UNLABELLED The aim of this study was to develop an automatic orientation calibration and reproduction method for recording the natural head position (NHP) in stereo-photogrammetry (SP). A board was used as the physical reference carrier for true verticals and NHP alignment mirror orientation. Orientation axes were detected and saved from the digital mesh model of the board. They were used for c...

This study assessed the final nursing orientation for hospital release in what refers to the medicamental therapeutics in a clinic of hospital internment. The sample was comprised of 38 patients that had hospital release in December of 2001, February of 2002 and of the nurses who oriented them. The technique used for collecting data was non-participant observation. The results obtained were: in...

OBJECTIVES Ultrasound (US) has been shown to facilitate peripheral intravenous (IV) placement in emergency department (ED) patients with difficult IV access (DIVA). This study sought to define patient and vein characteristics that affect successful US-guided peripheral IV placement. METHODS This was a prospective observational study of US-guided IV placement in a convenience sample of DIVA pa...

We describe a correspondence between GLn-invariant tensors and graphs. We then show how this correspondence accommodates various types of symmetries and orientations.

Low back dysfunction is associated in many cases with lumbar lordosis, and tilting the pelvis posteriorly is often recommended for therapeutic purposes. The influence of pelvic tilt on the spinal curves has not been studied. The purpose of this study was to use an objective noninvasive method to determine the effect of the pelvic tilt on the spinal curves in the sagittal plane. Thirty-two healt...

Here we report the first quantitative analysis of spiking activity in human early visual cortex. We recorded multi-unit activity from two electrodes in area V2/V3 of a human patient implanted with depth electrodes as part of her treatment for epilepsy. We observed well-localized multi-unit receptive fields with tunings for contrast, orientation, spatial frequency, and size, similar to those rep...

We present a ten-year-update of the EPR-orientation-model for success of Electronic Patient Records (EPR’s), based on our research. An EPR is seen as a way to make healthcare more efficient and effective. Many initiatives lead to the implementation of EPR’s, but also regional infrastructures for informationand network services are realized. The law to realize a national EPR is rejected by the D...

AIMS Long-term clinical outcomes for ceramic-on-ceramic (CoC) bearings are encouraging. However, there is a risk of squeaking. Guidelines for the orientation of the acetabular component are defined from static imaging, but the position of the pelvis and thus the acetabular component during activities associated with edge-loading are likely to be very different from those measured when the patie...
