Development of "dark" tourism in the contemporary society

The paper focuses on the development of „dark“ tourism as a type of special interest tourism. The study included analysis of the definition of „dark“ tourism, tourist motivations for this type of tourism, Stone' s typology of dark destination offers, and a portion is devoted to the role of „dark“ tourism in contemporary society. Also there are important „dark“ tourism destinations in the world as an example of this type of tourism development. The work includes a reference to the promotion of dark tourism in Romania, as a destination that has largely failed to impose itself on the world tourism market because this form of tourism promotion. In the first part special attention is paid to the special interest tourism, which is a new development that drives modern society. Modern tourists have a different kind of motivation when they are planning travel and tour operators need to focus on current trends. One of the trends relating to the development of „dark“ tourism and some of the countries at the national level is positioned as a destination which are distinguished by this kind of tourism. There is the space for this type of tourism development, but they require specific solutions that are distinctive to each country

Green Growth as a Generator for Overcoming the Crisis

Faced with the severest economic crisis after World War Two, the global economy is turning to new sources of growth, which should guide it on the road to economic recovery. In such circumstances, the idea of green growth, based on the belief that economic growth and care for the environment go "hand in hand," is being reaffirmed. In a way, green growth represents a step backward, i.e., going back to the UN Conference on Environment and Development held in Rio in 1992, when environmental sustainability of economic growth was the focus of attention. On the other hand, green growth also represents a step forward, as it is a practical and flexible approach that should contribute to the implementation of the concept of sustainable development in all its dimensions:economic, environmental and also social. A large number of countries, including the European Union, follow the green growth model, respecting national idiosyncrasies, which is demonstrated in this paper. In order to communicate with Europe and the world successfully, Serbia needs to share their fundamental values and commitments, but also preserve its national economic identity. Green growth (in the context of sustainable development) is a good option for Serbia and is its strong link to the rest of the world

Comparison of Enzyme-Linked Lectin Sorbent Assay and Flow Cytometry for Profling Microbial Glycans

The surface of microorganisms is covered with carbohydrates, which makes them unique, self-sustaining glycan probes. Lectins are able to bind to these probes, and this interaction can be exploited for selecting microorganisms or novel lectins. To examine lectin-microorganism interactions, we have previously developed an enzyme-linked lectin sorbent assay (ELLSA) with whole bacterial cells. To further test the validity of this methodology, here we compare it with flow cytometry. For this purpose, we used biotinylated recombinantly produced lectin from Musa acuminata (BanLec), this lectin’s recombinantly produced chimera with green fluorescent protein (BanLec-eGFP) and a lectin from Ricinus communis (RCA120), both biotinylated and FITC labeled. Parallel testing showed equivalent results for the two methods, in terms of the presence or absence of binding, with signal intensity yielding high Pearson correlation coefficient of 0.8 for BanLec and 0.95 for RCA120. The ELLSA method demonstrated multiple advantages, such as reliability and convenience for high-throughput analysis; it also required less lectin and yielded more consistent results. As such, ELLSA proved to be a useful tool for profiling microbial glycan structures or testing novel lectins.Supplementary material: [https://cherry.chem.bg.ac.rs/handle/123456789/4888

Značaj ekto i endoparazita u patologiji autohtonih vrsta domaćih životinja na zajedničkim pašnjacima

Infekcije parazitima predstavljaju značajan zdravstveni problem kod životinja, posebno držanih na zajedničkim pašnjacima, gde se mešaju različite vrste životinja. Uzrokuju ih protozoe, helminti i artropode. Kolika je prevalenca i kojih sve vrsta parazita trenutno ima u Srbiji teško je reći, s obzirom na to da se ovakva istraživanja vrše sporadično. To se pre svega odnosi na autohtone vrste i rase domaćih životinja, koje nisu obuhvaćane uobičajenim merama kontrole parazita. Na osnovu povremenih ispitivanja može se, ipak, steći slika o najčešćim parazitskim infekcijama koje ugrožavaju ove vrste životinja i one će detaljnije biti opisane u daljem tekstu.Zbornik predavanj
