The aim of this study was to summarise the scientific evidence on the prevalence of psychoactive substance use and on the factors associated with their intake among truck drivers. A systematic review was performed in the databases PubMed, Scientific Electronic Library Online, Latin American and Caribbean Health Sciences, and Cochrane and 36 cross-sectional studies were identified with quantitat...

More than one year has passed since refrigerant for refrigerator was changed from CFC12 to HFC134a. Long term reliability of refrigerator in HFC134a refrigerant system is mainly dependent on lubrication of moving parts of compressor and clogging of capillary tube. To maintain better practical reliability in components in compressor such as refrigeration lubricant,metallic materials and motor in...

Refrigerator ownership in rural China increased from 14% to 45% over the period 2001-2010.We test the impact on demand for food, particularly meat, using fixed-effect and demand system approaches based on provincial data. Results suggest that rising refrigerator ownership had a negative effect on rural at-home meat demand.

work-related musculoskeletal disorders (wmsds) are common among drivers and official workers. musculoskeletal disorders are frequent causes of absenteeism in many countries. the aim of this study was to determine the prevalence of musculoskeletal disorders and risk factors associated with these symptoms. a total of 346 workers and truck drivers were participated in this case-control study. all ...

-Lymph-node cells of (AKR x C3H) F1 leukaemic mice showed a considerable increase of glycolytic activity and 02 consumption. The glycolytic enzymes phosphofructokinase, pyruvate kinase, aldolase and lactic acid dehydrogenase showed increased activities in leukaemic conditions. Studies on permeabilized leukaemic and normal lymph-node cells, and assays on partially purified phosphofructokinase an...

Freight trucks are an important component of the nation s highway traffic. Due to their physical and operational characteristics, they can significantly impact traffic system performance, safety, and the travel experience of non-truck drivers. Methodological gaps exist in the literature on modeling car–truck interactions that do not result in crashes, especially those resulting from non-truck d...

OBJECTIVE This study aimed to determine if occupational exposure to whole-body vibration is associated with cervical intervertebral disc herniation among container truck drivers. METHODS We conducted a walk-through survey among container truck drivers and unexposed workers. We also measured the vibration hazard of the container truck over the driver's back and seat when the driver was loading...
