1. Efeitos da formação e operação de um reservatório de pequena regularização na alteração da qualidade da água e do regime hidrológico na planície de inundação do Pantanal
The formation of reservoirs changes the quality and quantity of water, both upstream and downstream, and the direction and magnitude of such changes depend on their characteristics of construction, operation, morphometry, as well as hydrological regime and climate of the region. However, much of this knowledge was based on large reservoirs, which is not the

2. Influência das frentes frias nos mecanismos de funcionamento da represa da UHE Carlos Botelho (Lobo/Broa) Itirapina SP, dos pontos de vista químico, físico e biológico
In Brazil there is a numerical predominance of river systems, which favors the construction of reservoirs. These reservoirs have great ecological, economic and social significance, so, the management, conservation and recovery of these systems are of fundamental importance with repercussions on the economy, social work and the uses of aquatic systems. Climat

3. The influence of stable stratification on the transition to turbulence in a temporal mixing layer
The transition to turbulence in a stably stratified flow is a problem of considerable interest in fluid dynamics with applications in both geophysical sciences and engineering. This transition is controlled by competition between the vertical shear of the base flow and the buoyancy forces due to the density stratification. The present work investigates numer

4. "Experimentos e modelagem numérica com aplicação ao Estuário Tropical do Rio Curimataú, RN" / Experiments and numerical model with application to the tropical estuary of the Catimataú river, RN
The distribution and variability of the termohaline properties and the three-dimensional circulation of the Curimataú river estuary had been studied with the application of the numerical model of simulations Delft3D-Flow, validated with experimental data measured during two consecutive cycles of neap and spring tide. Two numerical grids were applied with th

5. Climate, carbon cycling, and deep-ocean ecosystems
Climate variation affects surface ocean processes and the production of organic carbon, which ultimately comprises the primary food supply to the deep-sea ecosystems that occupy ≈60% of the Earth's surface. Warming trends in atmospheric and upper ocean temperatures, attributed to anthropogenic influence, have occurred over the past four decades. Changes in

6. Distribution and Diversity of Archaea Corresponding to the Limnological Cycle of a Hypersaline Stratified Lake (Solar Lake, Sinai, Egypt)
The vertical and seasonal distribution and diversity of archaeal sequences was investigated in a hypersaline, stratified, monomictic lake, Solar Lake, Sinai, Egypt, during the limnological development of stratification and mixing. Archaeal sequences were studied via phylogenetic analysis of 16S rDNA sequences as well as denaturing gradient gel electrophoresi

7. Thermophilic, anaerobic bacteria isolated from a deep borehole in granite in Sweden.
A borehole drilled to a total depth of 6779 m in granitic rock in Gravberg, Sweden, was sampled and examined for the presence of anaerobic, thermophilic, fermenting bacteria and sulfate-reducing bacteria. Growth in enrichment cultures was obtained only from water samples collected from a specific sampling depth in the borehole (3500 m). The hole was cased do
