Theoretical approaches to the engagement with patients in case-management programmes and assertive outreach teams: A systematic review of the literature.

WHAT IS KNOWN ON THE SUBJECT?: It is generally accepted that all interventions carried out by mental health nurses involve engagement with the patient; this engagement is a process that is gradually constructed and is not immediate. In Spain during last decade, nurses working in assertive outreach teams have gradually replaced the traditional institutional setting in favour of environments that are more familiar to the patient. In contrast, when patients and nurses interact outside institutional settings, a new approach and skillset is required in order to adapt to the new environment.

Characterisation of cement pastes by inverse gas chromatography.

Two cement pastes, commonly used in concrete formulations, were characterised by IGC at 35-80 degrees C before and after coating with an epoxy resin and a hardener. The cements are mixtures of hydrates in various proportions, such as calcium silicate hydrate (CaO-SiO2-H2O) and calcium hydroxide Ca(OH)2. Apolar and polar probes were used to determine the dispersive and acid-base characteristics of the cement pastes.
