Research on Consumer Perception Regarding Traditional Food Products of Romania

Traditional Romanian food products are an integral part of local culture and spirituality. These food traditions have been formed over the centuries and represent a particularly important part ofthe development of a circular economy in rural areas. In order to contribute to the development of this sector of activity we conducted a study on consumer perception of traditional Romanian food products. The purpose of this work was to identify the structure of the studies and the future directions of research related to the image of traditional food products through the bibliometric study, as well as the identification of consumer trends, of these products through a survey based on the questionnaire. The results obtained indicate that traditional Romanian food products are consumed by the majority of respondents participating in the survey and that this sector ofactivity has continuity in its development and presents a clear interest among citizens.

Integrated approach of the entrepreneurial behaviour in the tourist sector from disadvantaged mountain areas from Romania

The economic development of the tourism in disadvantaged mountain areas has the role of sustaining their development and economic growth. The premise of a successful development of tourism in these areas is given by the authenticity of resources. This paper aims to highlight the strategic perspectives/outlook of tourism in disadvantaged mountain areas through the evaluation of strategic alternatives using the concerted analysis SWOT-AHP. The aim of this study is to support communities and actors involved in the phenomenon of tourism in disadvantaged mountain areas in order to achieve positive results and as much as possible with awareness and avoidance of risks, and prevention or combating negative consequences. During the research and analysis, in accordance with the literature, the issue of entrepreneurship was treated as a dependent variable, and the phenomenon of tourism as an independent variable. The vision of tourism planning in disadvantaged mountain areas must focus on its sustainable development that contributes to increasing entrepreneurial initiatives by diversifying and ensuring the complementarity of tourism services calibrated to the needs of tourists and adapted to new social challenges. The strategic planning in the area of the tourism of disadvantaged mountain areas represents a topical challenge in the context of promoting sustainable tourism. Currently, there is a strategy at national level for developing tourism, but there is no strategy for developing tourism in disadvantaged mountain areas.

Iron oxide-based nanoparticles with different mean sizes obtained by the laser pyrolysis: structural and magnetic properties

Nano-sized iron oxide-based particles have been directly synthesized by the laser induced pyrolysis of a mixture containing iron pentacarbonyl/air (as oxidizer)/ethylene (as sensitizer). In this paper we further demonstrate the possibility to vary the chemical composition and the nanoparticle dimensions of the iron oxide-based materials by handling the oxidation procedure in the frame of the laser pyrolysis process. Thus, nanoparticles with major maghemite/magnetite content may change composition into mixtures with variable amounts of three components: major gamma-Fe2O3/Fe3O4 iron oxide, metallic Fe and cementite Fe3C. By X-ray diffraction (XRD) it is found that the relative proportion of these phases differs in function of the reaction temperature (laser power). As revealed by transmission electron microscopy (TEM), mean particle sizes between about 4 nm and 6 nm and between about 9 and 11 nm may be prepared by varying the oxidation procedure and the laser power, respectively. By the controlled heating of samples (maximum temperature 185 degrees C), increased crystallinity for the gamma-Fe2O3/Fe3O4 oxide phase was found as well as an increase of the mean particle diameters. The examination of the magnetization curves for samples obtained for different laser powers indicates notable differences in the magnetic behavior and parameters. The temperature dependent Mossbauer measurements confirm the formation of larger particles at higher laser power densities as well as the presence of inter-particle magnetic interactions. On this basis, the estimation of phase composition for the different representative samples is given.
