Research suggests that implicit strategies adopted during learning help prevent breakdown of automatic processes and subsequent performance decrements associated with the presence of pressure. According to the Constrained Action Hypothesis, automaticity of movement is promoted when adopting an external focus of attention. The purpose of the current experiment was to investigate if learning with...

A 66-year-old man presented with a large squamous cell carcinoma of the right nasal vestibule. He underwent partial rhinectomy and medial maxillectomy followed by staged reconstruction. Reconstruction of a full-thickness nasal defect requires repair of three distinct layers: the skin-soft tissue envelope, subsurface framework and intranasal lining. We report the first use in the UK of an osteoc...

Filling carbon nanotubes with molecules is a route for the development of electronically modified one-dimensional hybrid structures which interplay between electronic structure and key factor. Tuning these energy levels external parameters an interesting strategy engineering new devices materials. Here we show that system composed by quaterthiophene (4T) confined in single-walled nanotubes, pre...

BACKGROUND Arterial pressure waveforms contain important diagnostic and physiological information since their contour depends on a healthy cardiovascular system 1. A sensor was placed at the measured artery and some contact pressure was used to measure the pressure waveform. However, where is the location of the sensor just about enough to detect a complete pressure waveform for the diagnosis? ...

BACKGROUND The use of ultrasound (US) guidance for radial artery cannulation has been shown to improve first attempt success rate, reduce time to successful cannulation, and reduce complications. We sought to determine whether properly trained respiratory therapists (RTs) could utilize US guidance for the placement of radial artery catheters. Primary outcome measurements were successful cannula...

BACKGROUND We determined whether any significant association exists between change in late systolic cardiac load with time, estimated by radial pressure waveform analysis, and development of cardiac hemodynamic stress in individuals with preserved cardiac function. METHODS Brachial-ankle pulse wave velocity, radial augmentation index (rAI), first peak of the radial pressure waveform (SP1), sy...

Background: Transradial access is one of the main access techniques in angiography. This method is technically more difficult as it is associated with radial artery occlusion. Radial artery cannulation from the dorsal surface of the hand in the snuffbox area has been introduced as a suitable solution to overcome some of the disadvantages of the standard radial artery method. This study was cond...

Central aortic pressure waveforms can be calculated from the radial artery pressure waveform using a generalized transfer function to correct for pressure wave distortion in the upper limb. Although validated to standards conventionally applied, reservations are still expressed on use of this process, because of the relatively small number of patients from whom appropriate invasive data were ob...

Assuming arbitrary boundary and initial conditions, a transient thermo-elastic analysis of a rotating thick cylindrical pressure vessel made of functionally graded material (FGM) subjected to axisymmetric mechanical and transient thermal loads is presented. Time-dependent thermal and mechanical boundary conditions are assumed to act on the boundaries of the vessel. Material properties of the ve...
