GIS ANALYSIS OF THE VULNERABILITY OF FLASH FLOODS IN THE POREČKA RIVER BASIN (SERBIA)
The aim of this study is to identify and map the zones of different vulnerability to flash floods based on the geospatial analysis of natural conditions in the Porečka River basin (Republic of Serbia). The analysis covers the catchment area of the Porečka River (493.82 km2 ). Geospatial analysis was conducted using GIS software (QGIS 3.18). The Fla...

THERMAL COMFORT IN BELGRADE, SERBIA: UTCI-BASED SEASONAL AND ANNUAL ANALYSIS FOR THE PERIOD 1991-2020
The main goal of this research is to examine thermal comfort in the central area of Belgrade (Serbia), over a period of 30 years (1991-2020). The Universal Thermal Climate Index (UTCI) was used as a measure for evaluating outdoor thermal comfort (OTC). The obtained results were considered separately for each season, as well as at the annual level. ...

APPLICATION OF HYBRID SFLA AND ACO ALGORITHM TO OMEGA PLATE FOR DRILLING PROCESS PLANNING AND COST MANAGEMENT
Tool traveling and tool switching time constitute almost seventy percent (70%) of the total timeconsumed in drilling process. This fact that 70% of the total time is nonproductive and does not add any value to the job, grabs attention of the researchers and the industrialist for optimization. A literature on drilling process revealed that very few ...

CONTROL FACTORS OF IRON MINERALIZATION IN THE METALLOGENY OF THE LJUBIJA ORE REGION
The control factors of mineralization in the Ljubija ore region are stratigraphic, lithological, magmatogenic, structural-tectonic and hypergenic. The distribution of iron ores in the Ljubija ore region is primarily controlled by the spread of the Olistostrome member of the Carboniferous Javorik flysch formation. Only that member, whether uncovered...

CORRELATION AND REGRESSION RELATIONSHIPS OF PARAMETERS OF RAINWATER DRAINAGE FROM ROADS
In order to find the optimal solution for the drainage of rainwater from roads in urban areas, as well as for the evaluation and ranking of conceptual solutions, appropriate mathematical models and software packages were used in this research. For relevant rain episodes, i.e. rainfall of appropriate duration and intensity, runoff coefficients and f...

ON THE ABRASIVE WEAR HIGH STRENGTH COATING LAYERS ON MACHINE PARTS TESTING
Plasma coating technology was applied to machine parts. During application, the jet formed hits the surface of the material and particles are deposited on the surface. In this way, layers of high thickness can be applied and thus revitalize worn machine parts. The paper examines the abrasion resistance of Al2O3 and Al2O3 phosphate layers applied to...

STRATEGY OPTIMIZATION FOR RESPONDING TO PRIMARY, SECONDARY AND RESIDUAL RISKS CONSIDERING COST AND TIME DIMENSIONS IN PETROCHEMICAL PROJECTS
Risk management throughout the project life cycle, from the initial phase beginning to the final phase, ended continuously and dynamically, is one of the basic requirements for the success of any project oriented organization. To effectively identify and manage risks at all stages of the project, careful selection must be made at all levels of the ...

THE SIGNIF ICANCE OF HARVEST RESIDUES IN THE SUSTAINABLE MANAGEMENT OF ARABLE LAND. II. HARVEST RESIDUES MANAGEMENT
Harvest residues (HR) are one of the important aspects of sustainable management in agriculture, representing a significant portion of organic matter (OM) that can be retained or removed from agroecosystems. There are several ways to manage plant residues: (i) burning, (ii) incorporation in soil, (iii) leaving plant residues after harvest on the s...

COMPARATIVE ANALYSIS OF OLD-GROWTH STANDS JANJ AND LOM USING VEGETATION INDICES
Old-growth forests represent a very valuable field for research of natural processes. The application of remote sensing was carried out on two old-growth forests in the northwestern part of the Republic of Srpska. The sample plots from OG Janj show relatively higher mean values (NDVI, SAVI and EVI) compared to OG Lom, with the exception of the VARI...
