1. Genetic progress, adaptability and stability of maize cultivars for value of cultivation and use trials
ABSTRACT. Maize breeding programs conduct multi-environment trials every year to assess the performance of new cultivars in pre-releasing tests. The data are combined across sites and seasons to perform a joint analysis in order to obtain information that will help breeders to select the best cultivars for different environments. Beyond this, it is essential

2. Repeatability of agronomic characters in Brachiaria brizantha cultivars
This experiment was carried out with the objectives of determining repeatability coefficients, the number of harvests necessary to increase accuracy and the genotypic stability of yield characteristics in Brachiaria brizantha cultivars in the northeast region of Brazil in the period from July 2009 to March 2011. The experimental design used was completely ra

3. Estabilidade e estabilização de uma classe de sistemas não-lineares sujeitos a saturação
This work addresses the problem of stability analysis and stabilization of nonlinear rational systems subject to saturation. The approach used in this study is based on the differential algebraic representation (DAR) of rational systems and on a modified version of the generalized sector condition to deal with saturation. First, methods to characterize the s

4. Phenotypic stability and genetic gains in six-year girth growth of hevea clones.
Rubber tree (Hevea brasiliensis (Willd.ex Adr. de Juss.) Muell. arg.) budgrafts of seven were evaluated on five constrasting sites in the plateau region of the Sao Paulo State, Brazil. The objective of this work was to study the phenotypic stability for girth growth. The experimental design was a randomized block design with three replications and seven trea

5. Caracterização, estimativas e bifurcações da região de estabilidade de sistemas dinâmicos não lineares / Characterization, estimates and bifurcations of stability region of nonlinear dynamical systems
Estimar a região de estabilidade de um ponto de equilíbrio assintoticamente estável é importante em aplicações tais como sistemas de potência, economia e ecologia. A compreensão da estrutura qualitativa da fronteira da região de estabilidade é fundamental para estimar com eficiência a região de estabilidade. Caracterizações topológicas e dinâ

6. DIVERSIDADE DE ODONATA (INSECTA)EM SISTEMAS LÓTICOS DA SERRA DA BODOQUENA,MATO GROSSO DO SUL, BRASIL / Odonata (Insecta) from Serra da Bodoquena, Mato Grosso do Sul State, Brazil
The biggest obstacles for the conservation of tropical biodiversity are the lack of information, arising mainly from the lack of inventories of fauna in many areas. Data on distribution and species richness generated in these inventories, can subsidize these conservation plans and management of ecosystem with environmental protection, allowing the establishm

7. Sincronização de uma classe de sistemas não-lineares acoplados com aplicações em sistemas elétricos de potência / Synchronization of a class of coupled non-linear systems with applications in electric power systems
Synchronization of a class of coupled non-linear systems is studied in this work. From the theoretical point of view, we present synchronization results that provide sufficient conditions on the vector field and estimates of the coupling parameters that guarantee synchronization. Differently from the existing approaches in the nonlinear systems literature, o

8. Validação do modelo WEPP na predição de erosão hídrica para condição edafoclimática da região de Viçosa-MG / WEPP model validation in the prediction of water erosion for edaphic climatic conditions in the region of Viçosa-MG
The sensitivity analysis of the WEPP model demonstrated that for the Brazilian edaphic climatic conditions the most critical parameters from the soil are: the erodibility interril (Ki), the erodibility in rill (Kr), the critical shear strength (τc) and the effective hydraulic conductivity (Ke). Through is of fundamental importance the evaluation of the

9. Mathematical / Statistical and Physical / Meteorological Models for Short-term Prediction of Wind Farms Output
(...)The rapid increase of the wind power penetration in the conventional grids all over the world has been requiring (from electricity companies and wind farm promoters) a special attention to the short-term prediction of wind farms output. Fomented by interest and necessity, companies and promoters are collaborating with universities and other research cen

10. Funções de Lyapunov lineares por partes para sistemas lineares discretos no tempo com saturação ou zona morta nos controles
This thesis is dedicated to stability analysis of linear discrete-time systems with saturation ar deadzone in feedback controls, with special attention to unstable open-Ioop systems. Linear systems with perfectly known parameters and systems with uncertain parameters constrained to a compact polytope are considered. For systems with saturations, the main obj

11. Evidence that the bypassing ribosome travels through the coding gap
In translational bypassing, a peptidyl-tRNA::ribosome complex skips over a number of nucleotides in a messenger sequence and resumes protein chain elongation after a “landing site” downstream of the bypassed region. The present experiments demonstrate that the complex “scans” processively through the bypassed region. This conclusion rests on three ob

12. Polymerase chain reaction-aided genomic sequencing of an X chromosome-linked CpG island: methylation patterns suggest clonal inheritance, CpG site autonomy, and an explanation of activity state stability.
The 5' region of the gene encoding human X chromosome-linked phosphoglycerate kinase 1 (PGK1) is a promoter-containing CpG island known to be methylated at 119 of 121 CpG dinucleotides in a 450-base-pair region on the inactive human X chromosome in the hamster-human cell line X8-6T2. Here we report the use of polymerase chain reaction-aided genomic sequencin
