Recent development of bioaugmentation methods for tobacco wastewater treatment
(University of Babes-Bolyai, Cluj-Napoca, 2015)
In production of cigarettes a lot of tobacco waste, with nicotine, goes into the environment. Hence, there is a need for an economic and efficient method to diminish the discharge of hazardous materials from tobacco ...
Preparation and properties of polymeric and composite bioresorbable barrier membranes
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
Bioresorbable barrier membranes have been widely used in dentistry and maxillofacial surgery. When the membranes are placed over bony defects and are closely adapted by the surrounding bone face, an environment that prevents ...
Landfill closure best available technique development: case study of Serbia
(Journal of Environmental Protection and Ecology, 2020)
Waste disposal is the last but inevitable step in waste management and it significantly effects the environment. According to the Serbian Waste Management Strategy, disposal sites should be closed and new, sanitary regional ...
The influence of bonding agents in improving interactionsin composite propellants determined using image analysis
(Wiley, Hoboken, 2008)
Binder-oxidizer interactions in rocket composite propellants can be improved using adequate bonding agents. In the present work, the effectiveness of different 1,3,5-trisubstituted isocyanurates was determined by stereo ...
Linear free energy relationships of the H-1 and C-13 NMR chemical shifts in 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)pyridones
(Elsevier Science Bv, Amsterdam, 2009)
Linear free energy relationships (LFER) were applied to the H-1 and C-13 NMR chemical shifts in 3-cyano-4(substituted phenyl)-6-phenyl-2(1H)pyridones. The correlation analysis for the substituent-induced chemical shifts ...
Implementation of neural networks for classification of moss and lichen samples on the basis of gamma-ray spectrometric analysis
(Springer, Dordrecht, 2007)
Mosses and lichens have an important role in biomonitoring. The objective of this study is to develop a neural network model to classify these plants according to geographical origin. A three-layer feed-forward neural ...
Effect of the physicochemical properties of N,N-Disubstituted-2-phenylacetamide derivatives on their retention behavior in RP-TLC
(Akademiai Kiado Zrt, Budapest, 2007)
The chromatographic behavior of some N,N-disubstituted-2-phenylacetamide derivatives has been studied on the chemically bonded stationary phase RP-C-18 with acetone, acetonitrile, tetrahydrofuran, dioxane, methanol, ethanol, ...
Mass transfer and fluid flow visualization in packed and fluidized beds by the adsorption method
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Mass transfer coefficient (j (D) ) between fluid and column wall in liquid packed and fluidized beds of spherical inert particle has been studied experimentally using adsorption method. Experiments were conducted in column ...
Applications of non-linear frequency response for investigation of adsorption systems
(Soc Chemists Technologists Madeconia, Skopje, 2009)
Two main directions of application of nonlinear frequency response and the concept of higher order frequency response functions (FRFs) in investigation of adsorption systems are presented, one for development of novel ...
Nonlinear dynamics of brewing yeast cell growth in alginate micro-beads
(7th Conference of the Yugoslav Materials Research Society - Recent Developments in Advanced Materials and Processes, YUCOMAT VII, 2006)
The nonlinear dynamics of brewing yeast cell growth in porous Ca-alginate matrices is considered experimentally and theoretically. The applications of alginate matrices include the reduction of internal mass transfer ...
