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.

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.

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.

The influence of Al<sup>3+</sup>ion on porcine pepsin activity<i>in vitro</i>
The in vitro effect of Al3þ ions in the concentration range 1.7·1026M–8.7·1023M on pepsin activity at pH 2, via kinetic parameters and its electrophoretic mobility was evaluated. Kinetic study demonstrated the existence of an activation effect of Al3þ at pH 2 on pepsin molecule. Kinetic analysis with respect to concentrations of haemoglobin showed that Al3þ ions increase the maximal velocity (Vmax) and kcat values rather than apparent affinity for substrate (KS) implying the non-competitive nature of activation which indicated ...... values in the presence of activator from that in its absence, are linear [29,30].

Antioxidant and antimicrobial activity of some tetradentate Schiff bases and their Cu (II) complexes
Aleksandar Mijatović, Milan Nikolić, Snežana Spasić, Aleksandra N. Žerađanin, Kristina Joksimović, Aleksandar Lolić, Rada Baošić (2020)Šifove baze i njihovi Cu(II) kompleksi su poznati po svojoj biološkoj aktivnosti. U ovom radu proučavana je antibakterijska aktivnost protiv gram-negativnih sojeva Escherichia coli, Pseudomonas aeruginosa i Staphilococcus piogenes, kao i Gram-pozitivnih Staphilococcus piogenes i Pseudomonas aeruginosa, zajedno sa antifungalnim dejstvom protiv Musperg strainilusa, A. Takođe, tehnički jednostavni i brzi testovi kao što su ABTS, HORAC i ORAC korišćeni su za ispitivanje antioksidativne aktivnosti kako bi se uporedili dobijeni rezultati sa različitim tipovima testova. Uprkos tome što je princip ...Aleksandar Mijatović, Milan Nikolić, Snežana Spasić, Aleksandra N. Žerađanin, Kristina Joksimović, Aleksandar Lolić, Rada Baošić.

Three new Sr-bearing arsenates, hydrothermally synthesized in the system SrO–MO–As2O5–H2O (M2+ = Mg, Cu, Zn)
Tamara Đorđević, Ljiljana Karanović (2018)During systematic research on the mineral-related synthetic arsenates, with particular focus on their structural and spectroscopic classification, three new Sr-containing arsenates Sr2Mg(AsO4)2· 2H2O (1), Sr2Zn4(AsO4)4·H2O (2) and Sr2Cu7(AsO4)6 (3) have been synthesized under low-temperature hydrothermal conditions in the system SrO MO As2O5 H2O (M 2þ = Mg, Zn, Cu). Their crystal structures were determined using room-temperature single-crystal X-ray diffraction data and refined to the following R-values: 1– R1 = 0.025; 2– R1 = 0.030; 3– R1 = 0.035.
