Stages for the More Sustainable Farm
No full textCurrently, agricultural farm units are faced with a double and most times contradictory challenge, in order to be successful: on the one hand the invested capital has to be profitable and the economic performance has to be maximised. On the other hand, given the socio-environmental situation, it is necessary to preserve and to protect the environment and natural resources. Given the potential conflict of the two aims, since the satisfaction of one implies the underperformance of the other (and vice versa), the question then is: which is the solution to choose? We intend, in this work, to formulate a farm plan with the purpose of reconciling the criteria of environmental sustainability with that of economic competitiveness. For this achievement we proceed to the comparative study of sustainability of different groups of farms identified in the study area (first evaluation cycle) through MESMIS (“Marco para la Evaluación de Sistemas de Manejo de Recursos Naturales Mediante Indicadores de Sustentabilidad” - Framework for Evaluation of Natural-Resource Systems Handling through Sustainability Indicators) methodology, that allowed to select the more sustainable group of farms. Based on the found potentialities and weakness on these production systems, we stepped to the planning of a production unit of bovine meat, which obeys simultaneously to economic and environmental objectives, using Multicriteria Decision. We finished the work with the sustainability evaluation between groups of farms identified previously and the planned farms (second evaluation cycle), based, again, in the MESMIS methodology, to confirm (or not) the greatest sustainability of the last ones. Analyses of the results allow us to confirm the greatest relative sustainability of the planned farm, for the diverse traced scenarios.Decision taking, planning, sustainability, Environmental Economics and Policy, Farm Management,

TRAGIC NOISE AND RHETORICAL FRIGIDITY IN LYCOPHRON'S ALEXANDRA
No full textAbstract This paper seeks to shed fresh light on the aesthetic and stylistic affiliations of Lycophron's Alexandra , approaching the poem from two distinct but complementary angles. First, it explores what can be gained by reading Lycophron's poem against the backdrop of Callimachus’ poetry. It contends that the Alexandra presents a radical and polemical departure from the Alexandrian's poetic programme, pointedly appropriating key Callimachean images while also countering Callimachus’ apparent dismissal of the ‘noisy’ tragic genre. Previous scholarship has noted links between the openings of the Aetia and of the Alexandra , but this article demonstrates that this relationship is only one part of a larger aesthetic divide between the two poets: by embracing the raucous acoustics of tragedy, Lycophron's poem offers a self-conscious and agonistic departure from Callimachus’ aesthetic preferences. Second, this article considers another way of conceiving the aesthetics of the poem beyond a Callimachean frame, highlighting how Lycophron pointedly engages with and evokes earlier Aristotelian literary criticism concerning the ‘frigid’ style: the Alexandra constructs its own independent literary history centred around the alleged name of its author, ‘Lycophron’. The article proposes that this traditional attribution is best understood as a pen name that signposts the poem's stylistic affiliations, aligning it not so much with the Ptolemaic playwright Lycophron of Chalcis but rather with Lycophron the sophist and a larger rhetorical tradition of stylistic frigidity. Ultimately, through these two approaches, the article highlights further aspects of the Alexandra 's aesthetic diversity
Teaching empathy and emotions : J. M. Coetzee's "The lives of animals" and human-animal studies
No full textIn "Teaching Empathy and Emotions: J. M. Coetzee's 'The Lives of Animals' and Human-Animal Studies," Alexandra Böhm focuses on one of the most influential novels in the field of HAS. In her article, she delineates the two main difficulties in teaching Coetzee's text: firstly, the text's protagonist, fierce and fearless Australian author Elizabeth Costello, is often less-than-lovable and offers few grounds for identification; secondly, the text's multilayered structure further problematizes the authorial voice. However, by focusing on Costello's reassessment of emotion and empathy, Böhm convincingly demonstrates that Coetzee's text offers possibilities for understanding the key concepts of HAS, such as animal agency, alterity, and the necessity of assuming a non-anthropocentric perspective. In the narrative, Costello employs empathy in her approach to animals, but is this also true of the metadiegetic level of Coetzee's text? Does the text itself suggest how to teach empathy? Alexandra Böhm demonstrates that it is possible to elicit affective responses to these questions through emotion journals and role-playing
High pressure synthesis and study of ternary ruthenates
No full textMetal oxides containing ruthenium have a surprisingly varied range of low-temperature
physical properties including the superconductor Sr2RuO4 and the metallic ferromagnet
SrRuO3. The exceptionally broad manifold of itinerate and localised electronic
phenomena is derived from broad Ru 4d bands and a wide number of Ru and O
containing crystallographic structures. High-pressure is a powerful tool for manipulating
crystal structures and tuning the associated electronic and magnetic properties. In this
body of work, pressure has been utilised in two roles for the study of ternary ruthenates
with perovskite and pyrochlore structures; as a synthetic method and for in situ studies
(crystallographic or physical) of existing compounds.
Chapter 3 details pressure dependent changes in the crystal structure of the perovskite
PbRuO3 by powder x-ray diffraction up to 46 GPa and down to 20 K. PbRuO3
transformed on cooling, from orthorhombic spacegroup (Pnma) to an orbitally ordered
low temperature phase, which is also an orthorhombic space group (Imma) and applied
pressure reduced the critical temperature totally inhibiting the transition at 5.5 GPa.
Additionally PbRuO3 was found to undergo a reversible pressure induced structural phase
transition at 30 GPa and 290 K with a 10 % reduction in unit-cell volume. Indexing
indicated an orthorhombic symmetry with a Pnna spacegroup. Pnna is not a spacegroup
associated with perovskite or related perovskite structures despite the √2 x 2 x √2
perovskite superstructure being maintained across the transition. high-pressure resistivity
and Raman measurements indicated that a metal-insulator transition accompanied the
structural transition.
In Chapter 4 high-pressure high-temperature (HP-HT) synthesis has been used to isolate
dense phases that could not be produced at ambient pressure. The ortho-perovskite
LaRuO3 with space group Pnma (# 62) was synthesised by conventional solid state
methods. However to extend the series by substituting the smaller rare-earth cations, Ln3+
on the A-site of the same perovskite structure HP-HT (10 GPa and 1200° C) conditions
were required. A powder diffraction study confirmed the Pnma structure of LnRuO3
where, Ln = Pr, Nd, Sm, Eu, Gd, Dy and Ho, of which the later rare-earth compounds,
where Ln = Sm to Ho have not been synthesised before. Neutron powder diffraction
studies of LnRuO3 where Ln = La, Pr and Nd down to 7 K suggests a ~ 10 % non-stoichiometry
on the Ru site, leading to the adjusted formula LnRu0.9O3 with an unusually
low Ru3.3+ valency. A possible exception to the low Ru oxidation state is EuRuO3, which
has a larger unit-cell, suggesting a Eu2+Ru4+O3 charge distribution with the more common
Ru4+, however, this is not concordant with magnetisation measurements. Additionally
neutron diffraction suggests that the RuO6 octahedra are distorted by spin-orbit coupling.
Magnetometry and resistivity measurements indicate that the compounds are
semiconducting paramagnets down to 7 K.
Finally in Chapter 5 is presented the analysis of a high-pressure powder x-ray diffraction
experiment of the pyrochlore Tl2Ru2O7. Carried out at synchrotron facilities, we have
extended the pressure-temperature phase diagram to 3.7 GPa and 25 K. Previously it had
been reported that, when cooled, Tl2Ru2O7 undergoes a structural phase transition from a
cubic (Fd-3m) phase to a low temperature, orthorhombic (Pnma) phase that forms
Haldane chains - an unusual one-dimensional orbital ordering. As for PbRuO3
high-pressure conditions are found to inhibit the orbital ordering, to reduce the critical
temperature and to suppress the transition at pressures exceeding 3.0 GPa
Addressing the challenges of climate change risks and adaptation in coastal areas: A review
No full textClimate change is and will continue altering the world's coasts, which are the most densely populated and economically active areas on earth and home for highly valuable ecosystems. While there is considerable relevant research, in the authors' experience this problem remains challenging for coastal engineering. This paper reviews important challenges in this respect and identifies three key actions to address them: (a) refocusing traditional practice towards more climate-aware approaches; (b) developing more comprehensive risk frameworks that include the multi-dimensionality and non-stationarity of their components and consideration of uncertainty; and (c) building bridges between risk assessment and adaptation theory and practice. We conclude that the way forward includes numerous activities including increased observations; the attribution of coastal impacts to their drivers; enhanced climate projections and their integration into impact models; more impact assessments at the local scale; dynamic projections of spatially-distributed exposure and vulnerability; and the exploration of inherently adaptive options. Given the complexity of the possible solutions, more practical guidance is required.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Coastal Engineerin
