The aims of this study were to determine factors that cause a leg-length discrepancy (LLD) to the extent that correction is indicated after treatment in developmental dysplasia of the hip and determine whether the LLD may be treated with a percutaneous epiphysiodesis. Twelve children were included in this study. The factors which caused LLD were avascular necrosis, femoral shortening and varus ...

This study highlights three phenomena in directed energy deposition using hybrid laser-arc: bead formation, change the shape because of laser-arc interaction, and formation defects. Unlike arc-based deposition, differs from pre-conceived parabolic or cosine form, which necessitates a new model. The laser-induced flow preheating wire electrode widen molten pool width cause depression top surface...

A pulsed laser ablation backwriting technique with high repetitive rates is implemented for the fabrication of silver coatings on glass surfaces. This method enables geometrical constraint-free deposition metallic coatings. These exhibit sufficiently low electrical resistance to be used as electrodes in dielectric barrier discharge (DBD) plasma elements. Ambient air standard slides explored usi...

Thermally induced liquid-phase deposition method was employed to produce a thin hydroxyapatite (HA) film on a titanium substrate in a metastable calcium phosphate solution. Titanium foil of 100x10x0.02 mm3 was used as a substrate. Prior to HA coating, the substrate was immersed in 5 M NaOH solution at 60 degrees C for 24 hours. Substrate temperature was kept constant at 60 degrees C for 0.5-3 h...

We demonstrate microfluidic laser intra-cavity absorption spectroscopy with mid-infrared lambda approximately 9mum quantum cascade lasers. A deepetched narrow ridge waveguide laser is placed in a microfluidic chamber. The evanescent tails of the laser mode penetrate into a liquid on both sides of the ridge. The absorption lines of the liquid modify the laser waveguide loss, resulting in signifi...

A 42-year-old man developed nephrotic syndrome and rapidly progressive renal failure. Kidney biopsy demonstrated nodular glomerulosclerosis, negative Congo red staining, and no deposition of light or heavy chains. Laser micro-dissection and liquid chromatography with tandem mass spectrometry of nodular lesions revealed the presence of a kappa chain constant region and kappa III variable region,...

We report on the growth of amorphous carbon nitride films sa-CNxd showing the highest conductivity to date. The films were prepared using a layer-by-layer method sa-CNx :LLd, by the cyclical nitrogen radical sputtering of a graphite radical, alternated with a brief hydrogen etch. The photosensitivity S of these films is 105, defined as the ratio of the photoconductivity sp to the dark conductiv...

objective(s): it has been suggested that the efficiency of dry poder inhaler (dpi) is generally low. therefore, the aim of the present research work was to use the solvent treatment of the carrier in dpiformulations to see the possibility of inducing desirable characteristics.   materials and methods: lactose sieve fractions of 63-90 μm were submerged in ethanol or 80% v/v ethanol, methanol or ...

Epitaxial La0:6Sr0:4MnO3 (LSMO) thin films were grown by pulsed laser deposition. Relationships between magnetic properties of LSMO epitaxial thin films and ablation conditions such as ablated spot area and total incident laser energy in a pulsed laser deposition technique were studied. Ablated spot area was controlled by changing the focus lens position and total laser energy. Epitaxial growth...

The phenomenologic diagnosis of depression is successful in increasing diagnostic reliability, but it is a classification scheme without biologic bases. One subtype of depression for which evidence suggests a unique biologic basis is late-life depression (LLD), with first onset of symptoms after the age of 65. LLD is common and poses a significant burden on affected individuals, caretakers, and...
