Clinical and laboratory assessments in rheumatoid arthritis and osteoarthritis precede imaging methods in both defining diagnosis and determining response to therapy. Some assessments are similar in both diseases, e.g. measuring joint pain, the number of involved joints and functional impairment. There are also areas of difference; for example, rheumatoid arthritis is a systemic disease with im...

in this investigation, the performance of a tower for absorption of sulphur dioxide gas into calcium carbonate solution has been studied. the trays had no downcomer and the tower itself was a scaled down pilot from industrial equipment. the industrial scale tower was used for clean up of 110000 m3/hr gas using 40 m3/hr alkaline solution. the study was composed of two parts. in the first section...

OBJECTIVES To understand the expressed needs of physicians and their patients with respect to arthritis care, identify areas of agreement and disagreement in doctor and patient views of arthritis care, and to determine the types of educational programs needed. METHODS Focus group interviews were conducted with 14 physicians of varied specialties and 12 patients with arthritis from Oxford Heal...

An aerostatic spherical bearing has been developed for parallel kinematic machines. The design is based on a ball and socket configuration and is preloaded by permanent magnets arranged about the socket. High pressure air is injected through three orifices into the cavity between the ball and socket to produce a low friction, high accuracy interface. Joint accuracy is measured using a coordinat...

Objectives. To assess interreader agreements and a learning curve between three (senior, junior, and beginner) different experienced musculoskeletal ultrasonographers. Senior served as the imaging "gold standard". Methods. Clinically dominant joints (finger, shoulder, knee, tibiotalar, and talonavicular) of 15 rheumatoid arthritis (RA) patients were examined by three different experienced ultra...

INTRODUCTION To determine the validity and reliability of patients' self-performed joint counts compared to joint counts by professional assessors in rheumatoid arthritis (RA) patients in different disease activity states. METHODS In patients with established RA we determined the inter-rater reliability of joint counts performed by an independent evaluator and the patient using intraclass cor...

It is well known that bone adapts its microstructure in response to loading. Based on this form-follows-function relationship, we previously developed a reverse approach to derive joint loads from bone microstructure as acquired with micro-computed tomography. Here, we challenge this approach by calculating hip-joint loading patterns for human and dog, two species exhibiting different locomotio...

fracture mapping of late permian-early triassic flat-lying sedimentary rocks in the sydney basin,new south wales, australia, shows that joints developed originally in extension were faulted in subsequentevents. joints with a regional distribution fall into two (early and late) formed groups. group i joints propagatedhorizontally and never interfered with each other. these joints were subsequent...

UNLABELLED We previously studied hospitals in the United States of America that are losing money despite limiting the hours that operating room (OR) staff are available to care for patients undergoing elective surgery. These hospitals routinely keep utilization relatively high to maximize revenue. We tested, using discrete-event computer simulation, whether increasing patient volume while being...
