The aim of this study was to contribute to the knowledge of Arcyptera alzonai, considered an endemic Italian species, whose biology is little known and which has an uncertain taxonomic status. Some individuals were found on a small site within its historical presence area in Susa Valley (Piedmont, NW Italy). Some recordings of the song, until today unknown, were made and analyzed. From the oscillograms obtained, no significant differences emerged with the congener species Arcyptera microptera. Also according to various authors these two species are at the moment indistinguishable from a morphological point of view. Therefore, a possible synonymy among these two taxa can be assumed which, however, must be investigated and confirmed by further research based on genetic analysis.

Abstract. The article analyzes the autobiography of the famous Russian philosopher, theologian and scientist Pavel Florensky, as well as those of his texts that retain traces of memories. According to Florensky, the personal biography is based on family history and continues in children. He addresses his own biography to his children. Memories based on diary entries are designed as a memory diary, that is, as material for future memories. The past becomes actual in autobiography, turns into a kind of present. The past, from the point of view of its realization in the present, gains meaning and significance. The au-thor is active in relation to his own past, transforming it from a collection of disparate facts into a se-quence of events. A person can only see the true meaning of such events from a great distance. Therefore, the philosopher remembers not so much the circumstances of his life as the inner impressions of the en-counter with reality. The most powerful personality-forming experiences are associated with childhood. Even the moment of birth can decisively affect the character of a person and the range of his interests. The foundations of a person's worldview are laid precisely in childhood. Florensky not only writes mem-oirs about himself, but also tries to analyze the problems of time and memory. A person is immersed in time, but he is able to move into the past through memory and into the future through faith. An autobi-ography can never be written to the end because its author lives on. However, reaching the depths of life, he is able to build his path in such a way that at the end of this path he will unite with the fullness of time, with eternity.

In 1792, the French Revolution became a thing in itself, an uncontrollable force that might eventually spend itself but which no one could direct or guide. The governments set up in Paris in the following years all faced the problem of holding together against forces more revolutionary than themselves. This chapter distinguishes two such forces for analytical purposes. There was a popular upheaval, an upsurge from below, sans-culottisme, which occurred only in France. Second, there was the “international” revolutionary agitation, which was not international in any strict sense, but only concurrent within the boundaries of various states as then organized. From the French point of view these were the “foreign” revolutionaries or sympathizers. The most radical of the “foreign” revolutionaries were seldom more than advanced political democrats. Repeatedly, however, from 1792 to 1799, these two forces tended to converge into one force in opposition to the French government of the moment.

The article considers and analyses the basic principles and directions of Russian foreign policy activities during the presidency of V.V. Putin from the moment of his assumption of the post of head of state to the current presidential term. The authors determine the basic principles of Russia's foreign policy in the specified period and make the assessment to them. The study uses materials from publications of both Russian and foreign authors, experts in the field of political science, history and international relations, as well as documents regulating the foreign policy activities of the highest state authorities. The paper considers the process of forming the priorities of Russia's foreign policy both from the point of view of accumulated historical experience and continuity of the internal order, and in parallel with the processes of transformation of the entire system of international relations and the world order. The article notes the multi-vector nature of Russia's foreign policy strategy aimed at developing multilateral interstate relations, achieving peace and security in the interstate arena, actively countering modern challenges and threats to interstate security, as well as the formation of a multipolar world. The authors conclude that at present, Russia's foreign policy activity is aimed at strengthening Russia's prestige, supporting economic growth and competitiveness, ensuring security and implementing national interests. Internal political reforms contribute to strengthening the political power of the President of the Russian Federation and increasing the efficiency of foreign policy decision-making.

Michel Butor, born in 1926, one of the leaders of the French New Novel movement, has written only four novels between 1954 and 1960. The most famous of them is La Modification (Second thoughts), published in 1957. The author of the paper analyzes two other Butor’s novels: L’Emploi du temps (Passing time) – 1956, and Degrés (Degrees) – 1960. The theme of absence is crucial in both of them. In the former, the novel, presented as the diary of Jacques Revel, a young Frenchman spending a year in Bleston (a fictitious English city vaguely similar to Manchester), describes the narrator’s struggle to survive in a double – spatial and temporal – labyrinth. The first of them, formed by Bleston’s streets, squares and parks, is symbolized by the City plan. During his one year sojourn in the city, using its plan, Revel learns patiently how to move in its different districts, and in its strange labyrinth – strange because devoid any centre – that at the end stops annoying him. The other, the temporal one, symbolized by the diary itself, the labyrinth of the human memory, discovered by the narrator rather lately, somewhere in the middle of the year passed in Bleston, becomes, by contrast, more and more dense and complex, which is reflected by an increasinly complex narration used to describe the past. However, at the moment Revel is leaving the city, he is still unable to recall and to describe the events of the 29th of February 1952. This gap, this absence, symbolizes his defeat as the narrator, and, in the same time, the human memory’s limits. In Degrees temporal and spatial structures are also very important. This time round, however, the problems of the narration itself, become predominant. Considered from this point of view, the novel announces Gerard Genette’s work Narrative Discourse and his theoretical discussion of two narratological categories: narrative voice and narrative mode. Having transgressed his narrative competences, Pierre Vernier, the narrator of the first and the second parts of the novel, who, taking as a starting point, a complete account of one hour at school, tries to describe the whole world and various aspects of the human civilization for the benefit of his nephew, Pierre Eller, must fail and disappear, as the narrator, from the third part, which is narrated by another narrator, less audacious and more credible.

Crimes against marriage and family are a particular group of social relation­ships that the law has defended properly in view of the high public significance and value they enjoy. At the moment they are regulated in Chapter VI, Section I, of the specific part of the Penal Code the Repub­lic of Bulgaria. The subject matter of this Statement will, however, be the legisla­tive provisions concerning these criminal­ized acts in retrospect. The purpose of the study is to show by historical method and through the comparatively legal method the development of these criminal groups during the periods of various criminal laws in Bulgaria. This will also provide a basis for reflection on possible de lege ferenda proposals. This report from a structural point of view will be divided into three distinct points, marking each of the penal laws in the Republic of Bulgaria, which were in force before 1968.

AbstractCtenophthalmus is considered the largest genus within the Order Siphonaptera. From a morphological point of view, only males of this genus can be identified at species and subspecies levels using morphological keys, whereas there are no morphological criteria in order to classify females at these taxonomical levels. Furthermore, the amount of available molecular and phylogenetic data for this genus is quite scarce so far. The main objective of this work was to assess the utility of the combination of nuclear and mitochondrial markers with respect to their ability to differentiate among different subspecies within the Ctenophthalmus genus. With this purpose, we carried out a comparative morphological and molecular study of three different subspecies (Ctenophthalmus baeticus arvernus, Ctenophthalmus nobilis dobyi, and Ctenophthalmus andorrensis catalaniensis) in order to clarify and discuss its taxonomic status. In addition, our study complemented the molecular data previously provided for Ctenophthalmus baeticus boisseauorum and Ctenophthalmus apertus allani subspecies. We sequenced five different molecular markers: EF1-α, ITS1, ITS2, cox1, and cytb. Our results confirmed that morphological data by themselves are not able to discriminate among Ctenophthalmus female taxa; however, the combination of the nuclear marker EF1-α together with mtDNA markers cytb and cox1 constituted a useful taxonomical and phylogenetic tool to solve this issue. Based on these results, we consider that the use of this molecular approach should be gradually used within Ctenophthalmus genus in order to complement its classical taxonomy and clarifying the complex taxonomy of other congeneric species of fleas.

There are many developed strategies for evaluating emulsion stability, aimed at determining the life circle of emulsions. Most of them are based on rheological properties of emulsions. There are, however, very few based on direct emulsion observations. In this paper we present a developed method for the emulsion stability evaluation by direct observation of optical emulsion properties. We propose the fractal dimension approach as a stability quantification measure. The method is based on the measure of emulsion transmittance properties, which are directly dependent on the emulsion stability at the moment of measurement. The oil in water emulsion was used as a test emulsion. The system is classified as stable emulsion and our intention was to find the moment when it starts to break. Emulsion transmittance properties were measure applying a system for acquisition of visual information, which is based on a CCD camera and a fast PC configuration equipped with the capturing software. The acquired sets of visual information were analyzed by the OZARIA software package. The fractal dimensions were determined by the box counting method. For these experiments, 100 boxes of different sizes were used. Experimental emulsions were measured after 7, 14, 21 and 28 days from the moment of creation. A slight increase in fractal dimensions was observed, which indicates that the emulsions are still in the stable region, or from the fractal point of view emulsion are still regular and no significant irregularities were observed. From the first experiments the applied methodology proved to be sensitive enough to be used for emulsions stability evaluation.

In order to improve the energy performance of buildings, the need to value economically investments of energy efficiency associated with the rehabilitation of dwellings arises. This point of view provides an useful tool for analysts who start in the economic appraisal of energy efficiency investments. The present research gives a conceptual framework for the economic assessment of these types of investments in dwellings. As a result, it is possible to identify two techniques in the appraisals of this nature: dynamic and static approaches. Both methods contrast the benefits (energy savings) with the costs of investments over time. However, they differentiate the opportunity and the moment when investment must be carried out given an uncertainty scenario. This conceptual precision allows the study of several publications where different alternatives in retrofitting houses where evaluated, confirming the considerations that must be taken into account when economic modelling is made: the type of approach to be used (dynamic or static) and; at the definition of the investment alternatives and scenarios, the aspects of time, irrevocability and uncertainty.ResumenEn pro de la mejora del desempeño energético de los edificios, surge la necesidad de evaluar económicamente las inversiones de eficiencia energética asociadas a la rehabilitación de viviendas. Este punto de vista trata de ser una herramienta útil para analistas que se inicien en la evaluación económica de inversiones en eficiencia energética. La presente investigación muestra un marco conceptual de la evaluación económica de este tipo de inversiones en viviendas. Como resultado, es posible identificar dos enfoques presentes en los análisis económicos de esta naturaleza: el dinámico y el estático. Ambos métodos contrastan los beneficios (ahorros energéticos) con los costes de las inversiones en el tiempo. Sin embargo, diferencian la oportunidad y el momento en que la inversión debe realizarse dado un escenario de incertidumbre. Esta precisión conceptual permite estudiar varias publicaciones donde se evaluaron diferentes alternativas de reacondicionamiento en viviendas, confirmándose las consideraciones que deben tenerse presentes en momento de realizar la modelación económica: el tipo de enfoque a usar (dinámico o estático) y, en la definición de las alternativas de inversión y escenarios, los aspectos de tiempo, irrevocabilidad e incertidumbre.

The subject of the research is the criminal community, its characteristics, and features within the framework of criminology. The purpose of the research is to confirm or disprove hypothesis that a criminal community as a criminological phenomenon is nor equal to a criminal organization or an organized criminal group Methodology. The author uses general theoretical methods (comparative analysis, generalization, deduction) and specific methods (formal legal interpretation of legal acts, questionnaires). The main results, scope of application. A criminal organization and a criminal community are different criminological phenomena that differ from each other in significant ways. The differences are both in the degree of criminal organization, and the complexity of the structure of internal and external interaction. From the point of view of a systematic approach, a criminal community is not only a more complex system compared to a criminal organization. It is characterized by an improved structure of internal interaction, in which the hierarchical structure is either complicated, or replaced or supplemented by a network structure. The peculiarity is to complement the system approach with a synergistic one: in the criminal community, the pooling of criminal efforts is carried out more effectively, mainly in the sphere of external relations. The criminal community is a more open system compared to the criminal organization. Certain features can be identified in the contacts of criminal community members with the external environment. The most important feature is a symbiosis of criminal and legal practices that affects the life of entire regions or relatively large masses of the population. The criminal community is a purposeful system with its own specifics. And this specificity is seen in the fact that the criminal community pursues (secretly or openly, at the moment or in the foreseeable future) the achievement of political goals, namely: the possession of power, infiltration into power, undermining power, its capture and retention. It is power, not wealth, that is the real goal of the criminal community, and not just because it is easily converted into wealth. Power is valuable in itself, because it also gives a lot of other advantages. Conclusions. A criminal community cannot be reduced to a criminal organization, much less – to an organized criminal group, and this conclusion requires to be included into legislation.

Resumo: Neste trabalho buscamos realizar uma breve genealogia – sempre inacabada – acerca das formas como a política – especificamente sua dimensão militante e engajada – se manifesta no cinema, a partir de um recorte histórico que privilegia a produção militante e coletiva dos anos 1960 e 1970. Nesse período vários coletivos e iniciativas individuais surgiram em torno de um cinema engajado. Ao recuperar algumas dessas iniciativas, é possível retomar também as questões que elas abordavam, tais como o ato de delegar a câmera ao trabalhador, as relações entre as imagens filmadas num momento de urgência – o ponto de vista – e sua articulação na montagem, o modo de distribuição dos filmes militantes. Assim, percebemos o quanto esse momento de contestação política será também o de uma invenção formal no âmbito do cinema.Palavras-chave: cinema militante; cinema coletivo; contra-informação.Abstract: In this paper we seek to develop a genealogy – always unfinished – about the ways in which politics – specifically in its militant and engaged dimensions – manifests itself in cinema, throughout a historical frame that privileges the militant and collective production from the sixties and the seventies. During this period, several collectives and individual initiatives emerged regarding an engaged cinema. By recovering some of these initiatives it is possible to also recapture the issues that they addressed, such as the act of delegating the camera to the workers, the relations between the images made in moments of urgency – the point of view – and its assemblage in montage, the modes of distribution of the militant films. Therefore, we realize that the moment of political challenge will also be of formal invention in the scope of cinema.Keywords: militant cinema; collective cinema; counter-information.
