VERTICAL DISTRIBUTION OF DIATOMS ON MOSSES IN WELLS OF BIJELJINA MUNICIPALITY IN BOSNIA AND HERZEGOVINA
Vertical distribution of species and infraspecies taxa of diatoms (Bacillariophyta) on well mosses where they live epiphytically, and a relative number of individuals per surface area unit were followed in 8 open wells with shadoof. Researches were conducted during 2015-2016 through four seasons. Sampling of algae material from well mosses that cov...

SOIL AND RADIONUCLIDES OF EASTERN HERZEGOVINA
Soil is one of the most important natural resources. Measurement of natural radioactivity in soil is very important to determine the amount of change of the natural background activity with time as a result of any radioactivity release.Coal mine and thermal power plant in Gacko field is a very important industrial facility. The content of radionucl...

RESEARCH METHODOLOGY OF RAILWAY ROUTE DOBOJ – ZENICA, SECTION km 103+500 – MAGLAJ
Researched section of the railway route presents a part of the route from Sarajevo to Doboj, built with two tracks. First track was built in 1947, and the second in 1978. In construction methods are present differences, considering the time when it was constructed and the way of construction. Both tracks were used for years for movement of trains o...

STUDY OF Cu(II) ADSORPTION BY BENTONITE AND FOLLOWING REGENERATION BY BIOLEACHING
The natural bentonite and bentonite/iron oxide composite were used as sorbents of Cu(II). Their sorption properties were examined under the different conditions such as pH of the solution, initial metal ion concentration. The bentonite removed 71 % Cu(II) while composite 90 %. Their maximum adsorption capacities were 34.1 and 44.4 mg Cu(II) g -1, r...
