Eighty-seven feet have been reviewed after arthrodesis of the first metatarsophalangeal joint stabilised by chromic catgut. Radiological union was present in 90% of patients at the mean review time of six years. Twenty-four patients had significant metatarsalgia before operation and only two failed to improve afterwards. Excellent or good subjective results were reported in 94% of patients at r...

Lancet of that date of some cases of warts on the genitals treated by Mr John Marshall, at University College Hospital, with chromic acid. In one severe case, after having tried all manner of caustics with only temporary benefit, Mr Marshall found the application of chromic acid, gr. 100 to ?j. of water, quite successful, and much less painful than any other escharotic he had tried. In the Lanc...

Damping in air gaps is studied at RF frequencies and modelled with a viscoelastic wave propagation model, since the traditional squeezed-film damping model is not valid in the MHz regime. The FEM study shows that above a certain frequency the wave propagation in the air gap can be modelled assuming closed damper borders. This closed-border problem is solved analytically from the linearized Navi...

The band gap and optical properties dielectric functions and optical constants of Ge thin films with various thicknesses below 50 nm, which were synthesized with electron beam evaporation technique, have been determined using spectroscopic ellipsometry and UV-visible spectrophotometry. The optical properties are well described with the Forouhi–Bloomer model. Both the band gap and optical proper...

Chromic acid anodizing (CAA) is still being used today for corrosion protection of fatigue-critical components in the aeronautic industry due to lack feasible alternatives. Ce-containing sulfuric (SAA) has been identified as a promising strategy development alternatives toxic CAA. This work explores thin (TSAA) focusing on following effects: (i) current density and voltage values; (ii) concentr...

nanocrystalline titanium (iv) oxide paste has been deposited on fluorine doped tin oxide glass substrate by the blade method. the deposited film was subjected to thermal treatment to obtain an electrode foe a photo-electrochemical cell. the electrode was sensitized with prophyrin dye which was a local dye extracted from carica papaya leaves. avaspec 2.1 spectrophotometer was used to obtain the ...

There is much evidence supporting the hypothesis that magnitude of nerve root mechanical injury affects the nature of the physiological responses which can contribute to pain in lumbar radiculopathy. Specifically, injury magnitude has been shown to modulate behavioral hypersensitivity responses in animal models of radiculopathy. However, no study has determined the mechanical deformation thresh...
