Pollution characteristics and potential ecological risk assessment of heavy metals in river sediments based on calculation of pollution indices
(Nova Science Publishers, Inc., 2015)
The presented study was carried out in order to evaluate risk assessment of selected heavy metals (Cd, Cu, Mn, Cr, Ni, Pb, Zn, Co and V) in river sediments in Serbia. The purpose of this chapter is to describe a new approach ...
Assessment of trace element contamination in the river and alluvial sediments using a sequential extraction technique and statistical analysis
(Nova Science Publishers, Inc., 2013)
This study presents the results of determination Cu, Cr, Zn, Pb, Cd, V, Ni, As and Hg content and assessment of their anthropogenic origin, mobility and contamination level in the river sediment (Tisa River and tributaries) ...
Environmental impacts of reservoirs
(Springer Netherlands, 2015)
The construction of reservoirs is one of the most important practices for the development and management of water resources. Many large reservoirs were built without a thorough or systematic evaluation of the long-term ...
Rheological behavior of hyperbranched polymers
(Nova Science Publishers, Inc., 2013)
Hyperbranched polymers represent intriguing class of dendritic polymers, which show remarkable, unique and different chemical and physical properties compared to their linear counterparts, as a result of their complex, ...
Synthesis and characterization of polystyrene based nanocomposites
(Nova Science Publishers, Inc., 2014)
Polystyrene, one of the most important material in the modern plastic industry and one of the major synthetic polymer in use today, offers an extremely broad range of applications, due to its good physical properties and ...
Electrodeposition of Copper Powders and Their Properties
(Springer, 2012)
A powder is a finely divided solid, smaller than 1,000 μm in its maximum dimension. A particle is defined as the smallest unit of a powder. The particles of a powder may assume various forms and sizes, whereas powders, an ...
Design of multi-pressure organic rankine cycles for waste heat recovery in site utility systems
(Elsevier, 2014)
This work addresses the design of Organic Rankine Cycle (ORC) processes used for power generation from low-grade heat available in site utility systems. The Exergy Composite Curves approach is used within a systemic ...
The synthesis of a sulfur-polymer matrix composite and morphological analysis of the samples in extreme conditions
(Nova Science Publishers, Inc., 2018)
Polymers had a great influence in the development of practical applications of materials and among the extensive variety of these compounds, organic polymers had a crucial role. Having in mind their wide practical application ...
Potential Energy Surface Evaluation and Fitting
(Elsevier, 2015)
The concept of potential energy surface (PES) for the motion of nuclei has been of central importance in molecular modeling ever since its development in the early 1960s and has been ubiquitous in theoretical, physical, ...
