AN ANALYSIS OF THE INFLUENCE OF AIR TEMPERATURE AND HUMIDITY ON OUTDOOR THERMAL COMFORT IN BELGRADE (SERBIA) USING A SIMPLE HEAT INDEX
The main objective of this paper is to study the outdoor thermal comfort of the central urban zone of Belgrade during summer season in order to examine how different bioclimatic conditions affect human body. For this purposes Humidex, a simple heat index was applied. The research involved analyzing different Humidex values, the so-called “sub-indic...

EXPOSURE TO NON-IONIZING RADIATION OF AREA IN URBAN ZONE OF THE BANJA LUKA CITY
Intensity of electromagnetic pollution is followed by rapid increasing of new telecommunication technologies over the years. In order to prevent enlarged exposed of general population with doses of electromagnetic radiation above allowed for general population, living as well as working environment around antenna systems should be tested. Using sop...

HUMIC ACIDS OPTICAL PROPERTIES OF RENDZINA SOILS IN DIVERSE ENVIRONMENTAL CONDITIONS OF SERBIA
This study examined the impact of climate, altitude and landforms on humic acids (HA) optical properties (E4/E6, ∆logK, RF indexes) in Serbian Rendzina soils. HA humification degree of calcareous and decarbonated Rendzinas under natural vegetation (forest and grassland, separately) decreased with altitude increasing. This particular rule was not ma...

DETERMINATION OF AIR REFRACTION INFLUENCE ON TRIGONOMETRIC HEIGHT DIFFERENCES
Efficiency of trigonometric levelling method for height differences determination is better than those determined by geometric levelling but its accuracy is significantly lower. Development of accuracy of geodetic instruments increases possibilities for improvement accuracy of trigonometric levelling.However, air refraction appears as ultimate limi...

ANALYSIS OF TIME OSCILLATIONS OF WATER ON LAKE MODRIC AS A MULTI-PURPOSE RESERVOIR
The major task of multi-purpose reservoir „Modrac“ operation is to decide how much water should be released now and how much should be retained for future use given some available and/or forecasted information at the beginning of the current time period. In practice, reservoir operators usually follow rule curves, which stipulate the actions that s...

RESEARCH METHODOLOGY OF RAILWAY ROUTE DOBOJ – ZENICA, SECTION km 103+500 – MAGLAJ
Researched section of the railway route presents a part of the route from Sarajevo to Doboj, built with two tracks. First track was built in 1947, and the second in 1978. In construction methods are present differences, considering the time when it was constructed and the way of construction. Both tracks were used for years for movement of trains o...
