The European sTANDEM project for certification in medical English: standards, acceptability and transgression(s)
2014
In the global world of international communication, employers or institutions that wish to determine the language skills of non-native speakers of English usually turn to generalist proficiency tests such as the TOEFL (Test of English as a Foreign Language) or the slightly more business-oriented TOEIC (Test of English for International Communication). These tests enable test takers to certify that they have reached a certain level in skills needed in everyday life and, sometimes, workplace situations, but they do not assess language skills for specific purposes.Aware of this vacuum, a consortium of European teachers/researchers and international experts in the domain of medical English unde…
Sponge aggregation factor: identification of the specific collagen-binding site by means of a monoclonal antibody.
1988
The aggregation factor (AF) from the sponge Geodia cydonium is known to be a complex proteinaceous particle, composed of a series of different (glyco)proteins (Mr lower than 150,000) around a 90S sunburst-like core structure. One of the low-Mr proteins is the 47-KD cell binding fragment. We describe a new monoclonal antibody (mAb), III1E6, raised against purified AF particles, which recognizes in tissue slices structures present both on the plasma membrane and in a network-like manner in the extracellular space. By applying immunoelectron microscopical, immunoblotting, and immunoaffinity chromatographical techniques, the mAb III1E6 was shown to recognize the core structure of the AF partic…
Crystal structure of the chalcone (E)-3-(furan-2-yl)-1-phenylprop-2-en-1-one
2015
The crystal packing of the compound is described by an intermolecular arrangement with the molecules as interlaced layers in a zigzag fashion, denoting interacting self-complementary dimers mainly by the localization of weak hydrogen bonds in a head-to-tail arrangement.
Impact of O → S Exchange in Ferrocenyl Amides on the Structure and Redox Chemistry
2014
The conformations and redox chemistry of ferrocenyl amides have been investigated in considerable depth in the last few years, while ferrocenyl thioamides have attracted less interest so far, although distinctly different conformations and reactivity patterns are expected. Monoferrocenyl amides Fc-NHC(O)CH3 (1) and 1,1′-CH3O(O)C-Fn-NHC(O)CH3 (2) and diferrocenyl amides Fc-NHC(O)-Fc (5) and Fc-NHC(O)-Fn-NHC(O)CH3 (6) are easily transformed into the corresponding thioamides (3, 4, 7, 8) by treatment with Lawesson’s reagent (2,4-bis(p-methoxyphenyl)-1,3-dithiaphosphetane-2,4-disulfide) (Fc = Fe(C5H4)(C5H5), Fn = Fe(C5H4)2). The thioamide conformations (cis/trans) in 3, 4, 7, and 8 and the hydr…
The Role of Planarity versus Nonplanarity in the Electronic Communication of TCAQ-Based Push–Pull Chromophores
2018
Donor-acceptor-substituted alkynes, endowed with 11,11,12,12-tetracyano-9,10-anthraquinodimethane (TCAQ) and N,N-dimethylaniline (DMA) units, have been further functionalized by a [2+2] cycloaddition with tetracyanoethylene (TCNE) followed by a subsequent retro-electrocyclization to form distorted nonplanar structures with bridging 1,1,4,4-tetracyanobuta-1,3-diene (TCBD) units. Comprehensive spectroscopic, electrochemical, and computational studies have been carried out to compare the electronic communication in planar (alkyne bridges) and nonplanar (TCBD bridges) TCAQ-based push-pull chromophores. Cyclic voltammetry and UV/Vis absorption measurements confirm the electronic communication be…
Crystal structure of 2-methyl-1H-imidazol-3-ium aquatrichlorido(oxalato-κ2O,O′)stannate(IV)
2015
N—H⋯O, N—H⋯Cl and O—H⋯O hydrogen bonds between cations and anions in the complex salt (C4H7N2)+[Sn(H2O)Cl3(C2O4)]− are responsible for the formation of a three-dimensional network structure.

Synthesis, crystallographic and electrochemical study of ethynyl[2.2]paracyclophane derived cobalt metallatetrahedranes
2012
Abstract A series of alkynyl cobalt complexes [Co2(μ-η2-HCC–PCP)(CO)6−nLn] [n = 0 (2); n = 2, L2 = dppa (3), dppm (4), dcpm (6), 2 P(OPh)3 (7)] and [Co2(CO)4L2]2(μ-η2:μ-η2-HCC–PCP–CCH)] (L2 = dppm (8), dcpm (9); (PCP = [2.2]paracyclophane) has been prepared and characterized. The molecular structures of 3 and 4, as well as that of [Co2(CO)4(μ-CO)2(μ2-dcpm)] (5), have been determined by X-ray diffraction. Electrochemical studies (Cyclic Voltammetry, Rotating Disk Electrode) and luminescence spectroscopy have been used to evaluate the extent of the electronic communication through the PCP motif using the “Co2C2” centres as a probe. No electronic coupling between the Co2(CO)n centres via the b…
A Functional Analysis of the Finnish 2012 Presidential Elections
2016
This study applied the functional theory of political campaign discourse, developed for political campaigns in the United States to two televised presidential debates in the 2012 presidential elections in Finland. Acclaims were the most preferred statement by the candidates, with agreements being the least preferred. Policy was discussed more than character during the debates. General goals and ideals were used more frequently to acclaim than to attack. Results are generally consistent with the results of previous studies of presidential elections in the US and other countries. However, differences did emerge: the classical functional categories were supplemented by a new category, the role…
Communication role on perception and beliefs of EU citizens about science
2020
Este documento presenta un conjunto de recomendaciones basadas en el conocimiento de las consultas públicas de CONCISE. Los puntos se enumeran según los diferentes destinatarios: comunicadores científicos, responsables políticos, científicos y público en general. El principal objetivo de CONCISE es determinar el papel que desempeña la comunicación científica en la formación de creencias, percepciones y conocimientos sobre cuestiones científicas. Para lograr este objetivo, CONCISE llevó a cabo cinco consultas públicas en Lisboa (Portugal), Valencia (España), Vicenza (Italia), Trnava (Eslovaquia) y Lodz (Polonia) con la participación de cerca de 500 ciudadanos. Esto permitió al consorcio reco…
