Non-locality and Intermittency in 3D Turbulence
Numerical simulations are used to determine the influence of the non-local and local interactions on the intermittency corrections in the scaling properties of 3D turbulence.

Small-Scale Cosmology Independent of the Standard Model
‘Small-scale cosmology’ is a theory designed to incorporate the linear redshift versus distance relation, which is inferred from observations, into the theoretical framework independent of the global Robertson–Walker–Friedman (RWF)-type models.

Structures, actors, and interactions in the analysis of natural resource conflicts
We propose a research approach to natural resource conflicts that includes different tempos of the developments that lead to a conflict becoming manifest. This approach can help to distinguish dimensions of the conflict and to understand the logic behind

Modeling of a Small-scale Biomass Updraft Gasifier
Biomass can be efficiently transformed into valuable gas products via gasification. Gasification converts biomass through partial oxidation into a gaseous mixture, small quantities of char and condensable compounds. In this work, an updraft gasifier is regarded because the updraft gasifier is suitable for wet fuels such as agricultural residues ...

Evaluating vibrations on a small-scale model of a timber footbridge
In Brazil, the study of pedestrian-induced vibration on footbridges has been undertaken since the early 1990s, for concrete and steel footbridges. However, there are no recorded studies of this kind for timber footbridges.

A turbulence-driven model for heating and acceleration of the fast wind in coronal holes [PDF]
A model is presented for generation of fast solar wind in coronal holes, relying on heating that is dominated by turbulent dissipation of MHD fluctuations transported upwards in the solar atmosphere.
