AB  - This investigation was aimed to develop films and coatings based on natural biopolymers and active components, with physicochemical and functional properties for application in antimicrobial packaging. Biopolymer films were obtained from emulsions and dispersions by casting method. Coatings were formed by the application of emulsions on existing packaging. Synthesis of emulsions and dispersions were performed by combining biopolymers (chitosan-gelatin, pectin-gelatin) with lemongrass essential oil (LEO), Zn(CH3COO)2•2H2O, or ZnO, as active components. Fourier transform infrared (FTIR) spectra of the films showed that the addition of glycerol contributed to the forming of strong hydrogen bonds between glycerol and chitosan-gelatin or pectin-gelatin composites, facilitating the process of polymer branching, which is substantial for encapsulation. Thermal analyses revealed two characteristic processes occurring at 110 °C (water evaporation) and within 215–235 °C (degradation of polysaccharide and glycerol). Major weight losses were observed at 290 °C (chitosan-gelatin films) and 215 °C (pectin-gelatin films). The chitosan-gelatin films exhibited a lower degree of solubility (31–21%), and better mechanical properties comparing with the pectin-gelatin films. The chitosan-gelatin emulsions and dispersions exhibited a higher antibacterial effect in vitro against E. coli, B. subtilis, and S. aureus. In the case of the pectin-gelatin emulsions, the impact of LEO on the antibacterial activity was evident. The effects of biopolymer coatings on the development of microorganisms on fresh raspberries (Rubus idaeus L.) were performed in vivo during eight days of raspberry storage at refrigerator temperature. The tested coatings extended the shelf life of stored raspberries from four to eight days. The synergistic effect between LEO and ZnO or Zn-Ac was observed both in vivo and in vitro.

AB  - In the research phase of the geological status of the area of southeastern Banat, samples were collected from surface waters, wells, and lakes. The content of U, Ra, Rn is determined in water. The sampling network was adjusted to the hydrographic characteristics of the terrain, and a hydrogeochemical map has been made at a scale of 1:50 000. In addition to hydrogeochemical prospecting, samples of the soil river sediments were taken to determine the profile of the coast of the following lakes: Vračarevo, Šaransko, Bagersko and Veliko lake. The regional hydrogeochemical prospecting included the area of the Bela Crkva, which drained the sediments of Negotin and Kvartara. In this area and wider, in accordance with the results of regional investigation, semi-geological and semi-geochemical research was carried out to identify resources of mineral deposits as well as the sources for water supply of rural settlements. During research, samples of water from surface streams, sources, wells, lakes, water reservoirs, creek sediments and wall samples were collected and examined.
AB  - U fazi istraživanja geološkog statusa područja jugoistočnog Banata, prikupljeni su uzorci sa površinskih akvatorija, bunara i jezera. U vodi je determinisan sadržaj U, Ra, Rn. Mreža uzorkovanja je prilagođena hidrografskim karakteristikama terena, i napravljena je hidrogeohemijska mapa 1:50 000. Pored hidrogeohemijske prospekcije, uzeti su uzorci rečnih sedimenata zemljišta kako bi se odredio profil obale sledećih jezera: Vračarevo, Šaransko, Bagersko i Veliko jezero. Regionalna hidrogeohemijska prospekcija obuhvatila je područje Bele Crkve, koje dreniraju sedimente Neogena i Kvartara. U ovom području i šire, u skladu sa rezultatima regionalnih ispitivanja, obavljena su i poludetaljna geološka-geohemijska istraživanja u cilju identifikacije ležišta mineralnih sirovina, kao i izvorišta za vodosnabdevanje ruralnih naselja. U toku prospekcije, prikupljeni i ispitani su uzorci voda iz površinskih tokova, izvora, bunara, jezera, vodenih akumulacija, potočnih sedimenata i uzorci stena.
