Comportamento de acasalamento de Mahanarva spectabilis (Distant, 1909) (Hemiptera: cercopidae).
Efeito do aquecimento global sobre pragas das pastagens.
Estratégias de recuperação de pastagens contribuem para mitigação da emissão de gases de efeito estufa, aumento da biomassa e da capacidade de suporte das pastagens. O Brasil tem sua economia dependente de recursos naturais, o que evidencia a necessidade de se estudar a sua vulnerabilidade e risco às mudanças climáticas, com intuito de diminuir e remediar os impactos.bitstream/item/174533/1/Cap-16-Livro-Aquecimento-Global.pd

The τ-plot, a multicomponent 1-D pole figure plot, to quantify the heterogeneity of plastic deformation
An approach is presented that allows multi-scale characterisations of heterogeneous deformation in crystalline materials by employing a range of characterisation techniques including: electron backscatter diffraction, digital image correlation and neutron diffraction powder measurements. The approach will be used to obtain critical information about the variations in parameters that characterise the deformed state in different crystallographic orientation texture components of a sample in a statistically significant way. These parameters include lattice strains, texture evolution, peak broadening, dislocation density, planar faults, phase changes and surface strain. This approach allows verification of models of plastic deformation to provide a more detailed view of plastic deformation heterogeneity at multiple length scales than obtained by other characterisation approaches. The approach demonstrated here is applied to two stainless steel alloys; an alloy that exhibits phase transformation during deformation and an alloy that remains the same phase all through deformation process

Two loop electroweak corrections to and in the B-LSSM
The rare decays and are important to research new physics beyond standard model. In
this work, we investigate two loop electroweak corrections to and in the minimal
supersymmetric extension of the SM with local gauge symmetry (B-LSSM),
under a minimal flavor violating assumption for the soft breaking terms. In
this framework, new particles and new definition of squarks can affect the
theoretical predictions of these two processes, with respect to the MSSM.
Considering the constraints from updated experimental data, the numerical
results show that the B-LSSM can fit the experimental data for the branching
ratios of and . The
results of the rare decays also further constrain the parameter space of the
B-LSSM.Comment: 33 pages, 9 figures, Published in EPJ
