Alice's anima or the obligation of a reading transliteracy

This paper suggests an analysis of "Inanimate Alice" by Kate Pullinger, Chris Joseph and Ian Harper as an example of a transmedia narrative that triggers a new reading experience whilst proposing a literary alterity between reading and performance. Narrative experiences that elect the visual plasticity, interchanging games and tactility as drivers of the creative process are not new. Yet, narrative experiences, which have been created in the gap between reality and fiction, have found on the digital realm the perfect environment to multiple hybrid experiences. Bearing in mind Walter Benjamin’s concept of Erlebnis and Erfahrung, a critical analysis of this digital fiction tries to illustrate how literary art finds its space and time in a metamorphosed continuum only activated by the “patient reader”. All the multimedia hybrids, which this digital literary work may have, challenge readers to interpret different signals and poetic structures that most of readers might not be accustomed to; however even among a cognitive dissonance, meaning is found and reading happens only if time, space and attention are available. All possible transmedia literacies can only respond to this experience of online reading, if they are able to focus and draw attention not to a simple new behaviour or a single new practice, but to a demanding state of affairs that assemble different objective and subjective value forms.

Formaldeído em habitações domésticas: contaminação ambiental e potenciais fontes

Do ponto de vista das preocupações de saúde, os níveis de contaminação do ar interior assumem actualmente uma elevada importância quando se tem em consideração que as pessoas passam a maior parte do seu tempo no interior de edifícios. Neste contexto, o formaldeído é um dos poluentes mais preocupantes e, inclusivamente, os resultados de concentração obtidos em habitações do espaço Europeu foram considerados preocupantes devido ao facto de estarem relacionados com efeitos negativos para a saúde. O estudo exploratório desenvolvido pretendeu disponibilizar informação acerca das concentrações de formaldeído existentes em habitações domésticas portuguesas. Estudou‑se a presença de formaldeído em habitações novas e habitações domésticas com ocupação, abrangendo 6 unidades de cada um dos tipos considerados. Para a avaliação ambiental foi utilizado um equipamento de leitura direta que deteta as concentrações de formaldeído por fotoionização com uma lâmpada de 11,7 eV. A temperatura ambiente e a humidade relativa foram igualmente medidas, de acordo com o estipulado na Norma Internacional ISO 7726:1998. No caso das habitações novas foram registados valores de concentração superiores a 0,08 ppm em 3 das unidades estudadas. Por outro lado, em 4 das habitações com ocupação foram obtidos valores superiores a 0,08 ppm. O desenvolvimento deste estudo permitiu reconhecer algumas das possíveis fontes emissoras e os factores que influenciam as concentrações de formaldeído nas habitações em Portugal. ABSTRACT - Nowadays, indoor air contamination is considering an important health issue considering that people spend most of their time indoors. In this context, formaldehyde is a pollutant of major concern and, recently, concentration results obtained in European dwellings reveal high concentrations and values related with negative health effects in occupants. The present exploratory study sought to provide information about formaldehyde concentrations in Portuguese dwellings. It was studied formaldehyde presence in new dwellings and dwellings with occupation and included 6 units of each setting. For concentrations measure, it was used a direct‑reading equipment that detects formaldehyde concentration by photoionization. Temperature and relative humidity were also measured in accordance with International Standard ISO 7726:1998. In the case of new dwellings, in 3 units concentration values were higher than 0.08 ppm. In addition, in 4 units of the 6 dwellings with occupation, concentrations higher than this reference value were obtained. The development of this study permitted to recognize some of the possible indoors emissions sources and to define several of the preventive measures that can be applied.

Constructing good deals in discrete time arbitrage-free dynamic pricing models

Recent literature has proved that many classical pricing models (Black and Scholes, Heston, etc.) and risk measures (V aR, CV aR, etc.) may lead to “pathological meaningless situations”, since traders can build sequences of portfolios whose risk leveltends to −infinity and whose expected return tends to +infinity, i.e., (risk = −infinity, return = +infinity). Such a sequence of strategies may be called “good deal”. This paper focuses on the risk measures V aR and CV aR and analyzes this caveat in a discrete time complete pricing model. Under quite general conditions the explicit expression of a good deal is given, and its sensitivity with respect to some possible measurement errors is provided too. We point out that a critical property is the absence of short sales. In such a case we first construct a “shadow riskless asset” (SRA) without short sales and then the good deal is given by borrowing more and more money so as to invest in the SRA. It is also shown that the SRA is interested by itself, even if there are short selling restrictions.

A importância de um programa de atividade física em doentes com esclerose múltipla na satisfação com a vida e bem-estar psicológico

A Esclerose Múltipla (EM) é uma doença crónica do sistema nervoso central, que afeta com mais frequentemente mulheres jovens. A EM é uma doença progressiva e imprevisível, resultando em alguns casos de incapacidades e limitações a nível físico, psicológico e social. Este estudo tem como objetivo verificar o efeito de um programa de intervenção para a promoção da atividade física (PIPAF) em indivíduos com EM no bem-estar psicológico (BEP) e na satisfação com a vida (SV). Métodos – É um estudo quasi-experimental. Utilizamos a escala de satisfação com a vida (7 itens) e a componente BEP do inventário de saúde mental (14 itens). O estudo inclui 24 doentes EM com idade média de 44 anos, 58,3% são mulheres, 37,5% são casados, 67% estão reformados, a média de escolaridade é de 12,5 anos, sendo a EM diagnosticada há pelo menos um ano. O programa consiste numa intervenção para a promoção da atividade física em grupos de oito pessoas, semanalmente, durante 90 minutos, em sete semanas. Para analisar os resultados utilizamos o programa SPSS, versão 20. Resultados – Utilizamos o teste Wilcoxon para as variáveis BEP e a SV, obtido a partir da avaliação antes do programa de intervenção e no final do programa. Verificamos que houve alterações significativas entre os dois tempos p <0,01, em ambas as variáveis, com resultados mais elevados no final do programa de intervenção. Discussão/Conclusão – Através da leitura dos resultados podemos verificar que a implementação do PIPAF, em doentes com EM, utilizando um modelo holístico e integrado numa perspetiva biopsicossocial, melhora a SV e a BEP destes doentes.

Binocular vision and reading ability in a Portuguese population of school age children

Preventable visual loss caused by amblyopia (2 to 4%) and its risk factors such as strabismus (3%) and uncorrected refractive errors (5 to 7%) represent an important public health problem. Children with binocular vision anomalies could be at disadvantage in reading and writing. Objectives: (1) Describe binocular vision measures in children of school age; and (2) Describe the impact of abnormal binocular vision on reading ability (reading errors and reading speed).

Real-time rheology of actively growing bacteria

The population growth of a Staphylococcus aureus culture, an active colloidal system of spherical cells, was followed by rheological measurements, under steady-state and oscillatory shear flows. We observed a rich viscoelastic behavior as a consequence of the bacteria activity, namely, of their multiplication and density-dependent aggregation properties. In the early stages of growth (lag and exponential phases), the viscosity increases by about a factor of 20, presenting several drops and full recoveries. This allows us to evoke the existence of a percolation phenomenon. Remarkably, as the bacteria reach their late phase of development, in which the population stabilizes, the viscosity returns close to its initial value. Most probably, this is caused by a change in the bacteria physiological activity and in particular, by the decrease of their adhesion properties. The viscous and elastic moduli exhibit power-law behaviors compatible with the "soft glassy materials" model, whose exponents are dependent on the bacteria growth stage.

Optical processing devices based on a-SiCH multilayer architectures

Red, green and blue optical signals were directed to an a-SiC:H multilayered device, each one with a specific transmission rate. The combined optical signal was analyzed by reading out, under different applied voltages, the generated photocurrent. Results show that when a chromatic time dependent wavelength combination with different transmission rates irradiates the multilayered structure, the device operates as a tunable wavelength filter and can be used in wavelength division multiplexing systems for short range communications. An application to fluorescent proteins detection is presented. (C) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim

Disruption and phenotypic analysis of six open reading frames from chromosome VII of Saccharomyces cerevisiae reveals one essential gene

Six open reading frames (ORFs) located on chromosome VII of Saccharomyces cerevisiae (YGR205w, YGR210c, YGR211w, YGR241c, YGR243w and YGR244c) were disrupted in two different genetic backgrounds using short-flanking homology (SFH) gene replacement. Sporulation and tetrad analysis showed that YGR211w, recently identified as the yeast ZPR1 gene, is an essential gene. The other five genes are non-essential, and no phenotypes could be associated to their inactivation. Two of these genes have recently been further characterized: YGR241c (YAP1802) encodes a yeast adaptor protein and YGR244c (LSC2) encodes the b-subunit of the succinyl-CoA ligase. For each ORF, a replacement cassette with long flanking regions homologous to the target locus was cloned in pUG7, and the cognate wild-type gene was cloned in pRS416.

Analysis of a 17.9 kb region from Saccharomyces cerevisiae chromosome VII reveals the presence of eight open reading frames, including BRF1 (TFIIIB70) and GCN5 genes

We report the nucleotide sequence of a 17,893 bp DNA segment from the right arm of Saccharomyces cerevisiae chromosome VII. This fragment begins at 482 kb from the centromere. The sequence includes the BRF1 gene, encoding TFIIIB70, the 5' portion of the GCN5 gene, an open reading frame (ORF) previously identified as ORF MGA1, whose translation product shows similarity to heat-shock transcription factors and five new ORFs. Among these, YGR250 encodes a polypeptide that harbours a domain present in several polyA binding proteins. YGR245 is similar to a putative Schizosaccharomyces pombe gene, YGR248 shows significant similarity with three ORFs of S. cerevisiae situated on different chromosomes, while the remaining two ORFs, YGR247 and YGR251, do not show significant similarity to sequences present in databases.

Sequencing of a 9.9 kb segment on the right arm of yeast chromosome VII reveals four open reading frames, including PFK1, the gene coding for succinyl-CoA synthetase (beta-chain) and two ORFs sharing homology with ORFs of the yeast chromosome VIII

A 9.9 kb DNA fragment from the right arm of chromosome VII of Saccharomyces cerevisiae has been sequenced and analysed. The sequence contains four open reading frames (ORFs) longer than 100 amino acids. One gene, PFK1, has already been cloned and sequenced and the other one is the probable yeast gene coding for the beta-subunit of the succinyl-CoA synthetase. The two remaining ORFs share homology with the deduced amino acid sequence (and their physical arrangement is similar to that) of the YHR161c and YHR162w ORFs from chromosome VIII.

The complete sequence of a 9000 bp fragment of the right arm of Saccharomyces cerevisiae chromosome VII contains four previously unknown open reading frames

We report the sequence of a 9000 bp fragment from the right arm of Saccharomyces cerevisiae chromosome VII. Analysis of the sequence revealed four complete previously unknown open reading frames, which were named G7587, G7589, G7591 and G7594 following standard rules for provisional nomenclature. Outstanding features of some of these proteins were the homology of the putative protein coded by G7589 with proteins involved in transcription regulation and the transmembrane domains predicted in the putative protein coded by G7591.
