1. TiF4 and NaF varnishes as anti-erosive agents on enamel and dentin erosion progression in vitro
Objective This study assessed the effect of fluoride varnishes on the progression of tooth erosion in vitro. Material and Methods: Forty-eight enamel and 60 root dentin samples were previously demineralized (0.1% citric acid, pH 2.5, 30 min), leading to a baseline and erosive wear of 12.9 and 11.4 µm, respectively. The samples were randomly treated (6 h) w

2. MensuraÃÃo da erosÃo do solo no semiÃrido em diferentes usos de terras e escalas espaciais / Measurement of soil erosion in semi-arid region at different uses and spatial scales
A obtenÃÃo de dados de erosÃo do solo em diferentes escalas espaciais à de fundamental importÃncia, principalmente no semiÃrido do Nordeste brasileiro onde esses dados sÃo escassos. O semiÃrido brasileiro à vulnerÃvel à erosÃo hÃdrica, principalmente devido Ãs suas caracterÃsticas climÃticas, edÃficas e Ãs prÃticas de exploraÃÃes insuste

3. Rates and processes of bank erosion, Itaipu Reservoir, Paraguay-Brazil border, South America
Measurement of erosion have been made on nine erosion stations along the south end of Itaipu reservoir, Paraguay-Brazil border, South America, between July 1993 and March 1995. Land-use, shoreline location (embayment or main truck of lake), fetch magnitude and associated wave energy are the critical factors influencing bank erosion. The cycle of erosion of b

5. Monitoramento por dgps e análise dos processos erosivos da linha de costa na praia de Pirangi do Norte - Parnamirim / RN
Through out the course of a steady increase in search and recovery of space in the coastal zone, there is also an expanding concern about the erosion processes of this area. The main problem in coastal areas is that urbanization occurs in a disorderly fashion and unsustainable, further aggravating the problems of coastal dynamics. The study area of this work

6. Validation of the NUTMON model for the diagnosis of agricultural management: study on two family farms in Rio de Janeiro State. / Validação do modelo NUTMON para o diagnóstico do manejo agrícola: Estudo em duas propriedades familiares do Rio de Janeiro.
This study had the following hypothesis: the agricultural production systems adopted by small farmers brings about nutrient negative balances to soil, which causes the loss of soil fertility and crop yield decline in the time span. The general objective of this study was to validate the NUTMON model of the Food and Agriculture Organization of the United Nati

10. Hydric erosion and initial development of the Eucalyptus grandis in a Red-Yellow Argisol submitted to different methods of soil preparation in the Vale do Paraíba-SP region / Erosão hídrica e desenvolvimento inicial do Eucalyptus grandis em um Argissolo Vermelho-Amarelo submetido a diferentes métodos de preparo de solo no Vale do Paraíba - SP
In Brazil, and especially in the state of São Paulo in the Vale do Paraíba region, eucalypt plantation is expanding to high declivity areas occupied with degraded pastures due to the limited agricultural value of these topographies and its greatest forest aptitude. Such areas are naturally more susceptible to the hydric erosion, which reduces the fores

11. Zoneamento geoambiental com auxílio de lógica fuzzy e proposta de um geoindicador para caracterização do meio físico da Bacia do Rio do Peixe / Geoenvironmental zoning using fuzzy logic and proposal of a geoindicador to characterize Rio do Peixe basin environment
This study presents a methodological technique to characterize environmental restrictions and aptitudes considering continuous variation in the attributes and gradation in contato between units. Fuzzy logic procedures were used to generate representation of contact gradation for rocky substratum and unconsolidated materials maps. Continuous attribute variati

12. High resolution positioning â suitability and aplication to coastal morphology / Posicionamento de alta resoluÃÃo â adequaÃÃo e aplicaÃÃo à morfologia costeira
The coastal zone concentrates a large economic potential and due to its importance to the sustainable development it was subject of discussion during the United Nations Conference on the Environment, Rio 92. The Agenda 21, the basic document generated during this conference, includes a specific chapter (Chap. 17) that deals with the protection of the oceans
