In memoriam Antonio Prevosti (1919-2011), a pioneer of genetics of natural populations

Prof. Dr. Antonio Prevosti was born on the 15th of February, 1919, at Barcelona where he grew up and lived with his wife Maria Monclús and his family until his death. Between the years 1939 and 1942 he registered at the University of Barcelona and finished his studies there with the"University Degree in Natural Science" obtaining the extraordinary award of his promotion. Immediately afterwards he started his research about the growth rate of Barcelona school children from two very different social groups at the Anthropology Laboratory of the University of Barcelona. The obtained results were published in his Doctoral Thesis (1948). Further investigations on quantitative traits in human populations improved his knowledge of statistical analyses and provided the basis for a scholarship from the Italian Ministry of Foreign Affairs to work at the Institute of Statistical and Demographical Sciences in Rome directed by Prof. C. Gini.

El Jardín de Falerina, Francisco de Rojas Zorrilla, Antonio Coello Ochoa y Pedro Calderón de la Barca. Edición, introducción y notas de Felipe B. Pedraza Jiménez y Rafael González Cañal, (Barcelona: Octaedro, 2010)

Parece mentira que una pieza teatral firmada por Calderón de la Barca haya tardado más de tres cientos años en aparecer impresa y que sea ahora,en el 2010, cuando lo haga por primera vez. ¿A qué se debe esta falta de interés por la obra?La respuestanos la ofrecen Felipe B. Pedza Jiménez y Rafael González Cañal en el capítulo que abre el estudio preliminar de su edicion tulado«Razones de una sin razón»

Antonio Agustín, Bologna e l’antiquaria del Cinquecento

One of the founders of numismatics in Modern Age was the archbishop of Tarragona and renowned jurist Antonio Agustín. He was educated during the mid-sixteenth century mainly in Italy, particularly in Bologna and Padua. His role in the development of antiquarian studies – and interest in collecting – ran parallel to the development of numismatics in the Cinquecento. His interest in realia , i.e., the materials and documents perceived as primary evidence of history understood in a global sense, make him a pioneer in setting the trends and methodologies which would be later employed by Bernard de Montfaucon. The period Antonio Agustín spent in Bologna, at the Reale Collegio di Spagna, between 1539 and 1544, afforded him the opportunity to enter a very cultivated circle where the admiration and study of the Antique was well established since the mid-fifteenth century. The cultural effervescence taking place in Bologna was encouraged by the court of Giovanni II Bentivoglio and the University alike. Artists also contributed to the development of antiquarian knowledge, and the painter Amico Aspertini (ca. 1475-1552) exemplifies this. It is clear that Antonio Agustín certainly benefited from the scholarly environment in Bologna during the first half of the Cinquecento, which had been firmly anchored since the fertile Quattrocento. Although the documentary evidence is scarce, and it is difficult to pinpoint the details, it is undeniable that Antonio Agustín was heavily influenced by his Bolognese experience.

Spermiogenesis and spermatozoon ultrastructure of the dilepidid cestode Molluscotaenia crassiscolex (von Linstow, 1890), an intestinal parasite of the common shrew Sorex araneus

Spermiogenesis in Molluscotaenia crassiscolex begins with the formation of a differentiation zone containing two centrioles. One of the centrioles develops a flagellum directly into the cytoplasmic extension. The nucleus elongates and later migrates along the spermatid body. During advanced stages of spermiogenesis, a periaxonemal sheath appears in the spermatid. Spermiogenesis finishes with the appearance of a single helicoidal crested body at the base of the spermatid and, finally, the narrowing of the ring of arched membranes causes the detachment of the fully formed spermatozoon. The mature spermatozoon of M. crassiscolex exhibits a partially detached crested body in the anterior region of the spermatozoon, one axoneme, twisted cortical microtubules, a periaxonemal sheath, and a spiralled nucleus. The anterior spermatozoon extremity is characterized by the presence of an electron-dense apical cone and a single spiralled crested body, which is attached to the sperm cell in the anterior and posterior areas of region I, whereas in the middle area it is partially detached from the cell. This crested body is described for the first time in cestodes. The posterior extremity of the male gamete exhibits only the disorganizing axoneme. Results are discussed and compared particularly with the available ultrastructural data on dilepidids sensu lato.

A Pragmatic Intellectual: Dutch Fabians, Boekman, and Cultural Policy in the Netherlands, 1890-1940

Around 1900, the notion of community art (gemeenschapskunst) served to crystallize Dutch social democratic thinking about the role of the arts in society. Drawing on the pragmatism of leading social democrats like Wibaut, and drawing on his formal education in economics and statistics, the self‐made social democrat Emanuel Boekman redressed the utopian meaning of community art to signify the dissemination of "good" culture over all layers of society in his influential 1939 dissertation on the relation of the state to the arts. Being about facts rather than opinions, Boekman set the boundaries of his work to exclude a substantial discussion of the meaning of "good" culture. On the one hand, this pragmatism helped Boekman to gain support for government intervention for the arts over most of the political spectrum. On the other hand, Boekman thus pre‐empted discussions about the tension between "quality" and "accessibility" of the arts that haunts cultural policy in the Netherlands to this day.

"Vedo il male e non lo posso schivare" : le rime di Antonio Brocardo tra classicismi e polemiche

Antonio Brocardo è ricordato per essere entrato in polemica con Pietro Bembo, suscitando clamore e indignazione. Le fonti antiche sulla vita del Bembo lo descrivono come un folle intento a distruggere qualcosa che non riusciva bene a comprendere Vitaliani lo definisce, nel titolo della sua monografia del 1902 (l'unica fino ad ora dedicata al poeta), «vittima del bembismo», probabilmente risentendo dei pesanti giudizi sul cardinale già presenti in Leopardi e poi nel De Sanctis. Eppure, già a partire da Croce, si cerca di ricostruire in maniera meno pregiudizievole la figura del poeta veneziano, considerando più da vicino i testi pervenuti. Ci si trova, però, di fronte ad uno scarto imponente: la tradizione lo vuole opposto al bembismo, mentre la lirica brocardiana non sembra per molti aspetti differenziarsi così platealmente dal canone bembesco, a giudizio di molte storie letterarie. Questa nuova edizione mira: a ricostruire scrupolosamente la biografia del poeta, l'ambiente frequentato ed i rapporti con altri poeti/intellettuali del suo tempo; a fare finalmente chiarezza sulle polemiche che videro il giovane veneziano come protagonista, a partire dalle fonti contemporanee (correggendo quanto riportato dalle biografìe del Bembo o dalle storie letterarie); a fornire un adeguato commento alle sue rime, dopo aver ristabilito un sicuro testo critico; a fare maggior chiarezza sul rapporto tra Brocardo ed il furbesco letterario; a collocare il poeta in una ben determinata fase del petrarchismo.

Fixação de nitrogênio: estrutura, função e modelagem bioinorgânica das nitrogenases

Biological nitrogen fixation, catalyzed by nitrogenases, contributes about half of the nitrogen needed to global agriculture. For forty years synthetic chemists and theoreticians have tried to understand and model the structure and function of this important metalloenzyme. Ten years after the first report on the crystal structure of the MoFe protein, scientists still have not been able to synthesize a chemical equivalent of the FeMo cofactor nor the structure knowledge revealed the key to its catalytic activity. This paper with 104 references presents a review of the most relevant advances in chemical nitrogen fixation and their relation with the nitrogenases.

De Francisco a Marco Antonio Aldana pasando por Gaspar

It is traditionally considered that the «Aldana», whom Gaspar Gil Polo praises at the end of his «Canto de Turia» (1564), was Francisco de Aldana, the «divino». It is nonetheless more probable that it was in fact rather the Valencian poet, Marco Antonio Aldana, almost forgotten today, but very much in the public eye within the cultivated circles of the end of the sixteenth century Valencia

O químico e naturalista luso-brasileiro Alexandre Antonio Vandelli

Alexandre Vandelli was the heir of two illustrious scientific traditions in the Luso-Brazilian world of the late eighteenth and early nineteenth centuries, that of his father, the celebrated Italian-Portuguese naturalist and chemist Domingos (Domenico) Vandelli, and that of his father-in-law, that protean figure in several scientific specialties as well as in politics, José Bonifácio de Andrada e Silva, who in later life was of paramount importance in the process of Brazilian independence from Portugal. The younger Vandelli followed their footsteps but soon engaged in a multiple career, at first in Portugal and later in Brazil, of which little is known and is here presented for the first time.
