Managing alcohol related aggression in the emergency department (Part II)

Violence in the emergency department (ED) is a global problem. In our first paper, we highlighted the potential psychological effects of alcohol intoxication, the literatures discussion of alcohol related violence in the emergency department and the importance of developing positive nurse/service user relationships. In this second paper, we discuss personal and organisational strategies clinical nursing staff may consider appropriate to minimise the risk of assault when caring for service users projecting alcohol related aggression.

Managing alcohol related aggression in the emergency department (Part 1)

Internationally, violence in the emergency department (ED) is of a constant concern to emergency practitioners. Frequently, both original research papers and anecdotal reports emphasise the phenomenon of alcohol related aggression in the ED. In this first paper, we highlight the literatures discussion of alcohol related violence in the emergency department and the potential psychological effects of alcohol intoxication. In the second we offer personal and organisational strategies clinical nursing staff may consider appropriate to minimise the risk of assault when caring for service users projecting alcohol related aggression.

Release kinetics of oleyl alcohol from a self-lubricating silicone biomaterial

The development of self-lubricating silicone elastomeric biomaterials, prepared using the novel crosslinking agent tetra( oleyloxy) silane and having very low coefficients of friction, has recently been reported. In this study, the in vitro release characteristics of lubricious oleyl alcohol produced during the silicone curing reaction have been quantitatively evaluated for a range of tetra( propoxy) silane/tetra(oleyloxy) silane crosslinker compositions using a novel evaporative light scattering detection method in combination with high performance liquid chromatography. The mechanism of oleyl alcohol release was seen to deviate from a simple, matrix-controlled diffusion process and instead obeyed an anomalous transport mechanism. An explanation for the observed release behaviour has been proposed based on competitive reaction kinetics between the tetra( oleyloxy) silane and tetra( propoxy) silane substituents of the silicone crosslinking agents.

Influence of Manufacturing Tolerance on Aircraft Direct Operating Cost (DOC)

The influence of manufacturing tolerance on direct operating cost (DOC) is extrapolated from an engine nacelle to be representative of an entire aircraft body. Initial manufacturing tolerance data was obtained from the shop floor at Bombardier Aerospace Shorts, Belfast while the corresponding costs were calculated according to various recurring elements such as basic labour and overtime labour, rework, concessions, and redeployment; along with the non-recurrent costs due to tooling and machinery, etc. The relation of tolerance to cost was modelled statistically so that the cost impact of tolerance change could be ascertained. It was shown that a relatively small relaxation in the assembly and fabrication tolerances of the wetted surfaces resulted in reduced costs of production that lowered aircraft DOC, as the incurred drag penalty was predicted and taken into account during the optimisation process.
