La responsabilidad patrimonial de los centros sanitarios concertados: incidencia de los aspectos procesales en la reapertura de una polémica

[Resumen] La tendencia a ampliar la legitimación en vía contencioso administrativa a fin de conseguir la ansiada exclusividad de la jurisdicción contenciosa en materia de responsabilidad de las Administraciones Públicas ha determinado un cambio de orientación jurisprudencial en una materia en el que los cambios jurisprudenciales han sido continuos. Se analiza la controversia surgida entre la Audiencia Nacional y el Tribunal Supremo y las eventuales consecuencias que se derivan del nuevo marco normativo que surge con la nueva Ley de Contratos del Sector público[Abstract] The tendency to expand «locus standi» in order to achieve the desired exclusivity of administrative jurisdiction about liability of public administrations has identified a shift in case law, in a matter in which jurisprudential changes have been continuous. Is analyzed the dispute between the National Court (Audiencia Nacional) and the Supreme Court (Tribunal Supremo) and the posible procedural consequences of the new regulatory framework raised with the new Law on Public Sector Contracts

Software tools for project management: focus on collaborative management

Today, projects involve members from different geographical areas more than any other time in history. Thus, adequate Collaborative Project Management Software (CollabPMS) solutions are needed to enable individuals and organizations to manage, communicate and work together across time and space barriers. This article describes a set of managerial and collaborative functionalities that a CollabPMS should provide to support the complexities of a distributed project effectively. Out of hundreds software packages available in the market, four were selected, ProjectLibre, Redmine, Microsoft Project 2013 and Clarizen, to assess if they have the described functionalities. Clarizen can be considered the best software for managing distributed projects, because it provides, by default, all the managerial functions and the collaborative features that support the coordinated collaboration level. ProjectLibre was the software that less stood out in this evaluation, although it provides the majority of the outlined managerial functionalities it doesn't support any level of collaboration.info:eu-repo/semantics/publishedVersio

COVID-19 exposes weaknesses in public health in the Peruvian Amazon and highlights opportunities for a One Health approach

The Amazon is home to important wildlife and a biodiversity hotspot of global importance. The ancestral knowledge kept by Indigenous communities about its fauna and flora contributes further to its irreplaceable value. The Peruvian Amazon was heavily struck by the COVID-19 epidemic with a cumulative incidence of 725, a mortality rate of 34 per 100,000 inhabitants, and a case fatality rate of 4.6% by the end of July 2020. In this work, we review scientific literature and media to trace the events that happened at the beginning of the COVID-19 epidemic in the Peruvian Amazon. Results are synthesized in three observations: (1) the evolution of the COVID-19 epidemic within the Peruvian Amazon and the response of the Peruvian health care system, (2) Confusing information about Ivermectin use for COVID-19 treatment and prevalent self-medication (3) The response of the traditional Indigenous health care system to the COVID-19 epidemic. These three observations are interdependent. There is an unexploited potential for integrative approaches linking traditional medical practices (TMP) and biomedical approaches and they may benefit from the interactions that occur between them. Synergies can also be explored between the human and animal health care sector, especially in terms of the use and stewardship of medicines. We conclude that there is a benefit of the One Health approach in the region, which can go through the common ambition to improve the integrated health of people, animals and ecosystems, facilitate the enhancement of equity and inclusion while improving access to health services and conserving biodiversity. One Health Impact Statement The Amazon region is home to wildlife flora and fauna and indigenous Amazon communities. The case presented in this work shows that an existing grassroots initiative has been reducing case fatality rates tenfold during the COVID-19 epidemic, while acting in respect towards nature and the environment, and using its resources. This is in stark contrast to the uncontrolled, ineffective self-medication with ivermectin in that same period, which may endanger the biodiversity hotspot through metabolic residues. While the current example seems to illustrate community resilience due to government negligence, it also shows the vastly unexplored potential of integrating biomedical and traditional indigenous knowledge in a solidaric and co-creative framework such as One Health

Influence of the lunar cycle on plasma melatonin, vitellogenin and sex steroids rhythms in Senegal sole, Solea senegalensis

24 p., il., y bibliografíaThe effect of the moon light cycle on plasma melatonin rhythms was examined in Senegal sole (Solea senegalensis) exposed to natural outdoor or artificial indoor lighting conditions. Furthermore, in a second experiment, the effect of the lunar cycle on vitellogenin and sex steroids (Testosterone, T; Estradiol, E2; 11-ketotestosterone, 11kt) was studied using mature individuals during reproductive season. In the first experiment, during full moon, plasma melatonin peaked at night in covered tanks (deprived of night illumination) from both outdoor (133.2 ± 12.8 pg ml-1) and indoor (190.6 ± 41.5 pg ml-1) groups. However, for fish in the open tanks, exposed to approximately 0.3 lux of illumination, nocturnal plasma melatonin was significantly reduced (p<0.05), approaching to mid-light (ML) values, (79.6 ± 7.1 and 81.8 ± 14.0 pg ml-1, for outdoor and indoor groups, respectively). During new moon a similar pattern was observed in outdoor group: fish in the covered tank showed higher melatonin values than those in the open tank, which were exposed to the near undetectable night illumination. In the second experiment, plasma sex steroid concentrations were significantly higher during the full moon compared to the new moon. In the case of females, E2 concentration reduced from 2.4 ± 0.6 to 0.4 ± 0.1 ng ml-1 between full and new moon samplings, while T decreased from 0.3 ± 0.0 to 0.2 ± 0.0 ng ml-1. Vitellogenin, however, did not show such differences between moon phases. In males, 11kt exhibited a plasma concentration of 14.3 ± 2.1 ng ml-1 during full moon and 4.7 ± 0.7 ng ml-1 during new moon while T values were 2.6 ± 0.4 and 1.0 ± 0.1 ng ml-1 for full and new moon, respectively. In conclusion, these findings pointed out the high sensitivity to moon light of the Senegal sole, which could be using the melatonin signalling to synchronize their reproduction rhythms to the lunar cycle.This work has been financed by the Spanish Ministry of Education and Science (MEC) through project Reprosolea AGL2004-07984-CO2-01/ACU to FJSV and project AGL2006-13777-C03-01 to EM.

Polymer optical fiber specklegram strain sensor with extended dynamic range

FAPESP - FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULOCNPQ - CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOCAPES - COORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL E NÍVEL SUPERIORA polymer optical fiber strain sensor with extended dynamic range is reported. The proposed algorithm resets the reference fiber status depending on the magnitude of the specklegram deviation so the correlation coefficient never saturates, yielding a continuous response over the full range for both positive and negative strains. The technique was evaluated on the measurement of axial strains using a ZEONEX core, poly(methyl methacrylate) cladding multimode fiber, presenting reproducible results with 3 x 10(-3) mu epsilon(-1) sensitivity (similar to 15 mu epsilon resolution) within a 22,600 mu epsilon interval. In contrast to the available approaches, the presented method can retrieve the strain direction and does not require intensive image processing, thus providing a simple and reliable technique for mechanical measurements using multimode optical fibers.

SUSTENTABILIDADE AGRÍCOLA NA AMAZÔNIA: 23 anos de monitoramento da agricultura em Machadinho d’Oeste - RO

O projeto de assentamento de Machadinho d’Oeste, RO, na fronteira agrícola da Amazônia Ocidental, criado há 23 anos atrás como um projeto de colonização agrícola, vem sendo acompanhado por uma equipe de pesquisadores da Embrapa Monitoramento por Satélite. Os pesquisadores acompanharam um grupo de 438 famílias de produtores rurais oriundos, principalmente, das Regiões Sul e Sudeste do país, que ocuparam lotes e praticaram atividades de produção familiar. O monitoramento é realizado por intermédio de métodos baseados na utilização de imagens de satélite, sistemas de informações geográficas (SIG) e tratamentos numéricos. A extensa base de dados tem sido utilizada para análise da evolução e diferenciação da pequena agricultura familiar em termos da produção agrícola e da manutenção de sua sustentabilidade agrícola. Procurando saber as principais razões que diferenciam evolutivamente os lotes amostrados, foram analisados os dados dos questionários respondidos por produtores entrevistados em 1986, 1989, 1996, 1999, 2002 e 2005. A evolução nos 20 anos mostra as dificuldades enfrentadas pelos pequenos agricultores familiares que praticam as atividades agrícolas e pecuárias em seus lotes, sendo que em 2005, mais da metade dos agricultores avaliados adquiriram mais de um lote que foram comprados pela melhoria da renda. O aumento da utilização da área que se destacou em 2005, em relação aos anos anteriores, foi a pastagem que encontra-se distribuída em cerca de um quarto das propriedades, gerando, através da atividade de pecuária pela criação de bovinos, grande renda para os agricultores, tanto ao longo do ano com a produção de leite, como de forma mais esporádica com a venda de bezerros, novilhos e vacas. Quanto aos cultivos houve uma diferenciação nos sistemas de produção vegetal, com a redução do cultivo de cereais e o aumento do cultivo do café. Os sistemas agropecuários vêm se caracterizando ao longo dos anos pelo emprego crescente de tecnologia e aumento de produção.Sustentabilidade agrícola, Amazônia, Agricultura Familiar, Assentamento Rural, Desenvolvimento Rural, Community/Rural/Urban Development, Environmental Economics and Policy,

Dielectric spectroscopy of natural rubber-cellulose II nanocomposites

[EN] Nanocomposite materials obtained from natural rubber (NR) reinforced with different amounts of cellulose II nanoparticles (in the range of 0 to 30 phr) are studied by dielectric spectroscopy (DS). For comparative purposes the pure materials, NR and cellulose, are also investigated. The dielectric spectra of the nanocomposites exhibit: (a) two overlapped ¿-relaxations associated respectively with the dynamic glass transitions of NR (faster process) and of the lipid present in NR; (b) a ß-relaxation associated with local chain dynamics of cellulose and (c) a relaxation process associated to the presence of traces of water in cellulose. The spectra exhibit conductivity phenomena at low frequencies and high temperatures. The samples were also studied in the dry state. An explanation is given concerning the cellulose effect on the dielectric properties of the dry and wet nanocomposites. © 2010 Elsevier B.V.All rights reserved.The authors gratefully acknowledge CICYT for Grant No. MAT2008-06725-C03-03 and Generalitat Valenciana for Grant No. ACOMP/2010/204.Ortiz Serna, MP.; Díaz Calleja, R.; Sanchis Sánchez, MJ.; Riande, E.; Numes, R.; Martins, A.; Visconte, L.

DAWRS: A Differential - Algebraic System Solver by the Waveform Relaxation Method

We investigate the concurrent solution of low-index differential-algebraic equations (DAE’s) by the waveform relaxation (WR) method, an iterative method for system integration. We present our new simulation code, DAWRS (Differential - Algebraic - Waveform Relaxation Solver), to solve DAE’s on parallel machines using the WR methods, and describe new techniques to improve the convergence of such methods. As experimental results, we demonstrate the achievable concurrent performance to solve DAE’s for a class of applications in chemical engineering
