Dragana D. Đurić (2019)U radu je prvi put opisan deo herpetofaune (Anura i Squamata) iz neogenih i kvartarnih lokaliteta Srbije. Obrađeni su lokaliteti Sibnica, Prebreza, Lazarevc, Vračević i Riđake, neogene starosti. Lokaliteti kvartarne starosti su pećine Mala i Velika Balanica, Pešturina, Hadži Prodanova, Baranica, Vrelska pećina i sedimentne ispune fisura u kamenolomima Venčac i Beočin. U radu je prikazana je taksonomska analiza herpetoloških ostataka. Pored taksonomske analize fosilnog materijala dat je kratak geografsko-geološki opis proučavanih lokaliteta, osnovne osteološke karakteristike anura i skvamata ......

Одређивање оптималне производње дубинске пумпе на клипним шипкама
Небојша Савић (2024)Дужи временски период током историје производње нафте, дубинске пумпе на клипним шипкама су први и у многим случајевима једини избор када су у питању механичке методе експлоатације. Правилан одабир сваког појединачног елемента система омогућава оптимизацију која са собом повлачи бенефите у виду повећавања ефикасности и смањења трошкова. Тренутно примењени систем дубинских пумпи на клипним шипкама на лежишту „Н“ обезбеђује стабилну производњу и реализацију годишњих планова производње без већих проблема. У овом раду је приказан начин оптимизације производње дубинским пумпама ...... I k Epoj Hnekca /PS 23 / yA HsjaBMbyjeM a je 3aBpIHHH pa/jl TiOJi HaCJIOBOM ONA A — _ 204> !

Synthesis, magnetic, thermal and structural properties of Co(II), Ni(II) and Cu(II) complexes containing isophthalato ligands
A series of novel ternary Co(II), Ni(II) and Cu(II) complexes containing 2,20-dipyridylamine (dipya), 2,20-bipyridine (bipy), and 1,10-phenanthroline (phen), as aromatic diamine ligands, and dianion of isophthalic acid (ipht) have been prepared by ligand exchange reactions from diluted H2O/EtOH solutions. The complexes were characterized by elemental analysis, IR spectroscopy, magnetic susceptibility measurements and TG and DSC analysis. Three complexes, Cu(dipya)(ipht)H2O (1), Co(dipya)(ipht)2H2O (2) and Cu(ipht)(phen)2H2O (5) are polymeric with bis-monodentate ipht, while the other two complexes M(bipy)(ipht)4H2O, M@Co(II) (3) and ...комплекси прелазних метала, карбоксилатни лиганди, N-лиганди, кристална структура, магнетна својстваJelena Rogan, Dejan Poleti, Ljiljana Karanović, Zvonko Jagličić.

Laboratory testing of fly ash
Fly ash is one of the most common waste materials created by burning of coal. It is composed of smaller particles, consisting mainly of aluminosilicate glass, mullite and quartz, which are collected by electrostatic separators (filter) of gaseous products arising from the combustion of coal.
