Summary This paper presents the influence of equal channel angular extrusion on the microstructure and properties of composites based on the A356.0 aluminium alloy with the addition of 6 wt.% fly ash as reinforcement. The composite was produced using the compo casting method. The microstructure of the composite was analysed using an optical microscope, computer tomography, and scanning electron microscopy. Rosettes and spheroidal particles were observed in the microstructure of the cast sample, and there was a good distribution of fly ash within the matrix. Equal channel angular extrusion was performed in three passes at the same parameters. After each pass, the microstructure was refined, and fly ash was even better mixed into the matrix. Thus, the strength and hardness of the composite increased after each pass. A fully homogeneous material was achieved after the second pass.

Akademik Mirko Pejanović u svom višegodišnjem naučnoistraživačkom radu imao je u fokusu nekoliko naučnih polja. On je pratio, izučavao i tumačio politički pluralizam u Bosni i Hercegovini, evropske i euroatlantske integracije u kontekstu Dejtonskog mirovnog sporazuma, državnost BiH u XX i XXI stoljeću, biografije istaknutih ličnosti BiH, nastavno-pedagoški i mentorski rad pojedinih doktoranata na fakultetima širom BiH, a posebno lokalnu i regionalnu samoupravu. Sve naučne oblasti koje su mu bile u fokusu i o kojima je pisao međusobno su povezane i prožimaju jedna drugu, iako na prvi pogled djeluju raznovrsno. Sve ove oblasti čine koherentnu cjelinu unutar političkih i pravnih nauka i, što je veoma važno, fokusirane su na državotvornu dinamiku BiH. Akademik Mirko Pejanović je pristupao ovim temama interdisciplinarno, spajajući politologiju, sociologiju, historiju i pravo, te javnu upravu i regionalizaciju, kako bi dao potpunije i sveobuhvatnije odgovore na ključna pitanja opstanka i razvoja BiH. Posebno mu je značajan naučni i pedagoški rad vezan za lokalnu i regionalnu samoupravu, ostvaren istraživanjima, oblikovanjem i definisanjem ovih veoma važnih oblasti ljudskog života, te doprinoseći razvoju tih oblasti ljudskog djelovanja. Njegov rad je, između ostalog, imao pozitivne posljedice, jer su ideje, istraživanja i pažljiva zaključivanja bili iskazani njegovim brojnim nastupima na konferencijama, okruglim stolovima, predavanjima, kao i napisanim člancima i knjigama, te su imali uticaj i efekte pri donošenju brojnih propisa, ali i u profiliranju politika na državnom i drugim nivoima u BiH.

Economic entities in the global market, within the oil industry, have become aware that they must pay attention to the environment in their business operations. Environmental accounting enables them to track and analyze the necessary information concerning their effects on the environment. For many economic entities, monitoring the harmful impacts on the environment and environmental protection is not only a challenge to meet the requirements of regulatory bodies and supply chains, due to the reputation of business image and consumer pressure, but also due to the necessity of a business strategy that promotes corporate sustainable development. The subject of this research is the analysis of the state of environmental accounting in the oil sector, while respecting the framework of sustainable development faced by economic entities in this sector. The aim of the paper is to investigate how much attention is devoted to environmental accounting and sustainable development in the oil industry in Bosnia and Herzegovina, and to apply the regulations that govern environmental accounting, as well as to systematize the components of environmental accounting, objectives, and dimensions of sustainable development. It has been established that the implementation of environmental accounting is weak, but that in making business decisions, economic entities in the oil sector in Bosnia and Herzegovina rely on the effects of the economic and environmental dimensions of sustainable development.

Background: Water is essential in air conditioning processes, where it is used for cooling or heating. Its longer retention in the tanks and pipes of air conditioning devices can lead to physical and chemical changes that favor the appearance and reproduction of Legionella spp. This pathogen causes diseases that arise from inhalation of contaminated aerosol. The research was conducted in the Federation of Bosnia and Herzegovina, Bosnia and Herzegovina during 2023-2024. and included 30 public facilities where 54 water samples were collected from air conditioning devices. Objective: The main goal of the research was to determine the presence of Legionella spp. in water from air conditioning devices, and to examine correlation of physical and chemical parameters (temperature, residual chlorine, ph value, iron, zinc and copper) with the pathogen presence. An additional goal of the research was to examine the relationship between the physical and chemical parameters of water. Methods: The research was conducted at the territory of the Federation of Bosnia and Herzegovina (FBiH), Bosnia and Herzegovina (BiH) in the period 2023-2024. The samples were analysed in an authorized laboratory in Sarajevo, using standard microbiological and chemical methods. The water of the air conditioning units was analysed for presence of L. spp., the detection of the bacteria and the determination of the relationship between the examined physical and chemical factors and the settlement of pathogens in the air conditioning units. Results: Legionella spp. was isolated in 7 (13%) of 54 analysed samples. A correlation between higher temperature, lower residual chlorine, and higher concentrations of iron and copper with the bacteria appearance was established. Among the analysed parameters, several significant mutually positive correlations were recorded. Out of a total of 54 analysed samples from air conditioning devices, L. spp. was isolated in seven. The results showed that there is a relation between higher temperature and lower concentration of residual chlorine, as well as higher concentrations of Fe and Cu, with the occurrence of L. spp. in air conditioning devices. No statistically significant association between the presence of bacteria and Zn concentration or water pH was confirmed. By analysing the mutual relations between the tested physical and chemical parameters, the relation of Fe with Zn and Cu, and Zn with Cu and Ph value was determined. The limitation of this study refers to the fact that during the testing the so-called dead pipes in the system was not detected nor present, nor was there a test for the presence of biofilm inside the installation. Conclusion: The results indicate the importance of regular monitoring of water parameters in air conditioning devices in order to reduce the risk of Legionella spp. colonization and to improve preventive measures in public health and air conditioning engineering.

Introduction/Objective. Introduction/Objective Following the failure of the single-wire technique in percutaneous coronary intervention (PCI) for chronic total occlusions (CTO), two principal anterograde escalation strategies are commonly employed: the parallel-wire technique and antegrade wire escalation (AWE). Despite their widespread use, comparative data on the procedural characteristics and long-term clinical outcomes of these strategies remain scarce. This study aims to compare the procedural parameters and long-term outcomes of the parallel-wire and AWE techniques after single-wire failure in CTO PCI. Methods. This retrospective, single-center study included patients who underwent successful CTO PCI between January 2018 and December 2023 using either the parallel-wire or AWE technique following single-wire failure. The primary endpoint was a composite of cardiac death, myocardial infarction, stroke, or target vessel revascularization (TVR). Secondary outcomes included procedure duration, fluoroscopy time, contrast volume, and total radiation dose. Median follow-up duration was 1222 days (IQR 580-1969 days). Results. Among 270 CTO PCI procedures, 112 (41.5%) required escalation: 90with AWE and 22 with the parallel-wire technique. Baseline clinical and angiographic characteristics were comparable. The primary composite outcome occurred in 14.4% of the parallel-wire group and 9.1% of the AWE group (p = 0.73). No significant differences were observed in individual clinical events. Procedure duration was longer (95.5 ? 43.6 vs. 77.0 ? 30.7 min; p = 0.064) and contrast volume higher (336.4 ? 113.3 vs. 271.6 ? 90.6 mL; p = 0.014) in the AWE group, with similar fluoroscopy time and radiation dose. No clinically or ?ngiographically significant complications occurred during the periprocedural period. Conclusion. Both AWE and parallel-wire techniques demonstrate comparable safety and efficacy following single-wire failure in CTO PCI. While procedural efficiency slightly favored the parallel-wire strategy, overall outcomes support either approach, pending further prospective validation.

Customer satisfaction reflects the quality of pharmaceutical services and depends on various factors, such as the quality of services, pharmacists' skills and customer' demographic characteristics. Positive experiences strengthen customer trust and loyalty. Research into user satisfaction is an important tool for improving services. The aim of the work was the analysis of user satisfaction with pharmacy services in Serbia over the last twelve years. Annual reports on user satisfaction in pharmacies from 2013 to 2024 were analyzed. Based on key indicators, a report was prepared comparing satisfaction over the years, taking into account various factors and service quality. With the exception of 2020, public, private and health center pharmacies participated every year. The highest response rate was recorded in 2015. More than 60% of users visit a pharmacy more than five times a year, usually waiting less than five minutes. The highest level of satisfaction with the availability of medicines was recorded in 2021, while overall satisfaction with services peaked in 2022. User satisfaction has remained stable, indicating good availability and quality of pharmaceutical services. The results may contribute to further improvement in practice.

Tionite is a solid residue formed during the production of titanium dioxide through the chloride process. This material is acidic and contains a high concentration of titanium, which makes it a potential secondary resource for titanium recovery. Instead of being disposed of as hazardous waste, tionite can be processed to extract valuable metals, particularly titanium. In this study, the recovery of titanium from tionite was carried out using an autoclave leaching method under high-pressure oxygen conditions. The presence of oxygen under pressure promotes the formation of titanium oxysulfate, which enhances the dissolution of titanium into solution. This approach enables selective leaching of titanium while limiting the dissolution of other unwanted elements. The leaching experiments were designed to explore optimal conditions for efficient titanium recovery, including temperature, pressure, and leaching time. The main objective of this research is to present a viable route for the valorisation of tionite by turning a hazardous acidic waste into a valuable source of titanium. This process contributes to waste reduction in the titanium dioxide industry and supports more sustainable resource management.

The college years are critical to students' health as they face various challenges, including social influences and unhealthy lifestyles. Limited access to health services in residence halls increases the risk of unhealthy behaviours. The aim of this study was to investigate students' attitudes towards public health services for primary prevention in dormitories and to make suggestions for improvement. A cross-sectional study was conducted using a questionnaire among students living in halls of residence. The survey explored students' views on healthcare and the availability of preventive services for students living away from home. A total of 996 students participated (response rate 99.1%). Most were unemployed (83.9%). The most frequent preventive visits were to dentists (34.4% twice a year, 24.7% once a year), while 37.7% never visited a gynaecologist/urologist. The majority (68.6%) stated that a pharmacy was necessary in their dormitories. Basic health services include general practitioners (82.3%) and psychologists (21.4%). Attitudes towards health centres varied significantly by place of residence (p<0.001). Primary prevention should be improved by health centres with student-friendly opening hours and additional activities that promote access to healthcare and awareness of prevention.
