1. Variações de produtividade da porção oeste do Atlântico Sul ao longo dos últimos 15 mil anos a partir de estudo quantitativo de nanofósseis calcários / Productivity changes of the western South Atlantic region during the las 15,000 years based on quantitative study of calcareous nannofossil
O objetivo do presente estudo foi estimar as possíveis variações na produtividade das águas superficiais da porção oeste do oceano Atlântico Sul ao longo dos últimos 15.000 anos, contribuindo para a melhor compreensão das variações oceanográficas ocorridas na região no decorrer deste tempo. Foram realizadas análises quantitativas de nanofóssei

2. Controle automatico eletronico de ganho com supressão de transientes aplicado a EDFAs em redes opticas WDM / Eletronic automatic gain control with transient suppresion applied over WDM optical networks
IIn WDM optical communication systems erbium doped fiber amplifiers (EDFA) have an essential function, enabling amplification of simultaneous channels independently of transmit rate. The majority of current WDM systems use point to point configuration operating with a fixed number of channels over the optical link. However, the new generation optical systems

3. Hydrodynamic effects on microcapillary motility and chemotaxis assays of Methylosinus trichosporium OB3b.
A study of the random motility and chemotaxis of Methylosinus trichosporium OB3b was conducted by using Palleroni-chamber microcapillary assay procedures. Under the growth conditions employed, this methanotroph was observed qualitatively with a microscope to be either slightly motile or essentially nonmotile. However, the cells did not not respond in the mic

4. Testing migration patterns and estimating founding population size in Polynesia by using human mtDNA sequences
The hypervariable 1 region of human mtDNA shows markedly reduced variability in Polynesians, and this variability decreases from western to eastern Polynesia. Fifty-four sequences from New Zealand Maori show that the mitochondrial variability with just four haplotypes is the lowest of any sizeable human group studied and that the frequency of haplotypes is m
