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 ...

A laboratory silo trial, two lamb metabolism trials and a lamb growth trial were conducted to compare the nitrogen (N) value of swine methane digester effluent (MDE) to that of urea. Using laboratory silos (four/treatment), fermentation characteristics were measured for silages containing cracked corn, ground wheat straw and MDE added at levels of 0, 4, 8 or 12% of silage dry matter (DM). Lacti...

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...

Polyphenol oxidase (PPO) is predominately associated with the detrimental effect of browning fruit and vegetables, however, interest within PPO containing forage crops (crops to be fed to animals) has grown since the browning reaction was associated with reduced nitrogen (N) losses in silo and the rumen. The reduction in protein breakdown in silo of red clover (high PPO forage) increased the qu...

The advantages of metal silos in comparison with reinforced concrete are given. Types depending on a wall design considered. construction steel spiral-fold and the method forming cylindrical body general silo is illustrated. Features folding lock, its geometry location described. specifics silo, which affects their stress-strain state, analyzed. Listed two calculation schemes silо complexity in...
