We investigate experimentally the discharge of a 2D-silo, Hele-Shaw cell, filled with mono layer ferromagnetic grains submitted to an external magnetic field B perpendicular cell plane. In this case pair interactions are repulsive. show that granular flow rate decreases systematically amplitude applied. Interestingly, while output remains constant during experiment, we reveal very large spatio-...

Many informational web search queries seek information about named entities residing in structured databases. The information about entities that a user is seeking could be available from the structured database, or from other web pages. For example, consider an informational query such as [lowlight digital cameras]. A large structured database consisting of products may contain several product...

We present the results of both experimental and numerical investigations silo discharge for a cohesive granular material. In our study, thanks to cohesion-controlled material (CCGM) we propose investigate effect length l c , on two different configurations, one axisymmetrical, quasi-2D rectangular silo. an adjustable bottom is used control size orifice. As observed cohesionless by previous stud...

CONTEXT Anthropogenic vectors enhance the natural dispersal capacity of plant seeds significantly in terms of quantity and distance. Human-mediated seed dispersal (i.e. anthropochory) greatly increases the dispersal of crop species across agroecosystems. In the case of oilseed rape (OSR), spillage of seeds from grain trailers during harvest has never been quantified. METHODS Our experimental ...

Jiang, S., Barber, E.M., Meiering, A.G. and Jofriet, J.C. 1991. Toxic gas production and silo ventilation. Can. Agric. Eng. 33:151-159. Equations were developed to predict the minimum safe duration of ventilationrequired in tower silos to reduce carbon dioxide and oxides of nitrogen to safe limits for human entry into the silo. Unlike previous analyses, the model developed in this paper account...
