    MODIFIED PETRURGICAL MATERIALS BASED ON SEDIMENTARY ROCKS USED FOR BALLISTIC PURPOSES

    Security & Future, Vol. 3 (2019), Issue 4, pg(s) 182-184

    Bulgaria has a variety of deposits (mainly in northeastern Bulgaria) of sedimentary rocks (marls) suitable for the development of compounding formulations and technology for the production of stone products. On the basis of some of these sedimentary rocks (marls), experimental technologies for innovative formulations with modifiers for usable petrurgical materials are developed and tested. The first prototypes of ballistic protection products are obtained, with physic-mechanical properties better than those when only natural sedimentary rock is used, and lighter and cheaper than in the case of corundum and silicon carbide.
    The properties of these materials allow for certain alternative applications such as the ballistic protection of ground-based mobile and stationary objects. They also make possible the production of quality articles with protective properties against high-speed kinetic effects, but at significantly lower cost than when traditional materials are used.

    LEGAL FRAMEWORK FOR THE PROTECTION OF CBRN AGENTS IN BOSNIA AND HERZEGOVINA

    Science. Business. Society., Vol. 1 (2016), Issue 4, pg(s) 33-36

    In this paper the authors present legal framework for the protection against CBRN agents in Bosnia and Herzegovina. By critical analyzing existing legal framework the authors will determine plausible legal course of action in cases of danger caused by CBRN agents. Namely, although use of CBRN agents for industrial purposes is thoroughly regulated the may be abused in the various activities against civil society. The may be abused through the acts of terrorism and sabotage and misused through inadequate handling of the agents and their byproducts. The final goal of this paper is to examine the applicable value of the existing legislation in this area in Bosnia and Herzegovina.

  • IMPORTANCE OF TRAFFIC SAFETY AND ENVIRONMENTAL PROTECTION IN SERBIA

    Machines. Technologies. Materials., Vol. 9 (2015), Issue 10, pg(s) 3-5

    This paper is devoted to traffic safety and environmental protection in Serbia. Unfortunately the level of air pollution i.e. the level of emission of carbon dioxide in the world is still raising. Additional actions are needed in order to limit the effect of climate changes in the following years. People ask why electric vehicles aren’t main-stream? It seems that price has a lot to do with it. The Road Traffic Safety Agency with its systematic and responsible activities set clear guidelines for the monitoring and improvement of road safety in Serbia. In the Republic of Serbia from 1981 till 2013 in the traffic accidents 41.718 persons were killed. In the same period 632.936 persons were seriously injured. Republic of Serbia on the 16th of November 2011 began to commemorate the World’s Day of memory on victims in the traffic accidents. Law on road traffic safety came into effect in the Republic of Serbia in 2009. and brought many changes in our legal order. Majority of those changes meant harmonization with European Union regulation in the area of traffic safety. Changes made by the st new Law on infractions (“Officaial Gazette of the Republic of Serbia“, no. 65/13) in application from March the 1 2014. show the increase of penalties for unscrupulous drivers, but drivers complain on to many regulations and difficulties to get documents for motor vehicle use. In this paper there are mentioned the most efficient hybrids we can buy today. In Serbia “FIAT automobiles of Serbia” is still the leading exporter on the list of 15 biggest Serbian exporters, according to the data of the Serbian Ministry of Finances. In April 2015 at New York Auto Show will be possible to see all new accomplishments in auto-moto industry all over the world.

  • INTEGRATED TECHNOLOGY AND MULTIMODULE TRACKED VEHICLES UNIT FOR WETLANDS PROTECTION

    Machines. Technologies. Materials., Vol. 8 (2014), Issue 8, pg(s) 47-50

    Integrated technology and new generation of multimodule tracked vehicles unit was designed by PIMR- Industrial Institute of Agricultural Engineering in Poznan within the research project WND-POIG.01.03.01-00-164/09. The Tracked Vehicles Unit (TVU) was built as a part of cooperation with Polish firm Hydromega. TVU is dedicated to work on wetlands and should have positive impact on ecology and better environment protection thanks to use of biodegradable oils and lubricants, diesel engine with Stage III emission standard, innovative tracks which have different internal and external speeds during turns. A single-phase technology is designed for harvesting/collecting and transporting biomass (reeds, grass, bushes, small trees) on wetlands, especially these that are located in National Parks and Nature 2000 areas. The TVU is designed to work with different tool modules for cutting, shredding and transporting collected biomass on wetlands. Amphibian type of the TVU’s hulls allows for work in inlands water (rivers, lakes, canals).

  • NEW TRENDS IN TRAFFIC SAFETY

    Machines. Technologies. Materials., Vol. 8 (2014), Issue 2, pg(s) 48-50

    In this paper the important events in the auto industry all over the world, situation with automobile industry in Serbia, the concern for safety of drivers and other participants in traffic, with special stress on the protection of children in traffic, as well as the obligation of environmental protection are presented. Unfortunately, mortality in traffic is becoming epidemic. The interactive map showing the basic parameters of traffic safety in all countries in the world has been started. Every year on the roads throughout the world even 1.240.000 persons are killed. On the roads in Serbia the most frequent causes of traffic accident with serious consequences are: speeding, driving under the influence of alcohol and not fastening seat belts. Children in traffic are killed mostly as passengers. Reasearch shows that Serbia is positioned very low comparing to European Union countries when it comes to the safe transport of children in vehicles and the use of seat belts. Agency for Traffic Safety in the Republic of Serbia in December 2013 celebrated 4 years from foundation and on that occasion the importance and necessity of connecting and coordination in work of all subjects competent for the field of safety was emphasized.

  • MECHATRONIC CONTROL SYSTEM IN A TILLING-AND-SOWING COMBINED MACHINE

    Mechanization in agriculture & Conserving of the resources, Vol. 60 (2014), Issue 5, pg(s) 22-24

    The article concern to the scientific and research works related to the development of mechatronic control system of sowing unit in the tilling-and-sowing combined machine. The essence of the project is the use in the combined machine of innovative control system responsible for the seeding process. The system will control the work of seeding unit (drive) and will maintain a predetermined depth of seeds sowing.

    Grooved or pinned units used in seeding are characterized by variability in application rate as a function of the changing conditions of work (e.g. on the slopes). In the proposed solution, on the basis of the identification of the sensitivity of the sowing machine on the changing conditions of work, the control algorithm will be developed, which after application to a controllable propulsion system equipped with the necessary sensors will eliminate inaccurate dosing. Project/Grant No K2/IN2/64/182979 is co-financed from the budget allocated for science.
