Selection contributes more strongly to the size and density distributions of SSR loci derived from EST library sequence than from BAC library sequence, although all SSRs likely are subject to similar physical and structural constraints, such as slippage of DNA replication machinery, that may generate increased allelic diversity in AT-rich sequence motifs.
a "Cantilever + voussoir beam" structural mechanics model, b "Tension-slippage" mechanical model, c relationship of supporting intensity and critical rib support force in different mining height.
On the other hand, Z-direction specimens showed higher structural ductility, due to inter-yarn slippage.
In this paper, we established an analytical relationship between the gas slippage factor and the structural parameters of porous media.
We then discuss how to obtain the proper range of clamping force for a given PEMFC stack according to the structural strength, gas tightness, and non-slippage between the contact components under impact.
Based on the surrounding rock deformation and instability feature of longwall mining working face with super cutting height, we establish the roof strata "cantilever + voussoir beam" structural mechanics model and rib "tension-slippage" coupling mechanical model (Pang and Wang 2017a, b), as shown in Fig. 4.
The results show that the structural efficiency of the dome improves with increasing slippage coefficient.
Fractures can be formed by the following three reasons: bursting fractures and contraction fractures formed due to volcanism and cooling (Fig. 2a); structural fractures formed by volcanic rocks deformation and slippage induced by tectonic stresses (Fig. 2e); and dissolution fractures formed by the dissolution of formation fluids during weathering, leaching and burial processes (Fig. 2f).
Recent research has shown that reinforced concrete (RC) beams with concrete-to-concrete casting interfaces where plastic hinges are likely to develop, may experience reduced ductility in comparison to similar structural elements casted at once, due to a potential shear slippage along the casting interfaces.
It is also concluded that the structural performance of isotensoidal toroids can be further improved with increasing the slippage coefficient of the non-geodesic trajectories.
