This study was designed to evaluate localized muscular fatigue induced during visual display terminal (VDT) tasks. In the experimental paradigm used, electromyography (EMG) signals were not recorded during the VDT task but during isometric contractions in which the load imposed on the shoulder muscle was kept constant. The change in mean power frequency (MPF) and the root mean square values of ...

We show that digital holography can be combined easily with optical coherence tomography approach. Varying the reference path length is the means used to acquire a series of holograms at different depths, providing after reconstruction images of slices at different depths in the specimen thanks to the short-coherence length of light source. A metallic object, covered by a 150-microm-thick onion...

A 47-year-old male was referred to Emergency Department of our hospital for acute urinary retention. Physical examination showed electrical cable with proximal part introduced into the urethra. Plain abdominal radiograph demonstrated a metallic object in the pelvis and the patient underwent an operation. We used suprapubic cystostomy approach, and the wire was removed from the bladder and urethra.

Low and non-metallic landmines are one of the most difficult subsurface targets to be detected using several geophysical techniques. Ground penetrating radar (GPR) performance at different field sites shows great success in detecting metallic landmines. However significant limitations are taking place in the case of low and non-metallic landmines. Electrical resistivity imaging (ERI) technique ...

We investigate the use of nanopatterned metallic films as transparent conductive electrodes in optoelectronic devices. We find that the physics of nanopatterned electrodes, which are often optically thin metallic films, differs from that of optically thick metallic films. We analyze the optical properties when performing a geometrical transformation that maintains the electrical properties. For...

A technique of measuring contact resistance between an individual nanotube and a deposited metallic film is described. Using laser ablation to sequentially shorten the contact length between a nanotube and the evaporated metallic film, the linear resistivity of the nanotube as well as the specific contact resistivity between the nanotube and metallic film can be determined. This technique can b...

In this paper, we construct metallic Kähler and nearly structures on Riemannian manifolds. For such manifolds with these structures, study curvature properties. Also, describe linear connections the manifold which preserve associated fundamental [Formula: see text]-form satisfy some additional conditions present results concerning them.

Composites with a bulk metallic glass matrix were synthesized and characterized. This was made possible by the recent development of bulk metallic glasses that exhibit high resistance to crystallization in the undercooled liquid state. In this letter, experimental methods for processing metallic glass composites are introduced. Three different bulk metallic glass forming alloys were used as the...

OBJECTIVE Artifacts caused by metallic objects, such as dental crowns, dental implants and metallic orthodontic appliances, are a common problem in head and neck MRI. The aim of this retrospective study was to identify the main metal dental objects that produce artifacts on brain MRIs. STUDY DESIGN Imaged metallic artifacts and their sources were identified. Artifact image plane was rated on ...

Homogeneous plasticity in metallic glasses is generally only observed at high temperatures or in very small structures (less than ≈ 100 nm), so their applications for structural performance have been very limited. Here, nanolaminates with alternating layers of Cu 50 Zr 50 metallic glass and nanocrystalline Cu are synthesized and it is found that samples with an optimal composition of 112-nm-thi...
