The tarsal bones articulate with each other and demonstrate complicated kinematic characteristics. The in vivo motions of these tarsal joints during normal gait are still unclear. Seven healthy subjects were recruited and fourteen feet in total were tested in the current study. Three dimensional models of the tarsal bones were first created using CT scanning. Corresponding local 3D coordinate s...

maximizing economic earnings is the most common goal in cut-off grade optimization of open-pit mining operations. when this is the case, the price of the product has a critical effect on optimum value of cut-off grade. this paper investigates the relationship between optimum cut-off grade and price to maximize total cash flow and net percent value (npv) of operation. in order to visualize this ...

The kinematic flexibility of frog hindlimbs enables multiple locomotor modes within a single species. Prior work has extensively explored maximum performance capacity in frogs; however, the mechanisms by which anurans modulate performance within locomotor modes remain unclear. We explored how Kassina maculata, a species known for both running and jumping abilities, modulates take-off angle from...

Protein motions in the Cys-loop ligand-gated ion receptors that govern the gating mechanism are still not well understood. The details as to how motions in the ligand-binding domain are translated to the transmembrane domain and how subunit rotations are linked to bring about the cooperative movements involved in gating are under investigation. Homology models of the alpha4beta2 nicotinic acety...

In plate tectonic theory a weak asthenosphere is required to facilitate the motions of rigid plates. Partial melt could weaken mantle, in turn impacting convection, but date existence persistent has remained controversial. A wide range scenarios been reported terms location, amount and pathways melt. Here we use data collected by 39 ocean bottom seismometers deployed near equatorial Mid-Atlanti...

The purpose of this study was to design and evaluate an online real time off-ice training program (OOTP) leading the basic figure skating motions, maintaining improving motivation for adult novice skaters. In addition, impact image-based extrinsic feedback on OOTP also investigated. Twenty-two skaters were divided into two groups (without / with group). mainly consisted skill in imitation motio...

The first part of the article provides an overview of both single-axis and multi-axis wave energy converter (WEC) technology, with a particular focus on present and past prototype devices. The second part of the article considers a multi-axis concept device that has been developed and tank tested at Lancaster University by successive Master of Engineering project teams. TALOS is a point absorbe...
