Foraminíferos são protistas sensíveis a mudanças ambientais e atuam como paleoindicadores de características oceanográficas como temperatura, salinidade, fluxo de oxigênio, disponibilidade de nutrientes e gradiente de energia do meio. A iden

A região antártica é foco de constante observação por ser uma região de importante monitoramento climático global. Ao sedimento de fundo marinho está associada uma biota que responde aos processos de alterações ambientais e dentre seus repr

Foraminifera are single-cell eukaryotes common in all marine environments and generally characterized by shells, more specifically termed “tests”, which can either be organic, agglutinated, calcareous, and rarely siliceous. The diversity of foram

Monitoring studies to characterize coastal environments and/or describe the direct impact of pollutants on foraminiferal fauna must be based on the living assemblages. The aim of this study is to review a benthic foraminifera dataset of a bio-monitor

One late Quaternary sediment core from the continental slope of the northern sector of Pelotas Basin (southern Brazilian continental margin, 2091 m water depth) was analyzed in order to evaluate the influence of the organic matter influx in the benth

In this work, we have studied the structural and magnetic properties of yttrium iron garnet nanoparticles doped with copper obtained by sol gel method. The lattice parameter decreases from 12.3779 A to 12.3774 A, for low doping and increases from 12.

We measured the stable isotopic composition of Globocassidulina biora from 17 surface sediments in Admiralty Bay, King George Island, taken during four consecutive austral summers (2002/2003–2006) spanning 44–80 m water depth. This species is wid

Objective: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in the elderly and a major cause of stroke. Compared to standard care procedures, prolonged Holter electrocardiogram (ECG) monitoring might increase detection of AF.

In this work, we have studied the role of Y ions on the structural, magnetic and optical properties of Fe-doped ZnO nanoparticles synthesized by the sol gel method. Rietveld refinement confirmed the single phase of ZnO, without any secondary phase. T
