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 ...
The effect of different extractants on lead desorption from a natural mineral
(Elsevier B.V., 2015)
Natural minerals, such as quartz, clinoptilolite and calcite, are useful as sorbents for various applications, but their content of heavy metals ions is the most problematic obstacle to their application. Before their ...
GIS Based Estimation of Sediment Discharge and Areas of Soil Erosion and Deposition for the Torrential Lukovska River Catchment in Serbia
(Kluwer Academic Publishers, 2014)
In the present study the SHETRAN river basin modelling system was used in conjunction with Geographic Information System (GIS) to estimate potential erosion and deposition rates within the catchment and the concentrations ...
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 ...
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 ...
Simulation of transcritical flow in pipe/channel networks
(ASCE - American Society of Civil Engineers, 2004)
Using finite difference methods in conjunction with the reduced momentum equation and applying boundary condition structure inherent to subcritical flow to all regimes, is an approach that enables efficient numerical ...
Broadening the urban sustainable energy diapason through energy recovery from waste: A feasibility study for the capital of Serbia
(Elsevier Ltd, 2017)
Metropolitan areas are large consumers of energy and there is a growing need to broaden the urban sustainable energy diapason and increase the share of renewable and sustainable energy in overall energy consumption. This ...
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 ...
