A contribution to the understanding of hydrochemical properties of thermomineral water on the L’dži locality (eastern part of North Macedonia)
Hristina Petrova, Katarzyna Wątor, Piotr Rusiniak, Boris Vakanjac, Vesna Ristić Vakanjac, Ewa Kmiecik (2023)Regarding the aspect of mineral, thermo-mineral, and thermal waters, on the territory of the Republic of North Macedonia, there are 65 registered locations, of which 8 are categorized as spas. This includes the Kežovica spa, also known as the Štipska spa. In the vicinity of Kežovica Spa is the thermo-mineral L’Dži spring with mineralization around 1.3 g/L and the water temperature at the time of sampling was 50.1 °C. Spring L’Dži is generated by a fault structure and is ...Hristina Petrova, Katarzyna Wątor, Piotr Rusiniak, Boris Vakanjac, Vesna Ristić Vakanjac, Ewa Kmiecik.

Ecological status of the Lim river alluvium in Serbia
Amel Kurbegović, Boris Vakanjac, Vesna Ristić Vakanjac, Mirjana Bartula, Zorana Naunović, Nikola Milovanović, Jovan Kovačević (2022)Three countries share the catchment of the Lim River and they have been engaged in an eco-logical struggle for years, to conserve the river, its tributaries, and biodiversity. Honoring international conventions and declarations, along with active involvement of the civil society and support of Eu-ropean Union agencies, major efforts are being made to draw attention to the degradation of nature, especially water, which is essential for life on the planet Earth. Considering that natural resources are limited and that ...Amel Kurbegović, Boris Vakanjac, Vesna Ristić Vakanjac, Mirjana Bartula, Zorana Naunović, Nikola Milovanović, Jovan Kovačević.

Konzervacija miocenskih kičmenjaka sa lokaliteta Riđake (severozapadna Srbija) iz zbirke Prirodnjačkog muzeja u Beogradu
Nenad Mladenović (2024)U radu je opisana geološka građa terena i metode koje se koriste u paleontologiji za izdvajanje, konzervaciju i restauraciju fosilnog materijala sa lokaliteta Riđake kod Šapca. Prikazana je anatomija fosilnih kičmenjaka. U prosejanom sedimentnom materijalu težine od 4kg pronađeno je 10,798 kostiju, uključujući ostatke Pisces (riba) Amphibia (vodozemaca), Reptilia (gmizavaca), Aves (ptica) i Mammalia (sisara).... direktno ulivaju u Savu ili pripadaju slivovima Jadra, Tamnave ı Kolubare, čine ovu oblast veoma razuđenom. Sliv reke Jadar Je najbogatiji vodom, manju količinu vode imaju pritoke Save i Tamnave, koje u letnjim mesecima uglavnom presušuju (Filipović i dr. 1967). U oblastima gde se pojavljuju stene ...
... otapanja koristi princip širenja vode prilikom prelaska u čvrsto stanje (led) kako bi se oslobodili fosili iz mekih glinovito-laporovitih stena (slika 5). Ova metoda uključuje istiskivanje vazduha iz pora stene u vakuum-komori, nakon čega se stena naglo potapa u vodu i izlaže mrazu, što dovodi do ...
... sumporne kiseline. Postupak uključuje potapanje stene sa fosilom u mlak rastvor šećera (375 grama šećera na 1 litar vode) na period od dve do tri nedelje, uz dopunjavanje isparene vode. Nakon tog vremena, stena se vadi i potapa u koncentrovanu sumpornu kiselinu koja se kuva 15-20 minuta radi jače ...Nenad Mladenović.

The influence of alkyl polyglucosides (and highly ethoxylated alcohol boosters) on the phase behavior of a water/toluene/technical alkyl polyethoxylate microemulsion system
Marija Ilic, Franz-Hubert Haegel, Vesna Pavelkic, Dragan Zlatanovic, Snezana Nikolic-Mandic, Aleksandar Lolic, Zoran Nedic (2016)The influence of additives (alkyl polyglucoside, Glucopon 600 CS UP and alcohol ethoxylate C18E100) on the behavior of the water/toluene/Lutensol ON 50 (technical oxoalcohol, i-C10E5) microemulsion system as a function of temperature and composition has been investigated. The phase behavior of the microemulsions was determined by vertical sections through the Gibbs phase prism (fish-like phase diagrams). Alkyl polyglucoside shifts the one phase region to lower temperatures compared with water/toluene/Lutensol ON 50 mixtures. This is contrary to the expectation, considering ...микроемулзија, толуен, алкил полиглукозид, оксоалкохол етоксилат, појачивач ефикасности, „fish“ дијаграми... onog sistema voda/foluol/lutenso!
