    The industrial district of Castellon is characterized by a great dynamism based on technological innovation, both product and process, the origins of which are to be found on its providers (1), the machinery industry and the frit, glaze and colours industry. In this paper the current situation of the frit, glaze and colour industry is analyzed, accounting also for the situation of its main European competitor in Italy. The formation and development of the industry is also described in relation to the industrial district and the innovation system where it belongs, together with the R&D activity, the innovation activity, and the main technological milestones that have made it become the world leader. The analysis shows the challenges to which this subsector, and more generally, the tile innovation system need to react to, by means of cooperation, in order to maintain the tile district leadership. Globalization implies new behaviours and one of the most relevant is the increase of cooperation among the different actors in the innovation system

    Enantio- and diastereocontrol in intermolecular cyclopropanation reaction of styrene catalyzed by dirhodium(II) complexes with bulky ortho-metalated aryl phosphines

    Get PDF
    Enantiomerically pure dirhodium(II) complexes with ortho-metalated p-substituted aryl phosphines have been shown to be enantio- and diastereoselective in the cyclopropanation of styrene by ethyl diazoacetate. Enantioselectivities up to 91% and diastereoselectivities up to 90% are observed for ethyl cis-2-phenylcyclopropanecarboxylate.Estevan Estevan, Francisco, [email protected] ; Lahuerta Peña, Pascual, [email protected] ; Lloret Fillol, Julio, [email protected] ; Sanau Torrecilla, Mercedes, [email protected] ; Ubeda Picot, M Angeles, [email protected] ; Vila Gomez, Jaume Llorenc, [email protected]

    Este trabalho tem por objetivo apresentar um estudo sobre os efeitos causados pela variação na quantidade de sub-portadoras piloto transmitidas no processo de estimação da resposta em frequência do canal de comunicação e no processo de equalização e detecção coerente dos símbolos transmitidos em receptores de sistemas OFDM. Para tal investigação serão propostos dois diferentes cenários de simulação numérica através da ferramenta computacional MATLAB®. Serão apresentadas análises qualitativas e quantitativas através de gráficos e cálculos matemáticos

    La autoeficacia física percibida y el rendimiento deportivo en taekwondo

    Get PDF
    En el contexto físico-­‐deportivo una de las variables de mayor interés tanto para entrenadores, deportistas como para el público en general es el rendimiento deportivo. Actualmente se tiende a identificar características o habilidades psicológicas que pueden estar interviniendo en dicho rendimiento. Una de las variables psicológicas más estudiadas, en los últimos años, en relación con el rendimiento deportivo es la auto-­‐confianza en las propias capacidades físicas

    How do disadvantaged groups perceive allies? Women’s perceptions of men who confront sexism in an egalitarian or paternalistic way

    Get PDF
    In this research, we focused on women's perception of men as allies depending on the type of confrontation. We conducted four experimental scenario studies (Study 1 and 2 in a bar setting; Study 3 and 4 in a workplace setting) where a man confronted a sexist comment using either an egalitarian or paternalistic argument. Results showed that women are more likely to perceive egalitarian (vs. paternalistic) confronters as allies (Studies 1–4). This is explained by the fact that they contribute to reducing power asymmetries (decreasing perceived interpersonal power differences: Studies 2 and 4; or increasing women's empowerment: Studies 3 and 4). Furthermore, the egalitarian (vs. paternalistic) confrontation positively impacts interpersonal and intergroup relations, and this is explained by the perception of the confronter as an ally (Studies 1, 2 and 4). We discuss the role of disadvantaged group members’ perception of advantaged group members to disentangle the complexity of alliances.Spanish Ministry of Science and Innovation, Grant/Award Numbers: FPU14/0511, PID2019-111549GB-I00, MCIN/AEI/10.13039/501100011033Universidad de Granada/CBU

    Unique Features of Alarmone Metabolism in \u3ci\u3eClostridioides difficile\u3c/i\u3e

    Get PDF
    The “magic spot” alarmones (pp)pGpp, previously implicated in Clostridioides difficile antibiotic survival, are synthesized by the RelA-SpoT homolog (RSH) of C. difficile (RSHCd) and RelQCd. These enzymes are transcriptionally activated by diverse environmental stresses. RSHCd has previously been reported to synthesize ppGpp, but in this study, we found that both clostridial enzymes exclusively synthesize pGpp. While direct synthesis of pGpp from a GMP substrate, and (p)ppGpp hydrolysis into pGpp by NUDIX hydrolases, have previously been reported, there is no precedent for a bacterium synthesizing pGpp exclusively. Hydrolysis of the 5′ phosphate or pyrophosphate from GDP or GTP substrates is necessary for activity by the clostridial enzymes, neither of which can utilize GMP as a substrate. Both enzymes are remarkably insensitive to the size of their metal ion cofactor, tolerating a broad array of metals that do not allow activity in (pp)pGpp synthetases from other organisms. It is clear that while C. difficile utilizes alarmone signaling, its mechanisms of alarmone synthesis are not directly homologous to those in more completely characterized organisms
