TL;DR: In this paper, the hydrogen evolution reaction (HER) on RuO2 coated nickel electrodes was investigated by d.c. polarization studies and impedance measurements in alkaline solution and the rate constants of the forward and backward reactions of these two two steps were estimated by a nonlinear fitting procedure.
Abstract: The hydrogen evolution reaction (HER) on RuO2 coated nickel electrodes was investigated by d.c. polarization studies and a.c. impedance measurements in alkaline solution. The electroactive RuO2 coatings were prepared by thermal decomposition of a RuCl3 solution at 450°C in air. The real surface area of the cathodes was estimated from cyclic voltammetric measurements and from the double layer capacitance (evaluated by impedance measurements). A mechanism for the HER has been proposed involving two steps (Volmer and Heyrovsky reactions). The rate constants of the forward and backward reactions of these two steps have been estimated by a nonlinear fitting procedure.

TL;DR: It is concluded that fermented foods are still important sources of new functional LAB, and the bacteriocin-producing strains isolated in this study may find applications as protective cultures.
Abstract: Lactic acid bacteria (LAB) isolated from different sources (dairy products, fruits, fresh and fermented vegetables, fermented cereals) were screened for antimicrobial activity against other bacteria, including potential pathogens and food spoiling bacteria. Six strains have been shown to produce bacteriocins: Lactococcus lactis 19.3, Lactobacillus plantarum 26.1, Enterococcus durans 41.2, isolated from dairy products and Lactobacillus amylolyticus P40 and P50, and Lactobacillus oris P49, isolated from bors. Among the six bacteriocins, there were both heat stable, low molecular mass polypeptides, with a broad inhibitory spectrum, probably belonging to class II bacteriocins, and heat labile, high molecular mass proteins, with a very narrow inhibitory spectrum, most probably belonging to class III bacteriocins. A synergistic effect of some bacteriocins mixtures was observed. We can conclude that fermented foods are still important sources of new functional LAB. Among the six characterized bacteriocins, there might be some novel compounds with interesting features. Moreover, the bacteriocin-producing strains isolated in our study may find applications as protective cultures.

TL;DR: In this paper, the generalized Carleson operator with polynomial phase function of degree two is shown to be of weak type (2,2) and a new approach to the time-frequency analysis of the quadratic phase is introduced.
Abstract: We prove that the generalized Carleson operator with polynomial phase function of degree two is of weak type (2,2). For this, we introduce a new approach to the time-frequency analysis of the quadratic phase.
