A maximum-likelihood (ML) strategy for strain estimation is presented as a framework for designing and evaluating bioelasticity imaging systems. Concepts from continuum mechanics, signal analysis, and acoustic scattering are combined to develop a mathematical model of the ultrasonic waveforms used to form strain images. The model includes three-dimensional(More)
OBJECTIVES Outcome after surgery for rectal cancer is often correlated with surgical technique, without detailed pathological examination of the specimen. Measurement of the number of lymph nodes by a fat clearance technique, mesorectal spread and involvement of the circumferential margins together with clinical findings at operation are correlated with(More)
Over 11 000 new cases of rectal cancer are reported in the UK each year. Recent technical advances have increased interest in local management of the disease. The introduction of screening for colorectal cancer will potentially lead to an increased number of early rectal cancers suitable for local curative treatment. In addition, as the proportion of(More)
OBJECTIVE The repair of sphincter injuries following vaginal delivery is often inadequate. The purpose of this study was to assess the short-term impact of involving a colorectal team in the management of patients with complicated acute severe third-degree tears. PATIENTS AND METHODS Over a 1-year period, four women (age 29-31 years) with acute severe(More)
The NHS Plan (DH 2000), consistent with earlier policy documents, emphasises the need for integrated working between health and social care. However, the path to achieving integration appears to be littered with as many failures of teamworking as successes. This paper reports on an evaluation of the development of a team of practitioners working with(More)

Previous inventory estimates of dioxins (PCDD), furans (PCDF) and dioxin-like PCB emissions from bushfires in Australia have been limited by the small number of published estimates of emission rates. However, the situation has been improved by a recent field study that measured emission factors for PCDD, PCDF and PCBs from 20 prescribed fires, wildfires and(More)
The kevels of sw-gIyceral-3-pbsphate dehydrogenase (GPDHj were determined in the brown adipose tissue (BAT) of different inbred strains of mice. The BAT d the B-FeLB/cJ strain contains twice as much enzyme activity per milfigram protein as do other strains. The appearance of this difference is developentatty dependent, since it is not detected in BAT until(More)

We describe a new two-dimensional position-sensitive detector, now under development, for use in space-borne energetic particle spectrometers. The novel feature of this device is the use of interdigitated pixels to provide both dimensions of position information from a single side of the detector, while a measurement of the energy deposition is derived from(More)
