Towards sustainability in European agricultural firms
European agricultural activity plays an important role in European and world food security through the agricultural production, supply and international trade. The main aim of this paper was analyses the agricultural sustainability of the twenty-nine Member States of the European Union in terms of economics, environmental, social and political activity. Information and data comes from FADN database from the European Commission. The methodology includes the min-max approach and multivariate methods, namely, Component Principal Analysis and Cluster analysis. The results confirm three groups of European countries, namely, the North and Central countries; the New Member States and the Mediterranean counties. The results also confirm that European agriculture firms and respective countries had a medium sustainability. The main conclusion highlines confirms the importance of the sustainability as a tool to better adjust agricultural policies among the European Member States.info:eu-repo/semantics/acceptedVersio
Global phase portraits of a predator-prey system
We classify the global dynamics of a family of Kolmogorov systems depending on three parameters which has ecological meaning as it modelizes a predator–prey system. We obtain all their topologically distinct global phase portraits in the positive quadrant of the Poincaré disc, so we provide all the possible distinct dynamics of these systems
Dynamics of a two prey and one predator system with indirect effect
Altres ajuts: Consellería de Educación, Universidade e Formación Profesional (Xunta de Galicia), grant ED431C 2019/10We study a population model with two preys and one predator, considering a Holling type II functional response for the interaction between first prey and predator and taking into account indirect effect of predation. We perform the stability analysis of equilibria and study the possibility of Hopf bifurcation. We also include a detailed discussion on the problem of persistence. Several numerical simulations are provided in order to illustrate the theoretical results of the paper
Proizvodnja ksilitola iz hidrolizata eukaliptusova drva u jeftinim fermentacijskim podlogama
Several aspects concerning the bioconversion of xylose-containing hydrolysates (obtained from Eucalyptus wood) into xylitol were assessed. Debaryomyces hansenii yeast strains were adapted to fermentation media (obtained either by prehydrolysis or autohydrolysis- posthydrolysis of wood) supplemented with low-cost nutrients. Media containing up to 80 g/L xylose were efficiently fermented when the hydrolysates were detoxified by charcoal adsorption and supplemented with corn steep liquor.Ispitano je nekoliko mogućnosti biokonverzije ksiloze iz hidrolizata, dobivenih iz eukaliptusova drva, u ksilitol. Sojevi Debaryomyces hansenii adaptirani su na fermentacijske podloge (dobivene predhidrolizom ili autohidrolizom-posthidrolizom drva) uz jeftine hranjive dodatke. Fermentacija je bila uspješna u podlozi s 80 g/L ksiloze ako su hidrolizati bili detoksificirani adsorpcijom na aktivnom ugljenu uz dodatak kukuruznog ekstrakta (CSL)
Analysing the Trump and Brexit voters
This paper refers to two recent political phenomena: the Brexit, separation of the United Kingdom from the European Union, and the election of Donald Trump as President of the United States. It is important to note that the results on both occasions did not meet the expectations based on opinion polls, on one hand, and, on the other, seemed to be influenced by the adoption of populist attitudes by some of the people and parties involved. It is therefore necessary to deepen the knowledge about the two situations, their fundamentals and their outcomes. That is the objective of this paper. To gather published information and try to use it for the understanding of the results based on existing theories and thoughts.info:eu-repo/semantics/publishedVersio
Physiotherapy in Smith-Magenis syndrome: a case report
[Resumen] El síndrome de Smith-Magenis es una alteración del desarrollo psicomotor de origen genético, incluido en el grupo de enfermedades raras. En el caso clínico que se presenta, se realizó una valoración inicial de la coordinación, la marcha y el equilibrio a través del test de desarrollo psicomotor (TEPSI), un circuito diseñado específicamente, la prueba del tablero de clavijas de Purdue y el test Timed up and Go. Al finalizar los 3 meses que duró el tratamiento, basado en actividades de tipo lúdico, se realizó una valoración final con las mismas pruebas, encontrándose importantes diferencias objetivas en los resultados obtenidos, además de una mejoría subjetiva reportada por los padres del paciente. A pesar de que la evidencia sobre el tratamiento de fisioterapia en este síndrome es escasa, atendiendo a los resultados encontrados creemos que dicho tratamiento está totalmente justificado en el abordaje integral de los pacientes que lo padecen.[Abstract] The Smith-Magenis syndrome is a genetic psychomotor development disorder included in the group of rare diseases. In the clinical case presented, we performed an initial assessment of coordination, gait and balance using four different tests. These were psychomotor development test (TEPSI scale), Purdue pegboard, time up and go test, and a circuit designed specifically for this clinical case. At the end of the 3 months of treatment, and based on recreational type activities, a final assessment was made with the same tests. Significant objectives differences in the results as well as subjective improvement reported by the patient's parents were found. Although there is little evidence on physiotherapy treatment for this syndrome, in accordance with the results found, we believe that this treatment is totally justified in the comprehensive approach to patients suffering this disorder
Climate fluctuations during the Holocene in NW Iberia: high and low latitude linkages
International audienceHigh resolution benthic foraminiferal oxygen and carbon stable isotopes (?18O, ?13C) from core EUGC-3B are used here to infer rapid climatic changes for the last 8500 yr in the Ría de Muros (NW Iberian Margin). Benthic foraminiferal ?18O and ?13C potentially register migrations in the position of the hydrographic front formed between two different intermediate water masses: Eastern North Atlantic Central Water of subpolar origin (ENACWsp), and subtropical origin (ENACWsp). The isotopic records have been compared with two well established North Atlantic marine Holocene paleoceanographic records from low (Sea Surface Temperatures anomalies off Cape Blanc, NW Africa) and high latitudes (Hematite Stained Grains percentage, subpolar North Atlantic). This comparison clearly demonstrates that there is a strong link between high- and low-latitude climatic perturbations at centennial-millennial time scales during the Holocene. Spectral analyses also points at a pole-to-equator propagation of the so-called 1500 yr cycles. Our results demonstrate that during the Holocene, the NW Iberian Margin has undergone a series of cold episodes which are likely triggered at high latitudes in the North Atlantic and are rapidly propagated towards lower latitudes. Conceivably, the propagation of these rapid climatic changes involves a shift of atmospheric and oceanic circulatory systems and so a migration of the hydrographical fronts and water masses all along the North Atlantic area
Physical Activity, Quality of Live and Well-Being in Individuals with Intellectual and Developmental Disability
The practice of physical activity, exercise and sport has many benefits for the general population, but studies on the population with intellectual and developmental disabilities (IDD) are scarce and inconclusive. The aim of this systematic review is to analyze the state of the art on the role of physical activity, exercise and sport in the quality of life and well-being of people with IDD, seeking to understand the current panorama in this area and provide answers to these questions. The research was carried out between July and October 2023 using three databases: PubMed, Web of Science and Scopus. Fifteen articles met the eligibility criteria for this study, and these were methodologically assessed using the Downs and Black scale (1998). Higher values were identified in the total quality of life score and some domains of this variable (e.g., personal development, physical well-being and emotional well-being), in satisfaction with life and in the perception of well-being in individuals with IDD who have enjoyed or are involved in physical activity, physical exercise and/or sports programs. Thus, according to the studies included in this systematic review, we can conclude that the practice of physical activity, physical exercise and sport seems to contribute to improving the quality of life and well-being of people with IDD. Despite the growing research interest in this area, there is still a notable lack of studies exploring the impact of these programs, especially sports-based programs, on quality of life and well-being variables in the population under study.info:eu-repo/semantics/publishedVersio
SEOM-GECP-GETTHI Clinical Guidelines for the treatment of patients with thymic epithelial tumours (2021)
Chemotherapy; Lenvatinib; Thymic epithelial tumoursQuimioterapia; lenvatinib; Tumores epiteliales tímicosQuimioteràpia; Lenvatinib; Tumors epitelials tímicsThymic epithelial tumours (TET) represent a heterogeneous group of rare malignancies that include thymomas and thymic carcinoma. Treatment of TET is based on the resectability of the tumour. If this is considered achievable upfront, surgical resection is the cornerstone of treatment. Platinum-based chemotherapy is the standard regimen for advanced TET. Due to the rarity of this disease, treatment decisions should be discussed in specific multidisciplinary tumour boards, and there are few prospective clinical studies with new strategies. However, several pathways involved in TET have been explored as potential targets for new therapies in previously treated patients, such as multi-tyrosine kinase inhibitors with antiangiogenic properties and immune checkpoint inhibitors (ICI). One third of patient with thymoma present an autoimmune disorders, increasing the risk of immune-related adverse events and autoimmune flares under ICIs. In these guidelines, we summarize the current evidence for the therapeutic approach in patients with TET and define levels of evidence for these decisions
