Satisfying states of triangulations of a convex n-gon

In this work we count the number of satisfying states of triangulations of a convex n-gon using the transfer matrix method. We show an exponential (in n) lower bound. We also give the exact formula for the number of satisfying states of a strip of triangles.Comment: 17 pages, 6 figure

El cuidado, parte fundamental en la esclerosis lateral amiotrófica

La Esclerosis Lateral Amiotrófica (ELA) es una enfermedad degenerativa y de curso progresivo, que afecta a la médula espinal, tronco y corteza cerebral lo que se traduce en la pérdida de la función en varios dominios. Su etiología es aún desconocida, pero se barajan distintas causas subyacentes como responsables de la enfermedad. El diagnóstico diferencial debe establecerse de manera precoz en fases iniciales, ya que permite la provisión de fármacos y ayudas, así como la comunicación acerca de la planificación de la atención. Aunque no existe un tratamiento que pueda detener o revertir su condición progresiva, el abordaje sintomático y el amplio enfoque de la gestión, a través de la colaboración de un equipo multidisciplinar, permite que las personas con ELA y sus familias vivan tan plenamente como sea posible. La base de la mejora en su calidad de vida, junto con los fármacos, son los cuidados y actividades específicas orientadas para cada persona, punto en el adquiere gran importancia la labor de enfermería. Una comprensión completa de las posibles causas, de la sintomatología, progresión y tratamiento de la ELA es esencial para brindar una atención integral, oportuna y de calidad al pacienteOtroGrado en Enfermerí

Linking land use-land cover change with annual and perennial plant growth models for the spatio-temporal explicit simulation of ecosystem services : A case study in a savanna region of Ghana

Many West African economies have been experiencing fast growth over recent decades. At the same time, their landscapes are also experiencing one of the fastest changes in the world, and the pace has accelerated over recent decades. These changes are driven both by local demands and the historical export of renewable resources. The need to satisfy the growing internal food demand has driven widespread and uncontrolled cropland expansion, whereas global concerns regarding the need to transition towards a new techno-economic paradigm based on the substitution of fossil fuels with biomass products, put additional pressures on local land use systems derived from the global competition for land. In this context, there are clear signs that many West African landscapes are experiencing a degradation of their capacities to reproduce biomass. Therefore, regional land use planning is of foremost importance to improve the satisfaction of human nutritional requirements and energy demand in the medium-term and ensure it in the long term. Land use planning processes involve an exercise of anticipating the impact that a chosen strategy may have on the achievement of certain goals. Because the future is uncertain, robust land use planning processes must explore different development pathways and rely on new simulated data. The purpose of this study is to explore how available data and one-dimensional plant growth models can be used in a spatially-explicit modeling environment to represent medium-/long-term temporal dynamics of the match between ecosystem services supply (using biomass provision as an example), and demand on a district scale. Benefits derived from the consumption of biomass have been quantified in terms of nutritional, feed and fuel yields. The prospective trends of these indicators have been simulated in a spatio-temporally explicit way under three alternative land use change pathways, in combination with different paces of technology adoption change and three projections of population growth. The methodology has been applied over a land use-land cover (LULC) map of high grain and thematic resolution covering the districts of Bolgatanga Municipal and Bongo in the interior savanna zone of Ghana. Land use transitions have been simulated within the GISCAME platform, which allows simulation of future LULC scenarios using data for which no temporal series is available. Agricultural biomass production data has been simulated on the plot-scale with the process-based crop modeling platform APSIM to analyze the production trade-offs among different cropping choices, involving groundnut, millet, sorghum, maize, rice. Additionally, woody biomass growth data has been simulated at the stand-level by fitting a logistic curve to data selected after an extensive literature review. The results show that the availability of micronutrients (iron and zinc) provided by regional agriculture shall be sufficient to satisfy the dietary requirements of the whole population, but the provision of calories is insufficient. Croplands are the land use types that provide the largest amounts of food and also fuel biomass. Therefore, scenarios with more widespread cropland expansion perform better in all of the indicators assessed. The main shortcoming of the methodology applied to inform real land use planning processes is that the spatio-temporal simulation of regulating ecosystems services was not considered. Therefore, the contribution of non-cultivated land use classes to the renewability of biomass production was not fully accounted for. Model and simulation of a wider range of land use and biomass types in spatially-explicit models would also contribute to significantly increasing the value of these studies to support land use decisions and inform better policies. Improvements across the whole chain are required to increase the efficiency in which biomass production and harvesting satisfies human demands. Integration of spatially-explicit biomass production assessments with models relevant to value chain development, such as transportation costs, could contribute to reducing the socio-ecological risks associated with socio-economic transitions

Analysis of the Behaviour of Biofuel-Fired Gas Turbine Power Plants

The utilisation of biofuels in gas turbines is a promising alternative to fossil fuels for power generation. It would lead to significant reduction of CO2 emissions using an existing combustion technology, although significant changes seem to be needed and further technological development is necessary. The goal of this work is to perform energy and exergy analyses of the behaviour of gas turbines fired with biogas, ethanol and synthesis gas (bio-syngas), compared with natural gas. The global energy transformation process (i.e. from biomass to electricity) has also been studied. Furthermore, the potential reduction of CO2 emissions attained by the use of biofuels has been determined, considering the restrictions regarding biomass availability. Two different simulation tools have been used to accomplish the aims of this work. The results suggest a high interest and the technical viability of the use of Biomass Integrated Gasification Combined Cycle (BIGCC) systems for large scale power generation

The role of the written press in the construction of division in Northern Ireland

[Abstract] This research examines the role played by the print media in the construction of social division in Northern Ireland during the years of the events known as the Troubles, a dark period in Irish history that is still latent today. For this purpose, I have chosen one of the many tragic events that occurred during that time: the killing of the Gibraltar Three, also known as Operation Flavius. This was a tragic event marked by lies, the cruelty of the state´s sewers and the dirty war that the British have been waging for centuries in Ireland. The 7 and 8 March 1988 issues of Northern Ireland's leading newspapers, two Unionist and two Nationalist, were analyzed. Among the Unionists, the News Letter, which is more conservative, and the Belfast Telegraph, which is more liberal, were analyzed too. On the other hand, among the nationalists, copies of The Irish News, a newspaper with a moderate nationalist tradition and An Phoblacht, a political newspaper published by Sinn Féinn, were also analyzed. Prior to this, a brief analysis of the Northern Irish print media system, with its political influences and interests, was carried out. All this work led to different conclusions, depending on which newspaper reported the events. The broadly affirmative conclusion was that newspapers did influence and help to construct social division in Northern Ireland. After all, as humans, we are emotional, and these emotions make us move. We could reduce our entire existence to interests, and that is what we have observed in the analysis of these diaries. In the end, they are advocating for their interests, which in turn can be the interests of a community, whether unionist or nationalist; maybe for the interest of a certain sector, perhaps from a more accommodated backgrounds who seek harmony and coexistence; or, as we have also seen, for the interest of the State. The purpose of this paper is nothing more than to remember the victims of an evil system that mistreated them for years and that removed from them their civil rights; and the victims of political violence. In order not to forget the past, so that in such gruesome times of history as we are coming in the world but also in Northern Ireland, events like this won´t be repeated. But also to defend freedom of expression and to denounce interference in the press for the purpose of alienating its readers.Traballo fin de grao (UDC.FIL).
