1. Short-term stability of estuarine benthic assemblages: are storms pattern-defining events?
Storms, associated with strong winds and heavy rains, are often the most severe physical disturbances in shallow coastal areas causing instability to sedimentary environments. We hypothesized herein that if storms influence short-term assemblage structure of macrofauna, then assemblages should change after storms, while remaining relatively stable over calm

2. Ecomigrantes, refugiados ou deslocados ambientais: populações vulneráveis e mudança climática
Droughts, floods, severe storms, melting ice caps and consequent rise in sea level are some of the consequences of climate change. Concerning the human side of the climate change, some experts estimate that 200 million to 250 million people will be forced off their land by mid-century and the European Union itself has already established that migration press

3. CONDIÇÕES ATMOSFÉRICAS CONDUCENTES À OCORRÊNCIA DE TEMPESTADES CONVECTIVAS SEVERAS NA AMÉRICA DO SUL / ATMOSPHERIC CONDITIONS CONDUCIVE TO THE OCCURRENCE OF SEVERE CONVECTIVE STORMS IN SOUTH AMERICA
Neste trabalho é realizada uma investigação dos ambientes favoráveis ao desenvolvimento de convecção severa nos subtrópicos da América do Sul (AS) à leste dos Andes. Sondagens de ar superior das 00Z e 12Z de seis estações distribuídas na região subtropical da AS (quais sejam: Porto Alegre/BRA, Florianópolis/BRA, Curitiba/BRA, Foz do Iguaçu/BRA

4. Evolution of Dst and auroral indices during some severe geomagnetic storms
As evoluções dos índices Dst geomagnético e AU, AL e AE da aurora foram investigadas em relação aos parâmetros interplanetários de treze tempestades (com índices Dst maiores que 250 nT), no período entre 1980 e 2003. As mudanças no índice Dst ocorreram toda vez que a componente Bz do campo B magnético interplanetário se tornou negativa. Entre o

5. Investigation of the real time communication problem with consumers during energy supply interruption in critical days. / Estudo do problema da comunicação em tempo real com o consumidor na situação de interrupção de fornecimento de energia elétrica em dias críticos.
Severe weather conditions such as hurricanes, lightning storms, etc. have the potential to seriously damage electric utility transmission and distribution systems. This type of damage will disrupt electrical service until the physical facilities can be replaced or repaired. Then large storms can result in a massive number of customer outages, sometimes takin

6. Estudo da eficiência das parametrizações convectivas na simulação de eventos severos ocorridos no Brasil, utilizando o BRAMS
O objetivo geral dessa dissertação de mestrado foi estudar a influência das Parametrizações de Convecção na simulação de eventos severos no Brasil, a fim de avaliar o seu desempenho na previsão regional de tempestades potencialmente destruidoras. Com esse raciocínio, comparou-se a precipitação observada e simulada, estudaram-se as reservas de en

7. Implementação de uma rede neural artificial para associação de imagens de radar meteorológico e dados de descargas elétricas / A combination of weather radar images and electrical discharges using an artificial neural network
This work uses radar images together with data of electrical discharges derived from a lightning localization system taken with a Doppler Meteorological Radar as the input to a Neural Network (NN), in order to stablish the non-linear relationship between the reflectivity in the radar images and the atmospheric discharges. Associating these atmospheric discha

9. Ecologia populacional de Anaea ryphea(LEPIDOPTERA: NYMPHALIDAE) : fatores a tuando nas fases imaturas
Population studies developed in São Paulo and Panama showed striking differences in the main regulating factors of the continuously breeding tropical butterfly Anaea ryphea. The butterfly occurs from southern Brazil to Mexico, and uses different primary larval food plants in different regions: Croton floribundus at Campinas, São Paulo, Brazil and Croton bi

10. Gabapentin in the management of dysautonomia following severe traumatic brain injury: a case series
The pharmacological management of dysautonomia, otherwise known as autonomic storms, following acute neurological insults, is problematic and remains poorly researched. This paper presents six subjects with dysautonomia following extremely severe traumatic brain injury where gabapentin controlled paroxysmal autonomic changes and posturing in the early post�

11. Comparative impacts of two major hurricane seasons on the Neuse River and western Pamlico Sound ecosystems
Ecosystem-level impacts of two hurricane seasons were compared several years after the storms in the largest lagoonal estuary in the U.S., the Albemarle–Pamlico Estuarine System. A segmented linear regression flow model was developed to compare mass-water transport and nutrient loadings to a major artery, the Neuse River Estuary (NRE), and to estimate mean

12. Wave energy and intertidal productivity
In the northeastern Pacific, intertidal zones of the most wave-beaten shores receive more energy from breaking waves than from the sun. Despite severe mortality from winter storms, communities at some wave-beaten sites produce an extraordinary quantity of dry matter per unit area of shore per year. At wave-beaten sites of Tatoosh Island, WA, sea palms, Poste
