Media coverage of Wildlife affected by Wildfires in brazilian protected areas

Biodiversidade Brasileira, 2019
Brazil is host of almost 120,000 animal species and therefore classified as "megadiverse". Although fire is a natural agent in some Brazilian ecosystems and fauna historically evolved with its presence, nowadays it can be a potential hazard to fauna ...

Extended quantum U(1)-liquid phase in a three-dimensional quantum dimer model

, 2011
Recently, quantum dimer models, in which the system can tunnel between different classical dimer configurations, have attracted a great deal of interest as a paradigm for the study of exotic quantum phases.

Modeling and Control of Grid-Forming Active Power Filters for Harmonic Suppression and Enhanced Power Quality

Applied Sciences
Grid-forming converters (GFMCs) have gained significant attention for their functionality in grid voltage formation and grid-supportive services. However, managing harmonic distortions caused by nonlinear loads remains a critical challenge in weak grids.

Ab initio calculations of nuclear widths via an integral relation

, 2012
I describe the computation of energy widths of nuclear states using an integral over the interaction region of ab initio variational Monte Carlo wave functions, and I present calculated widths for many states. I begin by presenting relations that connect

Light condition during grain-filling stage of main crop strongly influences ratooning ability of low-stubble ratoon rice

Crop and Environment
Compared with high-stubble ratoon rice (RR), low-stubble RR is superior in yield potential, grain quality, and economic benefit. However, the unstable ratooning ability limits the grain yield of low-stubble RR production. Light condition during the grain-

Large-basis shell-model calculations for p-shell nuclei [PDF]

, 1998
Results of large-basis shell-model calculations for nuclei with A=7-11 are presented. The effective interactions used in the study were derived microscopically from the Reid93 potential and take into account the Coulomb potential as well as the charge ...

Institutionalizing Advisory Bodies in Climate Governance: Between Transparency, Accountability and Efficiency

Environmental Policy and Governance, EarlyView.
ABSTRACT The implementation of effective climate governance increasingly relies on advisory bodies that monitor the effectiveness of policies and management mechanisms. Despite their strategic importance to institutionalizing climate governance, limited attention has been paid to the roles, trajectories, and effectiveness of these advisory bodies ...

Interaction mechanism of multi-time scale control loops between PLL-synchronized and power-synchronized converters

International Journal of Electrical Power & Energy Systems
The interaction of multi-time scale control loops between grid-following converters (GFLCs) based on phase-locked loop (PLL) synchronization and grid-forming converters (GFMCs) based on power synchronization introduces new instability risks. Based on the

The WMO vegetation fire and smoke pollution warning advisory and assessment system (VFSP-WAS)

Biodiversidade Brasileira, 2021
Vegetation fires - including the application of fire in land use, land-use change and uncontrolled wildfire - affect the functioning of the Earth System and impose significant threats to health and security.
