The antioxidant properties of dried extracts from spent espresso coffee / Antioksidativna svojstva sušenih ekstrakata iz otpadne espreso kafe
(Association of Chemical Engineers of Serbia, 2013)
The importance of coffee waste utilization is based on the fact that it contains a large amount of biologically valuable components. Preparation of espresso coffee produces substantial quantities of polyphenolic acids that ...
Impermeable layers in landfill design / Prilog projektovanju vodonepropusnih slojeva deponija
(Association of Chemical Engineers of Serbia, 2013)
Landfills are complex systems that could potentially contaminate the environment. This needs to be prevented by providing impermeability during the landfill design. In this aim, the related regulations should be followed ...
Enzymatic synthesis and application of fatty acid ascorbyl esters / Enzimska sinteza i primena askorbil-estara masnih kiselina
(Association of Chemical Engineers of Serbia, 2013)
Fatty acid ascorbyl esters are liposoluble substances that possess good antioxidative properties. These compounds could be synthesized by using various acyl donors for acylation of vitamin C in reaction catalyzed by chemical ...
Modeling the kinetics of essential oil hydrodistillation from plant materials / Modelovanje kinetike hidrodestilacije etarskog ulja iz biljnih materijala
(Association of Chemical Engineers of Serbia, 2013)
The present work deals with the modeling of the kinetics of essential oils extraction from plant materials by water and steam distillation. The experimental data were obtained by studying the hydrodistillation kinetics of ...
Possibilities of utilization of co-products from corn grain ethanol and starch production / Mogućnosti iskorišćenja sporednih proizvoda prerade kukuruznog zrna iz proizvodnje etanola i skroba
(Association of Chemical Engineers of Serbia, 2013)
In recent decades, the expansion of alternative fuels production from crops traditionally used for food and animal feed has led to significant changes in the field of energy production, agriculture and food industry. Starch ...
Deformation behaviour of two continuously cooled vanadium microalloyed steels at liquid nitrogen temperature / Deformaciono ponašanje dva kontinuirano hlađena vanadijum mikrolegirana čelika na temperaturi tečnog azota
(Association of Chemical Engineers of Serbia, 2013)
The aim of this work was to establish the deformation behavior of two vanadium microalloyed medium carbon steels with different contents of carbon and titanium by tensile testing at 77 K. Samples were reheated at 1250°C ...
Thermal resistance testing of standard and protective filtering military garment on the burning napalm mixture / Testiranje termičke otpornosti standardne i filtrirajuće zaštitne vojničke uniforme na goruću napalm smešu
(Association of Chemical Engineers of Serbia, 2013)
Fires are an accompanying manifestation in modern weaponry use and in various accidents in peacetime. The standard military uniform is a primary barrier in protection of a soldier's body from all external influences, ...
Organophosphorus insecticides: Toxic effects and bioanalytical tests for evaluating toxicity during degradation processes / Organofosfatni insekticidi - toksični efekti i bioanalitički testovi za evaluaciju toksičnosti tokom procesa degradacije
(Association of Chemical Engineers of Serbia, 2013)
Organophosphorus insecticides have been the most applied group of insectcides for the last two decades. Their main toxic effects are related to irreversible inactivation of acetylcholinesterase (AChE). Actually, they ...
Uniaxial tension of drying sieves / Jednoosno zatezanje sušnih sita
(Association of Chemical Engineers of Serbia, 2013)
Although the literature contains numerous studies that have been developed to describe the nonlinear behavior of drying sieves operation, there are no papers that report deeper investigation of the drying sieve behavior ...
Functionalization of thermo-acid activated sepiolite by amine-silane and mercapto-silane for chromium(VI) adsorption from aqueous solutions / Adsorpcija hroma(VI) iz vodenih rastvora na termo-kiselinski aktiviranom sepiolitu funkcionalizovanom amino-silanom i merkapto-silanom
(Association of Chemical Engineers of Serbia, 2013)
Chromium(VI) adsorption from aqueous solutions onto thermo-acid activated sepiolite functionalized with (3-mercaptopropyl)trimethoxy-silane and [3-(2-aminoethylamino)propyl]trimethoxy-silane was investigated. Scanning ...
