Traditional views of cognition have assumed that thought involves the representation and manipulation of discrete, amodal symbols, while embodied theories of cognition hold that thought is grounded in the same neural systems that govern sensation, perception and action. This paper examines whether implicit perceptual information on object colour is represented during sentence comprehension even...

Lindahl, G. 2005. Colour characteristics of fresh pork. Doctor’s dissertation. ISSN 1652-6880, ISBN 91-576-7042-0 The objective of the present thesis was to obtain more fundamental understanding of the mechanisms for variations in colour and colour stability of fresh pork. The effects of breed and genotype, including Duroc, Hampshire (three RN alleles), Landrace and Yorkshire pigs, were studied...

Ocular prostheses have been used for centuries to restore patient confidence, psychosocial relationships and improve quality of life. Methodology producing accurate has improved with technological discoveries. Recently, hand painting ocular the go-to method creating life like prostheses. However, digital printing a print envelope around an acrylic prosthesis shown decrease treatment rehabilitat...

In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculati...

STATEMENT OF PROBLEM Acrylic teeth of dentures are prone to discoloration due to frequent exposure to different colouring solutions in the oral environment. Thus, in order to maintain their aesthetic appearance, they must possess high colour stability while exposed to colorant solutions. OBJECTIVES To compare the colour stability of three different brands of acrylic teeth following immersion ...

For dental porcelain, precise shade matching of tooth coloured restoration with the adjacent dentition is deemed necessary. However the colour instability in porcelain restoration is a common problem now a day’s particularly when they exposed to routinely consumable beverages which sever its nature of being tooth coloured. Therefore in this concern the authors has tried to emphasize the histori...

Colour is one of the most important visual attributes of food and is directly related to the perception of food quality. The interest in natural colourants, especially β-carotene that not only imparts colour but also has well-documented health benefits, has triggered the research and development of different protocols designed to entrap these hydrophobic natural molecules to improve their stabi...
