Coal homogenization stockyard sizing “Tamnava – Zapad” case study
... cases the length, width and height of the stacked coal are sized. In these considerations the problem of self-inflaming of coal, availability of space, availability of funding, etc., are not taken into account. Only the technical and technological parameters affecting the size of the pile and stockyard ...
... 000 t 180,000 t Thus, statistically speaking, a larger quantity of coal can be stored in the same area if there are fewer piles, because less space is left between piles. The homogenization stacking system always starts so that at least one pile is completely filled, while another is being emptied ...Božo Kolonja, Dinko Knežević, Ranka Stanković, Dejan Stevanović, Detlef Trummer.

Анализа могућности примене метода повећања степена искоришћења на нафтном лежишту "Ј"
Иван Савић (2024)Комплексно лежиште „Ј“ је сачињено од колектор стена различите стратиграфске припадности и хетерогеног литолошког састава. Лежиште се налази у последњој фази разраде, а током животног века експлоатисано је само примарним методама. У раду је приказана анализа стања разраде лежишта, а као основни фактори који су допринели ниском степену искоришћења лежишта издвојени су вискозност нафте, хетерогеност колектора и пад лежишног притиска. Изведена је хидродинамичка симулациона студија помоћу које је издвојена најпогоднија зона за пилотну примену терцијарних метода. Коришћењем „скрининг“ критеријума ......

Phase relations and physical indicators of municipal waste from old landfills in Serbia
Due to certain similarities of municipal waste and soil, usually for the determination of basic parameters of physical state, laboratory and field tests which are common in geotechnical investigations are used. It is often to construct an apparatus for special purpose to perform some specific laboratory and field tests. Therefore, different values of indicators of municipal waste physical state can be found in the literature. The basic reasons should be found in different definitions and methods that researchers use ...municipal waste, moisture content, unit weight, specific gravity, grain size distribution, porosityGeneral Computer Science... materials at higher temperatures). Municipal waste moisture content can be observed based on the mechanism of fluid retention within the pore space of waste: a) moisture within waste particles 1.e. moisture in pores inside particles, b) moisture between particles 1.c. in pores between particles ...

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 ...... are used for industrial purposes. Although the use of coal, especially in the countries of the European Union, is in constant decline, there is space for additional reduction. Through this paper, the authors wanted to present the completely actual situation of emissions of CO» from thermal power ...Uroš Djorgovski, Aleksandar Madžarević, Predrag Jovančić.

An Approach to Efficient Processing of Multi-Word Units
Efficient processing of Multi-Word Units in the course of development of morphological MWU dictionaries is not easy to achieve, especially when languages with complex morphological structures are concerned, such as Serbian. Manual development of this type of dictionaries is a tedious and extremely slow process. To alleviate this problem we turned to our multipurpose software tool, dubbed LeXimir, in the production of lemmas for e-dictionaries of multi-word units. In addition to that, we developed a procedure aimed at making ...... become values of variables: in the case of petokraka zvezda values of variables become $1=petokraka, $2=<space>, $3=zvezda while in the case of Farenhajtov stepen they are $1=Farenhajtov, $2=<space>, $3=ste- pen.

Sinteza i karakterizacija vanadata alkalnih metala sa elementima retkih zemalja
Anđela Jovanović (2024)Predmet i cilj pisanja ovog rada su sinteza i karakterizacija vanadata alkalnih metala sa elementima retkih zemalja. Prilikom ovih istraživanja, ispitivan je sistem REE2O3–V2O5–KF, gde REE predstavlja trovalentni katjon izabranih elemenata retkih zemalja (Y, Sm, Eu, Gd, Er, Yb). Ovo istraživanje bazirano je na sintezi kristala, nakon čega su dobijeni kristali posmatrani pod binokularnom lupom, analizirani metodom rendgenske difrakcije na polikristalnom materijalu (XRPD) i metodom skenirajuće elektronske mikroskopije sa energetsko-disperzivnom spektroskopijom (SEM-EDS), kako bi se utvrdile karakteristike dobijenih kristala. ...elementi retkih zemalja, sinteza kristala metodom fluksa, vanadati alkalnih metala, rendgenska difrakcija, SEM-EDS metodaAnđela Jovanović.
