In this work, we introduce a prebiotically relevant protometabolic pattern corresponding to an engine of deracemization by using an external energy source. The spontaneous formation of a nonracemic mixture of chiral compounds can be observed in out-of-equilibrium systems via a symmetry-breaking phenomenon. This observation is possible thanks to chirally selective autocatalytic reactions (Frank'...
The main aim of this study was determination of thermo- radio- and photostability ofperindopril tert-butyloamine (PER) therefore the efficiency and safety of the therapy could bemaintained.A chromatographic method (RP-HPLC) had been validated before use to determinePER loss. The evaluation of stability properties of PER in solid state under the influence ofisothermal condition, relative humidit...
During the refueling outage (RFO) 2013 at NPP Krško, electric hydrogen recombiners, a system for control during severe accidents and design basis accidents, were replaced by passive autocatalytic recombiners (PARs). next RFOs in 2015, 2016 2018, periodic tests of PAR cartridges performed. The testing NIS-PARs shall prove that catalytic reaction starts up as specified. According to licenced proc...
Recently it has been argued that autocatalytic theory could be applied to the origin of culture. Here possible application to a theory of meaning in the philosophy of language, called radical interpretation, is commented upon and compared to previous applications.
Many animal cells initiate crawling by protruding lamellipodia, consisting of a dense network of actin filaments, at their leading edge. We imaged XTC cells that exhibit flat lamellipodia on poly-L-lysine-coated coverslips. Using active contours, we tracked the leading edge and measured the total amount of F-actin by summing the pixel intensities within a 5-μm band. We observed protrusion and r...
