Suspension mechanics: I. Inertial and non-Newtonian migration of neutrally buoyant rigid spheres in two-dimensional unidirectional flows; II. The effect of viscoelasticity on the creeping motion of a train of neutrally buoyant Newtonian drops through a circular tube

The lateral migration of neutrally buoyant rigid spheres in two-dimensional unidirectional flows was studied theoretically. The cases of both inertia-induced migration in a Newtonian fluid and normal stress-induced migration in a second-order fluid were considered. Analytical results for the lateral velocities were obtained, and the equilibrium positions and trajectories of the spheres compared favorably with the experimental data available in the literature. The effective viscosity was obtained for a dilute suspension of spheres which were simultaneously undergoing inertia-induced migration and translational Brownian motion in a plane Poiseuille flow. The migration of spheres suspended in a second-order fluid inside a screw extruder was also considered.

The creeping motion of neutrally buoyant concentrically located Newtonian drops through a circular tube was studied experimentally for drops which have an undeformed radius comparable to that of the tube. Both a Newtonian and a viscoelastic suspending fluid were used in order to determine the influence of viscoelasticity. The extra pressure drop due to the presence of the suspended drops, the shape and velocity of the drops, and the streamlines of the flow were obtained for various viscosity ratios, total flow rates, and drop sizes. The results were compared with existing theoretical and experimental data.

The use of freshwater science in policy development

This article explores the diversity of scientific disciplines and paradigms, their relevance for policy development, how policy emerges throughout society,-and the mechanisms by which scientists can promote the value of science in policy formation. The author gives examples from various countries where freshwater science was used to inform policy.

Investigations on the vertical migration of planktonic Crustacea in the Bodensee-Obersee. [Translation from: Schriften des Vereins fur Geschichte des Bodensees und seiner Umgebung, 87, 177-187, 1969.]

The vertical zoning of the planktonic Crustacea in a lake is the expression of a complex set of different factors. Besides the measurable, external influences such as light, temperature, acid and C02 stratification, a particularly large part is played by internal factors, which co-ordinate a specific reaction in each species depending on state of development, age and sex. Supporting this extensive, predictable, annual course of diurnal depths and the daily vertical migrations, whose extent is again dependent on external conditions, primarily of course on the amount of light. The individual factors mentioned, however, are here also of great significance. Within the scope of a long-term study of the planktonic Copepoda of Lake Constance, some day and night series were in 1963 also carried out in the Obersee, in order to obtain at least volumetric data on the extent of the daily migrations of these creatures.

On drift and diel vertical migration of bottom invertebrates of the Amur. [Translation from: Zoologicheskie Zhurnal 42 1601-1612, 1963.]

Planktobenthos was sampled in 1957-58 in the river Amur. A determination of the kind of organisms drifting in the mass of water of the Amur was carried out. Of special interest for the authors was the activity of drifting of benthic larvae.

Bird migration and the spread of Crustacea. [Translation from: Verhandlungen der Deutschen Zoologischen Gesellschaft 27, 311-316, 1963.]

The passive spread of a high percentage of freshwater organisms is one of the most important requirements in short-lived and insular communities for species to attai n and survive - and consequently to balance the lack of a topographical continuity of most inland waters. Unfortunately hardly anything is known about the amounts of seed material typical for any lake into which it is carried. The causes of passive dissemination - wind, water and animals as well as man - are confirmed by many examples. It has been assumed now for at least a hundered years that , among animals, birds play a prominent role, although also disappointingly few facts are at hand. The passage and spread through birds' intestines has up to now been supported only by some limited data. This paper reports on experimental research where the eggs of Daphnia magna, Triops cancriformis, Artemia salina, Diaptomus spinosus and Cypris pubera were introduced by means of gelatine capsules into the oesophagus of a drake. The bird's excrements were inspected under a microscope for eggs and resting stages, and these were transferred into corresponding cultures.

O papel dos grupos de interesse no "trade policy making" brasileiro: o caso das negociações Brasil-Argentina para o setor automotivo

Desde a redemocratização do país em 1985 o MRE já vinha se posicionando à favor do diálogo com os mais diversos grupos e entidades sociais. Neste sentido, observou-se ao longo dos últimos anos um aprofundamento da interação com parlamentares, governos estaduais e municipais, empresários, sindicalistas, ONGs e imprensa. A construção de vínculos entre as organizações da sociedade civil críticas das negociações comerciais ao longo da década de 1990 permite falar na criação de um novo campo de ação coletiva transnacional, definido como um espaço de ação política formado por indivíduos e organizações da sociedade civil que participam do processo de elaboração de um conjunto comum de práticas, objetivos e crenças. O que se pode concluir é que diante de um contexto mais competitivo e globalizado, após processo de abertura comercial e intensificação da participação brasileira nas negociações internacionais, a representação dos interesses da classe empresarial teve que se adaptar criando uma nova forma de organização. Desse modo, o presente trabalho visa analisar a crescente interferência de grupos de interesse no processo de tomada de decisão, no que tange aos assuntos de política externa comercial brasileira, tais como as negociações comerciais internacionais por se tratar de um ambiente cujos interesses da classe empresarial mais podem ser afetados. As negociações comerciais internacionais é o ambiente em que a atuação empresarial mais pode ser percebida. As negociações do Mercosul e da ALCA possibilitam observar a participação ativa destes novos atores. Sendo assim, o trabalho apresenta a nova dinâmica de relacionamento entre Estado e grupos da sociedade civil (classe empresarial) para temas ligados a comércio exterior.
