eTwinning Collaborative Learning Environment in Initial Teacher Education

2018

This paper aims to describe the eTwinning Teacher Training Institutes Pilot (TTI)1experiment during academic year 2014/15 with 550 undergraduate students from first and second year of Educational Technologies degree courses. The research was given start with the purpose of preparing tomorrow's teachers for a future where the use of ICT and is in everyday teaching, to promote their digital skills and communication skills, and their use of English as a foreign language within a cross-cultural context. The teaching presence was proved through proper supervision and the emergence of mutual support from 36 tutors and 550 students. The results of the research contributed to our understanding of h…

Influence of twinned structure on the morphology of CdTe(111) layers grown by MOCVD on GaAs(100) substrates

2003

Abstract The morphology and structure of CdTe(1 1 1) layers grown on GaAs(1 0 0) by MOCVD have been studied by atomic force microscopy (AFM) and X-ray texture analysis. Growth conditions have been chosen so that mirror-like CdTe layers are obtained. Layers whose growth times vary between 10 s and 2 h have been investigated. The X-ray texture analysis shows that the CdTe layers grown on GaAs substrates that were thermally treated at 580°C for 30 min in a H 2 atmosphere exhibit a (1 1 1) preferential orientation and are twinned. This twinned structure of the (1 1 1)CdTe layer which is observed as 60° rotated triangular crystallites in the AFM images strongly influences the surface morphology.…

Structural characterization of CdTe layers grown on (0001) sapphire by MOCVD

2004

Abstract We report on the growth of CdTe layers directly onto (0 0 0 1) sapphire substrates by MOCVD. The structure and morphology of the layers have been investigated as a function of growth temperature and II/VI precursor molar ratio by X-ray diffraction and scanning electron microscopy. The texture of the samples has revealed the existence of a temperature threshold, with higher growth temperatures resulting on completely (1 1 1) oriented layers. Some of these layers contained microtwins, as indicated by the extra peaks in the {4 2 2} Φ scans, leading to the existence of two different domains. The structural quality of each domain, as well as of the sample as a whole, has been determined…

creación de relatos digitales no lineales como herramienta intercultural en el ámbito de la filología francesa

2021

Este artículo aborda la importancia de la gamificación como forma de innovación docente en contextos universitarios, concretamente en la docencia de lengua y literatura francesas, para nuestro alumnado nativo digital. La creación de serious games pueden incentivarlo, generando una participación activa en la materia y mejores resultados académicos. Concretamente, la creación de ficciones interactivas basadas en hipertextos a través de una herramienta bastante novedosa llamada Twine, nos ha llevado a realizar talleres en clase de TICE en el Grado de LML de la UV con asombrosos resultados. Vamos a analizarlos y a ofrecer ejemplos didácticos para implementar esta herramienta en el aula en conte…

Early intestinal perforation secondary to congenital mesenteric defects

2016

Abstract Gastrointestinal perforation (GIP) in preterm neonates may be idiopathic, due to necrotizing enterocolitis (NEC), or mechanical obstruction. The predominant cause of GIP in the neonatal period is NEC. Differential diagnosis with congenital malformations, including mesenteric defects leading to internal hernias, is mandatory if the onset is early. We describe two newborns with trans-mesenteric herniation resulting in GIP, and we discuss the presence of possible additional risk factors such as prematurity and predisposing vascular disruption in connective tissue disorders (Ehlers-Danlos syndrome), twinning, and use of assisted reproductive technologies. These cases prompted us to rev…

Heritability of Intraocular Pressure in Older Female Twins

2006

Purpose To examine the heritability of intraocular pressure (IOP) among older women not diagnosed as having glaucoma. Design Cross-sectional twin study. Participants 94 monozygotic (MZ) and 96 dizygotic (DZ) female twin pairs aged 63–76 years and not diagnosed as having glaucoma. Methods Intraocular pressure was measured using a noncontact tonometer. The contributions of genetic and environmental factors to individual differences in IOP were estimated by applying an independent pathway model to twin data. Main Outcome Measures Contribution of genetic and environmental effects to the variation in IOP among MZ and DZ twins. Results Mean IOP of the study population was 14.1 mmHg (± standard de…

A review of the Digital Twin technology for fault detection in buildings

2022

This study aims to evaluate the utilization of technology known as Digital Twin for fault detection in buildings. The strategy consisted of studying existing applications, difficulties, and possibilities that come with it. The Digital Twin technology is one of the most intriguing newly discovered technologies rapidly evolving; however, some problems still need to be addressed. First, using Digital Twins to detect building faults to prevent future failures and cutting overall costs by improving building maintenance is still ambiguous. Second, how Digital Twin technology may be applied to discover inefficiencies inside the building to optimize energy usage is not well defined. To address thes…

Structure Monitoring with BIM and IoT: The Case Study of a Bridge Beam Model

2022

The diffusion of Building Information Modelling (BIM) as a reference methodology, applied to the world of construction, leads to important changes in the design and the management of big constructions and infrastructures. However, although the BIM approach is necessary for managing the entire life cycle of a construction, today, this methodology is still rarely adopted beyond the design phase. This represents a major flaw because the management of every phase of the life cycle of buildings needs accurate preliminary planning. Certainly, one of the most complex and important phases of the life cycle of a construction is the monitoring phase, which represents a fundamental aspect for the main…

Telomere Length in Circulating Leukocytes is Associated with Lung Function and Disease

2014

Several clinical studies suggest the involvement of premature ageing processes in chronic obstructive pulmonary disease (COPD). Using an epidemiological approach, we studied whether accelerated ageing indicated by telomere length, a marker of biological age, is associated with COPD and asthma, and whether intrinsic age-related processes contribute to the interindividual variability of lung function. Our meta-analysis of 14 studies included 934 COPD cases with 15 846 controls defined according to the Global Lungs Initiative (GLI) criteria (or 1189 COPD cases according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria), 2834 asthma cases with 28 195 controls, and s…
