This study aims to assess and monitor the health of an urban protected area by analyzing the levels of persistent organic pollutants (POPs) and mercury (Hg) in soil and sediments. Based on the results, the detected concentrations of organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and Hg are above the threshold maximum values for soils, and the prescribed target values for sediments. In the investigated protected area PCBs pose a very high ecological risk. The presence of 16 priority PAHs in analyzed soils and sediments poses a moderate to high cancer risk and Hg poses a considerable health risk to children. The research suggests that preserving urban protected areas is crucial for environmental and urban sustainability. In urban environments these areas should be evaluated in terms of their environmental, eco-geochemical, economic, and socio-cultural dimensions. The value of the existence of this natural oasis lies in its aesthetic and psycho-hydrological impact, local climate regulation, residential isolation, and significant art-architectural and horticultural shaping. The connection between eco-geochemical and management practices, planning, and urban green spaces policy should become an adopted innovation in the cities in the future.
Ragweed is a neophyte which inhabits various crops and ruderal habitats. That is the reason why this paper is dedicated to phytocenology and ecological relations of ragweed in such a habitat. Research was carried out in the area of a former railway freight and customs terminal, in the period from 2021 to 2023. Phytocenological image was made and all the parameters were assessed: life form, phytocenological affiliation, floral elements, indicator values, and soil analysis. The aim of the paper is to present the places where ragweed may be found, as well as under what ecological conditions and with what other species it occurs. This research yielded new data on the phytocenology of ragweed, determined in the vegetation of the order Chenopodietalia. A total of 69 species from 23 families were identified. The most numerous is the Asteraceae family. Phytocenologically, the largest number of species belongs to the order Chenopodietalia, and as far as the indicator values are concerned, the most numerous are the representatives of tertiary vegetation. Hemicryptophytes predominate regarding life forms, and concerning the floral elements, 40 different elements from 9 groups were noted. The most numerous group are Eurasian species, and the most numerous individual floral elements are euras-smed and eurassubozean-smed.
During the three-year field research (2019-2022) in the area of the Canton of Sarajevo, we discovered many invasive plant species in localities where they had not been recorded before. Among them, Ailanthus altissima (Mill.) Swingle, Ambrosia artemisiifolia L. and Reynoutria japonica Houtt. stand out in particular due to their abundance and coverage. This study aimed to provide data on the localities where these invasive plants were found, including altitude, longitude and latitude, soil type and their floristic and phytocoenological features. Data from these localities should contribute to the creation of a database that can be used for more a efficient fight against the aforementioned invasive species. In total, 42 new localities were recorded for Ailanthus altissima, 10 for Ambrosia artemisiifolia and 15 for Reynoutria japonica. Due to their abundance and appearance, Ailanthus altissima and Reynoutria japonica have already become a big problem for urban horiculture in Sarajevo, while Ambrosia artemisiifolia poses a health concern, and therefore, urgent measures and necessary to remove them.
The financial industry is experiencing a digital revolution fueled by the fourth industrial revolution. While digital tools are widely adopted, the specific impacts of digitalization and innovation on financial markets and citizens remain under-researched. This study investigates the relationship between technological progress and innovation with the development of financial markets, the Human Development Index, and the Gross Domestic Product per capita. The core question is how, and to what extent, technological advancement and innovation influence financial development and other social and financial performances per capita. The research employs regression analysis, specifically simple linear regression, and integrates existing research and theoretical frameworks to build an inductive approach. Findings indicate that a one-unit rise in technological progress is linked to a 0.5unit increase in the financial development index (p-value < 0.001). These findings suggest that financial intermediaries and decision-makers in developing countries should consider altering their business models and adapting to rapid technological changes to enhance financial development. This paper provides insights into the connection between progress in digitization and outcomes in the economy and finance, emphasizing the importance of adapting to swift technological changes for sustainable development.
Here we demonstrate quasi-phase-matched up- and down-conversion in a periodically poled van der Waals semiconductor (3R-MoS2). This work opens the new and unexplored field of phase-matched nonlinear optics with microscopic van der Waals crystals.
The aim of this paper is to identify models for preventive risk recognition as tool for crine prevention in the renewable energy sector through a systematic review of the available literature. These models should represent a formalized set of steps or protocols that can be used at any stage of renewable energy projects, particularly in the construction of renewable energy power plants, to mitigate and minimize the risk of criminal offenses. Models of preventive risk recognition ensure that the power plant construction project progresses smoothly from start to finish without unnecessary financial losses due to their ability to identify all weak points in the entire process. With the help of the models described in this paper, the transition to green energy is accelerated and sustainable development is fully supported,
This paper examines the complex landscape of digital currencies, non-fungible tokens (NFTs), and distributed ledger technology (DLT), focusing on their implications within the accounting and financial reporting sector. The surge in popularity of these assets has brought about reporting challenges and complexities. The lack of comprehensive accounting standards and the digitization of financial reporting processes further compound the situation. These challenges underscore the need to update accounting practices to align with the security and transparency offered by DLT. The study examines the International Financial Reporting Standards (IFRS) for digital currency reporting, analysing their implications and potential solutions for the accounting community. Central to this exploration is the question: How can the accounting sector navigate the multifaceted challenges and harness the multifarious opportunities that stem from digital currencies, NFTs, and DLT? Using a comprehensive research approach, including a literature review, empirical analysis, case studies, and comparative analysis, this study identifies strategies for managing the reporting complexities of digital assets. It also highlights the importance of collaborative dialogue between stakeholders and regulators to ensure consistency in an evolving landscape. This paper guides the accounting and investment sector in making informed decisions, fortified by a nuanced understanding of the evolving digital asset terrain.
Atherosclerosis and endothelial dysfunction are responsible for 80% of cardiovascular diseases. It's important to understand the disease's pathogenesis to determine the best prophylaxis and therapy. Diabetes mellitus contributes to the development of atherosclerosis and endothelial dysfunction, and keeping blood sugar levels in check is crucial. Cardioprotective, nephroprotective, and lipid profile drugs should be preferred to DM treatment. GLP-1 receptor agonists or GLP-1 analogues have cardiorenal benefits and can be used for various indications. The objective of this review is to examine the role of GLP-1 analogues in the treatment of diabetes mellitus (DM), focusing on their cardiovascular benefits as demonstrated by Cardiovascular Outcome Trials (CVOT). Additionally, the review aims to highlight the significance of GLP-1 analogues in the primary and secondary prevention of cardiovascular events. It also proposes the hypothesis that these analogues may benefit patients with heart failure, regardless of whether the systolic function is reduced or preserved. We searched of databases and online libraries, including PubMed, Scopus, and Cochrane, using keywords such as GLP-1 agonist, diabetes mellitus, and cardiovascular diseases. Our search focused on articles published between 2011 and 2023. Antidiabetic drugs have shown a potential impact on cardiovascular risk and benefit. Liraglutide and semaglutide have outperformed placebo, but the mechanisms behind their benefits remain unclear. Prioritizing cardiovascular safety and preventing complications is essential for patients with T2DM when selecting a treatment.
The purpose of the paper is to investigate the presentation role in study selection. Presentation and promotion of studies are major issues that academic institutions focus on in order to attract students. The study included students from the University of Sarajevo’s I, II, and III cycles of tourism and environmental protection. Three kinds of reference criteria and indicators were selected: attractive presentation features, promotion approach, and presentation influence on decision. The study’s findings revealed that the faculty’s official website and recommendations are the most influential marketing tools, that the presentation of the study influences choice and decision-making, and that the study’s conception, the modernity of the educational infrastructure, field teaching, as well as the geographical aspect of tourism and environmental protection, are particularly appealing factors.
Since the 1960s, the rapid advancement of information technology (IT) infrastructure has been covered by the innovation of new electronic devices. This progress has not only accelerated industrial growth but also enhanced the quality of human life. Modern electronic devices are highly advanced and contain numerous components. Traditionally, Sn-Pb solder alloys have been the preferred choice due to their many advantages, such as ease of use, low melting point, favorable working conditions, good ductility, and excellent wetting properties on copper and its alloys. However, due to the toxic effects of lead on both health and the environment, limit the use of lead. As a result, the development of lead-free solder alternatives has been a focus for the past thirty years. To investigate new solder materials extensively, it's crucial to understand phase diagrams, phase equilibria, and melting points. Thermodynamic calculations and modeling are key in producing a consistent dataset and predicting thermodynamic properties. Muggianu Model and Model Toop were used to calculate the thermodynamic properties of Al-Ga-Sn liquid alloys. The predicted values were compared with the calculated results of the General Solution Model, and published experimental data confirm that the models are both accurate and practical.
