1. Sobre modelagem matemática e formalismos estatísticos de sistemas complexos
Resumo Os Sistemas Dinâmicos Complexos são sistemas com propriedades emergentes inesperadas resultantes de processos sinérgicos de seus componentes. Estes sistemas aparecem na física e na química e desempenham um papel fundamental em sistemas biológicos. Tais sistemas requerem um tratamento teórico em termos de “Modelagem Matemática”, com os form

2. The multitemporality of life: an analysis from Philosophy of Biology
ABSTRACT Although the issue of temporality has mainly been studied from Physics, this topic also exhibits diverse interesting aspects that could be addressed from a biological perspective. One possible way of approaching this subject is to examine the kinds of temporalities involved in biological processes. In that vein, the aim of this article is to analyze

3. Determinism, chaos, self-organization and entropy
RESUMO Este trabalho discute duas mudanças de paradigma ocorridas na ciência ao longo do século XX: fi m do determinismo mecanicista, e fi m da aparente incompatibilidade entre a biologia, onde a emergência de ordem é lei, e a física, postulando a progressiva desordenação dos sistemas naturais. Reconhecemos hoje que três mecanismos desempenham papel

4. Sobre la supuesta heteronomía explicativa de la biología funcional
ABSTRACTIn accordance with a widespread point of view, aligned with the nomological conception of causal explanation, Functional Biology is subjected to a regime of explanatory heteronomy under which, organic phenomena should be causally explained by using laws of Physics and Chemistry. Against this perspective, the experimental conception of causation allow

5. Quetelet, el hombre medio y el saber médico
Using two books by Adolphe Quetelet, I analyze his theory of the 'average man', which associates biological and social normality with the frequency with which certain characteristics appear in a population. The books are Sur l'homme et le développement de ses facultés and Du systeme social et des lois qui le régissent. Both reveal that Quetelet's ideas ar

6. Qualidade física da cama de semeadura do solo em sistemas de manejo / Physical quality of the soil seedbed under management systems
The seedbed is one of the most important soil physical conditions for plant growth. The evaluation of the soil physical quality in such soil environment is essential to understand the factors that affect crop development, as it is where seed germination and plant emergence and establishment take place. The objective of the experiment carried out in Brazil wa

7. Aplicabilidade e validação do Geant4 para fótons e elétrons em radioterapia / GEANT4 applicability and validation to Photons and Electrons in Radiotherapy
Due to the increasing use of ionizing radiation in medical applications, in recent decades, the simulation codes for radiation interacting with matter, based on Monte Carlo Method, have been constantly adapted to applications in medical physics. TheMonte Carlo method is a statisticalmethod of numerical simulation of problems using essentially a sequence of r

8. CNBi: the new Brazilian National Consortium for Bioinformatics.
PRESENTATION: The National Consortium for Bioinformatics (CNBi) is a multidisciplinary center dedicated to research, development, management and technical support on questions arising from bioinformatics. It was created by a joint effort between three laboratories from São Paulo state in Brazil: the Genomic and Expression Laboratory (UNICAMP), Applied Bioin

9. Reflexões sobre a visão biomédica e a visão holísitca no tratamento das lombalgias crônicas
The physiotherapy represents actually, in the medical field, therapeutic specialty which uses resources and approaches that include two sorts of medical rationalities: the biomedical and the holistic practice, in the context of health-disease-cure finds itself increasingly under discussion. Both classical physics (Cartesian Newton model) and quantum physics

10. Superdifusão de caminhadas markovianas e não-markovianas. / Superdifusion of marcovian na non-marcovian walk.
Random walks are tools used in statistical physics to quantitatively describe the evolution of dynamical systems. Such systems are ubiquitous in Nature and each system requires a unique approach. Models of the motion of biological organisms are constructed based on the randomness observed in search strategies. Markovian models attempt to faithfully reproduce

11. Mecânica estatística de sistemas complexos: crescimento de tumores com diferenciação e mobilidade celular / Statistical mechanics of complex systems: growth of tumors with differentiation and cell motility
O câncer (neoplasia) é uma das principais causas de mortalidade no mundo. Apesar dos grandes avanços no diagnóstico e nas formas de tratamento, ele ainda representa um enorme desafio para os pesquisadores de muitas áreas. Recentemente houve uma importante descoberta que poderá fornecer um paradigma completamente diferente no entendimento de como o cân

12. Os Nematoda da plataforma continental da região sudeste brasileira sob a influência da Água Central do Atlântico Sul: Cabo Frio (RJ) e Ubatuba (SP) / The Nematoda of the continental shelf of the Brazil\ s southern region under the influence of the South Atlantic Central Water intrusion: Cabo Frio (RJ) and Ubatuba (SP)
Meiofauna is an important component of the marine benthic ecosystem as its densities are usually high in continental shelf sediments and respond quickly to environmental changes. Nematoda is the dominant group among meiofauna organisms, is highly diverse and can be used, as well as meiofauna, as a tool for natural and anthropogenic impacts monitoring. This s
