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.

Geomagnetna bura kategorije G5 u maju 2024. godine
Magdalena Marčeva (2024)Zemlja poseduje magnetno polje, koje je generisano u njenom spoljašnjem jezgru. Magnetno polje Zemlje je konstantno izloženo dejstvu sunčevog magnetnog polja i zračenja koje se sa Sunca emituje. Naelektrisane čestice koje pristižu sa Sunca stupaju u interakciju sa magnetosferom, što dovodi do različitih geomagnetnih poremećaja.Geomagnetna aktivnost direktno je proporcionalna intenzitetu sunčevog zračenja koje dolazi do Zemlje. Pod uticajem sunčevog korpuskularnog zračenja dolazi do pojave geomagnetnih bura koje su praćene porastom intenziteta magnetnog polja.Količina i jačina dolaznog sunčevog zračenja zavisi ...... Rz.

Kvartarni klastiti iz bušotine kod Aranđelovca (rasadnik Mladost)
Miroslav Radeta (2024)U ovom radu analizirani su kvartarni klastiti iz bušotine kod Aranđelovca IB 18-3, sa ciljem boljeg razumevanja njihovih sedimentoloških i litoloških karakteristika. Kvartarni sedimenti su prilično homogenog/uniformisanog sastava i čine ih finozrni klastiti (dominantno alevroliti) sa određenim procentom peskovite i glinovite frakcije. Oni su iskartirani u samoj povlati i debljina im je 27 m. U podini su gornjokredne karbonatne stene (krečnjaci, laporci, rekristalisali/mermerisani karbonati) i miocenski sediment predstavljeni raznovrsnim varijetetima klastično karbonatnih stena.

Hyperpycnites within the Devonian-Carboniferous flysch of the Carpatho-Balkanides (Kostadinovica, eastern Serbia)
Miloš Radonjić (2020)This study presents new discoveries of vascular plants and the trace fossil Dictyodora liebeana (GEINITZ) from the Devonian–Carboniferous Kučaj-Zvonce flysch of the Carpatho-Balkanides and the implications of this fossil association for its sedimentary setting. The occurrence of the described plant debris in a deep-marine environment indicates the presence of hyperpycnites within the siliciclastic turbidites exposed at the Kostadinovica locality.

Effect of Properties of Working Fluids on the Efficiency of a Low-Temperature Organic Rankine Cycle
Decarbonization of all segments of energy systems, both on the supply and demand side, is one of the main goals of the energy transition. Electricity supply in the future will largely rely on generation from intermittent energy sources: wind and solar. Locally available, non-utilized alternative low-temperature energy sources as hydro-geothermal wells, and abounded oil and gas wells, have the potential to provide continual energy production over the year. Electricity generation from these energy sources is carried out with working ...Marija Živković, Aleksandar Mijatović, Dejan Ivezić, Boban Pavlović.

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 ......

Rangiranja bagera za njihovu revitalizaciju primenom višekriterijumske analize
Obzirom da je na našim površinskim kopovima trenutno u eksploataciji veći broj rotornih bagera sa sličnim tehničkim karakteristikama i približno istom starošću postavlja se pitanje kako rangirati bagere, i kojim redom da se izvrši njihova revitalizacija. Za ocenu stanja i rangiranje ovako velikog broja bagera najpogodnije se pokazalo korišćenje višekriterijumskih metoda sa višeatributnom ocenom, odnosno bodovanje referentnih indikatora stanja bagera na osnovu ekspertske ocene.

Tracking of the temporal dependency of fading of the human footprint temperature contrast
In certain situations, it is extremely important to determine the exact time “someone” entered or crossed the forbidden zone of a military or strategic installation, a red zone of radioactive, chemical, or biological contamination, a bank or similar structure. Standard security measures include ordinary video surveillance using cameras that operate in the visible range of the electromagnetic spectrum, as well commercial thermal imaging cameras [1, 2]. The paper presents the results of experiments that suggest another possible use of ...Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Darko Vasiljević, Danica Pavlović.
