El Cometa 32P [PDF]

open access: yesActes d'Història de la Ciència i de la Tècnica : IX Trobada d'Història de la Ciència i de la Tècnica : Girona, 16-19 de novembre de 2006, 2008
Josep Comas Solà, a Catalan astronomer, discovered the periodic comet 32P in 1926, this is why it’s called 32P/Comas Solà. Since then in its successive returns to the Sun it was observed before and after perihelion passage and its orbit calculated. We present a study of these results to explain the history and the evolution of this comet.

Rapid Phosphatidic Acid Accumulation in Response to Low Temperature Stress in Arabidopsis is Generated through Diacylglycerol Kinase

open access: yesFrontiers in Plant Science, 2013
Phosphatidic acid (PtdOH) is emerging as an important signalling lipid in abiotic stress responses in plants. The effect of cold stress was monitored using 32P-labelled seedlings and leaf discs of Arabidopsis thaliana.
