Properties of four-component Dirac operators describing graphene quantum dots
(2020)
The electronic properties of graphene quantum dots (GQDs) can be described by the two-dimensional Dirac equation with boundary conditions consistent with the tight-binding model on a honeycomb lattice. It is convenient to ...
Selective Current Compensators Based on the Conservative Power Theory
(Ieee, 2009-01-01)
This paper presents possible selective current compensation strategies based on the Conservative Power Theory (CPT). This recently proposed theory, introduces the concept of complex power conservation under non-sinusoidal ...
Selecting and ranking areas for conservation of Aegla (Crustacea: Decapoda: Anomura) in southern South America integrating biogeography, phylogeny and assessments of extinction risk
(John Wiley & Sons Ltd, 2019-05)
The rapid degradation of freshwater habitats in southern South America may cause the extinction of the endemic species of Aegla, as well as other freshwater species and components of riverside environments related to them. ...
Conservation of ecosystem services in Argiudolls of Argentina
(MDPI, 2020-12-19)
Mollisols are a fundamental component of global agricultural production. In the Argentine Pampas region, 65% of the Mollisols belong to Argiudoll great group. These soils have an agricultural aptitude, with limitations ...
Natural grasslands in the Chaco. A neglected ecosystem under threat by agriculture expansion and forest-oriented conservation policies
(Elsevier, 2015-12)
In most tropical and subtropical biomes, conservation strategies are mainly focused on the preservation of forests. However, neotropical dry forest and savanna ecoregions include open habitats that may deserve conservation ...
A Control Algorithm Based on the Conservative Power Theory for Cooperative Sharing of Imbalances in Four-Wire Systems
(Institute of Electrical and Electronics Engineers Inc., 2019)
© 1986-2012 IEEE. A cooperative control scheme based on the conservative power theory (CPT) is proposed, which can share imbalances in three-phase four-wire droop-controlled systems. By utilizing the CPT, the balanced, ...
The soda lakes of Nhecolândia: A conservation opportunity for the Pantanal wetlands
(2019-01-01)
The Pantanal is the most conserved biome in Brazil and among the last wild refuges in South America, but intensification of agriculture and other land use changes present challenges for protecting this exceptionally ...
Load analyser using conservative power theory
(2013)
This paper deals with the analysis and application of novel conformity factors, defined by means of the Conservative Power Theory (CPT), for the purpose of load analysis and characterization. Basically, such factors are ...
Soil—Plant Relationships in Soybean Cultivated under Conventional Tillage and Long-Term No-Tillage
(2022-03-01)
Soybeans [Glycine max (L.) Merrill] have great economic prominence in the world, and soil management systems can directly interfere with their yield through changes in soil physical-hydric properties. Thus, the aim of this ...
Object oriented modeling of piston engines
(2001-12-01)
This work reports a conception phase of a piston engine global model. The model objective is forecast the motor performance (power, torque and specific consumption as a function of rotation and environmental conditions). ...
