BACKGROUND Loss of employment contributes significantly to the burden of stroke on individuals and society. There is limited information on factors influencing return to work after stroke. OBJECTIVES To investigate the frequency and determinants of return to paid work after stroke in a multi-ethnic urban population. METHODS Patterns of return to work were examined among people with first ev...

[1] We present a statistical analysis of the salient characteristics of current waveforms for 206 return strokes in 46 rocket-triggered lightning flashes. The flashes were triggered during a variety of experiments related to the interaction of lightning with power lines that were conducted from 1999 through 2004 at the International Center for Lightning Research and Testing at Camp Blanding, Fl...

[1] Using electric and magnetic field and field derivative sensors arrayed over an area of about 1 km, we measured the close fields of stepped leaders and first return strokes in 18 negative cloud-to-ground lightning flashes at distances to individual sensors ranging from about 100 m to about 1 km. We present examples of the close field waveforms along with their statistical characterization as...

Different functions have been used to model the lightning return-stroke current with the aid of direct current measurements at tall structures. In this paper, a comparison between the Pulse function and Heilder function is carried out to find out the suitability of each of these functions for simulating the lightning return-stroke current, measured at the CN Tower. An automated system for deter...

BACKGROUND Socioeconomic conditions are not only related to poor health outcomes, they also contribute to the chances of recovery from stroke. This study examines whether income and education were predictors of return to work after a first stroke among persons aged 40-59. METHODS All first-stroke survivors aged 40-59 who were discharged from a hospital in 1996-2000 and who had received income...

BACKGROUND Successful return to work after stroke may improve economic circumstances, quality of life and overall life satisfaction, but not all stroke survivors are able to return to work. AIM Our aim was to determine what proportion of previously employed patients return to work after an acute stroke resulting in mild to moderate disability and to examine factors associated with a successfu...

We infer peak currents from radiation electric field peaks of 48 positive return strokes acquired at the Lightning Observatory in Gainesville (LOG), Florida, in 2007-2008. In doing so, we use the transmission line model, NLDN-reported distances, and assumed return-stroke speed. From a similar analysis of negative first and subsequent strokes, it appears that the implied return-stroke speed in t...
