Mobile Access to Cultural and Historical Heritage Web Pages

The main focus of attention in this paper is the access to websites of leading regional, national and world museums. Their accessibility from desktop and mobile devices is hereby evaluated. The paper covers a detailed analysis of the mobile operating systems, their market share in Bulgaria and the opportunities they offer to the users. The need for contemporary cultural and historical heritage websites which maintain lighter but fully-functioning mobile versions, facilitating and making their access from portable devices easier, is also well-grounded here

Mobile Applications for Cultural and Historical Places

A review of free applications of smartphones working under the operation system of Android is made in the paper. The applications present users information about historical and cultural places of interest at travelling. There are three main groups of applications subject of discussion in the paper – world, national and regional. Their abilities, positive and negative characteristics are compares and described. A conclusion can be made that there is a necessity of new application that presents tourists detailed information about the Old capital of Bulgaria

Mobile Applications for Cultural Tourism – Past, Present, and Future. Criteria for a Successful Mobile App

This publication presents a prototype of a mobile application for cultural tourism. Its main goal is to provide information about tourist sites in a city with a rich historical past and deeprooted traditions, catering to the needs and preferences of contemporary users in terms of functionality and user-friendliness. The paper analyzes contemporary Bulgarian and foreign mobile applications for cultural tourism, emphasizing their advantages over similar applications that were active in the recent past. These advantages include availability, interactivity, and an enhanced user experience. The purpose of the paper is to develop and promote a mobile application that will meet the needs of tourists. The methodology for designing the prototype includes a review and comparative analysis of mobile applications that existed a decade ago, as well as current applications in this field in 2023. Both local applications for Bulgaria and international applications for the Czech Republic, Greece, Italy, Hungary, and Spain were studied. The study focused on usability and other key characteristics that are similar to the functionality of the developed application. Weaknesses of some of the analyzed applications and problems avoided in the proposed prototype are indicated. The paper also presents the primary features of the developed application, such as its user-friendliness, speed of operation, intuitive design, and easy access to tourist and cultural sites. In the future, with the introduction of various mobile applications in this field, it is expected that users will be greatly facilitated in their search for up-to-date information on cultural and historical sites around the world

Long Distance Migration of Beluga (Huso huso) and Stellate Sturgeon (Acipenser stellatus) in Lower Danube River in Relation with Iron Gate II Dam

Construction of the dams in Lower Danube River (LDR- rkm 0 Sulina – rkm 1075 Baziasi) without fish passages, as well as illegal fishery and river bottom modification due to navigation had negative impact on sturgeon’s populations. Beluga Sturgeon, Stellate Sturgeon and Russian Sturgeon still migrate to spawn in LDR but there is lack of information relating to sturgeons long distance migration in this area. Tagging with Vemco V16 TP acoustic tags, equipped with temperature and depth sensors involved 36 adult Beluga and 44 Stellate Sturgeons provide new data about sturgeon migration. Their migrations are monitored by VR2W receivers, deployed on between rkm 71 and rkm 864. Analysis of data showed that 17% of Beluga and 30% of Stellate Sturgeon never recorded and 30% and 11% of Beluga and Stellate Sturgeon recorded in period more than 30 days after tagging. Only 5% of Beluga and 7% of Stellate Sturgeon have been recorded after a period of more than 1 year. During 2013-2016 4 adult Beluga and 1 adult Stellate Sturgeon were recorded in the IGII Dam area. Results of this investigation showed that sturgeons still approached the IG2 dam and construction of fish passage on this dam is needed

The travelling graves: memorial Jewish cemetery in Zrenjanin

Jevrejsko groblje u Zrenjaninu (nekadašnjem Velikom Bečkereku i Petrovgradu) otvoreno je 1828. godine i do danas je u dva navrata bilo premeštano sa jedne na drugu lokaciju. Prilikom poslednjeg izmeštanja 1986. godine, koje je bilo praćeno brojnim propustima i skandalima, nije sačinjen popis sahranjenih lica. Uz kratak istorijat seoba jevrejskog groblja i opis današnje lokacije, u radu su predstavljeni rezultati višemesečnog istraživačkog rada kojim se ova greška nastojala ispraviti. Pored mape samog groblja sa izrađenom sistematizacijom nadgrobnih spomenika, data su imena svih pokojnika u izvornoj (nemačkoj i mađarskoj) i srpskoj ortografiji, kao i topografska oznaka njihovog spomenika u okviru groblja.The Jewish Cemetery in Zrenjanin (previously named Veliki Bečkerek and Petrovgrad) was opened in 1828, and has, in the meantime, been twice moved from one location to another. At the time of the most recent replacement, in 1986, which was accompanied by numerous weaknesses and scandals, no evidence was made of persons buried there. Along with a brief history of dislocation of the Jewish cemetery and a description of the present location, the paper presents the results of several months of research aimed at correcting this wrongdoing. The paper presents the layout of the cemetery itself and systematization of the grave-stones, listing the names of all those buried there in the original (German and Hungarian) and Serbian orthography, as well as the topographic markings of their grave-stones within the cemetery

A recent record of Romanogobio antipai (Actinopterygii, Cyprinidae, Gobioninae) from the Danube River in Bulgaria

The Danube delta gudgeon, Romanogobio antipai, has been considered to be extinct because there were no reliable recent observations. The latest record confirmed by a voucher specimen dating from 1992. We report here on a specimen of R. antipai collected in 2016 in the Bulgarian sector of the Danube main stream using a bottom drift net at a depth of 8 m. The species determination is supported by morphological examination including discriminant and cluster analyses in comparison with three syntypes and five non-type specimens of R. antipai, samples of the R. kesslerii species complex and R. vladykovi. Romanogobio antipai most clearly differs from both R. kesslerii and R. vladykovi by proportional measurements (caudal peduncle depth, head width, eye horizontal diameter, and interorbital width), from R. kesslerii also by the number of scales above and below the lateral line (6 and 4, respectively, (vs. commonly 5 and 3), and from R. vladykovi, also by 8½ branched dorsal-fin rays (vs. 7½) and the vertebral caudal region longer than the abdominal vertebral region (abdominal+caudal vertebrae 19+21 or 20+21, vs. commonly 20+20 or variants with a caudal region shorter than the abdominal one). The possibility that R. antipai represents a deep-water cophenotype of either R. kesslerii or R. vladykovi, cannot be excluded. The new record demonstrates that R. antipai is still extant in the lower Danube but may be restricted to greater depths in the main channel and the deltaic branches
