Mineralni i hemijski sastav čestica u atmosferi zone Kolubarskog basena i uticaj na životnu sredinu
Željko R. Cvetković (2013-11-18)Čestice iz vazduha su prikupljane u blizini termoelektrane i površinskih kopovarudnika uglja u Kolubarskom basenu. Izmereni srednji sadržaji koncentracija rastvornih,nerastvornih i ukupnih taložnih materija na godišnjem nivou prelaze 200 mg/m2dan (K-1, K-3, K-4, K-5).

Classification of Terms on a Positive-Negative Feelings Polarity Scale Based on Emoticons
Mihailo Škorić (2017)The goal of this paper is to draw attention to the possibility of using emoticon-riddled text on the web in language-neutral sentiment analysis. It introduces several innovations in the existing framework of research and tests their effectiveness. It also presents a software tool especially made for that purpose, explains how it builds a database with sentimental value of terms and offers the user manual. Finally, it presents a software tool that tests the new database and gives some examples ...... mapped from set (0, 10) onto set (−1, 1), which was done by applying the formula: x = (x− 5)/5 (1) Thus, the value of which corresponds to a negative mood of highest intensity became −1, while the value corresponding to the highest intensity of the positive mood became 1. Also a universal correction factor ...

Geotehnički uslovi izgradnje tunela „Debelo brdo“ na autoputu E-80 Niš - Pločnik
Tunel „Debelo brdo“ nazvan je po najizraženijem relјefnom obliku na ovoj drugoj deonici autoputa E-80 Niš – Pločnik. Osnovnu geološku građu na lokaciji tunela čini Mio-Plioceni kompleks heterogenog litološkog sastava. Izgradnja tunela je predviđena delom u otvorenom iskopu dužine 240 m, a delom sa podzemnim iskopom dužine 190 m. U zoni tunela, padina je okarakterisana kao uslovno stabilna, pa bi neadekvatna zasecanja mogla da izazovu klizanja terena. Iz tih razloga, u okviru rada posebno su prikazani geotehnički uslovi izgradnje ...... s. - The Repository is available at: www.dr.rgf.bg.ac.rs PROCEEDINGS PROCEEDINGS Dragoslav Radojica , Irena 36 AUTOPUTU E- - 1, 2 3 4 1 Univerzitet u Beogradu Rudarsko- a 7, Beograd, dragoslav.rakic@rgf.bg.ac.rs 2 Univerzitet u Beogradu Rudarsko- a 7, Beograd, radojica.lapcevic@rgf ...

Structural dissymmetrization of optically anisotropic Grs64±1Adr36±1Sps2 grandite from Meka Presedla (Kopaonik Mt., Serbia)
In this paper, grandite core with Grs64±1Adr36±1Sps2composition was crystallographically studied. This core represents zone A of the macroscopically visiblefive A–E zones of the optically anisotropic Grs58–64 Adr36–42Sps2 grandite. The applied procedure includes the detailed analysis of the powder diffraction patterns, and the Rietveld refinements of the crystal structures in a series of 18 space groups and two mixtures, which were followed by the comparative analysis of the R-values, site occupancy factors, and the bond lengths and angles.
