Sangue e carne no cinema de Joaquim Pedro de Andrade

'Macunaíma' (Joaquim Pedro de Andrade, 1969) ends with a shot of blood emerging from the water. This text proposes an approach to this image following a comparison with other films by the same filmmaker: 'Couro de gato' (1960) and 'Os Inconfidentes' (1972). The main thesis is that in these images the aesthetical work with flesh synthesizes the ritual cannibalism and the capitalist one. This synthesis is specified in heroes’ assimilation by power.

Coupling liquid MALDI MS to liquid chromatography

Matrix-assisted laser desorption/ionisation (MALDI) coupled with time-of-flight (TOF) mass spectrometry (MS) is a powerful tool for the analysis of biological samples, and nanoflow high-performance liquid chromatography (nanoHPLC) is a useful separation technique for the analysis of complex proteomics samples. The off-line combination of MALDI and nanoHPLC has been extensively investigated and straightforward techniques have been developed, focussing particularly on automated MALDI sample preparation that yields sensitive and reproducible spectra. Normally conventional solid MALDI matrices such as α-cyano-4-hydroxycinnamic acid (CHCA) are used for sample preparation. However, they have limited usefulness in quantitative measurements and automated data acquisition because of the formation of heterogeneous crystals, resulting in highly variable ion yields and desorption/ ionization characteristics. Glycerol-based liquid support matrices (LSM) have been proposed as an alternative to the traditional solid matrices as they provide increased shot-to-shot reproducibility, leading to prolonged and stable ion signals and therefore better results. This chapter focuses on the integration of the liquid LSM MALDI matrices into the LC-MALDI MS/MS approach in identifying complex and large proteomes. The interface between LC and MALDI consists of a robotic spotter, which fractionates the eluent from the LC column into nanoliter volumes, and co-spots simultaneously the liquid matrix with the eluent fractions onto a MALDI target plate via sheath flow. The efficiency of this method is demonstrated through the analysis of trypsin digests of both bovine serum albumin (BSA) and Lactobacillus plantarum WCFS1 proteins.

O touro fica: anotações sobre 'O Testamento de Dom Quixote'

'O Testamento de Dom Quixote', 'script' by Glauber Rocha, is supposed to be loosely inspired in the last chapter of Cervantes' novel, although it is absolutely different from it: in the film the character doesn't recover his lucidity, but he lives surrounded by mystical delirium. Already in its first pages, it is obvious that it is a first draft of 'Cutting Heads', the film he shot in Spain in 1970, in spite of being completely different from the final movie. The comparison between both works allows us to see to what extent this essential seed was a forgotten one: the film was always publicised as a version of 'Macbeth', a reference which is missing here, and the 'Quijote' was never considered a point of depart, although its work with reality and dream determined the tone of the film from the very beginning.

Detecting defects in the UK new-build housing sector: a learning perspective

Rapid growth in the production of new homes in the UK is putting build quality under pressure as evidenced by an increase in the number of defects. Housing associations (HAs) contribute approximately 20% of the UK’s new housing supply. HAs are currently experiencing central government funding cuts and rental revenue reductions. As part of HAs’ quest to ramp up supply despite tight budget conditions, they are reviewing how they learn from defects. Learning from defects is argued as a means of reducing the persistent defect problem within the UK housebuilding industry, yet how HAs learn from defects is under-researched. The aim of this research is to better understand how HAs, in practice, learn from past defects to reduce the prevalence of defects in future new homes. The theoretical lens for this research is organizational learning. The results drawn from 12 HA case studies indicate that effective organizational learning has the potential to reduce defects within the housing sector. The results further identify that HAs are restricting their learning to focus primarily on reducing defects through product and system adaptations. Focusing on product and system adaptations alone suppresses HAs’ abilities to reduce defects in the future.
