Mangueira Bay is located south of Patos Lagoon. It receives poorly treated official and clandestine household and industrial effluents from the city of Rio Grande. This study analyzes parameters that characterize the water ...

This research examines the characteristics of Lake Guaíba’s waves with regard to their main parameters; significant wave height (Hs), period (T), direction of wave propagation and its connections with the ressuspension ...

As informações sobre ventos e ondas próximos da costa são dados críticos para os pesquisadores e técnicos que trabalham em projetos ligados às áreas de engenharia, geologia e oceanografia costeira, navegação e recreação. ...

A model for the propagation of sea and swell waves in a channel bounded by rubble-mound jetties is presented. The model combines elements of earlier work on waves normally incident on a breakwater with a modified ...

Field measurements of surface gravity waves along the center line of the straight, 1 km long, 8 m deep, 250 m wide Mission Bay entrance channel (bounded by rubble-mound jetties) are compared to a model developed in a ...

In the present work, the steady approximation for accelerating and decelerating flows through tube banks is discussed. With this purpose, the experimental study of velocity and pressure fluctuations of transient turbulent ...

O trabalho aborda a Web Semântica: a nova versão da web que está em desenvolvimento, através de projetos como o Scorpion1 e o Desire2. Estes projetos buscam organizar o conhecimento armazenado em seus arquivos e páginas ...

Studies on well-being and its possible determinants are rare in the international literature, and almost non-existent in Brazil, particularly among youth. The present study focused on the epidemiology of well-being among ...

White spot syndrome virus (WSSV) is a doublestranded rod-shaped DNA virus, which belongs to the family Nimaviridae, genus Whispovirus (Mayo 2002). Since its first appearance in 1992 (Chou et al. 1995), the disease has ...

We test the hypothesis that predatory benthic fishes play a similar ecological role in different estuaries by displaying the same feeding strategy. We used whitemouth croaker (Micropogonias furnieri) populations in four ...

Strontium and barium incorporation into otoliths was compared between whitemouth croaker, Micropogonias furnieri, collected from an entrapped freshwater population (Mirim Lagoon) and a normal marine/estuarine population ...

Copepods have been widely used to evaluate toxicity of metals present in marine environments. However, a technical difficulty is to understand the possible routes of metal uptake and to identify in which tissues or organs ...

The two-dimensional barotropic, hydrodynamic and transport model MOHID is applied to the Patos Lagoon system using a nested modelling approach to reproduce both the lagoon and estuary hydrodynamics. A new Lagrangian oil ...

O presente artigo explora a célebre polêmica entre Windscheid e Muther, na segunda metade do século XIX, valendo-se de uma abordagem que procura inovar ao tratar do tema a partir dos referenciais teóricos da história das ...

O fracionamento de óleos via “winterização” consiste numa cristalização fracionada, na qual os triacilgliceróis de óleos e gorduras são separados pela cristalização parcial na fase líquida. O objetivo deste trabalho consistiu ...

Society is marked by relations of power that stratify itself. Relations that are marked by inequality in view of the uneven spaces occupied by men and women. If, on the one hand, man are responsible for public spaces ...

Objective. To describe the worldwide prevalence of physical inactivity and to analyze its association with development level of each country. Methods. Pooled analysis of three multicenter studies, conducted between 2002 ...

This study aimed to evaluate xanthan gum as a carrier of preservative solution and calcium chloride in edible coating applied to fresh-cut apple. The utilized coatings, prepared in aqueous solution, were: (T1) control, ...

A eclosão de uma crise econômica, política e social sem precedentes na Venezuela coloca o Brasil como protagonista enquanto nação receptora da diáspora venezuelana. Devido ao intenso fluxo migratório, o estado de Roraima ...

The main contribution of this paper is to introduce an autonomous definition of the connective “fuzzy exclusive or” (fuzzy Xor, for short), which is independent from others connectives. Also, two canonical definitions of ...
