Este artículo pretende ser complemento y continuación de mis anteriores trabajos sobre la figura de Petrus Hispanus O. P., Auctor Summularum. Comienzo presentando algunos nuevos documentos relacionados con las cuestiones ya examinadas en mis artículos de 1997 y 2001. A continuación, me ocupo de las cuestiones aplazadas en el artículo de 2001: los problemas relativos a la figura de “Petrus Ferrandi” y su posible relación con el “auctor Summularum”, así como los argumentos de Tugwell contra la hipótesis de la posible identidad de estas dos figuras, examinados ahora desde la perspectiva del autor de la Legenda prima. Tras analizar testimonios procedentes de muy diversos ámbitos, afirmo, por una parte, que la hipótesis de la identidad entre “Petrus Ferrandi” y “Petrus Hispanus” podría ser correcta y, por otra parte, que no hay argumentos concluyentes que obliguen a afirmar con seguridad que el autor de la Legenda prima es Pedro Ferrando. Aunque los análisis no permiten por el momento determinar si es “Petrus Alfonsi” o “Petrus Ferrandi” el “auctor Summularum”, los testimonios recogidos y las conexiones establecidas contribuirán, sin duda, a orientar futuras investigaciones en torno a la figura de “Petrus Hispanus”.

The knowledge of thermodynamic high-pressure speed of sound in ionic liquids (ILs) is a crucial way either to study the nature of the molecular interactions, structure and packing effects or to determine other key thermodynamic properties of ILs essential for their applications in any chemical and industrial processes. Herein, we report the speed of sound as a function temperature at pressures up to 101 MPa in four ultrapure ILs: 1-propyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide, 1-butyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide, 1-pentyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide, and 1-hexyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide, taking into consideration their relaxation behavior. Additionally, to further improve the reliability of the speed of sound results, the density, isentropic compressibility, and isobaric heat capacity as a function of temperature and pressure are calculated using an acoustic method.

How do children experience participating in a choral performance? What matters most to them? How do they remember and talk about the event? The interview-based study demonstrates that children retain complex memories of such an event and can report on the experience in a differentiated manner, including their self-perception while singing, their social experience, and the various emotions associated with it. They evaluate the songs that were sung, and imbue the venue with meaning. Active participation in a choral performance enables children to share and reflect on music, providing them with a lasting, positively connoted memory of a musical experience. (DIPF/Orig.)
