Delivery Room Research: When Does Poor Quality Evidence Become an Ethical Issue?

Abstract: The November 2014 Ethics Rounds questioned: “When is waiver of consent appropriate in a neonatal clinical trial?” As neonatal clinical trialists, we believe that a waiver of prospective informed consent is often required and ethically appropriate to conduct scientifically rigorous delivery room clinical trials. As Drs Wootton, Arnold, and Tyson acknowledged, many emergency therapies have never been rigorously studied. Neonatal resuscitation medicine is especially bereft of high-level evidence. Only 23 of 157 (15%) publications cited in the 2010 ILCOR statement on neonatal resuscitation were randomized trials or meta-analyses of trials … E-mail: foglia{at}email.chop.edu

Effect of molybdenum on the resistance to H2S of high sulphur microalloyed steels

Abstract: The resistance to hydrogen sulphide of microalloyed steels with sulphur levels around 0.02% and containing copper, chromium, nickel and molybdenum was studied. The sulphide stress cracking (SSC), hydrogen induced blister cracking (HIBC), hydrogen embrittlement (HE) and corrosion rates of the steels were evaluated. The threshold stress during SSC testing was found to increase with an improvement in HE resistance. Molybdenum was found to improve the HE resistance which increases the SSC resistance. HIBC and corrosion rates were lowest at 0.3% molybdenum content in the steel. Additions of copper, chromium and nickel to a 0.3% molybdenum bearing steel enhance the resistance to SSC, HIBC and HE and corrosion rates. Fine precipitates 10–25 nm in size, containing molybdenum, titanium, vanadium, chromium and sulphur, uniformly distributed in the matrix were found to improve the sour gas resistance. Without molybdenum coarser precipitates 150 nm in size were observed and HIBC was found to initiate at such precipitates. Steel with low sulphur content (0.015%) but with coarser precipitates did not show any improvement to sour gas resistance when compared with a steel with high sulphur (0.028%) content, but possessing fine precipitates.
