Enfermar lejos de casa : la atención médica y veterinaria en los hostales de la Corona de Aragón durante la Baja Edad Media
2013
During the late Middle Ages the mobility of people was intense, for various reasons. Frequently, people stayed in hostels, which were abundant in all cities and in the countryside and where they could rest, eat and receive medical care for themselves and their horses. These hostels were favourable environments to the intervention of barbers and surgeons, because many fights resulting in injuries took place there.Durante la baja Edad Media la movilidad de las personas fue muy intensa, por razones diversas. Frecuentemente la gente se alojaba en hostales, abundantes en todas las ciudades y también en el mundo rural, donde podían descansar, alimentarse y recibir atención médica para ellos y par…
Mössbauer Spectroscopy: Elegance and versatility in chemical diagnostics
2010
Dedicated to Professor Rudolf Ludwig Mossbauer on the occasion of his 80th birthday . Soon after the discovery of the recoilless nuclear resonance fluorescence by Rudolf L. Mossbauer some fifty years ago a new spectroscopic technique developed quickly on the basis of this resonance phenomenon as an excellent tool for the investigation of materials through electric and magnetic hyperfine interactions between electrons and suitable Mo uml ssbauer nu-clides. Many disciplines of solid state research have benefited from applications of the new tool for non-destructive phase analysis. Chemists in particular have recognized the information that can be derived from Mo uml ssbauer spectra regarding …
In-situ Mössbauer Spectroscopy with MIMOS II at Rio Tinto, Spain
2010
The Rio Tinto, located in southwest Spain, exhibits a nearly constant, acidic pHvalue along its course. Due to the formation of sulfate minerals, Rio Tinto is considered a potential analogue site for sulfate-rich regions on Mars, in particular at the landing site of the Mars Exploration Rover Opportunity, where the ferric sulfate mineral jarosite was identified with Opportunity's Mössbauer spectrometer. Primary and secondary mineralogy was investigated in situ with portable Raman and Mössbauer spectrometers at four different Rio Tinto sampling sites. The two techniques analyse different sample portions due to their specific field of view and sampling depth and provide complementar…
An environmental forensic procedure to analyse anthropogenic pressures of urban origin on surface water of protected coastal agro-environmental wetla…
2013
Detection and spatial distribution of 14 drugs of abuse and 17 pharmaceuticals in surface waters was investigated to determine transport hydrological connectivity between urban, agriculture and natural environments. Solid-phase extraction and liquid chromatography tandem mass spectrometry was applied to all samples. To determine spatial incidence of contaminants, analytical results of target compounds were georeferenced and integrated into a geographical information systems structure together with layers of municipal population, location of sewage water treatment plants and irrigation channels and sectors. The methodology was applied to L'Albufera Natural Park in Valencia (Spain). A total o…
