1. Morphometry and longitudinal profile of the river cobras sub-basin in planning the location of underground dams
RESUMO Um estudo na sub-bacia hidrográfica do rio das Cobras foi realizado com o objetivo de avaliar as características morfométricas e o perfil longitudinal da bacia hidrográfica, como ferramenta de planejamento na locação de barragens subterrâneas. Os parâmetros morfométricos - coeficiente de compacidade, fator forma, densidade de drenagem e índi

2. Sediment Morphology, Distribution, and Recent Transport Dynamics in a Reforested Fragment
Abstract Erosion generates large amounts of sediment, which may be deposited at the site of origin, on the slope of a hill, or along waterways. The transportability of each type of sediment by runoff and its potential for subsequent deposition largely depends on its morphological features and particle size distribution. The aim of this study is to describe a

3. Principal environmental impacts on pipeline tracks as a result of mining operations and their mitigated actions
Abstract This study deals with the main environmental impacts and possible mitigation measures for many pipeline tracks, due to the mining of different substances in areas of interference between mining activities and mineral research and those resulting from construction and gas pipeline operation. By monitoring the identified interferences/disturbances, it

4. Software para definiÃÃo e avaliaÃÃo de unidades de manejo em Agricultura de precisÃo / Software for definition and evaluation of management zones in Precision agriculture
Water and soil conservation is essential for water resources management. Thus, conservationist actions are developed and applied in order to make part of a set of measures which enable the supply management, based on an appropriate recharge of the aquifers as well as the improvement of their quality, from the reduction of erosive processes and volume of effl

5. Oral conditions and Streptococcus mutans isolation in patients undergoing bariatric surgery / CondiÃÃes bucais e isolamento de Streptococcus mutans em pacientes submetidos à cirurgia bariÃtrica
Introduction: Obesity is associated with oral diseases by promoting inflammatory processes and because of the fact that obese patients often eat cariogenic foods and use drugs capable of inducing salivary alterations. Bariatric surgery, surgical means of treating morbid obesity and obesity associated to co-morbidities, aims to change the volumetric capacity

6. Implications of landforms in connection with soil versus evolution and installation of the tunnels / ImplicaÃÃes da relaÃÃo solo versus relevo na instalaÃÃo e evoluÃÃo de tÃneis
Whereas erosion is a process that detracts from the soil, reducing its productivity or even making impossible the food production in it, it is worth emphasizing the importance of studies on this topic, especially with explanations and solutions to problems found in areas that are degraded by erosive processes. The installation and evolution of this process d

7. CaracterizaÃÃo da cobertura superficial em encosta na Bacia do Rio das Pombas, Guarapuava â PR: bases para entendimento da gÃnese erosiva em tÃneis / Characterization of hillside superficial covering at the basin of Rio das Pombas, Guarapuava, Paranà state: basis for understading of tunnel erosion genesis
On the Guarapuava Plateau/Palmas, in a low slope hillside of superficial covering from basaltic origins, on the right bank of the Rio das Pombas, Paranà state, processes of tunnel erosion (pipes) were identified. These are subsuperficial erosion processes with typical features, such as subsidence of the tunnel roof and rebate structures, which tend to evolv

8. Evaluation of the lisem model for the simulation of hydrosedimentologic processes in a small rural catchment on the basalt slopes of Rio Grande do Sul, Brazil / Avaliação do modelo LISEM na simulação dos processos hidrossedimentológicos de uma pequena bacia rural localizada nas encostas basálticas do Rio Grande do Sul
The intensive cultivation of the areas of southern Brazil that have poor agricultural potential (shallow soils on steep, basaltic hillsides) has contributed to the degradation of the environment by increasing rates of soil erosion and sediment yields. In this study, traditional monitoring methods have been combined with concurrent mathematical modeling to ve

9. INDICADORES BIOLÓGICOS, FÍSICOS E SOCIAIS DE IMPACTO AMBIENTAL: CARACTERIZAÇÃO E APLICAÇÃO PARA AS TRILHAS DO PARQUE ESTADUAL DO IBITIPOCA, MG - BRASIL
The aim of this study was to evaluate the conservation status of the trails and their marginal areas of the Ibitipocas State Park by monitoring of environmental impact indicators selected and implemented in seven trails of the park. The methodology used is the method VIM (Visitor Impact Management). For monitoring 23 indicators parameters were selected, bein

10. Morfologia e sedimentologia da Plataforma Continental Interna entre as Prais Porto de Galinhas e Campos-Litoral Sul de Pernambuco, Brasil
The analysis of geomorphic and sedimentological characteristics of the inner continental shelf is an important propriety to studies of the coastal zone since they inform the conditions of the sea bottom, the predominant features and the types of associated sediments. Associated to morfodinamic study it can, for example, identify predisposed areas to erosive

11. Erosão laminar, atributos físico-químicos do solo e estrutura trófica da nematofauna em áreas do Reservatório da Usina Hidrelétrica Luiz Gonzaga
Naturally occurring erosion or in association with anthrop action (mainly) is a serious environmental problem, particularly in reservoir, because environmental degradation generate by erosive process is a risk for water availability, electric power generation, water supply and navigation. The present study aimed to characterize and correlate physical and che

12. Comparison of the erosive potential of two acidic sources in enamel and evaluation of treatments for prevention of dental erosion / Comparação do potencial erosivo de duas fontes ácidas sobre o esmalte e avaliação de métodos de controle da erosão dental
Dental erosion is defined as irreversible loss of dental hard tissue due to chemical processes without the involvement of microorganisms. The aim of this study was to compare in vitro the erosive potential of two acidic sources and evaluate the effectiveness of treatments for prevention of dental erosion. To compare the acidic sources, crowns of 5 unerupted
