Magnetic Prospection of a Tumulus in the Ancient Histria Necropolis

Abstract. Near surface geophysical investigations are employed in archaeology in order to estimate the location, depth, shape and physical properties of buried ancient structures. The geophysical study initiated in 2008 on tumuli located in the Histria necropolis was based on magnetics, the measurements being carried out with a proton precession magnetometer / gradientmeter. The networks where measurements of total magnetic field and magnetic vertical gradient were performed covered each tumulus and small adjacent areas. The magnetic measurement points situated at 2 m interval represented detailed rectangular networks. The necropolis is situated at ca 2 km north-west of Histria ancient Greek city and includes a great number of tumuli of various dimensions and trends. Previous archaeological studies evidenced different rituals of burial for the ca 1300 years of continuous inhabitation during Greek colonization and Roman / Byzantine empires. The magnetic data obtained for the tumulus analyzed in this paper, located toward the north-western limit of the Histria necropolis, suggest quite complex archaeological features, similar to those observed in the excavations. Generally, metallic artifacts, a clay layer affected by fire or active magnetic rocks employed in the buried infrastructures may represent sources of high magnetic anomalies. The magnetic total field and vertical gradient anomalies are interpreted as being here mainly due to burnt materials and buried greenshist structure (high anomalies), or to an outer stone belt made of limestone boulders (low anomalies)

The Collaborative Economy through the Lens of Sustainable Tourism. A Regional-Centric View

Nowadays the tourism industry faces major changes given the vast possibilities for the development of a collaborative economy in tourism that brings forth a new marketplace where consumers rely on each other -changing renting, swapping, and sharing their accommodation locations. The purpose of the present paper is to answer one of the most important challenges of the City of Brașov in Romania, which is the management of the touristic offer. The paper provides a quantitative-qualitative research approach that analyzes - based on semi-structured surveys with the users of collaborative platforms - the perception of travelers concerning the development of collaborative tourism in Brasov County. The management of touristic offer should take into account the pressure that this new type of renting may be exerting on the local economy, especially considering unfair competition on other segments of the tourist market and the change in the physiognomy of the cities of Brașov County

A story about how the novel ROSPIN Academy programme is bringing space education to the Romanian youth in the pandemic context

Continuous education is the foundation of a sustainable society and ecosystem, and this paper relates the story of one of the most ambitious educational programmes for University students from Romania. The country acceded to the European Space Agency’s Convention in 2011, but does not have a dedicated undergraduate programme for space education, although the local space industry is growing and is demanding more skilled professionals. In this context, the Romanian Space Initiative has been organizing the ROSPIN Academy educational programme since the spring of 2021. Currently, each Edition of the Academy has 3 Levels, coordinated with the least busy University periods: Level 1 is an introduction to the space sector (autumn 2021), Level 2 consists of a technical overview of the lifecycle of space missions (spring 2022), and Level 3 offers hands-on experience with industry (summer 2022). Although the curriculum’s core is spacecraft engineering, it aims to reflect the sector’s interdisciplinarity, so topics such as astronomy, space sustainability and policy are also covered. The Lessons are delivered in English by national and international speakers from industry and academia, ranging from young graduates to experienced professionals. Participants can interact directly with them, in a context that promotes the idea that space is not only for rocket scientists. The participants’ interpersonal skills are also trained through exercises and games about space topics, which require them to work together in teams. The accepted participants of the Academy are selected based on their motivation and thinking, relevant knowledge and compatibility with the Academy learning concept. Currently, more than 400 applicants have been accepted in the past or current Editions of ROSPIN Academy. Last but not least, the national outreach achieved through this programme is a key defining value. ROSPIN Academy is present at national level, across industries, and mixes undergraduates and graduates, with focus on the former. This is demonstrated by the evolution of the distribution of the accepted participants, in terms of city, year and field of studies. Due to the organisation’s efforts to promote the second Edition nationwide with the support of professors from the biggest STEM Universities, this distribution has clearly evolved. Edition 2 shows a more diversified pool of participants compared to Edition 1, which mostly had active participants with aerospace background from Bucharest. As a result, ROSPIN Academy is uniting the local space communities while educating the next generation of space engineers

For or Against the Eurozone? Romanian Students’ Perspective on the Economic Crisis and Their Future as European Citizens

In the context of globalization and of the aftermath of the economic crisis, the pillars on which the EU stands no longer satisfy the demands and necessities of the European citizens (Van Ham, 2005; Habermas, 2012).  The euro crisis has generated, on one hand, a gap between the “center” and the “periphery” that can be correlated with the fragmentation both of the EU’s spheres of influence and of the European financial market (Dobrescu & Palada, 2012; EFCR, 2013).  On the other hand, the euro crisis has generated a lack of solidarity and confidence in the European project. At this point, the major challenge for the European Union is not only the Euro-zone crisis, but also the level of confidence amongst young people. Recent polls (Gallup, 2013; Pew Research Center, 2013) indicate a dramatic rise in pessimism among Europe’s young people that have been labeled as “the Lost Generation” (European Commission, 2012). This paper explores the impact of the economic crisis on Romanian students’ attitudes towards the future of the European project and towards their European identity. The study aims at identifying the major concerns of Romanian students in terms of their future as European citizens. Our approach of this subject covers two perspectives: the first one is the utilitarian perspective, that is taking into consideration the actual advantages of the Europeanization process and the sustainability of the European social and economic model in the current national economic context; the second one is the identity perspective, that is taking into account the impact of the economic crisis on the Romanian students’ sense of belonging to the European community. The results of our study indicate that, overall, the Romanian youth holds an optimistic view concerning the EU, however they express some concerns in terms of lack of solidarity and fear of national identity loss

Aspartame-Stabilized Gold-Silver Bimetallic Biocompatible Nanostructures with Plasmonic Photothermal Properties, Antibacterial Activity, and Long-Term Stability

Gold-silver core-shell nanoparticles stabilized with a common sweetener, aspartame (AuNP@Ag@Asm), combine the antimicrobial properties of silver with the photoinduced plasmon-mediated photothermal effects of gold. The particles were tested with several bacterial strains, while biocompatibility was verified with human dermal fibroblasts.Fil: Fasciani, Chiara. University of Ottawa.
