Figuring out the untranslatable: traces of Twombly
The intertwining of languages, such as writing and visual expression, can enrich
our understanding of the translation process and also its limits and obscure areas – the
untranslatable. Visual art can therefore become a fruitful resource for an inquiry into
translation. Accordingly, an artist like Cy Twombly, one of the most literary visual artists,
can provide clues about the enigmas of translation or at least attempt to uncover them in
the form of images. Twombly includes words and phrases in his paintings with various
degrees of legibility from a great diversity of writers, along with spots and scribbles that
are not part of any code. All of this reveals a way of evoking texts and stories covering a
wide range of different cultural groups although predominantly classic.
The poet Octavio Paz recognized in Twombly the attributes of a “universal translator”.
It is also this path that we will explore and put to test in Twombly’s work but just to a
certain extent, in which the search for universality becomes a myth, impossibility, or
incomprehension. As Ricoeur says in his study on translation “we know that no universal
language can be able to reconstruct its undefined diversity” (Ricouer 2005, 45).
Twombly’s poetic dimension is probably not universal from the point of view of
a perfect language but through the vagueness of the writing in his paintings, which
leaves room for imagination and challenges the translation process. “Poetry, and not just
poetry, but nature - seasons, vegetation - all of this is transformed, translated into image”

Analysis of the Auction and Continuous Intraday Electricity Markets of the MIBEL
The scope of this work is to analyse the continuous intraday market in the Iberian Electricity Market, from its beginning in June 2018 until the end of 2020, covering energy prices, volume of energy traded, clearing agents and the influence of the different generation technologies for energy production. The results of this analysis are then compared with the results of both the day-ahead and the auction intraday markets
Conceptual progression hypothesis study about asexual reproduction and germination in plant reproduction
This work aims the understanding of how the conceptual progression on plants reproduction presents itself to the primary school students. Was made a exploratory study (Arnal et al., 2001) to select three students for the instrumental case study (Stake, 2000) and performed in-depth interviews (Arksey & Knight, 1999). From the conceptions collected was builted an Progression Hypothesis presented according to nineteen categories and three levels of conceptualisation. According to this progression hypothesis we were able to identify the obstacle in the learning process of the concept plants reproduction

Link between viral infection and autoimmunity in primary Sjögren’s syndrome: clues from lymphocytic profile and ebv antibodies
RESUMO: A SĂndrome de Sjögren primária (pSS) Ă© uma doença sistĂ©mica autoimune caracterizada pela
presença de infiltrados linfocitários nas glândulas exócrinas, predominantemente nas
glândulas salivares e lacrimais. Ocorre principalmente em mulheres, onde os rácios de
incidĂŞncia feminino/masculino estĂŁo entre 10:1 e 20:1. Mulheres com mais de 50 anos de
idade são mais afetadas. Os sintomas principais desta condição são: xerostomia (boca seca),
keratoconjuctivitis sicca (secura dos olhos com inflamação), e secura de outras superfĂcies
mucosas (pele, vagina e epitĂ©lio do aparelho respiratĂłrio). Vários vĂrus tĂŞm sido associados
Ă pSS. O vĂrus Epstein-Barr (EBV) tem sido um forte candidato para o despoletar da epitelite
autoimune presente na pSS. No entanto, nĂŁo existe um causador viral estabelecido da epitelite
autoimune em pSS. O presente estudo demonstrou um perfil linfocĂtico que indica
hiperatividade da célula B, limitação da célula Breg e alterações na célula T, nomeadamente
nas células T circulantes que possuem um fenótipo caracteristicamente folicular. Estas
alterações podem apontar para a existência de um agente viral subjacente causador de uma
resposta imune desregulada, uma vez que alterações semelhantes estão presentes num
contexto de infeção viral. De facto, pacientes com pSS apresentam uma percentagem
aumentada de soros positivos de IgG anti-EBV EA-D, que poderá apontar para o
envolvimento do EBV na pSS. Assim, é necessário mais trabalho para estabelecer um
causador viral em pSS. Para acrescentar a este estudo, mais anticorpos para antivirais podem
ser avaliados, nomeadamente, anti-citomegalovirus, anti-vĂrus T linfotrĂłpico humano, antihepatite
C entre outros. Chamamos a atenção para as cĂ©lulas T foliculares para uma possĂvel
ligação entre infeção viral e pSS. Estudos adicionais com modelos animais podem ser
cruciais na compreensão do papel destas células em ambos os contextos e identificação de
mecanismos e padrões de diferenciação similares e a falha dos mecanismos de tolerância.ABSTRACT: Primary Sjögren’s Syndrome (pSS) is a chronic systemic autoimmune disease characterized
by lymphocytic infiltration of the exocrine glands, predominantly the salivary and lachrymal
glands, leading to damage and secretory impairment. It occurs mainly in women, with ratios
of incidence female/male are between 10:1 and 20:1. Women over 50 years of age are the
most affected. The main symptoms of this condition are xerostomia (dry mouth),
keratoconjunctivitis sicca (ocular dryness with corneal damage), and dryness of other
mucosal surfaces (skin, vagina and respiratory epithelium). Extraglandular manifestations
frequently occur, especially inflammatory articular and cutaneous manifestations, as well as
less common and more serious involvement such as neuropathy, nephritis, vasculitis or
lymphoma. Several viruses have been associated with pSS. Epstein-Barr virus (EBV) has
been a strong candidate for the triggering of autoimmune epithelitis occurring in pSS. There
isn’t, however, an established viral trigger for SS autoimmune epithelitis. Our study revealed
a lymphocytic profile indicating B cell hyperactivity, Breg impairment and T cell alterations,
namely in circulating T cells with follicular-like phenotype. These changes can be attributed
to an underlying viral agent triggering an unregulated response. Indeed, pSS patients
presented a higher percentage of positive serum for anti-EBV EA-D IgG, which might point
towards a role of EBV in pSS. Still, more work is required to establish a definite viral trigger
for pSS. Adding to this study, more antiviral Abs can be assessed, namely, against CMV,
human T-lymphotropic virus (HTLV), HCV and others. We call the attention towards
follicular T cell subsets for a possible link between viral infection and pSS. More studies
using animal models can be paramount in the understanding of follicular T cells roles in both
contexts and identify similar mechanisms and differentiation patterns and a breakdown of
tolerance mechanisms
New Trends in Active Power Filter for Modern Power Grids
From harmonic compensation to interface with renewable energy sources, active filters are capable to improve power quality, increase the reliability of the power grid, and contribute to make feasible the implementation of decentralized microgrids. In this scenario, this chapter provides a discussion involving new trends on distribution power grids, with active power filters playing an important key role. Considering the aforementioned explanation, part of the chapter covers active filter applications for power grids. In sequence, we discuss time domain control algorithms to identify power quality disturbances or other problems that may compromise the power grid reliability, with simulation results to evaluate the performance of the active filters for compensating power quality problems under transient- and steady-state conditions. Next, we discuss the integration of active filters with renewable energy sources (RENs) including a brief explanation of maximum power point tracking (MPPT) algorithms and other controllers considering a decentralized microgrid scenario with several active filters connected at the same grid circuit
