Granular Pile Anchor (GPA) considers one of the solution foundation techniques, designed to mitigate the lifting of the sole resulting from expansive soils. This study work is to investigate the uplift movement response of (GPA) in expansive soil. The laboratory tests have been performed on an experimental. The effects of several parameters, such as length (L) of (GPA) and diameter (D), the thi...

background: manual material handling is one of the major health and safety hazards in industry. this study aims to assess the lifting tasks, before and after intervention using niosh lifting equation and manual handling assessment charts (mac). methods: this interventional study was performed in 2011 in a tile manufacturing industry in hamadan, located in the west of iran. the prevalence of mus...

background: low back pain caused by work, ranked the second after cardiovascular diseases, are among the most common reasons of patients’ referral to the physicians in iran. this study aimed to determine the changes in back compressive force when measuring maximum acceptable weight of lift in iranian male students. methods: this experimental study was conducted in 2015 on 15 young male students...

BACKGROUND AND AIMS  Non-lifting large laterally spreading colorectal lesions (LSLs) are challenging to resect endoscopically and often necessitate surgery. A safe, simple technique to treat non-lifting LSLs endoscopically with robust long-term outcomes has not been described. METHODS  In this single-center prospective observational study of consecutive patients referred for endoscopic mucosa...

Explanations for the ineffectiveness of lifting training often focus on the nature of the workplace. However, the process through which workers select a lifting method may contain priorities based on energy expenditure, unique anthropometry, lifting experience, personality profile or other characteristics of the individual worker. This empirical investigation studied the lifting technique selec...

The bearings of a flywheel energy storage system (FESS) are critical machine elements, as they determine several important properties such self-discharge, service life, maintenance intervals and most importantly cost. This paper describes the design low-cost, low-loss bearing for 5 kWh/100 kW FESS based on analytical, numerical experimental methods. special operating conditions rotor (e.g., hig...
