OBJECTIVE To determine bias due to loss of participants (attrition bias) in a prospective cohort study. DESIGN A multi-centre prospective cohort study. SUBJECTS A total of 225 individuals with a spinal cord injury from 8 Dutch rehabilitation centres. METHODS Participants were considered non-participants when no information was collected at the measurement one year after discharge from inp...

OBJECTIVE The objective of this study was to implement potentially better practices for discharge planning in the NICU. METHODS Each participating hospital completed a self-assessment tool on discharge planning and a staff satisfaction survey. Parent satisfaction data were obtained from an Internet-based survey. Many projects regarding discharge planning were completed at each participating c...

abstract weirs are the most common structures for discharge measurement in engineering research. streamline curvature, non hydrostatic pressure distribution on weir and nappe adherence to the weir lead to differences between calculated and measured discharges. thus discharge coefficient, which is the ratio of real and theoretic discharges, is usually less than unity. in circular weirs the press...

Discharge measurement is a basic tool for process control and modelling in both natural and urbanized catchments. One of the limitations of measurement methods in use is the direct contact between the velocity measurement device and flowing liquid, resulting in maintenance difficulties. Thus, this paper deals with the design, laboratory testing and field verification of a nonintrusive discharge...

The laser ablation fast pulse discharge plasma spectroscopy (LA-FPDPS) technique has demonstrated its validity to enhance the optical emission of laser-induced plasma. It has the potential to improve the performance of traditional LIBS measurement. Very recently, LA-FPDPS with a nanosecond pulse discharge circuit has been developed, which has a better capability to enhance the optical emission ...
