Genetic parameters of Eucalyptus pilularis resistance to rust in controlled and field conditions
(2020-01-01)
This study compared the susceptibility of E. pilularis progenies (from Brazilian populations) to myrtle rust under controlled and field conditions in Brazil. High levels of resistance were observed under both controlled ...
The Field Education: a study on the conditions of schools in Agrarian Reform settlements
(Univ Nove Julho, 2021-09-01)
Field Education arises in Brazil as a result of the struggle process of rural social movements, especially the Settled Rural Workers Movement (MST). Thus, this work aims to demonstrate that despite public policies for rural ...
Closed poly-trajectories and Poincaré index of non-smooth vector fields on the plane
(2013-04-01)
This paper is concerned with closed orbits of non-smooth vector fields on the plane. For a class of non-smooth vector fields we provide necessary and sufficient conditions for the existence of closed poly-trajectorie. By ...
Charge dynamics, Majorana condition and the topology of the interacting electromagnetic field
(Maik Nauka Publishing / Springer SBM, 2017-12)
In previous works [1, 2], the 2-dimensional charge transport with parallel (in plane) magnetic field was considered from the theoretical point of view showing explicitly that the specific form of the emergent equation ...
STABLE PIECEWISE POLYNOMIAL VECTOR FIELDS
(Texas State Univ, 2012-09-22)
Let N = {y > 0} and S = {y < 0} be the semi-planes of R-2 having as common boundary the line D = {y = 0}. Let X and Y be polynomial vector fields defined in N and S, respectively, leading to a discontinuous piecewise ...
An alternative formulation for guided electromagnetic fields in grounded chiral slabs - Summary
(1997-12-01)
An alternative formulation for guided electromagnetic fields in grounded chiral slabs is presented. This formulation is formally equivalent to the double Fourier transform method used by the authors to calculate the spectral ...
Self-energies for interacting fields with a compactified spatial dimension
(Sociedade Brasileira de Física, 2008-06-01)
We study the self-energy of a model with a tri-linear coupling among spinless fields on a manifold with one spatial dimension compactified. The model is considered to be composed by a quantized scalar field interacting ...
PRODUCTION FIELDS AND PHYSIOLOGICAL QUALITY OF PANICUM MAXIMUM JACQ. CV. MOMBASA SEEDS
(Univ Federal Uberlandia, 2020-11-01)
The physiological quality of seeds is influenced by the climatic factors of production fields. The identification of the best conditions of P. maximum cv. Mombasa production fields allows the improvement of the seed sector. ...
Evolving Neural Conditional Random Fields for drilling report classification
(2020-04-01)
Oil and gas prospecting is an important economic activity, besides being expensive and quite complex, thus requiring close monitoring to avoid work accidents and mainly environmental damages. An essential source of information ...
