Background  Through play children exercise their emerging mental abilities, and for their part, when in collaborative play, caregivers often adjust their behaviours to assist their children's progress. In this study, we focused on comparisons between play of Down Syndrome (DS) children with their two parents as well as on comparisons between the two parents' play behaviours.Method  Altogether 40 parent–child dyads participated: 20 children with DS (M age = 36.14 months) with their mothers and separately with their fathers. We coded participants' play behaviours during child solitary and mother–child and father–child collaborative sessions.Results  Although children increased exploratory play from solitary to collaborative sessions with both parents, symbolic play increased only during joint play with fathers. Fathers displayed less symbolic and more exploratory activity compared to mothers. Mothers and fathers alike were attuned to their children, although fathers showed a higher degree of attunement.Conclusions  This study shows that maternal and paternal contributions to DS child play skills are positive but different. During collaborative play children received specific and nonoverlapping scaffolding from their two parents, and fathers' contributions were unique.

There is a need to better understand particle size distributions (PSDs) from turbulent flames from a theoretical, practical and even regulatory perspective. Experiments were conducted on a sooting turbulent non-premixed swirled ethylene flame with secondary (dilution) air injection to investigate exhaust and in-burner PSDs measured with a Scanning Mobility Particle Sizer (SMPS) and soot volume fractions (fv) using extinction measurements. The focus was to understand the effect of systematically changing the amount and location of dilution air injection on the PSDs and fv inside the burner and at the exhaust. The PSDs were also compared with planar Laser Induced Incandescence (LII) calibrated against the average fv. LII provides some supplemental information on the relative soot amounts and spatial distribution among the various flow conditions that helps interpret the results. For the flame with no air dilution, fv drops gradually along the centreline of the burner towards the exhaust and the PSD shows a shift from larger particles to smaller. However, with dilution air fv reduces sharply where the dilution jets meet the burner axis. Downstream of the dilution jets fv reduces gradually and the PSDs remain unchanged until the exhaust. At the exhaust, the flame with no air dilution shows significantly more particles with an fv one to two orders of magnitude greater compared to the Cases with dilution. This dataset provides insights into soot spatial and particle size distributions within turbulent flames of relevance to gas turbine combustion with differing dilution parameters and the effect dilution has on the particle size. Additionally, this work measures fv using both ex situ and in situ techniques, and highlights the difficulties associated with comparing results across the two. The results are useful for validating advanced models for turbulent combustion. ; European Union (EU), Horizon 2020 (H2020), Clean Sky 2 Joint Undertaking, Industrial Leadership (IL) (Project LEAFINNOX, grant number 831804)

As the annual production of carbon Dioxide (CO2) reaches 30 billion tones, the growing issue of the greenhouse effect has triggered the development of technologies for CO2 sequestration, storage and use as a reactant. Collecting together the reports of the Congress at University of Rome (Campus Bio-medico) held 16th April 2012, CO2: A Valuable Source of Carbon presents and discusses promising technologies for the industrial exploitation of CO2. Divided into two parts, the current technology is evaluated and summarized before European and national projects are presented. The focus on CO2 recovery, particularly in value-added production, proposes applicable methods to develop sustainable practices and even to mitigate greenhouse gas emission from large-scale fossil fuels usage. Including current data and real-world examples, CO2: A valuable source of carbon provides students, engineers, researchers and industry professional with up-to-date material and potential areas for development and research
