- Physiology of spore formation for Bacillus probiotic productionPublication . Pawar, Lokesh; Singh, Arya; Chouhan, Nayan; Amer, Hadeer A.; Likitha, K.; Prasanthmadduluri, Naga; Singh, Soibam Khogen; Soltani, MehdiProbiotic Immune response Bacillus sp Physiology of Bacillus Bacillus species are highly regarded as probiotics in aquaculture due to their positive impact on host health and disease prevention. This chapter provides a comprehensive overview of the physiological aspects and optimization strategies involved in the production of Bacillus spp. probiotics for aquaculture that contributes to the development of efficient and sustainable aquaculture practices. It highlights the significance of Bacillus spp. as probiotic, their potential in enhancing aquaculture productivity, and the importance of understanding the physiological characteristics of Bacillus spp. to optimize their growth and spore production. The chapter discusses several key factors that influence Bacillus spp. spore production and growth. It explores the effects of carbon sources, lignocellulosic growth substrates, nitrogen sources, medium pH, agitation and aeration, and microelements on the physiology and productivity of Bacillus species. Additionally, the chapter emphasizes the importance of selecting the appropriate cultivation method for scaled-up Bacillus spp. probiotic production in aquaculture. Different cultivation methods, such as batch, continuous, and fed-batch cultures, are evaluated, taking into account their impact on growth, spore formation, and overall probiotic yield. It enables the cultivation of high-quality probiotics with enhanced benefits, including disease prevention, improved nutrient utilization, and growth promotion, thereby enhancing the health and productivity of aquaculture organisms.
- Methodology for research and learning about mediterranean pasturesPublication . Ortiz, Ana Cano; Meireles, Catarina I. Rodrigues; Raposo, Mauro; Quinto Canas, Ricardo; Fuentes, José Carlos Piñar; Cano, EusebioIn the field study of Mediterranean grasslands, two types were identified, which from the edaphic point of view are classified as subnitrophilic and nitrophilic. Subnitrophilic grasslands include communities dominated by Taeniatherum caput-medusae and to a lesser extent by species of the genus Medicago sp. The second group of nitrophilic grasslands includes two subgroups: (1) those with a high percentage of Hordeum leporinum, which together with subnitrophilic grasslands have a high value for cattle and horse breeding, and as carbon sinks due to the high absorption of CO2. To subgroup (2) belong the grasslands of the Spanish dehesas and Portuguese montados, very rich in Poa bulbosa, Trifolium subterraneum, Biserrula pelecinus, considered of interest by the habitats directive and national and regional governments. Grasslands belonging to the Poetea bulbosae class are of interest for sheep farming, but not as CO2 sinks because they have a lower biomass than the subnitrophilous and nitrophilous of the Sellarietea mediae class. Considering the jaw system of the three types of livestock and the structure of the different pastures, a close correlation should be established between the type of livestock and the type of pasture. All these aspects should be known by future managers, which will enable them to defend the conservation and use of Mediterranean pastures, hence the need to teach them in Universities and Research Centers.

- Case study: water reuse in citrus farming - carbon emissions reduction and ecosystems protectionPublication . Resende, Flávia C.; Silva, Manuela Fernanda Gomes Moreira da; Anibal, Jaime; Martins, António; Duarte, AmilcarAnthropogenic 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 thingsPublication . Gomes, Ruben; Correia, NoéliaThe 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 systemsPublication . Graça, DanielIn 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 NevesThis 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 sensorPublication . SOARES, CRISTIANO; Zabel, Friedrich; Jorge Maia dos Santos, Paulo; Silva, AntónioVector 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.
