Gate Road Support Deformation Forecasting Based on Multivariate Singular Spectrum Analysis and Fuzzy Time Series
Luka Crnogorac, Rade Tokalić, Zoran Gligorić, Aleksandar Milutinović, Suzana Lutovac, Aleksandar Ganić (2021)Underground mining engineers and planners in our country are faced with extremely difficult working conditions and a continuous shortage of money. Production disruptions are frequent and can sometimes last more than a week. During this time, gate road support is additionally exposed to rock stress and the result is its progressive deformation and the loss of functionality of gate roads. In such an environment, it is necessary to develop a low-cost methodology to maintain a gate road support system. ...deformacije podgrade, lasersko skeniranje, višekanalna singularna spektralna analiza, prognoza, klasterisanje fuzzy vremenskih serija... in Tunnel Surrounding Rock.

The use of biological markers in determination of origin and type of organic matter in the Tisza river sediments
Snežana Štrbac, Gordana Gajica, Aleksandra Šajnović, Nebojša Vasić, Ksenija Stojanović, Branimir Jovančićević (2013)The objective of the study was to determine the origin and type of organic matter (OM) of the Tisza recent sediments along the distance of 153 km through the territory of Serbia. For this purpose group organic-geochemical parameters and biomarker compositions were used. All samples contain approximately same amount of OM, which was deposited under uniform, slightly reducing conditions. Based on the distribution of n-alkanes, the origin and type of OM could not be precisely estimated. However, n-alkane patterns ...... Bechtel, R. F. Sachsenhofer, I. Kolcon, R. Gratzer, A. Otto, W.

Šeklić, Snežana Sretenović, Marija Ilić, Jovana Bogojeski (2023)Cancer remains one of the world's deadliest diseases, claiming many lives each day. Transition metal complexes are leading candidates in developing anticancer agens with cisplatin used in chemotherapy worldwide. Copper, an endogenous metal in the human body, is especially attractive because of its typical redox biological activities and a relatively strong affinity to nucleobases.

The challenges for Z-generation geologists
Dejan Radivojević (2022)Nastupajuća generacija geologa suočava se sa nekim problemima koji su poznati i njihovim prethodnicima, ali takođe i sa do sada novim i nepoznatim izazovima. Činjenica da mnogi geologiju povezuju sa „prljavim“ industrijama u kojima će biti sve manje prilika za zaposlenje u vreme kada se teži čistoj vodi, zemljištu i vazduhu kao i to da je smatraju zastarelom u sadašnje vreme brzog tehnološkog razvoja dovela je do velikog pada interesovanja za studije geologije svuda u svetu.

Dehydroicetexanes in sediments and crude oils: Possible markers for Cupressoideae
Hans Peter Nytoft, Geir Kildahl-Andersen, Sofie Lindström, Frode Rise, Achim Bechtel, Danica Mitrović, Nataša Đoković, Dragana Životić, Ksenija A. Stojanović (2019)Two previously unidentified dehydroabietane isomers were isolated from Miocene Serbian lignite and Rhaetian (Late Triassic) coaly mudstones from South Sweden and characterized using NMRspectroscopy as cis- and trans-dehydroicetexane. Both have a 9(10?20)-abeo-abietane or icetexane skeleton, consisting of a 6-7-6 tricyclic framework with seven carbons in ring B instead of the usual six in common diterpanes of the abietane-type. Dehydroicetexanes can be detected using GC-MS-MS in m/z 270?146 chromatograms without interference from dehydroabietane or other isomers. Dehydroicetexanes are often abundant ...Hans Peter Nytoft, Geir Kildahl-Andersen, Sofie Lindström, Frode Rise, Achim Bechtel, Danica Mitrović, Nataša Đoković, Dragana Životić, Ksenija A. Stojanović.

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.
