A methodology for assessing the pressures on transboundary groundwater quantity and quality – experiences from the Dinaric karst
Zoran Stevanović, Veljko Marinović (2020)A relatively novel and abridged methodology for assessing the quantity and quality status of groundwater bodies has been applied in the Dinaric karst of SE Europe. Validation of pressure on quantity is based on groundwater budgeting and the correlation of available groundwater reserves and projected water demands, while pressure on quality is estimated by GIS-created maps: vulnerability – hazard – risk. The results obtained from the studied groundwater bodies indicate mostly low pressure on water quantity, but increased risk from diffuse and point pollution sources. ...Zoran Stevanović, Veljko Marinović.

Процјена хазарда и ризика од клизишта за различите нивое просторног планирања у Републици Српској, БиХ
Цвјетко С. Сандић (2022)Територија Републике Српске је у посљедних десетак година веома угрожена активирањем нових и реактивирањем старих клизишта. Она својим дјеловањем наносе огромне материјалне штете, па и људске жртве, те је неопходно озбиљније третирање и дјеловање у борби са овим природним хазардом. Чест проблем јесте одговорност, тј. надлежност институција из ове области и недостатак у законској регулативи која готово никако или само површно обрађује област хазарда и ризика од клизишта.

A new polymorph of Ba(AsO3OH): Synthesis, crystal structure and vibrational spectra
Tamara Đorđević, Ljiljana Karanović (2010)A new monoclinic polymorph of Ba(AsO3OH) was synthesized under hydrothermal conditions. It represents a previously unknown structure type.

Hydrodynamic analysis of radial collector well ageing at Belgrade well field
The origin and effect of hydraulic resistances on the rate of ageing of radial collector wells are identified through numerical hydrodynamic analysis. The research includes hydrodynamic modeling of one such well with new laterals at Belgrade well field. The performance of the laterals is aggravated by rapid ageing. The change in the hydraulic parameters of the laterals during the first decade of operation is analyzed through simulations of the groundwater regime with realistically specified geometries and hydraulics of the ...Đorđije Božović, Dušan Polomčić, Dragoljub Bajić, Jelena Ratković.

Потреба за израдом биланса и оценом расположивих резерви подземних вода Републике Србије
Природне карактеристике Србије, просторна дистрибуција ресурса водe и њихових корисника, као и међусобна интеракција коришћења, заштите вода, као и заштите од вода, условиле су да се подземне воде на читавој територији морају посматрати интегрално, јединствено, комплексно и рационално. Међутим, тренутно је у Републици Србији могуће дефинисати само одлике појединих издани и/или изворишта услед непостојања довољних података за свеобухватну анализу стања ресурса.

Against the tide: southeast to northwest shelf-edge progradation in the southeastern margin of Lake Pannon, Banat (Serbia and Romania)
In the late Neogene, the Pannonian Basin in Central Europe was filled with sediments when rivers from the Alps and Carpathians shed their sediment load into Lake Pannon. The most powerful source-to-sink system was that of the paleo-Danube, transporting sediments from the NW as far as the southeastern part of the lake. In the southeastern margin of the basin, however, local sedimentary systems worked in the opposite direction, against the “tide” of the prevailing N to S sediment transport. ...Dejan Radivojević, Miloš Radonjić, Lajos Tamás Katona, Imre Magyar.

Integrated energy planning approach for accelerating energy transition of households
The success of energy transition planning depends on several influential and variable factors that need to be considered and tracked in modeling to support policymakers. Expert-based energy models are mainly developed following the assumptions of experts and, in most cases, a limited number of stakeholders. This top-down modeling approach will provide satisfactory results in centrally managed energy sectors (electricity generation and distribution, district heating, etc.), where further decisions could be projected relatively precisely. However, the same approach will not ...Energetsko planiranje, Integrisano energetsko modeliranje, Energetska tranzicija, Domaćinstva, Individualno grejanje, LEAPBoban Pavlović, Marija Živković, Dejan Ivezić.
