Sewage sludge may pose a fire risk. The safe storage of biomass waste is challenge due to self-heating processes. This study aims assess the propensity spontaneously combust sewage in order determine and transport conditions. evaluation spontaneous ignition hazard was assessed according EN 15188, by determination self-ignition temperature. Certain parameters assumed affect inclination self-igni...

We study the nearest neighbors one dimensional uniform q-model of force fluctuations in bead packs [Coppersmith et al (1996)], a stochastic model to simulate the stress of granular media in two dimensional silos. The vertical coordinate plays the role of time, and the horizontal coordinate the role of space. The process is a discrete time Markov process with state space R{1,...,N}. At each laye...

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...

This supplement engages some of the leading health economists in Europe to analyze how the policies in their respective health-care systems to control and influence pharmaceutical spending are likely to influence the overall performance of their systems, with respect to both cost control and the production of population health. Six countries were selected to provide a representative mix of publ...
