A knowledge-based interactive sequential diagnostic system is introduced which provides for diagnosis of multiple disorders in several body systems. The knowledge base consists of disorder patterns in a hierarchical structure that constitute the background medical information required for diagnosis in the domain under consideration (emergency and critical(More)
EST sub-jects a product to highly stressful conditions, Environmental Stress Testing (EST) enhances product quality and reliability by detecting latent or marginal defects in a product. For EST to be effective, testing of a product must achieve a high fault coverage so that as many EST-induced defects can be detected. By uitilizing Boundary-Scan (IEEE Std(More)
AIM To provide further validation of the Environmental Audit Tool (EAT) by describing data on scores from 56 facilities and comparing the scores of facilities with a purpose-built dementia environment with those with non-purpose-built designs. METHODS Fifty-six facilities were assessed with the EAT. EAT scores for 24 purpose-built environments were(More)
The red wolf (Canis rufus) is an endangered species with 194 individuals remaining in the wild and in various captive facilities. Breeding efforts at the Graham, WA site (Point Defiance Zoo and Aquarium) have involved artificial insemination with fresh or frozen semen in an effort to increase population and maximize the genetic potential of the stock.(More)
Protein analysis (using either specific protein quantitation by methods such as HPLC and immunoassays or structural analysis by methods such as LC-MS) usually requires significant sample preparation, including quantitative purification of the target protein from complex sample matrices and potentially enzymatic treatment or labeling. We have developed(More)
Patients with non-cardiac chest pain (NCCP) (n = 387) and cardiac chest pain (CCP) (n = 93) were compared with community controls (n = 81), using a symptom questionnaire that assessed the presence of irritable bowel syndrome (IBS), functional dyspepsia, and oesophageal dysfunction and chest pain characteristics. A significantly (p < 0.05) increased(More)
The deep inferior epigastric perforator (DIEP) flap is normally the first choice in breast reconstruction; however, due to the considerable vascular anatomical variation and the learning curve for the procedure, muscle-sparing transverse rectus abdominis musculocutaneous (TRAM) flaps are still frequently performed to reduce the rate of complications.(More)
BACKGROUND Cognitive and functional decline in dementia generally impairs performance of basic care activities. Staff assistance during these activities frequently results in confusion, anxiety, and distress, expressed through resistance to care (RTC). METHODS A single-system ABA withdrawal design (n = 1) evaluated the effect of video-simulated presence(More)
Five-hundred and thirty-two patients with ischaemic-like chest pain referred for symptom-limited exercise thallium myocardial perfusion studies, were assessed on a range of psychosocial measures. Three groups of patients were identified on the basis of their perfusion studies: (1) normal thallium perfusion; (2) current myocardial ischaemia; and (3) past(More)
Concerns about negative outcomes associated with relocating residents are common. Fifty-five residents of a traditional high-care nursing home moved to new, purpose-built, dementia-specific cottages; 35 additional residents moved into the cottages within the first 8 months of operation. Direct-care staff participated in workshops on engaging residents in(More)
