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...

Silage is a common way of storing and feeding forage in the United States. There are 4 phases (aerobic, anaerobic, stable, and feedout) that silage undergoes. The most critical phases to manage to minimize nutritive losses are when the silage is going from an aerobic to an anaerobic environment and at feedout. The first important step in achieving silage of high nutritive value is to harvest at...

Enterprises are increasingly using a wide range of heterogeneous information systems for executing and governing their business activities. Even if the adoption of service orientation has improved loose coupling and re-usability, applications are still isolated data silos whose integration requires complex transformations and mediations. However, by leveraging Linked Data principles those data ...

Delivering sustainable development requires effective management of social, environmental and economic aspects of land. Historically, land administration systems have contributed to this by recording and organising interests in land, primarily through land registration, land mapping, land valuation and land development subsystems. Unfortunately these subsystems have established diversified serv...

Vertical silos are large cylinders used for material storage in agriculture and mineral industries. One of the silo problems is its obstruction due to dome and dense packing. Depend on the material properties and silo dimensions several techniques are used to solve this problem. In the present work, possibility of obstruction solution of a laboratory silo by ball impact is investigated. Test ma...

The paper covers the principles and design aspects of cylindrical bins for the storage and reclaimation of bagasse. The system described (fig. 1) was originally designed and drawn up by the author in 1963 for the Mossman sugar mill. The design was not adopted, favour being given to the more conventional rectangular system with travelling suspended reclaimer. The first circular system, with a ca...

The problem of determining the steady state flow of granular materials in silos under the action of gravity is considered. In the case of a Mohr-Coulomb material, the stress equations correspond to a system of hyperbolic conservation laws with source terms and boundary conditions. A higher order Discontinuous Galerkin method is proposed and implemented for the numerical resolution of those equa...
