Стање квалитета амбијенталног ваздуха на подручју града Панчева
Александар Маринковић (2024)Квалитет ваздуха је кључни фактор за здравље људи и очување животне средине. У овом завршном раду анализирано је стање амбијенталног ваздуха на територији града Панчева како би се сагледали извори загађења, ПЛН мониторинга и изазови у погледу квалитета ваздуха са којима се суочавају сви становници. Кроз примену савремених метода праћења, идентификовани су главни извори загађења и анализирана је дистрибуција загађујућих материја у урбаном окружењу.Праћењем концентрације загађивача као што су честице PM10, PM2.5, сумпор-диоксид (SO2), азот-диоксид (NO2) и други, ...... |Ilapa/{ymaga (a),(Mc) SO», BTX, NO:, NO, NOx Ox, CoO 2.

Fuzzy optimization in hydrodynamic analysis of groundwater control systems: Case study of the pumping station “Bezdan 1”, Serbia
Dragoljub Bajić, Dušan Polomčić (2014)A groundwater control system was designed to lower the water table and allow the pumping sta-tion “Bezdan 1” to be built. Based on a hydrodynamic analysis that suggested three alternative solutions, mul-ticriteria optimization was applied to select the best alternative. The fuzzy analytic hierarchy process methodwas used, based on triangular fuzzy numbers. An assessment of the various factors that influenced the selec-tion of the best alternative, as well as fuzzy optimization calculations, yielded the “weights” of the alternativesand the ...groundwater lowering, groundwater management scenario, fuzzy analytic hierarchy process,expert knowledge, triangular fuzzy numbers, linguistic variables... modeling, in this case to define a groundwater control system for the “Bezdan 1” PS, is a common approach in modern hydrogeology.

Towards resolving Cretaceous to Miocene kinematics of the Adria-Europe contact zone in reconstructions: Inferences from a structural study in a critical Dinarides area
One key element in the current debate analysing the Central Mediterranean evolution is the Cretaceous structure and kinematics of the present-day oroclinal bent contact between Adria-and Europe-derived continental units in the Dinarides, interpreted in different tectonic reconstructions as a subduction-related thrust system or a large-scale strike-slip fault zone. We provide a solution to the debate by a structural and kinematic study in a key area located in central Serbia along the Europe–Adria orogenic suture of the Sava Zone.

Availability as a dimension of energy security in the Republic of Serbia
Boban Pavlović, Dejan Ivezić (2016)There is a range of modern approaches and models in literature for the evaluation and determination of energy security, which are based on different parameters and indicators. For most of them, a common characteristic is emphasizing the avail ability of energy, as an important dimension for ensuring energy security. In this paper, concise overview of Serbian energy sectors is given and appropriate energy indicators are defined and determined. Selected indicators provide insight into the main components that characterize availability ...... is to measure the availability of national stocks of critical fuels with respect to corresponding fuel consumption [8].

Утицај промене нивоа подземне воде за услове плитког фундирања у крупнозрном тлу
Милана Мичета (2024)Подземне воде представљају изузетно важан природни ресурс, као и важну компоненту система, којим је представљено тло. У складу са тим, приликом пројектовања плитких темеља на крупнозрном тлу, односно приликом анализе граничне носивости и слегања, треба узети у обзир и утицај воде. Верује се да ниво подземне воде значајно смањује носивост тла, док се слегања значајно повећавају. Terzaghi (1943) је први сугерисао да се потапањем масе тла, његова носивост смањује за половину, док се слегање удвостручује.
