1. As ideias envolvidas na gênese do teorema fundamental do cálculo, de Arquimedes a Newton e Leibniz
Esse trabalho busca contribuir com o estudo das principais ideias que envolvem o Teorema Fundamental do Cálculo (TFC), desde a Matemática na Grécia Antiga até as contribuições de Newton (1642 - 1727) e Leibniz (1646 - 1716), no século XVII. Dada a abrangência de tal tema, focamos nossa atenção na questão da Incomensurabilidade e em decorrência, n

2. O desenvolvimento das metÃforas do conceito de infinito na educaÃÃo matemÃtica
Este trabalho aborda o conceito de infinito a partir da perspectiva de seu desenvolvimento histÃrico, dos aspectos cognitivos relacionados à sua compreensÃo e de suas implicaÃÃes para a educaÃÃo matemÃtica. Encontra-se, pois, o conceito de infinito no seio do desenvolvimento das ciÃncias, e por ser um conceito com o qual nÃo se tem experiÃncia emp

3. Nature and distribution of chromosomal intertwinings in Saccharomyces cerevisiae.
To elucidate yeast chromosome structure and behavior, we examined the breakage of entangled chromosomes in DNA topoisomerase II mutants by hybridization to chromosomal DNA resolved by pulsed-field gel electrophoresis. Our study reveals that large and small chromosomes differ in the nature and distribution of their intertwinings. Probes to large chromosomes (

4. Evaluation of the counterion condensation theory of polyelectrolytes.
We compare free energies of counterion distributions in polyelectrolyte solutions predicted from the cylindrical Poisson-Boltzmann (PB) model and from the counterion condensation theories of Manning: CC1 (Manning, 1969a, b), which assumes an infinitely thin region of condensed counterions, and CC2 (Manning, 1977), which assumes a region of finite thickness.

5. Simulation of the gel-fluid transition in a membrane composed of lipids with two connected acyl chains: application of a dimer-move step.
Phospholipids have been treated as dimers on a hexagonal lattice, and a move has been introduced that allows the dimers to move and change their orientation on the lattice. Simulations have been performed in which phospholipid chains have been treated as being either independent or infinitely coupled thermodynamically with regard to their conformational stat

6. Evolutionarily Stable Mutation Rate in a Periodically Changing Environment
Evolution of mutation rate controlled by a neutral modifier is studied for a locus with two alleles under temporally fluctuating selection pressure. A general formula is derived to calculate the evolutionarily stable mutation rate μ(ess) in an infinitely large haploid population, and following results are obtained. (I) For any fluctuation, periodic or rando
