TL;DR: The 6-desaturation of fatty acids would be the principal regulatory step in the biosynthesis of polyunsaturated fatty acids in rat microsomes.
Abstract: The progress made in the knowledge of the microsomal fatty acid desaturation reaction is described:

TL;DR: In condiciones especiales se indujo la formación de tuberculos sin follaje a temperaturas of 20°C and 27°C as discussed by the authors.
Abstract: En condiciones especiales se indujo la formacion de tuberculos sin follaje a temperaturas de 20°C y 27°C. Despues de la brotacion se determina el estado de incubacion de los tuberculos formados a ambas temperaturas. Se concluye que la declinacion eco-fisiologica de los cultivares de papa se debe a la formacion de los tuberculos a altas temperaturas. Las temperaturas de 27°C inducen un estado de incubacion (edad fisiologica) avanzado.

TL;DR: In this article, it was shown that Schwinger and seagull terms are analytic functions of the number of dimensions of the space (v) and that the Feynman conjecture (cancellation of Schwinger terms with divergences of Seagulls) holds for arbitrary v.
TL;DR: In this article, the mean amplitudes of vibration of a series of XF6 compounds have been calculated using the "method of the characteristic vibrations" of A. Muller, and the results indicate that this method leads to very good values, also in the case of highly symmetric species.

TL;DR: The observed large E1 width of the isobaric analog state in 209Bi is found to be inconsistent with the β-decay of 210Bi as discussed by the authors, which is the first observation that the E 1 width is larger than the E 2 width.

TL;DR: In this article, the thermal and electrochemical properties of graphite in the molten alkaline nitrate have been correlated and an electrochemical reaction involving O 2 − ion and NO has been shown to proceed via an oxide on the graphite electrode surface which can be electrochemically reduced.
TL;DR: In this paper, the potentiodynamic behaviour of graphite and platinum electrodes was studied in alkaline nitrite melts, and no appreciable corrosion was observed, due to the apparently low concentration of highly oxidising species.
TL;DR: The relationship between collectivity and ground state correlations for the single closed shell lead isotopes is analyzed in this paper, under the framework of both the quasiparticle Random Phase Approximation (RPA) and Tamm-Dancoff approach.
Abstract: The relationship between collectivity and ground state correlations is analyzed for the single closed shell lead isotopes. The effects of the schematic approximation are discussed, within the framework of both the quasiparticle Random Phase Approximation and the quasiparticle Tamm-Dancoff approach. The consistency of the RPA is investigated.
TL;DR: In this paper, the influence of low Lewis number on the transient behavior of exothermic irreversible first-order catalytic reaction inside a spherical porous pellet is analyzed taking into account external heat and mass transport as well as initial conditions corresponding to a pellet at uniform temperature and devoid of reactant.
TL;DR: In this article, the authors suggest that the large difference in volume expansion for the solvated electron in ammonia and water is due to the different intermolecular interactions in both liquids.
TL;DR: In this article, the resonances in the 11-14-eV region produced in the e -H 2 interaction were suggested as mechanisms to invert the population between the upper laser states C^{1}pi and B^{1}\Sigma+u} and the ground state X^{1]-Sigma + g of the hydrogen molecule.
