Modeling complex wells with the multi-scale finite-volume method

In this paper, an extension of the multi-scale finite-volume (MSFV) method is devised, which allows to Simulate flow and transport in reservoirs with complex well configurations. The new framework fits nicely into the data Structure of the original MSFV method,and has the important property that large patches covering the whole well are not required. For each well. an additional degree of freedom is introduced. While the treatment of pressure-constraint wells is trivial (the well-bore reference pressure is explicitly specified), additional equations have to be solved to obtain the unknown well-bore pressure of rate-constraint wells. Numerical Simulations of test cases with multiple complex wells demonstrate the ability of the new algorithm to capture the interference between the various wells and the reservoir accurately.

Caracterización ambiental y potencial pesquero 2004-2011: Bahía de Samanco, Chimbote, Perú.

El desarrollo de la maricultura en la Bahía de Samanco ha ocasionado descarga de restos orgánicos al ecosistema marino; se efectuaron monitoreos en esta Bahía en época de veda y de actividad pesquera industrial del 2005 al 2010; temperatura, salinidad y nutrientes se mantuvieron normales, pudiéndose afirmar que la capacidad de resiliencia del ecosistema no está afectada. Los parámetros fisicoquímicos, aceites y grasa presentaron altas concentraciones del 2007 al 2010, en relación al valor límite de los Estándares de Calidad Ambiental. La pesca artesanal generó 21.416 t de recursos hidrobiológicos, conformado por moluscos 57,78%, peces óseos 38,68%, equinodermos 3,20% y crustáceos, celentéreos y algas. La diversidad correspondió a 114 especies, mayor relevancia íctica dada por pejerrey, lisa, machete, lorna y coco; los invertebrados fueron concha de abanico, navajuela, calamar, marucha, caracol y ancoco. La captura de la pesca industrial de madera y artesanal anchovetera para consumo fue de 7.039 t, se identificaron 15 especies: peces (13) e invertebrados (2), la anchoveta aportó 98,71%. Se registraron 11 especies de fitoplancton potencialmente tóxicos, diatomeas: Pseudonitzschia cf delicatissima y P. pungens; dinoflagelados: Alexandrium sp., Dinophysis acuminata, D. caudata, D. rotundata, D. tripos, Gymnodinium sp., Prorocentrum mínimum, Protoperidinium crassipes y P. depressum.

Measuring researchers' use of scholarly information through social bookmarking data: a case study of BibSonomy

This paper explores the possibility of using data from social bookmarking services to measure the use of information by academic researchers. Social bookmarking data can be used to augment participative methods (e.g. interviews and surveys) and other, non-participative methods (e.g. citation analysis and transaction logs) to measure the use of scholarly information. We use BibSonomy, a free resource-sharing system, as a case study. Results show that published journal articles are by far the most popular type of source bookmarked, followed by conference proceedings and books. Commercial journal publisher platforms are the most popular type of information resource bookmarked, followed by websites, records in databases and digital repositories. Usage of open access information resources is low in comparison with toll access journals. In the case of open access repositories, there is a marked preference for the use of subject-based repositories over institutional repositories. The results are consistent with those observed in related studies based on surveys and citation analysis, confirming the possible use of bookmarking data in studies of information behaviour in academic settings. The main advantages of using social bookmarking data are that is an unobtrusive approach, it captures the reading habits of researchers who are not necessarily authors, and data are readily available. The main limitation is that a significant amount of human resources is required in cleaning and standardizing the data.

BCOR analysis in patients with OFCD and Lenz microphthalmia syndromes, mental retardation with ocular anomalies, and cardiac laterality defects.

Oculofaciocardiodental (OFCD) and Lenz microphthalmia syndromes form part of a spectrum of X-linked microphthalmia disorders characterized by ocular, dental, cardiac and skeletal anomalies and mental retardation. The two syndromes are allelic, caused by mutations in the BCL-6 corepressor gene (BCOR). To extend the series of phenotypes associated with pathogenic mutations in BCOR, we sequenced the BCOR gene in patients with (1) OFCD syndrome, (2) putative X-linked ('Lenz') microphthalmia syndrome, (3) isolated ocular defects and (4) laterality phenotypes. We present a new cohort of females with OFCD syndrome and null mutations in BCOR, supporting the hypothesis that BCOR is the sole molecular cause of this syndrome. We identify for the first time mosaic BCOR mutations in two females with OFCD syndrome and one apparently asymptomatic female. We present a female diagnosed with isolated ocular defects and identify minor features of OFCD syndrome, suggesting that OFCD syndrome may be mild and underdiagnosed. We have sequenced a cohort of males diagnosed with putative X-linked microphthalmia and found a mutation, p.P85L, in a single case, suggesting that BCOR mutations are not a major cause of X-linked microphthalmia in males. The absence of BCOR mutations in a panel of patients with non-specific laterality defects suggests that mutations in BCOR are not a major cause of isolated heart and laterality defects. Phenotypic analysis of OFCD and Lenz microphthalmia syndromes shows that in addition to the standard diagnostic criteria of congenital cataract, microphthalmia and radiculomegaly, patients should be examined for skeletal defects, particularly radioulnar synostosis, and cardiac/laterality defects.

New observations on Permian stratigraphy in Greece and geodynamic implication

New detailed stratigraphic and micropaleontological works on the famous exposures of Permian rocks in Hydra rich in Foraminifera, allows to define the stratigraphy of other outcrops in Aegina, Salamis, Attica and Chios. A synthetic section is presented which is characterized by the development of 3 successive carbonate platforms during the Permian and by 4 main tectonostratigraphic events. The youngest of these events marks the closure of the Paleotethyan ocean and the collision of a former Gondwanian/Cimmerian passive margin in the S with an active margin in the N.

Wages and prices in early Catalan industrialisation

[eng] Catalonia was the only Mediterranean region among the early followers of the British Industrial Revolution in the second third of the nineteenth century. The roots of this industrialisation process can be traced back to the seventeenth and eighteenth centuries when the Catalan economy became successfully integrated in international trade and the region enjoyed an intensification of its agrarian and proto-industrial activities. These capitalist developments were subsequently reinforced by a successful printed calico manufacturing business concentrated in the city of Barcelona. Although the factory system was largely adopted by the cotton industry in the 1840s, the diffusion of the spinning jenny had occurred earlier in the 1790s. In this paper, in line with Allen (2009a, 2009b), we explore whether relative factor prices played a role in the widespread adoption of the spinning jenny in Catalonia.
