Приказ коморно-стубне методе откопавања са подетажним откопавањем стубова и накнадним засипавањем откопа
Милош Вуковић (2024)Коморно-стубна метода откопавања са подетажним откопавањем стубова се користи за рудне жиле и сочива, стрмог пада.У овом раду су приказани основни елементи примењене методе откопавања као што су: димензионисање просторија припреме, бушачко-минерски радови,утовар и транспорт,вентилација и запуњавање откопаног простора паста засипом. Анализом трошкова прорачуната је цена израде припремних просторија, по дужном метру, на основу квалитета радне средине у којима се израђују. Такође, анализирани су трошкови при експлоатацији руде и приказани су јединичном вредношћу USD/t (долара по тони руде).На крају ...... xnacu, Si=15,17 m?, f=8 Pen. IleHa Bpcra rTpontkoBa Bp.

Curcumin nanonization using an alternative small-scale production unit: selection of proper stabilizer applying basic physicochemical consideration and biological activity assessment of nanocrystals
Ines Nikolić, Jelena Antić-Stanković, Dragana Božić, Danijela Ranđelović, Bojan Marković, Dominique Jasmin Lunter, Aleksandar Kremenović, Miroslav Savić, Snežana Savić (2020)As the number of poorly soluble drugs is increasing, nanocrystals have become very interesting due to wide range of application possibilities. Curcumin was used as a model active ingredient in this work. Even though it has many proven positive effects, due to its physicochemical issues, its possibilities have not been fully exploited. The goal of this work was to select optimal conditions for a top-down method for curcumin nanosuspension production, and to perform their comprehensive characterization applying complementary methodologies: ...Ines Nikolić, Jelena Antić-Stanković, Dragana Božić, Danijela Ranđelović, Bojan Marković, Dominique Jasmin Lunter, Aleksandar Kremenović, Miroslav Savić, Snežana Savić.

Clockwise vertical-axis rotation in the West Vardar zone of Serbia: Tectonic implications
The Vardar-Tethyan mega-suture between the Eurasian and Adria (Gondwana) margins comprises remnants of oceanic lithosphere of Neotethys and distal parts of the adjacent continental margins including unconformable Late Cretaceous sedimentary cover and Cenozoic igneous rocks of post-obduction age. This study provides kinematic constraints for displacements and rotations affecting the Serbian part of the West Vardar and Jadar-Kopaonik units after the closure of the Neotethyan (= Sava) Ocean. The targets of the paleomagnetic research were Late Cretaceous sediments representing an ......

Frequency and Length of Syllables in Serbian
Marija Radojičić, Biljana Lazić, Sebastijan Kaplar, Ranka Stanković, Ivan Obradović, Ján Mačutek, Lívia Leššová (2019)Basic analyses of several properties of syllables (the rank-frequency distribution, the distribution of length, and the relation between length and frequency) in Serbian is presented. The syllabification algorithm used combines the maximum onset principle and the sonority hierarchy. Results indicate that syllables behave similarly to words as far as mathematical models are concerned, but values of parameters in models for syllables are quite different from those for words.... phonemes in Serbian language vowels a(а), e(е), i(и), o(о), u(у) consonants sonorants j(ј), l(л), lj(љ), m(м), n(н), nj(њ), r(р), v(в) obstruents b(б), c(ц), č(ч), ć(ћ), d(д), dž(џ), đ(ђ), f(ф), g(г), h(х), k(к), p(п), s(с), š(ш), t(т), z(з), ž(ж) Two further aspects of Serbian must be taken ...
