Accelerated urbanization represents one of the most significant pressures on the urban environment. The transition from "green" to "grey" amplifies the vulnerability of cities to the effects of climate change (temperature rise, floods, droughts, and air quality degradation). In this context, urban green spaces, and public parks in particular, acquire a strategic role as nature-based solutions (NBS). NBS are capable of providing essential ecosystem services such as mitigating the urban heat island effect, stormwate...

The Ciuc Basin is characterized by distinct climatic conditions that influence agricultural potential, hydrological balance, and regional climate resilience under ongoing climate change. This study analyzes temperature extremes and temporal variations of the Huglin Climate Index (HI), a widely used agro-climatic indicator for assessing viticultural and thermophilic crop suitability. The analysis is based on meteorological observations (temperature, relative humidity, and wind speed) from the national monitoring ne...

Among the existing methods of TMS processing, the most attention is paid to pyrolysis due to such advantages of this method as a high level of process control, the ability to adapt the process to a different composition of raw materials with a high yield of target products with specified characteristics, a closed-loop process, etc. [1, 2]. The study is devoted to the study of the process of co-pyrolysis and is aimed at developing a technology for thermocatalytic processing of complex organic waste of anthropogenic...

Design is inherently a decision-making process that involves generating alternatives whose evaluation allows for the improvement of the final intervention. In public contexts, decision-making requires a shared and participatory approach, as such processes are inherently characterized by multi-actor involvement and multidimensional considerations, especially in matters concerning sustainability and environmental governance. Participatory Multi-Criteria Evaluations (PMCEs) implement a multidimensional approach and c...

The growing interest in the development of artificial intelligence (AI) agents is increasingly influencing socially significant domains such as public administration, education, and government services. In these areas, AI systems are expected to achieve high standards of performance, including accuracy, reliability, and contextual awareness, in order to support administrative processes and provide citizens with fast and dependable access to information. For this reason, selecting an appropriate model conception is...

This paper is focused on the verification of two quasi-geoid models for the territory of Bulgaria (the model integrated into the Geodesy, Cartography and Cadastre Agency (GCCA) official product for the transformation of geodetic data and a model derived using the GNSS/levelling method) through direct geodetic measurements. The study was developed in the framework of the current 5th cycle of the 1st Order National Levelling Network (NLN), conducted in accordance with the requirements of the new 2021 Instruction [1]...

This paper focuses on the comparison of the energy potential of biomass originating from agricultural and viticultural production, with emphasis on its utilization in the form of pellets. Selected types of agricultural residues and viticultural wastes were analyzed, specifically grape pomace skins and pruning residues from vine cutting. These materials represent underutilized by-products with significant potential for energy recovery. The main objective is to evaluate the suitability of these materials as alternat...

This study presents a comparative analysis of three methodologies for deriving intensity–duration–frequency (IDF) relationships of rainfall in Bulgaria: (i) the method embedded in the current regulation for sewerage system design, (ii) the methodology used for estimating maximum river discharge, and (iii) a recently proposed regionalization approach with site-specific IDF curves. The objective is to evaluate their accuracy and applicability under contemporary climatic conditions, with a focus on urban drainage...

The monitoring of the construction behavior is one of the important activities carried out to determine the state of construction, subject to various natural and anthropogenic actions at a given time. In Romania, the activity of rockfill dams monitoring is regulated according to the importance category (A, B, C). The Rausor Dam is located downstream of the confluence of the River Rausor with the river Targului, which springs from the Iezer - Papusa Mountains in the central part of Romania. Being part of importance...

Arbuscular mycorrhiza, a widespread mutualistic association between fungi of the phylum Glomeromycota and plant roots, plays an important role in improving plant nutrition and tolerance to environmental stress. Through this symbiosis, fungi supply mineral nutrients and enhance resistance to drought and pathogens, while receiving assimilates from the host plant. This study was conducted on a commercial plantation of blueberry (Vaccinium corymbosum) in southwestern Slovakia. The plantation was inoculated with mycorr...
