Distribution of major and trace elements in the Kovin lignite (Serbia)
Dragana Životić, Olga Cvetković, Predrag Vulić, Ivan Gržetić, Vladimir Simić, Konstantin Ilijević, Biljana Dojčinović, Suzana Erić, Bogdan Radić, Sanja Stojadinović, Snežana Trifunović (2019)geochemical and mineralogical study was performed on lignite samples from the Upper Miocene Kovin deposit, hosting three coal seams. The Kovin lignite is characterized by high moisture content, medium to high ash yield, medium to high sulphur content and a relatively low gross and net calorific value. The mineralogical composition, and major and trace element contents were determined by X-ray diffraction, scanning electron microscopy with energy dispersive Xray spectroscopy (SEM-EDS) analyses, and inductively coupled plasma optical emission spectrometry (ICP-OES). ...... element distribution in iron disulfides in coal: a geochemi cal review.– International Journal of Coal Geology, 94, 32–43. doi: 10.1016/j. coal.2011.10.011 KORTENSKI, J. & SOTIROV, A.

Хидротермалне промене у издвојеним стратиграфским јединицама у бушотини јужно од Бора
Павле Јовичић (2024)Анализом уступљених узорака из истражне бушотине јужно од Бора, од стране компаније Serbia Zijin Mining, утврђене су хидротермалне промене (алтерације) које прате стратиграфске чланове набушене самом бушотином. Установљене алтерације директно осликавају класично развиће порфирског Cu система, при чему је указано на њихову повезаност са минерализацијом, као и на потенцијалност самог истражног простора којем изабрана бушотина припада.Павле Јовичић.

Hidrogeohemijska valorizacija esencijalnih mikroelemenata mineralnih voda Srbije
Jana S. Stojković (2013-09-25)Mineralne vode još od davnina privlače pažnju ljudi i to kako u pogledu istraživanja iproučavanja, tako i u pogledu njihovog iskorišćavanja. Naročito je važno poznavanjesadržaja mikroelemenata u njima, jer su to komponente njihovog hemijskog sastavakoje ih odvajaju od tzv. „običnih“ malomineralizovanih voda.U ovom radu proučavani su odabrani esencijalni mikroelementi (fluor, bor, litijum,kalijum, stroncijum i silicijum), u mineralnim vodama Srbije, pri čemu je analiziranopreko 130 uzoraka mineralnih voda iz različitih geoloških sredina, to jest hidrogeološkihrejona.

Određivanje zbijenosti starog komunalnog otpada
Bez obzira na savremene tretmane komunalnog otpada u svetu, u Srbiji je i dalje najčešći vid odlaganja na komunalne deponije, pa zbijanje otpada predstavlja jednu od ključnih faza formiranja deponije. Na ovaj način znatno se smanjuje zapremina otpada, ubrzava proces degradacije i produžava radni vek deponije. Zbog toga su geotehničke karakteristike komunalnog otpada prilikom zbijanja, veoma bitne kako u fazi projektovanja tako i u fazi izgradnje deponije i optimizacije prostora. Tu se pre svega misli na maksimalnu suvu zapreminsku ...Jovana Janković, Dragoslav Rakić, Irena Basarić Ikodinović, Tina Đurić.

Improving Document Retrieval in Large Domain Specific Textual Databases Using Lexical Resources
Large collections of textual documents represent an example of big data that requires the solution of three basic problems: the representation of documents, the representation of information needs and the matching of the two representations.

Production of morphological dictionaries of multi-word units using a multipurpose tool
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, multi-word units, noun phrases, query expansion... a ’ Gen= ‘=$g />j f e l o v a k u l a ’> j s k i r a d o v i ’>

Influence of mono- and two-component organic modifiers on determination of lipophilicity of tetradentate Schiff bases
Ispitivani su uticaji primene mono- i dvokomponentnih organskih modifikatora na određivanje lipofilnosti 12 tetradentatnih Šifovih baza metodom reverzno-fazne tankoslojne hromatografije. Osnovni cilj je da se proceni tip interakcije između posmatranih jedinjenja i komponenti primenjenih hromatografskih sistema i uspostavi neki obrazac ponašanja kako bi se lakše izabrala kombinacija organskih modifikatora koji će simulirati interakciju u biološkim sistemima na osnovu činjenica da iste osnovne intermolekularne interakcije su odgovorne za ponašanje supstanci i u biološkom i u hromatografskom sistemu.

Приказ резултата истраживања рудне жице 43 на хоризонту -100 рудника ''Леце''
Цветковић Марко (2024)Лежиште олова и цинка са пратећим златом и сребром интезивно се експлоатише од 1953. године. Експлоатација се промењивим интезитетом одвијала до 2001. године, када престаје због организационо-финансијских проблема. После приватизације рудника Концерн ''Фармаком-МБ'' из Шапца постаје власник рудника и покреће низ активности на санирању стања и обнављању производње. Од 2010. године поново почиње интезивна експлоатација и прерада руде.

Izdvajanje vode iz prirodnog gasa

Sama pojava vode u vidu vlage u gasu je pokazatelj lošeg kvaliteta gasa. parametri koji mogu dovesti do lošeg kvaliteta prirodnog gasa kao pokazatelj je Wobbe index.U okviru istraživanja u master radu glavni problem funkcionisanja na KPG Paliću predstavlja vlaga u gasu,takođe se može zaključiti da kvalitet gasa zavisi od Wobbe indeksa odnosno, što je Wobbe veći, čistiji je gas, ili ......

Availability as a dimension of energy security in the Republic of Serbia
Boban Pavlović, Dejan Ivezić (2016)There is a range of modern approaches and models in literature for the evaluation and determination of energy security, which are based on different parameters and indicators. For most of them, a common characteristic is emphasizing the avail ability of energy, as an important dimension for ensuring energy security. In this paper, concise overview of Serbian energy sectors is given and appropriate energy indicators are defined and determined. Selected indicators provide insight into the main components that characterize availability ...... norm 1 , , 1, ,ij n ij i a A i j n a = = = ∑ (19) Next step is to determinate the criteria weight vector, wi, which is built by averaging the entries on each row of the normalised pairwise comparison matrix, Anorm: 1 , , 1,1 , n i ij j i jw na n = == ∑ (20) Obtained values ...

Integrative GHG Assessment in Oil and Gas Industry
Reducing greenhouse gas emissions is one of the main targets of national strategies in European countries. As a main contributor to emissions, the energy sector is recognized as the most promising to apply measures and actions aimed to decrease GHG emissions. The Oil and Gas industry as a significant contributor to global greenhouse gas emissions is facing a growing need for estimating, mitigating, and reducing the impact of their operations on the atmosphere to stay competitive in a newly ......
