Offshore work and the work of nurses on board: an integrative review

OBJECTIVETo know the production of theoretical approaches on issues related to offshore work and the work of offshore nurses.METHODIntegrative literature review conducted in the databases of LILACS, BDENF, MEDLINE, SciELO and Index PSI.RESULTSWe selected 33 studies published in national and international journals between 1997 and 2014. The thematic analysis corpus resulted in four central themes: offshore work environment; amid work adversities, an escape; structuring of offshore health and safety services; in search of safe practices.CONCLUSIONThis study contributes to the offshore work of nurses in relation to the nature of work, acting amid adversities and the restless search for safe practices in the open sea.

Remoção do íon amônio de águas produzidas na exploração de petróleo em áreas offshore por adsorção em clinoptilolita

This work describes the use of clinoptilolite for removal of ammonium ions present in waters produced at the Campos' Basin. Samples were previously treated in order to remove organic compounds and metals. Experiments were run in fixed- and fluidized-bed systems, at room temperature. The fluidized-bed systems did not remove efficiently the ammonium ion. The best operational conditions were obtained with clinoptilolite particle size in the range 0.30-0.50 mm, under ascendant flow (3 mL min-1), in a fixed-bed system. The best zeolite performance was found when it was pretreated with 0.5 mol L-1 NaOH. Na+ was the most important interfering ion due to its high concentration in the water. Clinoptilolite lost partially its capacity to retain ammonium ions after several regeneration cycles with NaOH.
