BACKGROUND Evidence from several populations suggests that war negatively impacts civilian nutrition, physical growth and overall health. This effect is often enduring or permanent, particularly if experienced early in life. AIM To assess whether the number of lifetime displacement experiences and being displaced in infancy were associated with adult height, sitting height, leg length and the...

To the Editor: INTRODUCTION The most common reasons for revision or removal of permanent spinal cord stimulator leads are infection and mechanical failure. Most mechanical failures involve displacement of an intact lead or a fracture of the wires within one or both electrodes. This is the report of a case of catastrophic failure of a paddle lead. The implications regarding certain fixation tech...

Abstract. This paper use the digital signal processor (DSP) TMS320LF2407A control chip is adopted as core of the control system. Three closed loop of the controller, namely electricity, speed and displacement, were designed. Using space voltage vector pulse wide modulation technology (SVPWM), constructed a servo system of permanent magnet synchronous motor(PMSM) based on DSP. Through debugging ...

An 80-year-old man with Ebstein's anomaly and ductus arteriosus aneurysm is reported. He was admitted with bradycardiac atrial fibrillation and right ventricular failure. For the control of brady-arrhythmia, a permanent pacemaker was implanted. Two-dimensional echocardiogram revealed distal displacement of the septal tricuspid valve. Aortography and computed tomography showed ductus arteriosus ...

Permanent and transient effects are discussed that are induced in linear integrated circuits by space radiation. Recent developments include enhanced damage at low dose rate, increased damage from protons due to displacement effects, and transients in digital comparators that can cause circuit malfunc-tions. Methods of selecting and testing devices for space applications are discussed, along wi...

A new structure of linear transverse flux machine (TFM) is presented in this paper. It is in fact a variable reluctance linear machine having permanent magnets on the mover. Its structure and its working principle will be discussed. After a preliminary design of the motor a 3D FEM analysis was carried out before optimizing the designed linear motor. The flux densities in the machine and the sta...

A rare case of talon cusp on geminated permanent central incisor is described. These developmental anomalies cause clinical problems including unsightly dental appearance, occlusal interference, displacement of the affected tooth, attrition, periodontopathy, irritation of the tongue, loss of space and malocclusion. Clinical and radiographic characteristics of these anomalies and modes of treatm...

Due to invisibility and complexity of the underground displacement monitoring, there exit few practical monitoring sensors capable of monitoring the underground horizontal and vertical displacements simultaneously. A novel electromagnetic underground displacement sensor able to monitor both the horizontal and the vertical displacements was proposed in our previous studies and abbreviated as the...

OBJECTIVE The aim of this study to investigate the effects of different polymerization protocols on the cuspal movement in class II composite restorations. MATERIALS AND METHODS Human premolar teeth were prepared with class II cavities and then restored with composite and three-step and two-step etch-and-rinse adhesive systems under different curing techniques (n = 10). It was used a light- e...
