1. Estimativa do coeficiente de transferência de massa de oxigênio com o uso da técnica das sondas solúveis flutuantes: um estudo de laboratório
RESUMO A sonda solúvel flutuante (SSF) é considerada uma técnica de baixo custo para a estimativa do coeficiente de transferência de massa de oxigênio na interface ar-água (KL). Essa técnica se baseia no fato que KL pode ser correlacionado com a velocidade de dissolução do sólido solúvel (VS), uma vez que ambos os parâmetros são influenciados pe

2. High pressure abrasive water jet for excavation purpose: a tridimensional approach for cutting strategy
Abstract High pressure abrasive water jets (HPAWJ) are an emergent excavation technology. Despite being used for several applications since the nineteenth century, it is only in recent decades that this excavation purpose has been considered. This is the result of evolution in high pressure pump technology and parameter investigation. Special highlight shoul

3. Study of water entry of circular cylinder by using analytical and numerical solutions
Water impact phenomenon in the case of a circular cylinder is an important issue in offshore industry where cross members may be in the splash zone of the incident wave. An analytical method as well as a numerical solution are employed to study the water entry problem of a circular section. The procedure for derivation of the analytical formulas is demonstra

4. Estudo do jateamento em solos argilosos e sua aplicação à engenharia de fundações offshore / Study of water jets in clay and its application to offshore foundation engineering design
Most of all petroleum produced in Brazil is encountered in marine deposits where the water depth may exceed 1000 meters. Recent discoveries of new offshore oil fields have motivated studies in this area designed to develop new techniques applied to oil exploration. For the extraction of oil deposits floating platforms are commonly used, supported by anchorag

5. Estudo dos mecanismos de fluidização de areias com jatos de água / Study of the fluidisation mechanism in sandy soils using water jets
A fluidização é definida como a suspensão de partículas de um solo granular devido à ação de um fluxo ascendente, que cria uma força de arrasto suficiente para suportar o peso próprio das partículas, produzindo uma zona fluidizada. Neste trabalho são discutidos os mecanismos e os conceitos envolvidos na fluidização de solos arenosos com a utili

6. Drop Size Measurements in a Laboratory Scale Venturi Scrubber
Venturi scrubbers are high efficiency gas cleaners in which suspended particles are removed from gas streams by droplets formed by liquid atomisation, usually in the venturi throat. The size of the droplets formed is of fundamental importance to the performance of the equipment, both in terms of pressure drop and collection efficiency. In this study, drop si

8. Organized Cell Swimming Motions in Bacillus subtilis Colonies: Patterns of Short-Lived Whirls and Jets
The swimming motions of cells within Bacillus subtilis colonies, as well as the associated fluid flows, were analyzed from video films produced during colony growth and expansion on wet agar surfaces. Individual cells in very wet dense populations moved at rates between 76 and 116 μm/s. Swimming cells were organized into patterns of whirls, each approximate

9. Chemical signals in the marine environment: dispersal, detection, and temporal signal analysis.
Chemical signals connect most of life's processes, including interorganismal relationships. Detection of chemical signals involves not only recognition of a spectrum of unique compounds or mixtures of compounds but also their spatial and temporal distribution. Both spectral and temporal signal processing determine what is a signal and what is background nois
