The growing need to reduce the negative impact on the environment and human health, as well as to meet the growing demand for eco-friendly textiles, has led to the development of environmentally friendly printing techniques and the use of natural dyes in the textile industry. Grape pomace is important waste material in winemaking, and has been extensively studied for its potential as a source of compounds with biological properties, especially anthocyanins, pigments responsible for the red, purple, and blue colors in grapes. The aim of this paper was to examine the potential use of natural dye extracted from grape pomace of domestic cultivar crna Mirisavka (GPCM) in preparation of printing paste with alginate, citric acid, and tannic acid for printing on cotton fabric. Special focus was placed to achieve process color magenta, by adjusting the pH value of the extract obtained. The natural dye from GPCM was extracted using maceration with 80% methanol, followed by sonication to enhance the yield of bioactive compounds. GPCM extract demonstrated significant antioxidant activity measured by FRAP, DPPH, and ABTS+ tests, and moderate antibacterial activity against Staphylococcus aureus and Escherichia coli. The pH-dependent stability of anthocyanins in GPCM extract was examined, demonstrating a magenta tone at acidic pH (pH 2-4) and color degradation at higher pH values. Cotton fabric printed with two different concentrations of GPCM extract (100 mg/L and 50 mg/L) showed good antioxidant and antibacterial activity. Based on the obtained results, it can be concluded that GPCM extract can be an environmentally friendly solution for the development of antibacterial and antioxidant textiles, with potential application in the production of protective clothing in healthcare institutions, as well as for the production of decorative home textiles, for the production of children's toys and textiles for packaging.
Introduction: The mechanisms of pulmonary embolism in patients with metabolic syndrome has not been fully investigated. The aim of the study was to determine the connection between metabolic syndrome and pulmonary embolism and to evaluate the values of the glucolipid profile in patients with pulmonary embolism in metabolic syndrome. Methods: A cohort study included 305 patients with pulmonary embolism, divided into two groups: the first group with metabolic syndrome (n=165) and the control group without metabolic syndrome (n=140). The data was collected from May 2019 to May 2023. Demographic, anthropometric and laboratory parameters (glucose, total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides) were analyzed in all patients with confirmed pulmonary embolism. Results: Patients with pulmonary embolism in metabolic syndrome had statistically significantly higher values of glucose, total cholesterol, LDL cholesterol, triglycerides and lower values of HDL cholesterol compared to patients with pulmonary embolism without metabolic syndrome (p<0.05). Discussion: The results of our research indicate a strong need for a broad evaluation of metabolic abnormalities with special highlight on comorbidities and the need for a multidisciplinary approach to patients with metabolic syndrome. Assessing the risk of pulmonary embolism should become imperative in the treatment of patients with metabolic syndrome. Conclusion: Metabolic syndrome may play a key role in the pathogenesis of pulmonary embolism and may be a link between venous thrombosis, atherosclerosis and pulmonary embolism. Due to the complex relationship between hyperglycemia, dyslipidemia and pulmonary embolism, additional research is necessary to answer the question why people with metabolic syndrome have a higher risk of pulmonary embolism, as well as to determine appropriate preventive strategies.
Sewage sludge is a by-product of wastewater treatment. Sewage sludge is a desirable material for application in agriculture production as a fertilizer or soil conditioner, as it is characterized by a high content of organic matter and nutrients such as nitrogen, phosphorus and potassium. However, sewage sludge tends to concentrate trace metals, organic pollutants and pathogenic organisms due to the initial pollutant load of the treated wastewater and the treatment processes. Although various chemical methods can be used to remove trace metals from sewage sludge, the use of microbes is considered a more cost-effective and environmentally friendly approach compared to chemical treatments. This review examines the risks of trace metals in the application of sewage sludge and demonstrates the efficiency of their removal using physical, chemical and biological methods.
Short-wave infrared radiation allows for efficient heating of a body (target) with minimal thermal interaction with the gaseous medium through which it passes. The mutual geometric relationship between the infrared heating source and the target impacts the spatial resistances of radiation heat transfer. Therefore, a significant portion of the short-wave infrared radiation emitted by the heat source does not reach the target, thereby reducing its efficiency. To maximize the use of thermal radiation, this study analyzes a profiled nanofluid collector on which a heated target is placed. Nanofluid with Al2O3 nanoparticles flows through internal arrays of round nozzles and a profiled housing, being heated by the inner surface of the collector. The paper establishes a methodology based on the thermal irreversibility of the heat source, collector and nanofluid. The established methodology allows for minimizing thermal entropy in order to optimize the geometric and process parameters of the described system. The results of the conducted analysis are based on the cross-influence of the Reynolds number of the nanofluid, target and collector emissivity, short-wave heating time and nanoparticle volumetric ratio. The results obtained indicate that as the target emissivity, heater temperature and heating time increase, the thermal entropy of the mutual interaction between the heater and the target also increases significantly. Similarly, the thermal entropy of the mutual interaction between the collector and the nanofluid is greatly influenced by factors such as the Reynolds number (from 2000 to 4000), volumetric ratio (3% and 5%) and type of nanoparticles used (Al2O3, TiO2, and CuO). In this way, the specially designed collector allows for the utilization of captured heat, while the established methodology offers the opportunity to optimize the process-geometric parameters of the heating system being analyzed.
Climate change is one of the main challenges facing the population around the world. The consequences of these changes have been manifested for decades in various ways, creating disasters that threaten the lives of an increasing number of people. This paper analyses the consequences of the floods that hit the United Arab Emirates on April 16, 2024. After any natural disaster, this flood also calls into question the approach, preparedness and response to this challenge, questioning the success of managing critical infrastructure. This is an important question given that in the last two decades the United Arab Emirates has encountered several floods of a more serious scale. In line with the further development of the consequences of climate change and in response to the challenges they bring with them when it comes to the United Arab Emirates, the authors also propose specific guidelines for the relevant institutions as a way of improving critical infrastructure. A significant area would be to focus on the latest technology in creating superior public-private partnerships that would become modern, national-integrated emergency management systems. The authors used the Risk Management Theory, suggesting ways in which preventive responses can be made. The authors also used content analysis, as well as the observation method.
It is known that throughout history the people of Herzegovina have been good and skilled fighters and competitors, especially in wrestling, boxing, throwing maces, spears and knives, fencing, etc. Those fighting skills and various competitions were traditional activities of Herzegovinians and were nurtured, preserved and passed down from generation to generation. In the Middle Ages, in the area of today's Herzegovina, physical activities were nurtured and practiced, as well as in neighboring areas and countries. During the Turkish occupation (1463-1878) there was a halt in their development, while during the Austro-Hungarian occupation (1878-1918) sports and other physical activities and competitions began to be practiced more intensively. Numerous sports and other physical activities appeared and began to develop, such as: athletics, cycling, equestrian sports, roller-skating, bowling, hunting, fencing, football, climbing, swimming, wrestling, diving, sokolism, tennis, etc. In the Kingdom of SCS/Yugoslavia (1918-1941), this development became more intensive in terms of content and institutions. In addition to the already mentioned, also began the development of other sports, such as: basketball, folk sports, volleyball, skiing, archery, etc. After the end of the Second World War, sport gained full momentum in Herzegovina, especially in the form of institutional organization. The subject of this research is sport and other physical activities in the territory of Herzegovina, with the aim of making an overview of their origin and development up to the most recent times. During writing historical method was used.
Vehicle-to-everything (V2X) communications is an important part of future driver assistance and traffic control systems that will reduce accidents and congestion. The millimeter-wave (mmWave) band shows great promise to enable the high-data-rate links that are required or at least beneficial for such systems. To design such systems, we first need a detailed understanding of the vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2X) propagation channels. This paper provides a systematic account of a series of measurement campaigns for such channels, conducted by the four research institutions of the authors over the past year. After a description of the similarities and differences of the channel sounders used in the campaigns, a description of the measurements in two European and one American city is given, and the scenarios of convoy, opposite-lane passing, and overtaking, are described. This is then followed by key results, presenting both sample results of power delay profiles and delay Doppler (or angular) spectra, as well as the statistical description such as delay spread and size of stationarity region. We also discuss the availability of spatial diversity in V2I connections and the correlation of the channels between different frequency bands.
Food sovereignty is the human right to healthy and culturally appropriate food produced through ecologically sound and sustainable methods, and the right of people to define their own food and agriculture systems. Food security exists when all people, at all times, have physical and economic access to sufficient, safe, and nutritious food that meets their dietary needs and food preferences for an active and healthy life. In contrast to food security, which focuses on ensuring that enough food is available, food sovereignty emphasizes control over food production and distribution by local communities. Shifting the focus from food security to food sovereignty essentially represents a reconnection between nature, food, and people. The right to seeds is at the basis of each community’s food sovereignty, what is possible to achieve only in the system of farmers’ seeds. Farmer seed systems are a critical contribution to food sovereignty and farmers’ rights. For over 10.000 years, people have freely saved, selected, exchanged, and sold seeds, using and reusing them for sowing and food production. The farmers’ seed system is defined by the long-standing continuous renewal and free distribution of seeds and knowledge among people. Seeds are gifted, shared, or traded in informal and formal markets. These seeds are more resilient to climate change, pests, and pathogens, and they also ensure a more diverse food system and a dynamic global ecosystem. Today, farmers’ rights to seeds, crucial for their survival, are seriously threatened and are in decline worldwide. These seed systems are undermined by inadequate legislation and insufficient support from governments and public research, primarily as the result of a protected seed market based fundamentally on intellectual property rights and trade agreements. Farmers’ seed systems are vital for preservation of plant genetic diversity of all agricultural crops. It is increasingly expected that global climate change, combined with other factors, will significantly alter this agricultural biodiversity. Broad efforts will be needed to help reduce the climate vulnerability of current agricultural production systems and building more resilient and adaptive agroecosystems. The farmers’ seed system and the associated traditional agricultural practices are key factors for adaptation.
Background: The prevalence of obesity and obesity-related clinical conditions, including metabolic-associated steatotic liver disease (MASLD), sarcopenia, and a wide spectrum of pathological manifestations, is rising globally. According to WHO, BMI is the only anthropometric measure currently used to classify obesity, overweight, and underweight. However, emerging research suggests that obesity is a complex pathological state influenced by multiple etiological factors. Given the limitations of BMI, there is a growing need for a more comprehensive assessment of body composition, particularly fat mass quantity and distribution. Bioelectrical impedance analysis (BIA) provides valuable anthropometric data that can help differentiate obesity phenotypes and guide improved therapeutic approaches. Objective: This study aims to analyze body composition using BIA in a randomly selected sample of adults from primary healthcare settings in Bosnia and Herzegovina. The primary goal is to assess total body weight, fat mass quantity, fat distribution, and obesity types prevalent in this population. Additionally, the study seeks to establish reference values for further diagnostic, preventive, and therapeutic strategies to improve public health outcomes. Methods: A cross-sectional study was conducted on adults (≥18 years) in Gračanica, Bosnia & Herzegovina (B6H), from January 2021 to January 2025. Inclusion criteria required participants to provide signed informed consent, while exclusion criteria included acute systemic diseases, severe dehydration, and fasting for more than 24 hours. Anthropometric parameters measured included age, height, weight, BMI, body fat mass (BFM), fat-free mass (FFM), percent body fat (PBF), waist-hip ratio (WHR), and bone mineral content (BMC). Data were analyzed using SPSS (version 18), with results presented as medians, interquartile ranges, and percentiles (5th, 25th, 50th, 75th, and 95th). Results: A total of 4,628 adults participated in the study, of whom 2,824 (61.0%) were female and 1,804 (39.0%) were male. The median age was 45 years (IQR: 29 years). The findings revealed that over one-quarter of the B&H population is obese, with abdominal obesity being the predominant type. This phenotype is associated with the highest risk for metabolic syndrome and MASLD. Conclusion: Our study highlights a high prevalence of obesity among the examined individuals in primary care settings in B&H, with abdominal obesity being the most common type. This phenotype is strongly associated with metabolic complications. BIA-derived parameters of fat distribution and visceral fat mass may serve as valuable tools for improving obesity classification and developing more effective preventive and therapeutic strategies.
Background/Aim: The aim of this study was to conduct a comparative analysis of the oral health promotion programmes in the Balkan countries, to compare key measures and activities in the implementation of the programme, and to analyse the results achieved after the implementation of the programme. Material and Methods: Data were obtained through an electronic search of publicly available documents published in the field of dental healthcare in the Balkan countries. The search terms were: "national programme", "strategy", "action plan", "project", and "oral health". The search was conducted in English and in the native languages of the Balkan Peninsula countries. A comparative analysis of valid documents and those whose validity period has expired was carried out. Results: This study illuminates the information on preventive programmes for each country and discusses the challenges faced in the Balkans region. While countries in the Balkan Peninsula have made progress in improving the oral health of their inhabitants, the absence of national oral health promotion programmes is striking. Greater involvement of the community in activities to maintain and improve oral health is needed, as is more comprehensive dental care for vulnerable populations. Conclusions: The findings of this study may be employed to enhance oral health in the delineated regions, and to confer benefits upon the population of the region and beyond. The findings from this analysis provide valuable insights for policymakers and public health professionals aiming to strengthen oral health initiatives and ensure more equitable access to dental care across the Balkan Peninsula. This paper (Part II) describes specifics of oral health promotion programmes, dental health care, and key epidemiological indicators in each Balkan country.
The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has underscored the significant role of cardiovascular risk factors in determining the severity and outcomes of the disease. Pre-existing conditions such as hypertension, diabetes, obesity, and cardiovascular diseases have emerged as key contributors to increased susceptibility to severe forms of COVID-19, influencing both short-term and long-term health outcomes. This review examines the complex interplay between these risk factors and the virus’s direct impact on the cardiovascular system. Key findings suggest that conditions like hypertension, diabetes, and obesity not only predispose individuals to more severe disease but also exacerbate complications such as myocardial injury, arrhythmias, and heart failure. Furthermore, the long-term cardiovascular effects of COVID-19, including myocarditis and pericarditis, are of growing concern, particularly in patients with pre-existing cardiovascular conditions. The virus’s ability to induce myocardial damage through mechanisms involving ACE2 receptor binding and inflammatory cytokine storms has been well-documented. The pandemic has also highlighted significant cardiovascular complications, including left and right ventricular dysfunction, myocardial injury, and elevated pulmonary arterial pressure, with the right ventricle being particularly affected due to pulmonary damage. Imaging modalities such as echocardiography and cardiac magnetic resonance have proven valuable for diagnosing myocardial injury and complications, although accessibility may be limited in routine clinical practice. Survivors of severe COVID-19, especially those with pre-existing cardiovascular conditions, face an elevated risk of major adverse cardiovascular events for up to two years post-infection. Evaluation of post-COVID patients includes ECGs, laboratory tests, echocardiography, and cardiac MRI, which provide critical insights into myocardial injury and complications. Preventive measures, including vaccination, regular monitoring of cardiovascular health, and lifestyle modifications, play a crucial role in reducing the long-term risk of cardiovascular complications. The role of vaccination in mitigating the risk of severe disease and cardiovascular complications is well-established, despite rare cases of vaccine-related myocarditis. Understanding these interactions is essential for developing targeted management strategies, improving patient outcomes in both acute and long-term COVID-19 effects, and addressing the broader challenges posed by COVID-19’s impact on cardiovascular health.
