The external didactic transposition of mathematics at university level: dilemmas and challenges
(Pontifícia Universidade Católica de São Paulo, 2020)
We develop the idea that research on university mathematics education needs to more systematically address the external didactic transposition. After outlining existing research that goes more or less ...
Development of green/red-absorbing chromophores based on a coumarin scaffold that are useful as caging groups
(American Chemical Society, 2017-05)
We report the design, synthesis, and spectroscopic characterization of a series of push–pull chromophores based on a novel coumarin scaffold in which the carbonyl of the lactone function of the original ...
Computational analysis of polymer molecular structure effect on nanocavities replication via injection moulding
(Asociación de Químicos e Ingenieros del Instituto Químico de Sarrià, 2018-01)
The purpose of this work is to study how the molecular structure of a polymer affects the replication of nanocavities when injection moulding manufacturing process is used. Even though the process and ...
Audit partner tenure and independence in a low litigation risk setting
(Taylor & Francis, 2016-10)
We investigate whether long audit partner tenures impair auditor independence, as proxied by the opinion of the audit report, with a sample of Spanish companies for the period: 2002–2010. The Spanish ...

El análisis frecuencial de sistemas de control se basa en el conjunto de respuestas del proceso a señales senoidales que, en la mayoría de casos de los procesos habituales en la industria química, han ...
Simulaciones para aprender sobre el enlace, la geometría de las moléculas y la estructura de las sustancias
(Graó, 2016)
Las herramientas de modelización molecular son de uso común en investigación ypermiten explorar las estructuras de las entidades químicas y predecir las propiedades de las mismas. Del mismo modo, estos ...
Ex-dividend day returns when dividend and capital gains are taxed at the same rate
(Charles University, 2011-08)
Due to the overwhelming international evidence that stock prices drop by less than the dividend paid on ex-dividend days, the ex-dividend day anomaly is considered a stylized fact. Two main approaches ...
Chelating properties of tripeptide-9 citrulline
(Asociación de Químicos e Ingenieros del Instituto Químico de Sarrià, 2012-10)
Tripeptide-9 Citrulline (INCI name) is a peptide with skin care properties, used for cosmetic applications. In order to elucidate its mechanism of action in the chemical pathways that involve metal ions, ...
