Remedijacija otpadnih voda Rudnika prirodnim zeolitom
Igor Veličković (2024)U radu je razmatrano prečišćavanje otpadnih flotacijskih voda sa područja rudnika Rudnik prirodnim zeolitskim tufom sa planine Jastrebac. Prečišćavanje otpadnih flotacijskih voda sa područja rudnika Rudnik prirodnim zeoliskim tufom sa obronaka planine Jastrebac pokazala se veoma efikasnom. Naime, u tri otpadne flotacijske vode utvrđen je povišen sadržaj arsena, hroma, gvožđa, mangana, kao i nikla. Jednostavnim tretmanom zeolitskim tufom iz ovih voda uklonjeni su svi ovi elementi. Sadržaji gvožđe i mangana su sniženi od 95 do 99 %, dok su ...... kozmetici, zaštiti voda, poljoprivredi i sanacijama. S obzirom da je potreba za prirodnim zeolitom u Srbiji oko 7.000 t/god, perspektiva ovog regiona je izuzetna. Kvalitet zeolitizovanog tufa se ogleda u visokom sadržaju klinoptilolita, koji doprinosi visokoj tržišnoj ceni mineralnih sirovina ...

Social-Emo.Sr: Emotional Multi-Label Categorization of Conversational Messages from Social Networks X and Reddit
U digitalnom okruženju južnoslovenskih jezika, analiza emocija u tekstovima na društvenim mrežama postaje sve važnija za razumevanje javnog mnjenja, kreiranje personalizovanog sadržaja i analizu međusobnih interakcija korisnika. U okviru ovog rada predstavljamo detaljnu metodologiju i rezultate označavanja korpusa na srpskom jeziku prema Plutčikovom modelu kategorizacije, koji prepoznaje osam osnovnih emocionalnih kategorija, kao što su radost, tuga, bes, strah, poverenje, gađenje, iščekivanje i iznenađenje.

The oil industry and climate changes
Dejan Radivojević (2020)Uprkos tome što je problem klimatskih promena poznat dugi niz godina i dalje veliki broj ljudi poistovećuje pojam vremenskih prilika sa klimom ne uzimajući u obzir različitu dužinu njihovog trajanja. U medijima se vrlo često mogu naći katastrofična predviđanja vezana za zagrevanje naše planete usled neodgovornog ponašanja čoveka.

Testing the energy value of different types of coal by the method of active thermography
In this paper, coal thermograms are presented and analyzed in order to determine their energy value. Two types of coal of different categories, brown and lignite, were selected for active thermographic imaging. The tested coal samples were processed before measurement so that they are similar in dimensions and have two plane-parallel smooth surfaces. The test samples were "primarily" heated under the same conditions and the process of their cooling was monitored by a thermal camera. "Then" they were cooled ...Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Predrag Jovančić, Dragutin Jovković.
