Software de gestión de equipamiento biomédico para pequeñas y medianas instituciones de la salud
Se ha detectado que las instituciones de la salud encuadradas en la actual resolución 267/2003 aprobada por el Ministerio de Salud de Argentina hasta el nivel 7, carecen de un sistema de gestión de equipamiento biomédico debido a la falta de oferta en el mercado y alto costo de desarrollo que, solo pueden afrontar grandes hospitales. Generando desconocimiento sobre el equipamiento existente y falta de mantenimiento preventivo y correctivo, creando riesgos y gastos evitables.
Por ello se ha desarrollado un software, denominado Maguss, para suplir esta necesidad, utilizando una plataforma web, con los objetivos de obtener bajo costo de implementación, utilizar el equipamiento existente, nula inversión, acceso remoto desde diversos dispositivos móviles y alto grado de seguridad, destinado a pequeñas y medianas instituciones.
La implementación en dos nosocomios de la ciudad de Córdoba dio excelentes resultados, permitiendo confirmar la necesidad de este tipo de sistemas y determinar las mejoras futuras que tendrán la colaboración del departamento de informática médica de la Facultad de Ciencias Exactas, Físicas y Naturales de la misma ciudad.Sociedad Argentina de Informática e Investigación Operativ

Holocene paleo-earthquakes recorded at the transfer zone of two majorfaults: the Pastores and Venta de Bravo fault (Trans-Mexican Volcanic Belt).
We present evidence of fi ve late Holocene earthquake ruptures observed at two paleoseismological trenches in the Laguna Bañí sag pond (Trans-Mexican Volcanic Belt, central Mexico). The trenches exposed two fault branches of the western termination of the Pastores fault, one of the major fault systems within the central Trans-Mexican Volcanic Belt. The site was studied by combining geomorphological and structural approaches, volcanic mapping, ground-penetrating radar, and paleoseismological analysis. The study revealed that coseismic surface rupture was noncharacteristic, and that the exposed fault branches had not always moved simultaneously. The fault tip has ruptured at least 5 times within the past 4 k.y., and the rupture events followed and preceded the deposition of an ignimbrite. The close temporal relationship of the seismic rupture with the volcanic activity of the area could be the result of volcanism triggered by faulting and its associated seismicity. The relatively high recurrence of seismic events (1.1 2.6 k.y.) and the noncharacteristic fault behavior observed at this tip of the Pastores fault suggest that the fault might have been active as a primary fault rupturing along segments of variable length or depth, and/or that the fault ruptured eventually as a secondary fault. The secondary ruptures would likely be related to earthquakes produced at major neighboring faults such as the Acambay fault, which moved during the 1912 Acambay earthquake, or the Venta de Bravo fault. A relatively large slip rate estimated for this fault branch (0.23 0.37 mm/yr) leads us to contemplate the possible connection at depth between the Pastores and the Venta de Bravo faults, increasing the maximum expected magnitude for central Mexico
Modelling ground rupture due to groundwater withdrawal: applications to test cases in China and Mexico
Abstract. The stress variation induced by aquifer overdraft in sedimentary basins with shallow bedrock may cause rupture in the form of pre-existing fault activation or earth fissure generation. The process is causing major detrimental effects on a many areas in China and Mexico. Ruptures yield discontinuity in both displacement and stress field that classic continuous finite element (FE) models cannot address. Interface finite elements (IE), typically used in contact mechanics, may be of great help and are implemented herein to simulate the fault geomechanical behaviour. Two main approaches, i.e. Penalty and Lagrangian, are developed to enforce the contact condition on the element interface. The incorporation of IE incorporation into a three-dimensional (3-D) FE geomechanical simulator shows that the Lagrangian approach is numerically more robust and stable than the Penalty, thus providing more reliable solutions. Furthermore, the use of a Newton-Raphson scheme to deal with the non-linear elasto-plastic fault behaviour allows for quadratic convergence. The FE – IE model is applied to investigate the likely ground rupture in realistic 3-D geologic settings. The case studies are representative of the City of Wuxi in the Jiangsu Province (China), and of the City of Queretaro, Mexico, where significant land subsidence has been accompanied by the generation of several earth fissures jeopardizing the stability and integrity of the overland structures and infrastructure.</p
Interwoven migration narratives: identity and social representations in the Lusophone world
First published online: 17 Oct 2016This article provides an exploratory analysis of the life narratives of migrants in the Portuguese-speaking world. By interweaving the life experiences of eight participants in three thematic clusters – ‘shared past’, language and sense of community – we propose a critique of the deep-seated idea of the Lusophone space as a community constructed by the harmonious conviviality of different countries and people. Drawing on contributions from cultural studies, social psychology, anthropology and sociology, we first aim to give voice to the human subjects who embark on migrations and then to understand how the engendered process of identity construction is framed by their social world, simultaneously reframing it. Thus, we aim at shedding light on the ways in which aspects of the political discourses on Lusophony are used (and are instrumental) to the migrants’ identity narrative (re)construction.This work was supported by Fundacao para a Ciencia e a Tecnologia: [Grant Number PTDC/CCI-COM/105100/2008]
Finite-dimensional pointed Hopf algebras with alternating groups are trivial
It is shown that Nichols algebras over alternating groups A_m, m>4, are
infinite dimensional. This proves that any complex finite dimensional pointed
Hopf algebra with group of group-likes isomorphic to A_m is isomorphic to the
group algebra. In a similar fashion, it is shown that the Nichols algebras over
the symmetric groups S_m are all infinite-dimensional, except maybe those
related to the transpositions considered in [FK], and the class of type (2,3)
in S_5. We also show that any simple rack X arising from a symmetric group,
with the exception of a small list, collapse, in the sense that the Nichols
algebra of (X,q) is infinite dimensional, for q an arbitrary cocycle.
arXiv:0904.3978 is included here.Comment: Changes in version 7: We eliminate the Subsection 3.3 and references
to type C throughout the paper. We remove Lemma 3.24, Proposition 3.28 and
Example 3.29 (old numbering), since they are not needed in the present paper.
Several minor mistakes are corrected. The proof of Step 2 in Theorem 4.1 is

Prevalence of antibodies against some abortifacient infections of dairy cattle in Uruguay
Se analizaron anticuerpos contra el virus de la diarrea viral bovina y de la rinotraqueitis infecciosa bovina, Neospora caninum y Chlamydophila abortus, en vacunos de 9 tambos del Departamento de San José, Uruguay, mediante equipos comerciales de ELISA.
La prevalencia de anticuerpos específicos fue de 76 y 65,3 % para 1080 sueros examinados para las infecciones virales respectivamente, 29,3% para neosporosis, y 10,22 % para 420 sueros examinados para clamidiosis. La comparación de las prevalencias de la infección a N. caninum entre las terneras y las vacas, permitió asumir que la principal vía de infección en este caso, fue la vertical.Sera from milking cows from 9 dairy farms from the county of San José, Uruguay, were tested with a commercial ELISA test for determination of antibodies against bovine viral diarrhea, bovine rhinotracheitis, neosporosis and chlamydiosis. The prevalence of specific antibodies was 76 and 65,3 % for 1080 sera examined for the viral infections respectively, 29.3% for neosporosis and 10.23% for 420 sera examined for chlamydiosis. Comparison of the prevalence of Neospora infection between heifers and cows, allowed to assume that the main route of transmission was vertical.Facultad de Ciencias Veterinaria
