Effect of lithium ions on the catalytic efficiency of calcium oxide as a nanocatalyst for the transesterification of lard oil
2019
The present work encompasses the effect of Li+ ions on CaO nanoparticles for the transesterification of lard oil. The modification of CaO nanoparticles was achieved by the impregnation of different molar ratios of lithium hydroxide. Later, each catalyst was screened for the catalytic conversion of lard oil to a fatty acid methyl ester (FAME). The nanocatalyst CaO–0.5LiOH (1 : 0.5 molar ratio) showed the best conversion rate for FAME. The synthesized nanocatalyst was characterized using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), Brunauer–Emmett–Teller (BET) analysis, and Hammett indicato…
Service-learning in the Spanish university system : a study based on deans’ perception
2019
Título, resumen y palabras clave en español e inglés Resumen basado en el de la publicación Disponible la versión en inglés La tercera misión de la universidad implica devolver a la sociedad parte de lo que de ella recibe. Este modo de entender la relación entre sociedad y universidad supone la implementación de nuevas metodologías de enseñanza-aprendizaje, en las cuales el profesorado deja de ser un mero transmisor de conocimiento y los estudiantes adquieren un papel activo y crítico en respuesta a las necesidades sociales. El aprendizaje-servicio es una estrategia metodológica que combina la formación teórica en un ámbito de conocimiento con su aplicación a través de la prestación de un s…
Localizing Global Solidarity: Humanitarian Aid in Lesvos
2021
The so-called “refugee crisis” in Lesvos, Greece provides a poignant example of situated, local suffering that has called for the coordination of global resources to provide relief. Some of the first to respond were local and international Citizen Initiatives for Global Solidarity (CIGS). While a growing role for CIGS has been interpreted as a call for more global involvement, arguments for the increased localization of relief efforts suggest the need for aid agents to maintain a reflexive awareness of the potential for an influx of outside assistance to disempower those most affected. We argue that barriers to implementing the localization of humanitarian aid can be better understood by po…

The experience of risk in families: conceptualisations and implications for transformative consumer research
2014
International audience; Families represent an important context for understanding and addressing the various forms of risk experienced by consumers. This article defines and discusses the concept of risk as it applies to the familial unit, with a particular focus on the liminal transitions that occur within families and the resiliency required for families to identify and adopt effective coping strategies to manage these transitions. A framework is proposed that offers researchers an approach for applying concepts related to family risk to various consumption-related problems and issues. This framework constitutes a starting point that can be developed and expanded to facilitate a deeper un…
A fast hierarchical dual boundary element method for three-dimensional elastodynamic crack problems
2010
In this work a fast solver for large-scale three-dimensional elastodynamic crack problems is presented, implemented, and tested. The dual boundary element method in the Laplace transform domain is used for the accurate dynamic analysis of cracked bodies. The fast solution procedure is based on the use of hierarchical matrices for the representation of the collocation matrix for each computed value of the Laplace parameter. An ACA (adaptive cross approximation) algorithm is used for the population of the low rank blocks and its performance at varying Laplace parameters is investigated. A preconditioned GMRES is used for the solution of the resulting algebraic system of equations. The precond…
A CUDA-based implementation of an improved SPH method on GPU
2021
We present a CUDA-based parallel implementation on GPU architecture of a modified version of the Smoothed Particle Hydrodynamics (SPH) method. This modified formulation exploits a strategy based on the Taylor series expansion, which simultaneously improves the approximation of a function and its derivatives with respect to the standard formulation. The improvement in accuracy comes at the cost of an additional computational effort. The computational demand becomes increasingly crucial as problem size increases but can be addressed by employing fast summations in a parallel computational scheme. The experimental analysis showed that our parallel implementation significantly reduces the runti…
At the Interface of National and Transnational: The Development of Finnish Policies against Domestic Violence in Terms of Gender Equality
2017
Although gender inequalities are the main social mechanisms behind the (re)production of domestic violence, policy responses to domestic violence as a gender-related problem vary at both the national and transnational levels. This article examines the interaction between national and transnational policies against domestic violence, focusing on how domestic violence is constructed as a gender-related problem in Finland, a Nordic welfare state that is often cited as a role model in gender equality. Using the conception of policies as historically changing and culturally specific discourses, this article offers an overview of the ways in which the perspective on domestic violence of the trans…
La suprema giurisdizione nella Sardegna moderna. Travagli della Real Audiencia (1564-1651)
2019
The institution of the Real Audiencia in the kingdom of Sardinia since the 1560s is part of a wider process which saw the rise and development of royal supreme courts of justice in several European countries of the early modern period. In fact, major State formation processes all around Europe required that monarchs increased their control on local authorities and that new increasingly centralised systems of judicial review gained precedence over all particular jurisdictions, feudal as well as municipal. This brought about a dramatic transformation in the field of criminal law enforcement and administration of justice.
Nāve un transformācija Džuandzi filozofijā
2016
Bakalaura darba tēma “Nāve un transformācija Džuandzi filozofijā” ir veltīta Džuandzi, vienam no ievērojamākajiem daoisma filozofiem, viņa skatpunkta par nāvi un transformāciju izpētei. Darba mērķis ir, balstoties uz pieejamiem materiāliem, izpētīt Džuandzi skatpunktu, kas notiek pēc tā brīža, kad cilvēks neizrāda nekādas dzīvības pazīmes, un kā uz to, pēc viņa domām, jāreaģē. Par pašu filozofu ir maz zināmas informācijas, bet tiek uzskatīts, ka viņš ir darba “Džuandzi” ideju autors. “Džuandzi” darbā ir atrodami vairāki stāsti, kuros ir iespējams vērot filozofa attieksmi pret dzīvi, nāvi un transformāciju. Tēma par transformāciju un nāvi ir īpaši aktuāla, Džuandzi bieži runā par relatīvismu…
