Ground Potential Rise and Transient Response of the Grounding Grid Based on the Triggered Lightning

open access: yes应用气象学报, 2020
It is extremely dangerous of ground grid potentials which significantly rise when the lightning currents are flowing through the grid. A statistical analysis on 39 return-strokes, 10 M-components and the ground potential rise (GPR) caused by them based ...

Characterization of Preliminary Breakdown Pulse Trains in Negative Cloud-To-Ground Flashes Recorded during A Rainy Season in The Bogota Savannah, Colombia

open access: yesTecnoLógicas, 2022
Lightning-generated electric field measurement is used to characterize cloud-to-ground (CG) flashes. Prior to the first return stroke (FRS), these signals sometimes exhibit a pulse train, known as preliminary breakdown pulses (PBP), whose study provides ...

Return to Work Among Stroke Survivors [PDF]

open access: yesWorkplace Health & Safety, 2019
Despite improvements in the treatment of stroke, many individuals still face cognitive, emotional, and physical impairments. Stroke is a leading cause of serious long-term disability and subsequent failure to return to work (RTW). The purpose of this literature review was to synthesize and discuss the literature relevant to factors affecting RTW for ...

Predictors of Return to Driving After Stroke [PDF]

open access: yesAmerican Journal of Physical Medicine & Rehabilitation, 2013
Although returning to driving is a major concern for many survivors of stroke, predicting who will return to driving after a stroke is often difficult for rehabilitation professionals. The primary aim of this study was to identify patient factors present at admission to an inpatient rehabilitation hospital that can be used to identify which patients ...

Ionization Waves Enhance the Production of X-rays during Streamer Collisions

open access: yesAtmosphere, 2021
Experimental data show that in laboratory sparks, X-rays are produced in time synchronization with the meeting of streamers of opposite polarity just before the final breakdown of the discharge gap.

Stroke [PDF]

open access: yesAAOHN Journal, 2002
1. The two major classifications of stroke are ischemic and hemorrhagic. Ischemic strokes account for 75% of all strokes and result from the complete occlusion of an artery. Hemorrhagic strokes, often caused by aneurysm or hypertension, are caused by the rupture of a cerebral blood vessel and bleeding into the surrounding tissue. 2.

The centrality of work in everyday life after stroke: A qualitative study of long-term stroke survivors

open access: yesScandinavian Journal of Occupational Therapy, 2023
Background Work is an occupation of great concern for younger stroke survivors. Given the high rate of people not working after stroke, there is a need to explore work after stroke from a long-term perspective, including not just an initial return to ...

Characterization of Positive Cloud to Ground Flashes Observed in Indonesia

open access: yesAtmosphere, 2017
The characteristics of 77 electric field changes of positive cloud to ground (CG) flashes in the tropics of Indonesia were investigated. It was found that the arithmetic mean (AM) and geometric mean (GM) values for 0%–100% and 10%–90% rise time were 12.7

Statistical analysis of the primary outcome in acute stroke trials [PDF]

open access: yes, 2012
Common outcome scales in acute stroke trials are ordered categorical or pseudocontinuous in structure but most have been analyzed as binary measures. The use of fixed dichotomous analysis of ordered categorical outcomes after stroke (such as the modified
