)The five sterile stamens, or staminodes, in Parnassia palustris act both as false and as true nectaries. They attract pollinators with their conspicuous, but non-rewarding tips, and also produce nectar at the base. We ...
