Collaborative virtual environments in the year of the dragon

2000

Three suggestions are made for extensions from and to CVE's: awareness of others, multiple media, and scalability. Awareness of others and their activities is strongly desirable in all media and applications, not just in CVE's. Multiple media are not seriously catered for in existing CVE's, and a suitable architecture will precede popular applications. CVE's need to be scalable to greater numbers of people, and achieving this also has implications for greater flexibility and reconfigurability. With respect to awareness of others, we argue that the Web and most document handling applications are unaware of others in the workgroup or community, and this limits the ability to support real work…

El registro fósil de vertebrados y patrimonio paleontológico más representativo de los pirineos occidentales

2019

Los Pirineos occidentales son un territorio con una notable diversidad geológica y un importante registro fósil, que constituye un gran archivo de paleobiodiversidad. En lo que respecta al registro fósil de vertebrados, los Pirineos occidentales (Región Vasco-Cantábrica, Cuenca de Pamplona y sector noroccidental de la Cuenca del Ebro) son relevantes tanto desde el punto de vista de los yacimientos paleontológicos como de las colecciones de fósiles procedentes de ellos. Varios yacimientos de vertebrados forman parte del Inventario de Lugares de Interés Geológico (LIG) con alto o muy alto interés paleontológico en la Comunidad Autónoma del País Vasco. Destacan los yacimientos de peces cretáci…

Spatial modulation of the electromagnetic energy transfer by excitation of graphene waveguide surface plasmons

2019

We theoretically study the electromagnetic energy transfer between donor and acceptor molecules near a graphene waveguide (WG). The surface plasmons (SPs) supported by the structure provide decay channels which lead to an improvement in the energy transfer rate when the donor and acceptor are localized on the same side or even on opposite sides of the WG. The modification of the energy transfer rate compared to its value in absence of the WG are calculated by deforming the integration path into a suitable path in the complex plane. Our results show that this modification is dramatically enhanced when the symmetric and antisymmetric SPs are excited. Notable effects on the spatial dependence …

Efficient Extraction of Olive Pulp and Stone Proteins by using an Enzyme-Assisted Method

2014

An efficient protein extraction protocol for proteins from olive pulp and stone by using enzymes was developed. For this purpose, different parameters that affect the extraction process, such as enzyme type and content, pH, and extraction temperature and time, were tested. The influence of these factors on protein recovery was examined using the standard Bradford assay, while the extracted proteins were characterized by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The best extraction conditions were achieved at pH 7.0 and 5% (v/v) Palatase® 20000 L (lipase) for pulp and Lecitase® Ultra (phospholipase) for stone proteins. The optimal extraction temperature and time w…

GUI Implementation of VCDtools, A Program to Analyze Computed Vibrational Circular Dichroism Spectra

2020

As computing power increases, vibrational circular dichroism (VCD) calculations on molecules of larger sizes and complexities become possible. At the same time, the spectra resulting from these computations become increasingly more cumbersome to analyze. Here, we describe the GUI implementation into the Amsterdam Density Functional (ADF) software package of VCDtools, a toolbox that provides a user-friendly means to analyze VCD spectra. Key features are the use of the generalized coupled oscillator analysis methods, as well as an easy visualization of the atomic electric and magnetic transition dipole moments which together provide detailed insight in the origin of the VCD intensity. Using s…

Transmediating argumentation : Students composing across written essays and digital videos in higher education

2016

This comparative study examined how university students built an argument in written essays and multimodal digital videos, and how their argumentation transmediated across these two mediums. Data analysis involved 1) analysis of content in both written essays and digital videos; 2) the development of transmediation visualizations to elucidate how ideas were transformed from essays into videos; and 3) multimodal analysis to understand the communicative affordances and constrains for argumentation with each medium. The findings revealed that the most common type of content in both essays and videos was supportive argumentation; however, the videos did not include any counter-argumentation. St…

Investigating the affordances of a flipped mathematics classroom from an activity theoretical perspective

2020

Abstract Flipped Classroom as a pedagogical framework has gained popularity at secondary and tertiary levels of mathematics education, but there is a lack of research based on a solid theoretical foundation. This article considers the flipped mathematics classroom from the perspective of affordances and cultural–historical activity theory. The empirical background is based on semi-structured interview data from eight first-year computer-engineering students following 1 year of flipped classroom teaching. The thematic analysis of the data indicates that the flipped format offers a range of affordances at various levels of the activity system. This article advances research on affordances for…
