Particulate matter (PM) is hazardous to human health. This paper deals with PM concentrations in ambient and indoor air on three locations (two being in the central parts of the city and another onenear industrial zone of the settlement of Lazarevac, lying in the outskirts of Belgrade). The aim of the paper is to assess the scope of exposure to par...

Before the electronic distance meters appears the angles measuring dominated in geodetic networks. Development of distance measuring technology and appearance of automated total stations almost equaled the efficiency of measuring angles and distances. This fact allows designer of geodetic networks to combine angles and distances in order to achieve...

This paper presents one approach for the analysis of snap behaviour of simply supported elastic shallow shells. Structure is discretized with the finite strip method. Displacement field is approximated with series of products of polynomials and harmonic functions. Only geometric nonlinearity of von Karman type is considered. Equilibrium equations a...

Presence of certain polluting substances in the atmosphere causes disturbance of natural pH values that leads to acidic precipitation occurrence. Measurement of pH of precipitation in the area of the town of Bijeljina has been done since 2008 and the sampling has been performed at three points. This paper presents measurement results of surveys for...

Field research for the purpose of the construction of the Thermal Power Plant Ugljevik 3 wasconducted in two phases. In the first phase for the smaller scope of the fieldworks, more laboratory analyses were performed. In the second phase, fieldworks were conducted in a larger scaleand laboratory analyses were considerably smaller.Designers dictated...
