Structural condition and repair of the Careva Ćuprija Bridge in Sarajevo is presented in the paper. This historic structure has been exposed to various atmospheric influences during its use, and also to significant traffic load for which it was not initially designed, which has ultimately resulted in degradation of its structure. To enable continued functioning of this bridge its structure must be repaired taking into account the fact that the bridge was proclaimed a national monument of Bosnia and Herzegovina on 11 March 2009.

Abstract: According to the World Bank, more than one quarter of worlds’ population is without a bank account and is excluded from financial system. Improving financial inclusion and building inclusive financial systems is in agenda of all policy makers in both developed and developing countries aiming to include the poorest part of the population in to the financial system. Financial inclusion is becoming more important topic in academic world, but also among regulators and policy makers. In order to emphasize the importance of financial inclusion, this paper investigates the extent of financial inclusion among Western Balkan countries and in comparison to other developing regions around the world. Using data from the World Banks’ Global Findex data base, this paper provides comparison of the level of financial inclusion in Western Balkans counties, focusing on the importance of government role in increasing financial inclusion. Research shows similar level of financial inclusion within Western Balkan countries measured by the following indicators of financial inclusion: percentage of population having formal account at a financial institution, percentage of population saving at financial institution and percentage of population borrowing at financial institution. Furthermore, the research shows that the level of financial inclusion in Western Balkan countries is slightly above the levels in other developing regions around the world, but still Western Balkan countries lack national financial inclusion strategies which will help increase their levels of financial inclusion to the level of more developed countries. Keywords: financial inclusion, Western Balkan countries, developing regions, national financial inclusion strategies, policy makers

According to the World Bank, more than one quarter of worlds’ population is without a bank account and is excluded from financial system. Improving financial inclusion and building inclusive financial systems is in agenda of all policy makers in both developed and developing countries aiming to include the poorest part of the population in to the financial system. Financial inclusion is becoming more important topic in academic world, but also among regulators and policy makers. In order to emphasize the importance of financial inclusion, this paper investigates the extent of financial inclusion among Western Balkan countries and in comparison to other developing regions around the world. Using data from the World Banks’ Global Findex data base, this paper provides comparison of the level of financial inclusion in Western Balkans counties, focusing on the importance of government role in increasing financial inclusion. Research shows similar level of financial inclusion within Western Balkan countries measured by the following indicators of financial inclusion: percentage of population having formal account at a financial institution, percentage of population saving at financial institution and percentage of population borrowing at financial institution.

The basic characteristics of vacuum switches are the following: high reliability, mechanical and electric durability, easy maintenance (no requirement for replacing or refilling the media intended for arc quenching, small dimensions and weight, the current being interrupted at the first zero phase without being accompanied by the repeated arc ignition, safety in terms of explosion and fire and zero environment pollution) [1-3]. The phenomenon of electric arc occurs in the course of the switching operation circuit-breaking with current. If this operation breaks the nominal current, the electric arc is wide (the diffuse arc). In case of short-circuit current breaking, the electric arc is narrow. The wide electric arc leads to contacts conditioning and increasing the value of breakdown voltage of the switch with open contacts. The narrow concentrated electric arc leads to considerable topography change of electrode surfaces thereby decreasing the breakdown voltage value of the switch with open contacts [4-7]. The concentrated arc oscillates under the influence of electromagnetic forces along the electrodes’ edge. In modern vacuum switches, the magnetic field in intercontact space is used for quenching the electric arc. The shape of magnetic field is obtained by contact geometry. The most commonly used shape is that of radial or axial magnetic field [8-10]. The aim of this paper is to examine the influence of the magnetic field shape in the inter-contact space in the context of contact degradation during the switching operations of circuit-breaking with current. 2. SWITCHING OPERATIONS OF CIRCUITBREAKING WITH CURRENT

Several mixtures, based on urea, urea hydrogen peroxide complex (UHP), triacetone triperoxide (TATP) with some inorganic oxidants were studied by means of ballistics mortar with TNT as a reference standard. The detonation pressure, P, detonation velocity, D, detonation heat, Q, and volume of gaseous product at standard temperature and pressure conditions (STP condition) were calculated by the mean of Explo5 V6.3. The relatively high explosive strength of some samples relative to the TNT charge, focuses on the positive influence of hydrogen peroxide presence in these mixtures, with advantage in the form of its complex with urea (i.e. as UHP).
