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. Primenjeni organski modifikator ...Nikola Stevanović, Aleksandar Mijatović, Aleksandar Lolić, Mario Zlatović, Rada Baošić.

Osnove mašinskog učenja u hidrogeologiji
Mašinsko učenje predstavlja skup metoda koje se u poslednje vreme koriste u brojnim naučnim oblastima i koje su uveliko promenile način na koji analiziramo podatke, pravimo predviđanja i rešavamo složene probleme. Poslednjih godina, mašinsko učenje se pokazalo kao moćan alat u svetu nauke, koji ima ogroman potencijal i u hidrogeologiji. Sa svojom sposobnošću da automatski uči iz ogromne količine podataka, mašinsko učenje otvara nove mogućnosti za rešavanje problema kao što su karakterizacija izdani, procena kvaliteta vode i predviđanje nivoa ...Ivan Drakulić, Dušan Polomčić, Jelena Ratković.

A fuzzy-based decision support model for effectiveness evaluation - a case study of examination of bulldozers
Effectiveness evaluation is one of the basic components of engineering asset management and maintenance engineering in general. Effectiveness is an overall concept representing a measurement of quality of service level for the analyzed engineering system. This concept contains a series of partial indicators relating to time in operation and time for maintenance activities, as well as functional properties of the system. This article describes the analysis and structuring of partial indicators, as well as the development of a model ...Miloš Tanasijević, Predrag Jovančić, Dejan Ivezić, Uglješa Bugarić, Radiša Đurić.

Geoheritage and Mining Heritage in the Promotion of Theme Parks: An Example of the National Park Đerdap (Carpathian-Balkan Thrust-And-Fold Belt, Eastern Serbia)
The National Park Đerdap (eastern Serbia, vicinity of the Danube River) occupies a segment of the Carpathian-Balkan fold-and-thrust belt and has a significant geoheritage potential, accounting for the impressive natural (geological) and cultural legacy. In addition to the extraordinary orogenic-type landscape or nappe-stacked mountainous configura tion, the region contains evidence of ancient mining activities, uncovered within its immediate neighbourhood.

Litijum u mineralnim vodama Srbije – potencijalna lekovita svojstva
Jana Štrbački (2022)Litijum je biološki aktivan mikroelement u ljudskom organizmu: u malim koncentracijama doprinosi pravilnom funkcionisanju pojedinih enzima, hormona i vitamina, dok se u većim, terapeutskim dozama, koristi za lečenje i prevenciju nekoliko psihijatrijskih poremećaja. Eksperimentalno je dokazano da su litijumske mineralne vode bioraspoloživi izvor ovog mikroelementa, u smislu obezbeđivanja njegovog preporučenog dnevnog unosa. Proučavanjem zakonomernosti raspodele litijuma u mineralnim vodama Srbije konstatovano je da barem 50 pojava sadrži koncentracije litijuma potrebne za unapređenje opšteg zdravstvenog stanja ljudi.Jana Štrbački.
