objectives: the purpose of this study was to compare scapular kinematics during elevation phase of abduction, flexion, and scapular plane elevation phase between fifteen persons with shoulder impingement syndrome (sis) and thirteen persons without it. methods: values of scapular kinematics include scapular superior and lateral translations, upward rotation, external rotation, and posterior tipp...

The pressure-controlled injection tool (PCIT) is the key equipment in process of high-pressure water jet fragmentation solid fluidization exploitation deep-sea natural gas hydrate (NGH). internal flow field erosion wear numerical simulation model PCIT established through computational fluid dynamics software to study influence law and main factors drilling PCIT. laws different physical paramete...

Terahertz time-domain spectroscopy probes anomalous phase-shift caused by wave diffraction from a subwavelength-scale metal slit or aperture. Carrier frequency phase measurements in the far-field region reveals that nearly 30° phase advance is induced from a subwavelength slit diffraction and that 180° phase-advance from a subwavelength aperture. These results indicate that the conventional 90°...

Abstract To further investigate the performance of glycol/diesel dual-fuel engine, we conducted a simulation test by varying injection advance angle diesel engine. Thus, investigated effect different angles on Simulation tests were to study effects ethylene engine when mixing ratio was 15% and 14.6°, 16.6°, 18.6° 20.6°, respectively. The research shows that fuel increases in-cylinder temperatur...

potential fields are due to complex distribution of sources related to susceptibility and mass density variations for magnetic and gravity field respectively. in researching the lateral heterogeneous of different geological bodies, in particular their edge location potential field has some advantages. we mainly refer to linear features such as fault, folding axis, dyke, trend and border of the ...

In this paper, three-dimensional two phase turbulent free surface flow is solved by an in-house code. The incompressible Reynolds average Navier-Stocks equations (RANS) with k-ε turbulence model are solved by the finite volume method in the non-orthogonal curvilinear coordinates. For the modeling of the free surface effect, Lagrangian propagation volume tracking method (VOF-PLIC) is used. The c...
