Fermentation of lignocellulosic renewable resources and hydrogen production
(The Academy of Sciences and Arts of the Republic of Srpska, 2016)
Using cheap renewable raw materials such as lignocellulosic feedstock for hydrogen production by fermentation has great significance and potential to give a major contribution to future clean energy. Using hydrogen as a ...
Thermo-mechanical properties of rigid polyurethane foams with cement addition
(Society of Chemists and Technologists of Macedonia, 2016)
The parameters of foam preparation, such as addition of fillers, have a significant effect on the properties of polyurethane foams. The goal of this work was to study the effect of the cement addition on the thermo-mechanical ...
Superkritična ekstrakcija kao metoda za uklanjanje pesticida iz zemljišta
(Univerzitet u Kragujevcu, Agronomski fakultet u Čačku, 2016)
Cilj ovog rada je ukazivanje na mogućnost primene superkritične ekstrakcije sa ugljendioksidom na dekontaminaciju zemljišta zagađenih pesticidima (u ovom slučaju atrazinom). Analizirani rezultati ukazuju da se ova metoda ...
Analytical error during selection of reference state in thermodynamic of ideal gas / Analitička greška kod izbora referentnog stanja u termodinamici idealnog gasa
(Banja Luka, Republic of Srpska, Bosnia and Herzegovina : Tehnološki fakultet Univerziteta u Banjoj Luci, 2016)
The paper is based on the fact that the internal energy, enthalpy and enthropy as most important thermodynamic state functions, can not be determined in absolut terms without reference state slections. It is demonstrated ...
On some other preferred method for optimizing the welded joint / O jednoj pogodnoj metodi za optimizaciju zavarenog sklopa
(Savez inženjera i tehničara Srbije, Beograd, 2016)
The paper shows an example of performed optimization of sizes in terms of welding costs in a characteristic loaded welded joint. Hence, in the first stage, the variables and constant parameters are defined, and mathematical ...
