Are Midwifery Students Adequately Prepared For Vaginal Breech Birth In Clinical Practice?, Steffne Nel, Sadie Geraghty

Research outputs 2014 to 2021

While the value of the clinical skills and expertise required to enable safe vaginal breech birth remains high, midwives who possess these skills are becoming scarce. Additionally, for many midwifery students, vaginal breech birth is becoming somewhat of an elusive event, rarely experienced in clinical practice when completing their training. Not so long ago, this was a standard competency taught to and held by obstetricians and midwives alike, but for those in developed nations working within robust healthcare systems, the frequency of planned vaginal breech birth is on a downward trend, and this is reflected in midwifery educational curriculums.

Homogenization And Growth Behavior Of Second-Phase Particles In A Deformed Zr-Sn-Nb-Fe-Cu-Si-O Alloy, Liang-Yu Chen, Peng Sang, Lina Zhang, Dongpo Song, Yanqiu Chu, Linjiang Chai, Laichang Zhang

Research outputs 2014 to 2021

Homogeneous distribution of fine second-phase particles (SPPs) fabricated by cycles of deformation and annealing in zirconium alloys is a critical consideration for the corrosion resistance of fuel claddings. Different deformation degrees of zirconium alloys would result in distinctive microstructures, leading to a distinct growth of SPPs during subsequent annealing. Unfortunately, the homogenization and growth behavior of SPPs in deformed zirconium alloys have not been well studied. In this work, a β-quenched Zr–Sn–Nb–Fe–Cu–Si–O alloy was rolled and annealed at 580◦C or 680◦C. The morphologies, distributions, and sizes of SPPs resulting from the different processing procedures were investigated. A linear distribution of …

Impact Of Feature Proportion On Matching Performance Of Multi-Biometric Systems, Wencheng Yang, Song Wang, Guanglou Zheng, Craig Valli

Research outputs 2014 to 2021

Biometrics as a tool for information security has been used in various applications. Feature-level fusion is widely used in the design of multi-biometric systems due to its advantages in increasing recognition accuracy and security. However, most existing multi-biometric systems that use feature-level fusion assign each biometric trait an equal proportion when combining features from multiple sources. For example, multi-biometric systems with two biometric traits commonly adopt a 50–50 feature proportion setting, which means that fused feature data contains half elements from each biometric modality. In this paper, we investigate the impact of feature proportion on the matching performance of multi-biometric …
