In this study, the physicochemical, nutritional, and bioactive properties of a total of 11 commercial sumac sour samples coded from SS-1 to SS-11 were evaluated. The Brix values ranged from 61.8 to 78.6%, indicating high soluble solids and a viscous consistency. pH values varied between 1.23 and 3.05, confirming the acidic character of the products, which contributes to microbial stability. Viscosity, water activity, and electrical conductivity showed wide variability among samples, reflecting differences in raw materials and processing. Sugar profiling revealed significant variation in fructose, glucose, maltose, and sucrose contents, with some samples containing added sugars, while others maintained natural sugar composition. Ash content and protein levels were generally low, except for SS-11, which exhibited notably high mineral and protein values. Antioxidant analyses demonstrated that phenolic and flavonoid contents were highly variable, with SS-11 showing the strongest activity. Preservatives such as sorbic and benzoic acids were detected in some samples, while artificial sweeteners (Acesulfame-K, Aspartame, and Sucralose) were present in specific products. Overall, the study highlights considerable variability in the composition and quality of commercial sumac sour, influenced by raw material, processing, and potential additives. These findings underscore the importance of quality control to ensure both nutritional value and consumer safety.

Inflammation-driven mechanisms play a central role in adverse outcomes after non-ST-elevation myocardial infarction (NSTEMI), yet simple, widely available biomarkers for early risk stratification remain insufficiently defined. Hemogram-derived indices and iron-related inflammatory markers may provide complementary prognostic information. To evaluate the prognostic significance of the mean platelet volume-to-monocyte ratio (MMR) and serum ferritin in predicting major adverse cardiovascular events (MACE) in patients with NSTEMI, and to assess the association of angiotensin-converting enzyme (ACE) inhibitor therapy with clinical outcomes. This prospective cohort study included 170 consecutive NSTEMI patients admitted to the University Clinical Center Tuzla between February 2022 and January 2023. All patients received dual antiplatelet therapy and high-intensity statins. The baseline evaluation included a complete blood count, serum ferritin, and C-reactive protein. MMR was calculated as the ratio of mean platelet volume to absolute monocyte count. Patients were followed for 12 months for the occurrence of MACE, defined as cardiovascular death, non-fatal myocardial infarction, urgent revascularization, stroke, or hospitalization for heart failure. During follow-up, 103 patients (60.6%) experienced MACE. Admission MMR (18.1 ± 11.7 vs 13.2 ± 5.5; P = 0.003) and ferritin levels (284 ± 396 vs 152 ± 109 µg/L; P = 0.001) were significantly higher in patients with events. In multivariable analysis, both MMR (odds ratio [OR] 1.06, 95% confidence interval [CI] 1.02-1.11; P = 0.008) and ferritin (OR 1.28 per 100 µg/L, 95% CI 1.10-1.55; P = 0.003) independently predicted MACE, while ACE inhibitor therapy was associated with a lower risk (OR 0.24, 95% CI 0.08-0.70; P = 0.01). The combined model demonstrated good discriminative performance (AUC 0.72; 95% CI 0.64-0.80). Elevated admission MMR and ferritin were independently associated with a higher 1-year risk of MACE in patients with NSTEMI. ACE inhibitor therapy was associated with improved outcomes, although causality cannot be inferred. These findings suggest that readily available inflammatory biomarkers may complement established clinical parameters for early risk stratification and support continued guideline-directed pharmacotherapy in NSTEMI.

Abstract The legal standard of the best interest of the child is determined and quantified in various ways throughout legal proceedings. To ensure that any decision genuinely reflects this standard, it is essential to uphold the child’s right to participate fully in matters that affect them. Full participation means enabling children to express their views and participate in matters that affect them, especially in divorce cases, which often have a strong impact and consequences on their lives. Empowering children in this way not only ensures their voices are heard but also strengthens their sense of independence and dignity. The article presents the results of the research approved by the Ministry of Education and Science of Bosnia and Herzegovina Federation conducted in Bosnia and Herzegovina on the extent to which the child’s right to express an opinion is respected in divorce proceedings. The main objective of this article is to analyse whether courts in Bosnia and Herzegovina uphold this right, whether there is an age threshold for considering a child’s opinion, and how that opinion is factored into determining the child’s best interests. The key question is whether court rulings in divorce cases explicitly justify decisions about the child’s best interests in relation to the child’s expressed view.

Thanks to the exceptional natural characteristics and great biological diversity, the waters of Bosnia and Herzegovina possess significant ichthyofaunal value. Significant hydrological interventions at the biological and economic level have had a strong negative impact on the fish world, which primarily refers to the introduction of foreign (allochthonous) species. Bosnia and Herzegovina currently does not have a list of foreign or invasive species registered on its territory. The research was conducted through the analysis of scientific papers, professional literature, articles, studies, and books, with the aim of providing an overview of the diversity and representation of foreign and invasive fish species in the Adriatic and Black Sea basins. The data show a significant occurrence of introduced species, some of which have a considerable harmful impact, while others do not pose a threat to native populations. The most pronounced negative impact on native populations is caused by the species Pseudorasbora parva, Lepomis gibbosus, Sander lucioperca, Ameiurus nebulosus, Oncorhynchus mykiss, and Carassius gibelio, which have multiplied significantly. Therefore, in the future, the implementation of activities related to fish stocking and the translocation of fish stocks should be carried out under the supervision of qualified experts in the fields of ichthyology and aquatic ecosystem management.

Existing literature indicates that prolonged insertion time is associated with procedural complexity and may influence adenoma detection. Xu et al recently reported that longer insertion time correlates with lower adenoma detection, but this effect can be mitigated by sufficient withdrawal duration. Insertion time should not be regarded merely as a numeric variable but rather as a multidimensional marker of technical difficulty. Integrating the insertion-to-withdrawal ratio with composite indicators such as looping or bowel preparation quality may enhance predictive models of colonoscopy performance. Conceptualizing insertion time in this way provides a more nuanced understanding of its role in adenoma detection and highlights the need for improved frameworks that link procedural complexity with quality outcomes.

Collision detection and avoidance are crucial for safe and efficient robotic manipulation.This paper presents an affordable collision detection system for a 3Dprinted robotic arm using a Kinect camera integrated with the Robot Operating System (ROS).The proposed approach enables real-time environment perception and collision-free trajectory generation.Experimental results show a significant improvement in collision avoidance efficiency, achieving a 40% reduction in path length while maintaining real-time performance.The computational overhead introduced by collision detection is minimal, with a 12 ms delay per frame, which can be optimized further.It is demonstrating the system's ability to effectively handle dynamic environments, such as human obstacles.This work highlights the potential of low-cost 3D sensing solutions for robotics applications, making them more accessible and scalable.

Abstract This article describes a study of One Nation/One Project, a national post-pandemic arts-and-public-health initiative in the US. This values-based, convergent mixed-methods study found significant associations between arts participation, social cohesion, and well-being and offers a theory of change that illustrates these associations, as well as how arts participation increased social cohesion and enhanced well-being. At a moment when the severities of social divisions and loneliness are increasing in the US, this theory of change may enhance socia cohesion and well-being by encouraging cross-sector collaboration between the arts, public health, and municipal sectors and supporting investment in the arts.

Abstract In this paper, the drainage of storm water from traffic roads is analysed by analysing the traditional method of drainage using a separate sewage system, and also by analysing the integral approach to the drainage of rainwater in the urban area. The research objectives for the treatment of the topic in this paper are set and processed for the needs of planning and development of the sewage system for the drainage of rainwater from roads in urban areas, as well as for the evaluation and ranking of conceptual solutions and the elaboration of plans for the general solution for the collection and drainage of surface water from roads. For relevant rain episodes, i.e. rainfall of appropriate duration and intensity, runoff coefficients and flows were considered and analysed according to the rational method, all for the purpose of obtaining data on the amount of rainwater entering the sewage system. According to the set research program, it was necessary to work on defining and establishing the amount of precipitation for the area that was the research polygon, and based on exact measurement data, the optimal transverse and longitudinal drops of the level of the road were determined in order to drain rainwater from the roads as efficiently and quickly as possible, within the framework of the rules that define this area.
