Pyrosequencing vs. culture-dependent approaches to analyze lactic acid bacteria associated to chicha, a traditional maize-based fermented beverage fr…
2015
The diversity of lactic acid bacteria (LAB) associated with chicha, a traditional maize-based fermented alcoholicbeverage from Northwestern Argentina, was analyzed using culture-dependent and culture-independent approaches.Samples corresponding to 10 production steps were obtained from two local producers at Maimará(chicha M) and Tumbaya (chicha T). Whereas by culture-dependent approach a few number of species(Lactobacillus plantarum and Weissella viridescens in chicha M, and Enterococcus faecium and Leuconostocmesenteroides in chicha T) were identified, a higher quantitative distribution of taxa was found in both beveragesby pyrosequencing. The relative abundance of OTUs was higher in chic…
Angst und Verzagtheit im . Eine Studie zum Wortschatz der Angst
2015
The Meier Helmbrecht, written by Wernher der Gärtner between 1250 and 1280, has often been object of study especially with regard to the protagonist’s extreme ambition and the disowning of his own origins and of his family heritage, but it also offers excellent opportunities for linguistic reflexions. Contrary to what is expected in a text, where the main character lives an immoral life and where his family is constantly concerned about his fate, there are few words to express fear or anxiety, but Wernher der Gärtner chooses the words used carefully, highlighting the different ways the characters perceive and reveal these emotions. The study of the vocabulary of fear in this work allows us …
The formal redox potential of the Yb(III,II) Couple at 0°C in 3.22 molal NaCl medium
2004
Following our previous investigations on aqueous solutions of hypooxidized and iperoxidized species, we managed, by lowering the temperature of the solutions to 0 degrees C, to obtain, by electrochemical methods, Yb(II) and Yb(III) mixtures, enough stable to determine by a potentiometric method the formal redox potential of the Yb(IlI, II) couple. Its value, in a large range of total Ytterbium concentration, is -1233 +/- 3 mV against the molal hydrogen electrode in the 3.22 m NaCl medium.
Complexes of titanium and zirconium containing a tridentate linked amido–cyclopentadienyl ligand with a soft donor group: synthesis, structure, and e…
1999
Abstract Group 4 metal complexes M(η5:η1-C5R4SiMe2NCH2CH2SMe)Cl2 (R=H, M=Ti; R=Me, M=Ti, Zr) containing the thioether-functionalized linked amido–cyclopentadienyl ligand were synthesized and characterized by 1H- and 13C-NMR spectroscopy, mass spectrometry, and elemental analysis. The crystal structures of the complexes Ti(η5:η1-C5H4SiMe2NCH2CH2SMe)Cl2 and Zr(η5:η1:η1-C5Me4SiMe2NCH2CH2SMe)Cl2 were determined by single-crystal X-ray diffraction studies. The titanium complex is a conventional three-legged piano-stool molecule without an intramolecular interaction between the sulfur donor group and the titanium center, whereas the zirconium complex adopts a trigonal bipyramidal structure, with …
Ethylene polymerization with FI complexes having novel phenoxy-imine ligands: Effect of metal type and complex immobilization
2011
A series of bis(phenoxy-imine) vanadium and zirconium complexes with different types of R3 substituents at the nitrogen atom, where R3 = phenyl, naphthyl, or anthryl, was synthesized and investigated in ethylene polymerization. Moreover, the catalytic performance was verified for three supported catalysts, which had been obtained by immobilization of bis[N-(salicylidene)-1-naphthylaminato]M(IV) dichloride complexes (M = V, Zr, or Ti) on the magnesium carrier MgCl2(THF)2/Et2AlCl. Catalytic performance of both supported and homogeneous catalysts was verified in conjunction with methylaluminoxane (MAO) or with alkylaluminium compounds (EtnAlCl3−n, n = 1–3). The activity of FI vanadium and zirc…

A “participação africana” num desporto olímpico: Lutas espaciais e questões de nacionalidade
2016
Cet article analyse les stratégies de reconnaissance d’une discipline olympique : le canoë de slalom. Il interroge en particulier les processus de diffusion de ce sport en Afrique en étudiant précisément sa place en tant que discipline au sein du mouvement olympique. Mais comment la diffusion d’un sport parmi les pays africains peut-elle cristalliser des enjeux nationaux ? Pour comprendre la complexité de cet objet, le remaniement des aires culturelles issues du joug des empires coloniaux est interrogé. Il s’agit d’inscrire les perceptions de la participation olympique dans les rivalités où elles s’inscrivent depuis les Indépendances. L’enquête restitue l’apport de la nationalité comme crit…
Queratoconjuntivitis epidémicas en el trabajo. Reflexiones en torno a su manejo y catalogación
2019
Introducción: las conjuntivitis epidémicas presentan alto riesgo de contagio. Pueden tener etiología laboral. Objetivos: conocer datos epidemiológicos y cuantificar costes económicos; aportar información sobre manejo y catalogación. Material / Métodos: estudio descriptivo-retrospectivo de una serie de casos (contingencias profesionales) por conjuntivitis epidémica (CIE-9) durante 2014-2015 en FREMAP, que generaron procesos de incapacidad temporal. Resultados: sobre el total de patologías oftalmológicas laborales con baja, representaron el 1,6%. Mujeres 75%, sector servicios y 39 años de media. Bilateral 73% de los casos. El 46% recibió asistencia previa. Tratamiento médico 86,48% (colirios …
