Literacia da informação: Da identidade digital à visibilidade científica

As novas possibilidades de comunicação também oferecem novas oportunidades para a formação, análise e avaliação da investigação. Cientistas e investigadores usam com frequência as aplicações baseadas na web em investigação. Praticamente em todas as áreas de investigação, as ferramentas digitais converteram-se em indispensáveis; o aparecimento de novos paradigmas como o acesso aberto, as métricas alternativas e as redes sociais são um importante exemplo de como estas mudanças afetaram a forma como os estudiosos pensam no futuro das publicações académicas. Estes acontecimentos criaram novas possibilidades e novos desafios na avaliação da qualidade da investigação, ao nível dos investigadores individuais e do desenvolvimento profissional. É a este nível que a biblioteca desempenha um papel indispensável na formação de competências e habilidades informativas que se repercutirá na valorização social do profissional, na sua satisfação profissional e, em última instância, na qualidade da própria instituição. Destacam-se os aspetos mais relevantes nos novos paradigmas de comunicação e difusão científica e, a esse respeito, recomendam-se as ações mais adequadas.

Novel efficient technologies in Europe for axle bearing condition monitoring – the MAXBE project

Axle bearing damage with possible catastrophic failures can cause severe disruptions or even dangerous derailments, potentially causing loss of human life and leading to significant costs for railway infrastructure managers and rolling stock operators. Consequently the axle bearing damage process has safety and economic implications on the exploitation of railways systems. Therefore it has been the object of intense attention by railway authorities as proved by the selection of this topic by the European Commission in calls for research proposals. The MAXBE Project (http://www.maxbeproject.eu/), an EU-funded project, appears in this context and its main goal is to develop and to demonstrate innovative and efficient technologies which can be used for the onboard and wayside condition monitoring of axle bearings. The MAXBE (interoperable monitoring, diagnosis and maintenance strategies for axle bearings) project focuses on detecting axle bearing failure modes at an early stage by combining new and existing monitoring techniques and on characterizing the axle bearing degradation process. The consortium for the MAXBE project comprises 18 partners from 8 member states, representing operators, railway administrations, axle bearing manufactures, key players in the railway community and experts in the field of monitoring, maintenance and rolling stock. The University of Porto is coordinating this research project that kicked-off in November 2012 and it is completed on October 2015. Both on-board and wayside systems are explored in the project since there is a need for defining the requirement for the onboard equipment and the range of working temperatures of the axle bearing for the wayside systems. The developed monitoring systems consider strain gauges, high frequency accelerometers, temperature sensors and acoustic emission. To get a robust technology to support the decision making of the responsible stakeholders synchronized measurements from onboard and wayside monitoring systems are integrated into a platform. Also extensive laboratory tests were performed to correlate the in situ measurements to the status of the axle bearing life. With the MAXBE project concept it will be possible: to contribute to detect at an early stage axle bearing failures; to create conditions for the operational and technical integration of axle bearing monitoring and maintenance in different European railway networks; to contribute to the standardization of the requirements for the axle bearing monitoring, diagnosis and maintenance. Demonstration of the developed condition monitoring systems was performed in Portugal in the Northern Railway Line with freight and passenger traffic with a maximum speed of 220 km/h, in Belgium in a tram line and in the UK. Still within the project, a tool for optimal maintenance scheduling and a smart diagnostic tool were developed. This paper presents a synthesis of the most relevant results attained in the project. The successful of the project and the developed solutions have positive impact on the reliability, availability, maintainability and safety of rolling stock and infrastructure with main focus on the axle bearing health.

Measuring QoS in an aeronautical opportunistic network architecture with limited access to a satellite communications backhaul

We measure quality of service (QoS) in a wireless network architecture of transoceanic aircraft. A distinguishing characteristic of the network scheme we analyze is that it mixes the concept of Delay Tolerant Networking (DTN) through the exploitation of opportunistic contacts, together with direct satellite access in a limited number of the nodes. We provide a graph sparsification technique for deriving a network model that satisfies the key properties of a real aeronautical opportunistic network while enabling scalable simulation. This reduced model allows us to analyze the impact regarding QoS of introducing Internet-like traffic in the form of outgoing data from passengers. Promoting QoS in DTNs is usually really challenging due to their long delays and scarce resources. The availability of satellite communication links offers a chance to provide an improved degree of service regarding a pure opportunistic approach, and therefore it needs to be properly measured and quantified. Our analysis focuses on several QoS indicators such as delivery time, delivery ratio, and bandwidth allocation fairness. Obtained results show significant improvements in all metric indicators regarding QoS, not usually achievable on the field of DTNs.

Synonymous co-variation across the E1/E2 gene junction of hepatitis C virus defines virion fitness

Hepatitis C virus is a positive-sense single-stranded RNA virus. The gene junction partitioning the viral glycoproteins E1 and E2 displays concurrent sequence evolution with the 3′-end of E1 highly conserved and the 5′-end of E2 highly heterogeneous. This gene junction is also believed to contain structured RNA elements, with a growing body of evidence suggesting that such structures can act as an additional level of viral replication and transcriptional control. We have previously used ultradeep pyrosequencing to analyze an amplicon library spanning the E1/E2 gene junction from a treatment naïve patient where samples were collected over 10 years of chronic HCV infection. During this timeframe maintenance of an in-frame insertion, recombination and humoral immune targeting of discrete virus sub-populations was reported. In the current study, we present evidence of epistatic evolution across the E1/E2 gene junction and observe the development of co-varying networks of codons set against a background of a complex virome with periodic shifts in population dominance. Overtime, the number of codons actively mutating decreases for all virus groupings. We identify strong synonymous co-variation between codon sites in a group of sequences harbouring a 3 bp in-frame insertion and propose that synonymous mutation acts to stabilize the RNA structural backbone.

HACIA UNA GEOGRAFÍA DE REDES: UN NUEVO PARADIGMA DE ANÁLISIS ESPACIAL ALTERNATIVO AL ENFOQUE REGIONAL

En este artículo se pretende rescatar el análisis de redes independientemente del enfoque aureolar, destacando sus virtudes en un mundo globalizado, en donde cada vez más el concepto de distancia es sustituido por de tiempo, hasta llegar al extremo de que el costo, de algunos productos o la información, ya no depende de la distancia como el caso de las tarifas planas de Internet. Se aborda un enfoque teórico metodológico que cuestiona  el  análisis  regional,  debido  a  que,  éste  enfoque  en  algunos  aspectos  ya  no puede  resolver  los  problemas  que  la  sociedad  actual  demanda.   En  el  espacio  red,la noción de  localización absoluta pierde vigencia, mientras se refuerza  la  importancia de la  conexión  a  las  redes. Las metodologías  propuestas,  podrían mejorar  la  ejecución  y operación  de  las  redes    presentes  en  los planes  de  ordenamiento  del  territorio,  tan  en boga, en nuestro país. Abstract:In  this article  it  is  tried  to rescue  the analysis of networks  independently of the approach  to  aureole, emphasizing  its  virtues  in a globalized world,  in where more and more the distance concept is replaced by the time, until arriving at the end of which the cost, no  longer depends on  the distance as  the case of  the  flat  tariffs of Internet. A theoretical/ methodological approach  that questions  the regional analysis, because,  this one approach  in some aspects no longer can solve the problems that the present society demand.  In  the  space  network,  the  notion  of  absolute  location  loses  use  while  the importance  of  the  connection  to  the  networks  is  reinforced.  The  proposed methodologies  could  improve  the  boarding  of  the  present  networks  in  the  regulating plans, so in rows, our country.
