GASP: Guitars with ambisonic spatial performance
‘Guitars with Ambisonic Spatial Performance’ (GASP) is an ongoing project where our expertise in surround sound algorithmic research is combined with off-the-shelf hardware and bespoke software to create a spatial multichannel surround guitar performance system. This poster was funded through the ‘Undergraduate Research Scholarship Scheme’ (URSS) and presented at the University of Derby Buxton Campus 10th Annual Learning & Teaching conference on Wednesday 1st July 2015. The theme being ‘Students as Partners: Linking Teaching, Research and Enterprise’. The poster was also utilised as a contribution to the Creative Technologies Research Group (CTRG) ‘Sounds in Space’ symposium held at the University of Derby in June 2015, at which three pieces of multichannel guitar recordings were demonstrated.‘Undergraduate Research Scholarship Scheme’ (URSS) University of Derb
Duchy Originals Future Farming Programme – A practical, farmer led approach to innovation
We have adapted farmer field schools for the UK to boost innovation in organic and other low-input systems by encouraging farmers to share knowledge about experimentation and supporting farmer priorities for research. Benefits in productivity and for the environment come from improved management practices and the use of renewable resources to provide low cost and sustainable solutions
Rotating biological contactors for wastewater treatment - A review
Rotating biological contactors (RBCs) for wastewater treatment began in the 1970s. Removal of organic matter has been targeted within organic loading rates of up to 120 g m−2 d−1 with an optimum at around 15 g m−2 d−1 for combined BOD and ammonia removal. Full nitrification is achievable under appropriate process conditions with oxidation rates of up to 6 g m−2 d−1 reported for municipal wastewater. The RBC process has been adapted for denitrification with reported removal rates of up to 14 g m−2 d−1 with nitrogen rich wastewaters. Different media types can be used to improve organic/nitrogen loading rates through selecting for different bacterial groups. The RBC has been applied with only limited success for enhanced biological phosphorus removal and attained up to 70% total phosphorus removal. Compared to other biofilm processes, RBCs had 35% lower energy costs than trickling filters but higher demand than wetland systems. However, the land footprint for the same treatment is lower than these alternatives. The RBC process has been used for removal of priority pollutants such as pharmaceuticals and personal care products. The RBC system has been shown to eliminate 99% of faecal coliforms and the majority of other wastewater pathogens. Novel RBC reactors include systems for energy generation such as algae, methane production and microbial fuel cells for direct current generation. Issues such as scale up remain challenging for the future application of RBC technology and topics such as phosphorus removal and denitrification still require further research. High volumetric removal rate, solids retention, low footprint, hydraulic residence times are characteristics of RBCs. The RBC is therefore an ideal candidate for hybrid processes for upgrading works maximising efficiency of existing infrastructure and minimising energy consumption for nutrient removal. This review will provide a link between disciplines and discuss recent developments in RBC research and comparison of recent process designs are provided (Section 2). The microbial features of the RBC biofilm are highlighted (Section 3) and topics such as biological nitrogen removal and priority pollutant remediation are discussed (Sections 4 and 5). Developments in kinetics and modelling are highlighted (Section 6) and future research themes are mentioned

Water quality projects in North Dakota
AE-1069; Because water quality issues have been emphasized in
recent years, the NDSU Extension Service has gathered
information from various organizations about water quality
projects throughout the state. This document is the result
of that effort and is intended to be a basic reference for
people involved or interested in water quality issue
Ice Ice Maybe. Bacteria that trigger frost in grapes could also be responsible for forming raindrops in the atmosphere.
The freezing of a single young shoot in a vineyard would go unnoticed come harvest time. However, the subsequent frosting of hundreds of thousands more shoots later that night could wipe out the entire vintage. Likewise, the freezing of a single cloud droplet would have no impact on the weather. But the subsequent freezing of millions more in the same updraft could kick-start a thunderstorm. A causal agent in both scenarios may be, oddly enough, bacteria. That is, ice nucleation active (INA) bacteria, which, by freezing water at high temperatures, could be both triggering frost and making rain. The article gives an overview of current research into the behaviour and properties of ice nucleation active (INA) bacteria and the resulting effects of the bacteria on weather patterns in different climates across the world
Provincial and Territorial Interests in Land Use Planning and Development
Report: iv., pp.156, appendix A-G.; ill., digital file.Land use planning in Canada is in the process of undergoing a radical shift as legislation, much of
which dates from the 1980s or even the 1970s, is less and less able to cope with the increasing
complexity of land use issues faced in every region of the country. Growing metropolitan regions,
mechanization and intensification of farming practices and a growing concern over environmental
issues have radically altered the context within which planning takes place. Concerns with water
quality, particularly in light of the Walkerton tragedy, as well as the advent of Intensive Livestock
Operations and rapidly expanding urban fringes are at the fore of land use issues facing planners in
Canada today.The Intergovernmental Committee on Urban and Regional Researc
