Fizičko-hemijsko raspadanje krečnjaka ugrađenih u objekte Beogradske tvrđave i mogućnost konsolidacije
Maja Z. Franković (2022)Beogradska tvrđava, spomenik kulture od izuzetnog značaja za Republiku Srbiju, izgrađena je od krečnjaka badenske starosti. Njihova litološka heterogenost, u sadejstvu sa uticajima okruženja, rezultira visokim intenzitetima raspadanja. Korelacijom intrinzičnih sa ekstrinzičnim faktorima, definisani su fizičko-hemijski procesi raspadanja ugrađenih mikrofacija krečnjaka. Aplikacijom neorganskih konsolidanata na karbonatnoj bazi (nano-kreča i Ca-acetoacetata) i alkoksisilana, te korelacijom fizičko-mehaničkih svojstava pre i nakon tretmana, ispitana je efektivnost u pogledu zaustavljanja dekohezije krečnjaka.

The oil industry and climate changes
Dejan Radivojević (2020)Uprkos tome što je problem klimatskih promena poznat dugi niz godina i dalje veliki broj ljudi poistovećuje pojam vremenskih prilika sa klimom ne uzimajući u obzir različitu dužinu njihovog trajanja. U medijima se vrlo često mogu naći katastrofična predviđanja vezana za zagrevanje naše planete usled neodgovornog ponašanja čoveka. Sa druge strane geolozi znaju da je tokom geološke prošlosti naše planete bilo mnogo toplijih intervala od današnjih kao i da ti intervali nisu neminovno rezultovali masovnim izumiranjem živog sveta već su ......

Legal framework for recultivation of degraded areas caused by mining exploitation
Radmila Gaćina (2023)Prilikom površinske i podzemne eksploatacije uglja eksploatacioni sistemi oštećuju veće ili manje površine zemljišta. Iskustva pokazuju da su oštećenja zemljišta znatno veća kod površinske eksploatacije, gde je prostora degradiran ne samo u konturi rudnika i okoline, već se promene takođe dešavaju u prirodnom okruženju. U članku su predstavljeni rezultati studije zakonskih okvira rekultivacije u nekim zemljama sveta i u Srbiji.

Modeliranje i simulacija energetske tranzicije u sektoru domaćinstava
Boban S. Pavlović (2022)Aktuelnu energetsku tranziciju odlikuje ubrzanje procesa dekarbonizacije energetskih sistema, unapređenje energetske efikasnosti, razvoj čistijih tehnologija baziranih na obnovljivim izvorima energije i održivije korišćenje prirodnih resursa. Da bi se napravio ovako krupan zaokret u postojećim energetskim sistemima, osim promene postojećih tehnologija, potrebno je u planiranje energetske tranzicije uključiti i političke, sociološke, ekonomske i ekološke aspekte, a pre svega obrasce ponašanja i donošenja odluka krajnjih potrošača.

Geomorfološke posledice poplava 2014. godine u karstu Dževrinske grede (istočna Srbija)
The year 2014 was the year of extremely large floods in Serbia. The territories of municipalities Kladovo and Negotin, along the Danube course in Eastern Serbia, were among the worst affected, mostly by flash floods. The karst ridge of Dževrinska Greda, a typical contact karst and stripe karst environment formed within Upper Jurassic limestones, suffered significant morphological changes in terms of heavy washout of sediments on one hand (in fluviokarstic gorges and active cave passages), and on the other ...Jelena Ćalić, Dejan Jeremić, Ana Mladenović.

Asset management and condition monitoring on maintenance of mining equipment lignite mines
Predrag Jovančić (2016)Maintenance strategy, once set, is not permanent. This strategy should be adapted and altered according to the findings, achieved results, variation of mine product prices, changes in the region etc. On the other hand, maintenance strategy should be: safe operation, higher productivity, reduced costs and functionality of complete system. Asset management represents activities through which mine achieves the optimal and sustainable management of its property, in order to meet the plan - realization of production with optimized costs. Therefore, ...Predrag Jovančić.

The different approaches in seismic stratigraphy interpretation
Dejan Radivojević (2018)U tekstu su prikazana dva osnovna pristupa u seizmostratigrafskoj interpretaciji. Prvi kao polaznu osnovu ima seizmičke sekcije, čija se interpretacija u kasnijoj fazi koreliše sa bušotinskim podacima. Drugi u prvoj fazi analizira podatke dobijene dubokim bušenjem koji se kasnije korelišu sa seizmičkim sekcijama. Prikazan je hronološki redosled i objašnjen postupak pri seizmostratigrafskoj interpretaciji oba pristupa. Ovakav način interpretacije omogućio je naftnim kompanijama detaljnije i preciznije sagledavanje geoloških odnosa, smanjenje rizika istraživanja i racionalnije projektovanje razradnih bušotina.seizmostratigrafija, istraživanje nafte i gasa, karakteristične seizmičke sekvence, seiz-mofacijalna analiza... 26, p 165-184.

Sitni, ali bitni: uloga sitnih sisara, herpetofaune i mekušaca u rekonstrukciji pleistocenskih paleosredina
Fosilni ostaci životinja i biljaka imaju važnu ulogu u rekonstrukciji pleistocenskih paleosredina. U ovom radu opisan je značaj tri grupe životinja: sitnih sisara, herpetofaune I mekušaca. Mada je za rekonstrukciju važan sastav čitave asocijacije, nalasci pojedinih vrsta mogu biti dovoljno indikativni da otkriju tip staništa ili klimatske uslove. Posebnu teškoću pri rekonstrukciji paleosredina u Srbiji predstavlja činjenica da klimatske promene na Balkanskom poluostrvu nisu bile tako oštre kao u srednjoj i zapadnoj Evropi, pa ne postoji drastična razlika u ...... archacology, Environmental Archacology.

Burnishing Versus Smoothing In Ceramic Surface Finishing: A Sem Study
From the Neolithic up to the present, people have used various methods to improve the surface of ceramic objects. In this study, we look specifically at smoothing and pattern burnishing of ceramics produced today by traditional methods. Optical microscopy and SEM show specific surface changes. Smoothing results in an irregular surface, which causes diffused reflection of light. Burnishing produces an even and compact surface, which causes specular reflection and lustre. The results can be used to infer methods of ...Ionescu Corina, Volker Hoeck, Crandell Otis N., Šarić Kristina.

Simple 2D gravity–density inversion for the modeling of the basin basement: example from the Banat area, Serbia
We have developed a technique to calculate lateral density distribution of the sedimentary basin basement by combining linear gravity–density inversion and 2D forward modeling. The procedure requires gravity anomaly data, depth-to-basement data and density data for the sediments (density–depth distribution). Gravity efect of density variations in the basement was extracted from the total gravity anomaly by removing the joint efect of the sediments with vertical density variations and homogeneous basement of average density contrast (calculated by 2D modeling).

Atmospheric exposure vs burying: influences on damage intensity of built-in kersantite in the monument of the Small Staircase (Belgrade, Serbia)
Proučavan je efekat „zatrpanog kamena“ na intenzitet procesa degradacije prisutnih na kersantitu koji je ugrađen u spomenik Malo stepenište. Istraživanja su vršena na uzorcima stene iz kamenoloma i na oštećenim kamenim blokovima ugrađenim u spomenik. Dok su neki delovi stepeništa bili pod zemljom 90 godina, većina kamenih elemenata je bila izložena različitim uslovima sredine i antropogenim uticajima. Urađeno je detaljno mapiranje trenutnog stanja spomenika kako bi se istražio uticaj “zatrpavanja” i kompleksne geometrije spomenika na tip propadanja i variranje ...Nevenka Novaković, Predrag Dabić, Vesna Matović.
