The science and application of the Earth observation system are receiving growing traction wider application, scope is becoming better owing to availability higher resolution satellite remote sensing products. A water quality monitoring model was developed using Sentinel-2 data set investigate spatiotemporal dynamics indicators at Koka Reservoir. L1C images were processed with an Atmospheric co...

The paper briefly describes the effects of diffusion and dispersion and other effects present during the oil displacement processes with miscible fluids, i.e. solvents. Recovery of oil is significantly improved during the application of such processes, but at the same time accompanied with decrease or even total loss of solvent slug. When designing such processes, particular attention should be...

saymareh dam and hydro-power plant are under construction on saymareh river in ravandi anticline, ilam province. during boring the power tunnel which crosses the anticline, a large volume of water was encountered. this volume of water was not observed in the past. considering the water quality of springs, water level of dam site piezometers, geological and hydrogeological inspections, isotope a...

Completion design for horizontal wells is typically performed using a geometric approach where the fracturing stages are evenly distributed along lateral length of well. However, this ignores intrinsic vertical and heterogeneity unconventional reservoirs, resulting in uneven production from hydraulic stages. An alternative to selectively complete intervals with similar superior reservoir qualit...

I measured physico-chemical properties and phytoplankton in the small, shallow tropical reservoir of Oyun (Offa, Nigeria) between January 2002 and December 2003. I identified 25 phytoplankton genera in three sampling stations. Bacillariophyceae dominated (75.3%), followed by Chlorophyceae (12.2%), Cyanobacteria (11.1%) and Desmidiaceae (0.73%). The high amount of nutrients (e.g. nitrate, phosph...

Recently, the vacuum technology has gained a significant relevance in many areas of basic research and applied science. Low-pressure environment of various quality is in common use in the top technology industrial applications. In the most cases, the leaks are the most common sources of deterioration in quality of vacuum. Therefore, the leak detection and consequential leak localization become ...

www.ejhp.org 54 INTRODUCTION Elastomeric devices are disposable infusion pumps mainly consisting of an elastomeric reservoir in which the solution to be administered is placed, and a flow restrictor system located in the administration tube set. The combination of both the pressure generated by the filled reservoir and the flow restrictor, sets a fixed flow rate of the solution according to Poi...
