  • Case study: water reuse in citrus farming - carbon emissions reduction and ecosystems protection
    Publication . Resende, Flávia C.; Silva, Manuela Fernanda Gomes Moreira da; Anibal, Jaime; Martins, António; Duarte, Amilcar
    Anthropogenic factors and climate change are putting increasing pressure on natural water resources, threatening habitats and biodiversity (Libutti et al.2018, Rebelo et al., 2020). Worldwide, agriculture uses around 70% of the total water used in human activities. In addition, the demand for food and animal feed production tends to increase with the growth of the world population (Parris, 2010; Becerra-Castro et al., 2015; Chartzoulakis & Bertaki, 2015; Karandish & Šimunek, 2016). Meanwhile, freshwater use has exceeded recharge levels, leading to the desiccation of water streams, and the groundwater over-extraction has promoted saline intrusion phenomena in several coastal areas, posing additional constraints to agricultural irrigation, decreasing production and lowering crop yields (Jenkins & Sugden, 2006). To face this scenario, agriculture sustainability in more vulnerable regions, such as the south of Portugal, where water scarcity is a common reality, involves the choice of an alternative water supply and more efficient irrigation systems (Fatta-Kassinos et al., 2011; Jiang et al., 2016), as well as crop selection.
  • Optimizing resource reuse in the web of things
    Publication . Gomes, Ruben; Correia, Noélia
    The Web of Things enables collecting vast amounts of data about the environment and sharing them over the Internet. Its popularity, however, has brought challenges under constrained environments, such as an increase in the number of connected devices, and a consequent additional consumption of resources, leading to the deterioration of communications and application response times. By discovering and reusing semantically equivalent Things among applications, resources may be spared and responsiveness improved. In this article, an optimization model is developed to address this issue, and both fair and unfair goals are used for performance comparison over multiple scenarios, with different levels of network connectivity, Thing equivalence and placement. Results show that the interplay between network connectivity and equivalence ratio is determinant for responsiveness improvement, and both parameters can be used for an adequate planning of which Thing hosts to reuse. Also, ensuring a fair responsiveness among applications imposes fewer reuses, particularly in low connectivity and equivalence conditions, than using unfair criteria, where some applications can benefit from high responsiveness while others don't. When a high equivalence ratio is coupled with a low connectivity degree, reuses tend to compound into fewer hosts, independently of fairness.
  • Computation with real numbers and continuous-time dynamical systems
    Publication . Graça, Daniel
    In this paper we review some results about the interconnections between computation with real numbers and continuous dynamical systems. In particular, we take two complementary approaches: (i) to use standard computational models or theories such as Turing machines or computable analysis to understand which properties of continuous dynamical systems can be computed and (ii) to use continuous dynamical systems directly as models of computation and study their computational power. We will be particularly interested in continuous dynamical systems defined with analytic ordinary differential equations and, in particular, in dynamical systems defined with polynomial ordinary differential equations.
  • Exploring the interplay between water availability and solar and wind energy potential in the Algarve (Portugal)
    Publication . Neves, Maria C.; Rui Mendonça Neves
    This work falls within the scope of the Energy-for-Water branch of the water-energy nexus and is a contribution to better understand the available water and endogenous energy resources in the Algarve region. Time series for water resource availability, solar and wind power generation potential in the Algarve between 2004 and 2014 are analyzed. Complementarity relations among their trends and seasonal cycles are identified that can improve the efficiency in use of endogenous renewable energies in groundwater pumping.
  • Comparing noise vessel azimuth tracking with a planar hydrophone array and a single vector sensor
    Publication . SOARES, CRISTIANO; Zabel, Friedrich; Jorge Maia dos Santos, Paulo; Silva, António
    Vector sensors are appealing for monitoring underwater noise due to its inherent directivity. While acoustic pressure sensors are ambiguous in all directions, vector sensors permit the aquisition of directional information through the measurement of particle velocity, which enables the possibility of azimuth tracking of underwater noise sources. The MARREAL marine observatory is a marine observatory equipped with a number of sensors and subsystems, including an acoustic acquisition system made of four hydrophones and a vector sensor. The observatory was deployed in September 2022 in Sagres, Portugal, near the Baleeira Port which is accessed by fisher boats and recreational boats. This paper shows preliminary results on azimuth estimation of boats passing in the deployment area, obtained independently with a 4- hydrophone planar array and a vector sensor. The results indicate that a single vector sensor can provide fair results on azimuth tracking of boats passing in the area. At high signal-to-noise ratio (SNR) the vector sensor is able to yield results similar to those obtained with the planar array. When the SNR is low the planar array outperforms the vector sensor with actual processing methods used.

  • Lifespan, health and metabolic diseases. Book of abstracts, IX-SPB Clinical Biochemistry Workshop
    Publication . Manuel, Aureliano; Simão, Márcio; Ferreira, Bibiana; Coelho, Ana Luísa; Simão, Sónia; Costa, Ana; Antunes, Célia; Cancela, Leonor
    The IX Clinical Biochemistry Workshop (IX-CBW) was held on January 26, 2024, at the University of Algarve (UAlg), Faro, within the scope of the Clinical Biochemistry thematic group of the Portuguese Society of Biochemistry (SPB). It was the second time in 14 years that this important Workshop on Clinical Biochemistry will be held in Faro, after the IV edition (2010), chaired by Professor Aureliano Alves. The IX Clinical Biochemistry Workshop follows previous successful Clinical Biochemistry symposia held in Porto (2003, 2006, 2008, 2016), Faro (2010), Coimbra (2012), Lisbon (2014), and Évora (2018). This interdisciplinary event aims to bring together researchers from the scientific community who enhance the interaction between Biochemistry and Clinics to present their most recent discoveries on topics such as aging, health and metabolic diseases with an emphasis on neurological, cardiovascular diseases and diabetes, among other pathologies. However, historically, this Workshop has had a high percentage of undergraduate, master's and doctoral students as participants, reflecting the interest that the event has had in scientists of the future. Students from various degrees, masters and doctorates, as well as researchers and teachers, are therefore invited to participate in the IX Clinical Biochemistry Workshop, in the simple city of Faro, where it is good to live, study and to do research! Share with us your latest research to a committed scientific community, which has shared and promoted these Workshops in this 21st century. The excellent quality expected from the presenters and their research will certainly serve as an innovative reference for the coming decades, allowing for a broader application of Clinical Biochemistry in various fields as well as promoting the quality of life of future generations.
  • Poda de Citrinos na Região Mediterrânica. Manual Técnico
    Publication . Barrote, Isabel; Neto, Luís; Guerrero, Carlos; Marques, Natália; Duarte, Amilcar
    A poda é uma prática comum em citrinos, mas que é por vezes questionada, por se tratar de uma operação dispendiosa e por as árvores não podadas terem produções razoáveis. No entanto, a poda tem provado ser de particular importância na citricultura mediterrânica, orientada para a produção de frutos para consumo em fresco. Nesta citricultura a poda permite aumentar a qualidade do fruto, a qual é altamente valorizada, pelo que a poda se torna necessária e é compensada pelo preço de venda dos frutos. A poda permite formar e controlar a copa da árvore para obter uma melhor produtividade e qualidade dos frutos e, simultaneamente, melhorar o estado sanitário da árvore e facilitar a execução de operações, como a colheita e os tratamentos fitossanitários. Neste manual, resumimos e explicamos as técnicas de poda utilizadas na citricultura mediterrânica e referimos os principais objetivos de cada tipo de poda, tendo em consideração a morfologia e a fisiologia dos citrinos. Este livro é o resultado de vários anos de trabalho em ensaios de poda realizados no Algarve e foi escrito no âmbito do Grupo Operacional “PodaCitrus - Otimização da poda em citrinos”, financiado por fundos da União Europeia, através do programa PDR2020. É, assim, o produto de um vasto trabalho de equipa, que, além dos autores, incluiu muitos agrónomos, responsáveis técnicos pelos pomares onde foram realizados os ensaios. Foi também importante a participação de agrónomos exteriores ao projeto, com quem discutimos os resultados obtidos e as técnicas de poda de citrinos praticadas nos campos. Os autores agradecem, em primeiro lugar, às empresas Frusoal, Citriaroeira, Produção Citrícola Lda, e João Santana Unipessoal, parceiras do projeto, mas também às empresas Quinta da Barragoa e Valenciagro (grupo Martinavarro) as respetivas colaborações. Pessoalmente, agradecemos a Silvino Oliveira, Angélica Mendonça, Valter Reis, Manuel Reis, Marta Afonso, Rui Antão, Tiago Guerreiro, Vera Sustelo, Luís Mendonça e Alfonso Barrau, toda a sua colaboração. Agradecemos também a Gonçalo Azinheira pela elaboração das ilustrações deste livro e a Miguel Santos pela edição de duas fotografias. Agradecemos ainda a Hugo Marques e a Vera Sustelo pela disponibilização de algumas fotografias.
  • Material vegetal e viveiros
    Publication . Reis, Mário
    A escolha do material vegetal é uma condição fundamental para o sucesso das culturas, por razões de natureza técnica e económica. Cada espécie, variedade ou cultivar apresenta exigências ambientais próprias, que permitem o seu cultivo com sucesso em condições determinadas de solo e clima, mas que noutras condições edafo-climáticas podem conduzir a resultados pouco satisfatórios.
