Fracture-dislocations in the small joints of the fingers are challenging injuries. The surgeon must choose an appropriate treatment based on fracture pattern, joint stability, and injury chronicity. Fracture-dislocations of the proximal interphalangeal joint are notoriously unforgiving, with potential long-term sequelae of residual pain and stiffness. Similar injuries in the distal interphalang...

In the proposed method, the variation of displacement in each time step is assumed to be a fourth order polynomial in time and its five unknown coefficients are calculated based on: two initial conditions from the previous time step; satisfying the equation of motion at both ends of the time step; and the zero weighted residual within the time step. This method is non-dissipative and its disper...

We report time-resolved X-ray absorption measurements after photolysis of carbonmonoxy myoglobin performed at the LCLS X-ray free electron laser with nearly 100 fs (FWHM) time resolution. Data at the Fe K-edge reveal that the photoinduced structural changes at the heme occur in two steps, with a faster (∼70 fs) relaxation preceding a slower (∼400 fs) one. We tentatively attribute the first rela...

A number of individual small advances, taken together, bring us to the beginning of a new domain of optical frequency stability, reproducibility, and measurement. Particular advances include the refinement of Noise-Immune Cavity-Enhanced Optical Heterodyne Molecular Spectroscopy (NICE-OHMS), especially by active control of the residual AM produced by a phase modulator, and by improvement of the...

Perceived depth was measured in a colored stimulus while stimulus movement yoked to head displacement simulated a depth of 1 cm. Velocity judgments were also made for similar stimuli moving at the same average speed but without head movement. Both measures decreased to a minimum of about 30-40% of the veridical values when the stimuli were equiluminous. Perceived depth and speed also decreased ...

The treatment of Bennett’s fracture has varied between physical therapy only and open reduction with osteosynthesis (Gedda 1954). An exact reduction is essential for a good result. Gedda (1954) showed that any residual displacement of the joint was always followed by a secondary arthrosis with permanent symptoms. A new method of treatment by oblique traction was reported in 1955 by Thor#{233}n,...

The technique described in the paper has been developed in order to eliminate or reduce the residual oscillations of suspended bodies, transported by robot arms. It is based on a suitable choice of the motion profile assigned to the linear actuator that drives the system. As it will be clarified in the paper, the motion command is defined through some coefficients that determine its shape. By m...

Most trans-tibial amputation (TTA) patients use a prosthesis to retain upright mobility capabilities. Unfortunately, interaction between the residual limb and the prosthetic socket causes elevated internal strains and stresses in the muscle and fat tissues in the residual limb, which may lead to deep tissue injury (DTI) and other complications. Presently, there is paucity of information on the ...

Experimental study on the influence of fibre content on crack behaviour and propagation in synthetic-fibre reinforced beams has been reported in this paper. The tensile behaviour of metallic fibre concrete is evaluated in terms of residual flexural tensile strength values determined from the load-crack mouth opening displacement curve or load-deflection curve obtained by applying a centre-point...

The study was undertaken in order to determine clinical tactile evaluation of tetanic nerve stimulation (50 Hz, 5 sec) as a means of detecting fade and possible residual curarization. Forty-four patients were studied and 128 clinical evaluations by eight different observers were performed at various levels of neuromuscular blockade. Tetanic fade was detected reliably by clinical evaluation only...
