El impacto del Camino de Santiago en el ámbito académico: análisis de las tesis doctorales jacobeas en España Díaz de la Fuente, Silvia; Ahedo García, Virginia; Alonso Abad, Mª Pilar; Galán Ordax, José Manuel Este trabajo presenta un estudio inicial sobre el impacto del Camino de Santiago en la literatura científica, más específicamente, en las tesis doctorales. En concreto, se aporta un análisis descriptivo de los datos más significativos de todas aquellas tesis doctorales que guardan alguna relación con el Camino de Santiago y que han sido defendidas en España hasta finales del año 2021. En particular, los datos considerados incluyen el momento y lugar de defensa de cada tesis, así como sus descriptores temáticos —códigos UNESCO—. Para la recopilación de estos datos se ha consultado la base de datos TESEO, el repositorio del Ministerio de Educación, Cultura y Deporte en el que se almacenan todas las tesis doctorales españolas. Trabajo presentado en VII Jornadas de Doctorandos de la Universidad de Burgos, abril de 2022, Burgos.

Challenges in laser cleaning of cultural heritage stained glass Maingi, Evan Maina; Treil, Valérie; Alonso Abad, Mª Pilar; Angurel Lámban, Luis Alberto; Rahman, Md. Ashiqur; Chapoulie, Rémy; Dubernet, Stéphan; Schiavon, Nick; Fuente Leis, Germán F. de la Stained-glass windows play an important role in cultural heritage. Human and environmental factors have subjected these pieces to risks of damage. Mechanical and chemical-based cleaning methods have been used for their restoration and conservation. Additionally, short-pulse lasers have opened new opportunities for safe and controlled cleaning and restoration of these important materials. In this work, ultra-short pulsed lasers were used to clean an artificially applied coating from the surface of a contemporary colorless glass frequently used in the restoration of stained-glass windows. One of the objectives was to explore the applicability of using these types of lasers to safely clean historical stained-glass windows. It was observed that temperature rise and subsequent heat accumulation in the coating layer being removed was sufficient to generate significant thermal stresses on the underlying glass surface leading to damages even when the laser energies are lower than the damage thresholds. Some laser treatments that limit this heat accumulation were designed in this study. For laser systems operating at frequencies in the range of several hundreds of kHz, the option was to work in burst mode, limiting the number of pulses in each burst and selecting an adequate time lapse between two consecutive burst runs. A method to uniformly clean a given surface is proposed in this work. When lower frequencies are available, treatments using frequencies lower than 20 kHz are enough to safely clean the glass. When UV laser radiation is used, optical damage is also an important aspect to be considered. In this case, the cleaning protocol has to deal with both issues, to avoid heat accumulation and chemical damage.
