ESTIMATION OF THE CALIBRATION MEASUREMENT CAPABILITY OF MECHANICAL CALIBRATION LABORATORY
The calibration measurement capability - CMC is defined as the smallest uncertainty that a laboratory can achieve within its powers when carried out more or less daily calibration of nearly ideal measurement standards intended to define, generate, keep or renew units of that size, or one or more of its value, or when carried out more...

CHROMATIC SELECTIVITY OF OPTIC PROPERTIES OF NANOSCOPIC FILM-STRUCTURES IN IR REGION
Based on microscopic (exciton) theory of optical properties of symmetrically perturbed ultrathin molecular films, the absorption, reflection and transparency indices were formulated and presented in the function of frequencies of external electromagnetic field in near IR region. It has been showed that all optical properties depend o...

MINING HOTSPOTS-POTENTIAL IN EXPANDING THE CHEMICAL AND PHYSICAL APPLICATIONS OF NANOMATERIALS
Nanometalic materials are at the present moment the most commercialized class of nanomaterials. Methods for their synthesis and exploitation of the physical phenomena of their behaviour on atomic level are ever-expanding. Their prices are sometimes too high and in lowering the price, finding the new recourses of raw materials, would ...

DEPOSITION OF Al THIN FILM ON FeCrAl ALLOY AND CONTINUOUS ELECTRICAL RESISTANCE MEASUREMENT
FeCrAl alloys are used in a wide range of resistance and high-temperature applications such as wire heaters, furnace structure parts, etc. Their oxidation resistance at elevated temperatures relies on the formation of a thin and a continuous Al2O3 layer on the alloy surface. Growth and thickness of the protective Al2O3 layer depends ...

OPTIMIZATION OF DESIGN SOLUTIONS OF MAIN GIRDERS OF “TYPE A” FOR THE PREFABRICATED PRESTRESSED CONCRETE INDUSTRIAL HALLS FOR SERVICEABILITY AND DURABILITY ACCORDING TO EC 2
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 ...

INFLUENCE OF MICRONIZED GRINDING FILLER ON THE RHEOLOGICAL PROPERTIES OF COATINGS BASED ON CORDIERITE
For the development of refractory coatings with controlled rheological properties the influence of micronized milling process was investigated. Change the properties of fillers based on cordierite, primarily on changing the size and shape of grain fillers, dispersion and stability of the suspension of the coating was investigated, al...

MEDIEVAL FORTRESSES IN BOSNIA AND HERZEGOVINA - CAUSES, CONSEQUENCES, REMEDIAL STEPS, INTERVENTIONS AND UPGRADING TECHNIQUES
There is something inherent, compelling and mystified in ruins and remains of the old fort. The issues logically imposed at the first encounter with these witnesses of the past are linked to their current condition, age and role in history. Historically, all those fortresses were more than the fortified military structure. They have ...

THE WATER FILTRATION TECHNOLOGY SELECTION FOR WELL „KRUŠČICA“
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...

RECYCLING REFRACTORY WASTE FROM THE IRON AND STEEL INDUSTRY
Refractory materials are an important part of industrial furnaces and metallurgical aggregates. With time and use, the wear out of refractory materials ocures and their replacement becomes necessary. Part of refractory material, which is removed after the demolition of industrial furnaces and metallurgical unit refractory linings, represents refrac...
