Amid increasing challenges associated with urbanisation and climate change, urban resilience has become a central focus in scientific research. The rapid evolution of this field has resulted in fragmented theoretical perspectives, which hinder a comprehensive interpretation of current studies. This study aims to identify the principal dimensions of urban resilience and to systematise them through bibliometric analysis. The identified research gap is the absence of a coherent conceptual framework that integrates contemporary trends in urban resilience research. The study introduces an original conceptual framework comprising five dimensions of urban resilience and an overarching dimension of disruption that integrates the remaining components. The methodology includes a literature review and bibliometric analysis of works published between 2010 and 2025 and indexed in the Scopus database, utilising keyword co-occurrence analysis in VOSviewer. The findings reveal that recent research predominantly addresses administrative-managerial and infrastructural-spatial dimensions, whereas environmental, economic, and social dimensions are comparatively underrepresented. This study consolidates the existing body of research on urban resilience. It presents a conceptual framework for green urban resilience, which may serve as a basis for future investigations into the development of the urban resilience concept.
The development of microbial fuel cell (MFC) technologies represents a key direction in improving wastewater treatment methods. This approach allows for simultaneous wastewater pre-treatment and energy recovery in the form of bioelectricity. However, one of the primary obstacles to the broader application of MFCs is their limited electricity output. As a result, increasing the efficiency of this process remains a central research objective. In this study, a carbon-based electrode (carbon felt, CF) was used as the anode in MFCs. For the cathode, copper mesh modified with various non-precious metal catalysts (CF, stainless steel, Cu-B, Ni-Co) was employed. The experiments were conducted in glass MFC reactors, with sintered glass serving as the chamber separator. Several electrode configurations were tested: CF/CF, CF/SS, CF/Ni-Co, and CF/Cu-B. Experiments were conducted using a glass reactor (glass MFC) equipped with carbon-based electrodes. To reduce costs, a foamed glass membrane was used as the separator. Bioelectricity generation was observed in all tested configurations. Among them, the CF/Ni-Co system demonstrated the best overall performance, providing faster start-up, higher power density.
Biodegradable composites based on PLA, PHB and a PLA/PHB (80:20) blend with 0, 5 and 10 wt% wood fibers were injection molded into ISO 527 Type 1A specimens. Samples were produced on an Engel Victory 200/50 fast track injection molding machine using a two channel, uncooled mold. Density, Shore D hardness, tensile properties, unnotched impact strength and fracture surfaces were examined. Wood fibers caused small increases in density and only minor changes in hardness, but consistently raised Young’s modulus. At the same time, they reduced tensile strength, elongation at break and impact strength, leading to material embrittlement. The polymer matrix determined the baseline stiffness and ductility, while fiber content shifted the stiffness-toughness balance and increased variability at 10 wt% filler. Microscopy confirmed brittle fracture with fibers dispersed throughout the matrices.
The study focuses on a multi-indicator assessment of groundwater quality in south-western Poland with regard to its suitability for municipal and agricultural purposes. The Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI ) was applied to evaluate water for drinking purposes, while Soluble Sodium Percentage (SSP), Sodium Adsorption Ratio (SAR), Kelley Ratio (KR), Magnesium Adsorption Ratio (MAR), and electrical conductivity (EC) indices were used to determine its quality for irrigation. The analysis covered data from 26 monitoring sites collected between 2005 and 2024, taking into account spatio-temporal variability as well as the influence of natural and anthropogenic factors. The results revealed considerable variability in water quality, with CCME WQI values in 2024 ranging from 49.62 to 100. The most significant negative impact on water quality was attributed to iron (Fe), manganese (Mn), and ammonium (NH4+), showing strong negative correlations with the CCME WQI (r =-0.898,-0.756, and-0.575, respectively). In some sites, exceedances of up to tenfold for Fe and fortyfold for Mn were recorded, which may pose risks to both human health and infrastructure. Irrigation suitability indices generally indicated good quality, although locally reduced suitability was observed, mainly related to elevated EC. The study demonstrates the necessity of a site-specific approach to managing groundwater quality, which takes into account local pollution sources and hydrogeological conditions. These findings could inform remedial actions, optimise water treatment and ensure the sustainable management of water resources in agriculture.
This article examines the use of mobile Geographic Information Systems (GIS), particularly the Flora Incognita application, for documenting vegetation along the green ecological trail in the Barlinek Landscape Park. The study evaluates the usability of the application, the accuracy of plant identification, and its potential to generate high-quality georeferenced data. The results indicate that Flora Incognita is an efficient and cost-effective tool for rapid floristic surveys, achieving high identification accuracy which, when complemented by expert verification, can significantly enhance monitoring efforts. The analysis demonstrates how citizen-generated data can be utilized to develop dynamic spatial databases, supporting park management in tasks such as mapping invasive species and tracking phenological changes. The article concludes that, although mobile GIS applications cannot replace traditional scientific methods, they represent a complementary approach that promotes public engagement and contributes to a more comprehensive understanding of local and macroecological patterns.
