In this study, the combustion characteristics of pine needles, needle humus, and co-combustion these two types biomass with coal were compared. addition, optimization performance coal/humus was assisted through following studies: (i) coal/pine humus studied under four different oxygen concentrations (N2, 10%O2/90%N2, 20%O2/80%N2, 40%O2/60%N2); (ii) synergistic effect between during also investi...

The Objective of this paper is to test the consequences of changes in health status of future cohorts of French elderly on healthcare expenditures. We value the precise effect of epidemiological and life expectancy changes on health expenditures for 2025 by using a markovian microsimulation model for a representative database of the contemporary cohorts in France. The originality of these simul...

abstract this paper proposes an approach to find an optimum structure for educational levels of human forces. to this end, a linear programming (lp) model integrated with a social accounting matrix (sam) was employed. the integrated model was employed using the sam of golestan province of iran. it was demonstrated that when unemployment is the result of inconsistency between supply and demand f...

Theoretical fluid flow models are used regularly to predict and analyze porous media flow but require verification against natural systems. Seismic monitoring in a controlled laboratory setting at a nominal scale of 1:1000 in the acoustic frequency range can help improve fluid flow models as well as elastogranular models for uncompacted saturated–unsaturated soils. A mid-scale sand tank allows ...
