The effect of natural (NE) and synthetic vitamin E supplementation (SE) on lamb meat packed under modified atmospheres (MAP) for 14 days was studied. Three hundred and sixty Rasa Aragonesa lambs were offered nine dietary treatments (0, NE125, NE250, NE500, NE1000, SE250, SE500, SE1000 and SE2000). Lambs had ad libitum access to the experimental compound feed and wheat straw, for 14 days (pre-sl...

We propose a new mechanism for diversification of male nuptial-colour patterns in the rapidly speciating cichlid fishes of Lake Victoria. Sympatric closely related species often display nuptial colours at opposite ends of the spectrum with males either blue or yellow to red. Colour polymorphisms within single populations are common too. We propose that competition between males for breeding sit...

Avian ketocarotenoid pigments occur in both the red retinal oil droplets that contribute to colour vision and bright red coloration used in signalling. Turtles are the only other tetrapods with red retinal oil droplets, and some also display red carotenoid-based coloration. Recently, the CYP2J19 gene was strongly implicated in ketocarotenoid synthesis in birds. Here, we investigate CYP2J19 evol...

Choosing a “good” set of colours for a graphical display is an important problem, but one which many data analysis practitioners are ill-equipped to solve. Most current graphics systems provide very little assistance in making good colour choices. Indeed, most systems require that a user specify their colours in ways which are closely related to the hardware representation of the colours rather...

Grapheme-colour synaesthesia is a condition characterized by atypical binding in which letters and numerals involuntarily elicit colour photisms (Ward, 2013). Previous research using transcranial magnetic stimulation (TMS) demonstrated that synaesthetes display enhanced cortical excitability selectively in primary visual cortex (Terhune, Tai, Cowey, Popescu, & Cohen Kadosh, 2011), as measured b...

Colour quantization is an established method for the reproduction of high visual quality colour imagery on systems with limited frame buffer resources. The ever increasing demand for fast and image/graphic intensive applications for cheap desktop platforms has called for greater savings in display and storage resources and simple, easy to implement architectures. Because human visual informatio...

We describe a new 28 view, 25 inch, autostereoscopic display which combines both time sequential and multi-projector technology. It is constructed from four time sequential subsystems, which abut behind a single ferroelectric liquid crystal shutter. The display has a resolution of 512×384 pixels in 24-bit colour. It allows multiple viewers to simultaneously view stereoscopic images without the ...

No evolutionary explanation for the striking colouration of coral reef fish has been established to date. Here I present the "Hyper-Visible World" hypothesis, which proposes that coral reef habitats impose special conditions on the evolution of body-colour communication for mobile fish - that is, fish that roam across coral reef formations. The special conditions are: 1) the high clarity of wat...

The use of large displays for purposes of colour communication is becoming increasingly popular and the need for high-fidelity reproduction of appearance is becoming even more demanding. In this work, the colour appearance of the ColorChecker chart was matched on a large liquid crystal display (LCD) and a comparison between the physical colours and the displayed image was made. Colour definitio...
