Sixteen large-scale reinforced concrete specimens without web reinforcements were tested to study the behavior of typical bridge piers subjected to deflection reversals that were large enough to cause extensive yielding of the longitudinal reinforcement. The different parameters considered included shear spanto-depth ratio, percentage of longitudinal reinforcement, frequency of the applied load...

BACKGROUND Unexpected clinical deterioration before 34 weeks gestation is an undesired course in early-onset pre-eclampsia. To safely prolong preterm gestation, accurate and timely prediction of complications is required. METHOD Women with confirmed early onset pre-eclampsia were recruited from 53 maternity units in the UK to a large prospective cohort study (PREP-946) for development of prog...

Concrete-filled steel tubular Y-shaped (CFST-Y) piers are good candidates for meeting the structural and aesthetic requirements of bridges. By using theoretical nonlinear static (pushover) analyses, seismic performances three types CFST-Y were evaluated at different hazard levels. The formulas first proposed to estimate lateral stiffnesses with pier–deck connections. Then, ductility development...

pardon. The document is, after all, sent by Truth, the divine authority whose tower overshadows the fair field. Its message "Et qui bona egerunt ibunt in vitam eternam; / Qui vero mala in ignem eternum" is an article of the Athanasian Creed and thus an orthodox tenet of the faith. Moreover, critics who argue that Truth's document is a pardon maintain that its text is consistent with the theme o...

An attempt was made to develop a method for sizing stable riprap around bridge piers based on a huge amount of experimental data, which is available in the literature. All available experimental data for circular as well as round-nose-and-tail rectangular piers were collected. The data for rectangular piers, with different aspect ratios, aligned with the flow or skewed at different angles to th...

The bifunctional frustrated BH(-)/B hydridoborate nucleophile/borane Lewis acid pair 6 is prepared starting from the borata-diene 3 by a sequence of sequential protonation/hydride attachment, followed by hydroboration with Piers' borane [HB(C6F5)2]. The trans-1,2-bifunctional system 6 reduced carbon monoxide eventually to the aldehyde product 10.
