SUMMARY The aim of this research was to examine the rheological parameters of carotid arteries and the frequency of abnormal values in patients with metabolic syndrome (MetS) with and without diabetes mellitus (DM). The sample consisted of 90 subjects and was divided into two equal groups. The first group consisted of patients with MetS but without DM, while the second group had both MetS and DM. We used the values of the peak systolic velocity (PSV) as a reference for pathology. The results showed pathological values of PSV in the right internal carotid artery (ICA) in twelve patients in the MetS + DM group. The study found that the incidence of pathological rheological parameters was higher in subjects with MetS + DM as compared to those with only MetS. Subjects with MetS + DM had higher values of maximum acceleration during systole in various carotid arteries. A subject with MetS + DM also showed total flow obstruction in the left and internal carotid artery (ICA) and a severe narrowing of the right ICA, indicating the presence of carotid artery disease. The study also found that nearly two-thirds of subjects with MetS + DM had pathological values of PSV in the right ICA and slightly fewer in the left ICA. Research on French populations has shown similar results. Eleven patients had pathological values in the left ICA. The frequency of the carotid rheological parameters’ abnormalities was significantly higher in the MetS with DM patient group. The frequency of abnormalities in the rheological parameters of carotid circulation was significantly higher in patients with MetS and DM (as compared to non-diabetic patients). In our study, pathological changes were generally more susceptible to ICA. This indicates the importance of screening the rheological parameters of subjects with MetS for the prevention and treatment of cerebrovascular disease.

SUMMARY The aim of this cross-sectional study was to determine the knowledge, attitudes and behavior of medical students in relation to COVID-19 according to different medical schools and duration of studies. A validated questionnaire was administered to 192 medical students at two universities in Croatia and one from Bosnia and Herzegovina. Fisher-Freeman-Halton and Kruskal-Wallis tests were used to examine differences among study groups. The association of variables was tested with a linear regression model. A negative correlation was found between adherence to measures and attitudes (ß=-0.36; p<0.001). Studying at the University of Zagreb was positively associated with students’ knowledge about COVID-19 (ß=0.24; p=0.033) but negatively with students’ attitudes (ß= 0.26; p=0.013). Compared to the last study year students, second-year students had lower knowledge (ß=-0.28; p=0.040) and statistically nonsignificant negative attitudes (ß=-0.24; p=0.055). Fifth-year students had more negative attitudes (ß=-0.24; p=0.008) compared to sixth-year students. The association between knowledge and attitudes was weak and statistically borderline nonsignificant (ß=0.14; p=0.056). The lack of association between knowledge and attitudes requires additional research to identify the potential factors that favor the formation of attitudes toward appropriate protection against COVID-19.

SUMMARY The aim of the present study was to assess mild cognitive impairment (MCI) and cardiometabolic risk factors (CMRF) in Bosnian and Herzegovinian patients with heart failure (HF). This study included 80 patients with HF and 40 healthy controls. Montreal Cognitive Assessment (MoCA) testing was used to evaluate cognitive function. Abdominal obesity was assessed by waist circumference, and hypertension was assessed by the auscultatory method. Data on other CMRF and comorbidities, such as diabetes, smoking, alcohol consumption, and atrial fibrillation (AF), were gathered with a specially designed questionnaire. Lipids, C-reactive protein (CRP), and fibrinogen were assessed with standard laboratory methods. Student, Mann-Whitney, and Chi-square tests were used to determine significant differences between groups. Associations between categorical variables and correlation coefficients were assessed by the Chi-square and Spearman test, respectively. The prevalence of MCI in patients with HF was 77.5%. We found significant associations between MCI and diabetes, hypertension, AF, and smoking in patients with HF. We found no significant associations between MCI, abdominal obesity, and alcohol consumption. A significant positive correlation between MCI and total cholesterol was observed in patients with HF. Furthermore, a lower MoCA score was associated with higher values of CRP and fibrinogen in HF patients. The present study showed a high prevalence of MCI in Bosnian and Herzegovinian HF patients as well as its association with various CMRFs. These results suggest it is necessary to begin MCI screening in HF patients, especially since data from the literature point to improvement in cognitive performance with appropriate HF and concomitant CMRF treatment.

SUMMARY This study aimed to evaluate retinal nerve fiber layer thickness in exfoliation syndrome (XFS), present unilaterally, using optical coherence tomography (OCT). This prospective study included 90 examinees with unilateral syndrome. However, examinees with higher intraocular pressure or findings implicative of glaucoma were excluded from the study, as well as examinees with optic nerve changes. In individuals with unilateral XFS, OCT findings were compared between the two groups: the affected eye group and the fellow eye group. The study results show that the average thinning of the retinal nerve fiber layer, especially in the inferior and superior quadrants, has not resulted in visual field defects in examinees with unilateral XFS. In the group of eyes without XFS, 85.55% exhibited reference inferior quadrant thickness values, and 91.11% exhibited reference superior quadrant thickness values. In the group of eyes with manifest XFS, 82.22% exhibited reference inferior quadrant thickness values, and 88.88% exhibited reference superior quadrant thickness values. Most examinees in both groups had normal average retinal nerve fiber layer (RNFL) thickness (72.22%). In examinees with clinically unilateral XFS, RNFL thinning occurs in both eyes before XFS becomes bilateral and before hypertensive intraocular pressure can be measured.

The favorable characteristics of veneer boards—plywood—enable their wide application. There is also the possibility of enhancing plywood, such as by coating it with various films, applying coatings, reinforcing it with fibers from different materials, and using improved adhesive formulas. Basalt fibers, as a natural and environmentally friendly material, are used in various forms with quite good characteristics. Results from various tests conducted in recent years indicate an improvement in the mechanical properties of composite boards, including plywood reinforced with fibers like basalt fibers. These tests were focused on determining the position and contribution of basalt fibers in the board’s structure, as well as the application of certain environmentally friendly adhesives. For this study, samples of composite material based on wood, specifically plywood reinforced with a basalt mesh, were prepared. The basalt mesh was placed within the plywood structure in various combinations of position and amount. Subsequently, a three-point bending strength test was conducted to determine the impact of the basalt mesh on the strength of the plywood. The increase in strength opens up possibilities for expanded use, material savings, and a reduction in the overall weight of the structure, which is crucial in certain applications of such boards.

Languages do not operate in isolation; rather, they evolve in continuous contact with other languages. This contact and resultant lexical borrowing can lead to minor or substantial changes in the vocabulary of the recipient language. This quantitative study aims to analyze how bor-rowing from the English language affects the formation of new verbs in the Bosnian language (verbal Anglicisms) and which suffixes in the Bosnian language (between -ova-, -a-, -ira-) are most often used to form new verbs. Additionally, the aim is to explore the frequency of use and the level of knowledge of the meaning of verbal Anglicisms. The study was conducted on 345 participants, i.e. both male and female high school students from Bosnia Herzegovina. The results indicate that verbal Anglicisms with the suffix -a- are the most often used group of verbal Anglicisms and that this preference is a result of the nature and origin of those Angli-cisms (mostly IT-related) and is not related to the linguistic nature of the Bosnian language. Furthermore, it was shown that knowledge of the original form of verbal Anglicisms affects the level of their use, and that level of use of these Anglicisms is influenced by the EL GPA and medium of instruction of the respondents, while gender, grade level, and experience of travel-ing to English-speaking countries are not significant factors in the extent of usage of these An-glicisms. Further investigation is proposed to broaden the scope of the present research in different settings and among various study groups. Keywords: Anglicisms; borrowing; language; high school students; verb.

SUMMARY Our study aimed to analyze the correlation of cancer-related parameters with tumor regression grade (TRG) and disease-free survival (DFS) by gender in 192 rectal cancer patients operated on after neoadjuvant long-course chemoradiotherapy (LCCRT). Preoperative diagnostics revealed no significant gender differences in any clinical parameters other than obesity (p=0.031). We found that slightly overweight men had a lower incidence of distant metastases (p=0.042). The post-LCCRT pathologic finding showed that women had more positive lymph nodes (ypN, p=0.002) while no other pathologic parameter differed significantly between the genders. Overall, a poor response to therapy correlated with a shorter time to disease progression (p=0.002). Women achieved ypN0 in 50% of cases, but only 27% had a good TRG compared to 40.5% of men (p=0.073). Women had a worse DFS than men, even when complete response to therapy was achieved (p=0.003), and greater depth of residual tumor invasion (ypT, p=0.035) and higher ypN (p=0.002) correlated with shorter DFS. Positive resection margins (p<0.001), higher ypN stage (p=0.003), and poor TRG (p=0.025) correlated with shorter DFS in men. We conclude that women have a poorer response to LCCRT with the possibility that therapeutic approach to the neoadjuvant treatment of rectal cancer may be gender-specific.

Hydropower is the world's most exploited renewable energy source. It provides a substantial, flexible, and reliable source of renewable energy, complementing other renewables like solar and wind power. Besides conventional hydropower potentials and technologies, the development of technologies for the exploitation of hidden hydropower potentials is an ongoing process. This paper presents the current state of hidden hydropower technologies and links them with possible applications in different hydropower potentials. Technologies and potential applications are structured within three main groups (pressurized systems, hydro storage, unpressurized systems), with their mutual interconnections analysed and displayed throughout the paper. The opportunity for the application of hidden hydropower technologies in different roles within the energy system is recognized through the concepts of off- and on-grid roles, the prosumer concept, and on-site measurement powering. This paper shows that hidden hydropower technologies could emerge as significant contributors to a smoother energy transition, especially with the prosumer and off-grid concepts.

Floating Modular Energy Islands (FMEIs) are modularized, interconnected floating structures that function together to produce, store, possibly convert and transport renewable energy. Recent technological advancements in the offshore energy sector indicate that the concept of floating offshore energy islands has the potential to become more cost-effective and more widespread than previously anticipated. This review is specifically meant as a basis for the development of new approaches to the sustainable exploitation of multi-energy sources in the offshore environment leveraging the know-how of existing technologies and, at the same time, exploring new solutions for the specific challenges of FMEIs. The paper critically analyzes the current state of data-driven approaches and structural health monitoring techniques in the offshore energy sector. It also covers topics such as met-ocean data, loads estimation, platform dynamics, coupling actions, nonlinear dynamics of mooring lines, modelling considerations, and control of electrical subsystems. It is believed that this systematic and multidisciplinary review will facilitate synergies and further enhance research and development of offshore renewable energies.

Currently, there is significant effort worldwide in the research and development of <inline-formula><tex-math notation="LaTeX">$\mathrm{{SF}}_{6}$</tex-math></inline-formula>-free high-voltage circuit breakers, both in academia and industry. One of the most important switching capabilities is thermal current interruption, a process that, in modern self-blast breakers, strongly depends on the coupled effects of nozzle geometry, nozzle ablation, backheating, pressure build-up and gas outflow, as well as contact and puffer cylinder motion actuated through the drive. Previously published investigations on the thermal interruption performance of novel switching gases have used such designs, however, due to the many coupled processes, it is not possible to control the interruption conditions in order to make a full and comparative evaluation of different <inline-formula><tex-math notation="LaTeX">$\mathrm{{SF}}_{6}$</tex-math></inline-formula> alternative gas mixtures. The aim of the present contribution is to present an experimental circuit breaker tailored for use in basic experiments that allow for an unbiased comparison of properties of alternative gas mixtures relevant for current interruption. The breaker is based on a novel puffer design with an overpressure relief valve that allows the contact stroke and blow pressure to be predicted, controlled and adjusted over a wide parameter range at current zero. This contribution lists the requirements for such an experimental circuit breaker and focuses on its design realization. Experimental validation is given that this device can be used in benchmarking the interruption characteristics of <inline-formula><tex-math notation="LaTeX">$\mathrm{{SF}}_{6}$</tex-math></inline-formula> alternatives. Systematic comparison of the thermal interruption performance of <inline-formula><tex-math notation="LaTeX">$\mathrm{{SF}}_{6}$</tex-math></inline-formula> alternatives and investigations of the processes around current zero will be reported in other publications.

The aim of this research was to examine whether there is a statistically significant relationship between shoulder flexibility, anthropometric characteristics and swimming speed short distance in kinesiology students. The study included 16 participants 22 years old, male and female with an average body weight 77.7±16,42 kg and 179±9 cm. All students included in the research attended swimming class in the third semester at the Faculty of Kinesiology University of Sarajevo. The study was applied to 5 measuring instruments: measuring instruments for the assessment of flexibility (2); Measuring instruments for the evaluation of morphological characteristics (2); Measuring instrument for the assessments of swimming speed (1). Spearman's correlation coefficient was used to determine the level of interconnection for assessing the relationship between two variables. Data collection for shoulder flexibility was measured using a shoulder elevation test, and stick rotation test, while swimming speed was measured with a digital stopwatch. The analysis of the results did not demonstrate a single significant feature that would allow the confirmation of the assumptions about the significant relations between flexibility and performance in swimming.

The beneficial effect of thermomineral (sulfur) water in the treatment of degenerative rheumatic diseases of the peripheral joints is the result of the incorporation of sulfur in the form of sulfates and sulfides into the cartilaginous parts of the joints. The aim research is to examine the therapeutic effects of thermomineral-sulfur water from Ilidza-Sarajevo using the iontophoresis method in osteoarthritis of the knee and compare it with the effects of the classic galvanization method. The study was observational, prospective, included 100 participants with osteoartritis of the knee, 50 in the Iontophoresis group with sulfur water (ISW) and 50 in the group where the Classic galvanization method (CG) was applied, both genders, aged between 31 and 80. The research was conducted in two Centers for Physical medicine and rehabilitation in Sarajevo Canton. The research results show that there is a statistically significant difference in the reduction of pain in patients after 10 days of therapy, using the ISW method 33%, with the CG method it is 24% (p< 0.05). After 15 days of treatment using the ISW method 57%, according to the CG method 45% (p<0.05). The increase in the range of mobility of the knee joint with the ISW method after 10 days of treatment is 13%, and with CG 10% (p=0.336). Results after 15 days of therapy with the ISW method 22%, and with CG treatment 16% (p=0.074). The use of Ilidza sulfuric water using the iontophoresis method in osteoarthritis of the knee improves the establishment of the functional ability of the knee joint.

The incorporation of waste glass as a component in clinker production presents a sustainable approach to addressing critical challenges in the cement industry, including the reduction of CO2 emissions and effective waste management. Waste glass, characterized by its high silica content and alkali properties, can serve as an alternative alkali source in clinker manufacturing, replacing traditional raw materials and regulating the alkali-sulphur ratio. This dual functionality not only optimizes the chemical balance in the kiln process but also enhances clinker quality by controlling phase formation. The utilization of waste materials in industrial processes is increasingly significant in promoting circular economy principles. Integrating waste glass reduces the dependence on natural raw materials such as limestone and clay, which are associated with high energy and CO2 emission intensities during production. Furthermore, waste glass contributes to a reduction in the carbon footprint of cement production by facilitating lower-temperature clinkering, thus cutting energy consumption and greenhouse gas emissions. This study highlights the potential of waste glass as a viable alternative in clinker production, emphasizing its importance in achieving sustainability goals. Beyond the environmental benefits, adopting waste materials in industrial applications contributes to waste diversion from landfills, resource conservation, and cost efficiencies, aligning with global efforts to mitigate climate change and promote sustainable development.
