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...

COPPER RESISTANCE OF LAWN GRASS AND CHRYSANTHEMUM CARINATUM PLANTS
Condition and quality of the lawn grass and flowering plants is important indicators of the level of landscaping and the urban environment. Copper ions significantly reduce the quality of ornamental plants. The aim of this study was to assess phytotoxicity of copper for Chrysanthemum carinatum, Festuca rubra and Agrostis stolonifera.High contaminat...

ELIMINATION OF TOXIC ELEMENTS BY NATURAL AND SYNTHETIC ADSORBENTS
The adsorption of Zn(II) and Cu(II) onto siderite (S) and kaolin (K) and adsorption of As(V) onto bentonite (B) was studied. The chemical modification – precipitation of MnO2 on the kaolin (KM) and siderite (SM) surface was used to improve the adsorption properties of natural materials for their application in columns. In the batch tests the higher...

THE INFLUENCE OF OCEAN TIDES TO DETERMINE THE EARTH'S ORIENTATION PARAMETERS
The paper deals with the themes of the Earth's orientation and rotation. The parameters of the Earth's orientation can be determined by several methods. The emphasis in this paper is the influence of ocean tides to determine the parameters of the Earth's orientation with one of the space-geodetic techniques, called Very long baseline interferometry...

VARIATION CONCENTRATION OF SULFUR DIOXIDE AND CORRELATION WITH METEOROLOGICAL PARAMETERS
Levels of SO2 in air samples from urban zone of Banja Luka were determined at locality Center in Banja Luka (administrative center of the Republic of Srpska, in Bosnia and Herzegovina) which is highly populated area, with intensive traffic and industry. Through experimental measuring, daily and weekend variation of SO2 concentration was determined....

COENOLOGICAL SIMILARITIES OF DIATOMS IN WELLS AND IN OTHER WATER BIOTOPES IN BOSNIA AND HERZEGOVINA
The research and determination of diatoms (Bacillariophyta) have been carried out in the area of Semberija (Bosnia and Herzegovina) in several locations, which included 35 open shadoof wells incurred by the anthropogenic activity many decades ago, and they represent artificial fresh water ecosystems. The algological material has been collected from...

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...
