Department of Economy and Rural Development, Faculty of Gembloux Agro-Bio Tech, University of Liège, Passage des Déportés, 2, 5030, Gembloux, Belgium.
The present study investigates environmental perceptions in Romania, emphasizing their role in shaping individual and collective responses to ecological challenges. By exploring how people understand and interact with their natural environment, the research aims to explore values, needs, behaviors, and motivations that drive pro-environmental actions. We used a mixed-methodology approach, combining qualitative and quantitative analyses to capture a comprehensive view of these perceptions.

The subject of our present investigation is the collective electronic properties of various types of pseudospin-1 Dirac-cone materials with a flat band and finite bandgaps in their low-energy spectra. Specifically, we have calculated the dynamical polarization, plasmon dispersions, as well as their decay rates due to Landau damping and presented the closed-form analytical expressions for the wave function overlaps for both the gapped dice lattice and the Lieb lattice. The gapped dice lattice is a special case of the more general-T3model such that its band structure is symmetric and the flat band remains dispersionless.

Rationale: The stable isotope compositions of atmospheric CO can provide useful insight into various geochemical processes and carbon cycles on Earth, which is critical for understanding of Earth's changing climate. Here, we present a simple and cost-effective analytical method for the collection and measurement of carbon and oxygen isotope compositions of atmospheric CO.
Methods: Air samples of ~150 mL were collected individually or collectively using our simple active air collection system and then extracted on a vacuum purification line to remove noncondensable gases and atmospheric water vapor.
