Ecological risk assessment for different macrophytes and fish species in reservoirs using biota-sediment accumulation factors as a useful tool
(Elsevier Ltd, 2018)
Metal content was evaluated in the sediment, macrophytes and fish in the Medjuvrtje reservoir (Western Serbia). Concentrations of 16 trace elements (Ag; Al; As; B; Ba; Cd; Co; Cr; Cu; Fe; Li; Mn; Ni; Pb; Sr; Zn) were ...
Multi-Temporal Analysis of Mean Annual and Seasonal Stream Flow Trends, Including Periodicity and Multiple Non-Linear Regression
(Kluwer Academic Publishers, 2014)
Global warming affects the hydrological cycle and the long-term water budget of river basins. Flow variations have been noticed in the Danube River Basin, especially in its south-western parts where a downward trend in ...
A joint stochastic-deterministic approach for long-term and short-term modelling of monthly flow rates
(Elsevier B.V., 2017)
The authors present a detailed procedure for modelling of mean monthly flow time-series using records of the Great Morava River (Serbia). The proposed procedure overcomes a major challenge of other available methods by ...
Improvement of chemical control in the water-steam cycle of thermal power plants
(Applied Thermal Engineering, 2011)
A more effective chemical control in the water-steam cycle (WSC) of thermal power plants (TPP) is proposed in this paper. Minimization of corrosion effects by the production of ultra pure water and its strict control is ...
Separation of water-in-oil emulsions by freeze/thaw method and microwave radiation
(Elsevier, 2006)
In this paper, the demulsification has been achieved with the use of freeze/thaw (F/T) method and microwave radiation (MWR). The object of investigation were emulsion samples prepared by mixing the metal-working-oil, FESOL ...
Bed-mounted Electro Magnetic meters: Implications for robust velocity measurement in Urban Drainage systems
(Elsevier B.V., 2018)
Flow monitoring in Urban Drainage Systems (UDS) is required for a successful system control and operational assessment. Commonly used methods can lead to erroneous results in partially filled pipes and hostile environmental ...
Towards harmonisation of image velocimetry techniques for river surface velocity observations
(Copernicus Publications, 2020)
Since the turn of the 21st century, image-based velocimetry techniques have become an increasingly popular approach for determining open-channel flow in a range of hydrological settings across Europe and beyond. Simultaneously, ...
Governing factors for motor oil removal from water with different sorption materials
(Journal of Hazardous Materials, 2008)
This paper has been focused on the sorbent efficiency for motor oil removal from water. Two types of sorbents were investigated: organic and inorganic. Natural wool fibers (NWFs) and recycled-wool-based nonwoven material ...
Multicriteria optimization of natural and recycled aggregate concrete for structural use
(Elsevier Ltd, 2015)
Recycling of concrete waste to produce recycled concrete aggregates (RCA) and its use in the production of structural concrete is the way towards reducing the depletion of natural mineral resources and the amount of ...
Hydro energy potential of cooling water at the thermal power plant
(Elsevier Ltd, 2011)
The hydro energy of the gravity water flow from the coal-fired thermal power plant units to the river in an open cooling system of turbine condensers is determined. On the basis of statistical data for a long time period, ...
