A contribution to the understanding of hydrochemical properties of thermomineral water on the L’dži locality (eastern part of North Macedonia)
Hristina Petrova, Katarzyna Wątor, Piotr Rusiniak, Boris Vakanjac, Vesna Ristić Vakanjac, Ewa Kmiecik (2023)Regarding the aspect of mineral, thermo-mineral, and thermal waters, on the territory of the Republic of North Macedonia, there are 65 registered locations, of which 8 are categorized as spas. This includes the Kežovica spa, also known as the Štipska spa. In the vicinity of Kežovica Spa is the thermo-mineral L’Dži spring with mineralization around 1.3 g/L and the water temperature at the time of sampling was 50.1 °C. Spring L’Dži is generated by a fault structure and is ...Hristina Petrova, Katarzyna Wątor, Piotr Rusiniak, Boris Vakanjac, Vesna Ristić Vakanjac, Ewa Kmiecik.

High-resolution sequence stratigraphy of carbonates - theory and examples
Jelena Stefanović, Dejan Radivojević (2020)Циљ рада је да кроз теоријски аспект и примере примене представи секвенциону стратиграфију високе резолуције карбонатних седимената. У том смислу први део се односи на појам и значење високе резолуције у секвенционој стратиграфији. Од временских и просторних скала које одговарају сеизмичким профилима у последњих двадесет година метода је нашла примену на скалама које одговарају бушотинским подацима или изданцима. Као најпогоднији седименти за овај тип истраживања су се показали карбонати јер су осетљиви на еустатичке промене, а основе секвенционе стратиграфије ......

Geothermal potential, chemical characteristic and utilization of groundwater in Serbia
To collect and unify data about all geothermal resources in Serbia, a database was formed. The database allows us to perceive the geothermal resources of Serbia and their potential for utilization. Based on the data available in the geothermal database, the estimated temperatures of reservoirs, heat power, and geothermal energy utilization were calculated. The database contains 293 geothermal records (springs, boreholes) registered at 160 locations, with groundwater temperatures in the range between 20 and 111 °C. The maximum expected ...Geothermal database, Geothermal resources, Geothermal potential, Hydrochemistry, Hierarchical cluster analysis, SerbiaTanja Petrović Pantić, Katarina Atanasković Samolov, Jana Štrbački, Milan Tomić.

Application of Peleg model on mass transfer kinetics during osmotic dehydratation of pear cubes in sucrose solution
Vesna Pavelkić, Tanja Brdarić, Marija Petrović, Gavrilo Šekularac, Milica Košević, Lato Pezo, Marija Ilić (2015)The applicability of Peleg model was investigated for predicting mass transfer kinetics during the osmotic dehydration (OD) process of pears, at different concentrations (40, 60 and 70%, w/w) and temperatures (20, 35 and 50 °C) of sucrose solution. Increase in sucrose solution concentration resulted in higher water loss (WL) and solid gain (SG) values through the osmotic treatment period. After 360 min of osmotic treatment of pears, WL ranged from 23.71 to 31.68% at 20 °C, from 24.80 to ...Vesna Pavelkić, Tanja Brdarić, Marija Petrović, Gavrilo Šekularac, Milica Košević, Lato Pezo, Marija Ilić.

Određivanje zbijenosti starog komunalnog otpada
Bez obzira na savremene tretmane komunalnog otpada u svetu, u Srbiji je i dalje najčešći vid odlaganja na komunalne deponije, pa zbijanje otpada predstavlja jednu od ključnih faza formiranja deponije. Na ovaj način znatno se smanjuje zapremina otpada, ubrzava proces degradacije i produžava radni vek deponije. Zbog toga su geotehničke karakteristike komunalnog otpada prilikom zbijanja, veoma bitne kako u fazi projektovanja tako i u fazi izgradnje deponije i optimizacije prostora. Tu se pre svega misli na maksimalnu suvu zapreminsku ...Jovana Janković, Dragoslav Rakić, Irena Basarić Ikodinović, Tina Đurić.

Model za optimizaciju graničnog saržaja metala u rudi u funkciji dugoročnog planiranja površinskih kopova
Daniel P. Kržanović (2016-06-14)Optimizacija graničnog sadržaja metala u rudi jedan je od osnovnih koraka u planiranju i dizajniranju površinskih kopova i ima za cilj postizanje maksimalne neto sadašnje vrednosti (NPV). Iz tog razloga, optimizacija graničnog sadržaja i danas je predmet mnogih istraživanja u rudarskoj nauci, sa ciljem rešavanja praktičnih problema u eksploataciji ležišta.Dugoročno planiranje eksploatacije na površinskim kopovima podrazumeva sagledavanje svih relevantih parametara i faktora (geologije rudnog ležišta, tehnologije proizvodnog procesa, kapaciteta otkopavanja i prerade, troškova, cena metala, iskorišćenja i dr) kako ...površinski kop, dugoročno planiranje, optimizacija graničnog sadržaja, maksimizacija neto sadašnje vrednosti (NPV).... oblik: 1 ) Inicijalizacija Izbor početnog rešenja x, xopt=x, fopt=f(x). 2 ) Ponavljanje a) Pokušaj.

Geomagnetna bura kategorije G5 u maju 2024. godine
Magdalena Marčeva (2024)Zemlja poseduje magnetno polje, koje je generisano u njenom spoljašnjem jezgru. Magnetno polje Zemlje je konstantno izloženo dejstvu sunčevog magnetnog polja i zračenja koje se sa Sunca emituje. Naelektrisane čestice koje pristižu sa Sunca stupaju u interakciju sa magnetosferom, što dovodi do različitih geomagnetnih poremećaja.Geomagnetna aktivnost direktno je proporcionalna intenzitetu sunčevog zračenja koje dolazi do Zemlje. Pod uticajem sunčevog korpuskularnog zračenja dolazi do pojave geomagnetnih bura koje su praćene porastom intenziteta magnetnog polja.Količina i jačina dolaznog sunčevog zračenja zavisi ...... polja koje je izazvalo datu buru bio jJak i da je formiranje prstenaste struje oko Zemlje trajalo kratko.

Using gravity data to define structural correlation affecting the formation of Neogene basins
A gravity survey can help to define the structural correlation in the study area. The structures that have influenced the development of Neogene basins can be defined using gravity data. By applying mathematical transformations to gravity data, the geological structures (faults, nappes, etc.) that impacted the formation of Neogene basins can be defined. We have taken the part of the Dinarides as the test region. The paper presents the results obtained using the procedure residual, vertical gradient, and total ...Snežana Ignjatović, Ivana Vasiljević, Branisav Sretković, Milanka Negovanović.
