Hydrographic and hydrological characterization of the Vodenička and Rosomačka rivers
Vesna Ristić Vakanjac, Marina Čokorilo Ilić, Dušan Polomčić, Dragoljub Bajić, Jelena Ratković (2017)The Visočica River rises in Bulgaria, on the Berovo Mountain. Its course in Bulgaria is 16.7 km long. It enters Serbia near the village of Donji Krivodol. Up to the village of Pakleštica, or the beginning of Lake Zavoj, its right-bank tributaries are the Krivodolštica, the Vodenička, the Rosomačka and the Dojkinačka. There are no left-bank tributaries. Among the tributaries, water levels and discharges are gauged only on the Dojkinačka River. The Vodenička had also been gauged but only ...Vesna Ristić Vakanjac, Marina Čokorilo Ilić, Dušan Polomčić, Dragoljub Bajić, Jelena Ratković.

Groundwater as an important resources in emergency situations of the Republic of Serbia
Boris Vakanjac, Radoje Banković, Vesna Ristić-Vakanjac, Saša Milanović, Ljiljana Vasić, Saša Bakrač, Nikola Kozić (2024)Groundwater is a renewable resource wholly or partially protected from external influences (pollutants) by nature. Currently, about 75% of the population of the Republic of Serbia meets its water needs by using underground water. Hence, this water represents an essential strategic resource of our country; according to data from the Water Management Foundation of the Republic of Serbia (VOS, 2001), water from existing sources is used in quantities of about 23 m3/s. As 67.13 m3/s is the estimated potential ...Boris Vakanjac, Radoje Banković, Vesna Ristić-Vakanjac, Saša Milanović, Ljiljana Vasić, Saša Bakrač, Nikola Kozić.

A new evidence for pachyostotic snake from Turonian of Bosnia-Herzegovina
Фосилни налази морских змија из кредних седимената Босне и Херцеговине познати су од пре скоро сто година. У овом раду је приказан нови налаз пахиостотичне змије пронађене у локалном каменолому Дубовац, око три километра северозападно од Билеће. Примерак чини низ од 29 кичмених пршљенова од којих су седам изоловани из седимента. Међу изолованим пршљеновима два најочуванија су својим скоро четвртастим обликом слична пршљеновима Simoliophis rochebrunei али су неурални луци више отечени.

Upper Miocene depositional environments of the Kikinda-Mokrin High (Serbia)
Saša Ivanišević, Dejan Radivojević (2018)Exploration for oil and gas in mature areas, such as the Pannonian Basin, can benefit from reexamination of old data using more advanced modern workflows that focus on the temporal and spatial aspects of sediment deposition. Specifically, we apply a new environment of deposition model that interprets the Upper Miocene- Pliocene sediments as being deposited in a rapidly filling basin characterized by quick shelf edge progradation from the northwest toward the southeast. Reconstruction of this shelf edge trajectory reveals ...... tion of adjacent SCD (Matenco and Radivojević, 2012). The onset of a marine transgression is recorded during Middle Miocene.

Natural two-dimensional pyrophyllite: Nanoscale lubricant, electrical insulator and easily-machinable material
Borislav Vasić, Radoš Gajić, Ivana Milošević, Žarko Medić, Marina Blagojev, Marko Opačić, Aleksandar Kremenović, Dejan Lazić (2022)Pyrophyllite, with the chemical formula Al2Si4O10(OH)2, is a naturally occurring and abundant van der Waals mineral belonging to the group of phyllosilicates. It is very soft, layered crystal used for sculpting and an excellent electrical and thermal insulator aimed for the operation at high pressure and temperature. Here, for the first time, two-dimensional (2D) pyrophyllite obtained by both mechanical and liquid phase exfoliation is presented and investigated at the nanoscale. The layered structure provides low friction coefficient of around ...Atomic force microscopy, Insulating properties, Nanofriction and wear, Natural two dimensional materials, Phyllosilicates, PyrophylliteBorislav Vasić, Radoš Gajić, Ivana Milošević, Žarko Medić, Marina Blagojev, Marko Opačić, Aleksandar Kremenović, Dejan Lazić.

Tracking of the temporal dependency of fading of the human footprint temperature contrast
In certain situations, it is extremely important to determine the exact time “someone” entered or crossed the forbidden zone of a military or strategic installation, a red zone of radioactive, chemical, or biological contamination, a bank or similar structure. Standard security measures include ordinary video surveillance using cameras that operate in the visible range of the electromagnetic spectrum, as well commercial thermal imaging cameras [1, 2]. The paper presents the results of experiments that suggest another possible use of ...Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Darko Vasiljević, Danica Pavlović.
