1. Interpolation method for live weight estimation based on age in Japanese quails
ABSTRACT The objective of this study was to demonstrate live weight estimation based on age by using Newton Interpolation method for male and female quails for seven weeks of fattening. A total of 138-day-old quail chicks were used in the study. The study demonstrated a 6th-degree polynomial interpolation for the function values obtained at seven equal inter

2. A Common-Feature Approach for Testing Present-Value Restrictions with Financial Data
It is well known that cointegration between the level of two variables (labeled Yt and yt in this paper) is a necessary condition to assess the empirical validity of a present-value model (PV and PVM, respectively, hereafter) linking them. The work on cointegration has been so prevalent that it is often overlooked that another necessary condition for the PVM

3. Analytical, empirical and phenomenological aspects of elastic hadron scattering at high energies / Aspectos analiticos, empiricos e fenomenologicos do espalhamento elastico de hadrons em altas energias
We investigate high-energy elastic hadron scattering by means of three different approaches: analytical, empirical, and phenomenological. The first one is characterized by the fundamental principles of analyticity and crossing symmetry, polynomial limits for the scattering amplitude and dispersion relations. In special, for classes of functions of physical i

4. Codimensões, cocaracteres, identidades e polinômios centrais Z$_2$-graduados da álgebra de Grassmann
Let E be the in_nite-dimensional Grassmann algebra over a _eld F of characteristic zero and consider L the F-vector space spanned by all generators of E. Let l be an automorphism of E of order 2 such that L is an homogeneous subspace. In this work, we study the Z2-gradings (E; l) induced by the automorphisms l and we _nd their Z2-graded codimensions and coch

5. Sobre derivações localmente nilpotentes dos aneis K[x,y,z] e K[x,y] / Over locally nilpotent derivations of the rings K[x,y,z] e K[x,y]
In this dissertation we present centraIs results on locally nilpotents derivations in a ring of polynomials B = k[x1, ..., xn], for n ≤ 3, which were presented by Daniel Daigle in [2], [3] and [4]. For this, we introduce basic fundamenta1 results of the theory of derivations in a ring and we present results on locally nilpotents derivations in a domain

6. Zeros of polynomials and properties polynomials in Banach spaces / Zeros de polinômios e propriedades polinomiais em espaços de Banach
Neste trabalho temos por objetivo apresentar alguns resultados relacionados aos temas abordados por Aron, Choi e Llavona (1995), Aron e Dimant (2002) e Aron e Rueda (1997). Primeiramente, vamos estudar as propriedades polinomiais (P) e (RP) para os espaços de Banach e a propriedade ACL para as funções definidas entre as bolas unitárias fechadas do espaç

7. Identidades polinomiais para a algebra das matrizes de ordem dois sobre corpos de caracteristica zero / Polynomial identities of the matrix algebra of order two over a field of characteristic zero
Esta dissertação introduz as primeiras noções para o estudo da teoria de álgebras que satisfazem identidades polinomiais (chamadas PI - álgebras), bem como alguns resultados importantes. Expomos alguns fatos e resultados fundamentais sobre representações dos grupos simétricos e geral linear. Estes resultados serão posteriormente utilizados para est

8. Teoria dos mÃdulos idealizadores diferenciais
Given an ideal in a polynomial ring (with coefficients in a field usually assumed to have characteristic zero), we may consider the derivations that preserve it. They give rise to a special module called differential idealizer (of the given ideal). Such an object plays a primordial role in this thesis, which is divided into two main sections. In the first se

10. Identidades polinomiais em algebras T-primas / Polynomial identities in T-prime algebras
In this work we study tensor products of T-prime T-ideals over infinite fields. The behaviour of these tensor products over a field of characteristic zero was described by Kemer. First we show, using methods due to Regev, that such a description holds if one restricts oneself to multilinear polynomials only. Second, applying graded polynomial identities, we

12. O metodo de Galerkin descontinuo com difusividade implicita e h-adaptabilidade baseada em tecnicas Wavelet
In this work an inovative technique is presented for the numerical approximation of conservation laws on unstructured meshes. The numerical scheme uses a discontinuous piecewise polynomial approximation with hadaptivity. The self-adaptive h-refinement strategy uses a regularity assessment of the solution based on wavelet techniques. This strategy determines
