Max Reger (1873-1916) i Karl Straube (1873-1950) : tradició i evolució històrica de l'orgue a Alemanya

El present treball es centra en la relaci ó entre Max Reger i Karl Straube i les seves conseqüències interpretatives, tot vinculant-la amb els corrents socials, est ètics i musicals de tot el segle XIX i principis del segle XX. S'avalua el rellevament de la col ·laboració entre compositor i organista, recorrent a expressions i reflexions dels propis protagonistes i de persones properes a ambd ós. La metodologia es basa en l'an àlisi i la comparaci ó de materials editats i aut ògrafs, manuscrits, cartes, i enregistraments amb la finalitat d'aclarir una relaci ó humana, professional i musical de gran envergadura per la hist òria de l'orgue a Alemanya.

Magnetic moments of the Lambda(1405) and Lambda(1670) resonances

By using techniques of unitarized chiral perturbation theory, where the Lamda(1405) and Lamda(1670) resonances are dynamically generated, we evaluate the magnetic moments of these resonances and their transition magnetic moment. The results obtained here differ appreciably from those obtained with existing quark models. The width for the Lamda(1670)->Lamda(1405)gamma transition is also evaluated, leading to a branching ratio of the order of 210-6.

Greek misogynist tradition in Andreas Capellanus's De amore

The title of this brief article quite clearly illustrates its aims and evident limitations. In principle, a search for a Greek basis of the misogynist content of Andreas Capellanus's De amore is likely to lead researchers to focus on analysis of the sources -Greek sources, of course. However, there is no doubt that Ovid, the most frequently quoted ancient author, in this case the structural source, above all his Ars Amatoria, Remedia Amoris and Heroides, which is quite logical in light of the remarkable presence and influence of Ovid's works throughout that time. There was also a good knowledge of the works of Cicero, Virgil, Horace and Juvenal. However, other classical authors, even the Greeks -those who were known then-, were undoubtedly read in the schools, but the knowledge of their works was certainly superficial. Furthermore, given the scholastic method followed in De amore, it would be absurd not to consider the use of many quotations that appeared in the Compendia and in handbooks of religious instruction.

Legislación sanitaria marítima en Catalunya: 1717-1752

Aquesta publicació la formen les transcripcions d'unes disposicions legals establertes entre 1717 i 1752 pels guanyadors de la guerra de Successió (1702-1714). Es tracta doncs de legislació sanitària dictada específicament per al litoral marítim català. També trobem un estudi previ de l'autor sobre la situació política i social de la Catalunya i especialment de Barcelona després de la derrota de mans de les tropes de Felip V.

The first SEPServer event catalogue 68-MeV solar proton events observed at 1 AU in 1996-2010

SEPServer is a three-year collaborative project funded by the seventh framework programme (FP7-SPACE) of the European Union. The objective of the project is to provide access to state-of-the-art observations and analysis tools for the scientific community on solar energetic particle (SEP) events and related electromagnetic (EM) emissions. The project will eventually lead to better understanding of the particle acceleration and transport processes at the Sun and in the inner heliosphere. These processes lead to SEP events that form one of the key elements of space weather. In this paper we present the first results from the systematic analysis work performed on the following datasets: SOHO/ERNE, SOHO/EPHIN, ACE/EPAM, Wind/WAVES and GOES X-rays. A catalogue of SEP events at 1 AU, with complete coverage over solar cycle 23, based on high-energy (~68-MeV) protons from SOHO/ERNE and electron recordings of the events by SOHO/EPHIN and ACE/EPAM are presented. A total of 115 energetic particle events have been identified and analysed using velocity dispersion analysis (VDA) for protons and time-shifting analysis (TSA) for electrons and protons in order to infer the SEP release times at the Sun. EM observations during the times of the SEP event onset have been gathered and compared to the release time estimates of particles. Data from those events that occurred during the European day-time, i.e., those that also have observations from ground-based observatories included in SEPServer, are listed and a preliminary analysis of their associations is presented. We find that VDA results for protons can be a useful tool for the analysis of proton release times, but if the derived proton path length is out of a range of 1 AU < s[3 AU, the result of the analysis may be compromised, as indicated by the anti-correlation of the derived path length and release time delay from the asso ciated X-ray flare. The average path length derived from VDA is about 1.9 times the nominal length of the spiral magnetic field line. This implies that the path length of first-arriving MeV to deka-MeV protons is affected by interplanetary scattering. TSA of near-relativistic electrons results in a release time that shows significant scatter with respect to the EM emissions but with a trend of being delayed more with increasing distance between the flare and the nominal footpoint of the Earth-connected field line.
