Introduced in Europe for the first time as a medicinal plant (around the 1630) and later as an ornamental, Asclepias syriaca L. has escaped from culture and became subspontaneous. Today, this species raises serious threats of invasion in some European countries, such as Hungary, for example. In this paper, we discuss the spread of the species in the Romanian Banat, especially in the spontaneous vegetation. The first reports in the region are those from the Romanian Flora. We found this species in different habitat...

Pervasive environmental stressors, particularly water deficits, have a major impact on plant production, diverting necessary energy away from growth and development to mitigate stress effects. This study addresses the impact of several water regimes (irrigated and non-irrigated) on royal walnut individuals (Juglans regia L.) in an orchard in western Slovakia. Our analysis focused on sap flow measurements using the stem heat balancing method from July 13 to September 21, 2021. In the midday hours, the sap flow rate...

Construction using 3D printer technology seems to be not just a passing trend and a growing number construction companies are approaching this new construction methodology. Although construction processes with printers are becoming standardized, it is also true that many other aspects must be considered in the design phase. Better this construction methodology becomes known, more architects and engineers will have to learn how to design these constructions, in the methods of statics, systems, etc. A very important...

The layered cobaltites have great potential for use in thermoelectric generators due to their environmental friendliness, good thermal and chemical stability, and relatively low cost of raw materials. Improving the thermoelectric prope...

In the present, regional policy faces the demanding task of developing suitable decision-making tools for regional development that will effectively take into account the need to mitigate climate impacts. Blue-green infrastructure (BGI) emerges as one of the most promising tools in this field. BGI represents an integrated approach that harnesses the synergistic effect of natural and civic systems to manage water, regulate climate, and protect biodiversity. This comprehensive approach not only helps reduce the risk...

The relationship of contemporary human beings to the nature is in the centre of the public debate worldwide and in particular countries because of climate change. Different social groups develop different perspectives on the issue based on ideologies, values and lifesyles. They express it through verbal arguments, but also through visual messages that use well known symbols and emotionally louded images in public spaces one of forms usual for supposedly muted groups beeing stencil graffiti. The aim of this researc...

In the area of the city of Piatra-Neamt (North-East of Romania), the activities related to the tourism sector may register malfunctions due to the manifestation of some natural risk phenomena. The touristic potential of the city (recreational, sports, balneary, cultural-historical) represents a central component of the national tourist structure with many exploitation possibilities. Risk situations of tourist activities can be induced by the natural hazards attributes (probability and intensity) and vulnerability ...

Education is an ongoing process that enables individuals and society as a whole to reach their full potential by developing their abilities. It serves as a crucial prerequisite for sustainable development and the formation of public awareness. Environmental education, which begins in early childhood and continues throughout life, plays a vital role in fostering environmental literacy. Thus, assessing the state of environmental education among school-age students is of great importance. Our research aimed to evalua...

Most modern heat pump installations can only generate a maximum temperature of 50-55-C. This temperature potential is not sufficient to integrate them with existing convective and radiator-based space heating systems in severe climates. This paper discusses the findings from an experimental study evaluating the efficiency of a fan coil-based air heating system. Using a peaking boiler fueled by natural gas from the main supply has been shown to be the most cost-effective method for generating thermal energy with pe...
