The level of context dependence of engagement markers in Peninsular Spanish and US business websites
2019
This paper examines the impact of Spaniards’ and North-Americans’ level of context dependence (Hall, 1976) on the engagement markers (Hyland & Tse, 2004) used on the presentation page of 100 business websites from the toy sector (50 from Spain and 50 from the US). Following an observational and a quantitative analysis, the findings reveal remarkable statistical differences in the interactional discourse of this digital genre, which may be a valuable source of information for export companies to introduce their products abroad by means of their business websites. In addition, we believe that the business website can be used in the teaching and learning of Spanish and English for professional…
First-year engineering students’ use of their mathematics textbook - opportunities and constraints
2012
Published version of an article in the journal: Mathematics Education Research Journal. Also available from the publlisher at: http://dx.doi.org/10.1007/s13394-012-0040-9 The role of the mathematics textbook at tertiary level has received limited exposure in previous research although it is likely that students work individually and that some of this work depends on the use of the textbook. The aim of this study was to investigate the process of approaching the textbook from epistemological, cognitive, and didactical perspectives. The focus was on identifying and discussing the opportunities and constraints in the process. The study was an explorative case study and the participants were fi…
El tratamiento integrado de lenguas en la gramática: una aproximación a la terminología básica en los libros de texto de secundaria
2021
Este artículo analiza la variación terminológica que afecta las denominaciones (variación denominativa), porque en muchas ocasiones los términos constituyen un obstáculo en la construcción de los conceptos. Concretamente, se ha desarrollado un trabajo terminográfico, de recopilación de los términos utilizados para referirse a las diferentes clases de palabras en los libros de texto de las asignaturas de Castellano y Valenciano de primero y segundo de ESO. Los resultados obtenidos muestran la gran incoherencia terminológica de los libros de texto, con un exceso de términos que dificultan el aprendizaje del alumnado, lo que pone de manifiesto la necesidad de llevar a cabo un tratamiento integ…
Candida antarctica Lipase A-Based Enantiorecognition of a Highly Strained 4-Dibenzocyclooctynol (DIBO) Used for PET Imaging
2020
The enantiomers of aromatic 4-dibenzocyclooctynol (DIBO), used for radiolabeling and subsequent conjugation of biomolecules to form radioligands for positron emission tomography (PET), were separated by kinetic resolution using lipase A from Candida antarctica (CAL-A). In optimized conditions, (R)-DIBO [(R)-1, ee 95%] and its acetylated (S)-ester [(S)-2, ee 96%] were isolated. In silico docking results explained the ability of CAL-A to differentiate the enantiomers of DIBO and to accommodate various acyl donors. Anhydrous MgCl2 was used for binding water from the reaction medium and, thus, for obtaining higher conversion by preventing hydrolysis of the product (S)-2 into the starting materi…

Control of Growth and Persistence of Listeria monocytogenes and β-Lactam-Resistant Escherichia coli by Thymol in Food Processing Settings
2020
The main objective of this study was to evaluate the efficacy of thymol in controlling environmental contamination in food processing facilities. The effect of thymol was tested as an agent to prevent planktonic and bacterial biofilm growth of twenty-five Listeria monocytogenes isolates from a variety of foods and five Escherichia coli isolates from a farm. The E. coli isolates were positive for extended spectrum &beta

La fauna del pleistoceno inferior de la Sierra de Quibas (Abanilla, Murcia)
1999
El yacimiento kárstico cuaternario de la Sierra de Quibas (Abanilla, Murcia) ha proporcionado una amplia lista faunística constituida por 53 especies repartidas entre gasterópodos, miriápodos, anfibios, reptiles, aves y mamíferos. En el conjunto de los gasterópodos destaca Palaeoglandina, un género que se extingue en el resto de Europa durante el Plioceno y que se mantiene como relicto en el Pleistoceno de la Península Ibérica. Dos de las especies de aves determinadas, Gypaetus barbatus y Gerontieus eremita, y una de las serpientes, Elaphe cf. E. sealaris, apenas se hallan representadas en el registro fósil. Hay además varias especies de aves cuya aparición en Quibas supone la primera cita …

Aging of the musculoskeletal system: How the loss of estrogen impacts muscle strength.
2019
Skeletal muscle weakness occurs with aging and in females this is compounded by the loss of estrogen with ovarian failure. Estrogen deficiency mediates decrements in muscle strength from both inadequate preservation of skeletal muscle mass and decrements in the quality of the remaining skeletal muscle. Processes and components of skeletal muscle that are affected by estrogens are beginning to be identified. This review focuses on mechanisms that contribute to the loss of muscle force generation when estrogen is low in females, and conversely the maintenance of strength by estrogen. Evidence is accumulating that estrogen deficiency induces apoptosis in skeletal muscle contributing to loss of…
