B , a puclla publica, aged about 28, was attacked with cholera while an inmate of the Lock Hospital. Vomiting and purging commenced at 8 p. m. on 27th May, and both continued, with remissions varying froiu half an hour to one hour, until 7 a m. of 28th.

The concept of the barbarian has been an enduring presence in the antiquarian and archaeological study of European societies. Indeed the idea of the barbarian as an adjective and concept continues to influence both scholarly and popular perceptions of Prehistory, the Ancient World and Early Medieval societies. Moving beyond studies of the shifting attitudes to the barbarian within successive an...

The radiation from the mixed layer into the interior of the ocean of near-inertial oscillations excited by a passing storm in the presence of the beta effect is reconsidered as an initial-value problem. Making use of the fact that the mixed layer depth is much smaller than the total depth of the ocean, the solution is obtained in the limit of an ocean that is effectively infinitely deep. For a ...

BACKGROUND There have been few scientific studies that have examined usage of human growth hormone to accelerate recovery from injury. The hypothesis of this study was that human growth hormone would accelerate tendon-to-bone healing compared with control animals treated with placebo in a rat model of acute rotator cuff injury repair. METHODS Seventy-two rats underwent repair of acute rotator...

abstractthe purpose of this study was to investigate the controllable operating parameters influence, including ph, solid content, collector, co-collector, and depressant dose, and conditioning time, on apatite flotation kinetics. four first order flotation kinetic models are tested on batch flotation time-recovery profiles. the results of batch flotation tests and the fitting of first-order ki...

An understanding of the remodelling of tendon is crucial for the development of scientific methods of treatment and rehabilitation. This study tested the hypothesis that tendon adapts structurally in response to changes in functional loading. A novel model allowed manipulation of the mechanical environment of the patellar tendon in the presence of normal joint movement via the application of an...
