1. Detection of seepage paths in small earth dams using the self-potential method (SP)
Abstract The application of geoelectric methods, such as induced polarization (IP), the electrical resistivity and the self-potential (SP), presents an important indirect study methodology in several areas of geology, such as mining, geotechnics and environmental geology. The present study deals with the results of the application of the self-potential metho

2. Checklist of the fishes from Jamari River basin, in areas under influence of dams, Rondônia, Brazil
Resumo: O rio Madeira é o mais extenso afluente do rio Amazonas e possui a maior biodiversidade de peixes do mundo. Em sua margem direita, o rio Madeira recebe o rio Jamari, no qual foi construída a primeira usina hidrelétrica (UHE) do estado de Rondônia, a UHE Samuel. Além desta, outros barramentos foram construídos no rio Jamari e em seus afluentes,

3. DAMS SAFETY INDEX (DSI): A REASSESSMENT OF THE PARAMETERS OF ANALYSIS
ABSTRACT Dams provide a water supply, irrigation and power generation. However, the economic, social and environmental impacts are serious when they rupture. It is important that dams continue to function properly and are constantly evaluated for their safety and functionality. Contrary to general belief, small dams are the ones that present the most problem

4. Long-term behavior of mortars produced with sulfide-bearing aggregates
ABSTRACT The variety of sulfides (inorganic compounds formed by combining sulfur with a metal element) presented in earth crust is not small, which makes it difficult to avoid the use of sulfide-bearing aggregates in the concrete, especially in places where another source of material is non-existent or economically impracticable, as is the case of dams. With

6. Litter Size Reduction Induces Metabolic and Histological Adjustments in Dams throughout Lactation with Early Effects on Offspring
In the present study we analyzed morphological and metabolic alterations in dams nursing small litters and their consequences to offspring throughout lactation. Offspring sizes were adjusted to Small Litter (SL, 3 pups/ dam) and Normal Litter (NL, 9 pups/ dam). Body weight, food intake, white adipose tissue (WAT) content, histological analysis of the pancrea

7. Successful Identification of Duck Genome Region Determining Desirable Uniformity of Meat Performance Traits
ABSTRACT The objective of this study was to identify genome regions determining duck meat performance traits with possible small variation. In total, 368 crossbred ducks of F2 generation obtained from two parental lines: Pekin-type ducks of Polish origin (A55) and Pekin-type ducks of French origin (GL-30) were recorded. The following seven traits were analyz

8. Comparative analysis of two different models of swimming applied to pregnant rats born small for pregnant age
ABSTRACT The aim of this study was to compare two models of swimming applied to pregnant rats born small for pregnancy age (SPA). Diabetes was chemically induced in adult female rats to develop an inadequate intrauterine environment, leading to birth of a SPA offspring. In adulthood, the female SPA rats were mated and submitted to different swimming programs

9. Effect of exercise on the maternal outcome in pregnancy of spontaneously hypertensive rats
PURPOSE:To evaluate the effect of exercise (swimming) on pregnancy in spontaneously hypertensive rats (SHR).METHODS: Thirty three pregnant female SHR were distributed into three groups (n=11 animals/group): SHR Control=non-exercised (sedentary); SHR Ex0 = exercised from day zero to day 20 of pregnancy; and SHR Ex7 = exercised from day 7 to 20 of pregnancy.

10. Effect of the heat curing on strength development of self-compacting mortars containing calcined silt of dams and Ground Brick Waste
The strength development of self-compacting mortars (SCM) containing calcined silt (CS) and ground brick waste (GWB) was investigated. The variables are the nature of addition (CS and GWB) in the binder and the heat curing at different temperatures (20 ºC and 60 ºC) at 7 and 14 days of curing. Two temperatures 20 and 60 ºC were applied to samples with int

11. Maternal protein restriction affects gene expression and enzyme activity of intestinal disaccharidases in adult rat offspring
This study investigated the consequences of intrauterine protein restriction on the gastrointestinal tract and particularly on the gene expression and activity of intestinal disaccharidases in the adult offspring. Wistar rat dams were fed isocaloric diets containing 6% protein (restricted, n = 8) or 17% protein (control, n = 8) throughout gestation. Male off

12. 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
