Hidrogeoekološki uslovi eksploatacije kamenih i mrkih ugljeva Srbije
Branko R. Miladinović (2016-04-27)Ugalj predstavlja energent na čijoj osnovi se razvija privreda celog sveta.Zato mu se pridaje velika pažnja u eksploataciji i preradi, bez obzira na mnogeštetne uticaje na životnu sredinu, a posebno na efekat staklene bašte koji sestvara emisijom zagađujućih materija u atmosferu radom termoelektrana naugalj.U Srbiji, resurs koji se danas u najvećoj meri koristi u proizvodnjielektrične energije je ugalj i on učestvuje u proseku sa 70 %. U strukturi ukupneproizvodnje ugljeva, dominiraju lignitski ugljevi sa učešćem od 98 %, a ...Srbija, kameni i mrki ugalj, podzemna eksploatacija, preradauglja, rudničke vode, hemijski sastav, emisija zagađujućih materija, životnasredina... lI la A V lH O B V In V 1 3 ja B J b y je M A a je u r r a v n a n a a e p s z ja M o r A O K T o p C K o r p a n a V lC T O B e T H a e n e k r p o a c x c ] B e p 3 V 1 jV l x o jy c a M n p e a a o /n a a a o 6 ja B J b V lB a l- b e H a n o p r a n y ,QlilrlilTaI1HOr penoaaropajyva YHIiIBep31i1TeTa ...

Determining the Groundwater Balance and Radius of Influence Using Hydrodynamic Modeling: the Case Study of the Groundwater Source “Šumice” (Kikinda, Serbia)
A groundwater flow model was developed to simulate groundwater extraction from the public water supply source of the City of Kikinda. The hydrodynamic model includes the municipal groundwater source of Kikinda (Šumice and the Jezero Well), but also an extended area where there are groundwater sources that provide water supply to three factories: (MSK, TM and LŽT - Kikinda). Hydrodynamic modeling, based on the numerical method of finite differences will show the groundwater balance of the sources in the ......

Overcoming the Low Oral Bioavailability of Deuterated Pyrazoloquinolinone Ligand DK-I-60-3 by Nanonization: A Knowledge-Based Approach
Jelena R. Mitrović , Branka Divović-Matović, Daniel E. Knutson, Jelena B. Ðoković, Aleksandar Kremenović, Vladimir D. Dobričić, Danijela V. Randjelović, Ivana Pantelić, James M. Cook, Miroslav M. Savić, Snežana D. Savić (2021)Poor water solubility of new chemical entities is considered as one of the main obstacles in drug development, as it usually leads to low bioavailability after administration. To overcome these problems, the selection of the appropriate formulation technology needs to be based on the physicochemical properties of the drug and introduced in the early stages of drug research. One example of the new potential drug substance with poor solubility is DK-I-60-3, deuterated pyrazoloquinolinone, designed for the treatment of various neuropsychiatric ......

Fuzzy Model for Risk Assessment of Machinery Failures
The main goal of this research was the development of an algorithm for the implementation of negative risk parameters in a synthesis model for a risk level assessment for a specific machine used in the mining industry. Fuzzy sets and fuzzy logic theory, in combination with statistical methods, were applied to analyze the time picture state of the observed machine. Fuzzy logic is presented through fuzzy proposition and a fuzzy composition module. Using these tools, the symmetric position of the ......

Kvantitativna ocena režima i bilansa podzemnih voda u aluvijonu Velike Morave od Bagrdana do ušća u Dunavu
Aleksandar Balubdžić (2024)Aluvijalni sedimenti velikih reka raspolažu značajnim količinama podzemnih voda, što je zajedno sa površinskim vodama dozvolilo razvoj naselja i ljudskih aktivnosti. Ovaj razvoj uslovljava veće potrebe za vodnim resursima i njihovim kvalitetom. Sa povećanjem eksploatacije podzemnih voda, uticaj iste je značajniji i može da dovede do opadanja nivoa podzemnih voda i pogoršanja kvaliteta. Aluvijon Velike Morave ima značajno rasprostranjenje, usled čega predstavlja važno ležište izdanskih voda sa velikim eksploatacionim mogućnostima.

Freeze-dried nanocrystal dispersion of novel deuterated pyrazoloquinolinone ligand (DK-I-56-1): Process parameters and lyoprotectant selection through the stability study

Cook, Miroslav M. Savić, Snežana D. Savić (2023)Recently, nanocrystal dispersions have been considered as a promising formulation strategy to improve the bioavailability of the deuterated pyrazoloquinolinone ligand DK-I-56-1 (7‑methoxy-2-(4‑methoxy-d3-phenyl)-2,5-dihydro-3H-pyrazolo[4,3-c]quinolin-3-one). In the current study, the freeze-drying process (formulation and process parameters) was investigated to improve the storage stability of the previously developed formulation. Different combinations of lyoprotectant (sucrose or trehalose) and bulking agent (mannitol) were varied while formulations were freeze-dried under two conditions (primary drying at -10 or -45 °C). The obtained lyophilizates were characterized in terms ...... dispersion of novel deuterated pyrazoloquinolinone ligand (DK-I-56-1): Process parameters and lyoprotectant selection through the stability study Jelena R.

Synthesis and characterization of high-pressure and high-temperature sphene (CaTiSiO5)
Jelena Pantić, Vladimir Urbanovich, Vesna Poharc-Logar, Bojan Jokić, Marija Stojmenović, Aleksandar Kremenović, Branko Matović (2014)Sphene (CaTiSiO5), a calcium titanosilicate ceramic has been prepared from a powder mixture of CaCO3, TiO2 and SiO2 using vibro-milling for homogenization and activation of precursors. During the highpressure and high-temperature synthesis (HPS) process at 4 GPa and 1,200 °C, sphene undergoes into phase transition, from room-temperature phase P21/a to high-temperature phase A2/a. Evidence of that structural phase transition is given in this paper using infrared, Raman spectroscopy and X-ray powder diffraction. Rietveld refinement was employed to get the ...Jelena Pantić, Vladimir Urbanovich, Vesna Poharc-Logar, Bojan Jokić, Marija Stojmenović, Aleksandar Kremenović, Branko Matović.
