This paper outlines the functionality and application of video conferencing in relation to relevant learning theories. It also explores the strengths and weaknesses that might be created by this technology. The outcomes of a trial undertaken at the University of Oxford during a group project also provides the basis for predicting the usefulness of the technology for learner-centred interactions...

Multimodal communication is ubiquitous in nature. Plants lure pollinators with colour and fragrance, animals combine sounds visual displays during courtship humans gesture while talking (Fröhlich & van Schaik, 2018; Halfwerk et al., 2019; Higham Hebets, 2013; Munoz Blumstein, 2020; Partan Marler, 1999; Ullrich 2016). These multimodal presumably evolved to increase signal salience, aid species r...

It becomes possible now to detect cold molecules at high redshift in the millimeter domain. Since the first discovery in 1992 by Brown and van den Bout of CO lines at z = 2.28 in a gravitationally lensed starburst galaxy, nearly ten objects are now known to possess large quantities of molecular gas beyond z = 1 and up to z ∼ 5, through millimeter and sub-millimeter emission lines. Even more obj...

The transmission of power using light instead electricity—the so called power-by-light (PBL)—has been around for some decades now. Despite this long history, it has only in recent years when PBL systems have experienced enormous effervescence situations where the direct use electrical energy to electronic equipment is either not possible or recommendable. are smarter solution monitoring and con...

The redshifted spectral line radiation emitted from both atomic fine-structure and molecular rotational transitions in the interstellar medium (ISM) of high-redshift galaxies can be detected in the centimetre, millimetre and submillimetre wavebands. Here we predict the counts of galaxies detectable in an array of molecular and atomic lines. This calculation requires a reasonable knowledge of bo...
