TL;DR: In this paper, a new approach has been developed to predict a particle structure parameter used in the random pore model used to predict reactivity of bituminous coal chars with a strongly non-uniform porous structure.

TL;DR: A prairie dog (Cynomys ludovicianus) colony with a known history of habitation was studied to quantify the effects of herbivory on plant species composition, dominance, stature and diversity in a North American mixedgrass prairie.
Abstract: A prairie dog (Cynomys ludovicianus) colony with a known history of habitation was studied to quantify the effects of herbivory on plant species composition, dominance, stature and diversity in a North American mixedgrass prairie. Gradient analysis was used to quantify the relationship between plant community structure, prairie dog density, burrow density and habitation history and to document community-level responses of plants subjected to heavy grazing pressure. The results quantify the type, rate and extent of change which plant populations and communities may undergo in response to the differential grazing of plants variously tolerant of defoliation.

TL;DR: In this article, the shrinkage and electrical conductivity of coal ash were examined with laboratory ash prepared at about 800°C in crucibles, as well as combustion ash sampled from power stations.

TL;DR: In this article, a full AC formulation of the reactive power margin problem is presented, which is solved using an interior point implementation of the Newton method developed for the optimal power flow.
Abstract: Power system reactive power planning requires the computation of the reactive power margin from the point of voltage collapse in the steady-state in order to quantify the adequacy of the level of installed reactive power plant. This reactive margin is the difference between the maximum reactive load distributed across selected power system nodes and the reactive load at the planned system operating point. The margin can be estimated by applying an optimisation method using the total reactive load as the objective, with the load flow equations as equality constraints, whilst including system limits such as generator reactive capability limits as inequality constraints. This paper describes a full AC formulation of the optimisation problem. It is solved using an interior point implementation of the Newton method developed for the optimal power flow. This avoids potential difficulties in identifying the binding inequality constraints.
