Disturbing forest disturbances
The Forestry Chronicle, 2005 The forest sector in Canada makes a significant contribution to the wealth of the nation. Many of our forest ecosystems, like the phoenix, need fire for rebirth and renewal. In contrast, other forests rely on a cool, wet disintegration driven by insects and their commensal fungi feeding on trees to effect this renewal.

The Weather Conditions for Desired Smoke Plumes at a FASMEE Burn Site
Atmosphere, 2018 Weather is an important factor that determines smoke development, which is essential information for planning smoke field measurements. This study identifies the synoptic systems that would favor to produce the desired smoke plumes for the Fire and Smoke

Survey to Evaluate Escape of Eucalyptus spp. Seedlings from Plantations in Southeastern USA
International Journal of Forestry Research, 2013 Interest in biomass-based energy in the southeastern Unites States has led to increased need for fast-growing tree species. Several Eucalyptus species exhibit characteristics that make them attractive in the bioenergy context. However, some of these also

Winter Climate Variability, De-Icing Salt and Streetside Tree Vitality
Frontiers in Ecology and Evolution, 2022 De-icing salts are applied to roads and walking surfaces to mitigate winter hazards resulting from ice, snow and freezing rain. The vitality of streetside trees, especially those growing in densely built urban areas, is compromised by repeated exposure ...

Disturbed families, or families disturbed? [PDF]
British Journal of Psychiatry, 2004 Parents frequently perceive themselves as responsible for their child’s eating disorder. Clinicians who have observed a family’s overinvolvement with an ill, underweight child may readily subscribe to this view.

Invasion of a Legume Ecosystem Engineer in a Cold Biome Alters Plant Biodiversity
Frontiers in Plant Science, 2018 Plant ecosystem engineers are widely used to combat land degradation. However, the ability of those plants to modulate limiting abiotic and biotic resources of other species can cause damage to ecosystems in which they become invasive.

Ecosphere, 2021 Ecosystem process models can be used to predict forest response to disturbances at a range of scales. Selection of the spatial class of model should depend on the scale of the research or management question, and model type should depend on the ecosystem

, 2020 Disturbance observer is an inner-loop output-feedback controller whose role is to reject external disturbances and to make the outer-loop baseline controller robust against plant's uncertainties. Therefore, the closed-loop system with the DOB approximates the nominal closed-loop by the baseline controller and the nominal plant model with no ...

Disturbance-Disturbance uncertainty relation: The statistical distinguishability of quantum states determines disturbance [PDF]
Scientific Reports, 2018 AbstractThe Heisenberg uncertainty principle, which underlies many quantum key features, is under close scrutiny regarding its applicability to new scenarios. Using both the Bell-Kochen-Specker theorem establishing that observables do not have predetermined values before measurements and the measurement postulate of quantum mechanics, we propose that ...
