Two new types of solid silomne additives for plastics are described which give improved benefits compared to previous silicone additives. Ultra-high-molecularweight (UHMW) siloxanes are used in the new additives: traditional silicone plastic additives have used much lower molecular-weight silicones. The siloxane is converted into solid forms, either masterbatch pellets or powders, that are easy to feed, or mix, into plastics during compounding, extrusion, or injection molding.Ultra-high-molecular-weight siloxanes can be compounded into masterbatch pellets at higher siloxane concentrations than previously possible, e. g., up to 500h.They impart improved processing and release, lower coefficient of friction, and broader performance latitude compared to conventional lower-molecular-weight silicones. These benefits can be delivered at reduced siloxane levels with increased concentration at the surface interface with a new functionalized UHMW siloxane which provides unique surface segregation characteristics. Ultra-high-molecular-weight siloxanes have been formulated into powders that can also act as processing aids and mechanical property modifiers for highly filled polymers such as fire-retardant systems. This paper uses polyolefins as a model. However, many of the effects shown in polyolefins have also been seen in other resin systems.

Ecological psychologists and enactivists agree that the best explanation for a large share of cognition is non-representational in kind. In both ecological psychology and enactivist philosophy, then, the task is to offer an explanans that does not rely on representations. Different theorists within these camps have contrasting notions of what the best kind of non-representational explanation will look like, yet they agree on one central point: instead of focusing solely on factors interior to an agent, an important aspect of cognition is found in the link or coupling between an agent and the external world. This link is fluid, dynamic, and active in a variety of ways, and we do not need to add any internal extra something in the perception-action-cognition process. At the same time, even devout defenders of ecological psychology and enactivism recognize that plenty happens inside an agent during cognition. In particular, no one denies that the brain plays an important role. What, then, is the role of the brain if it's not in the game of representing the environment? One possible option is to describe the brain as a resonant organ instead of a representational organ. In this paper we consider the history of resonance in more detail. Particular focus will be placed on two different sets of approaches that have developed the concept of resonance: a representational reading of resonance and a non-representational, dynamic account of resonance. We then apply these accounts to a case study on music performance, specifically in the context of standard tonal jazz. From this application, we propose that a non-representational resonance account consistent with both enactivism and ecological psychology is a viable way of explaining jazz performance. We conclude with future considerations on research regarding the brain as a resonant organ.

Algebraic closures for the turbulent scalar fluxes were evaluated for a discrete hole film cooling geometry using the results from a high-fidelity large eddy simulation (LES). Several models for the turbulent scalar fluxes exist, including the widely used gradient diffusion hypothesis (GDH), the generalized GDH (GGDH), and the higher-order GDH (HOGGDH). By analyzing the results from the LES, it was possible to isolate the error due to these turbulent mixing models. Distributions of the turbulent diffusivity, turbulent viscosity, and turbulent Prandtl number were extracted from the LES results. It was shown that the turbulent Prandtl number varies significantly spatially, undermining the applicability of the Reynolds analogy for this flow. The LES velocity field and Reynolds stresses were fed into a Reynolds-averaged Navier–Stokes (RANS) solver to calculate the fluid temperature distribution. This analysis revealed in which regions of the flow various modeling assumptions were invalid and what effect those assumptions had on the predicted temperature distribution.

The conceptual resources of '4E' music cognitioni.e. the embodied, embedded, extended, and enactive paradigmshave offered a rich set of tools to explore the nature of musical experience. Among these four approaches, the extended mind perspective has heretofore received less overall attention. In this paper we focus on further developing the musically extended mind -especially in regards to musical performance -drawing on recent third wave developments. After exploring the main tenets of first wave (parity between internal and external components), second wave (complementarity between internal and external components), and third wave (dynamically changing internal and external components, as well as extended and decentralized agency) accounts of the extended mind, we turn to introducing existent first and second wave positions on music cognition. While they offer important insights, we suggest that elements of the third wave, especially focused on decentralized agency, are needed to capture the complexities of musical performance. We apply the third wave tools to the case of music performance in order to show, first, the specific limitations of the first two waves focus on parity and complementarity and, second, how a third wave account may be developed by applying it within this particular context.
