The stimulating effect of 1-alkyl-1-ethyl piperidinium bromides on the oxygen evolution rate in spinách chloroplasts was caused by rearrangement of thylakoid membrane.
Assuming tho exlstence of organised photospheric velocltly tlelds In an actlve region, we study the creatlon of photospherIc and coronal D.C. currents by vortex rriotlons. Vortex motions leading to opposlte
temporal evolutions of the magnetic flux In old and new centres of activlty create two systems of coronal currents flowlng along the lines of force which, In the active region complex, connect tbe old centre of activlty to the new. The magnetic energy stored In these currents Is hlgher than the energy of the largest flares. The two systems of coronal currents are inside two dlfferent magnetic cells. They Interact along the separator which Is tho Intersectlon of the magnetlc llne surfaces that separate the magnetic cells produced by the photospheric magnetic sourcos. Due to sourco motlons and electrlc current evolutlon, the separator may bo the location of reconnection of the magnetlc fleld. This reconnectlon wouid affect the magnetic fleid of tho various loops of the two current systems and couid lead to an interruption of the currents that wouid release qulckly the stored magnetlc energy. The separator crossing the two current systems, these intabilities couid affect all the loops and produce ribbon flares.
Here we present some interesting aspects of interplay between quantum theory and functional analysis. We show that some of the deepest problems in both disciplines are unexpectedly equivalent. Starting from a historical point of view we comment on the following topics: connection between the structure of von Neumann algebras and the structure of quantum theories, construction of quantum integral and logic of quantum systems, Bell inequalities in light of Grothendieck inequality and operator space theory. Finally, we discuss bohrification and topos approach to quantum theory., Martin Bohata, Jan Hamhalter., and Obsahuje bibliografii
The thermoluminescence signals from leaflets of the same pea plant varied gradually according to their developmental stage. The AG emission, due to a back flow of electrons towards photosystem 2 (PS2) along a cyclic/chlororespiratory pathway, was stronger in mature leaves than in the growing ones. These age-related variations could be explained by a higher capacity of cyclic electron flow in mature leaves.
