Dual differential interferometer

A dual two-beam differential interferometer that measures both the amplitude and orientation of propagating, broadband surface acoustic waves is disclosed. Four beams are focused on a surface. The four reflected beams are separated into two pairs. The two pairs are detected to produce two signals that are used to compute amplitude and orientation

Testing water-soluble carbohydrate QTL effects in perennial ryegrass (Lolium perenne L.) by marker selection

Water-soluble carbohydrates (WSC) are an important factor determining the nutritional value of grass forage and development of genetic markers for selection of WSC traits in perennial ryegrass would benefit future breeding programmes. Quantitative trait loci (QTLs) for WSC have been published for an F-2 ryegrass mapping family. Markers showing significant associations with these QTLs were used to design narrow-based populations with homozygosity for target QTLs. Founders were selected from within the mapping family. The divergent populations produced were analysed for WSC content in the glasshouse and the field. There was evidence of complex interactions between WSC content and other factors and traits, including the scale of assessment, time/degree of sward establishment and other forage quality parameters. Differences between the divergent pairs of the various populations were small. However, differences observed between the founder selection groups were maintained and the roles of the QTL regions in regulating forage WSC content were confirmed. In general, the individual divergent populations exploited only a limited extent of the large phenotypic variation available within the mapping family. However, this study sets the scene for exploring the opportunities for marker-assisted breeding strategies for complex traits in obligate out-breeding species, and the challenges of doing this are discussed

Introduction to macroscale scenario switching – from refined fuels to hydrogen in personal transport [Chapter 3]

This chapter introduces the core scenario for which potential economic impacts of hydrogen and fuel cells in the UK are considered in this White Paper. This focuses on the replacement of petrol and diesel in cars with hydrogen, with some attention to the manufacture and uptake of hydrogen-ready cars and short-term investment in activities such as Research and Development and construction required to enable such as switch

Employment [Chapter 6]

This chapter focuses on the employment embodied in the hydrogen supply chain activity implied by the headline input-output ‘multiplier’ values introduced in Chapter 3 and decomposed for output and total value-added (GDP) in Chapter 4. Here attention is on considering the composition of hydrogen supply chain multipliers in terms of the sectoral location of jobs and the associated generation of wage income. The latter gives some indication of the ‘quality of jobs’ associated with particular areas of the hydrogen economy. This is in so far as wage income is an element of value-added at the economy-wide level (GDP by an income measure) and to the individuals who receive earnings from paid employment. Given that jobs in the input-output framework are reported in full-time equivalent (FTE) units (for reasons of aggregation across sectors) it is not possible to consider the quality of jobs from a part-time vs. full-time perspective. However, Chapter 7 does go on to consider skills requirements, which is another important indicator of the quality of jobs/employment (and one that may, to some extent correlate with wage incomes)
