Modern Bulgarian nationalists aspired towards incorporating the self-identified Bulgarian lands into the Bulgarian state. The Treaty of San Stefano ending the Russo-Turkish War of 1877-78 tantalizingly achieved these so-called national ideals. Great Power diplomacy quickly diminished Bulgaria's borders and international legal status with the 1878 Treaty of Berlin, exacerbating nationalist grievances. Bulgaria would expand vast resources to restore the San Stefano borders until Balkan Communist authoritarian regimes eventually suppressed the Macedonian issue as a foreign policy subject. Sofia's policy towards its neighbor has been overdetermined by the efforts of successive Bulgarian governments to institutionalize post-communist Bulgaria's own national identity. Bulgaria's integration into so-called Euro-Atlantic structures, i.e., NATO and the EU, had been the primary strategic objective of the Bulgarian authorities since the end of the Zhivkov regime. North Atlantic community security policy aims in response to the earliest post-Cold War foreign policy crises in the Western Balkans framed the parameters of Bulgarian diplomacy. The stabilization of FYROM in 2001, followed by Bulgaria's 2007 EU accession, led to Bulgarian nationalist values become more salient in Bulgarian politics and foreign policy. Sofia-Skopje relations are a test case for the effects of Europeanization on interdependent Balkan ethno-sectarian nationalisms and state territorial institutional development.

The long-term light curves of the novalikes TT Ari, KR Aur, AM Her and MV Lyr, were compiled and analysed for solar-like cyclical behaviour. The frequency analysis showed long-term cyclical modulations of the brightness of the stars, which can be ascribed to changes of the radii of the late type secondaries in order of ${\Delta}R/R{\simeq} 10^{-4}-10^{-5}$.

Through the result of the investigation on costumes in Bulgarian regions, the main factors for the formation of Bulgarian folk costume and its kinds and history have been found out so far as follows. Alhtough varying according to the district and climate, Bulgarian folk costumes have some general features determined by the material, the pattern, the application. For women, Bulgarian costume consists of a white shirt, a single or double apron unique depending on each region(Bruchnick), a basic dress called a tunic (Soukman), and an open-tunic typed coat (saya). The main factors for the formation of Bulgarian folk costume have been under the influence of natural and environmental features and historical streams resulting from its geographical location. Bulgaria is agriculture-oriented society based on a continental climate. Accordingly, as for the classification of costumes, body-fit clothes, such as shirts and jackets which developed in Europe and fit the body shape, have featured in Bulgaria. Besides, Bulgaria was under the rule of Turk for a long time at the end of the Middle Age. Having been influenced a lot those days, its folk costume shows Turkish elements now. With geographical features, it was found that the southern area was influenced most by Turkey and Greece, and the types of folk costumes in Europe developed mainly from the northern area. The adaptation of traditional costume forms to the new cultural and progressive principles of appeal nowadays needs knowledge, as well as feeling. Finding the right measure and proportions of using old ethnic elemints in contemporary clothing is the prerequisite of successful design.

This paper deals with Slavic discourse deixis comparing Russian, Polish, Czech and Bulgarian demonstrative and personal pronouns. In general, the Slavic proximal pronouns have precedence over the distal ones. Proximal pronouns, such as Russian eto, Polish to, and Bulgarian tova, are employed more frequently and widely than their distal counterparts to, tamto and onova. The distance-neutral pronoun to in Modern Czech was also a proximal pronoun in the past. These Slavic proximal and former-proximal pronouns function as a discourse deixis marker, whereas, in most other languages, the discourse deixis is mainly a function of distal or non-proximal demonstrative pronouns. However, the Russian, Polish, Czech, and Bulgarian discourse deixis differs in distal demonstrative and personal pronouns. In general, the Polish and Czech discourse deixis does not employ the distal demonstrative pronoun tamto or the personal pronoun ono. The Russian distal demonstrative pronoun to is actively used as a discourse deixis marker, and the personal pronoun ono can also be used to refer to the preceding discourse, though it is not frequent. In Bulgarian the distal demonstrative pronoun onova is rarely used to refer to a discourse, but the personal pronoun to frequently indicates a discourse that is repeatedly referred to in a text. The discourse deixis, which is a peripheral deixis and can be both deixis and anaphora, reveals different characteristics in different Slavic languages. In Russian, where all of the proximal, distal, and personal pronouns function as a discourse deixis marker, the deixis itself plays a crucial role in distinguishing these three pronouns from each other, revealing the speaker's psychological, emotional, temporal, and cognitive proximity to or distance from a given discourse. In Bulgarian, the most analytic Slavic language, the personal pronoun is used more as a discourse deixis marker to reveal the highest givenness of a discourse, and it seems that Bulgarian discourse deixis is more anaphoric than the other Slavic discourse deixis is.

In a series of research papers, the authors have studied some of the most important models of a contemporary universities, such as: the research university, the entrepreneurial university and the digital university and construct their Generalized Net (GN) models. This paper is based on the case-studies of Sofia University, the Technical University of Munich and the University of Edinburgh. The main focus is to put the analysis of the processes of the functioning of a university which effectively integrates Information and Communication Technologies (ICT) in all university activities. A concrete example based on the process of course administration at University of Edinburgh is considered. This university is in a process of developing an integrated information system covering most of the university activities. The opportunity of using GNs as a tool for modeling such processes is analyzed as well.

The paper considers a theoretical model for the study of the process of transfer of sulfate ions in saturated porous media - mineral composites. In its turn, the model treats diffusion of sulfate ions into cement based composites, accounting for simultaneous effects such as filling of micro-capillaries with ions and chemical products and liquid push out of them. The proposed numerical algorithm enables one to account for those simultaneous effects, as well as to model the diffusive behavior of separate sections of the considered volume, such as inert fillers. The cases studied illustrate the capabilities of the proposed model and those of the algorithm developed to study diffusion, considering the specimen complex configuration. Computations show that the theoretical assumptions enable one to qualitatively estimate the experimental evidence and the capabilities of the studied composite. The results found can be used to both assess the sulfate corrosion in saturated systems and predict and estimate damage of structures built of cement-based mineral composites.

Meridian surfaces in the Euclidean 4-space are two-dimensional surfaces which are one-parameter systems of meridians of a standard rotational hypersurface. On the base of our invariant theory of surfaces we study meridian surfaces with special invariants. In the present paper we give the complete classification of Chen meridian surfaces and meridian surfaces with parallel normal bundle.

Motivated by the fact that upper solution bounds for the continuous Lyapunov equation are valid under some very restrictive conditions, an attempt is made to extend the set of Hurwitz matrices for which such bounds are applicable. It is shown that the matrix set for which solution bounds are available is only a subset of another stable matrices set. This helps to loosen the validity restriction. The new bounds are illustrated by examples.

In the spring silkworm rearing period of year 1998, some nutritional aspects were studied in the Agricultural Research Station of the Komotini town in Greece, to investigate the feeding behaviour of some Bulgarian silkworm hybrids, suitable for spring rearing, during the fourth and fifth instal under the local climatic conditions. The silkworms were fed by locally cultivated Japanese Kinriu mulberry (Morus alba L.) variety leaves. Eight Bulgarian hybrids had been used, namely Vratza-53xVratza-52, Ukraine-20xVratza-53, Super 1xHessa 2, Merefa 2xVratza 35, as well as their reciprocal crosses. The studies showed out a remarkably higher feed intake and feed utilization by the hybrids Hessa 2xSuper-1, Merefa 2xVratza 35 and Vratza-52xVratza-53. The same hybrids showed an efficient food utilization by means of daily growths cocoon shell ratio and raw silk output. In terms of food to silk conversion efficiency Hessa 2xSuper-1 hybrid gave the best results. Larval stage duration for fourth and fifth instar was not affected by feed intake and utilization. All hybrids showed a good adaptation to the local environment and their feeding performance was equal to the international existing standards. All calculated parameters were found to be around the mean values of other up to date presented results and thus considered as acceptable for the needs of the local production.
