The analysis of value chains has augmented our knowledge on the complexities, inter-linkages, distributional benefits, and institutional arrangements of production and marketing channels in developing countries. However, the analysis remains relatively qualitative and case-specific, with limited ability to rank or assess the impact of alternative(More)
The main objective of this study was to build several full-scale biosand filters (BSFs) and assess the long-term (9 month) efficacy for particulate and Escherichia coli removal under simulated real-world usage. Four replicates of three different filter designs were built: the traditional concrete BSF and two scaled-down versions that use a 5 or 2 gal bucket(More)
Alex Byrne (2005; 2011a; 2011b; 2011c and 2012) offers a novel interpretation of the idea that the mind is transparent to its possessor, and that one knows one’s own mind by looking out at the world. This paper argues that his (2011c and 2012) attempts to extend this picture of self-knowledge force him to sacrifice the theoretical parsimony he presents as(More)
The software SOLSCALE was developed to predict calcium carbonate scaling in solar domestic hot water (SDHW) systems. It requires inputs of make-up water chemistry, system design specifications, water demand, and location. Scaling predictions are based on an equilibrium water chemistry model and a system operating temperature model. The equilibrium water(More)
