Políticas de Copyright de Publicações Científicas em Repositórios Institucionais: O Caso do INESC TEC

A progressiva transformação das práticas científicas, impulsionada pelo desenvolvimento das novas Tecnologias de Informação e Comunicação (TIC), têm possibilitado aumentar o acesso à informação, caminhando gradualmente para uma abertura do ciclo de pesquisa. Isto permitirá resolver a longo prazo uma adversidade que se tem colocado aos investigadores, que passa pela existência de barreiras que limitam as condições de acesso, sejam estas geográficas ou financeiras. Apesar da produção científica ser dominada, maioritariamente, por grandes editoras comerciais, estando sujeita às regras por estas impostas, o Movimento do Acesso Aberto cuja primeira declaração pública, a Declaração de Budapeste (BOAI), é de 2002, vem propor alterações significativas que beneficiam os autores e os leitores. Este Movimento vem a ganhar importância em Portugal desde 2003, com a constituição do primeiro repositório institucional a nível nacional. Os repositórios institucionais surgiram como uma ferramenta de divulgação da produção científica de uma instituição, com o intuito de permitir abrir aos resultados da investigação, quer antes da publicação e do próprio processo de arbitragem (preprint), quer depois (postprint), e, consequentemente, aumentar a visibilidade do trabalho desenvolvido por um investigador e a respetiva instituição. O estudo apresentado, que passou por uma análise das políticas de copyright das publicações científicas mais relevantes do INESC TEC, permitiu não só perceber que as editoras adotam cada vez mais políticas que possibilitam o auto-arquivo das publicações em repositórios institucionais, como também que existe todo um trabalho de sensibilização a percorrer, não só para os investigadores, como para a instituição e toda a sociedade. A produção de um conjunto de recomendações, que passam pela implementação de uma política institucional que incentive o auto-arquivo das publicações desenvolvidas no âmbito institucional no repositório, serve como mote para uma maior valorização da produção científica do INESC TEC.The progressive transformation of scientific practices, driven by the development of new Information and Communication Technologies (ICT), which made it possible to increase access to information, gradually moving towards an opening of the research cycle. This opening makes it possible to resolve, in the long term, the adversity that has been placed on researchers, which involves the existence of barriers that limit access conditions, whether geographical or financial. Although large commercial publishers predominantly dominate scientific production and subject it to the rules imposed by them, the Open Access movement whose first public declaration, the Budapest Declaration (BOAI), was in 2002, proposes significant changes that benefit the authors and the readers. This Movement has gained importance in Portugal since 2003, with the constitution of the first institutional repository at the national level. Institutional repositories have emerged as a tool for disseminating the scientific production of an institution to open the results of the research, both before publication and the preprint process and postprint, increase the visibility of work done by an investigator and his or her institution. The present study, which underwent an analysis of the copyright policies of INESC TEC most relevant scientific publications, allowed not only to realize that publishers are increasingly adopting policies that make it possible to self-archive publications in institutional repositories, all the work of raising awareness, not only for researchers but also for the institution and the whole society. The production of a set of recommendations, which go through the implementation of an institutional policy that encourages the self-archiving of the publications developed in the institutional scope in the repository, serves as a motto for a greater appreciation of the scientific production of INESC TEC

Molecular phylogeny of horseshoe crab using mitochondrial Cox1 gene as a benchmark sequence

An effort to assess the utility of 650 bp Cytochrome C oxidase subunit I (DNA barcode) gene in delineating the members horseshoe crabs (Family: xiphosura) with closely related sister taxa was made. A total of 33 sequences were extracted from National Center for Biotechnological Information (NCBI) which include horseshoe crabs, beetles, common crabs and scorpion sequences. Constructed phylogram showed beetles are closely related with horseshoe crabs than common crabs. Scorpion spp were distantly related to xiphosurans. Phylogram and observed genetic distance (GD) date were also revealed that Limulus polyphemus was closely related with Tachypleus tridentatus than with T.gigas. Carcinoscorpius rotundicauda was distantly related with L.polyphemus. The observed mean Genetic Distance (GD) value was higher in 3rd codon position in all the selected group of organisms. Among the horseshoe crabs high GC content was observed in L.polyphemus (38.32%) and lowest was observed in T.tridentatus (32.35%). We conclude that COI sequencing (barcoding) could be used in identifying and delineating evolutionary relatedness with closely related specie

Crab and cockle shells as heterogeneous catalysts in the production of biodiesel

In the present study, the waste crab and cockle shells were utilized as source of calcium oxide to transesterify palm olein into methyl esters (biodiesel). Characterization results revealed that the main component of the shells are calcium carbonate which transformed into calcium oxide upon activated above 700 °C for 2 h. Parametric studies have been investigated and optimal conditions were found to be catalyst amount, 5 wt.% and methanol/oil mass ratio, 0.5:1. The waste catalysts perform equally well as laboratory CaO, thus creating another low-cost catalyst source for producing biodiesel. Reusability results confirmed that the prepared catalyst is able to be reemployed up to five times. Statistical analysis has been performed using a Central Composite Design to evaluate the contribution and performance of the parameters on biodiesel purity

An investigation of sqrt 2 conjecture inspired drag induced vertical axis wind turbine blade

Governments and research agencies are providing support and resources to facilitate the growth of renewable energy sector (RES). Today wind turbines (WT) are the prominent form of renewable energy for direct energy harvesting. It is found that traditional Savonius wind turbine (SWT) requires design modification or integration supportive design feature in order to improve the drag attributes and power output performance. Generally conventional WTs are design to operate at high wind speed ranging from 10-15 m/s. This constrains the WT to harvest adequate power at low wind speed condition. Research shows that, design configuration adjustment and optimization has improved the efficiency in Cp. Hence, in this study drag driven WT configuration namely SWT is adapted for the construction of proposed design. The research process flow is segregated into four phases specifying the strategies utilized to carry out the investigation namely bio-hybridization, experimental fluid dynamics, computational fluid dynamics and optimization. The selected bio-elements are reconfigured and altered to fit the design problem and criteria of WT. Since the study involves analyzing and recognizing complex morphologies of bio-elements, computational based framework is utilized for the geometry extraction process namely OpenCV. The proposed drag induced wind turbine (DIWT) is a result of hybridization of two bio-elements namely nautilus spiral configured shell and barnacle marine organism. The aim of primary stage of the design process is to construct the mainframe of the WT blade shape which is extracted from a non-aerodynamic element which is Nautilus shell. The initial design is modelled with barnacles and blade morphology inspired by mathematical conjecture but without endplates. The proposed conjecture and ratio provide an alternative approach in calculating the parametric values of a geometry with regards to √2. It appears that irrational number √2 is fundamental in the creation of circle and spiral. In addition, multiple combinations of blade curvatures is also possible to be constructed with the newly found conjecture, ratio and method. Meanwhile, relative to experimental fluid dynamics procedure the rotational properties of the rotor is investigated using a digital torquemeter coordinated by Arduino. The credibility of the fabricated torquemeter is investigated by comparing the generated moment magnitude with computational numerical model which is executed in CFD. The percentage of error between computational and instrumentational torque is 15.6 %. As for CFD framework for this research, the initially proposed design is comprehensively investigated based on computational numerical model analysis conducted in Ansys CFX. Preliminary investigation indicated that the performance of the initial design is affected by the absence of endplate. The barnacle geometry and its configuration introduce early turbulence and consequently reduces the pressure drag. The reconfiguration of the design is based on the proposed optimization process. The basis of the optimization technique is the Gf which governs the drag attributes of a body relative to flow. If the researcher would like to further investigate reconfigure the existing morphology, it is required to determine the body geometric factor in order to preliminary determine the drag condition. Since Gf 1 (positive volume) minimizes the drag attributes if the orientation of the body is perpendicular the flow. It is found that the implementation of the barnacle geometry aligned perpendicular to flow effectively reduces the pressure attributes. Hence, the technique inspired for the removal of the barnacle geometry. It is found that the blockage corrected peak Cp value of the reconfigured turbine is 0.201 which is 15.4 % of deviation from the uncorrected CFD result. Hence the new corrected data of Cp is utilized to compare with available literature to measure the performance of the proposed design. It can be concluded that the optimized design improved the quality of Cp by 19.2 % in comparison to conventional SWT at λ = 0.67. Meanwhile the author also presented a novel design with shaft and adjoin blade. It is found that the optimized design outperformed both the models by 15.51 % and 6.34 % respectively. Hence, it is evident that blade morphology modification via the proposed conjecture with the presence of endplate improves the performance of the rotor in terms of rotational characteristics and power output
