Abstract Generation of photovoltaic power plants is growing rapidly in the last ten years in the world. One of the key factors for the construction of floating photovoltaic power plants is to provide space for their construction. This paper presents statistical indicators of installed capacities of floating photovoltaic power plants, as well as a detailed description of the components of these power plants. Approaches to construction and maintenance recommendations are described in more detail. The basic results of simulations are presented on a concrete example of a floating photovoltaic 1 MW power plant on Lake Modrac. The available areas of artificial lakes in Bosnia and Herzegovina were analysed, and it was shown that the installation of floating photovoltaic power plants on 5% of the surface of artificial lakes would provide around 10% of the total electricity consumption in Bosnia and Herzegovina.

Cervical cancer is a significant global health concern affecting young women, with over 500,000 new cases reported annually. This questionnaire-based study aimed to evaluate the knowledge of cervical cancer prevention among female students at the University of Novi Sad during the COVID-19 pandemic using the Cervical Cancer Knowledge Prevention-64 (CCKP-64) tool. The study sample consisted of 402 predominantly 20–22-year-old female students from either social or technical science faculties in urban environments. Results revealed that out of the 402 female students involved in the study, most had a good general knowledge of primary prevention of cervical cancer, with a correct answer rate ranging from 29.9 to 80.6%. On the contrary, only 63.4% of female students have heard about the vaccine against cervical cancer; 52.0% know that the vaccine exists in Serbia; and 31.8% know where to get vaccinated. Only a small proportion of students (9.7%) have encountered cervical cancer among their relatives/friends and think that the disease could affect them in the future (25.4%). Older students (>26 years) generally (p < 0.05) had better knowledge regarding distressing symptoms of cervical cancer, cytological examination and secondary prevention; however, it was also noted that a significant percentage of this age group reported not having received vaccinations (53.0%, p = 0.001). This study underscores the need for increased awareness and education about the HPV vaccine and secondary prevention among young women in Serbia. Future research should investigate knowledge and attitudes toward cervical cancer prevention in diverse populations to develop effective interventions and strategies. These findings have implications for public health policies in Serbia to promote cervical cancer prevention among young women.

Fermentation is a crucial process in the production of alcoholic beverages such as spirits, which produces a number of volatile compounds due to the metabolic activities of yeast. These volatile compounds, together with the volatile components of the raw materials and the volatile compounds produced during the distillation and aging process, play a crucial role in determining the final flavor and aroma of spirits. In this manuscript, we provide a comprehensive overview of yeast fermentation and the volatile compounds produced during alcoholic fermentation. We will establish a link between the microbiome and volatile compounds during alcoholic fermentation and describe the various factors that influence volatile compound production, including yeast strain, temperature, pH, and nutrient availability. We will also discuss the effects of these volatile compounds on the sensory properties of spirits and describe the major aroma compounds in these alcoholic beverages.

Context: Rivaroxaban is an oral direct factor Xa inhibitor reducing the risk of systemic embolism and stroke in patients with nonvalvular atrial fibrillation. Aims: The primary objective was to evaluate the effectiveness of rivaroxaban therapy in reducing the risk of systemic embolism and stroke in patients with nonvalvular atrial fibrillation, whereas secondary objectives were to monitor therapy safety and the patients' adherence to treatment. Settings and Design: The prospective, postmarketing clinical trial was conducted on patients with nonvalvular atrial fibrillation with one or more risk factors, such as congestive heart failure, hypertension, and diabetes mellitus, who suffered a stroke or a transient ischemic attack. Subjects and Methods: At the baseline visit, the CHA2DS2 score was determined, and therapy was introduced. At three control visits (1, 3, and 6 months after baseline), systemic embolism, stroke, bruises, or bleeding occurrences were recorded. Furthemore, adverse events were monitored, and the Morisky score (MMAS-8) for treatment compliance was determined. Results were compared to previous studies. Results: The study included 471 patients. The incidence rate in events per 100 patient-years (95% confidence interval) was 2.6 (0.1–5.1) for systemic embolism and 4.3 (1.6–7.0) for stroke. The most common form of bleeding during rivaroxaban therapy was epistaxis. Adverse events were reported in 12 (2.7%) patients. Therapy adherence was in the range of medium adherence for the entire study period, with the average score decreasing significantly from the 1st to 6th months (P < 0.001). Conclusions: Rivaroxaban showed good efficacy and safety in reducing the risk of systemic embolism and stroke in patients with nonvalvular atrial fibrillation including patients with comorbidities.

Direct current (DC) power systems are gaining interest in the last decade due to increased utilization of DC outputted power sources, DC based energy storage (ES) elements and DC inputted loads. Microgrids are also becoming widely researched as the main foundation of smart grid. It is therefore logical to try to utilize DC microgrid (DCMG) concepts in organization of power systems in wide range of applications. DC microgrids have several important advantages compared to alternating current (AC) microgrids. The control system is essential in order to keep DCMG operating properly, reliable and efficient. Their control structures, with special interest in hierarchical control are explored and compared in this paper in terms of architecture and techniques. This paper presents real world applications using DCMG concept. Future research propositions given in the final chapter can be used as a foundation for researchers exploring the area.

A building-integrated microgrid (BIM) has been a widely utilized concept in low-carbon smart cities. The key advantages of microgrids are using locally available renewable energy sources (RES) and reducing dependency on fossil fuels. Solar photovoltaic (PV) systems and battery storage systems play a crucial role in BIM to achieve desired goals. Due to legal/regulatory and technical restrictions, the distribution system operator (DSO) often imposes zero energy export (ZEE) for these microgrids. Therefore, the sizing of solar-battery systems in BIM, which will be technically feasible and economically optimized, is a challenge for designers, owners and DSO. The objective of this paper is to show the practical approach for design and sizing a microgrid for public buildings using the real data sets of a power consumption and solar energy production. As an example, the BIM for the Faculty of Electrical Engineering, University of Sarajevo is presented.
