Mine development imposes very high technical requirements of the mine hoisting equipment in terms of speed of transport. To meet these requirements it is necessary to properly design the structural elements of mine hoisting equipment which means that they must have the proper characteristics of the materials from which they are made such as mechani...

This paper presents an experimental study to evaluate the possibility of CEM IV 42,5N producing by increasing the specific cement surface from 3180 to 3850 cm2 /g. In this paper, fly ash is used as a cement admixture because fly ash possesses both hydraulic and pozzolanic properties. If one part of the clinker, as a major cement admixture, is repla...

The results of two light optical tomographies (LOT) of two-phase steels are presented and compared in this paper. Two-phase steels show a microstructure consisting of a carbon-rich second phase and a ferritic matrix. In this work, microstructures are compared with a martensitic and a bainitic second phase. Tomographies are very important for materi...

Urban environments are subject to various pollutions where, among other things, acoustic pollution. Consequently, the study of acoustic pollution is an issue that is addressed in several aspects: economic, political and scientific / research.In this paper we propose a simulation model through the Matlab / Simulink software that shows the effect of ...

The great development of the industry has caused the need for systematization in the classification of raw materials and finished products. For this reason, all industrialized countries have their own standards, so called national standards or norms for production and delivery. With the unification of European countries, and also for the import and...

Basic raw materials for paper production are cellulose fibers and water. Water plays a major role in the process of cellulose and paper production and it is present in almost all phases of the cellulose fiber production process. Because of that the cellulose and paper industry is considered to be one of the largest consumers of natural resource pol...

The regulations on air quality in Bosnia and Herzegovina are based on European Union regulations and they rely on defined limits for concentrations of certain pollutants. Although the law stipulates that the public must be informed on the quality of environmental parameters in a clear, simple and easily understandable manner, this is not the case i...

In the following paper results of the investigation of the “Bauschinger effect” are presented. It was done by model which was made in ABAQUS and observed from deep rolling simulation results of residual stresses. Later, comparison of the results are presented by variation of forces and overlapping factor. Deep rolling (DR) is a mechanic...
