The crustacean coprolite Favreina prima n. sp. and its internal structure are described from an upper Frasnian–lowermost Famennian limestone clast of moderately deep water origin, which derived from an Upper Carboniferous conglomerate of the Rif Mountains, northern Morocco. The fecal pellets were produced by early decapods that may be related to the Palaeopalaemonidae. Foraminifers of the stratigraphic marker genus Eonodosaria are associated with the coprolite. This is the third report of Paleozoic crustacean coprolites and the first occurrence prior to the Lower Permian.

The paper's theme is the internal structure of the Udmurt ethnos of the 19 - early 20 centuries. An overview of the main territorial and local divisions of the Udmurts was made according to the following indicators (criteria): the language, the location of the late Udmurt burial grounds of the 16 - first half of the 19 centuries, the costume complexes, the settling (inhabiting) zones of the main clan groups. The modern ethnological definitions such as ethnographic, ethnic, territorial and local groups used to denote structural elements of ethnos are given in the paper. To reveal the theme the author analyses three main directions. The first is the beliefs and rites of the Udmurts living in the 19 and early 20 centuries, the second is the problem of territories' colonization and the process of the ethnographic groups' formation, and the third is the main factors that influenced the Udmurts' formation. Within the first direction the all-Udmurt religious traits as well as the most important peculiarities of the beliefs and cult practices both of the Northern and Southern Udmurt groups are traced according to the folklore and ethnographic materials. Within the second direction the basic aspects of the colonization of four territorial groups' regions such as the Middle Vyatka River territories, the Cheptsa River basin, the southern part of modern Udmurtia, and the area between the right bank of the Lower Vyatka River and the Lower Kama River are explored according to the medieval archaeological data. The overall characteristics of the archaeological places and the results of their study, as well as the process of the population's formation at the above mentioned four regions are defined at the same time. Some poorly studied aspects of the problem under consideration are indicated. Within the third direction the four main factors for the joining process of the Udmurt ethnos formation are indicated. Among them are the common Perm base of all ethno-territorial Udmurt groups, then the long development including such sociocultural association as the Volga-Kama region, and also the consolidating functions of large district and territorial shrines, as well as the influence of the Bulgarian and Russian cultures

This is the first of three planned papers describing ZAP, a satisfiability engine that substantially generalizes existing tools while retaining the performance characteristics of modern high-performance solvers. The fundamental idea underlying ZAP is that many problems passed to such engines contain rich internal structure that is obscured by the Boolean representation used; our goal is to define a representation in which this structure is apparent and can easily be exploited to improve computational performance. This paper is a survey of the work underlying ZAP, and discusses previous attempts to improve the performance of the Davis-Putnam-Logemann-Loveland algorithm by exploiting the structure of the problem being solved. We examine existing ideas including extensions of the Boolean language to allow cardinality constraints, pseudo-Boolean representations, symmetry, and a limited form of quantification. While this paper is intended as a survey, our research results are contained in the two subsequent articles, with the theoretical structure of ZAP described in the second paper in this series, and ZAP's implementation described in the third.

Translation has probably become the dominant means of communication between European literatures and, in consequence, may be considered a privileged object of study for Comparative Literature. Yet the complex nature of translation has hardly been recognized as an interlingual as well as an intralingual and intersemiotic operation. Translation between literatures covers two possible directions and should be labelled accordingly as either ‘intranslation’ or ‘extranslation’. In order to understand the complex roles all these translation forms have played during the history of European literatures and of European interliterary contacts, an explanatory model is needed that links the study of literatures and of interliterary relations: according to systems theory, literatures are to be understood as complex networks of relations that regulate both their internal structure and relations with other systems. Examples of translation figures and of translation flows help to show how translations contribute to the establishment of macro-European literary networks.

Regularities in the distribution of rare-metal and rare-earth pegmatites within the Western and Central parts of the Ukrainian shield are determined. New geological criteria and search signs for rare-metal and rare-earth mineralization have been developed. The first group includes the forecasting criteria that are tied to the general patterns of location of pegmatites in time (geochronological) and space (megastructural). These criteria define the main structural units (pegmatites provinces, regions, districts) and their metallogenic specialization. The second group combines regional criteria among which are distinguished tectonostructural, magmatic and metamorphic. These forecasting criteria define the formation and localization of the pegmatite belts and fields. The third group consists of criteria that emerge from the conditions for the formation and localization of pegmatite nodes and bundles. The fourth group are the criteria of pegmatite bodies that can be identified during study their internal structure. These are mineralogical-geochemical, structural-textural, petrochemical, thermobarochemical and thermoluminescent. Prospects for further work aimed at identifying new rare-metal and rare-earth metal deposits within pegmatite-bearing fields are estimated.

В статье рассматривается изменение внутренней структуры горной породы под влиянием механического и криогенного воздействия. Проведены три экспериментальных исследования с гранитными образцами горных пород. Первый эксперимент показал, что механическое воздействие изменяет кристаллическую структуру гранита, а второй эксперимент полностью сходится с теорией, и показывает, что горные породы разрушаются быстрее при воздействии с высокой скоростью, чем при постоянной либо плавно повышающейся нагрузке. В третьем эксперименте образцы гранита были погружены в жидкий азот (77,4 К) и жидкий гелий (4,2 К) A change in the internal structure of the rock under the effect of the mechanical and cryogenic action is examined. Three experimental studies with the granite models of the rocks were carried out. The first experiment showed that the mechanical action change the crystal structure of granite, and the second experiment completely converges with the theory, and it shows that the rocks are destroyed more rapidly under the influence with the higher speed, than with a constant or smoothly risen load. In the third experiment the models of granite were submerged in liquid nitrogen (77,4 K) and liquid helium (4,2 K)

O gnosticismo, embora tenha raízes na filosofia grega e em experiências religiosas orientais, irrompeu no seio do cristianismo no século II, dizendo aperfeiçoá-lo e constituir-se na verdadeira Igreja. Ao reler as verdades cristãs desde sua cosmovisão, tornou-se um dos maiores perigos para a fé cristã, constituindo-se numa questão de vida ou morte para o cristianismo. Neste estudo, o autor dá uma visão geral do movimento, privilegiando a compreensão de sua estrutura interna como doutrina filosófico-religiosa. Começa por uma abordagem histórica do fenômeno para, em seguida, entrar no estudo do gnosticismo propriamente dito: o problema de suas raízes, seus padrões de pensamento ou mitos, as diferentes teorias dos gnósticos e seus componentes e características. O texto termina apresentando algumas formas modernas de gnosticismo, em suas concepções e doutrinas, bem como suas implicações para o cristianismo na aurora do Terceiro Milênio.Abstract: Having its roots in Greek philosophy and in Eastern religious practices, Gnosticism nevertheless reappears in the heart of Christianity in the 2nd century, claiming to be a better version of Christianity and the true Church. In so far asit reinterpreted the Christian truths according to its own view of the cosmos it became one of the greatest dangers for the Christian faith and a life or death issue for Christianity. In this study, the author presents a general survey of the movement, focusing, in particular, on its internal structure as a philosophical-religious doctrine. A historical overview of the phenomenon is followed by a study of Gnosticism itself: the problem of its roots, its thinking patterns or myths, the Gnostics’different theories and their components and main characteristics. The text ends by presenting some modern forms of Gnosticism in their conceptions and doctrines as well as their implications for Christianity in these early years of the Third Millennium.

Using the derivative of H Boolean functions and the e-derivativedefined by the authors as the research tools, we go deep into the internal structure of the Booleanfunction values​​, additionally,by the methods of cascade calculations and analytic combinatorics, cryptographic properties such as structural features, existence,balance and algebraic immunity of rotation symmetric H Boolean functions withdiffusibility are studied. Then we get the results that the Second Order rotation symmetric Boolean functionsare H Boolean functions,andthe results to the issues such asthe balance and algebraic immunity of rotation symmetric H Boolean functionsand the existence of the Third Order symmetric H Boolean functions are also be established.
