1. Upstream dam impacts on gilded catfish Brachyplatystoma rousseauxii (Siluriformes: Pimelodidae) in the Bolivian Amazon
ABSTRACT This paper explores the effects of two run-of-river dams (Jirau and Santo Antônio) built in cascade in the middle Madeira River (Brazil) on the interruption of long-distance migration routes of the gilded catfish (Brachyplatystoma rousseauxii). A participative monitoring system was set up to compare capture by commercial fishers approximately 1500

2. DNPM actions on the implementation of law 12.334/2010: from the ordinances and inspections to the SIGBM
Abstract As defined in PNSB - Law 12.334/2010 (Brasil, 2010), the DNPM, which manages the Brazilian mineral resources, is also responsible for overseeing the safety management of tailings dams in the country. The purpose of this article is to present the actions carried out in this context by the Department since the enactment of the Law in 2010, such as: el

3. Hydropower infrastructure and regional order making in the Sub-Mekong region
Abstract This paper conceptualizes the interplay between infrastructures and the reconstruction of regional order. We analyze the promotion of hydropower development in the Greater Mekong Sub-Region in relation to the potential emergence of a Chinese hegemony. Dams, electricity grids and monitoring systems have enabled cross-border linkages and dependencies,

4. Monitoring structures with optical fibers: infiltration detection
ABSTRACT The use of sensors and optical fibers for monitoring structures is continuously growing. Strains, displacements, accelerations, temperatures are just a few of the monitoring possibilities. In the case of dam structures, concrete face rockfill dams constitute a type of structures where the monitoring of water infiltrations is of particular interest.

5. Comunidade fitoplanctônica no monitoramento de rios do estado de São Paulo / Phytoplankton community in monitoring rivers of São Paulo state
There are few studies conducted on phytoplankton inhabiting the rivers. In São Paulo State many of the abstraction of water for public supply are located in lowland rivers and streams of low gradient and have a lot of dam built in their courses, and the presence of lateral lakes and small dams to capture water, contributing to the development of planktonic

6. Genetic characterization of the Neotropical catfish Pimelodus maculatus (Pimelodidae, Siluriformes) in the Upper Uruguay River
Freshwater fish present unique challenges when one attempts to understand the factors that determine the structure of their populations. Habitat fragmentation is a leading cause of population decline that threatens ecosystems worldwide. In this study, we investigated the conservation status of genetic variability in the Neotropical catfish (Pimelodus maculat

7. Investigação das alterações do consumo de alimento palatável induzidas por trauma precoce em ratas fêmeas
Introduction: Chronic stress in adulthood increases anxiety and prones the individuals to use palatable foods as ¿comfort foods¿, which seems to be mediated by an altered functioning of the hypothalamus-pituitary-adrenal axis (HPA). We aimed at verifying if early life stress also affects anxiety, feeding behavior and stress responses in adult female rats.

8. Limnological aspects of Little AÃudagem in Semiarid: Case Study of Dams Settlement May 25, Ce-Madalena / Aspectos limnolÃgicos da pequena aÃudagem no semiÃrido: estudo de caso dos aÃudes do Assentamento 25 de Maio, Madalena-Ce
The studies for small reservoirs in the semiarid northeast are still scarce, mainly in relation to water quality. This research aimed to discover the dynamic processes that occur in small reservoirs, to evaluate the multiple uses, the trophic state and water quality in small reservoirs representing the settlement on May 25. Carried out the systematic monitor

9. Verificação da aplicabilidade de tecnologia GNSS para o monitoramento de deslocamentos horizontais em barragens de concreto / Verification of the applicability of GNSS technology for monitoring the horizontal displacements of concrete dams
A segurança dos empreendimentos civis tem se tornado fator preponderante na viabilidade econômica das obras, uma vez que impacta o preço dos seguros cobrados. Dentro deste contexto, um dos aspectos importantes a serem considerados na elaboração de um projeto, notadamente no de grandes estruturas, é a instrumentação. Assim, ao se tratar com grandes ba

10. Avaliação da estrutura genética do surubim, Pseudoplatystoma corruscans (Actinopterygii: Siluriformes) como subsídio para o repovoamento do submédio São Francisco
The São Francisco River is 2700 km long, draining areas of the States of Minas Gerais, Goias, Bahia, Pernambuco, Alagoas, and Sergipe, as well as part of the Federal District. Before the construction of Paulo Afonso Hydroeletric Power Plant, waterfalls of Paulo Afonso (north-eastern Brazil) and its respective lakes already constituted a natural obstacle to

11. USE OF ELECTRO-LEVELS TO OBTAIN DEFLECTION AND BENDING MOMENT IN CONCRETE FACED ROCKFILL DAMS / APLICAÇÃO DE ELETRONÍVEIS PARA OBTENÇÃO DAS DEFLEXÕES E DOS MOMENTOS FLETORES NA FACE DE CONCRETO DE BARRAGENS DE ENROCAMENTO
This thesis describes the procedures involved in the montage, calibration and installation of 80 (eighty) electro-levels on the concrete face of Mazar¿s dam, located in the Paute river, southeast of Ecuador. This dam consists of a Concrete Face Rockfill Dam 166m high and it has upstream slopes of 1.4(h):1.0(v) and downstream slopes of 1.5(h):1.0(v). The roc

12. Uso das técnicas HCT e TDR no monitoramento do proceso de consolidação em reservatórios de barragens de rejeitos / Monitoring of consolidation process in deposits of tailings dam by TDR and HCT techniques
The mining industry generates a large amount of tailing, which is usually placed in tailing dams. To properly design these constructions, when the tailing is highly compressible, it is necessary to study the consolidation characteristics of this material by means of techniques that consider large deformations. This study aimed to establish the technique HCT
