In order to achieve economic progress in less developed countries, it is necessary to provide the necessary resources. Foreign investments very often represent the primary source of financing for certain world economies, and the struggle for financial resources, which are limited, is becoming greater. Many countries have a planned approach to this process, and make huge efforts to attract foreign investors. For this reason, it is necessary to systematically approach this research problem, and to create adequate strategies for attracting foreign investments. When it comes to Bosnia and Herzegovina and the surrounding countries, the competition to attract foreign investments between them is getting tougher. Each of the neighboring countries has its own competitive advantages, and with an adequate set of incentive measures, it can achieve a significant inflow of foreign investments. Unfortunately, of all the surrounding countries, Bosnia and Herzegovina has the lowest inflow of foreign investments, so it is necessary to define the competitive advantages of the business environment in Bosnia and Herzegovina.

Ovaj rad prikazuje tematiziranje ustaškog i četničkog pokreta u časopisu “Bosanski pogledi” u periodu od 1960. do 1967. godine. Časopis, čiji je glavni urednik bio Adil Zulfikarpašić, pruža značajan izvor informacija za proučavanje historijskih, socioloških i političkih aspekata. Kroz analizu različitih članaka autori istražuju percepciju i kritiku ustaškog i četničkog pokreta u Bosni i Hercegovini. Rad se fokusira na različite aspekte, uključujući ulogu Muslimana i njihovu saradnju s različitim pokretima, sukobe s drugim narodima i političke sukobe koji su prikazani unutar časopisa. Prikazuju se različiti stavovi i argumenti koje časopis donosi o ovim pokretima, ističući njihovu ulogu u Drugom svjetskom ratu i posljedice njihovih akcija. Kroz ovu analizu rad nastoji osvijetliti složenost i kontroverze povezane s temom, doprinoseći boljem razumijevanju balkanske historije i savremenih političkih odnosa.

This paper, based on the documentation from the database of the International Criminal Tribunal for the former Yugoslavia (ICTY), is dedicated to the suffering of the "Banja Luka babies", one of the many cases of tragic childhood during the aggression against Bosnia and Herzegovina in 1992. The case of the agony of new-borns in the Banja Luka Clinical-Medical Centre (CMC) caused controversy in the public. It is the subject of propaganda speculations and various political calculations that do not stop even with the act of presenting the medical documentation of the deceased newborns as exhibits for the defence during the trial of Radoslav Brđanin before the ICTY. Brđanin was found guilty and at the end of the trial sentenced to 30 years in prison for crimes against humanity, violations of laws and customs of war, and serious violations of the 1949 Geneva Conventions.

Introduction/purpose: Motor vehicles are complex dynamic systems due to spatial displacements, changes in the characteristics of components during their lifetime, a large number of influences and disturbances, the appearance of backlash, friction, hysteresis, etc. The aforementioned dynamic phenomena, especially vibrations, cause driver and passenger fatigue, reduce the lifetime of the vehicle and its systems, etc. Methods: In general, the movement of vehicles is carried out on uneven roads and curvilinear paths in the road. Not only do oscillatory movements cause material fatigue of vehicle parts, but they also have a negative effect on people's health. That is why special attention must be paid to the coordination of the mutual movement of the subsystems, and in particular, the vehicle suspension system, even at the stage of the motor vehicle design. For these purposes, theoretical, experimental or combined methods can be used. Therefore, it is very useful to have the experimental results of the oscillations of the vehicle subsystem in operating conditions, so the aim of this work was to use the movement of the 4x4 drive FAP 1118 vehicle in operating conditions (due to higher speeds - in road conditions) to define the conditions for testing oscillatory loads in laboratory conditions. Results: This is made possible by registering and identifying statistical parameters of registered quantities. Conclusion: Based on the measured data, the research can be programmed on shakers in laboratory conditions, and, at the same time, the size to be reproduced can be chosen as well.

Introduction/purpose: The hydraulic buffering valve has the greatest influence on the dynamic characteristics of power-shift transmission. The hydraulic buffering valve is a transmission element that controls increase in pressure in friction assemblies during the gear shifting process. By choosing the optimal control of pressure increase during shifting, reduction of dynamic loads in gear transmissions and thermal loads in friction assemblies is achieved. Methods: The paper analyzes the principle of one of hydraulic buffering valve solutions as well as the influence of certain parameters on the control of pressure increase. After the analysis of the working principle of the hydraulic buffering valve, a simulation model was developed in the MATLAB/Simulink software package. Results: The results obtained using the simulation model were compared with the experimental results of the selected pressure modulator solution. The selected hydraulic buffering valve was developed as part of the development of a device for power-shift transmission. The simulation results showed a satisfactory match with the experimental results. Conclusion: The developed simulation model enables a relatively easy and quick change of the parameters of the hydraulic buffering valve as well as a possibility of a faster and better understanding of the influence of individual parameters on pressure increase during the gear shifting process.

Background: The scientific researchers have the role of interacting through published articles in scientific journals or presentations at scientific and professional conferences were they can affect the practices that can make achievements to society and country. or worldwide. For this reason, scientists are encouraged after completing the project and finalizing their research investigation to publish scientific work outcomes in professional and scientific journals. Objective: The aim of this article was to describe scientometric and bibliometric indexes and explaine its importance for its evaluation and measuring quality assessment of published papers in scientific journals deposited in scientific indexed databases. Also, author criticaly analized advantages and disadvantages of current bibliometric portals for creating the list of universities and its accademic staff by counts of deposited articles in databases and number of its citations. Methods: The author searched the most influential online databases and analyzed deposited papers by scientometric/bibliometric indexes, and used a descriptive method to review important facts about scientometrics experiences in scientific and academic practice. The author used facts deposited on the main international portals for analyzing number of citations of deposited scientific papers on Scopus and Google Scholar platform - h-Index and i10-Index and number of citations as basic data fot created top list of most citated scientists in almost of all countries in the world. . Results and Discussion: Bibliometric methods are used for quantitative analysis of written materials. Citation provides guidelines for scientific work because it stimulates scientists to deal with the most current research areas and organizes scientific articles at the world level or shapes and directs them. Citation is influenced by: article quality, understanding of the article, language in which the article is written, loyalty to a group of researchers, article type, etc. Some indicators used in evaluating scientific work are Impact factor (IF); Citation of the article; Journal citations; Number and order of authors, etc. The index factor of influence depends on the quality of the journal, the language in which it was printed, the area it covers, and the journal distribution system. Finaly, three portals and its plaforms (Webometrics, "AD Scientific Index" and Stanford Bibliometric List) are not fully relevant for measuring quality assessment of universities and its academic staff, even as potentialy members of academies of sciences, like it used in the past. They need to improve in the future. In this article, we pointed out that h-Index and Google Scholar indexes for present valuable measures to determine scientific excellence. These criteria should be necessary for quality assessment of the scientific curriculum of scientists and their published papers in journals when experts of indexed databases like Medline, PMC, Scopus, etc., do reviews during the evaluation of applied journals for potentially including indexed databases. Conclusion: Current academies and academicians can propose criteria how improve indexing scientific papers with the consultation of scientific bodies and experts at universities in one country, selected regions, or worldwide. Only quality research with exact results offers the scientific community new information about the examined problem and the researcher’s personal satisfaction, and opening opportunities to receive critical reviews of those who have insight into the research.

Energy has an effective role in economic growth and development of societies. This paper is studying the impact of climate factors on performance of solar power plant using machine learning techniques for underlying relationship among factors that impact solar energy production and for forecasting monthly energy production. In this context this work provides two machine learning methods: Artificial Neural Network (ANN) for forecasting energy production and Decision Tree (DC) useful in understanding the relationships in energy production data. Both structures have horizontal irradiation, sunlight duration, average monthly air temperature, average maximal air temperature, average minimal air temperature and average monthly wind speed as inputs parameters and the energy production as output. Results have shown that used machine learning models perform effectively, ANN predicted the energy production of the PV power plant with a correlation coefficient (R) higher than 0.97. The results can help stakeholders in determining energy policy planning in order to overcome uncertainties associated with renewable energy resources.

It is known that the temperature of crystallization during the synthesis of zeolite is one of the most important process parameters. However, during the research work on the synthesis of zeolite 13X and the introduction of this material into regular industrial production, it was noticed that the heating rate of the starting reaction suspension can have an equally important influence. This influence can be so pronounced that a difference of just a few minutes in reaching the crystallization temperature can make a significant difference in product quality, affect the presence of other phases in the crystal, or even determine the direction of zeolite crystallization. Therefore, the aim of this work was to show the influence of the heating rate on the quality of the obtained 13X zeolite powders. The obtained samples were analysed in terms of crystallinity (by X-ray diffraction), chemical composition, granulometry and specific surface area (by Brunauer-Emmett-Teller analysis), and regarding water and CO2 adsorption capacities. Additionally, scanning electron microscopy analysis of the samples showed the morphological characteristics of different 13X zeolite powders. The analysis results of the obtained powders confirmed the influence of the heating rate and helped to define the optimal synthesis parameters i.e. the initial temperature and heating time, that resulted in stable product quality.
