In this paper, an attempt has been made to model DPM flow patterns in the vicinity of man riding vehicle(s) operating a coal mine environment. The are modelled using techniques computational fluid dynamics (CFD) and validated field experimental measurements. models show that if vehicle is stationary, particles dispersed towards center gallery. Beyond 20 m downstream vehicle, occupy entire cross...

This paper presents a detailed account of computational fluid dynamics (CFD) simulations undertaken to investigate the influence of intake (ventilation) air velocities on the flow patterns of diesel particulate matter (DPM) generated by a man-riding vehicle operating in a straight rectangular cross section tunnel in an underground coal mine. The simulation results are validated against an earli...

INTRODUCTION The purpose of this study was to characterize the physiological demands of recreational off-road vehicle riding under typical riding conditions using habitual recreational off-road vehicle riders (n = 128). METHODS Comparisons of the physical demands of off-road vehicle riding were made between vehicle types (all-terrain vehicle (ATV) and off-road motorcycle (ORM)) to the demands...

Motor vehicle accidents continue to cause thousands of life threatening injuries or mortality (nearly 45,000 deaths in 2021) the United States. A sixteen year-old young man riding a motorcycle was severely injured when struck by an automobile driven individual under influence alcohol. Multiple long bone fractures, left renal artery torn off aorta, with non-function kidney, urinary bladder ruptu...

CONTEXT Child and adolescent bicycling is beneficial, but injuries occur and can be severe and costly. OBJECTIVE To systematically review the individual and environmental factors associated with bicycling injury risk in children and adolescents. DATA SOURCES Fourteen electronic databases were searched. STUDY SELECTION Two authors independently assessed potentially relevant articles for el...

BACKGROUND National estimates of all-terrain vehicle (ATV) riding patterns among youth in the USA are lacking. METHODS We analysed the 2011 YouthStyles survey to estimate the proportion of 12-17 year olds in the USA who had ridden an ATV at least once during the past 12 months and summarise their patterns of helmet use. RESULTS Of the 831 youth respondents, an estimated 25% reported riding ...

background: motorcycle has been one of the vital modes of transportation worldwide. it is quite difficult to identify the risk factors that affect muscular discomfort among motorcyclist due to not much research having been carried out on the motorcyclist. the purpose of this study was to have a better understanding of the risk factors of muscular discomfort among motorcyclist due to motorcycle ...

American Indians, especially those residing in the Northern Plains, experience considerable preventable morbidity and mortality from alcohol-related motor vehicle events. Research focusing on unintentional injuries associated with drinking drivers has disregarded the epidemiology of their passengers, who are equally at risk. The purpose of this investigation was to define the prevalence of moto...

Course holding by cyclists and moped riders includes both steering alongside a course and stabilising the vehicle. Inability to hold course may lead to conflicts with other road users. To design safe bicycle and moped facilities, and to consider the safety of those existing, knowledge about performance during course holding is necessary. Based on a literature survey, the article discusses how c...

STUDY OBJECTIVE We examined the association between driver restraint use and child emergency department (ED) evaluation following a motor vehicle crash (MVC). METHODS This cohort study included child passengers aged 0-12 years riding with an adult driver aged 21 years or older involved in a MVC in Utah from 1999 to 2004. The 6 years of Utah MVC records were probabilistically linked to statewi...
