The spin structure of head-to-head domain walls in Ni80Fe20 structures is studied using high-resolution photoemission electron microscopy. The quantitative phase diagram is extracted from these measurements and found to exhibit two phase boundaries between vortex and transverse domain walls. The results are compared with available theoretical predictions and micromagnetic simulations and differ...

The articular facet joints (AFJ) play an important role in the biomechanics of the spine. Although it is well known that some AFJ dimensions (e.g. facet height/width or facet angles) play a major role in spinal deformities such as scoliosis, little is known about statistical correlations between these dimensions and the size of the vertebral bodies. Such relations could allow patient-specific p...

The scattering of a scalar wave propagating in a waveguide containing weak penetrable scatterers is inspected in the Born approximation. The scatterers are of arbitrary shape and present a contrast both in density and in wavespeed (or bulk modulus), a situation that can be translated in the context of SH waves, water waves, or transverse electric/transverse magnetic polarized electromagnetic wa...

A series of experimental runs were carried out on a small blown film line to investigate the effect of processing parameters on the mechanical properties of the film that was produced. Three different dies were used and for each die the throughput (mass flow rate), freeze line height and blow-up ratio were varied, with take-up velocity adjusted to give a fixed nominal gauge (film thickness). On...

Concrete guideways for proposed MAGLEV vehicles may be reinforced with electrically conducting and magnetizable steel rebars. Transient magnetic fields due to passing MAGLEV vehicles will then induce transient currents in the rebars leading to power dissipation and temperature rise as well as Lorentz and magnetization forces on the rebars. In order to evaluate if this heating and force on the r...

The height of the unwelded root part in T and X welds whose length exceeds the sound-beam width at the contact point between the sound and the reflector can according to methods known today only be estimated by applying the tandem technique with two ultrasonic transverse probes from one single access area, or two access areas, the latter usually not possible in practice. However, with sheets ha...

PURPOSE This study was conducted to evaluate the ability of sonography to visualize the ulnar nerve at Guyon's canal and the common peroneal nerve dorsal to the fibular head and to test for correlations between nerve measurements and subject characteristics. METHODS We used a 5-12-MHz linear-array transducer in sonographic evaluation of 15 healthy adult volunteers. We evaluated the correlatio...

PURPOSE The purpose of this study was to investigate the differences in the axial and coronal parameters of lumbosacropelvic morphology among a population with spondylolysis and healthy individuals by using 2- and 3-dimensional (3D) reformatted computed tomographic images. Moreover, this study aimed to evaluate the differences in sagittal geometry. MATERIALS AND METHODS The stone protocol abd...

Perennial rhinitis with an allergic component (PRAC) in association with chronic mouthbreathing has been thought to cause skeletal open-bite facial type and narrow transverse facial dimensions. The object of this study was to supply data for this theory and to determine if allergy management would alter the course of facial growth. When a group of children, aged 5 to 10 years, with PRAC was com...

Lichtenstein technique requires identification of the iliohypogastric, ilioinguinal, and genital branch of the genitofemoral nerves.The aim of the study was to verify if the transverse incision is suitable for identification of the iliohypogastric, ilioinguinal, and genital branch of the genitofemoral nerves.This study included 29 patients who underwent hernioplasty, and also 10 dissections of ...
