Estratégias de relativização nas variedades lusófonas

This paper, which examines restrictive and non-restrictive constructions in the Lusophone varieties, assumes that Portuguese has a set of relativization strategies that are recognized by typological linguistics as constructions that define related groups of languages. Thus, it is possible that these different strategies, when employed by the same linguistic system, not really constitute variants of the same syntactic variable but the speaker’s actual choices facing the necessity to perform different social and discursive functions.

Construções relativas nas variedades do português: uma interpretação discursivo-funcional

This work examines relative constructions in Portuguese varieties based on the principle that Portuguese has a set of relativization strategies that are recognized in typological linguistics as constructions that define related groups of languages. It is postulated that these different strategies, when employed by the same linguistic system, do not really constitute variants of the same syntactic variable, but they are the speaker’s actual choices facing the necessity to perform different social and discursive functions.

Aplicações do fluxo de Ricci à teoria da relatividade geral: estudo dos buracos negros

The flow of Ricci is an analytical tool, and a similar equation for heat geometry, a diffusive process which acts on a variety of metrics Riemannian and thus can be used in mathematics to understand the topology of varieties and also in the study geometric theories. Thus, the Ricci curvature plays an important role in the General Theory of Relativity, characterized as a geometric theory, which is the dominant term in the Einstein field equations. The present work has as main objectives to develop and apply Ricci flow techniques to general relativity, in this case, a three-dimensional asymptotically flat Riemannian metric as a set of initial data for Einstein equations and establish relations and comparisons between them.

Captura gravitacional de pequenos corpos por arrasto em um gás modelado usando equações hidrodinâmicas

In this work we have developed an apparatus in order to study the capture of asteroids by planets surrounded by a gas envelope during y-by, to do this we have brought an innovation by using a hydrodynamical gas. We began such project by studying particles trajectories with a code based on the analytical gas. After being used to this model we have started a process to elaborate a code which uses the gas in a numerical way. The hydrodynamical gas is described by equations which are not solved analytically. Therefore, it was used an algorithm able to model the gas by keeping all information of the gas in cells. Thus we have made a code to read such cell`s information and then to solve all calculations. Once this process is done, the program inform us all date about the simulated trajectories

Atividade antioxidante e determinação de fenóis totais, carotenoides, betacarotenos, licopeno e zinco em variedades branca, amarela e rosada de Manihot Esculenta Crantz

There are cassava varieties that present compounds as carotenoids, beta-carotene, lycopene and minerals important for human and animal health. The present study evaluated the antioxidant activity of the white, yellow and pinkish varieties of Manihot esculenta, by mean of the DPPH test and by the ferrous ion-chelating activity. Furthermore, the total phenols, carotenoids, beta-carotene, lycopene and zinc contents were also determined. Utilizing the DPPH test it was possible to find that extracts of boiled samples presented higher antioxidant activity (89.53% - pinkish) in comparison to the fresh samples (1.97% - white). For the ferrous ion-chelating test, the highest activity was found for the boiled pinkish variety extract (63.43%) and the lowest was for fresh yellow extract (17.34%) the white sample did not present activity. The highest concentration of total phenols and zinc content was obtained for the boiled pinkish variety extract 136.12 mg EAG/g of extract and 0,811ppm, respectively, in the concentration of 1000 µg/mL. The pinkish variety presented also higher quantity of pigments, including carotenoid (29.40 µg/g), beta-carotene (9.14 µg/100g) and lycopene (68.92%). According to the results obtained in this study it was possible to conclude that the yellow and pinkish varieties of M. esculenta present quantity of phenolic compounds and minerals sufficient to attribute the antioxidant activity and may thus contribute to reduce oxidative damage and be used as nutraceuticals or directly ingested in the diet to maintain good health.

Soluções numéricas de Equações Diferenciais Fracionária e Ordinária para o cálculo da distribuição da concentração em um sistema de compartimento

The purpose of this work was the study of numerical methods for differential equations of fractional order and ordinary. These methods were applied to the problem of calculating the distribution of the concentration of a given substance over time in a given physical system. The two compartment model was used for representation of this system. Comparison between numerical solutions obtained were performed and, in particular, also compared with the analytical solution of this problem. Finally, estimates for the error between the solutions were calculated

Localizando o pretérito perfecto compuesto na linha do tempo: o estágio da gramaticalização do PPC nas variedades diatópicas argentinas

The aim of this study was to observe Argentine diatopic varieties and to identify in which stage of the evolution of the pretérito perfecto compuesto (PPC) the use of compound tense fits into these variations. Therefore, we assume as assumptions (I) some authors` description of the evolutionary stages of this verb tense in Spanish, (II) the description of the values assigned to the perfecto compuesto in the dialect regions of Argentina and (III) the contributions of studies on grammaticalization for the verb tenses analysis.
