1. Ray Tracing and Applications to an Evaporation Duct Model Based on Data from Oceanographic Buoy Sensors
Abstract The two-dimensional ray tracing method allows an easy and fast modeling of tropospheric propagation in the microwave frequency range. A version of this method that determines ray trajectories, amplitudes and delays of the electromagnetic field, as well as the propagation loss in a two-dimensional inhomogeneous environment will be described. The impl

2. Protección antiincrustante de estructuras sumergidas mediante recubrimientos formulados con 7-hidroxi-4-metilcumarina
ABSTRACT Biofouling settlement on submerged structures such as ships, buoys, farms, off-shore platforms and meteorological stations induces economic losses as a consequence of material deterioration and withdraw from service. Environmental regulations focus on the use of environmental friendly products to replace metallic biocides included in antifouling pai

3. Efecto inhibidor del dióxido de germanio sobre el biofouling del puerto de Mar del Plata
ABSTRACT Marine biofouling on any new material immersed in seawater can lead to extra costs due to increased maintenance, or/and even mechanical wear, and/or biodeterioration that require costly antifouling measures. Fouling organisms growing on immersed manmade surfaces affect hulls, piers, buoys, aquaculture and pipes mainly. Following adsorption of a cond

4. Contribuição do aninhamento do modelo Eta no modelo de circulação geral atmosférico e acoplado oceano-atmosfera do CPTEC na previsão do clima de verão sobre a América do Sul e Atlântico Tropical / Contribution of nesting regional eta model in atmospheric and coupled ocean-atmosphere general circulation model in seasonal forecast over South America and Tropical Atlantic
This work aims to verify the advantage of nesting Eta model in global coupled ocean-atmosphere model (CGCM) in climate forecast over South America and Tropical Atlantic. Three ensembles hindcasts of ten summer (December, January and February) between 1997 and 2006. The hindcasts consist of two global models from CPTEC, one atmospheric (AGCM;T062L28) and anot

7. MODELAGEM E SIMULAÇÃO DA DINÂMICA DE BÓIAS DE SUPERFÍCIE ANCORADAS / MODELING AND SIMULATION OF THE DYNAMIC OF SURFACE MOORED BUOYS
In this work a method for two-dimensional dynamic analysis of a cylindrical buoy under surfaced waves and moored to the seafloor by a flexible riser is presented. The finite element model used to describe the dynamics of the maritime line was developed by Lustosa (2002). This is a two node beam element based on the Euler-Bernoulli theory, with the element ki

8. THE PROFESSOR AND THE DIFFICULTIES IN LEARNING: concepts and practices / O PROFESSOR E AS DIFICULDADES DE APRENDIZAGEM: concepções e práticas
This dissertation argues the participation of the professor in the relation that the student diagnosised with learning difficulties establishes with the knowledge. It presents the historical about the difficulty of learning in the Brazilian pedagogical speech from the research of Tiballi (1998), Patto (1999), and Angellucci et alli (2004), and presents the c

9. Análise da dispersão de larvas de lagostas no Atlântico tropical a partir de correntes geotróficas superficiais derivadas por satélites / Use of geostrophic currents derived from radar altimeter to study lobster larvae dispersion in the tropical atlantic
Three species of spiny lobster are harvested along the Brazilian coast (Panulirus argus, P. laevicauda and P. echinatus). The annual revenue amounts 50 to 60 million US dollars. These species have a relatively long planktonic larval phase (about one year), that enables the mean ocean currents to transport the larvae over long distances away from the original

11. Psychological intervention in the psychic suffering of child and adolescent involved with processes in justice transaction / Intervenção psicológica no sofrimento psíquico de criança e adolescente envolvidos com processos em tramitação na justiça
The suffering is part of the life, and the man has as challenge of its existence to give a direction to it. In psychological and physical suffering, they appear some basic questions of the existence human being to be analyzed, such as, to reorient the person in suffering to discover new adequacy to reality, to find ethos and pathos. The objective of this wor

12. Estudo do comportamento estatico e dinamico de um Riser vertical co boia de subsuperficie
Na atualidade as descobertas de óleo a grandes profundidades no mar têm levado ao desenvolvimento de campos localizados numa profundidade aproximada de 3000m, sendo então o sistema de Riser Híbrido Auto-Sustentável uma alternativa atraente. O presente trabalho apresenta os modelos matemáticos que descrevem o comportamento estático e dinâmico de um ri
