Therefore, the role of four strictly conserved histidine residues (His38, His361, His370, and His485) in the glucuronidation of 4-methylumbelliferone, as reporter substrate, was examined using site-directed mutagenesis. For this purpose, stable heterologous expression of wild-type and mutant UGT1A...
Wildland fire management strategy in the US and elsewhere has gradually shifted from total suppression of all wildland fire toward recognizing the role of fire as an essential ecological process with potential benefits to natural resources and human health under the right conditions (Stephens and Ruth2...
Prescribed fire in the interface: separating the people from the trees Land managers in Florida rely on prescribed fire to prepare sites for regeneration, improve wildlife habitats, reduce vegetative competition, facilitate timber management activities, and mitigate wildfire risk. More than one million ...
Prescribed fire, although having low intensity and being able to reduce the risk of wildfire may modify soil properties in the short term, with possible increases in runoff and erosion risk. Soil mulching with vegetation residues is one of the most common post-fire management strategies. Residues...
uses low-intensity fire on the ground (the understory) to remove excess vegetation (fuels) under specific environmental conditions with fire confined to a predetermined area. Understory burning produces fire behavior and fire characteristics required to attain planned fire and resource management ...
The underlying problem becomes even more challenging if the transient behavior also needs to be accommodated and only system output is available for feedback. Several key design innovations are proposed to circumvent the aforementioned technical difficulties, including the employment of state estimation ...
In addition, a unified performance analysis framework based on proof by contradiction and the barrier function is established to reveal the inherent robustness of the control system against the time delays. It turns out that the system output tracks the reference with a preassigned settling time ...
