LANDSLIDE ON LOCATION OF WATER SOURCE STUDENAC NEAR BIJELJINA, REPUBLIKA SRPSKA

The landslide is located in the hinterland of water source "Studenac" in the local community Gornja Cadjavica near Bijeljina. The field where the triggered landslide occurred is conditionally stable slope. It is overgrown with forest trees and therefore it was not a subject of interest in terms of its stability until the water source and accompanyi...

SEISMIC ACTIVITIES AND SEISMOTECTONIC FAULTS IN BOSNIA AND HERZEGOVINA

Earthquakes are one of the biggest hazards of humanity. Even today it is not possible to predict the exact magnitude, location and time of an earthquake, but, nevertheless, modern seismology and science are able to point to the potential danger and risk of earthquake-like movements in an area, at one time. Some of the signs that announce the earthq...

APLICATION OF LOCAL CEMENT FOR CEMENTING OIL WELLS IN THE SOUTH EASTERN REGION OF THE PANNONIAN BASIN

Wells conditions are different in wide range of temperature and depth. Cement slurries in such conditions have to remain pumpable and after setting to stay homogenous in production well life. For cementing operations in wide range of temperature and pressure and to accommodate cement slurries for individual well requirements more than 50 additives ...

THE ANALYSIS OF THE EFFECTS OF IWA METHODOLOGY APPLICATION ON WATER SUPPLY SYSTEMS IN BOSNIA AND HERZEGOVINA

The key problem of water utility companies in Bosnia and Herzegovina in the fight to reduce the level of non revenue water (NRW) is the lack of a unique methodology with clearly defined steps. The aim of this paper is to show the possibility of accepting the concept for the control of water loss in water supply systems, which provides the Internati...

SURFACE AND STRUCTURE STUDY OF CLAY-BASED COMPOSITES AFTER THERMAL TREATMENT

The composite materials prepared from clay and iron oxides in different weight ratios and temperatures denoted as A85 and E20 were heated at 300 °C in reductive atmosphere and up to 650 °C in inert atmosphere. The changes in the structure, surface and pore properties were examined by XRD, N2 adsorption method and TG, DTA method. The morphology was ...

pH OF PRECIPITATION IN THE AREA OF THE TOWN OF BIJELJINA

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...
