Carbon capture and storage is a technology that can contribute to face the challenge of rising energy demand combined with a growing environmental awareness. In the present work, the CO2 capture process with monoethanolamine (MEA) is modeled using the simulation tool Aspen Plus. Two different modeling approaches are studied and compared: the equilibrium and the rate-based approaches. An optimization of key process parameters is performed and process modifications are studied with the objective of improving the global process energy efficiency. [less ▲]

This paper presents a multi-scale framework for the failure of periodic quasi-brittle thin planar shells. The failure behavior of textured or periodic heterogeneous materials is strongly influenced by their mesostructure. Their periodicity and the quasi-brittle nature of their constituents result in complex behaviors such as damage-induced anisotropy properties with localization of damage, which are difficult to model by means of macroscopic closed-form constitutive laws. A computational homogenization procedure is used for the in-plane and out-of-plane behavior of such planar shells, and is combined with an acoustic tensor-based failure detection adapted to shell kinematics to detect the structural-scale failure. Based on an assumption of single period failure, the localization of damage at the structural scale is represented by means of mesostructurally informed embedded strong discontinuities incorporated in the macroscopic shell description. A new enhanced scale transition is outlined for shell failure, based on an approximate energy consistency argument to objectively upscale the energy dissipation. The corresponding multi-scale framework results are compared with direct fine-scale modeling results used as a reference for the case of masonry, showing good agreement in terms of the load-bearing capacity, of failure mechanisms and of associated energy dissipation. © 2010 John Wiley & Sons, Ltd.

OBJECTIVE: Telomeres are protected by tightly regulated factors and elongated by telomerase. Short and/or deprotected chromosomes are recombinogenic and thereby cancer prone. MATERIALS AND METHODS: Together with the quantification of telomerase activity (TA), measuring telomere length (TL) and expression of the genes that govern telomere protection and elongation are useful for assessing telomere homeostasis. RESULTS: By these means we demonstrate that TL, hTERT, and TA are in the order acute myelogenous leukemia (AML) > T-cell acute lymphoblastic leukemia (T-ALL) > B-cell acute lymphoblastic leukemia (B-ALL) > T-ALL > AML, and B-ALL > AML > T-ALL. AML0 and AML3 display the lowest amounts of hTERT transcripts, and ALL and AML cells with cytogenetic abnormalities possess the shortest telomeres. hTERT expression includes phenotype-specific RNA maturation and correlates with TA but not with TL. A wide ratio of TA to hTERT expression between leukemia subtypes suggests phenotype-specific hTERT post-transcriptional deregulations. B- and T-ALL overexpress Ku70 and Pinx1, T-ALL PTOP and RAP1, and B-ALL TRF2, the expression of which is significantly higher in cases with abnormal karyotype. hTERT transcription and TL correlate with response to intensive chemotherapy, and hTERT and RAD50 are independent prognostic factors for survival. CONCLUSIONS: Each leukemia subtype possesses specific telomere dysregulations that rely on phenotype, karyotype, response to treatment, and survival. [less ▲]

The impact of pollution on the environment is causing several problems that are to be reduced as much as possible. One important example is the production of CO2 that is emitted by many transport and industrial applications. An interesting solution is to view CO2 as a source instead of a product that can be stocked. The case considered in this work is the CO2 reformation of methane producing hydrogen and CO. It is an endothermic reaction, for which the activition barrier needs to be overcome. The method of Dielectric Barrier Discharge can do this efficiently. The process relies on the collision of electrons, which are accelerated under an electrical field that is created in the discharge area. This leads to the formation of reactive species, which facilitate the abovementioned reaction. The determination of the electron density is performed by PLASIMO. The study is subsequently continued using the Reaction Engineering module in COMSOL (with an incorporated kinetic mechanism) in order to model the discharge phase. Then COMSOL (continuity and Navier-Stokes equations) is used to model the flow in the post-discharge phase. The results showed that both a 2D and 3D model can be used to model the chemical-plasma process. These methods need strongly reduced kinetic mechanism, which in some cases can cause loss of precision. It is also observed that the present experimental set-up that is modeled needs to be improved. A suggestion is made. [less ▲]

En Afrique Subsaharienne, les taux d’adhésion aux mutuelles de santé restent généralement à des niveaux très faibles. Cet article vise à synthétiser les résultats des enquêtes déjà réalisées pour identifier les facteurs qui influencent la décision d’adhérer ou non à ces mutuelles. Au-delà des différences méthodologiques entre ces travaux, notre synthèse fait ressortir deux facteurs majeurs qui étaient plutôt attendus (la capacité financière des populations et la qualité des soins) et les resitue dans une perspective plus large. Elle permet également d’identifier quelques autres paramètres qui semblent aussi jouer un rôle significatif même si les convergences entre les enquêtes sont moins nettes. [less ▲]

The fist lynx were seen in eastern Belgium at the end of the 1990s. Since then, both sightings and tracks have been recorded there and in the Ardenne (south east Belgium). Whether this presence indicates a spontaneous return of individuals deriving from the population reintroduced in Germany or results from illicit releases, it raises the question of the suitability and the carrying capacity of habitats in an area of dense human occupation. Using two software programs, a mapping model to assess habitat characterization, drawn from relevant criteria for this species, was tested to estimate the potential host of the study area, via the determination of areas of suitable habitats, and the dispersion potential of the species, through the identification of the most viable dispersal corridors. The findings of the study (multi criteria analysis of potential host of habitats, identification of corridors of lowest cost, estimation of the potential population...), compiled on the basis mapping model and simulations, suggest that a return of the lynx in Wallonia may be sustainable if supported and managed wisly by the regional administrative services.

Las distintas contribuciones constituyen sendas revisiones de las actitudes y resonancias que la rebelión del EZLN ha suscitado entre científicos, intelectuales y escritores, en México, pero también en otras partes del mundo, desde sus orígenes en 1994 hasta 2006. En la primera parte las contribuciones exploran las resonancias en el ámbito de las ciencias sociales y naturales, luego se pasa a revisar posiciones de intelectuales y finalmente se examina cómo la rebelión zapatista se ha convertido en un tema literario que inspiró a dos escritores españoles y a tres importantes escritores mexicanos. En calidad de cofundador de la Unión de Científicos Comprometidos con la Sociedad (UCCS), Iván Azuara Monter analiza cómo el fenómeno zapatista incidió y resonó sobre todo entre los practicantes de las llamadas ciencias duras y la investigación regional, un tema que ha sido muy poco trabajado hasta hoy. En cambio, Óscar García Agustín y Bernard Duterme se centran en las interpretaciones de la rebelión zapatista que hicieron científicos sociales y políticos de diferentes tendencias y pertenecientes a distintas escuelas. García Agustín toma como hilo conductor las manifestaciones en torno a la conceptualización por parte de algunos académicos de izquierda que se pronunciaron sobre el EZLN, entre ellos John Holloway, Raúl Zibechi, Antonio Negri y Atilio Boron. Duterme también se propone entender lo que distingue y acerca las diversas aproximaciones sociológicas al EZLN pero percibe sobre todo divergencias entre el enfoque marxista por un lado y la perspectiva representada por el sociólogo Alain Touraine por el otro. Por su parte, Anne Huffschmid y Juan Pellicer estudian la interacción entre el nuevo zapatismo y determinados intelectuales quienes, en el sentido de mediadores culturales o comentaristas políticos, han publicado sus opiniones en torno al EZLN. Huffschmid, después de recapitular algunos factores que integran una particular semiótica de la resistencia y que han resonado en distintas escenas de recepción, recrea algunas de las posturas centrales de intelectuales simpatizantes, y también adversarios, en relación con el nuevo zapatismo. Asimismo se ocupa del actual desencantamiento del EZLN con buena parte de la opinión pública, y que explica por quiebres comunicativos y por un giro sectario del grupo armado que parece traicionar a su propio imaginario político. El texto de Juan Pellicer se concentra en las respuestas dadas por Octavio Paz, en cuyo discurso descubre una evolución notable en cuanto a la visión del indígena al que presenta como piedra de toque de la nación en El laberinto de la soledad y al que percibe como un estorbo a la modernización de México en los textos sobre el EZLN. La contribución de Kristine Vanden Berghe vuelve brevemente sobre la postura de Octavio Paz pero lo hace en el marco de un análisis del ensayo de Manuel Vázquez Montalbán, Marcos : El señor de los espejos. El discurso del escritor catalán, por su parte, es abordado en función de su relación intertextual con la novela Turistas del ideal de Ignacio Vidal-Folch, una sátira de los intelectuales que apoyan al EZLN. La imagen tradicional del intelectual paratópico que se identifica con cuantos escapen de las líneas de demarcación dentro de la sociedad, como es el caso de los indígenas, es desplazada en esta sátira a favor de un intelectual hipócrita e inconsciente de sus propias contradicciones. Entre los –relativamente pocos- poetas y escritores que se han referido al EZLN en su creación literaria, también encontramos a tres autores importantes de Chiapas que, directamente interpelados por el movimiento armado, escribieron sobre él. Jan De Vos estudia estos textos que son, respectivamente, de la pluma del cuentista Eraclio Zepeda y de los poetas Juan Bañuelos y Efraín Bartolomé. En la reflexión que nos propone, De Vos suscita la emoción que la lectura del trío chiapaneco le produce y la combina con la mirada crítica que le impone su disciplina de científico social. Procura interrogar a estos autores que admira sobre los motivos y la manera en que se dejaron interpelar por el movimiento rebelde que en 1994 estalló en las montañas y selvas de su tierra natal.
