Redefining innovation processes: The digital designers at work

As design in digital innovation has become a thing, we highlight the inconclusive concepts that describe design activity in innovation processes. Proposing an alternative theoretical lens - a sociomaterial practice lens - we claim that this view can reveal the contribution of digital designers to the work of innovation. This paper draws on a research study with digital designers in the UK. At the same time as we begin to reconceptualise the ways digital design activity can be described, we also illustrate a theoretical framework based on 1) action and knowing as ordered by collectively produced objects, 2) sociomateriality and the configuration of human bodies and materials in action, 3) the co-emergence of objects and sociomaterial configurations where each is the condition of the other. This alternative way of looking at design activity may pose some challenges to the theoretical traditions in the field. We however believe that it contains immense potential too

The effect of water, brine and ethanol flotation on the quality and shelf life of macadamia kernels - 1. Whole kernels

Whole macadamia kernels were immersed in water (specific gravity 1.00 g/cm(3)), brine (SG 1.02 g/cm(3)) and ethanol solution (SG 0.97 g/cm(3)) for 30 or 60 s, re-dried to 1.0-1.5% moisture (wet basis) and stored under vacuum for 0, 4 and 12 months. Immersion in water had no effect on the quality or shelf life of kernels, as measured by sensory evaluation and analysis of the kernel oil. Immersion in brine and ethanol solutions changed the flavour of kernels, but had no effect on shelf life or kernel oil stability over 12 months storage. Water flotation to separate kernels based on differences in oil content is therefore feasible, but microbiological concerns need to be investigated

CO2 storage potential of the Middle Buntsandstein Subgroup - German sector of the North Sea

Highlights • Mapping of CO2 storage sites in the Buntsandstein subgroup in the exclusive economic zone of the German North Sea. • Static CO2 storage capacity estimation via Monte Carlo simulations. • Evaluation of individual storage sites in terms of structural complexity and compartmentalisation. Abstract The storage of CO2 in deeply buried geological formations provides a contribution to mitigate hard-to-abate CO2 emissions from industry. Robust geological models and capacity estimations are crucial for the successful planning and implementation of safe storage projects. This study focuses on the CO2 storage potential of the Middle Buntsandstein Subgroup within the Exclusive Economic Zone of the German North Sea. We have mapped a total of 71 potential storage sites based on existing 3D models, seismic and well data. Static CO2 capacities are calculated for each structure using Monte Carlo simulations with 10,000 iterations to account for uncertainties. All potential reservoirs are evaluated based on their potential capacity, burial depth, top seal integrity and trap type. We have identified 38 potential storage sites with burial depths between 800 m and 4500 m, reservoir capacities (P50) above 5 Mt CO2 and suitable sealing units. The estimated cumulative static storage capacity percentiles of these structures range between P10 = 902.08 Mt and P90 = 5508.93 Mt, with P50 = 2554.10 Mt. We expect the best storage conditions on the West Schleswig Block, where salt-controlled anticlines with moderate burial depths, large reservoir capacities and limited lateral flow barriers are the dominant trap types. Relatively poor storage conditions can be expected for small (P50 4500 m) and structurally complex potential storage sites in the Horn and Central Graben. Our study highlights the most prolific reservoirs and discusses the most suitable locations for further exploration
