Figs (Ficus carica) are renowned for their high antioxidant content and rich nutritional profile. They are an excellent source of vitamins (particularly vitamins A, C, K, and B-complex), essential minerals (such as calcium, magnesium, potassium, and iron), fiber, and bioactive compounds that offer numerous health benefits. Due to these properties, figs contribute to improved digestion, better blood sugar regulation, and enhanced cardiovascular health. Sausages are a widely enjoyed food, which inspired us to reimag...

This paper presents two AI-based case studies aimed at enhancing data-driven approaches to urban planning in relation to diverse topographical conditions towards sustainable development strategies and new urban typologies. The first case study employed a genetic algorithm to identify optimal spatial arrangements for agriculture, photovoltaic energy generation, and urban structure development. The analysis was conducted across three distinct Slovak topographies: riverlands, mountainous areas, and the existing urban...

This study investigates shoreline dynamics and morphodynamic variability along the Kavatsi coastal sector (Southern Bulgarian Black Sea coast) through a multi-temporal analysis spanning the 1980s to 2025. By integrating legacy topographic maps, aerial orthophotos, and recent high-resolution Unmanned Aerial System (UAS) photogrammetry (2020-2025), five representative beach-dune systems were assessed: Kavatsite-North, Kavatsite-South, Smokini-North, Smokini-South, and Camping Veselie Beach. UAS-derived orthophotomos...

The development of UAV-based (Unmanned Aerial Vehicles) diagnostic methods has created new opportunities for evaluating high-rise and industrial structures. While traditional multirotor drones are commonly used for visual and thermal inspections, their limited authority control reduces precision when operating close to complex surfaces. This review paper examines the capabilities of omnidirectional UAVs (omnicopters), which offer full control across six degrees of freedom by decoupling translation from rotation. S...

Unmanned Aerial Vehicles (UAVs) have become essential platforms in domains such as logistics, environmental monitoring, surveillance, agriculture, and disaster management. The growing complexity of missions and the increasing demand for autonomy highlight the critical role of trajectory optimization, which ensures safe, efficient, and adaptive navigation in dynamic environments. Path-planning algorithms form the core of this capability, enabling UAVs to avoid obstacles, minimize energy consumption, and accomplish ...

Human activities on a global scale are increasingly generating substantial quantities of solid waste. Consequently, in recent years, there has been a significant worldwide initiative to reduce waste production and reuse existing waste, including non-recyclable plastics, industrial waste, sewage sludge, hazardous waste, municipal waste, among others. To ensure environmental quality, further treatment of waste is essential to prevent its accumulation in landfills. For waste materials that cannot be recycled or for w...

The aim of this study is to analyse the impact of the Urban Heat Island (UHI) effect on temperature dynamics across various locations within the city of -ilina during the year 2024. The results reveal significant differences in temperature gradients between urban and rural areas, with urban zones such as Nemocnicna Street and the Vlcince housing estate exhibiting up to 16.6 % slower cooling rates on summer evenings compared to the rural locality of -ilinska Lehota. This phenomenon is attributed to the increased he...

Urban soil contamination with heavy metals is a growing environmental concern due to its adverse effects on human health, ecosystem stability, and soil productivity. The primary sources of this pollution include industrial activities, vehicular emissions, atmospheric deposition, mining operations, and improper waste disposal. As heavy metals such as lead (Pb), cadmium (Cd), mercury (Hg), arsenic (As), and chromium (Cr) accumulate in the soil, their persistence and low mobility make them difficult to degrade or rem...

Remote sensing techniques are increasingly used in land surface monitoring processes. The development of satellite systems has led to increasingly complex research in terms of analysis and monitoring of large land areas, with reduced costs and high efficiency. In this research, a satellite scene from 03.07.2024 taken over by the Landsat 9 remote sensing system was used, the scene identifier being LC09_L2SP_186028_20240730_20240731_02_T1, WRS_PATH 186 and WRS_ROW 28, UTM projection system, Datum WGS84, Ellipsoid WG...

The use of remote sensing images in territorial analyses is increasingly used with the development of remote sensing systems. Due to the fact that there are numerous remote sensing systems, both open source and paid, these instruments are widely used in monitoring large areas in order to analyze the dynamics of land use changes. In the present study, an analysis of the ATU Moravita, Timis County, Romania, was carried out based on remote sensing images taken from the Landsat 8 satellite system. Based on the 11 spec...

The submitted paper focuses the issue of using a new technology of Near Infrared Reflectance (NIR) sensors in practice for dosing organic fertilizers based on their composition. The HarvestLab 3000 system was tested in a selected enterprise in terms of its usability in practice. In 2021, an experimental plot was selected in a conventional company situated in the southern part of Czech Republic. The HarvestLab 3000 system with the NIR technology was used for the variable (VR) dosage of digestate as a basic fertiliz...

The relevance of this research stems from the critical importance of protecting environmental rights under conditions of martial law. Violations of these rights can lead to long-term environmental degradation and adverse impacts on public health. As of the 1000th day of the war, environmental damage to Ukraine caused by the aggression of the Russian Federation has reached an estimated USD 70 billion. Approximately 3 million hectares of forests have been destroyed, over 6,500 environmental violations recorded, and ...

Non-destructive testing (NDT) of 3D-printed concrete is challenging due to complex geometries and layer-dependent material heterogeneity. Photogrammetry captures surface geometry, but its outputs cannot be directly linked to NDT values. This study presents a workflow that integrates photogrammetric models with rebound hammer measurements and applies radial basis function (RBF) interpolation to visualize near-surface strength. Each measurement point is matched to its 3D coordinates on the mesh, enabling consistent ...

The study aims to analyze the vulnerability of the water supply within the water resources management system of the Tundzha River basin. It evaluates available water resources and the possibilities for their management, with a focus on the hydrological efficiency and economic feasibility of management strategies, as well as the social implications of their implementation. The methodology includes the application of a water resources balance for the entire catchment to assess the correspondence between resources an...

Acid mine drainage (AMD) is a significant environmental issue especially in countries like Bulgaria that currently has 486 closed and abandoned mining waste facilities including tailings, dumps and heaps. Some of them are thoroughly investigated and known for their low pH levels and high metal and metalloid concentrations. The most conventional active treatment method for AMD involves neutralization through the use of different reagents. However, a significant limitation in the application of this method is the la...

The study examined the sorption properties of beech, chestnut, and pine sawdust, as well as pine pellets, focusing on their ability to remove heavy metal ions from aqueous solutions. The kinetics of sorption were analyzed using CuSO4-5H2O and FeSO4-7H2O solutions (10?5-10?- M) over 1, 2, 4, 24, and 48 hours. Sorbents were modified with HCl and NaCl, and their efficiency was evaluated by measuring pH and electrical conductivity before and after sorption. Chestnut sawdust demonstrated the highest sorption capacity, ...
