OBJECTIVE The capacity of articular cartilage matrix to recover during 50 weeks of remobilisation after an atrophy caused by 11 weeks of immobilisation of the knee (stifle) joint in 90 degrees flexion starting at the age of 29 weeks, was studied in young beagle dogs. METHODS Proteoglycan concentration (uronic acid) and synthesis ([35S]sulphate… (More)
Cultured bovine articular cartilage was subjected to 50 ms, 0.5-1.0 MPa compressions repeated at intervals of 2-60 s for 1.5 h and simultaneously labeled with 35SO4. The compression was delivered with a 4-mm-diameter nonporous loading head on an 8-mm-diameter cartilage explant. This method created directly compressed (central) and uncompressed (border)… (More)
E-commerce has been slowed down due to the fact that consumers find Internet an untrustworthy environment, and are not willing to be guinea pigs of a new service and take unnecessary risks by giving their credit card number to an online service they cannot really trust. Yet, if e-commerce is to thrive, creating consumer trust is a necessity – or else there… (More)
Hyaluronan (HA), an extracellular high-molecular-mass polysaccharide, is supposed to be involved in the growth and progression of malignant tumours. We studied the cellular expression of HA in 215 operated stage I-IV gastric cancer patients using a specific biotinylated probe. Most (93%) of the tumours showed HA staining in their parenchyma, whereas the… (More)
OBJECTIVES Articular cartilage proteoglycan content is controlled by joint loading. This study aimed to elucidate the role of hydrostatic pressure in this regulation. METHODS Primary cultures of chondrocytes from bovine articular cartilage, grown on coverslips, were subjected to 5, 15, or 30 MPa hydrostatic pressure, applied continuously or cyclically at… (More)
In this paper, we present a quick and easy technique to present user profiles graphically. The technique is believed to be specially suitable for communicating user data in multidisciplinary design teams. It was invented in a explorative design project focusing on future telecommunications services in department store contexts.
Bluetooth-technology enables objects to communicate with each other, humans to communicate with each other, and humans to communicate with objects. This paper discusses some possible ways to develop context awareness to enhance the Bluetooth-devices ability to "guess" the groups that Bluetooth (end) user is seeing and using at each moment.
This paper addresses the social aspects embedded and, till now, mostly neglected in introducing wearable technology to the "common man". These include personal, psychological, practical, and social issues as related to wearables. The privacy issues that using a wearable will come along, are also touched on briefly.
