Arte e etnografia cokwe: antes e depois de Marie-Louise Bastin

Este texto parte do recenseamento e debate sobre o contexto em que o trabalho empírico de Marie-Louise Bastin no Dundo (1956) e a publicação original de Art Décoratif Tshokwe (1961) ocorrem, e analisa as recorrências contemporâneas do contexto de produção de categorias de “arte africana” e o seu consumo como “arte nacional”. O trabalho levado a cabo no Museu do Dundo desde 1936 permite inscrever a emergência da categoria de arte durante os anos 50 e 60 no contexto da promoção internacional da cultura material cokwe como “arte”, em detrimento da sua classificação, até aí vigente, como “etnografia”. Neste sentido, a promoção dos artefactos cokwe como “arte” está em relação com uma nova política de desenvolvimento do museu – que, entre outros fatores, motivara a cessação de funções de José Redinha como conservador (em 1959) – no quadro das transformações políticas na arena internacional. A análise deste processo, argumenta-se, revela-se útil a dois níveis: por um lado, para pensar relações entre o local e o global mediadas pela categoria de “arte”; por outro, na medida em que a categoria de “arte” constitui um fator de empoderamento de sujeitos ou populações, a análise de processos passados pode tornar-se um ponto de partida para compreender processos contemporâneos, tais como os que são analisados e debatidos a propósito da 1.ª Trienal de Luanda, como se propõe na segunda parte deste texto.Departing from Marie-Louise Bastin’s research visit to the Dundo Museum in 1956 and the publication of both volumes of Cokwe Decorative Arts (1961), I analyze contemporary recurrences of the context of production of categories of “African art” and its consumption in Angola as “national art”. The colonial context in which Cokwe material culture, classified as ethnography, become classified as art, enabled a transition which developed in relationship to a new policy of development of the Dundo Museum. The analysis of this process is critical to understand local and global relationships mediated by the category of African art and its colonial efficacy, as well as it is illuminating of present-day politics, expressed in art terms, in contemporary Angola

Transparent cross-system consistency

This paper discusses the motivation and the challenges for providing a systematic and transparent approach for dealing with cross-system consistency. Our high level goal is to provide a way to avoid violations of causality when multiple systems interact, while (a) avoiding the redesign of existing systems, (b) minimizing the overhead, and (c) requiring as little developer input as possible.We sincerely thank the anonymous reviewers for their insightful comments and suggestions.

Partitioning of fibrinolytic protease from Bacillus sp. UFPEDA 485 by aqueous two-phase systems using PEG/sodium sulfate

XI Reunião Regional Nordeste da SBBq | 4th International Symposium in Biochemistry of Macromolecules and BiotechnologyThe fibrinolytic protease produced by bacteria of the genus Bacillus has attracted large interest in the pharmaceutical industry as a promising alternative in thrombolytic therapy due to their effectiveness in degrading fibrin, its production requiring the development of an efficient recovery process. Aqueous two-phase system (ATPS) have been recognized as an efficient and economical process for recovering enzymes due to their relative ease and low cost. The purpose of this work was to study the partition of fibrinolytic protease produced by Bacillus sp. UFPEDA 485 in a ATPS composed by Polyethylene glycol (PEG) and sodium sulfate using factorial design. The fibrinolytic protease production occurred in liquid culture medium containing 2% soy flour, pH 7.2, 150 rpm at 37 °C for 48 hours. To study the partitioning, was used a 23 full factorial design with four replicates at the central with the purpose of evaluating the effects and interactions of the independent variables: PEG molar mass (MMPEG), PEG concentration (CPEG) and sodium sulfate concentration (CNa2SO4) on the response variable: partition coefficient (K) of the fibrinolytic enzyme. In all the runs the enzyme partitioned to the top phase, indicating a significant interaction between the protein and the PEG. The best result was obtained at the central point, using MMPEG 6000 g/mol, CPEG 24 % and CNa2SO4 11,6 %. The partitions coefficients ranged between K = 327.63 and 2879.38. According to the results, the ATPS composed of PEG/sodium sulfate proved to be a promising method to extraction fibrinolytic protease.CAPES e CNPqinfo:eu-repo/semantics/publishedVersio

Mitochondrial DNA studies of Lisbon immigrants from Portuguese speaking African countries

Since the end of the 1970s, Portugal has had an important role in migratory movements, becoming a destination for immigrants of a wide range of nationalities, mainly from African countries. According to PORDATA, until the end of 2014 there were 40,000 immigrants from Cape Verde, 20,000 from Angola, 18,000 from Guinea-Bissau, and 3,000 from Mozambique living in Portugal, and of those, >80 per cent live in the Lisbon region. This may be one of the main contributors to genetic variation of Lisbon residents in the present and the future. Mitochondrial DNA (mtDNA) has features that make it desirable for forensics, namely, high copy number, lack of recombination, and matrilineal inheritance. These features are also important in evolutionary and population studies. We aim to characterize mtDNA diversity in immigrants from Portuguese Speaking African Countries (PALOP) living in Lisbon and their potential contribution to genetic variation of Lisbon population. Blood samples were collected from 439 PALOP immigrants living in Lisbon, of which 173 immigrants from Angola, 103 immigrants from Cape Verde, eighty-three immigrants from Mozambique and eighty immigrants from Guinea-Bissau, from January 2000 to December 2016. The control region of the mtDNA was amplified using two pairs of primers—L15971/H016 and L16555/H639, and sequenced by BigDye Terminator v.3.1 Cycle Sequence (AB). Sequenced products were detected in a sequencer Genetic Analyzer 3130 (AB). Finally the results were analysed by Sequencing Analysis v.5.2 software and also compared with Revised Cambridge Reference Sequence (rCRS) using SeqScape v.3 (AB) software. The haplogroups were determined based on Phylotree, build 17. Genetic distances and other genetic parameters were calculated with Arlequin software ver.3.5 and analysed and represented with PhyML 3.0. For each sample, the complete sequence of the control region was obtained. The comparison of the sequences obtained with the rCRS, among the 439 analysed individuals, allowed the identification of 319 different haplotypes, corresponding to 164 different haplogroups distributed by ten macrohaplogroups. Macrohaplogroup L was the most common with 386 haplotypes followed by U with fifteen haplotypes, H with twelve haplotypes, M and T with six haplotypes, K with five, R with four, X and J with two and HV with one. PALOP’s immigrants presented a high number of unique haplotypes, most of them belonging to macrohaplogroup L, originating from sub-Saharan regions of Africa.This macrohaplogroup is uncommon in European and Portuguese populations. Consistent with this, phylogenetic analysis showed the establishment of two distinct groups, one composed of the Portuguese population and another of the African populations. In comparing the different immigrant populations living in Lisbon, the genetically closest community to the Portuguese population is Mozambique and the furthest is Cape Verde, followed by Guinea-Bissau and Angola. Our results show that the PALOP immigrants living in Lisbon are genetically heterogeneous. The increase in genetic diversity in Lisbon due to immigrants from PALOP countries may have a major impact on haplotypic and allelic frequencies, on which all forensic and medico-legal investigations are based

Geo-Replication: Fast If Possible, Consistent If Necessary *

Abstract Ge

Geo-Replication: Fast If Possible, Consistent If Necessary

International audienceGeo-replicated storage systems are at the core of current Internet services. Unfortunately, there exists a fundamental tension between consistency and performance for offering scalable geo-replication. Weakening consistency semantics leads to less coordination and consequently a good user experience, but it may introduce anomalies such as state divergence and invariant violation. In contrast, maintaining stronger consistency precludes anomalies but requires more coordination. This paper discusses two main contributions to address this tension. First, RedBlue Consistency enables blue operations to be fast (and weakly consistent) while the remaining red operations are strongly consistent (and slow). We identify sufficient conditions for determining when operations can be blue or must be red. Second, Explicit Consistency further increases the space of operations that can be fast by restricting the concurrent execution of only the operations that can break application-defined invariants. We further show how to allow operations to complete locally in the common case, by relying on a reservation system that moves coordination off the critical path of operation execution

Oceanographic processes and products around the Iberian margin: a new multidisciplinary approach

Our understanding of the role of bottom currents and associated oceanographic processes (e.g., overflows, barotropic tidal currents) including intermittent processes (e.g., vertical eddies, deep sea storms, horizontal vortices, internal waves and tsunamis) is rapidly evolving. Many deep-water processes remain poorly understood due to limited direct observations, but may generate significant depositional and erosional features on both short- and long-term time scales. This paper describes these oceanographic processes and examines their potential role in the sedimentary features around the Iberian margin. The paper explores the implications of the processes studied, given their secondary role relative to other factors such as mass-transport and turbiditic processes. An integrated interpretation of these oceanographic processes requires an understanding of contourites, sea-floor features, their spatial and temporal evolution, and the near-bottom flows that form them. Given their complex, three-dimensional and temporally-variable nature, integration of these processes into sedimentary, oceanographic and climatological frameworks will require a multidisciplinary approach that includes Geology, Physical Oceanography, Paleoceanography and Benthic Biology. This approach will synthesize oceanographic data, seafloor morphology, sediments and seismic images to improve our knowledge of permanent and intermittent processes around Iberia, and evaluate their conceptual and regional role in the sedimentary evolution of the margin.Department of Earth Sciences, University of Gothenburg.
