Pere Compte, mestre major de l'obra de la Seu de Tortosa.

[cat] En aquest article es documenta Pere Compte com a mestre major de la Seu de Tortosa(1490), fet que es relaciona amb la promoció del protonotari apostòlic Joan Girona i es compara amb la direcció de les obres de Pere Moragues, que tingué lloc un segle abans. D'altra banda, es proposa la hipòtesi que sigui Pere Compte el responsable del disseny de la capella del Roser de l'esmentat edifici. També s'apunta la possibilitat que fos Antoni Queralt el mestre encarregat de dirigir el dia a dia de l'obra mentre Compte n'era absent i es posa de manifest la importancia que va poder tenir aquest mestre, especialment a Tortosa i a Lleida, a l'entorn del 1500. Finalment, es dóna notícia de la presencia d'altres mestres importants a la Tortosa del canvi de segles paral·lelament a la de Compte i Queralt al front de les obres de la Seu.

Characterizing major avalanche episodes in space and time in the twentieth and early twentyfirst centuries in the Catalan Pyrenees

With the aim of better understanding avalanche risk in the Catalan Pyrenees, the present work focuses on the analysis of major (or destructive) avalanches. For such purpose major avalanche cartography was made by an exhaustive photointerpretation of several flights, winter and summer field surveys and inquiries to local population. Major avalanche events were used to quantify the magnitude of the episodes during which they occurred, and a Major Avalanche Activity Magnitude Index (MAAMI) was developed. This index is based on the number of major avalanches registered and its estimated frequency in a given time period, hence it quantifies the magnitude of a major avalanche episode or winter. Furthermore, it permits a comparison of the magnitude between major avalanche episodes in a given mountain range, or between mountain ranges, and for a long enough period, it should allow analysis of temporal trends. Major episodes from winter 1995/96 to 2013/14 were reconstructed. Their magnitude, frequency and extent were also assessed. During the last 19 winters, the episodes of January 22-23 and February 6-8 in 1996 were those with highest MAAMI values,followed by January 30-31, 2003, January 29, 2006, and January 24-25, 2014. To analyze the whole twentieth century, a simplified MAAMI was defined in order to attain the same purpose with a less complete dataset. With less accuracy, the same parameters were obtained at winter time resolution throughout the twentieth century. Again, 1995/96 winter had the highest MAAMI value followed by 1971/72, 1974/75 and 1937/38 winter seasons. The analysis of the spatial extent of the different episodes allowed refining the demarcation of nivological regions, and improving our knowledge about the atmospheric patterns that cause major episodes and their climatic interpretation. In some cases, the importance of considering a major avalanche episode as the result of a previous preparatory period, followed by a triggering one was revealed.

Bauer-7-en-3beta-yl acetate: a major constituent of unusual samples of Brazilian propolis

The pentacyclic triterpenoid bauer-7-en-3beta-yl acetate was obtained from the chloroform extract of an unusual sample of propolis from southeast Brazil with the yield of 7%. The compound was identified by comparison of IR, MS and NMR analysis with published data.
