The study focuses on the development path of a tourism destination area centered around a special nature reserve and adjacent rural communities in the northern part of Serbia. Utilizing evolutionary economic geography (EEG) as an increasingly present theoretical and conceptual framework in the studies of tourism, this research project employs key EEG concepts of ‘path dependence’ and ‘co-evolution’. ‘Path dependence’ examines different social, economic, institutional and sectoral factors that direct, propel and/or hinder destination development, while ‘co-evolution’ analyzes causal and relational exchanges of stakeholders within and associated with the destination. The objective of this study is to trace developmental and relational trajectories of the nature reserve, tourism enterprises in its vicinity, and the place and role of public sector in these processes. The study, therefore, aims to analyze: (1) how the concept of ‘path dependence’ applies to the tourism development path of the nature reserve; (2) the dynamics of co-evolutionary and relational exchange processes in the nature reserve destination area, namely those occurring between actors operating in both public and private sectors. The two combined EEG approaches, previously not applied within the outlined geographical context, serve to illustrate and explain overall development mechanisms within a tourism destination, relevant economically, socio-culturally as well as environmentally for its region and on the tourism market of Serbia. When methodology is concerned, the study is in form of a case study, with primary data drawn from semi-structured, in-depth interviews and supported with complementary data from relevant scientific articles, government documents, web sites and other publications. The study findings show that the nature reserve in its tourism growth displays a path dependence determined by two seemingly diverging factors: (1) rules and regulations pertaining to protected areas such as nature reserves dictate tourism development and (2) the reserve management entrepreneurial skills play a noteworthy role in shaping its tourism growth. Apart from path dependence, the tourism development path associated with the nature reserve displays path plasticity, which represents a new direction in tourism growth based on the existing infrastructural and managerial framework. Moreover, the study outcomes indicate that levels, directions and intensity of co-evolutionary and relational exchanges among all stakeholders included demonstrate several different patterns. While there is detectable relationship between the nature reserve and most local tourism-related stakeholders, relationships among local stakeholders themselves are rather uneven. Similar patterns are found regarding the involvement of public sector. Public sector is closely linked with the nature reserve, however, its association with other tourism stakeholders in the destination area is uneven.  These findings support the idea that each destination area stands as a unique and complex entity, with various endogenous and exogenous factors shaping its growth.

<p>Specijalni rezervati prirode &quot;Gornje Podunavlje&quot;, &quot;Karađorđevo&quot;, &quot;Koviljsko - petrovaradinski rit&quot;, &quot;Obedska bara&quot;, i &quot;Stari Begej - Carska bara&quot; predstavljaju upečatljive primere vlažnih stani&scaron;ta Vojvodine. Raznovrsni prirodni resursi predodredili su ove prostore za privredni razvoj u okviru &scaron;umarstva, ribarstva, lovstva, ali i turizma. Sve to proizvodi&nbsp; snažan pritisak na za&scaron;tićene ekosisteme. Intenzivni uticaji na ove prostore realizovani su i u pro&scaron;losti, pre progla&scaron;enja za&scaron;tite. Zbog svega, ovo je pravi momenat da se počne razmi&scaron;ljati o njihovom održivom kori&scaron;ćenju, kako bi i buduće generacije mogle, u istoj ili većoj meri, da koriste resurse specijalnih rezervata prirode. Održivi razvoj bi mogao bitno da pomogne proces za&scaron;tite prirode koja je od su&scaron;tinskog značaja za ova vlažna stani&scaron;ta.</p> / <p>Special nature reserves &quot;Gornje Podunavlje, &quot;Karadjordjevo&quot;, &quot;Koviljsko - petrovaradinski rit&quot;, &quot;Obedska bara&quot;, and &quot;Stari Begej - Carska bara&quot; present outstanding examples of wetlands in Vojvodina. Diverse natural resources have earmarked these areas for economic development within forestry, fishing, hunting and tourism. All of these activities have protection of nature has been declared. Because of all this, it is the right moment to start thinking about using special nature reserves sustainably, so as to let future generations use their rosources to a greater extent. Sustainable development could significantly help the process of the protection of nature, which is of essential importance for these wetlands.</p>

We present the first high-resolution X-ray spectrum of a putatively single Wolf–Rayet (WR) star. 400 ks observations of WR 6 by the XMM-Newton telescope resulted in a superb quality high-resolution X-ray spectrum. Spectral analysis reveals that the X-rays originate far out in the stellar wind, more than 30 stellar radii from the photosphere, and thus outside the wind acceleration zone where the line-driving instability (LDI) could create shocks. The X-ray emitting plasma reaches temperatures up to 50 MK and is embedded within the unshocked, “cool” stellar wind as revealed by characteristic spectral signatures. We detect a fluorescent Fe line at ≈6.4 keV. The presence of fluorescence is consistent with a two-component medium, where the cool wind is permeated with the hot X-ray emitting plasma. The wind must have a very porous structure to allow the observed amount of X-rays to escape. We find that neither the LDI nor any alternative binary scenario can explain the data. We suggest a scenario where X-rays are produced when the fast wind rams into slow “sticky clumps” that resist acceleration. Our new data show that the X-rays in single WR star are generated by some special mechanism different from the one operating in the O-star winds.

Title: Educational projects focused on the area of Milíčov forest and ponds. This graduation thesis deals with project education in the field of natural monument Milíčov forest and ponds. It directly borders with southern city housing estate. Result of this work is a collection of materials focusing on environmental education and upbringing pupils on 2nd stage of basic schools, which are located near this monument. These are mainly a methodology for teachers, manual to the project education, worksheets for pupils and creative solution of worksheets for teachers. The starting point for creating projects has been a partial study, questionnaire and open discussion with students. Teoretical part at its beginning describes general conservation and special nature protection, to place issues in a boarder context. The historical aspect is also mentioned. In the thesis are also defined Milíčov forests and ponds characteristics, taking into account their rarities. It is mainly dealt with occurring of important species and specially protected species in this area. In my work is also given the emphasis on the General educational program, environmental education, analysis of schoolbooks and organizational forms of teaching. I bear on didactic theory of which I issued in projects creating. Keywords: General...
