Views and practice of abortion among Queensland midwives and sexual health nurses.

Background: A significant barrier to the access of safe abortion is the lack of trained abortion providers. Recent studies show that with appropriate education, nurses and midwives can provide abortions as safely as medical practitioners.

Aims: To examine the attitudes and practices of registered midwives (RMs) and sexual health nurses (SHNs) in Queensland toward abortion.

Effect of nanocomposite synthesis on the combustion performance of a ternary thermite.

Nanocomposite thermites are attractive materials for their diverse applications from metallurgy to ordnance technologies. While there are a plethora of combinations of fuel and oxidizers, this work shows that the composite's overall performance is intimately tied to how the fuel and oxidizer are prepared and combined. Comparison of the combustion velocities of two separate ternary mixtures of Al-Fe(2)O(3)-SiO(2), one prepared in situ using sol-gel processing and the other prepared by physically mixing discrete nanoscale particles, demonstrated different burning behaviors as a result of preparation technique.
