The Bitter Taste of Brazil's Temporary Import Ban on Robusta Coffee
Agribusiness, EarlyView.ABSTRACT Brazil, a leading Robusta coffee producer and exporter, faced a significant drought in 2016–2017, which drastically reduced production and depleted stocks. Consequently, Brazil temporarily permitted the import of one million 60‐kg bags of Robusta coffee in the spring 2017. An import ban was imposed shortly afterward due to lobbying by domestic

Singularities of axisymmetric free surface flows with gravity [PDF]
arXiv, 2012 We consider a steady axisymmetric solution of the Euler equations for a fluid (incompressible and with zero vorticity) with a free surface, acted on only by gravity. We analyze stagnation points as well as points on the axis of symmetry. At points on the axis of symmetry which are not stagnation points, constant velocity motion is the only blow-up ...

Stagnation point reverse flow combustor [PDF]
, 2008 A method for combusting a combustible fuel includes providing a vessel having an opening near a proximate end and a closed distal end defining a combustion chamber. A combustible reactants mixture is presented into the combustion chamber. The combustible

Regulating Airflow Using Hybrid LCN for Soft Pneumatic Circuits
Advanced Intelligent Systems, EarlyView.To address more autonomous soft robots with embodied control and regulation systems, herein, a liquid crystal network‐based fluid regulator that can be manipulated through multiphysical stimuli is proposed. Aided by finite element modeling for thermal actuation, regulators are designed and incorporated into fluidic circuits and demonstrate that they ...

Quantitative determination of the leaching range of in-situ leaching mining area by stagnation point
Nuclear Engineering and TechnologyThe leaching range is critical to the leaching efficiency, production cost and environmental effect of in-situ leaching of uranium. In this study, the groundwater dynamics of the well-site was simulated to determine the leaching range in condition of ...

“Who's breaking the law … not us, them!”: Inside immigration detention in Portugal
American Journal of Community Psychology, EarlyView.Abstract In this paper, we examine immigration detention in Portugal, a system whose daily operations and inherent violence are overlooked in both public and academic discourses. Even within community psychology, discussions on immigration detention have largely remained on the fringes of scholarly debates. Guided by a justice‐centered ecological lens,
