THE EVALUATION OF THE STRUCTURE AND HARDNESS OF DENTAL Ti-Zr ALLOYS
Many types of alloys are available as dental implants, but titanium and its alloys have been widely used due to their outstanding properties. In this research titanium alloys with different Zr contents were prepared by arc-melting. Phase identification was performed by XRD analysis. Microstructure was observed by light microscope aft...

EEFFECT OF VARIATIONS IN CHEMICAL COMPOSITION ON QUALITY OF HOT ROLLED AND DRAWN WIRE
Ratio of ultimate tensile strength and yield stress shows lower values in cold drawn wire than in hot rolled state. The results of research addressing the effect of variations in chemical composition of continuous casted billets on mechanical properties of cold-formed wire used in production of steel mesh are presented. In the c...

THE EFFECT OF DIFFERENT TYPES OF FLY ASH ON SELFCOMPACTING CONCRETE PROPERTIES
In this paper the effect of two different fly ash types on the properties of self-compacting concrete in fresh state and hardened state was investigated: fly ash from Thermal power plant “Kakanj” and fly ash from Thermal power plant “Tuzla”. The results of testing fresh self-compacting concrete properties show that addition ...

ESTIMATION OF PARTICULATE MATTER CONCENTRATIONS AT SOME POPULATED CENTERS AROUND SHKODRA LAKE USING SYNERGISTICALLY IN-SITU MEASUREMENTS AND REMOTE SENSING TECHNIQUES
Lake of Shkodra as the largest lake in the Balkan Peninsula forms a relatively complex ecosystem. One of the most important indicators of this ecosystem is also the quality of air. Air quality can be estimated based on several viewpoints, using physical or chemical parameters. In this study, the work is based on estimation of particulate matter con...

SULFUR DIOXIDE AIR POLLUTION IN THE CITY OF ZENICA
In the city of Zenica steel is continuously produced more than 120 years. In all technological stages of production and processing of steel within integrated steel works large amounts of raw materials and fuels which contain a certain amount of sulfur are consumed. The flue gases formed during production and processing of steel contain certain conc...
