Engineering fatigue fracture failure is one of the most common phenomena of mechanical and structural failure, statistically representing approximately 50 to 90% of total mechanical damage [1]. Lattice structures have been widely used in crane booms, steel plants, parking garages, offshore platforms and other fields [2] to [4]. In a crane, the lattice boom has better mechanical properties compa...

Engineering fatigue is a very prevalent and dangerous phenomenon that limits the useful life span of mechanical structures. It can be found in most engineered structures machinery are made from metallic or composite materials. The prediction methodology under variable amplitude loading (VAL), however, has not reached maturity due to complexity loading. This results load sequence effects, which ...

Background Several risk factors for the development of running injuries have been identified, however, the etiology is still not completely clear [1]. A number of prospective studies have identified gait-related risk factors for lower leg overuse injuries [2-6]. On the other hand, running injuries only develop by overloading the lower extremity. Fatigue can therefore be hypothesized to be a pri...

CONTEXT In their first year of postgraduate training, interns commonly work shifts that are longer than 24 hours. Extended-duration work shifts are associated with increased risks of automobile crash, particularly during a commute from work. Interns may be at risk for other occupation-related injuries. OBJECTIVE To assess the relationship between extended work duration and rates of percutaneo...

In this short communication, we assert that mental health has a crucial role in the primary prevention of sexual and gender-based violence (SGBV). However, we found that most research and practice to date has focused on the role of mental health post-violence, and SGBV primary prevention is relying on public health models that do not explicitly include mental health. Yet, key concepts, processe...

Background: Fatigue as a result of prolonged activity may increase injury risk and decrease performance. Purpose: To provide insight in the development of fatigue experiences during soccer matches and the extent to which general performance capacity (i.e. overall physical fitness, psychological fitness, and recovery) contributes to these fatigue experiences. Methods: 450 Soccer players from the...

Driving while fatigued is a serious risk-taking behavior among college students. Accident data were reviewed and a behavioral risk factor survey undertaken at a large private university. The findings indicated that 86 motor vehicle fatalities occurred among students at the university in the last 15 years. The authors estimated that falling asleep at the wheel may have caused 62 of these acciden...

This 6 year follow-up study was designed to evaluate the long-term physical, psychological and social outcomes of severely injured patients (Injury Severity Score of greater than or equal to 16). Patients were treated at the University Hospital Groningen, the Netherlands, between January 1989 and December 1989. Outcomes were assessed using a postal questionnaire. After injury, the 55 respondent...

Sporting injuries may be generally divided into those caused by an impact, where there is a sudden increase in the force applied to the body (an inappropriate landing in Australian football or rugby) or those produced through overuse. Overuse injuries are generally due to overload or repetitive microtrauma of the musculoskeletal system, where a number of repetitive forces each lower than the cr...
