REASONS TO CHANGE THE TENDER PROJECT OF A TUNNEL DURING CONSTRUCTION
During construction, especially of tunnels, very often there is a need to change the tender technical documents, i.e. the documents upon which the construction permit is obtained and the tender is announced. The main reason for the change of documentation is, above all, unsuficient geotechnical investigations due to which technical solutions and ca...

AN EXAMPLE OF „MODERN CONSTRUCTION OF THE FACILITY“
Today's building of facilities does not follow the study of the characteristics of the terrain on which the facility is constructed. The period of rapid construction, which can be called the "modern construction" does not follow the quality of constructed facilities. Usually it is the uncontrolled building, where is only important to build a facili...

SORPTION OF COPPER AND ZINC BY GOETHITE AND HEMATITE
In the present work, the abilities of natural and synthetic samples of goethite and hematite to remove copper Cu(II) ) and zinc Zn(II) ions from aqueous solutions were compared. Batch adsorption experiments were performed in order to evaluate the removal efficiency of iron oxide samples. The effect of initial metal ion concentration, initial pH and...

IMPORTANCE OF OLISTOSTROME MEMBER FOR METALLOGENY OF LJUBIJA IRON ORE DEPOSITS
Ljubija mining area is built of more formations that belong to the Carboniferous, Permian, Triassic and Cenozoic. From all of these, only two are metalliferous to iron: Javorik formation with olistostrome member and Neogene-Quaternary of Prijedor basin. The first includes primary siderite and ankerite partially limonitised ore and in the second onl...

INFLUENCE OF ENVIRONMENTAL CONDITIONS ON CARBON AND NITROGEN CONTENT IN SERBIAN RENDZINA SOILS
Organic matter in Serbian Rendzina soils dependence on altitude and geographic regions was investigated. There was no regular dynamics of carbon and nitrogen content nor in C/N ratio, probably because of slight climatic variation among altitudes and regions, thus negligible differences in vegetation, organic litter and decomposition dynamics. Predi...
