The aim of this study was to compare different fetal growth curves in twin pregnancies with severe placental insufficiency. A retrospective cross-sectional analysis of 47 twin pregnancies with absent or reverse end diastolic flow in the umbilical artery of one fetus was performed. Pregnancies with major fetal abnormalities, twin-twin transfusion or three or more fetuses were not included. The e...

This study studies the torsional capacity of rectangular ultra-high-performance-concrete (UHPC) beams. Nine UHPC beams were tested under pure torsion load. The failure modes presented and influences parameters, including reinforcement ratio, stirrup ratio steel fiber content discussed. experimental results showed that longitudinal had little effect on crack width plastic stiffness in serviceabi...

The TATA binding protein (TBP) and transcription factor IIB (TFIIB) play crucial roles in transcription of class II genes. The requirement for TBP-TFIIB interactions was evaluated in maize cells by introducing mutations into the Arabidopsis TBP (AtTBP2) within the C-terminal stirrup. Protein binding experiments indicated that amino acid residues E-144 and E-146 of AtTBP2 are both essential for ...

As a new member of concrete-filled steel tube (CFT) structural families, elliptical tubes (CFETs) have great potential to be used as piers and columns in bridges airport terminals because its low flow resistance coefficient reasonable distribution major–minor axis. Hence, the main objective this paper presents an experimental investigation on seismic behavior terminal stirrup-confined (TS-CFET)...
