A hundred years of Milutin Milanković's climate change theory - geological implications
Dejan Radivojević (2020)Миланковићева теорија циклуса објављена пре сто година је најважнија теорија у наукама које проучавају климу и имала је велики утицај на дисциплине које се баве Земљом. Ипак, његов рад је чекао више од педесет година да би добио потврду. Може се рећи да Миланковићев рад највећи утицај на геологију има у изради астрономске временске скале, подршци хипотези континенталног дрифта и палеоклиматологији. Добри резултати примене астрономске временске скале на неогене седименте иницирали су примену ове методе у мезозојским и у последње ...циклостратиграфија, астономска временска скала, геолошка временска скала, климатске промене, континентални дрифт... mum, Walvis Ridge (oDP Sites 1262, 1263, and 1266): Evidence from Mn and U enrichment factors.

Design of a sucker rod pumping system
Ana Ponoćko (2024)For a long time in the history of oil production, sucker rod pumps have been the first and in many cases the only choice when it comes to mechanical extraction methods. Proper selection of each individual element of the system enables optimization, which entails benefits in the form of increased efficiency and reduced costs.

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 ...... l.

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.

Adaptive neuro-fuzzy prediction of operation of the bucket wheel drive based on wear of cutting elements
The capacity of the rotor excavator depends largely on the operation of the subsystem for digging. There is a great contribution to the correct and sharp teeth when the capacity is the highest. In the function of time, the teeth become clogged due to abrasive wear, or changes in their geometric shape. To analyze the bucket wheel drive in depend on wear of the cutting elements in this study adaptive neuro fuzzy inference system (ANFIS) approach was implemented. ANFIS ...Filip Miletić, Predrag D.

Smanjenje sleganja plitkih temelja primenom mikrošipova
Slobodan Ćorić, Dragoslav Rakić (2021)Mikrošipovi su šipovi malog prečnika koji se grade tako što se u tlu specijalni postupkom formira bušotina koja se zatim armira i injektira. Njihov prečnik je najčešće 150 – 300 mm, a dužina može da bude i više desetina metara. Mikrošipovi mogu da se grade u svim vrstama tla i mogu da budu vertikalni i kosi. Oni se, stoga, koriste kao zamena za konvencionalne šipove i ankere.

Terminology Acquisition and Description Using Lexical Resources and Local Grammars
Acquisition of new terminology from specific domains and its adequate description within terminological dictionaries is a complex task, especially for languages that are morphologically complex such as Serbian.

Production of electricity from coal-fired power plants and accompanying CO2 emissions: comparison of EU-27 and US
Even in the third decade of the 21st century, large power plants are still responsible for more than half of the electricity production in Europe and US. They predominantly use fossil fuels in their work, which results in the emission of pollutants into the air, soil and water. In addition to the production of electric energy, fossil fuels, including coal, are used for industrial purposes. Although the use of coal, especially in the countries of the European Union, is ...... 14000 j US average: 13061 kWh/c 12000 j 10000 j 8000 j EU-27 average: 6492 kWh/c 6000 4000 j 2000 j ——LFU-27 <——=US 0 eo w i e T T n o u 00 miuČ- O T W i m TO O ~ 0 O O a eNeon E:o:u: ' o e i e oč reeo oeezkžjjBNj“”oZo S Wwe e esA Č e!đ e RT NTe ...

Идејно решење заштите површинског копа ,,Дрмно" од вода у периоду од 2030. године до краја експлоатације
Јован Киселчић (2024)Системи одводњавања на површинским коповима као и други технички системи морају успешно извршавати своју функцију и са свим својим елементима издржавати сва предвиђена напрезања,а при томе бити једноставни и економични.Функција система одводњавања је да спречи доток, пре свега, подземних вода у површински коп и да у одређеном времену испумпа задате количине воде.У овом раду приказани системи одводњавања на површинском копу ,,Дрмно" у периоу од 2023.године до краја експлоатације и то систем одводњавања подземних вода и систем одводњавања површинских вода.На ...... 2.5.4. 3anpeMuHuHcka TexxHHa |IIpHpo/iHa BJ1aJKHOCT Cnenuu(juHa TexxuHa|] paHuna Teueba || paHuna rnacHuHocCTH y= 18,3 KN/m?
