The aim of this work was to examine the relationship of skeletal muscle apoptosis and postmortem development of meat quality. Colour, cooking loss, myofibril fragmentation index (MFI) and shear force of duck breast and thigh meat postmortem were measured, and changes of positive nuclei were assessed with Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphophate nick end-labell...

The purpose of this article was to assess the suitability of softproofs as a surrogate for the final print in judging colourreproduction quality. A complex viewing apparatus was specially designed for this study to ensure that no cognitive cues were visible to observers and that the surround conditions for viewing softcopies and hardcopies were in very close agreement. Two experiments targeting...

A large scale psychophysical experiment was carried out to judge the perception of image quality of the photographic images. Two types of experiments, pair comparison and categorical judgment, were conducted for evaluating image difference and absolute quality respectively. Test images were generated by rendering the eight selected original images according to the change of lightness, chroma, c...

Sex, age and pre-slaughter conditioning effects on pH, temperature, colour and tenderness properties of M. semimembranosus (SM) of indigenous South African goats were investigated. Sex and age had no significant effect on pH. However, female goat carcasses cooled significantly slower than those of intact males. The carcasses of 2-teeth goats had the slowest and those of the 4–6-teeth goats the ...

Tikk, K. 2007. The influence of feeding and aging on pork quality. Doctoral thesis. ISSN 1652-6880, ISBN 978-91-576-7390-9 The objective of the present thesis was to obtain a more basic understanding on how production factors such as feeding strategies and aging of the meat influence consumerrelated pork quality attributes. Especially, post mortem colour characteristics of fresh pork and flavou...

Modern cognitive radio systems employ dynamic spectrum access techniques and these networks allow more efficient usage of scarce spectrum. Secondary users are supposed to operate in primary users’ channels without interfering them. In this paper, we propose model and analyze a channel sub-banding scheme for an opportunistic spectrum sharing system in which two secondary users are allowed to coe...

Physical, chemical and sensory changes of cut apple (cv. Jonagored) stored in the dark at 4 C were evaluated. Colour was found to be the critical parameter for this product. Apple cubes underwent severe surface browning primarily during the initial days of storage. The shelf-life of cut apple was therefore very limited, to three days maximum. Sensory analyses and objective quality evaluations o...

In this paper, an overview of Doppler ultrasound quality assurance (QA) testing will be presented in three sections. The first section will review the different Doppler ultrasound parameters recommended by professional bodies for use in QA protocols. The second section will include an evaluation and critique of the main test devices used to assess Doppler performance, while the final section of...
