Caesarean sections (CS) have risen annually in Australia for over 10 years reaching 31.6% of births in 2010 [1] (Figure 1), compared with the Organization for Economic Co-operation and Development average of 26% in 2009 [2]. A previous CS increases the likelihood of a repeat caesarean sec...
Conversely, the resistance to fatigue crack growth is even superior and the fracture toughness comparable to that of conventional DCI. Keywords: heavy-section ductile cast iron; chunky graphite; fatigue limit; fatigue crack growth resistance; fracture toughness 1. Introduction Low production cost and ...
Changes were observed in the distribution of velocities and shear stresses, varying along the surveyed section of the river. In the first year after their application, an increase in velocity at the deflectors can be observed (from 0.2 m·s−1 to 0.6 m·s−1 in the deflector cross-...

According to the springback theory of small curvature plane bending, the pure bending process and springback of in-plane curved beam with symmetrical section were analyzed, and the over-bend straightening theory was established. Based on this, the straightening mechanism of the existing over-bend ...
