In areas with rapidly changing loads of large magnitude, utility companies often experience large deviations in frequency and area control error. Inadvertent tie-line power flow also occurs. The purpose of this research is to examine the effects a large scale energy storage device has on the system response to a rapidly changing load. Two control areas connected by a tie-line are modelled and s...

From the dawn of time, the sharing of knowledge has been one of the main forces driving science and innovation. Yet in recent decades, a proprietary culture, which wrongly posits that all intellectual property must be restricted, has spread across the pharmaceutical industry and threatens to stall the engine that has given us so many valuable treatments. This paper argues that pharmaceutical co...

Periodic regeneration is crucial to creating or sustaining uneven-aged (UEA) stands of loblolly (Pinus tuedu L.) and shortleaf (p echinatu Mill.) pines. Although both species are shade intolerant, they have silvical characteristics that are conducive to natural regeneration in UEA stands. Their seed production is fairly consistent and good, and the wind-disseminated seeds are well dispersed thr...
