The Flow Conditions in the Epikarst Zone of a Karst Aquifer. Case Study: Suva planina Mt., East Serbia
Branislav Petrović (2022)The epikarst as a part of the karst aquifer represents a complex point of contact and mixing of unconsolidated material from the terrain surface, carbonate rocks altered by “corrosive” water, flora and fauna (and remains of), which is partially saturated with groundwater. Recharge of karst aquifers, usually, occurs via the unsaturated zone which uppermost part could be epikarst zone. Significant amounts of (plant accessible) water, and other solutes and particles, can be stored in this zone for extended periods ...Branislav Petrović.

The influence of Al<sup>3+</sup>ion on porcine pepsin activity<i>in vitro</i>
The in vitro effect of Al3þ ions in the concentration range 1.7·1026M–8.7·1023M on pepsin activity at pH 2, via kinetic parameters and its electrophoretic mobility was evaluated. Kinetic study demonstrated the existence of an activation effect of Al3þ at pH 2 on pepsin molecule. Kinetic analysis with respect to concentrations of haemoglobin showed that Al3þ ions increase the maximal velocity (Vmax) and kcat values rather than apparent affinity for substrate (KS) implying the non-competitive nature of activation which indicated ...Vesna M.

Automatic construction of a morphological dictionary of multi-word units
The development of a comprehensive morphological dictionary of multi-word units for Serbian is a very demanding task, due to the complexity of Serbian morphology. Manual production of such a dictionary proved to be extremely time-consuming. In this paper we present a procedure that automatically produces dictionary lemmas for a given list of multi-word units. To accomplish this task the procedure relies on data in e-dictionaries of Serbian simple words, which are already well developed. We also offer an evaluation ...electronic dictionary, Serbian, morphology, inflection, multiwordn units, noun phrases, query expansionCvetana Krstev, Ranka Stanković, Ivan Obradović, Duško Vitas, Miloš Utvić.

Business Models for Small-scale Biomass Projects Development
Biomass is recognized as the most promising renewable energy source in Serbia. The share of biomass in Serbian final energy consumption is over 10%, but mostly related to traditional use in stoves and ovens. One of the main obstacles for wider implementation of contemporary biomass facilities is the inexperience of consumers and stakeholders in the implementation of “innovative” business models, especially in the cases of small-scale projects. In this paper, three different business models (public utility company, energy cooperative ...Dejan Ivezić, Miodrag Gluščević, Marija Živković.

Utilizing sewage wastewater heat in district heating systems in Serbia: effects on sustainability
Marija Živković, Dejan Ivezić (2021)Transformation of the heating sector is recognized as being essential for ensuring reliable and afordable energy services provided with reduced consumption of energy sources and diminished impact on the environment and less import dependency. The possibility of utilizing energy sources that otherwise would be wasted needs to be considered and treated as a big advantage of district heating systems. Despite many advantages, sewage wastewater heat is still a mostly unused resource at the global level and a totally unused ...рекуперација топлоте из отпадних вода, систем даљинског грејања, топлотне пумпе, енергетске уштеде, емисија угљендиоксида, енергетска безбедност, СрбијаMarija Živković, Dejan Ivezić.

Examination of the possibility of obtaining pyrite concentrate from the flotation tailings of the Lece mine
Рудник Леце је карактеристичан по томе што у флотацијским концентратима олова и цинка као корисну примену има злато и сребро. Практично од отварања рудника и флотације трају истраживања и борба за што боље технолошке показатеље на сва четири платива метала (олово, цинк, злато и сребро) посебно на злату. Овај рад представља допринос тој борби у циљу повећања искоришћења злата. Како је начин појављивања злата веома различит (самородно, са оловом и цинком, са пиритом и кварцом) то је и технолошка ...Predrag Lazić, Đurica Nikšić, Dejan Stojanović, Tamara Stojanović.

Witness of the history: A hundred years old the geological hammer of Jovan Zujovic
Ljupko Rundić (2021)Током обележавања тридесет година постојања и рада Српског геолошког друштва 10. фебруара 1921. године, у знак великог поштовања према академику Јовану Жујовићу, председнику и оснивачу Српског геолошког друштва и српске геолошке школе, чланови СГД поклонили су му јединствени геолошки чекић са угравираном посветом и својим потписима. Током протеклих стотину година, многе генерације геолога проналазиле су инспирацију гледајући чекић и делећи ову причу с великим пијететом.
