Туристичка валоризација општине Неготин

Author(s): Ana Čučulović,Rodoljub Čučulović / Language(s): English,Serbian Issue: 3/2010

According to its physical-geographical and socio-economical characteristics, the municipality of Negotin belongs to the territories with favorable tourist potentials. In order to scientifically validate this fact, in this paper tourist valorization has been performed using quantitative-qualitative method, giving attractiveness ranking values, based on which conclusions have been made on the direction and forms of tourist potential. The results obtained from tourist valorization have shown that the hydrographic potential and fauna are rated as good (3), and have the highest general tourist value among natural resources. General values are graded as satisfactory (1.8) and the climate is graded as unsatisfactory (1.2). Valorization of anthropogenic characteristics gave the maximal general value (4) to cultural-historical objects including sacral objects - monasteries and churches and the Rajac pimnice. The Rajac pimnice have an especially high value, as they represent, for us, a unique value that can be considered in diverse ways and adjusted to tourist utilization. Based on the performed tourist valorization it can be noted that the general tourist value of the municipality of Negotin is of regional ranking, though anthropogenic potentials are of national ranking and part of them, as emphasized, are objects that are internationally important. The basic shortcoming is the low road quality leading to places of important tourist value, even though the road network is favorable, and there are also many weaknesses in the receptive tourist base. Improvement of these shortcomings would create a good image of the municipality of Negotin in continental tourism of the Republic of Serbia.

Търновският епископат и Русия XV-XVII век

Author(s): Ivan Tyutyundzhiev / Language(s): English,Bulgarian Publication Year: 0

The image of Ottoman invasion of the Bulgarian lands, the Tarnovo Patriarchate, in its capacity as the "Mother of All Bulgarian Churches", maintained international contacts throughout the Greek Orthodox world. The Patriarchate enjoyed high prestige among Orthodox Slav on account of its consistent anti-Unite stance, adopted after the Church Union of the Council of Lyons (1247). This stance differed drastically from the contradictory policy of Byzantium and the Church of Constantinople which were inclined to make compromises with the West and the Papal institution in Rome as part of an attempt to forge an alliance and oppose the invading Ottoman forces. The Tarnovo Patriarchate strongly adhered the Orthodoxy and resisted Roman Catholic attempts at penetration in the territories under its pastoral care. The Bulgarian Orthodox Church by all probability had a major role in spreading Christianity among Cumans and some Tatars in Wallachia and Moldova in the 13 th and 14 th centuries . The high status of the Head of the Tarnovo Patriarchate was borne out by the participation of Patritach Simeon in the coronation of the Serbian monarch Stephen Dusan (1331-1335) and his Bulgarian wife Elena as Tsar and Tsarina and the transformation of the Serbian Archbishopric into a Patriarchate in 1346. Around the middle of the 14th c. the Tarnovo Patriarchate was established contacts with Russia. In 1352 Patriarch Theodosius II of Tarnovo took part in the ordination of Theodorit, Metropolitan of the Principality of Galicia-Lithuania, as Metropolitan of Russia. For Russia Tarnovo was obviously an important spiritual centre holding authority over all Orthodox Slavs. At more or less the same time we encounter the appellation "Tsarigrad-Turnov" which reflected the idea of the Bulgarian capital as a "Third Rome" and "Second Constantinople". Further proof of the high status of Bulgarian clerics among Orthodox Slavs is provided by the enthronement, in the year 1375, of three patriarchs originating from Tarnovo: Euthymius (Evtimii) of Tarnovo (1375-1393), Ephraem of Pec, Patriarch of Serbia (1375-1380; 1389-1392), and Cyprian, Metropolitan of Kiev and all of Russia (1375-1406). The survey of Bulgarian-Russian spiritual ties presented above aims at correcting a view still current in historiography according to which, between the 16th and 18th centuries, church influence followed a North-South (rather than a South-North) axis. While we may assume that such a view reflects the state of affairs in the 18th century, the earlier times of Ottoman domination (15th-17th cc.) were marked by attempts on the part of Tarnovo clerical elite to take part in the most important initiative aiming to increase Russia's prestige as the only independent and most powerful Orthodox Slavonic state. Higher clerics made a point of mentioning the names of Russians monarchs in church services intended for Bulgarian Christian congregations and thus seered Bulgarian expectations of political liberation in the direction of Russia.

Угроженост акумулације ''Завој'' ерозивним процесима - Методолошки, сазнајни и заштитни аспект -

Author(s): Predrag Manojlović,Stanimir Kostadinov,Sanja Mustafić / Language(s): Serbian Issue: 1/2008

In this paper land erosion has been investigated from its temporal and spatial variability point of view. The aim of the application of contemporary soft wares and satellite observations was to create an adequate data base which allows faster and more adequate possibility for monitoring the intensity of erosive processes, as well as meaningful decision for application of different ways of anti erosive techniques of the most dangerous areas. Geomorphologic mapping of erosive processes using plane and satellite images has allowed rational planning of field observations and, at the other side very detailed establishing of the intensity of previous erosion. A new approach applied in this paper during data processing of all relevant parameters influencing erosion is based on using of software Geomedia 5.2 (Intergraph).

Ургонски кречњаци горњег барема и доњег апта ракове баре (Карпато-Балканиди, си Србија) - анализа и поређење са суседним областима -

Author(s): Velimir Jovanović,Monika Božinović,Darivojka Ljubović-Obradović,Ivana Carević / Language(s): English,Serbian Issue: 1/2010

The Upper Barremian-Lower Aptian succession is recorded from a limestone sequence that crops out in the surrounding of Rakova Bara in the Carpatho-Balkanides range in northeastern Serbia. The micropalaeontological and sedimentological studies lead to recognition of the two types of microfacies. The benthic foraminiferal association consists of Vercorsella laurentii, Rumanoloculina robusta, Praechrysalidina infracretaceae, Dictyoconus gr. arabicus, Debarina hahounerensis, Charentia cuvilieri and Pseudocyclammina lituus that confirm the stratigraphical and palaeoenvironmental connection of the microfossil assemblages with the classical Urgonian-type, shallow-water carbonate sedimentation. The association documented for the first time in the study area is considered typical of the Tethyan Realm. The stratigraphical position of the benthic foraminifera species within the Upper Barremian-Lower Aptian interval is discussed. The Urgonian Limestone's of the studied section are comparable with adjacent areas of eastern Serbia and Romanian South Carpathians.

Author(s): Dejan Šabić,Rajko Golić,Mila Pavlović / Language(s): English,Serbian Issue: 3/2010

The territory of the municipality of Mali Zvornik is, from the aspect of morphology and spatial-functional structure, a heterogeneous area. It is located in the valley of the Drina River and in hilly-mountainous part of Podrinjske mountains. The area of the municipality is 184 km², with 14076 inhabitants (2002). The importance of water resources for the development of the municipality, particularly of the hydropower plant (HPP) “Zvornik”, is analyzed in this paper. Inadequate use of hydro-energetic potential, possibilities for construction of new hydropower plants and economic reasons for their construction are also emphasized. The priorities of the development of hydraulic engineering are defined in relation to morphological and hydrological conditions. They refer to increase of power of the HPP “Zvornik” and construction of small-scale hydropower plants in hilly-mountainous part of municipality. Considering depopulation processes in the villages of Mali Zvornik, hydraulic engineering, together with agriculture, forestry, exploitation of mineral goods and tourism, can be one of the factors of demographic and economic revitalization of this area.

Author(s): Danijela Avramović,Dragan Spasić / Language(s): Serbian Issue: 3/2019

Climate change has acquired a status of a global issue in the second half of the 20th century, nowadays becoming more and more prominent. The negative effects of climate change as manifested through natural disasters are noticeable the most in forest stands and forest ecosystems. This study covers the period from 2008 to 2017, and the data included was collected from official statistical reports. The data on the following categories was collected: average annual air temperature, average annual precipitation, average annual relative air humidity, the number of disaster events, such as insect activity, plant diseases, wildfires, or climate and geological disasters, causing damage in state forests, and the scope of such damage. The aim of this paper is to analyze the said data and to use the results to determine the influence of observed climatic elements on the incidence of damage, the scope of damage, and the damage per one disaster event in Serbian state forests. This paper is significant because it represents a pioneering attempt to synthesize the influence of temperature, precipitation, and humidity on the incidence and scope of damage in state forests resulting from insect activity, plant diseases, geophysical events, and wildfires in Serbia (excluding the Autonomous Province of Kosovo and Metohija). A non-linear dependence of the influence of climate factors on damage incidence and scope has been determined.

ФИЗИКО-ХИМИЧЕСКОЕ ОБОСНОВАНИЕ ВОЗМОЖНОСТИ РАЗРАБОТОК ЛЕКАРСТВЕННЫХ СРЕДСТВ НА ОСНОВЕ ВОДНЫХ НАСТОЕВ КРЕМНЕЙ (ПРЕДВАРИТЕЛЬНЫЕ ДАННЫЕ)

Author(s): Vladimir V. Vapirov,Vladimir M. Feoktistov,Nadezhda V. Vapirova,Ani A. Venskovich / Language(s): Russian Issue: 4 (165)/2017

Physical and chemical characteristics of water infusions of flints are measured and analyzed: рН, the oxidation-reduction potential, the specific electric conductivity, and the content of silicon in the solution. The рН in solutions of water infusions of flints stays within the range of the values of this parameter approved by the normative documents for waters of drinking purposes. The values of oxidation-reduction potentials of water infusions of flints are positive and make from > 300 to < 500 mV, which shouldn’t cause any change in the oxidation-reduction potentials of the internal environment of an organism, and curative properties of these infusions can’t be connected with the Eh parameter. The content of water-soluble mineral connections and of the easily acquired orthosilicon acid in flints is very insignificant; water infusions of flints can’t change the osmotic pressure of biological liquids and be considered as essential sources of silicon for a human body.

Author(s): Jelena Kovačević-Majkić,Milovan Milivojević / Language(s): Serbian Issue: 1/2006

Plum production is one of the most developed branches of agriculture in Suvobor region, and with that characteristics, it is of crucial importance for the development of this area. Especially on southern slopes of Mt. Suvobor, there are favourable natural conditions for plum production. According to geological base (considerable areas of serpentinites) hydrogeological characteristics and regional hydrological conditions are different in various parts of Suvobor region. From sustainable development point of view, it is necessary to take into consideration the results of hydrological researches about real amounts of water, water balance and possibilities of their usage in order to improve the plum production. Water quality, according to the possible influence of serpentinites, could be a limiting factor for plum growing development. Making water objects register and estimation of water quality, favourablly contribute to improvement of this branch of agriculture.

ФОТОСИНТЕЗ И АЗОТНЫЙ МЕТАБОЛИЗМ В ЛИСТЬЯХ ПШЕНИЦЫ ПРИ НИЗКОЙ КОНЦЕНТРАЦИИ СО2 В АТМОСФЕРЕ

Author(s): Anatoly A. Ivanov / Language(s): Russian Issue: 4 (165)/2017

The purpose of this research was to study changes in photosynthesis parameters, activity of nitrogen metabolism enzymes and proline content after incubating wheat plants at a low concentration of CO2 in a sealed chamber for 10 days. Decrease of the CO2 concentration in the atmosphere was accompanied by a change in a number of photosynthetic parameters when using CO2 as an electron acceptor in the photosystem I. There was a decrease in the gas exchange rate on the plateau of the light curve, the magnitude of the light compensation point, and the intensity of light when the light curve saturates. On the contrary, when NO2 - as an electron acceptor was used, the photosynthetic parameters in the analysis of light curves of the O2 emission varied insignificantly both under natural CO2 concentration conditions and in the case of its deficiency. Consequently, with a CO2 deficit, the significance of NO2 - as an acceptor of photosynthetic electrons increased, which could lead to a change in the C/N balance in the direction of enhancing nitrogen metabolism in plant cells. This was also indicated by the increase in the activity of glutamine synthetase, the key enzyme of this pathway. The increase in the activity of nitrogen metabolism enzymes at the deficit of carbon skeletons could lead to an excess of nitrogenous compounds and the need to withdraw them from the sphere of metabolic reactions. As a result, accumulation of proline as a conditionally reserve substance was observed, the limiting concentration of which, however, depended on the proline dehydrogenase activity.

ХАРАКТЕРИСТИКА МЕСТООБИТАНИЙ И СТРУКТУРА ПОПУЛЯЦИЙ TRIGLOCHIN MARITIMA L. (JUNCAGINACEAE) В ПРИЛИВНО-ОТЛИВНОЙ ЗОНЕ ЛИТОРАЛИ БЕЛОГО МОРЯ

Author(s): Lyudmila A. Sergienko,Tamara Yu. D'yachkova,Vera I. Androsova / Language(s): Russian Issue: 2 (163)/2017

Populations of the dominant halophyte circumboreal-polar species Triglochin maritima L. found on the western coast of the White Sea, in the estuaries of the rivers (Kolezhma, Keret’) were studied. Three experimental plots located along the transect line of the coast, which differ by the type of substrate and vegetation were assessed. Different eco-coenotic conditions of the species habitat, including geomorphic shore types, wave actions, mechanical and chemical composition of the substrate, and the types of drainage were observed. The increase in some biometric and population parameters of the T. maritima plants located in the tidal zone of the open coast, on the bay coasts, on muddy-silty and sand-gravel substrates within allocated areas was revealed. These structural features allow T. maritima to adapt dynamically to the unstable conditions of existence in the tidal zone of White Sea.

Хемијска ерозија и хидролошки биланс на простору карстног платоа шушуре

Author(s): Dušan Stojadinović,Ratko Ristić,Jugoslav Nikolić,Zoran Nikić / Language(s): English,Serbian Issue: 4/2010

The karst plateau of Susure, about 4.5 km2 in surface area, is situated on the Jadovnik eastern offset, western Serbia. The plateau is a morphologic unit higher 15 m to 30 m than the surrounding terrain. The unit consists of crushed and karstified Middle Triassic limestones. Numerous hydrogeological and geomorphologic features of the plateau are attractive for visitors in this economically underdeveloped country. Rocks building up the surrounding terrain are largely peridotites. Surface streams flow neither into nor off the plateau. Atmospheric precipitations discharge to evapotanspiration and filtration underground. More than eighteen constant springs at the limestone/peridotite tectonic contact drain fracture aquifers on the karst plateau border. Measured precipitations and springflows were the input and output data for accounting water budget of an aquifer of Middle Triassic limestones in the Susure plateau.

ХИДРОЛОШКА АНАЛИЗА ВОДОТОКА У СЛИВУ СКРАПЕЖА

Author(s): Jelena Kovačević-Majkić / Language(s): Serbian Issue: 1/2008

Reasons for lack of hydrological studies in mountainous regions are: absence of hydrological measurements and the fact that measurements were not continuous. However, as mentioned areas are basic sources of fresh, unpolluted and useful water, itis necessary to carry out water regime researches and continuous measurements. Surface amount of water in Skrapež river bed was analyzed, as well as its regime and water balance. Water management problems were pointed out as well. This paper discusses problems connected to decreasing of water amount in the last 20 years of analyzed period, variations of discharge, threats to economy in periods of both low and highwater, and also points out the torrential character of the river. The possibilities of waterusage from previously unstudied Skrapež sub basins are pointed out as well. Research and utilization of these sub basins provided that high water quality is preserved, would lead to high level of solving the problems of water supply, irrigation and torrential rivers.

Author(s): Jelena Kovačević-Majkić,Milan Radovanović / Language(s): Serbian Issue: 1/2006

Ljig municipality has a dense hydrographic network, composed mostly of the streams within the Ljig River basin. However, the quantities of water in these streams are relatively small, and characterised by great irregularities during the year. Moreover,in the last ten years of the research period, there has been a noticeable decrease of water quantities. The most significant river in the area is the Ljig River (48.9 km long), which is the largest tributary of the Kolubara River. The spring of the Ljig River is situated within the territory of the municipality, while the length of the stream on this territory is 30.13 km. The most significant tributaries of Ljig are Kacer, together with its tributary Kozeljica, as well as Dragobilj with Dragobiljica (Lalinacka Reka), Zerevac and Godevac. Among all the springs in Ljig municipality, the most important is the karst spring in the village of Ba, which is considered as the main spring of the Ljig River. It is used for water-supply of the town of Ljig and the village Kadina Luka. There are many water-management problems in Ljig municipality. The most prominent are the problems of erosion, gullying streams and floods, water-supply issues, as well as insufficient water-management infrastructure.
