13. INVESTIGAÇÃO DA SUPRESSÃO DE FLUORESCÊNCIA DE SORO ALBUMINA BOVINA E HUMANA POR COMPLEXO DE RUTÊNIO
The binding of [RuCl2(L)] (L = N,N-bis(7-methyl-2-pyridylmethylene)-1,3-diiminopropane) to bovine and human serum albumin was investigated by the fluorescence quenching technique. The comparison of the quenching effect of serum albumin fluorescence by ruthenium complex allowed the estimation of subdomain IB in BSA and subdomain IIA in HSA as the binding site

14. Process-based simple model for simulating sugarcane growth and production
Dynamic simulation models can increase research efficiency and improve risk management of agriculture. Crop models are still little used for sugarcane (Saccharum spp.) because the lack of understanding of their capabilities and limitations, lack of experience in calibrating them, difficulties in evaluating and using models, and a general lack of model credib

15. Body movement implied by static images modulates eye movements and subjective time estimation
The present study investigated the influence of body movement implied by artwork on time estimation and its relationship with eye movement. In Experiment 1, the participants were presented with static photographic images of Edgar Degas sculptures that implied different movements. The participants were asked to estimate their exposure times. Overestimation wa

16. Turix, a dynamic mechanistic model for feed evaluation
The objective of this study was to use the Turix model (a new mechanistic dynamic model that can be used for feed evaluation under tropical conditions), along with in situ and in vitro sugar cane experimental data from a previous study, to evaluate sugar cane kinetics through estimation of three parameters associated with ruminal bacterial growth: kM,SmL, th

17. Nova metodologia para análise de identificabilidade e estimação de parâmetros de modelos fenomenológicos
Model identification is the activity of constructing representative mathematical models of real systems. Several techniques are available for its completion, which depend on the level of information available about the studied system. In this work techniques for gray-box identification, which use both phenomenological models and experimental data, were studi

18. Modelagem e simulação de reatores autoclave para produção de PEBD
The low density polyethylene (LDPE) is a thermoplastic resin manufactured by high pressure processes, with autoclave or tubular type reactors. The present scenario is of growing demand for LDPE produced at competitive costs, through high performance and capacity plants, so that the process and product development becomes a key factor for the producers, and p

19. Estimativa da eficiência do ensaio SPT através da execução da prova de carga estática sobre o amostrador / Estimation of the efficiency in SPT test through static load tests to the sampler
The Standard Penetration Test, SPT, is one of the most used one for subsoil information in the USA and Brazil. The data obtained in this dynamic test, such as the penetration resistance index, NSPT, the soil classification and phreatic level are used by different methods to estimate the shallow and deep foundations load capacity. For the same soil, the index

20. Otimização em ambientes dinâmicos com variáveis contínuas empregando algoritmos de estimação de distribuição / Real-parameter optimization in dynamic environments using estimation of distribution algorithms
O dinamismo do mundo moderno traz consigo grandes desafios científicos e tecnológicos, particularmente junto a problemas de otimização. Problemas antes tratados de forma estática estão sendo reformulados para incorporar esse dinamismo, exigindo com isso novas estratégias de solução. Meta-heurísticas populacionais para otimização surgem então com

21. Estimação de sinais caóticos com aplicação em sistemas de comunicação
As comunicações têm alcançado grande desenvolvimento em várias frentes ao longo dos anos. Dentre estas, a comunicação utilizando sinais caóticos vêm sendo objeto de crescente interesse por parte dos pesquisadores devido às características de espalhamento espectral e difícil detecção. Entretanto estas técnicas ainda apresentam um desempenho inf

22. Probabilistic approach for yield analysis of dynamic logic circuits
In deep-submicrometer technologies, process variability challenges the design of high yield integrated circuits. While device critical dimensions and threshold voltage shrink, leakage currents drastically increase, threatening the feasibility of reliable dynamic logic gates. Electrical level statistical characterization of this kind of gates is essential for
