The application of nanotechnology in medicine and dentistry will bring significant advances in the diagnosis, treatment, and prevention of disease. Various applications of nanotechnology in medicine are responsible for development of a new branch of medicine, called nanomedicine, which shows how it is possible to improve the understanding of pathop...

Non-metallic inclusions usually deteriorate mechanical properties and surface quality of steel products. Presence of non-metallic inclusions might have negative affected some of the mechanical properties of steels like ductility, toughness, anisotropy, and formability. Macroscopic method for assessing the content of non-metallic inclusions in forge...

In conducted research was made a characterisation of microstructure and powder NiCrAlY, before and after applying on the base material. Coating was carried out by using HVOF Diamond Jet procedure, which uses the kinetic energy of the metal particles produced by on explosion of combustible gases. Characterisation was based on chemical analysis of me...

Carburizing is a very popular method of thermochemical treatment to increase the surface hardness of steel parts. It is achived by heating the steel at an austenite temperature in an environment of appropriate carbon source. Carbon sources provide the corresponding so-called a carbon potential (C potential). In the case of equilibrium state, the ca...

Research focus of this paper are stresses in concrete, reinforcement and tendons, cracks and deflections of the prestressed girders of “Type A” in order to optimize the span of such girder for the same amount of tendons and reinforcing steel. Serviceability Limit State (SLS) is a condition in which construction ceases to ...

Water that is commonly used for drinking is groundwater, that appears on the surface of the Earth's crust as sources of different types and capacities, and in most cases that water is chemical, physical and bacteriological acceptable and suitable for use. In some cases, there is some blurring of water, that is the result of heavy rainfall or some h...
