Collaborative innovation is increasingly put forward as a way of addressing the many wicked problems our society faces today. This article focuses on how politicians indirectly affect projects of collaborative innovation and whether stakeholders experience them as helpful or hindering to the project. The impact of politicians on projects of collaborative innovation are compared across four cases and throughout three project phases (set-up, ...

Modern distribution networks are rich in distributed energy resources (DERs) but old in terms of infrastructure and management mentality. This has led to their experiencing more frequent operational issues, leading to distribution system operators (DSOs) facing a key question: should they reinforce or resort to local flexibility markets to solve their issues? The decision ultimately boils down to what the cost of flexibility and value of the ...

Conventional ceria-stabilized tetragonal zirconia (Ce-TZP) with modest flexural strength has rarely been used as compared to yttria-stabilized zirconia, even though it has excellent hydrothermal stability and high toughness. Ce-TZP-based composites were recently developed, being tough and remarkably in combination with transformation-induced plasticity. However, distinct from the widely applied composite approach to improve the strength of ...

During the atmospheric entry phase at hypersonic speed, the radio communication from/to a space vehicle can be disrupted due to the formation of a plasma sheath within the surrounding flow field. In order to characterize such communication blackout phases, this work presents a numerical methodology combining Computational Fluid Dynamic (CFD) simulations of ionized chemically reacting entry flows by means of Computational Object-Oriented ...

The health-beneficial long-chain omega-3 polyunsaturated fatty acids (n-3 LC-PUFA) are easily affected by the undesired process of lipid oxidation in fish oil, while being stable in the lipid extracts of photoautotrophic microalgae. The current research investigates the role of carotenoids by evaluating the oxidative stability of mixtures of fish oil with total lipid extracts of two different microalgae (Phaeodactylum and Isochrysis) throughout ...

OBJECTIVES: Combined biliary obstruction and gastric outlet obstruction (GOO) represent a challenging clinical scenario despite developments in therapeutic endoscopic ultrasonography (EUS) as GOO might impair EUS-guided biliary drainage. Little is known about the effectiveness of different therapeutic combinations used to treat double obstruction, especially regarding stent patency. METHODS: All consecutive patients with double obstruction ...
