Application of Membrane Technology for Separation CO2 from Natural Gas
Natural gas consists of a mixture of hydrocarbons with the largest share of methane, and non-hydrocarbon impure components such as N2, CO2 and H2S. In order to fulfill the gas market requirements, it is necessary to separate these unwanted components from the natural gas stream. There are several available technologies for the separation of CO2 from natural gas, such as: polymeric membranes, cryogenic distillation, absorption and adsorption. In this paper is presented the mechanism of CO2 separation using membrane technology, ...Lola Tomić, Dušan Danilović, Vesna Karović Maričić, Branko Leković, Miroslav Crnogorac.

Malathion-induced inhibition of human plasma cholinesterase studied by the fluorescence spectroscopy method
The in vitro effect of technical grade malathion was assessed via the kinetic parameters of human plasma butyrylcholinesterase (BChE) using N-methylindoxyl acetate as a substrate for BChE. An inhibitor kinetics study demonstrated the existence of a biphasic inhibition curve, indicating high- and low-affinity binding sites of malathion. The IC50 values as calculated from the experimental inhibition curves were 1.33 × 10–9 and 1.48 × 10–5 M for the high- and low-affinity binding sites, respectively; Hill’s analysis gave 1.29 × ...V.

Jovanovići deposit: New formation type of dimension and construction stone in Montenegro
Darko Božović, Vladimir Simić (2023)Arhitektonsko-građevinski kamen predstavlja jednu od najznačajnijih nemetaličnih mineralnih sirovina Crne Gore, sa brojnim istraženim ležištima karbonatnih mineralnih sirovina od kojih su neka u eksploataciji, među kojima je područje Bjelopavlića najznačajnije. Formaciono-mineragenetskom analizom karbonatnih sedimenata rudnog rejona Bjelopavlića izdvojeno je više formacionih tipova karbonatnih sirovina, među kojima i formacioni tip Jovanovići, kao novi formacioni tip ukrasnog kamena u Crnoj Gori. U radu je dat prikaz rezultata višegodišnje formaciono-mineragenetske analize izvršene na području rudnog rejona Bjelopavlića, geološke karakteristike formacionog tipa Jovanovići, ...Darko Božović, Vladimir Simić.

Application of Thermal Imaging in Surface Mining
Milanka Negovanović (2022)Termalno snimanje se sve više koristi u rudarskoj industriji kao jedan od dijagnostičkih alata za praćenje određenih proizvodnih procesa, kao i stanja opreme i mašina. Predstavlja nedestruktivnu i beskontaktnu metodu ispitivanja koja omogućava rano otkrivanje problema, planiranje održavanja sa minimalnim kvarovima, sprečavanje neplaniranih poremećaja, posmatranje materijala u nepristupačnim ili opasnim područjima i poboljšanje bezbednosti i produktivnosti. Termalno snimanje koristi specijalizovane termalne kamere sa unutrašnjim detektorima koji identifikuju veoma male temperaturne varijacije i proizvode sliku tog nevidljivog infracrvenog ili toplotnog ...Termalno snimanje, nedestruktivne metode testiranja, površinska eksploatacija, termalne kamere, rudarske operacijeMilanka Negovanović.

Huang, Seimi Chu, Draženko Nenadić, Predrag Radović, Joshua Lindal, Mirjana Roksandić (2022)Recent research in the southern Central Balkans has resulted in the discovery of the first Middle Paleolithic sites in this region. Systematic excavations of Velika and Mala Balanica, and Peˇsturina (southern Serbia) revealed assemblages of Middle Paleolithic artifacts associated with hominin fossils and animal bones. This paper focuses on Pesturina Layer 4, radiometrically and biostratigraphically dated to Marine Isotope Stage (MIS) 5, which yielded traces of temporary hunting camps. The remains of large ungulate prey are associated with predominantly ...Dušan Mihailović, Stefan Milošević, Bonnie A.B. Blackwell, Norbert Mercier, Susan M. Mentzer, Christopher E. Miller, Mike W.

Prilog poznavanju režima i bilansa voda reke Resave
Sliv Resave zauzima područje između reke Velike Morave i obronaka Kučajsko-beljaničkih planina. Sliv i režim ove reke kontroliše se dvema hidrološkim stanicama: Manastir Manasija (slivno područje u iznosu od 388 km2) i Svilajnac (681 km2). Za potrebe analize režima voda reke Resave i uticaja padavina na formiranje oticaja sa njenog sliva preuzeti su podaci o padavinama sa meteorološke stanice Crni Vrh (1037 m nm) koji odslikava režim gornjeg dela sliva ove reke, i meteorološke stanice Smederevska ...Marina Mitrašinović, Vesna Ristić Vakanjac, Saša Milanović, Ljiljana Vasić, Dušan Polomčić.
