The building of large dams in the Upper Paraná River basin altered the discharge regime at the Porto São José River section. The discharge regime has been altered since 1972, but the changes intensified after the Porto Primavera damming, in late 1998. Considering that discharge control affects the relationship between channel and floodplain, this work aimed to evaluate the intensity of the disc...

Most research projects produce generalizations to be pursued, conjectures to be proved, and special cases to be pondered–often meant to be dealt with at a later date. In this talk, I’ll give examples of such postponements from my own work that I hope will be interesting. Notation is pretty standard, I think. An [n; k]q code is a linear code of length n and dimension k over the …nite …eld Fq of ...

Cement grouting is an operation often carried out to consolidate and seal the rock mass in dam sites and tunnels. The quality and efficiency of a grouting operation depends on various factors such as water take, grout properties and grouting pressure. One of the parameters which have the highest effect is pressure since the application of excessive pressure causes the hydraulic fracture phenome...

Knowing that maternal diabetes is related to hyperglycemia and fetal hyperinsulinemia, which affect the lipid metabolism, the aim of this study was to evaluate the effects of Malpighia emarginata (acerola) juice on the glycemic and lipid profile of offspring of diabetic and nondiabetic Wistar rats. The adult offspring of non-diabetic dams and of dams with severe streptozotocin-induced diabetes ...

Descriptions of rock fabric and texture are of great value to geologists and petrophysicists as they can be used in facies analysis and in the interpretation of the environment of deposition. Grain shape and size information is used to correlate to petrophysical properties. They are also of importance to the production technologist for completion design and sand strength/failure prediction. Tex...

In this cross-sectional questionnaire-based study, we surveyed the attitudes toward, knowledge of, and use of rubber dams (RDs) among dentists in southern Nigeria. The questionnaire, which was distributed and collected by one of the authors, requested information on the dentists' background characteristics, attitudes, and knowledge. Data were analyzed with SPSS, and the chi-square was used to a...

check dams, are small dams in the watershed. these dams are constructed in susceptible areas to erosion due to reduce of flow velocity and erosion, control of sediment and flood in upstream of reservoir dams. these structures are made using wood, stone and cement, and gabion. these structures change the hydrological response of the watershed by reducing flow velocity, the channel slope and stor...

The potential of ecological restoration and green infrastructure has been long suggested in the literature as adaptation strategies for a changing climate, with an emphasis on revegetation and, more recently, carbon sequestration stormwater management. Tree planting “natural” detention structures such bioswales, basins, sediment traps are popular approaches. However, experimental verification p...

An embankment dam is a large artificial made by placing and compacting various compositions of soil, sand, clay or rock. One the rock fill dams located in Buleleng Regency, Bali Province, namely Tamblang Dam which planned to be utilized meet raw water needs Regency particular Province 510 liters/second, irrigates irrigated rice fields Bungkulan Bulian with an area 588 Ha, as micro hydro power g...

The study assessed the health quality of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) seed samples collected from formal and informal sector in Ethiopia and Syria. In Ethiopia, several seed-borne fungi were found on wheat samples: Cochliobolus sativum, Fusarium avenaceum, F. graminearum, F. nivale, F. poae and Septoria nodorum. C. sativum was predominant with 84% of samples...
