Research has been undertaken in which various methods for meat quality evaluation were compared. The measures used were pH (by homogenization and by combined electrode), light scattering conductivity, dielectric loss factor and colour. A very low incidence of PSE (Pale, Soft, Exudative) and DFD (Dark, Firm, Dry) cases was observed and the correlation(More)
Research has been conducted on objective pork quality evaluation on line in an industrial slaughterhouse. The investigation, which involved more than 5000 pigs, lasted for 12 working days spread over four consecutive weeks between October and November. Measurements performed were Fat-o-Meat'er carcass classification (lean content, fat and muscle(More)
BACKGROUND Low-intensity physiotherapeutic ultrasound has been used in physical therapy clinics; however, there remain some scientific issues regarding the bone-healing process. The objective of this study was to investigate the influence of low-intensity physiotherapeutic ultrasound on the initial stage of bone healing in rats. METHODS Twenty-two male(More)
Ultrasound parameters were proposed to characterize femur in vitro from rats. Six quantitative parameters (Apparent Integrated Ultrasonic Backscatter AIB, Frequency Slope of Apparent Backscatter – FSAB, Temporal Slope Apparent Backscatter TSAB, Integrated Reflection Coefficient IRC, Slope and Frequency Integrated Reflection FSIR and Temporal Slope(More)
In the early nineties, Mark Weiser, a chief scientist at the Xerox Palo Alto Research Center (PARC), wrote a series of seminal papers that introduced the concept of Ubiquitous Computing. Within this vision, computers and others digital technologies are integrated seamlessly into everyday objects and activities, hidden from our senses whenever not used or(More)

Parma ham technology relies on a few basic points. They are: a fresh meat substantially free of microbial deep contamination, a relatively long phase (up to 100 days) at cold temperatures at the beginning of processing, an uncovered muscular surface as reduced as possible, a long period of maturation. The final product, the matured ham, is the result of a(More)
Small forest streams and their riparian vegetation are closely linked ecosystems. Stream consumers obtain most of their energy from leaf litter provided by the terrestrial vegetation. Thus, understanding the relationship between riparian vegetation, aquatic communities and litter decomposition may help explaining the variability in aquatic communities and(More)
A simple experimental protocol applying a quantitative ultrasound (QUS) pulse-echo technique was used to measure the acoustic parameters of healthy femoral diaphyses of Wistar rats in vivo. Five quantitative parameters [apparent integrated backscatter (AIB), frequency slope of apparent backscatter (FSAB), time slope of apparent backscatter (TSAB),(More)
