1. Arthropod responses to the experimental isolation of Amazonian forest fragments
Arthropods are the most diverse and abundant group of animals found in tropical lowland forests, and in light of ongoing global change phenomena, it is essential to better understand their responses to anthropogenic disturbances. Here we present a review of arthropod responses to forest deforestation and fragmentation based on studies conducted at the Biolog

2. Avaliação do novo modelo global do CPTEC/INPE na previsão numérica de tempo de fenômenos tropicais / Evaluation of the new global model of CPTEC/INPE in the numeric weather prediction of tropical phenomena
It is important the study of meteorological phenomena that affect the tropical area as the squall lines, main responsible for the precipitation for this area and the "friagens" that cause decrease of the temperature. In this work the capacity of the model was evaluated in forecasting such phenomena, using different horizontal and vertical resolutions, using

3. Aceleração da consolidação em solos tropicais com drenos condutores elétricos / Acceleration of consolidation on tropical soil with electro conductor drain
The electrokinetic method has been studied by a growing number of research centers, in application such as mining engineering, civil and environmental engineering, food and sports. To meet the application needs it was necessary to develop a new technology that combines a variety of materials, functions and processes for the implementation of specific activit

4. Application of vinasse in soils: effect on soil charges and particle dispersion / AplicaÃÃo de vinhaÃa em solos: efeito no balanÃo de cargas e dispersÃo de partÃculas
The vinasse is the main byproduct of the ethanol and sugarcane brand production; these activities are in large expansion in Brazil. For a long time the vinasse was launched into water courses, generating negative environmental impacts. One of the alternatives for producers to get rid of vinasse is its addition in soils as fertilizer. Although the effects of

5. Trophic niche of Tropidurus hispidus (Sauria: Tropiduridae) in restinga environment / Nicho trofico de Tropidurus hispidus (Sauria: Tropiduridae) em ambiente de restinga
The diet is one of the main atributes of the ecological niche of animal species. Generally, the individuals of a population are considered ecologically equivalent in ecological studies that focus on resource use. Nevertheless, this approach has been inadequate to correctly describe resource use by various species, as demonstrated by empirical data. Intrapopu

6. Studies of the alterations of the integral juice of maracuja in packing of the type pet and glass. / Estudos das alteraÃÃes do suco de maracujà integral em embalagem do tipo pet e vidro.
In Brazil, is traditional the consumption of plain tropical fruit juices bottled in glass or PET materials. The packaging materials are essential to protect the food product and to preserve its inherent quality during the storage. However sorption phenomena from food to packaging materials and the migration phenomena from packaging to the food may alter the

7. Avaliação da técnica de termografia infravermelha para identificação de estruturas ocultas e diagnóstico de anomalias em edificações: ênfase em edificações do patrimônio histórico
The main objective of this work is to research and evaluate the results of the application of heat transfer techniques: radiation (infrared thermograph) and conduction (thermopar sensors) as a tool of diagnosis of the presence of hidden structures and anomalies at edifications which belong to the Brazilian Historical Patrimony. The utilization of a non-destr

8. Estudos da camada limite noturna na Amazônia / Studies about the nocturnal boundary layer in Amazonia: observational and modeling patterns
The goal of this work is studying the dynamics and structure of the Nocturnal Boundary Layer in Amazônia, over forest and deforested areas (pasture) and determining their characteristics during the dry and wet seasons on that region, as well as its mainly development controlling mechanisms. To this end, have been used 2 data sets for the dry and wet seasons

9. EFFECTS OF ATMOSPHERIC MULTIPATH IN LINE-OF -SIGHT MICROWAVE SYSTEMS / EFEITOS DE MULTIPERCURSOS ATMOSFÉRICOS EM ENLACES DE MICROONDAS EM VISIBILIDADE
The variations which happen in the troposphere layers throughout the time in relation to the median condition of the signal cause various phenomena that change the received signal level at digital radio relay systems randomly. The random changes are named fading. Fading is normally classified as fast or slow. The former is normally associated with the atmosp

10. Incorporação de diretrizes bioclimáticas e de acessibilidade no projeto urbano. Estudo de caso na cidade de Jaboticabal, SP.
Cities have become a challenge to urban planning professionals. This paper aims to present environmentally adequate techniques of urban intervention to implement cities in the urban design. The methodological development of the research was based on a classical literature review, as well as on the analysis of recent documents, as agenda 21, concerning the en

11. Evolução morfodinâmica da região de influência estuarina do Rio Curimataú/RN, com ênfase nas alternativas do ambiente deposicional de manguezal e a integração de geodados em Sig
The estuaries are important investigation zones of the actual morphodynamic and of depositional facies of recent geological history. They are constituted in important receptor means of the coastal area sediments, where the evolutionary processes occur quickly. They are also attractive means for the development of anthropic activities, which in a disordered w

12. Stochastic and mesoscopic models for tropical convection
A new way to parametrize certain aspects of tropical convection through stochastic and mesoscopic models is developed here. The technical idea is to adapt tools from statistical physics and materials science to model important unresolved features of tropical convection. This new strategy consists of modeling the unresolved effects of convective inhibition in
