Brazilian Cinema at the Berlin International Film Festival
Research in Film and History, 2019 Film scholar Marijcke de Valck argues that film festivals “are sites of passage that function as the gateways to cultural legitimation” (2007: 38). More recently, Andreas Kötzing and Caroline Moine have pointed out the political dimensions of these ...

Impacts of geopolitics and policy on Latin American biodiversity and water resources
Agribusiness, EarlyView.Abstract Latin America is a major agricultural producer with important natural resources. Efforts have been made to protect sensitive areas but are hindered by agricultural trade disruptions outside the control of individual countries due to globally integrated crop markets.

Rho meson form-factors in the null-plane phenomenology [PDF]
International Workshop on Hadrons Physics 96, Topics on the
Structure and Interaction of Hadronic Systems, Brazil, 2001 The constituent quark rho meson electromagnetic form-factors are calculated, with covariant and null-plane approaches with the same model. The null-plane formalism produces the breakdown of the rotational symmetry for the one-body current operador, wich is investigated by comparing the numerical results in both approaches.

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

Non-Parallel Electric and Magnetic Fields in a Gravitational Background, Stationary Gravitational Waves and Gravitons [PDF]
arXiv, 2000 The existence of an electromagnetic field with parallel electric and magnetic field components in the presence of a gravitational field is considered. A non-parallel solution is shown to exist. Next, we analyse the possibility of finding stationary gravitational waves in nature. Finally, we construct a D=4 effective quantum gravity model.

Agribusiness, EarlyView.ABSTRACT The penetration of information and communication technologies (ICTs) in farming communities is increasing the use of smartphone‐based instant messaging apps. Despite this, the reasons behind participation and the impact on farm productivity in developing countries remain unexplored.

Non Parallels Electric and Magnetic Fields in a F.R.W. Cosmology. Classical and Quantum Gravitational Implications [PDF]
arXiv, 2000 At first, we discuss parallels electric and magnetic fields solutions in a gravitational background. Then, considering eletromagnetic and gravitational waves symmetries we show a particular solution for stationary gravitational waves. Finally we consider gravitation as a gauge theory (effective gravitational theory), evaluate the propagators of the ...
