Cyclic crushing experiments with a haversine velocity waveform were performed on passively confined, freshwater columnar ice specimens for variety of velocities and frequencies. The aim the was to study deformation failure behavior in when loaded at predefined displacement pattern closely resembling frequency lock-in regime ice-induced vibrations. focus development load grain specimen scales du...

Using data from the child supplement of the US National Longitudinal Survey of Youth, and fitting three-level random-effects models of child health and cognitive development, we test whether left-handed children have different outcomes from those of their right-handed counterparts. The health measures cover both physical health and mental health, and the cognitive development test scores span v...

Overpressurization blast (OB) exposure used to induce traumatic brain injury (TBI) in the rodent model can result in somatomotor and behavioral changes. Increased anxiety is evidenced after OB TBI in Dorsal and Frontal blast-wave exposed injured animals. Sustained impaired somatosensory functions occur after multiple OB injuries in Dorsal animals. Somatomotor function is impaired acutely but pa...

Injury due to stroke and traumatic brain injury result in significant long-term effects upon behavioral functioning. One central question to rehabilitation research is whether the nature of behavioral improvement observed is due to recovery or the development of compensatory mechanisms. The nature of functional improvement can be viewed from the perspective of behavioral changes or changes in n...

Sintering is a method that makes powdered materials (such as fine ore or preparation concentrate) into block mass under conditions involving incomplete fusion by heating to high temperature. Its production is sinter which is irregular and porous (FU et al., 1996). The following parts are usually included in sintering process: acceptance and storage of iron-containing raw materials, fuel and flu...

It is shown that the initial singularities in spatially compact spacetimes with spherical, plane or hyperbolic symmetry admitting a compact constant mean curvature hypersurface are crushing singularities when the matter content of spacetime is described by the Vlasov equation (collisionless matter) or the wave equation (massless scalar field). In the spherically symmetric case it is further sho...

Gradient distribution of vascular structure made the bamboo wall so effective which improved load-bearing capacity such bio-mimicked energy absorption structures and modify crush behavior thin-walled composite tubes. In this research, influence layering design stacking sequence on behavior, failure mechanism absorbed bamboo-inspired GFRP tubes is assessed experimentally numerically. Quasi-stati...
