On the strange place of Public Art in contemporary Art Theory

Este artículo parte de la idea, ampliamente difundida, que el concepto de arte público desafía radicalmente los conceptos de obra de arte autónoma. Luego considera más específicamente, la extrañeza que la noción de que el arte público no es un territorio a disposición de la creación artística libre, por el contrario, tiene que adaptarse a las complejas y exigentes del espacio público, genera en el campo teoría del arte contemporáneo, incluso en las mentes de los críticos que, como Rosalind Krauss, de combate a las raíces esencialistas de la autonomía prevista por el modernismo y con el apoyo de los artistas frente "de lucha contra la estética"This article is part of the idea, widely disseminated, that the concept of public art radically challenges the concepts of autonomous work of art. Then considers more specifically, the strangeness that notion, that the Public Art is not a territory at the disposal of free artistic creation, on the contrary, it has to be adapted to the complex and demanding of public space, generates in field of contemporary art theory, even in the minds of critics who, as Rosalind Krauss, fought the essentialist roots of autonomy envisaged by modernism and supported the artists in front "of anti-aesthetic

a primitivist rationale for Iberian and transatlantic modernisms

UIDB/00417/2020 UIDP/00417/2020This chapter discusses the Los Pintores Íntegros exhibition curated by Ramón Gómez de la Serna (1888–1963) in Madrid in 1915. While analysing the exhibition’s significance to the introduction of Cubism in the Spanish capital, this article also discusses how Gómez de la Serna’s rationale contributes in asserting a primitivist bedrock for the show—a topic that has yet to be addressed in the literature. Bearing in mind Patricia Leighten’s insights into how an “anticolonial crisis” can be associated with the praise of African art, and the concurrent pluralisation of the political, historical and aesthetic implications in modernist uses of primitivism arising from this paradigm, I will consider Gómez de la Serna’s thought along with some of the artworks shown in the 1915 exhibition. I will particularly address works exhibited by Diego Rivera (1886–1957) on that occasion. As I hope to demonstrate, the primitivist background of Los Pintores Íntegros paved the way for intertwining the local and the cosmopolitan (1) by calling for the Europeanising of Spain via the presentation of Cubism and the inscription of Madrid in the geography of international avant-garde exhibitions; and (2) by making the values of local folk art and popular culture interchangeable under the umbrella of Cubism, a process that, I will claim, encompassed the Spanishisation of the Cubist repertoire presented by the “íntegros” painters just before Diego Rivera fabricated an alternative primitivist myth of origins, grounded in Mexican ethnicity and culture.publishersversionpublishe

Identity and Politics in Eduardo Viana’s Olhão Landscapes

UIDB/00417/2020 UIDP/00417/2020This article studies the early 1920s Olhão views painted by Eduardo Viana (1881–1967). It analyses Viana’s turn to Algarvian-Mediterranean landscapes, while considering the emergence of Olhão as the Portuguese “cubist village” rendered just before its regionalisation by the fascist cultural industry. I contend that Viana’s vistas stem from his cosmopolitan profile and earlier avant-garde experiences, suggesting also that Olhão’s Mediterranean “cubist”- built environment offered Viana the prospect of a denationalised geography. The relationship between identity, place and politics will therefore be discussed.publishersversionpublishe

Distance and Distortion: Amadeo Souza Cardoso\u27s and Joan Miró\u27s War-years Painting and the Words that Fail Them

This essay considers art historical discourses on the work produced during the First World War by two painters born and living in the Iberian Peninsula: the Portuguese Amadeo de Souza Cardoso (1887–1918) and the Catalan Joan Miró (1893–1983). It considers the dialogues and relations maintained by these painters in their war-affected national artistic milieus and with the equally disrupted, international avant-garde circles, while discussing historiographical biased assumptions about production-places and their meanings, namely how localness was read as expressing isolation, distance, and lack of aesthetic significance

Development of a low-cost, non-enzymatic glucose sensor based on copper nanoparticles and laser-induced graphene towards wearable sensing

According to the International Diabetes Federation (IDF), in 2021 approximately 537 million adults (20 to 79 years) suffered from diabetes, which corresponds to a total of 10.5 % of the world’s adult population, and its prevalence is predicted to rise dramatically in the following years. Since glucose sensors constitute an effective approach for diabetes management, by providing precise information about glucose levels, the glucose sensor market has experienced enormous growth in the last few years. However, due to the high cost of the commercially available glucose detection solutions and since the rise in the number of diabetic patients has been more pronounced in low and middle-income countries, there is a high demand for low-cost glucose monitoring systems. In order to address the lack of inexpensive glucose sensors issue, this thesis aims to meet the presented necessity in three strands: the development of a glucose sensor based on copper nanoparticles (CuNPs) and Laser-Induced Graphene (LIG), fabricated on paper substrate. Firstly, the LIG technique offers a rapid and simple method for the production of graphitized material, which is an extremely conductive composite and valuable for the sensing field, without the need for expensive and complex fabrication techniques. Moreover, it allows the LIG production on paper, which is a more sustainable, flexible, economic and easily accessible alternative than other commonly used substrates. For the non-enzymatic glucose detection, a cheap copper precursor was selected for the laser-induced CuNPs formation, presenting highly catalytic activity towards the glucose oxidation. Thus, CuNPs and LIG composites were simultaneously synthesized in one fabrication step, allowing for a large-scale sensor production. LIG was fabricated with a sheet resistance value as low as 14.8 Ω sq−1. The sensor showed good glucose sensing performance (267 μA mM−1 cm−2 sensitivity, 11 μM detection limit, and high selectivity and reproducibility) with a linear range within the glucose concentration range detected in sweat (20 μM - 1.79 mM), opening the possibility of integrating this method into a wearable and non-invasive glucose monitoring system.De acordo com a International Diabetes Federation, em 2021, cerca de 537 milhões de adultos (20 a 79 anos) viviam com diabetes, o que corresponde a um total de 10,5 % da população adulta a nível mundial, e prevê-se que a sua prevalência continue a aumentar. Uma vez que os sensores de glucose constituem uma abordagem eficaz para o controlo da diabetes, fornecendo informação precisa sobre os níveis de glucose, o seu mercado tem vindo a registar um enorme crescimento. Contudo, devido ao elevado custo das soluções propostas e, uma vez que o aumento do número de pacientes diabéticos é mais pronunciado nos países de baixo e médio rendimento, continua a haver uma grande procura por sistemas de baixo custo para a monitorização da glucose. Com o objetivo de apresentar uma solução viável e barata para a deteção da glucose, esta tese visa satisfazer a necessidade apresentada em três vertentes, com o desenvolvimento de um sensor de glucose baseado em nanopartículas de cobre (Cu NPs) e grafeno induzido por laser (GIL), fabricado em substrato de papel. Em primeiro lugar, a técnica de GIL oferece uma forma rápida e simples para a produção de material grafítico, de elevada condutividade, sem a necessidade da aplicação de técnicas de fabricação dispendiosas e complexas. Além disso, permite a produção de GIL em papel, constituindo uma alternativa mais sustentável, flexível e económica do que outros substratos geralmente utilizados. A deteção não enzimática da glucose é feita através das Cu NPs, sintetizadas a partir de um precursor de cobre barato, que possuem propriedades catalíticas. Assim, as Cu NPs e o GIL são simultaneamente sintetizados numa única etapa de fabrico, permitindo uma produção destes sensores em grande escala. Na síntese do GIL obteve-se um valor de resistência da folha de 14,8 Ω sq−1. O sensor demonstrou um bom desempenho na deteção da glucose (sensibilidade de 267 μA mM−1 cm−2, limite de deteção de 11 μM e alta seletividade e reprodutibilidade) com alcance linear dentro da janela de concentrações de glucose detetadas no suor (20 μM - 1,79 mM), abrindo a possibilidade de integração deste método num sistema de monitorização de glucose "wearable"e não-invasivo

O artesanato urbano e sua relação com o artesanato tradicional e o design

Numa sociedade em constante mudança, onde a globalização influencia no nosso quotidiano e traz o desejo individual de estar sempre em mudança. É nesse contexto actual que surge a importância de entender as actividades que surgem do povo e que ao se unir à arte e ao trabalho manual transformam-se em uma nova referência como resposta às nossas necessidades. A área de estudo visa investigar o impacto do trabalho manual, aqui referido como artesanato urbano, em um âmbito português.In a society in constant change, the globalization influences our everyday lives and brings the individual desire to be always changing. In this actual context arises the importance of understanding the activities that arise from people and that by joining the art and the manual work to become a new reference in response to our needs. This study aims to investigate the impact of manual work, here referred as urban craft in a Portuguese context

Do artesão ao design de autor como metodologia

A emergência de novas metodologias de design, aliadas ao artesanato como forma basilar de reivindicação de um património material e imaterial, tem vindo a assumir um papel preponderante nas novas linguagens de design contemporâneo. As reflexões manifestam simultaneamente a transferência de um conjunto de valores outrora com carácter mais funcional, hoje numa perspectiva de comunicação onde a parte emociona se assume como factor de revelação primordial. Paralelamente, podemos também entender o papel similar das metodologias design/artesanato que se tem vindo a transferir em metodologia de design de autor, próximas das tecnologias de prototipagem rápida.The emergence of new design methodologies, combined with handcraft as a fundamental form of claiming a tangible and intangible heritage, has been assuming a leading role in the new contemporary design languages. The reflections reveal simultaneously the transfer of a set of values once with a more functional perspective, today in a communication perspective where the emotional part is assumed as a factor of primordial revelation. In parallel, we can also understand the similar role of design/handcrafts methodologies that have been transferring into an author design methodology, close to rapid prototyping technologies

Exploring motor neuron degeneration in ALS - prevention by glycoursodeoxycholic acid and signaling to microglia

Dissertação para obtenção do Grau de Mestre em Genética Molecular e BiomedicinaAmyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that affects mainly motor neurons. Neuronal pathology involves glial cells, in particular microglia. However it is not known how these cells interact with motor neurons. This is particularly important because till now no therapy has shown efficacy in ALS treatment. Here, we aim (i) to evaluate the suitability of NSC-34, a hybrid cell line of neuroblastoma and motor neurons, as a model of ALS, (ii) to explore the reactivity of microglia to the neuronal released factors and (iii) to assess the efficacy of glycoursodeoxycholic acid (GUDCA), which already has shown beneficial effects in several neurodevelopmental and neurodegenerative diseases. For that, we used NSC-34 cells transfected with human superoxide dismutase 1 (hSOD1), either wild type or mutated in G93A and the microglial N9 cell line. We observed mitochondrial dysfunction, energy impairment, NO production and metalloproteinase-9 activation, with consequent apoptosis in NSC-34/hSOD1G93A cells after 4 days of differentiation, in comparison to NSC-34/hSOD1wt cells. In addition, we established GUDCA as an anti-apoptotic and anti-inflammatory agent, able to prevent all the above mentioned features. Finally, released neuronal factors induced N9 microglia apoptosis and decreased their phagocytic ability. Overall, our results emphasize NSC-34/hSOD1G93A cells as a good ALS model, highlight GUDCA as having beneficial effects and point to microglia neuroprotective failure as a determinant mechanism of ALS pathogenesis.Fundação para a Ciência e Tecnologia - PTDC/SAU-FAR/118787/2010, entitled “Are microglia a new potential target in amyotrophic lateral sclerosis (ALS)?” to DB and PEst- OE/SAU/UI4013/2011 to iMed.U
