The magical transformation contest in the ancient storytelling tradition

El concurso de transformación mágica, esquema narrativo difundido en la tradición popular, se presenta en dos variantes principales: los hechiceros que compiten pueden metamorfosearse en varios seres o crear esos seres por medios mágicos. En cualquier caso el concursante ganador da a luz criaturas más fuertes que superan las de su oponente. La segunda variante fue preferida en el antiguo Cercano Oriente (Sumeria, Egipto, Israel). La primera se puede encontrar en algunos mitos griegos sobre cambiadores de forma (por ejemplo, Zeus y Némesis). El mismo esquema narrativo puede haber influido en un episodio de la Novela de Alejandro (1.36-38), en el que Darío envía regalos simbólicos a Alejandro y los dos monarcas enemigos ofrecen contrastantes explicaciones de ellos. Esta historia griega racionaliza el concurso de cuento de hadas, transfiriendo las fantásticas hazañas de creaciones milagrosas a un plano secundario pero realista de metáfora lingüística.

Putting the magic in magic bullets: top three global priorities for sexually transmitted infection control

Setting practical priorities for sexually transmitted infection (STI) control is a balance between idealism and pragmatism. Infections transmitted through unsafe sex (chlamydia, gonorrhoea, syphilis, HIV, hepatitis B and human papillomavirus (HPV) infections) rank in the top five causes of the global burden of disease.1 Their distribution in populations is driven by a complex mixture of individual behaviours, social and community norms and societal and historical context. Ideally, we would be able to reduce exposure to unsafe sex to its theoretical minimum level of zero and thus eliminate a significant proportion of the current global burden of disease, particularly in resource-poor settings.2 Ideally, we would have ‘magic bullets’ for diagnosing and preventing STI in addition to specific antimicrobial agents for specific infections.3 Arguably, we have ‘bullets’ that work at the individual level; highly accurate diagnostic tests and highly efficacious vaccines, antimicrobial agents and preventive interventions.4 Introducing them into populations to achieve similarly high levels of effectiveness has been more challenging.4 In practice, the ‘magic’ in the magic bullet can be seen as overcoming the barriers to sustainable implementation in partnerships, larger sexual networks and populations (figure 1).4 We have chosen three (pragmatic) priorities for interventions that we believe could be implemented and scaled up to control STI other than HIV/AIDS. We present these starting with the partnership and moving up to the population level.

Electrical energy balance contest in Solar Decathlon Europe 2012

Solar Decathlon Europe (SDE) is an international multidisciplinary competition in which 20 universityteams build and operate energy-efficient solar-powered houses. The aim of SDE is not only scientificbut also educational and divulgative, making visitors to understand the problems presented by realengineering applications and architecture. From a research perspective, the energy data gathered dur-ing the competition constitutes a very promising information for the analysis and understanding of thephotovoltaic systems, grid structures, energy balances and energy efficiency of the set of houses. Thisarticle focuses on the electrical energy components of SDE competition, the energy performance of thehouses and the strategies and behaviors followed by the teams. The rules evaluate the houses? electricalenergy self-sufficiency by looking at the electricity autonomy in terms of aggregated electrical energybalance; the temporary generation-consumption profile pattern correlation; and the use of electricityper measurable area. Although the houses are evaluated under the same climatological and consump-tion conditions, production results are very different due to the specific engineering solutions (differentelectrical topologies, presence or absence of batteries, diverse photovoltaic module solutions, etc.)

Investigation of ultrasonic properties of PAG and MAGIC polymer gel dosimeters

Ultrasonic speed of propagation and attenuation were investigated as a function of absorbed radiation dose in PAG and MAGIC polymer gel dosimeters. Both PAG and MAGIC gel dosimeters displayed a dependence of ultrasonic parameters on absorbed dose with attenuation displaying significant changes in the dose range investigated. The ultrasonic attenuation dose sensitivity at 4 MHz in MAGIC gels was determined to be 4.7 +/- 0.3 dB m(-1) Gy(-1) and for PAG 3.9 +/- 0.3 dB m(-1) Gy(-1). Ultrasonic speed dose sensitivities were 0.178 +/- 0.006 m s(-1) Gy(-1) for MAGIC gel and -0.44 +/- 0.02 m s(-1) Gy(-1) for PAG. Density and compressional elastic modulus were investigated to explain the different sensitivities of ultrasonic speed to radiation for PAG and MAGIC gels. The different sensitivities were found to be due to differences in the compressional elastic modulus as a function of dose for the two formulations. To understand the physical phenomena underlying the increase in ultrasonic attenuation with dose, the viscoelastic properties of the gels were studied. Results suggest that at ultrasonic frequencies, attenuation in polymer gel dosimeters is primarily due to volume viscosity. It is concluded that ultrasonic attenuation significantly increases with absorbed dose. Also, the ultrasonic speed in polymer gel dosimeters is affected by changes in dosimeter elastic modulus that are likely to be a result of polymerization. It is suggested that ultrasound is a sufficiently sensitive technique for polymer gel dosimetry.

The most Portuguese village in Portugal: tradition in the age of its technical reproducibility

Ethnographic film is often associated with many European countries’ past as colonial powers and the way these countries used film to depict African, American and Asian territories and populations they once ruled. However, ethnographic film also has a European tradition of its own, closely interlaced with the history of ethnography and anthropology as autonomous sciences and with the desire of scholars to represent local, regional and national cultural identities. This paper presents a Portuguese attempt of this sort dating from 1938, when the authoritarian regime organized a national contest to determine which would be Portugal’s most “authentic” village – something other European countries also did. As part of this metonymic contribution to the construction of Portugal’s national identity as an agrarian utopia, a short documentary was shot, sponsored by the same official propaganda office that had organized the contest. In this film, the viewer’s gaze is made to coincide with the one of the national jury visiting the final selection of 12 villages and to whose benefit local scholars had organized all sorts of colourful peasant traditions hoping to cause the strongest impression. The film makes a strong case for the importance of ethnographic film as a relevant instance not only of the iteration of existing European national cultures, but also of the construction of so many of Europe’s national identities and traditions. Suffice to say that even today the village of “Monsanto”, which won the 1938 contest, is still referred to as “Portugal’s most Portuguese village”.

Metabolic evaluation of Crioulo horses participating in competitions of 750 km

The Crioulo breed of horses performs in one of the most physically demanding equestrian competitions, the Marcha de Resistência, which is a contest in which the horses run 750 km in 15 days. The study's aim was to characterize the metabolic responses during this period. We evaluated eleven Crioulo horses in the competition, specifically, two males and nine females. Blood samples were collected 24 hours before the contest and on the 4th, 9th, 11th, 14th and 15th days of competition. We evaluated CK, AST, LDH, glucose, lactate, urea, creatinine, sodium, potassium, chloride, magnesium, total calcium, ionized calcium, total protein, hematocrit and the white blood cell count. At the end of the competition, the mean values of serum AST were 1151±358 IU/ L the mean LDH values were 7418±1695 IU/L and CK was 13,867±3998UI /L. There was a significant increase in urea, creatinine and lactate (p<0.0001). A decrease in the mean values of chloride, sodium, potassium, and total and ionized calcium was observed (p≤0.0002). An evaluation of the total leukocytes and segmented neutrophils (p≤0.0002) revealed their increased values, and decreased values were observed for hematocrit, plasma protein and total lymphocytes (p≤0.0003). The values of glucose, on average, remained constant. Based on these data, we conclude that the Marcha de Resistência competition necessitated a high muscular demand and the depletion of energy and electrolytes, suggesting an inflammatory process in the animals evaluated.

Experiences and methodology in a multidisciplinary energy and architecture competition: Solar Decathlon Europe 2012

Solar Decathlon Europe is an international competition among universities which promotes interdisciplinary learning in engineering and architecture. Students from different disciplines participate in teams guided by several professors during a 29 month preparation period plus five weeks of on-site contest. The educational project involves designing, building and testing a solar energy house connected to the electrical grid with the strategy of maximizing self-consumption, supported by bioclimatic technologies and maintaining a low environmental footprint. It culminates in a on-site contest in which teams must assembly the house themselves, test it with ordinary real life tasks and finally disassembly it. The event has also a divulgative aim, trying to make students and visitors get interested in discovering the problems presented by real engineering and architecture applications. In addition, SDE covers R&D aspects in different fields such as energy efficiency, solar energy and bioclimatic architecture. This article presents the methodology followed during the SDE 2012 edition, in which more than 850 students participated. The obtained results show that the educational competition was a success according to the technical and professional ambitions of the students, most of them considering that their knowledge had increased in areas related to technical and multidisciplinary aspects.

Biomarker analysis in oesophagogastric cancer: Results from the REAL3 and TransMAGIC trials.

BACKGROUND: REAL3 (Randomised ECF for Advanced or Locally advanced oesophagogastric cancer 3) was a phase II/III trial designed to evaluate the addition of panitumumab (P) to epirubicin, oxaliplatin and capecitabine (EOC) in untreated advanced oesophagogastric adenocarcinoma, or undifferentiated carcinoma. MAGIC (MRC Adjuvant Gastric Infusional Chemotherapy) was a phase III study which demonstrated that peri-operative epirubicin, cisplatin and infused 5-fluorouracil (ECF) improved survival in early oesophagogastric adenocarcinoma. PATIENTS AND METHODS: Analysis of response rate (RR; the primary end-point of phase II) and biomarkers in the first 200 patients randomised to EOC or modified dose (m) EOC+P in REAL3 was pre-planned to determine if molecular selection for the on-going study was indicated. KRAS, BRAF and PIK3CA mutations and PTEN expression were assessed in pre-treatment biopsies and results correlated with response to mEOC+P. Association between these biomarkers and overall survival (OS) was assessed in MAGIC patients to determine any prognostic effect. RESULTS: RR was 52% to mEOC+P, 48% to EOC. Results from 175 assessable biopsies: mutations in KRAS (5.7%), BRAF (0%), PIK3CA (2.5%) and loss of PTEN expression (15.0%). None of the biomarkers evaluated predicted resistance to mEOC+P. In MAGIC, mutations in KRAS, BRAF and PIK3CA and loss of PTEN (phosphatase and tensin homolog) were found in 6.3%, 1.0%, 5.0% and 10.9%, respectively, and were not associated with survival. CONCLUSIONS: The RR of 52% in REAL3 with mEOC+P met pre-defined criteria to continue accrual to phase III. The frequency of the mutations was too low to exclude any prognostic or predictive effect.

Territorialização do campesinato no sudeste do Pará

Investiga o processo de territorialização camponesa em regiões da Amazônia marcadas pela aguda disputa pela terra, recursos naturais. Trata-se do sul e sudeste paraense, regiões de fronteira imortalizadas pelo elevado índice de violência contra camponeses e seus apoiadores. Para tanto usamos referências da geografia, história, antropologia, sociologia e política. A pesquisa parte da hipótese que houve uma territorialização camponesa, produto da pressão, negociações e acomodações de forças sociais e políticas no sudeste do Pará, onde concorrem na disputa pelo território ações políticas e econômicas em escalas nacionais e internacionais. Investiga sob que contexto se desenvolve tal territorialização, quais agentes internos e externos estão presentes e que processos anteriores foram articulados pelas entidades camponesas. Identifica os antagonistas dos camponeses, bem como os pares que se associaram na caminhada em busca do reconhecimento político, social e econômico.

O uso do modelo físico e digital nos processos de projeto da arquitetura contemporânea

Durante o processo de projeto, o arquiteto transpõe suas ideias para o campo real, do concreto. Os diversos modos de expressão e representação têm como função mediar essa interação, diminuindo a distância entre esses dois campos. Vive-se hoje, um momento de intensa transformação das estratégias projetuais, propiciadas pelos novos meios digitais. Esta pesquisa tem como objetivo o estudo do uso das representações tridimensionais, especificamente dos modelos físicos e digitais. Pretende-se flagrar os momentos contributivos dos modelos no processo projetivo e as características intrínsecas a eles. A discussão busca não apenas destacar a importância dessa ferramenta, como também, traçar uma breve comparação entre a tecnologia digital e a feitura manual. Para este trabalho foram selecionados alguns arquitetos significativos do cenário da arquitetura paulista em cujos projetos comparecem o uso de modelos. Como estudos de caso tem-se a Residência do arquiteto Marcos Acayaba e o projeto vencedor do Concurso para o Instituto Moreira Salles/ SP, do escritório Andrade Morettin Arquitetos. Soma-se a estes objetivos, a apresentação do uso de modelos físicos e digitais em uma experiência didática projetiva.
