Stem canker and black scurf diseases of potatoes are caused by the basidiomycetous fungus Tanatephorus cucumeris (ana-morphic species complex Rhizoctonia solani). Tese diseases have worldwide distribution wherever potato is grown but their etiology varies depending on the predominance of distinct R. solani anastomosis groups (AGs) in a particular area. Within the species complex, several AGs have been associated with stem canker or black scurf diseases, including AG-1, AG-2-1, AG-2-2, AG-3, AG-4, AG-5 and AG-9. Tis article reports on the most comprehensive population-based study, providing evidence on the distribution of R. solani AGs in Colombian potato fields. A total of 433 isolates were sampled from the main potato cropping areas in Colombia from 2005 to 2009. Isolates were assigned to AGs by conventional PCR assays using specific primers for AG-3, sequencing of the ITS-rDNA and hyphal interactions. Most of the isolates evaluated were assigned to AG-3PT (88.45%), and a few to AG-2-1 (2.54%). Te remaining isolates were binucleate Rhizoctonia (AG-A, E, and I). Pathogenicity tests on the stems and roots of different plant species, including the potato, showed that AG-3PT affects the stems of solanaceous plants. In other plant species, damage was severe in the roots, but not the stems. AG-2-1 caused stem canker of Solanum tuberosum cv. Capiro and in R. raphanistrum and B. campestris subsp. Rapa plantlets and root rot in other plants. Te results of our study indicated that R. solani AG-3PT was the principal pathogen associated with potato stem canker and black scurf diseases of potatoes in Colombia.

Prevalence of Toxoplasma gondii infection in 510 free-range (FR) chickens (380 from 33 small farms, and 130 from a slaughter house for FR chickens) from Espirito Santo state, southeastern Brazil, was investigated. Antibodies to T. gondii were sought using commercial indirect haemagglutination (IHAT, Imuno-HAI Toxo (R), Wama Diagnostica, Sao Paulo, Brazil, cut-off 1:16) and the modified agglutination test (MAT, cut-off 1:25) tests. Attempts were made to isolate viable T. gondii from seropositive chickens by bioassay in mice. Pooled samples of brain, heart and quadriceps muscle of one thigh (total 40 g) from 64 chickens with IHAT titers of >= 1:16 were minced, digested in pepsin and bioassayed in mice. Antibodies to T. gondii were found in 40.4% (206/510) FR chickens by IHAT (titer >= 1:16) and 38.8% (198/510) by MAT (titer >= 1:25); concordance between IHAT and MAT was 81.6% (kappa index = 0.614). Viable T. gondii was isolated (designated TgCkBr234-281) from 48 of 64(75%) seropositive (IHAT titers >= 1:32) FR chickens. Most isolates of T. gondii were virulent for mice; 100% of mice inoculated with 44 of 48 isolates died of toxoplasmosis within 30 days post inoculation (p.i). An epidemiological investigation revealed that people living in rural areas have little knowledge about the parasite and about the risk of acquiring it from raw meat. Results indicated that the locally available IHAT was useful for screening of chicken sera for T. gondii antibodies. (C) 2012 Elsevier B.V. All rights reserved.

La tesi si occupa della «processione con Misteri» organizzata da Carlo Bascapè, preposito generale dei Barnabiti, a Milano, la notte del venerdì santo, a partire dal 1587. Di questo importante rito processionale sono giunte fino a noi diverse testimonianze documentarie, conservate presso l’Archivio Storico dei Barnabiti a Milano, che sono state il cuore di questa ricerca. La processione è una grande meditazione pubblica dove la musica svolge un ruolo molto importante. Il percorso che ho seguito è stato teso a rendere ragione delle motivazioni drammatiche e devozionali della processione, per poi approdare al significativo ruolo che la componente musicale svolgeva nel rito stesso. Nel primo capitolo ho rievocato la figura di Carlo Bascapè (1550-1615), inserendo la sua figura all’interno delle esperienze storiche nelle quali si è formato (la Milano di san Carlo Borromeo e l’Ordine dei Chierici regolari di San Paolo). Nel secondo capitolo ho scandagliato le radici devozionali alla base della processione (i concetti di devozione e orazione) e messo a fuoco il ruolo della musica nell’esperienza religiosa dei Barnabiti e, in particolar modo, di Carlo Bascapè. Il terzo capitolo si concentra sulle principali modalità di rappresentazione e meditazione della passione di Cristo. Nel quarto capitolo ho ricostruito, attraverso una lettura dei documenti, e con approfondimenti tratti dalla letteratura devozionale tardocinquecentesca sulla passione, i vari aspetti della processione e i suoi protagonisti (religiosi, nobili della città di Milano, musicisti), e, infine, ho messo in luce gli aspetti devozionali e drammaturgici. Nel quinto capitolo ho analizzato le musiche superstiti, pervenendo alla conclusione che ogni aspetto musicale era concepito tenendo ben presenti i due aspetti su cui era imperniata la processione: la rappresentazione della passione e l’immedesimazione dei fedeli. L’ultima parte della tesi consiste, infine, nella trascrizione dei documenti archivistici, nella loro parte testuale e musicale.

The euphotic depth (Zeu) is a key parameter in modelling primary production (PP) using satellite ocean colour. However, evaluations of satellite Zeu products are scarce. The objective of this paper is to investigate existing approaches and sensors to estimate Zeu from satellite and to evaluate how different Zeu products might affect the estimation of PP in the Southern Ocean (SO). Euphotic depth was derived from MODIS and SeaWiFS products of (i) surface chlorophyll-a (Zeu-Chla) and (ii) inherent optical properties (Zeu-IOP). They were compared with in situ measurements of Zeu from different regions of the SO. Both approaches and sensors are robust to retrieve Zeu, although the best results were obtained using the IOP approach and SeaWiFS data, with an average percentage of error (E) of 25.43% and mean absolute error (MAE) of 0.10 m (log scale). Nevertheless, differences in the spatial distribution of Zeu-Chla and Zeu-IOP for both sensors were found as large as 30% over specific regions. These differences were also observed in PP. On average, PP based on Zeu-Chla was 8% higher than PP based on Zeu-IOP, but it was up to 30% higher south of 60°S. Satellite phytoplankton absorption coefficients (aph) derived by the Quasi-Analytical Algorithm at different wavelengths were also validated and the results showed that MODIS aph are generally more robust than SeaWiFS. Thus, MODIS aph should be preferred in PP models based on aph in the SO. Further, we reinforce the importance of investigating the spatial differences between satellite products, which might not be detected by the validation with in situ measurements due to the insufficient amount and uneven distribution of the data.

El Comentario a las Sentencias, una obra de juventud del Aquinate, permite reconocer la presencia de Aristóteles en su pensamiento ya desde el comienzo de su producción filosófica. Uno de los temas donde claramente se nota su influencia es en la teoría del conocimiento, pues el joven dominico parece aceptar los aspectos centrales de la visión del Estagirita, aunque evidentemente las fórmulas y desarrollos no tienen aquí la precisión que se observa en escritos posteriores y en las que ciertamente uno encuentra un Santo Tomás más maduro. En el presente artículo quisiera desarrollar algunos elementos que surgen al analizar la importancia que se da en esta obra a lo sensible. En efecto, la frecuencia con la que el Aquinate recurre a Dionisio para completar e incluso corregir algunas afirmaciones de Aristóteles en este tema no puede menos que llamar la atención. A la necesidad de lo sensible se suma por ejemplo el hecho de concebir a la creación como símbolo de Dios o a lo material como un elemento mediador, dos temas de clara inspiración dionisiana. Como intento mostrar, aun reconociendo la presencia de Aristóteles, la posición de Santo Tomás en el tema de lo sensible y sobre todo en el papel que deben ocupar los sentidos no pueden ser comprendidos cabalmente sin reconocer en qué medida su pensamiento es tributario del Areopagita.

From the DSDP Legs 1, 11, 13, 17, 25, 27, 32, 36, 41, 43, 44, 50, and 62 the Lower Cretaceous foraminifers have been investigated for biostratigraphical, taxonomical, and palaeoecological purposes. An overview of the cored Lower Cretaceous sections of Leg 1-80 is given. In the Northern Atlantic Ocean characteristic foraminiferal faunas are missing from the Upper Tithonian to the Valanginian due to a marked regression which caused hiatuses. In areas without black shale conditions Valanginian to Barremian medium rich to poor microfaunas with Praedorothia ouachensis (Sigal) of the Praedorothia ouachensis Zone (Valanginian-Hauterivian). The Hauterivian-Aptian interval is characterized by zones of Gavelinella barrerniana, Gaudryina dividens, and Conorotalites aptiensis. During the Albian a world-wide fauna consisting of agglutinated and calcareous foraminifers of the Pseudoclavulina gaultina Zone is established in areas lacking the wide-spread black-shale conditions. The Upper Albian and the Cenomanian are represented by the Gavelinella eenomanica Zone. Some ornamented species of the nodosariids (Citharina, Lenticulina), Gavelinella, Conorotatites, Pleurostomella, Vatvulineria, and Osangularia are of some importance for the biostratigraphy of the Berriasian-Albian interval. The Berriasian to Albian zones introduced for the Tethys and the DSDP by Moullade (1984) could only be of some local importance due to the long stratigraphical range of the foraminiferal species used. In the Indian Ocean an exact stratigraphical age cannot be assigned to the few Neocomian foraminiferal faunas of a cooler sea water (Site 261). These faunas mainly contain primitive agglutinated foraminifers, because in most cases the calcareous tests are dissolved or redeposited. In the Pacific Ocean most of the Berriasian to Aptian microfaunas are of minor biostratigraphical and palaeoecological importance for reasons of poor core recoveries, contaminations or original foraminiferal poverty (black shales). Since the Albian there are somewhat higher-diverse faunas of calcareous and agglutinated foraminifers with index species of the Pseudoclavulina gaultina Zone. As a rule, the boundary Albian/Cenomanian is set by means of planktonic foraminifers because no other foraminifer has its first appearance datum during this interval, except Gavelinella cenornanica. During the Albian very uniform, world-wide foraminiferal faunas without a marked provincialism are obvious.

La provincia de Pernambuco es un importante escenario de la educación del Nordeste de Brasil. En lo que se refiere a la enseñanza de la Lengua Española, en la Enseñanza Fundamental y Media, se destaca la ciudad de Cabo de Santo Agostinho por ser pionera en la implementación del español en la Red Municipal. La discusión sobre la influencia hispánica en la ciudad empezó cuando algunos expertos, a través de estudios académicos, concluyeron que el navegador español Vicente Yáñez Pinzón arribó a tierras cabenses tresmeses antes que el portugués Pedro Álvares Cabral. Debido a eso, y a la importancia de Brasil en MERCOSUR, el Ayuntamiento de Cabo, a través de un proyecto de Ley, implementó el español como segunda lengua extranjera. Por esta razón, los docentes tuvieron formación continua ofrecida por La Facultad de Formación de Profesores de Olinda. Actualmente, la Coordinación de Lenguas de Cabo de Santo Agostinho realizó el I Encuentro Hispanoamérica de Cabo, el I Congreso Pernambucano de Profesores de Español y el I Simposio de Formación de Profesores de Español en Conmemoración a los veinte años de la Asociación de Profesores de Español de Pernambuco.
