Mine site reclamation is a relevant step in maintaining ecological balance after mining activities. Although mining activities provide many economic benefits, they often have a negative impact on the environment. These environmental problems require effective and sustainable solutions. To minimize the effects of mining, environmental management is obligated to stabilize the land, so it is productive after mine closure and leads to the best possible purpose. Regulatory authority sets out the criteria for reclamation to be accomplished by the mine reclamation program such as compliance, land re-contouring, revegetation, and final completion.

Background: The incidence of HF following ACS remains unacceptably high at discharge and several identified risk factors contribute to the development of HF in this context. Objective: This study investigated the prevalence and clinical significance of HF in patients admitted to the Clinic for Heart, Blood Vessels, and Rheumatic Diseases at the Clinical Center of the University of Sarajevo following ACS. Methods: This retrospective observational study was conducted at the Clinic for Heart, Blood Vessels, and Rheumatic Diseases of the Clinical Center of the University of Sarajevo between February 1st and April 1st, 2023, involving patients who were admitted because of ACS. Results: Patients with HFrEF were significantly (p=0.034) older (70.0 (62.0;76.0) vs 67.0 (57.5;75.0)), had (p=0.046) higher median score of LDH (321.5 (222.3; 501.5) vs. 256.0 (200.0; 420.0)), fibrinogen (p=0.047) (4.5 (3.2; 5.1) vs 3.6 (2.8; 5.0)), and NT-proBNP (p<0.001) (3705.0 (2500.0; 12559.5) vs. 500.0 (275.0; 333.0)), had enlarged left atrium diameter (3.9 (3.4; 4.4) vs 3.6 (3.1; 4.1)), enlarged left ventricular diameter both in diastole (5.1 (4.5; 5.8) vs 4.6 (4.1; 5.1)) and systole (3.7 (3.2; 4.1) vs 3.5 (3.1; 3.7)), thinner interventricular septum diameter both in diastole (1.1 (1.0; 1.2) vs 1.2 (1.1; 1.3)) and systole (1.3 (1.2; 1.5) vs. 1.4 (1.3; 1.5)) and elevated right ventricular systolic pressure (37.0 (30.0; 47.5) vs. 35.0 (28.0; 40.0 )) compared to patients without HFrEF. Severe mitral regurgitation was more observed in group of patients with HFrEF (p<0.001). Conclusion: HFrEF patients showed a 40% incidence of post-ACS, had elevated LDH, fibrinogen, and NT-proBNP levels, along with distinct echocardiographic differences, including enlarged heart chambers and higher mitral regurgitation rates following ACS. Early HF risk factor management is crucial for optimizing outcomes in ACS patients.

The aim of the research was to determine the total content of cadmium (Cd) and copper (Cu) in agricultural soils and to determine the potential toxicity of different intake routes for children and adults. Two locations were selected (Tomislavgrad and Mostar) where field crops were grown. Taking soil samples and determining the content of Cd and Cu was carried out according to the Instructions on determining the permitted amounts of harmful and dangerous substances in the soil and their testing methods (Official Gazette of FBiH, no. 96/22). A health risk assessment model based on the guidelines of the US Environmental Protection Agency (USEPA, 1996; USEPA, 2002; USEPA, 2011) was used to calculate the human health risk assessment. The measured values of the total content of copper and cadmium at the Tomislavgrad location are in accordance with the prescribed limit values. The copper content at the Mostar location was 205.90 mg/kg, which is above the limit value, and the cadmium content is in accordance with the prescribed limit values. When the HI value is less than 1, then there is no risk to human health, but if the values are greater than 1, then there is concern about non-carcinogenic risks (USEPA, 2004). The USEPA considers a carcinogenic risk in the range of 1×10–6 to 1×10−4 to be acceptable to human health. Calculations for non-carcinogenic and cancerous health risks were following the limit values.

<p style="text-align: justify;">This paper deals with the numerical determination of the stress intensity factor KI for meridional cracks on the ellipsoidal head of pressure vessels. The experiment was carried out according to selected parameters, including vessel diameter, wall thickness and pressure. The analysis of the results concluded that the cylindrical segment of the ellipsoidal head and the crown of the ellipsoidal head are the most critical places for the appearance of cracks, exposed to tensile stresses. Regression analysis determined that the internal pressure has the greatest influence on the KI factor, while the diameter of the vessel is also significant for the crown of the ellipsoidal head. The conducted experiments confirm the obtained regression models, although deviations attributed to the imperfections of the numerical simulations were observed. Despite this, it is concluded that the obtained values of the KI factor are satisfactorily accurate.</p>

<p style="text-align: justify;">Fracture mechanics is a field that is increasingly studied and applied in modern industry. One of the most widely accepted methods for assessing structural integrity in this field is the SINTAP method. Although there are many literary sources available that discuss this<br />method, very few of them present its concrete application. This paper presents the application of the mentioned method, along with appropriate equations, at a basic level of analysis. The relevant fracture mechanics parameters are determined numerically using<br />Ansys software, with the example of a thick-walled pressure vessel with cracks in the support zone. The analysis takes into account the effects of operational loads, as well as residual stresses resulting from welding.</p>

The study measures and compares the levels of financial integration in Bosnia and Herzegovina and Slovenia between 2000 and 2020. This study aims to determine the impact of industrial index, gross domestic product per capita, trade openness, and corporate tax rate on the level of international financial integration. The statistical methods employed are unit root tests, OLS regression, the Breusch-Pagan test, and the heteroskedasticity test. For the 20-year time span and annual data for each parameter, the results have shown a significant positive correlation between gross domestic product per capita and financial integration for both countries. The results for Slovenia indicate that financial integration is negatively affected by trade openness and corporate tax rates, whereas gross domestic product per capita and industrial production index affect positively. In the case of Bosnia and Herzegovina, corporate tax rate and industrial production index affect financial integration negatively, while trade openness affect positively but insignificant with financial integration.

The paper analyzes the effects of medicines policy on the functional separation of pharmacy and drugstore businesses from the early 19th century to the Second World War. Attempts to maintain personal and professional interests in the delivery of medicines prompted the long-standing dispute between pharmacists and druggists over the control and trade of drugs and poisons. The issue of state control generated complex processes that emphasized the professional role of pharmacists as providers of pharmaceutical services and druggists as wholesalers of medicines.

In the dynamic realm of online gaming, sustaining player engagement and immersion within a virtual environment is paramount for both the player community and game developers. World of Warcraft (WoW), a prominent massively multiplayer online role-playing game (MMORPG), has experienced considerable evolution since its inception in 2004. As gaming technologies advance and player expectations shift, a variety of media platforms, such as forums, social networks, and streaming services, have surfaced, playing a pivotal role in augmenting the WoW gaming experience. This study delves into the impact of different versions of WoW on the players' content experience, focusing on how these media platforms influence player engagement, communication strategies, and problem-solving approaches. Employing qualitative research methods, particularly in-depth interviews, this paper weaves a comprehensive narrative that sheds light on the intersection of technological evolution and gaming experiences. Our findings indicate that the specific version of WoW plays a critical role in shaping player interactions and problem-solving methods. The Classic WoW iteration fosters a sense of community and interaction, necessitating collaboration and the use of external resources. In contrast, Modern WoW has streamlined gameplay mechanics, thereby reducing the emphasis on collaborative efforts and the role of community within the game. This research underscores the fluid nature of social dynamics within the game, evolving in response to the changing preferences and expectations of the player base.

<p>Three new neutral complexes of copper(II) containing chalcone ligands derived from 2'-hydoxyacetophenone and 4-substituted benzaldehydes were synthesized. Complexes were prepared by solution synthesis and characterized by spectroscopy. The catalytic activity of complexes was examined in the reaction of 3,5-di-tertbutylcatehcol (DTBC) oxidation. The kinetics of DTBC catalytic oxidation by copper(II) complexes (1 &ndash; 3) was investigated spectrophotometrically under pseudo-first-order conditions. Catalytic parameters, the maximum reaction rate (vmax), Michaelis-Menten constant (KM), catalytic efficiency, catalytic reaction rate constant (kcat), turnover number (TON), and turnover frequencies (TOF) for complexes 1 &ndash; 3 in DTBC oxidation were collected. The studied complexes 1 and 2 were found to have moderate catalytic activity, while complex 3 does not show catalytic properties.</p>

Observing through the historical prism of regional development and regionalization in Bosnia and Herzegovina, city and region of Sarajevo have special importance and significance. This is mainly due to the fact that the City of Sarajevo is the main administrative center, i.e. the center of political, economic, cultural and overall social life and development in Bosnia and Herzegovina. At the same time, the Sarajevo is the center of Canton of Sarajevo, the center of this macro-region, as well as it is the capital of the entity of the Federation and state of Bosnia and Herzegovina. All those facts make Sarajevo attractive both for life and business, furthermore for studying its capacity and development potentials as well. In modern economics, the regions represent an important development level, while regionalisation represent an essentional component of the political systems of the modern state. The regions have become a link between local and central (state) institutions of government and local and overall economic development of country. The Bosnia and Herzegovina has a long tradition of regionalization and regionalism. Over long time, it has gone through verious phases and forms of regionalisation depening on then chraging political order. Sarajevo as a city and the region has historicaly developed in two directions. First, towards the capital of state of Bosnia and Herzegovina and the main administrative center. Secondly, towards the center of the region, i.e. the macro-region. Sarajevo macro-region is the most developed region in Bosnia and Herzegovina in terms of overall infrastructure and resources bacause of its normative, social importance and the position of the city itself. The territory covered by the Sarajevo macro-region has significant natural resources, energy potentials, as well as resources for the development of industry. Truistically, along with Mostar, it is a most impressive destination for tourists. Nevertheless, this macroregion still does not fully exploit the resources available to it, due to the many limitations and obsticles that directly affect it and that require adequate resolution.

Translating work by authors who were forced to leave their original cultural context, which provided them with a unique position of viewing their own, but also other identities – now has a new, more interesting function. Translation thus does not only search for a common space for universal recognition and understanding based on common experiences but rather communicates differences and specific local qualities as opposed to the global context. In the English translation of the collection of stories by Miljenko Jergović, Sarajevo Marlboro, a book about the lives of common people from Sarajevo before and during the siege in the nineties, a translator is in a different relation toward the readers, due to the very need to use a translation for communication. In this process, the specification can be seen as not only a translation technique but a strategy for explicitation and explanation of Bosnian & Herzegovinian cultural elements, especially those which are invisible, under the surface of the text, coded in our cultural identities. This paper analyses the translation of cultural elements of Bosnian identity, and the techniques used in their translation.

Važan preduvjet za unaprjeđenje proizvodnje trešnje pored odabira sorte i podloge s dobrim pomološkim karakteristikama je i procjena potrebe za navodnjavanjem, kao način na koji će se ono i obavljati. U radu su prikazani rezultati dvogodišnjih poljskih pokusa (2018.-2019), s ciljem utvrđivanja utjecaja režima navodnjavanja i sorte, te njihove interakcije na prinos i masu ploda. Ispitivane su tri sorte trešnje različitih razdoblja zriobe (Burlat, Skeena, Sweet heart), cijepljene na slabo bujnu podlogu Gisela 5, uzgajane na tlu Eutrični kambisol. Rezultati su pokazali da je sorta Skeena u 2018. godini imala najveću prosječnu masu ploda (11,68 g) i prinos (9,64 kg/stablu), dok je u 2019. godini imala najmanji prosječan prinos (3,05 kg/stablu). Sorta Burlat u 2019. godini je imala najmanju prosječnu masu ploda (7,36 g). Korelacijskom analizom utvrđena je statistička značajnost režima navodnjavanja na ispitivane parametre promatranih sorti trešnje.

<p>Funkcioniranje triju službenih jezika u Bosni i Hercegovini predstavlja vrlo interesantan model pripremanja tekstova na bosanski, hrvatski i srpski jezik, te se dokumenti važni za pravni sistem na&scaron;e države objavljuju tako da svaki ima svoje tri vrlo slične <span style="text-decoration: underline;">verzije.</span> U ovom radu analiziratće se dokument s nazivom Preporuke o priznavanju specifičnih oblika učenja na bosanskome i srpskome ili Preporuke o priznavanju specifičnih vidova učenja na hrvatskome, a cilj rada jeste da se izdvoje uočene razlike među verzijama, sagleda odnos različite i jednake upotrebe određenih jezičkih pojava, te rasvijetli gramatička opravdanost prikazanih razlika.
