Fibres are responsible for mechanical properties of FRP bars, on which the deformational behaviour of reinforced concrete structures depends.
This paper involves examination of operating conditions of replaceable elements of frontal safety deformation zones, and influence of individual elements in absorption of impact energy, while determining qualities of these elements based on generalized deformational characteristics.
Plagiocephaly, or deformational plagiocephaly, which is the flattening of one side of the head, has become increasingly common since the early 1990s when the American Academy of Pediatrics began recommending that infants be positioned on their backs to sleep in an effort to prevent SIDS.
Deformational plagiocephaly (DP), a frequently occurring pediatric condition, is characterised by changes in skull shape in the absence of craniosynostosis.
Positional or deformational plagiocephaly may occur when external forces shape an infant's skull while it is still soft and malleable, such as extended time spent lying on a hard surface or in one position.
Thin-sections cut approximately through the centers of the large garnet porphyroblasts were oriented orthogonal to the dominant matrix foliation, and either parallel or orthogonal to the weakly-developed mineral stretching lineation in these samples in order to identify metamorphic mineral assemblages and deformational fabrics preserved in the matrix and within the garnet porphyroblasts themselves.
These represent the three basic deformational modes of strain on an elastomer.
The stress fields and temperature in the surface layers calculated from experimental data for a workpiece restored by facing and for a coating strengthened by a ball roller show that combining highly intense thermal and deformational effects in the process of surface strengthening should cause specific changes in the kinetics of plastic deformation, while in the surface layer of the workpiece, both in the coating and beyond it, strengthening structures may be formed at a depth of 0.
The three speakers all agreed that the Mediterranean cultural relationships are going through critical times and are marked by various deformational reality-distorted visions, negative stereotypes and misconceived perceptions.
It is also called positional or deformational plagiocephaly.
Brandon, aged nine months, has a condition called deformational plagiocephaly, commonly known as flat-head syndrome.
