The Xícaras from Don Hilarion: the public spaces and private homes in the eighteenth century rural
2012
El inventario post mortem y el libro de cuenta y razón del escribano Hilarión Cardona nos proporcionan una abundante información sobre las formas de vida y las actividades de este singular personaje y de su entorno. A su ascenso económico y social ayudará una estudiada política matrimonial, lo que le permitirá hacerse un hueco destacado entre los miembros de la oligarquía local. Lo nutrido y excepcional de su vestuario, junto con la posesión de novedosos objetos, nada comunes al resto de los inventarios de bienes, nos ofrecen una clara imagen del proceso de trasferencia de las formas de vida entre la ciudad y el medio rural. Hilarión sintetiza la emulación de los hábitos de comportamiento d…
Pressure-induced phase transformation in zircon-type orthovanadate SmVO4from experiment and theory
2016
The compression behavior of zircon-type samarium orthovanadate, SmVO4, has been investigated using synchrotron-based powder x-ray diffraction and ab-initio calculations up to 21 GPa. The results indicate the instability of ambient zircon phase at around 6 GPa, which transforms to a high-density scheelite-type phase. The high-pressure phase remains stable up to 21 GPa, the highest pressure reached in the present investigations. On pressure release, the scheelite phase is recovered. Crystal structure of high-pressure phase and equations of state (EOS) for the zircon- and scheelite-type phases have been determined. Various compressibilities such as bulk, axial and bond, estimated from the expe…

Pressure-Induced Transformations in PrVO4 and SmVO4 and Isolation of High-Pressure Metastable Phases
2013
Zircon-type PrVO4 and SmVO4 have been studied by high-pressure Raman spectroscopy up to 17 GPa. The occurrence of phase transitions has been detected when compression exceeds 6 GPa. The transformations are not reversible. Raman spectra of the high-pressure phases show similarities with those expected for a monazite-type phase in PrVO4 and a scheelite-type phase in SmVO4.The high-pressure phases have been also synthesized using a large-volume press and recovered at ambient conditions. X-ray diffraction measurements of the metastable products recovered after decompression confirms the monazite (PrVO4) and scheelite (SmVO4) structures of the high-pressure phases. Based upon optical properties …
High-pressure phase transformations in NdVO4 under hydrostatic, conditions: a structural powder x-ray diffraction study
2019
Room temperature angle dispersive powder x-ray diffraction experiments on zircon-type NdVO4 were performed for the first time under quasi-hydrostatic conditions up to 24.5 GPa. The sample undergoes two phase transitions at 6.4 and 19.9 GPa. Our results show that the first transition is a zircon-to-scheelite-type phase transition, which has not been reported before, and contradicts previous non-hydrostatic experiments. In the second transition, NdVO4 transforms into a fergusonite-type structure, which is a monoclinic distortion of scheelite-type. The compressibility and axial anisotropy of the different polymorphs of NdVO4 are reported. A direct comparison of our results with former experime…
Theoretical and experimental study of the structural stability ofTbPO4at high pressures
2010
We have performed a theoretical and experimental study of the structural stability of terbium phosphate at high pressures. Theoretical ab initio total-energy and lattice-dynamics calculations together with x-ray diffraction experiments have allowed us to completely characterize a phase transition at {approx}9.8 GPa from the zircon to the monazite structure. Furthermore, total-energy calculations have been performed to check the relative stability of 17 candidate structures at different pressures and allow us to propose the zircon {yields} monazite {yields} scheelite {yields} SrUO{sub 4}-type sequence of stable structures with increasing pressure. In this sequence, sixfold P coordination is …
High-pressure structural investigation of several zircon-type orthovanadates
2009
Room temperature angle-dispersive x-ray diffraction measurements on zircon-type EuVO4, LuVO4, and ScVO4 were performed up to 27 GPa. In the three compounds we found evidence of a pressure-induced structural phase transformation from zircon to a scheelite-type structure. The onset of the transition is near 8 GPa, but the transition is sluggish and the low- and high-pressure phases coexist in a pressure range of about 10 GPa. In EuVO4 and LuVO4 a second transition to a M-fergusonite-type phase was found near 21 GPa. The equations of state for the zircon and scheelite phases are also determined. Among the three studied compounds, we found that ScVO4 is less compressible than EuVO4 and LuVO4, b…
Latvian Migrants in Great Britain: ‘The Great Departure’, Transnational Identity and Long Distance Belonging
2019
AbstractThis chapter explores the transnational aspects of identity and the long distance belonging of Latvian migrants in Great Britain. In particular, it focuses on the discourses and practices of long distance belonging to Latvia. The article is based on a comparative analysis of The Emigrant Communities of Latvia survey data as well as semi-structured interviews with Latvian migrants in Great Britain. The analytical sections are organised so as to discuss the three main analytical contexts of long distance belonging: ethno-cultural, political and social. In the ethno-cultural context, migrants who identify themselves as ethnic Latvians rediscover and strengthen their links to the Latvia…
Judges, Politics and Democracy: A Discursive Analysis of the Judicial Elite during the Weimar Republic and post-WWII Germany
2014
Die personelle Kontinuität innerhalb der Justiz und der juristischen Eliten über die drei Regimewechsel hinaus, die Deutschland in der ersten Hälfte des Jahrhunderts erlebte, wurde bereits breit erforscht. Um die Entwicklung dieser Eliten in der Weimarer Republik und der frühen Nachkriegszeit zu analysieren, geht deshalb der vorliegende Beitrag nicht von den Personen, sondern von den Diskursen aus. Aus den damaligen leidenschaftlichen Debatten um die Justiz und insbesondere den Richter sticht eine zentrale, wiederkehrende Frage hervor: sollte der Übergang zur Demokratie zu einer Neubestimmung der Stellung, Funktion und Arbeit des Richters führen, und wenn ja in welchem Sinne? In der Weimare…
Multiproxy dietary trait reconstruction in Pleistocene Hippopotamidae from the Mediterranean islands
2019
Abstract Geographically isolated insular species face energetic restrictions and commonly evolve adaptations that distinguish them from their mainland ancestors. During the Pleistocene, several Mediterranean islands were inhabited by now extinct Hippopotamidae. They underwent diverse changes in locomotion, dentition and body size. Based on these differences, it is supposed that they occupied different ecological niches depending on their respective faunal complexes and available resources. In this paper, we assess the paleoecology of dwarfed hippopotami from Crete, Malta, Sicily and Cyprus using a novel dental multiproxy approach. We applied dental topography analysis (SAGA-GIS) to measure …
