Low-dimensional copper(II) complexes with the trinucleating ligand 2,4,6-tris(di-2-pyridylamine)-1,3,5-triazine: synthesis, crystal structures, and m…
2010
The preparation and structural characterization of three new copper(II) complexes of formula [Cu(3)(dipyatriz)(2)(H(2)O)(3)](ClO(4))(6) x 2 H(2)O (1), {[Cu(4)(dipyatriz)(2)(H(2)O)(2)(NO(3))(2)(ox)(2)](NO(3))(2) x 2 H(2)O}(n) (2), and [Cu(6)(dipyatriz)(2)(H(2)O)(9)(NO(3))(3)(ox)(3)](NO(3))(3) x 4 H(2)O (3) [dipyatriz = 2,4,6-tris(di-2-pyridylamine)-1,3,5-triazine and ox = oxalate] are reported. The structure of 1 consists of trinuclear units [Cu(3)(dipyatriz)(2)(H(2)O)(3)](6+) and uncoordinated perchlorate anions. The two dipyatriz molecules in 1 act as tris-bidentate ligands with the triazine cores being in a quasi eclipsed conformation. Each copper atom in 1 exhibits a distorted square pyr…

Metropolitan wastewater analysis for COVID-19 epidemiological surveillance
2020
The COVID-19 disease, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a rapidly emerging pandemic which has enforced extreme containment measures worldwide. In the absence of a vaccine or efficient treatment, cost-effective epidemiological surveillance strategies are urgently needed. Here, we have used RT-qPCR for SARS-CoV-2 detection in a series of longitudinal metropolitan wastewaters samples collected from February to April 2020, during the earliest stages of the epidemic in the Region of Valencia, Spain. We were able to consistently detect SARS-CoV-2 RNA in samples taken in late February, when communicated cases in that region were only incipient. We also find…
Achieving Bologna Goals: Where Does Europe Stand Ahead of 2010
2010
Ten years have passed since the signature of the Bologna declaration. Seventeen countries have joined the process; since then, several new action lines have been added and the original action lines have often gained a new and more sophisticated content. The 2009 Bologna Stocktaking exercise included the traditional quantitative indicators, the criteria this time being designed to evaluate the goals set for 2010. In addition, particular emphasis was put on qualitative analysis on this occasion to provide a realistic picture of what has been achieved and which initiatives will take more time than anticipated to implement. The 2009 stocktaking shows that while there has indeed been important …
Life cycle assessment of low temperature asphalt mixtures for road pavement surfaces: A comparative analysis
2018
The increasing fuel consumption demand, the accelerated pressure imposed by the depletion of 5 scarce raw materials and the urgent environmental protection requirements are forcing the change of 6 pavement industry and academia community’s research endeavors towards the development of low 7 emissions road paving technologies able to significantly reduce mixing and compaction temperature as 8 well as the consumption of virgin raw materials. One set of relatively recent technologies in the field of 9 pavement materials that aims at addressing those concerns are the warm mix asphalt (WMA). In fact, 10 they have the potential to allow the reduction of energy consumption and airborne emissions d…
Successful turnarounds in bankrupt firms? Assessing retrenchment in the most severe form of crisis
2019
During economic downturns, firms file for bankruptcy in an effort to attempt a “turnaround.” The objective of this study is to assess the effectiveness of retrenchment strategies in the context of bankruptcy, as the most severe form of crisis. We conducted a longitudinal analysis of a sample of 868 bankrupt Spanish firms during the period 2004–2017. The empirical results show that stakeholder support and deep cost retrenchment increase the likelihood of survival and performance recovery, while aggressive layoffs are detrimental for turning bankrupt firms around. Surprisingly, intense asset retrenchment had no significant effects on firm survival and also pushed performance downward. The fi…
Utilidad pública de las asociaciones. Revocación por la Administración y solución fundacional.
2019
La finalidad no lucrativa de las asociaciones puede encaminarse a la consecución de fines tanto de interés particular como de interés general. En este segundo caso, la búsqueda del bien común les hace merecedoras de una especial protección por parte de los poderes públicos que se concreta en su declaración legal como «asociaciones de utilidad pública». Sin embargo, tras la Ley Orgánica de Asociaciones, de 22 de marzo de 2002 (LODA), la administración se muestra renuente a otorgar la calificación de utilidad pública a aquellas asociaciones que, en aras a allegar recursos para el cumplimiento de sus fines, desarrollen una actividad económica. A resultas de dicho proceder administrativo estas …
Trends Regarding the Evolution of the Romanian Pension System
2018
Abstract The pension system, together with the social assistance services form the social security system is recognized worldwide throughout the adoption of the Universal Declaration of Human Rights for the purpose of insured person compensation for damages regarding some inherent risks as: permanent or temporary inability of work, old age or unemployment. The main objectives of a pension system are decreasing poverty regarding the lower income persons throughout the conditions of limitation of the working capacity which are financially vulnerable. In this article we provide a qualitative and quantitative overview regarding the Romanian pension system structure and mechanism. The conclusion…
Microscopical and Mycological Investigations on Wood of Pendunculate Oak (Quercus robur L) Relative to the Occurrence of Oak Decline
1996
Summary Microscopical studies exhibited great differences between healthy and damaged pendunculate oak trees (Quercus robur L.) relative to the state of sapwood vessels and the degree of fungal infection. In the sapwood of damaged trees deposits, discolorations and early tylosis formations were found which frequently occurred in combination with fungal infections. These results lead to the assumption that the defence reaction of the trees probably induced by fungal infection changes the structure of the tree vessels to such an extent that their water transfer function is disturbed. Some fungal genera playing an important role in the discussion of the causes of oak decline could be isolated.…
