ABSTRACT
The objective of this study was to determine if biochar yield could be increased by the deposition of volatile pyrolysis species within the bed during production, without negatively influencing the microporosity and adsorption properties. Aspen (Populus tremuloides) wood chips were loaded into three vertically stacked zones within a reactor and heated in nitrogen to temperatures between 420 and 650°C (i.e., pyrolyzed). The yield did increase from the zone at the reactor inlet to the subsequent zones as volatile species deposited and carbonized, and importantly, the carbonized deposits had a similar microporous structure and organic vapor uptake (1,1,1,2-tetrafluoroethane) to that of the primary biochar. Based on these results, bio-oil from previous runs at 600°C was recycled to the bed, which further increased the yield while maintaining the desirable adsorption properties of the biochar.

For the past decade nurse education has incorporated service user and carer perspectives into their programme and research agendas. Moving from rhetoric to the reality of embedding adult service user and carer knowledge into nurse education this paper discusses how this good practice was extended to young people under the age of 18. Globally, the mental health of young people is coming under the spotlight and based on this two "World Café" events focusing on young people and their mental well being were organised. Targeting a multi-agency audience the aim was to develop a partnership consortium, bringing together local organisations involved in promoting the mental well being of young people. This paper reports on the first World Café, led by two local young people's groups, 'Florescent Adolescent' and 'Vocal'. Following the presentations four important areas were identified (1) Inclusive rather than exclusive (2) Crystal ball gazing--young people's futures (3) A hole in the net--catching young people at the right time (4) Exposing the hidden agenda. The day resulted in three collaborative research proposals and the realisation that young people need opportunity to participate through utilising more innovative ways of engaging with the professional adult world.

This article seeks to explore the centrality and reality of partnerships or partnership working in current British social policy. The article will investigate the rhetoric and reality of partnerships using research based on the Early Years Development and Childcare Partnerships (EYDCPs) as an exemplar to critically question whether partnerships have become more pretence than panacea? In so doing the article will suggest that partnerships are deserving of greater critical analysis and research as their rhetorical force potentially represents another metaphor for social control.
