1. Dietary intake of non-dialysis chronic kidney disease patients: the PROGREDIR study. A cross-sectional study
ABSTRACT BACKGROUND: Despite evidence that diet is very important in relation to chronic kidney disease (CKD) progression, studies in this field are scarce and have focused only on some specific nutrients. We evaluated the energy, macronutrient and micronutrient intakes and dietary patterns of non-dialysis CKD participants in the PROGREDIR study. DESIGN A

2. Online hybrid modeling method with application for predicting Bauxite production indicators
Abstract In the bauxite flotation process, concentrate grade and tailings grade are key production indicators; however, they are difficult to measure online. It is also difficult to develop an effective mathematical model for the process because of the complex non-linear and uncertain relationship among the feed parameters (feed grade, pulp density, slurry p

3. Computação evolutiva na resolução de equações diferenciais ordinárias não lineares no espaço de Hilbert. / Evolutive computation in the resolution of non-linear ordiinary diferential equations in the Hilbert space.
This thesis shows a new method to get polynomial solutions to the initial value problems (IVP), with an error margin comparable to the consecrate numerical methods (NM), for both the function and its derivatives. The method works with differential equations (DEs) linear or not, beeing the developed tolls available until 4th order, whose can be expanded to hi

4. Avaliação em ciencia, tecnologia e inovação : o caso do programa de propriedade intelectual da FAPESP / Evaluation of Science, technology and innovation : the case of FAPESP intellectual property program
The evaluation of research activities is essential for the goverrunental agencies involved in funding large programs of science, technology and innovation (S,T&I). Currently, evaluation initiatives have been used for legitimating of public spending resources and also to verify the resul.ts and impacts of the funded projects. Evaluation of such programs produ

5. Análise da base de pilares pré-moldados na ligação com cálice de fundação / Analysis of the precast concrete column base in the connection socket
The study presents the analysis of precast concrete column base in the connection socket. This research follows previous studies on this connection type. The research aim to fill out the lack of information about column base in the embedded length, because almost do not exist recommendations about this subject. An experimental investigation was developed wit

6. STABILITY ANALYSIS OF SLENDER COLUMNS PARTIALLY BURIED IN A NON-LINEAR ELASTIC FOUNDATION / ANÁLISE DA ESTABILIDADE DE COLUNAS ESBELTAS PARCIALMENTE ENTERRADAS EM UMA FUNDAÇÃO ELÁSTICA NÃO-LINEAR
O presente trabalho tem por objetivo estudar o comportamento de colunas esbeltas parcialmente enterradas, quando submetidas a um carregamento axial de compressão. A fundação é representada, ora por um modelo linear, o qual considera que a reação exercida pelo solo é proporcional às deflexões da coluna, ora por um modelo não-linear no qual esta rela

7. Estratégia de escalonamento de controladores PID baseado em regras Fuzzy para redes industriais foundation fieldbus usando blocos padrões
The main objective of work is to show procedures to implement intelligent control strategies. This strategies are based on fuzzy scheduling of PID controllers, by using only standard function blocks of this technology. Then, the standardization of Foundation Fieldbus is kept. It was developed an environment to do the necessary tests, it validates the propose

8. Estudo teórico-experimental da ligação pilar-fundação por meio de cálice em estruturas de concreto pré-moldado / Theoretical-experimental analysis of column-foundation connection through socket of precast concrete structures
This research presents a theoretical-experimental analysis of column-foundation connection through socket of precast concrete structures, with emphasis in pedestal walls. The experimental program included five models submitted to normal load with large eccentricity, changing the type and the condition of interface: three models had smooth interface and two m

9. On non-ideal and non-linear portal frame dynamics analysis using bogoliubov averaging method
We apply the Bogoliubov Averaging Method to the study of the vibrations of an elastic foundation, forced by a Non-ideal energy source. The considered model consists of a portal plane frame with quadratic nonlinearities, with internal resonance 1:2, supporting a direct current motor with limited power. The non-ideal excitation is in primary resonance in the o

10. Soluções transientes de problemas visco-elastodinamicos em meios ilimitados atraves da transformada de Fourier rapida - FFT
This dissertation describes a methodology based on the Fast Fourier Transfonn - FFT to synthesize transient Green and Influence functions for unbounded viscoelastic domains. The FFT algorithm is applied to Green or Influence functions that has been previously obtained in the frequency domain. The techniques used to treat the functions in the frequency domain

En este trabajo se desarrolla una metodología basada en el Método de los Elementos Finitos para estudiar el equilibrio y la estabilidad de placas apoyadas en fundaciones elásticas. La formulación utilizada para el análisis de placas es válida para el análisis lineal y no lineal de placas isotrópicas o ortotrópicas, perhechas o inicialmente imperhech
