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...

The paper presents the potential areas in Bosnia and Herzegovina (BiH) for injecting CO2 into underground geological formations by boreholes. Areas are determined based on the geological structure of Bosnia ana Herzegovina, and development of Miocene formations which are the most prevalent in the northern and northeastern parts of the country, in t...

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 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...

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 ...

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...

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...

U ovom radu prikazani su rezultati mjerenja koncentracije aktivnosti radona u seizmički aktivnim zonama Tuzlanske regije. Od velikog broja metoda za mjerenje koncentracije aktivnosti radona izabrana je metoda trag detektora tipa CR39, koji su pogodni za dugotrajna mjerenja radona, od nekoliko dana do više mjeseci, pri čemu dobijeni rezultati predst...

Moguće je uspostaviti određene korelacije između geotehničkih parametara tla dobijenih u laboratoriji i na terenu, kao i indeksnih parametara. Ovi parametri bili bi utvrđeni na osnovu rezultata israživanja i ispitivanja koji bi obuhvatili: • geološke, inženjerskogeološke i hidrogeološke radove • istražna bušenja • standardna dinamičk...
