introduction: during the thirty years ago noise pollution increased quickly in the urbane communities that motorcycles are chief sources of noise. the objective of this study is reduction of noise emitted from motorcycle exhaust, applying engineering design. materials and methods: in this pre-experimental study, current condition of noise emitted from motorcycle exhaust and physical parameters ...

Lower limb injuries are the main cause of temporary and permanent disability among motorcyclists in Malaysia. They cause non-fatal but serious injuries requiring hospitalisation. Detailed studies on factors influencing lower limb injuries are justified in an attempt to reduce the occurrence of these injuries. This study presents a computer simulation of the crash behaviour of the basket of a sm...

INTRODUCTION This is very rare case report regarding late ventricular septal defect (VSD) following blunt trauma. CASE REPORT A 23-year-old motorcycle rider lost control and crashed to another motorcycle. He was transferred to emergency department by emergency medical services. Initial evaluation revealed some minor trauma which was managed, and he was discharged. There was a lately developed...

BACKGROUND The economic impact of helmet use remains controversial. Previous studies of injured motorcyclists suggest a marginal inpatient hospital cost difference between helmeted and unhelmeted riders. The purpose of this study was to expand the economic analysis of motorcycle helmet utilization to the point of injury by including motorcycle crash patients who do not require hospital admissio...

INTRODUCTION Motorcycles have become an increasingly popular mode of transportation despite their association with a greater risk for injury compared with automobiles. Whereas the recent incidence of annual passenger vehicle fatalities in the United States of America (USA) has progressively declined, motorcycle fatalities have steadily increased in the past 11 years. Although motorcycle injurie...

OBJECTIVE To conduct a comparative analysis of the lesions found among motorcycle riders involved in traffic accidents and victims of other mechanisms of blunt trauma. METHODS Analysis of data prospectively collected on protocols for trauma patients older than 13 years, admitted from 06/10/2008 to 09/01/2009, victims of blunt trauma. Data collected included trauma mechanism, vital signs at ad...

Owing to noticeable differences of the characters between the electrical and the conventional gasoline-powered motorcycles, such as heavier in weight, lower in mass center position and slower in forward speed, the control and design considerations of the electrical motorcycles are not the same as conventional motorcycles. In this paper, the rider upper body lean control system is considered as ...

Triumph was started by two Germans, Siegfried Bettman and Mauritz Schulte, and was the company was founded in 1886 making bicycles and based in Coventry. A quarrel led to a split and Schulte continued, focusing on simple reliable machines. Triumph hit financial problems in the 1930's during the depression, and was sold to Ariel in 1936. It was at this point that Edward Turner was appointed Chie...

The effect of cannabis and cocaine use on non-fatal traffic injuries and use of motorcycle helmets or car seatbelts was assessed in a nationwide sample of 17,484 car or motorcycle drivers surveyed in 2005 in Spain. Logistic regression was used to adjust for distance driven and potential confounders. Cocaine use ≥ 1 day/week and cannabis use >4 days/week were associated with more traffic injurie...
