Automatic devices for monitoring environmentally induced auto-oxidative degradation of artistic materials in conservation sites

This paper describes an automatic device for in situ and continuous monitoring of the ageing process occurring in natural and synthetic resins widely used in art and in the conservation and restoration of cultural artefacts. The results of tests carried out under accelerated ageing conditions are also presented. This easy-to-assemble palm-top device, essentially consists of oscillators based on quartz crystal resonators coated with films of the organic materials whose response to environmental stress is to be addressed. The device contains a microcontroller which selects at pre-defined time intervals the oscillators and records and stores their oscillation frequency. The ageing of the coatings, caused by the environmental stress and resulting in a shift in the oscillation frequency of the modified crystals, can be straightforwardly monitored in this way. The kinetics of this process reflects the level of risk damage associated with a specific microenvironment. In this case, natural and artificial resins, broadly employed in art and restoration of artistic and archaeological artefacts (dammar and Paraloid B72), were applied onto the crystals. The environmental stress was represented by visible and UV radiation, since the chosen materials are known to be photochemically active, to different extents. In the case of dammar, the results obtained are consistent with previous data obtained using a bench-top equipment by impedance analysis through discrete measurements and confirm that the ageing of this material is reflected in the gravimetric response of the modified quartz crystals. As for Paraloid B72, the outcome of the assays indicates that the resin is resistant to visible light, but is very sensitive to UV irradiation. The use of a continuous monitoring system, apart from being obviously more practical, is essential to identify short-term (i.e. reversible) events, like water vapour adsorption/desorption processes, and to highlight ageing trends or sudden changes of such trends.

Bini Customary law of inheritence : a shift in Igiogbe as a case study

Igiogbe cultural heritage has existed since the founding of Bini kingdom without any controversy; however since the Supreme Court decision in Idehen v Idehen the issue of Igiogbe has assumed new dimensions. Igiogbe - the house in which a Benin man lived and died devolves on his first son absolutely; but since the beginning of 20th century litigation as to the real meaning of Igiogbe and who is entitled to inheritance thereof began to increase. Controversies and increase in litigation over Igiogbe has occasioned a shift in the practice, the Bini’s are not conscious of some of these changes, most of them (Bini’s) still claim Igiogbe practices is rigidly adhered to. This study on Igiogbe inheritance in Bini kingdom is therefore carried out with a view to bringing out the changes in Igiogbe cultural practice using legal and anthropological tools to examine the changes. While laying the foundation for the discussion on the main research object the researcher examined the origin and status of customary law in Nigeria. There after I examined Igiogbe inheritance in Bini kingdom. Igiogbe and the issue of first son were critically analyzed with the aid of the research questions bringing out the changes in Igiogbe concept from traditional practice to modern practice. Study shows Igiogbe practice is still relevant in modern Bini kingdom, however, the shift and changes in practice of this cultural milieu has lead me to ask some fundamental questions which I intend to answer in the broader research work in future.

Vilhelm Ekelund och den fransk-italienska kultursfären : Några nedslag i de tidiga prosaverken - från Antikt ideal (1909) till Attiskt i fågelperspektiv (1919)

Vilhelm Ekelund och den fransk-italienska kultursfären: Några nedslag i de tidiga prosaverken – från Antikt ideal (1909) till Attiskt i fågelperspektiv (1919). (Vilhelm Ekelund and the French and Italian cultural heritage: A study of his early prose – from Antikt ideal (1909) to Attiskt i fågelperspektiv (1919)). The Swedish poet, essayist and aphorist Vilhelm Ekelund was not only influenced by German literature and philosophy, he also wrote extensive literary criticism on the subject of Romance language authors. This article discusses Ekelund’s relationship to some of the most influential French and Italian writers – as it can be seen in his work during the period 1909-1919. This relationship was ambiguous: he paid homage to French authors such as Montaigne, Montesquieu, Stendhal and Comte – as well as to the Italian poet and philosopher Leopardi – but he also severely criticized such distinguished writers as Baudelaire, Rousseau and Maupassant. One conclusion of this article is that the authors praised by Ekelund all venerate the Greek and Roman cultural heritage, whereas the despised novelists and poets were, in his opinion, either too “modern” or too “feminine” – both highly pejorative adjectives in the author’s terminology. It is also noted that Ekelund’s most ferocious attacks date from the first part of the decade, before he entered a more harmonic period with the works Metron (1918) and Attiskt i fågelperspektiv (1919).

Ensamhet - gemenskap : Ett spänningsfält i Vilhelm Ekelunds författarskap

For the Swedish poet, essayist and aphorist Vilhelm Ekelund, ensamhet (solitude) and gemenskap (intellectual and spiritual community) were highly complex notions, with various and often contradictory meanings. In this article, I argue that both concepts have positive as well as negative connotations in Ekelund’s texts. Solitude can be sweet and delightful and the poet/writer may long for it, but it can also appear to him as a sordid and painful state. In the same way, life with other people may be just as difficult and complicated. I show that Ekelund as a young poet both embraced solitude as a positive notion and suffered from depressing isolation. The theme of solitude also appeared in his early prose as a heroic stance fitting for an extraordinary person. According to Ekelund, the fate of the truly gifted artist is loneliness, and he will find great difficulties connecting with people around him. In fact, he will find intellectual and spiritual community only when communicating with the great precursors – in Ekelund’s case that meant the prominent figures of Greek and Roman cultural heritage. “Modern” artists interested him only in so much as they openly venerated this classicist tradition. Ekelund may have despaired at the idea of an intellectual or spiritual community with his contemporaries; he was, nevertheless, optimistic regarding the ability of later generations to understand him. He was convinced that he did not write for people in his own time but, indeed, for posterity.

"Ungerska för rötternas skull" : Språkval och identitet bland andragenerationens ungrare i Sverige och Finland

This thesis is a comparative sociolinguistic study which describes and compares language choice among people with Hungarian background in Sweden and Finland and studies their views on the importance of the Hungarian language and Hungarian cultural heritage for identity. The future prospects of language maintenance and language shift and differences between the Swedish-Hungarians and the Finnish-Hungarians are discussed. A survey was completed among 50 Swedish-Hungarian informants and 38 Finnish-Hungarian informants during 2006. The survey was supplemented by in-depth interviews with 15 informants during 2007. The majority language, either Swedish or Finnish, is much more active in the second-generation Hungarians’ lives than Hungarian is. Hungarian is mostly used in the domain of family relations. The language choices made today are dependent on the informant’s situation during childhood, particularly the parents’ usage of the language and the ability to learn and use Hungarian, chiefly gained through contact with the parents’ mother country and other Hungarian speakers. For some informants, having Hungarian roots forms the sole foundation for belonging, while for others it is this heritage combined with the culture, the ability to use the language or specific character traits. The Hungarian background is most often seen as a treasure offering diversity in life. Finnish-Hungarians are generally more positive about their Hungarian background, have better competence in the language and a greater awareness of the culture than Swedish-Hungarians. The Hungarian language plays a central though often symbolic role. The most important conditions for minority language preservation are language competence together with the desire and opportunity to use it; whereof the largest deficit among second-generation Hungarians is knowledge of the Hungarian language. Only one-fourth of the informants have all of the conditions necessary to be able to maintain the language, which means that Hungarian is an endangered minority language in Sweden and Finland.

Argamassas do grupo escolar Augusto Severo/RN: caracterização e incidência de manifestações patológicas

The search for cultural heritage preservation should be a constant, in order to minimize the lost of historical and cultural identity of a country. As part of this cultural heritage, highlights the importance of historical buildings. For the principles of restoration are met its important to know the state of conservation and the existing materials. Given the above, this work aims to study the pathological manifestations of the mortar coating from the Grupo Escolar Augusto Severo. For this, was conducted historical survey of the building, on-site visits with visual observation, collecting samples of mortar coating and characterization through visual and laboratory analysis, XRF, XRD, TG/DTG, OM and SEM-EDS. From the observations, pathological manifestations were found as: cracks, detachment of the coating, dirt, use of inappropriate material basis of cement, efflorescence, mold and mildew and also incompatible material base of cement. It was found that the pathological manifestations were intensified due to lack of coverage in some spots and especially the abandonment of the building, that many years does not have restoration or any other type of preventive and corrective maintenance. The results of laboratory tests indicated that the mortars studied are based on lime, with calcitic nature, and siliceous aggregate, with the presence of clay in two samples. From the samples collected, two are composed of lime, sand and clay and two by lime and sand. In this regard, it is important to conduct periodic inspections and maintenance, as well as carrying out restoration with use of material compatible with the original

Ética e educação clássica: virtude e felicidade no justo meio

O presente estudo debruça-se sobre a interface do problema educativo com a problemática da ética, compreendendo a pedagogia com a arte/ciência voltada para a busca do bem educar/instruir/formar. Para tanto, o texto mobilizará conceitos da concepção ética da Aristóteles; e, na atmosfera mental da Grécia clássica, recorre-se ao termo específico grego e transdisciplinar na origem: paideia. A seguir, este ensaio procura pontuar alguns aspectos da concepção iluminista a propósito do tema, valendo-se da noção kantiana de imperativo categórico, a qual teria sido precedida pelo parecer de Rousseau, segundo o qual a vontade - e não a razão - seria a marca distintiva do gênero humano no ambiente natural. A idéia de Piaget de uma ética da reciprocidade também é aqui mobilizada. Abordando diacronicamente a temática, serão analisados conceitos de autores clássicos no debate da relação entre educação e ética, com destaque para o sentido conferido por Hanna Arendt para a autoridade como critério distintivo da relação assimétrica entre o educador (as gerações adultas de maneira geral) e os estudantes (ou as novas gerações). Arendt defende, como conceito e pressuposto operatório, a dimensão necessariamente conservadora do ato educativo: compete ao educador preservar do mundo as novas gerações e preservar o mundo das novas gerações - para que estas não destruam o suporte e o acervo cultural acumulados.

Helena de Machado de Assis; Imagens literárias e a retórica da morte da nação inconclusa

Helena is the romance of perishable and discontinuous title character denominator of a dialectic that does not consume and build the narrative by sequential fragmentation combined with episodic frame. The novel is a lightning stroke to the romantic literary project. Therefore, this study aims to find "objective" elements of the novel that would constitute a conception of literary nation proposed by Machado de Assis, as in classical writing, where women are engaged as a metaphor for the nation by a non-cultural heroism, as the example of the Greek myth of Helena, where the feminine represents a mythical image of the nation. The paper's theoretical conception of the history of Walter Benjamin, that is, that is constructed as an allegorical appeal, the conclusions about the disciplinary society of nineteenth century of Michel Foucault, the construction of the nation as a subtle game to remember and forget of Wander Miranda and the rhetoric of death and loss reflected in the speeches of the cultural heritage of José Reginaldo Santos Gonçalves, which allow you to analyze the work permeated by subjectivity and existential conflicts by Machado, who has it arranged in dialectic with the avant-garde literary romanticism and realism. In this relationship with the Greek myth of Helen, explained that characters with the nickname of Helena in Machado's work are not uncommon. As in classical Helena, Machado s Helena uses three rhetorical are the cause of the seizure of the nation. In this game of remembering and forgetting, in the daily plebiscite, Machado draw ideal images that forged our mythical past and commitment to the future. The suffering love of Helena is suffering from failure of the nation which would have led the author to the use of allegorical language, seeking a balance in the chaos generated by the opposition between cruelty and pity widespread view in an area where only left the character's confession guilt for the death. It is a simulacrum of unfinished nation, the space for the game of remembering and forgetting, while the rhetoric of negotiation of our Brazilianness

A nação pela pluma Natureza e sociedade no Museu do Índio (Rio de Janeiro, 1953-1957)

A história política do Museu do Índio, criado em 1953, no Rio de Janeiro, sob a orientação institucional do antropólogo Darcy Ribeiro, permite conhecer algumas relações sociais estabelecidas em torno de elementos da natureza no Brasil. O estudo do momento inicial na constituição deste patrimônio cultural, de sua história e das disputas que gerou, inclusive na memória, é realizado a partir da noção de coerência ilusória de uma geração de etnólogos, militares e intelectuais e da ação do Estado nacional brasileiro na década de 1950. As fontes e documentação consultadas são de natureza arquivística, jornalística e bibliográfica.

On the Origin of Cattle: How Aurochs Became Cattle and Colonized the World

Since their domestication in the Neolithic, cattle have belonged to our cultural heritage. The reconstruction of their history is an active field of research 1 that contributes to our understanding of human history. Archeological data are now supplemented by analyses of modern and ancient samples of cattle with DNA markers of maternal, paternal, or autosomal inheritance. The most recent genetic data suggest that maternal lineages of taurine cattle originated in the Fertile Crescent with a possible contribution of South-European wild cattle populations, while zebu cattle originate from the Indus Valley. Subsequently, cattle accompanied human migrations, which led to the dispersal of domestic cattle of taurine, indicine, or mixed origin over Asia, Africa, Europe, and the New World. This has resulted in their adaptation to different environments and considerable variation in appearance and performance. More recently, rational management of breeding led to international movements of sires, which again changed the global patterns of genetic diversity.
