BACKGROUND Concerns were raised about the possibility of a high prevalence of musculoskeletal symptoms in a truck assembly plant. AIM The aim of this study was to investigate the prevalence of musculoskeletal symptoms in a group of truck assembly workers. METHOD A cross-sectional study of 461 truck assembly workers was carried out using a modified version of the Nordic questionnaire and the...

Abstract: Each year more than 40,000 people die as a result of highway crashes, and 1 in 8 of those fatalities involve commercial motor vehicles. USDOT has set an ambitious goal of a 50 percent reduction in truck-related facilities by the end of this decade. Meeting that goal will involve finding ways of improving the performance of all elements of the system – the driver, the roadway, and the ...

freight service is reinvested in passenger service improvements. The freight carrier, in shifting goods from trucks to rail, can potentially benefit from (a) more reliable travel times for goods, particularly during periods of nonrecurrent congestion, (b) cheaper transport costs, and (c) fewer truck accidents. Society may benefit from reduced truck traffic through reductions in (a) harmful gree...

An analysis of Victorian truck rollover crashes using data from the VicRoads Road Crash Information System database and National Transport Insurance (NTI) was undertaken for 2003 to 2007. Recommendations for reducing the frequency and severity of truck rollover crashes were made based on the analyses and supported by relevant literature. The Victorian crash data indicated that of all truck cras...

This paper presents the results of a statistically designed experiment with eight all-refrigerator cabinets. The cabinets were designed with a view to be identical except for the fact that each cabinet was fitted with a specific non-adiabatic capillary arrangement. These cabinets were tested to the New Zealand test standard (NZS 6205.2) at 32°C ambient temperature and then the tests were repeat...

The US coal mining industry consumes approximately 142 billion kWh per year of energy. The US Department of Energy estimates that the industry‟s annual energy consumption can be reduced by 49% (24.6 billion kWh/year by using currently available best practices and a further 44.8 billion kWh/year with more research). This constitutes nearly $3.7 billion of potential savings on coal production cos...

A computer model representing a two-evaporator, two-intercooler refrigerator-freezer opera ting at steady-state with nonazeotropic refrigerant mixtures (CYCLEZ) has been developed at Oak Ridge National Laboratory (ORNL). This model is being used to assess the effects of system desig n and operating parameters on the cycle performance of a refrigerator-freezer designed around the L orenzMeutzner...
