A Comparison of Different Engineering Models for Computation of Lightning Magnetic Field of Negative First Strokes [PDF]

open access: yesTelfor Journal, 2012
A comparison of different engineering models results for a lightning magnetic field of negative first strokes is presented in this paper. A new function for representing double-peaked channel-base current is used for lightning stroke modeling.

Stroke Location Is Not Associated With Return to Work After First Ischemic Stroke [PDF]

open access: yesStroke, 1999
Background and Purpose —In prior studies, age, race, job category, disability, and cortical functions such as praxis, language, and memory have been associated with vocational outcome, but the influence of stroke location on return to work has never been critically examined. Methods

The (im)possibilities of returning to work after a stroke [PDF]

open access: yesWork, 2017
BACKGROUND: What a stroke means for working-age persons has not been sufficiently studied from a sociological perspective. OBJECTIVE: This article uses the empirical material of a larger study to describe and analyze how institutional practices and discourses influence attempts to return to work after a stroke.

Modeling and analysis of sliding motion of arc root along OGW during lightning strike

open access: yes电力工程技术
Overhead ground wire (OGW) is an important equipment to prevent transmission wire from being struck by lightning. When OGW is struck by lightning, the sliding motion of arc root causes different damage mechanism. Therefore, it is necessary to analyze the

Income and education as predictors of return to working life among younger stroke patients

open access: yesBMC Public Health, 2011
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 ...

Characteristics of a multi-stroke “bolt from the blue” lightning-type that caused a fatal disaster

open access: yesGeomatics, Natural Hazards & Risk, 2019
Observational data from the low-frequency electric-field detection array (LFEDA) and radar were used to study the precise location of a fatal accident caused by a lightning in Conghua, Guangzhou, China, 2017.
