Weight of the load and its characteristics is considered to be the important risk factor for low back disorders (LBD) among manual materials handlers. Determining weight of the load and the amount of load a person can lift is important in minimizing the incidence of LBD. Among various methods like isometric, isoinertial and isokinetic, isoinertial approach of lifting evaluation is best as it is...

BACKGROUND Composting is one of the most environmentally friendly treatments to inactivate pathogenic organisms or reduce them to acceptable levels. However, even under thermal conditions, some pathogenic organisms such as E. coli could exist for a long time in composting. Such great persistence may increase the possibility of outbreaks of these organisms and further increase the environmental ...

In this paper, numerical analysis of a pile-soil interaction problem is presented considering the parameters influencing the axial load-deformation behavior of the pile embedded in a layered soil medium. The analysis is demonstrated with parametric solutions of a pile with underlain model soil strata under the axial force. An attempt is made to ascertain the extent of influence of elastic prope...

We numerically study the piles generated by continuously dropping a particle on the top of a stable pile in (I + I) dimension. We use a code which has an implementation of static friction in the Molecular Dynamics (MD) simulations of granular material. We study several properties of the pile-the time evolution of mass and slope, and the avalanche size (and duration) distribution. We also study ...

Many factors such as production methods and structural parameters have distinctive influence on the quality and performance of a hand woven carpet. To investigate the effects of some variables, eighteen samples of carpet vary, in knot density, pile height and percentage of slipe wool, were manufactured. Pile yarn performance was assessed by using load-displacement compression curve, obtained fr...

In this study, a coupled model is developed to address the dynamic response of an offshore pile to linear water waves. In the coupled model, the pile and the seabed are treated as a saturated poro-elastic medium described by Biot’s dynamic theory, while the seawater is considered as a conventional acoustic medium. To establish the coupled model, boundary element formulations for saturated porou...

Abstract Rock-socket pile design predominantly depends on the shaft resistance to support load at serviceability state. However, due limited understanding of pile–rock interactions, capacity is normally calculated using empirical correlations. In this study, load-bearing mechanisms rock-socketed piles were investigated through a miniaturised pile–load test setup in soft synthetic rock. X-ray CT...

The article presents a continuation of research results on numerical modelling displacement pile prototype ground (sand) resistance. Numerical resistance consists three stages: restitution initial soil stress state, the restoration state developed during installation and against applied load (pile test). Restitution induced in artificially created sand deposit after compaction procedures was re...
