Sorpcija herbicida na neorganski i organski modifikovanom prirodnom montmorionitu iz Bogovine
Lazar M. Kaluđerović (2018-01-17)fikasnost prilikom sorpcije S-metolahlora i klomazona od strane neorganskih iorganski modifikovanih montmorionita sa lokaliteta Bogovina odreĎena je metodombach adsorpcije. Uzorci montmorionita su tretirani prvo rastvorom NaCl a zatim irazličitim koncentracijama organskih kompleksa. Adsorpcione izoterme su dobijenetretiranjem uzoraka različitim koncentracijama herbicida. Detaljna mineraloškakarakterizacija uzoraka uraĎena je metodom rendgenske difrakcije. Rezultati interakcijemontmorionita sa organskim kompleksima i herbicidima dobijeni su primenomrendgenskih, optičkih, termičkih i spektroskopskih metoda.Na osnovu rezultata rendgenskih ispitivanja uzoraka, utvrĎeno je prisustvoorganskih kompleksa i herbicida u meĎuslojnom prostoru montmorionita.Montmorioniti modifikovani ...adsorpcija, montmorionit, heksadeciltrimetilamonijum bromid,feniltrimetilamonijum hlorid, S-metolahlor, klomazon...

Prioritization of strategic measures for strengthening the security of supply of the Serbian natural gas sector
To strengthen the security of supply of the Serbian gas sector, it is necessary to analyze the impact of planned strategic measures. The analysis involves the identification of the most influential threats to the security of natural gas supply and prioritization of the strategic measures for overcoming the consequences of threats. The proposed methodology is based on Fuzzy Analytic Hierarchy Process. The obtained weights for the identified threats and strategic measures are formed according to experts' judgments.

Photocatalytic Activity of the V2O5 Catalyst toward Selected Pharmaceuticals and Their Mixture: Influence of the Molecular Structure on the Efficiency of the Process

Savanović, Nataša Tomić, Aleksandar Kremenović, Maja Šćepanović, Mirjana Grujić-Brojčin, Jovana Ćirković, Stevan Armaković (2023)Due to the inability of conventional wastewater treatment procedures to remove organic pharmaceutical pollutants, active pharmaceutical components remain in wastewater and even reach tap water. In terms of pharmaceutical pollutants, the scientific community focuses on -blockers due to their extensive (over)usage and moderately high solubility. In this study, the photocatalytic activity of V2O5 was investigated through the degradation of nadolol (NAD), pindolol (PIN), metoprolol (MET), and their mixture under ultraviolet (UV) irradiation in water.

Self-Engineering: Possibilities for Maintenance Operations in the Mining Machines Industry
Self-engineering is a relatively new branch of knowledge that aims to understand how systems could “autonomously” re-configure or repair themselves without the intervention of the operators. A direct field of application is within the maintenance spectrum. Having systems or machines capable of self-detecting or even self-repairing could represent a game-changer, in capital asset fields such as the mining industry in particular. This paper aims to investigate the possible benefits and challenges of self-engineering / self-maintenance concerning mining machines, specifically bucket-wheel ...self-engineering, self-maintenance, maintenance operations, mining industry, bucket-wheel excavator, gearbox revitalizationSteven Manders, Milorad Pantelić, Vladimir Milisavljević, Alberto Martinetti.

Production of morphological dictionaries of multi-word units using a multipurpose tool
The development of a comprehensive morphological dictionary of multi-word units for Serbian is a very demanding task, due to the complexity of Serbian morphology. Manual production of such a dictionary proved to be extremely time-consuming. In this paper we present a procedure that automatically produces dictionary lemmas for a given list of multi-word units. To accomplish this task the procedure relies on data in e-dictionaries of Serbian simple words, which are already well developed.

The application of ArcGIS for assessing the potential of solar energy in urban area: The case of Vranje
In order to determine the solar energy potential for a specified location, it is crucial to consider the latitude, altitude, slope, terrain morphology, atmospheric conditions, etc. Such a complex calculation and mapping of solar energy can be done using the ArcGIS geoprocessing tool, named Area Solar Radiation (ASR). By using the ASR tool, supported with the adequate input data, it is possible to calculate the maximum solar radiation energy (irradiation) for a defined area and for a specified time ...... ution satellite imagery (Copernicus land Monitoring Service, 2019a).
