1. Stochastic modeling of flexible rotors
Flexible rotors are characterized by inherent uncertainties affecting the parameters that influence the dynamic responses of the system. In this context, the handling of variability in rotor dynamics is a natural and necessary extension of the modeling capability of the existing techniques of deterministic analysis. Among the various methods used to model un

2. Caracterização da carga física de trabalho na horticultura orgânica / Characterization of the workload on the organic horticulture
There are many researches on organic agriculture regarding technical, economic or ecological issues; few researches, however, tries to identify the characteristics of the workload in organic agriculture under an ergonomic perspective. This project aimed the characterization of the physical workload in organic horticulture by determining the frequency of expo

3. Transposição e fragmentação do Rio Piumhi (Bacia do Rio São Francisco, MG): variáveis limnológicas e microcrustáceos zooplanctônicos da Lagoa dos Tropeiros
The aim of this study was to analyse the physical and chemical characteristics of Tropeiros Lake (Capitólio, MG), located in Piumhi river sub‐basin, a river diverted from the Rio Grande basin to the são Francisco River basin, and to analize the taxonomic composition, abundance, diversity and the size structure of the planktonic microcrustaceans. Phys

4. Rb-Sr systematics of holocene pelitic sediments and their bearing on whole-rock dating
In many cases, when dealing with argillaceous fine-grained sedimentary rocks, the isotopic ages obtained from Rb–Sr whole-rock isochron calculations are of geological significance, despite the fact that the initial conditions of Sr isotopic homogenization are not fulfilled. To explain this, a mechanical mixing during deposition has been suggested, leading

5. Measures of the interannual marine variability on southeast Brazilian bight and its relationship to the spawning areas of Brazilian sardine (Sardinella braziliensis) / Medidas da variabilidade interanual marinha sobre a plataforma continental sudeste do Brasil e sua relação com áreas de desova da sardinha-verdadeira (sardinella brasiliensis)
This work aims to investigate the relation of marine interannual variability in a region located in southern coast of Brazil, also known as the Southeast Brazilian Bight (SBB) and the spawning areas of the Brazilian sardine (Sardinella braziliensis) in SBB. SBB marine ecosystems are related to a strong influence of a coastal upwelling system. Variables used

6. Uncovering the secrets of unusual phase diagrams: applications of two-dimensional Wang-Landau sampling
We use a two-dimensional Wang-Landau sampling algorithm to calculate the density of states for two discrete spin models and then extract their phase diagrams. The first system is an asymmetric Ising model on a triangular lattice with two- and three-body interactions in an external field. An accurate density of states allows us to locate the critical endpoint

7. Wang-Landau sampling of an asymmetric ising model: a study of the critical endpoint behavior
We use the Wang-Landau algorithm to calculate a density of states for an asymmetric Ising model on a triangular lattice with two- and three-body interactions in an external field. An accurate density of states allows us to determine the phase diagram and to study the critical behavior of this model at and near the critical endpoint. We observe a divergence o

8. Nematofauna associada ao cultivo comercial de mamoeiro e considerações sobre amostragem em campos infestados com Meloidogyne sp. e Rotylenchulus sp.
Mais de 35 espécies de fitonematóides são relatadas na rizosfera de mamoeiro (Carica papaya), com destaque para os nematóides das galhas. Essas populações ocorrem em comunidades constituídas por diferentes espécies e densidades populacionais que variam com a cultivar, estresse sobre a hospedeira e propriedades física, química e biológica do solo.

9. Floristica, Fitossociologia e Heterogeneidade em um povoamento com predominÃncia de Anadenanthera peregrina (Benth.)Speg. / FLORÃSTICS, PHYTOSOCIOLOGY AND HETEROGENEITY IN A STAND WITH PREDOMINANCE OF Anadenanthera peregrina (Benth.) Speg
The present study was developed in an ancient abandoned area of planting of Anadenanthera peregrina, on the campus of the Federal University of Lavras, MG of about 7,56ha. It was aimed to report the floristic composition of this area as well as its phytosociological structure, paying attention to the ecologic aspects of the species, as the regeneration, disp
