Hydrography, current and microstructure measurements from R/V Håkon Mosby cruise HM2012610 to the Faroe Bank Channel overflow region

This data set includes the profiling measurements collected from ship during the cruise HM 2012610 onboard the Research Vessel Håkon Mosby. The cruise was conducted under the project entitled "Faroe Bank Channel Overflow: Dynamics and Mixing Research", with an objective to investigate the mixing and entrainment of the dense oceanic overflow from the Faroe Bank Channel. The profiling measurements delivered with this data set include conventional conductivity-temperature-depth (CTD) measurements, current profile measurements using a lowered acoustic Doppler Current Profiler (LADCP) system and ocean microstructure measurements using a vertical microstructure profiler (VMP2000). The observational programme was designed to measure turbulence and mixing in the overflow plume which, in addition to the shear-induced mixing at the plume-ambient interface, is hypothesized to be influenced by several processes including mesoscale eddies, secondary circulation and internal waves.

Il restauro della chiesa di San Francesco a San Giovanni in Persiceto: tecniche di rilevo ad alta definizione e sperimentazione di linguaggi diacritici per la reintegrazione delle superfici architettoniche

il lavoro si suddivide in una fase preliminare conoscitiva costituita da una ricerca storico-documentale sui principali eventi che hanno interessato San Giovanni in Persiceto e il complesso conventuale. per comprendere a pieno l'oggetto di studio sono stati studiati a fondo la vita e le opere dell'autore e le tendenze architettoniche del periodo storico in cui esercita. è stato eseguito un rilievo dettagliato impiegando tecniche ad alta definizione, come fotogrammetria e scansioni laser. per realizzare un progetto di restauro consapevole e rispettoso del monumento sono state condotte approfondite analisi tematiche e di degrado, in modo da acquisire una conoscenza diretta dell'edificio. per reintegrare l'unità d'immagine andata perduta, visto l'uso improprio che è stato fatto del bene, indispensabile per la comprensione dell'opera, è stata svolta un'attenta analisi della consistenza materica e una analogica con le opere dell'autore simili. gli interventi cercheranno di facilitare la lettura delle tracce presenti sul manufatto, e in maniera tutt'altro che invasiva verrà proposta la videoproiezione di quella che poteva essere l'immagine e la suggestione concepita dall'architetto. sono stati studiati restauri di casi analoghi e gli interventi della scuola di restauro nata a seguito delle devastazioni prodotte dalla guerra. per gli elementi ben conservati si attuerà un restauro conservativo. si restaura la pavimentazione, attraverso due diverse ipotesi che risolvono le possibili casistiche generate dalla rimozione delle superfetazioni. per valorizzare gli elementi architettonici si è proposto uno schema di sorgenti luminose diversificato in illuminazione generale d'ambiente ed un sistema di luci funzionale agli usi specifici.

James Fitzpiers Fitzgerald, Captain Thomas Lee, and the problem of ‘secret traitors’: conflicted loyalties during the Nine Years’ War, 1594-1603

Existing evidence pertaining to Ireland’s Nine Years’ War (1594–1603) strongly lends itself to the impression that the majority of Old English Palesmen, at least those of higher social status, chose to support the English crown during this conflict rather than their co-religionist Gaelic Irish countrymen. Loyalties, however, were anything but straightforward and could depend on any number of cultural values, social concerns, and economic incentives. Nevertheless, James Fitzpiers Fitzgerald, a ‘Bastard Geraldine’ who served as sheriff of Kildare, seemed to have been driven by a genuine sense of duty to the English crown and establishment. With the outbreak of hostilities in the 1590s, Fitzpiers proved to be a devout crown servitor, risking life and limb to confront the English queen’s Irish enemies. But, in late 1598 he suddenly, and somewhat inexplicably, threw his lot in with the Irish confederacy, defying the government he had once championed. During the ensuing investigation, the Dublin administration accumulated much damning evidence against Fitzpiers, including a patriotic plea from rebel leader Hugh O’Neill which urged Fitzpiers to defend his Irish homeland from the oppressions of English Protestant rule. Yet, at the very same time, a counter case was made by Fitzpiers’s controversial English friend, Captain Thomas Lee, which argued that Fitzpiers’s actions were more loyal than anyone could have imagined. Through an examination of Fitzpiers’s perplexing case, this paper will explore the complicated nature of allegiances in 1590s Ireland and how loyalties were not always what they seemed.

Table 1. Tree growth index and reconstructed precipitation series from 515 BC to AD 1993 based on the archaeological and living tree ring datasets from Dulan and Shenge, China

Annual precipitation for the last 2,500 years was reconstructed for northeastern Qinghai from living and archaeological juniper trees. A dominant feature of the precipitation of this area is a high degree of variability in mean rainfall at annual, decadal, and centennial scales, with many wet and dry periods that are corroborated by other paleoclimatic indicators. Reconstructed values of annual precipitation vary mostly from 100 to 300 mm and thus are no different from the modern instrumental record in Dulan. However, relatively dry years with below-average precipitation occurred more frequently in the past than in the present. Periods of relatively dry years occurred during 74-25 BC, AD 51-375, 426-500, 526-575, 626-700, 1100-1225, 1251-1325, 1451-1525, 1651-1750 and 1801-1825. Periods with a relatively wet climate occurred during AD 376-425, 576-625, 951-1050, 1351-1375, 1551-1600 and the present. This variability is probably related to latitudinal positions of winter frontal storms. Another key feature of precipitation in this area is an apparently direct relationship between interannual variability in rainfall with temperature, whereby increased warming in the future might lead to increased flooding and droughts. Such increased climatic variability might then impact human societies of the area, much as the climate has done for the past 2,500 years.

Grain-size, lithic grains, foraminifera-derived and dinocyst-derived data of sediment core MD99-2281

The last glacial period was punctuated by abrupt climatic events with extrema known as Heinrich and Dansgaard-Oeschger events. These millennial events have been the subject of many paleoreconstructions and model experiments in the past decades, but yet the hydrological processes involved remain elusive. In the present work, high-resolution analyses were conducted on the 12-42 ka BP section of core MD99-2281 retrieved southwest of the Faeroe Islands, and combined with analyses conducted in two previous studies (Zumaque et al., 2012; Caulle et al., 2013). Such a multiproxy approach, coupling micropaleontological, geochemical and sedimentological analyses, allows us to track surface, subsurface, and deep hydrological processes occurring during these rapid climatic changes. Records indicate that the coldest episodes of the studied period (Greenland stadials and Heinrich stadials) were characterized by a strong stratification of surface waters. This surface stratification seems to have played a key role in the dynamics of subsurface and deep-water masses. Indeed, periods of high surface stratification are marked by a coupling of subsurface and deep circulations which sharply weaken at the beginning of stadials, while surface conditions progressively deteriorate throughout these cold episodes; conversely, periods of decreasing surface stratification (Greenland interstadials) are characterized by a coupling of surface and deep hydrological processes, with progressively milder surface conditions and gradual intensification of the deep circulation, while the vigor of the subsurface northward Atlantic flow remains constantly high. Our results also reveal different and atypical hydrological signatures during Heinrich stadials (HSs): while HS1 and HS4 exhibit a "usual" scheme with reduced overturning circulation, a relatively active North Atlantic circulation seems to have prevailed during HS2, and HS3 seems to have experienced a re-intensification of this circulation during the middle of the event. Our findings thus bring valuable information to better understand hydrological processes occurring in a key area during the abrupt climatic shifts of the last glacial period.

Geochemistry of tephra from Lake Ohrid

Here we present a tephrostratigraphic record (core Co1202) recovered from the northeastern part of Lake Ohrid (Republics of Macedonia and Albania) reaching back to Marine Isotope Stage (MIS) 6. Overall ten horizons (OT0702-1 to OT0702-10) containing volcanic tephra have been recognised throughout the 14.94 m long sediment succession. Four tephra layers were visible at macroscopic inspection (OT0702-4, OT0702-6, OT0702-8 and OT0702-9), while the remaining six are cryptotephras (OT0702-1, OT0702-2, OT0702-3, OT0702-5, OT0702-7 and OT0702-10) identified from peaks in K, Zr and Sr intensities, magnetic susceptibility measurements, and washing and sieving of the sediments. Glass shards of tephra layers and cryptotephras were analysed with respect to their major element composition, and correlated to explosive eruptions of Italian volcanoes. The stratigraphy and the major element composition of tephra layers and cryptotephras allowed the correlation of OT0702-1 to AD 472 or AD 512 eruptions of Somma-Vesuvius, OT0702-2 to the FL eruption of Mount Etna, OT0702-3 to the Mercato from Somma-Vesuvius, OT0702-4 to SMP1-e/Y-3 eruption from the Campi Flegrei caldera, OT0702-5 to the Codola eruption (Somma-Vesuvius or Campi Flegrei), OT0702-6 to the Campanian Ignimbrite/Y-5 from the Campi Flegrei caldera, OT0702-7 to the Green Tuff/Y-6 eruption from Pantelleria Island, OT0702-8 to the X-5 eruption probably originating from the Campi Flegrei caldera, OT0702-9 to the X-6 eruption of generic Campanian origin, and OT0702-10 to the P-11 eruption from Pantelleria Island. The fairly well-known ages of these tephra layers and parent eruptions provide new data on the dispersal and deposition of these tephras and, furthermore, allow the establishment of a chronological framework for core Co1202 for a first interpretation of major sedimentological changes.

(Table 1) Chemical and isotopic composition of pore fluids in cores TGC-1 and TGC-6

The role of sediment diagenesis in the marine cycles of Li and B is poorly understood. Because Li and B are easily mobilized during burial and are consumed in authigenic clay mineral formation, their abundance in marine pore waters varies considerably. Exchange with the overlying ocean through diffusive fluxes should thus be common. Nevertheless, only a minor Li sink associated with the low-temperature alteration of volcanic ash has been observed. We describe a low-temperature diagenetic environment in the Black Sea dominated by the alteration of detrital plagioclase feldspars. Fluids expelled from the Odessa mud volcano in the Sorokin Trough originate from shallow (~100-400 m deep) sediments which are poor in volcanic materials but rich in anorthite. These fluids are depleted in Na+, K+, Li+, B, and 18O and enriched in Ca2+ and Sr2+, indicating that anorthite is dissolving and authigenic clays are forming. Using a simple chemical model, we calculate the pH and the partial pressure of CO2 (PCO2) in fluids associated with this alteration process. Our results show that the pH of these fluids is up to 1.5 pH units lower than in most deep marine sediments and that PCO2 levels are up to several hundred times higher than in the atmosphere. These conditions are similar to those which favor the weathering of silicate minerals in subaerial soil environments. We propose that in Black Sea sediments enhanced organic matter preservation favors CO2 production through methanogenesis and results in a low pore water pH, compared to most deep sea sediments. As a result, silicate mineral weathering, which is a sluggish process in most marine diagenetic environments, proceeds rapidly in Black Sea sediments. There is a potential for organic matter-rich continental shelf environments to host this type of diagenesis. Should such environments be widespread, this new Li and B sink could help balance the marine Li and Li isotope budgets but would imply an apparent imbalance in the B cycle.

Dos traducciones del español al inglés a finales del siglo XV

Al parecer, el primer libro traducido del español al inglés fue La Celestina, ca. 1525. Sin embargo, con anterioridad a esa fecha, hay constancia de que a finales del siglo XV se llevaron también a cabo traducciones de condición documental. De dos de ellas se da cuenta en este artículo: la traducción de una carta (previamente traducida del árabe al español) y la traducción de un documento comercial fechado el 29 de mayo de 1490.

Sexism and Imperialism in Mozart's Don Giovanni, Puccini's Madama Butterfly, and Blitzstein's Regina: A Performance Study

This dissertation project comprises three major operatic performances and an accompanying document; a performance study which surveys aspects of sexism and imperialism as represented in three operas written over the last three centuries by examining the implications of prejudice through research as well as through performances of the major roles found in the operas. Mr. Eversole performed the role of Sharpless in the 2014 Castleton Festival production of Madama Butterfly (music by Giacomo Puccini, libretto by Luigi Illica and Giuseppe Giacosa), conducted by Bradley Moore. In 2015, Mr. Eversole sang the title role in four performances of Mozart and Da Ponte’s Don Giovanni with the Maryland Opera Studio at the Clarice Smith Performing Arts Center, conducted by Craig Kier. Also as part of the Maryland Opera Studio 2015-16 season, Mr. Eversole appeared as Oscar Hubbard in four performances of Marc Blitzstein’s Regina, an adaptation of Lillian Hellman’s 1939 play, The Little Foxes. These performances were also conducted by Craig Kier. The accompanying research document discusses significant issues of cultural, geographical, and sexual hegemony as they relate to each opera. It examines the plots and characters of the operas from a postcolonial and feminist perspective, and takes a moral stance against imperialism, sexism, domestic abuse, and in general, the exploitation of women and of the colonized by the socially privileged and powerful. Recordings of all three operas can be accessed at the University of Maryland Hornbake Library. They are: Giacomo Puccini’s Madama Butterfly (the role of Sharpless) July 20, 2014, Castleton Festival production, Bradley Moore, Conductor Castleton, Virginia Wolfgang Amadeus Mozart’s Don Giovanni (title role) November 22nd, 2015, Maryland Opera Studio, Craig Kier, Conductor Clarice Smith Performing Arts Center, UMD Marc Blitzstein’s Regina, (Oscar Hubbard) April 8th, 8016, Maryland Opera Studio, Craig Kier, Conductor Clarice Smith Performing Arts Center, UMD

Sistemas normativos. Introducción a la metodología de las ciencias jurídicas

En esta nueva edición se ha modificado el título y se han eliminado algunos errores tipográficos, entre otros. Pero el hecho de que esta obra fuera primero publicada en su versión inglesa (Norrnative Systems, Wien - New York, Springer Verlag, 1971) ha provocado algunas confusiones que conviene aclarar. El libro fue escrito en castellano y el título originario era Sistemas normativos, que nos fue sugerido por Mario Bunge, editor de la serie "Library of Exact Philosophy" en la que apareció la versión inglesa. La traducción fue llevada a cabo por los autores, con enorme ayuda de Mrs. Joan Mackie, quien revisó todo el texto. Esa traducción apareció primero y la versión original (castellana) fue publicada cuatro años más tarde por Editorial Astrea con un título cambiado: Introducción a la metodología de las ciencias jurídicas y sociales. Este cambio en la versión castellana fue sugerido por Astrea y aceptado a regañadientes por los autores. Además, como en la traducción inglesa resolvimos suprimir algunos párrafos por parecernos demasiado locales (§ 5 del cap. 11) y en la versión castellana fue añadido el § 7 del cap. IV, ambas ediciones no resultaron idénticas. Es así como mucha gente pensó que la versión inglesa era la original, que luego fue traducida al castellano. El título con que la obra aparece ahora fue tomado de la excelente traducción italiana de Pierluigi Chiassoni y Giovanni Battista Ratti (Torino, G. Giappichelli Editare, 2005), quienes incluyeron los párrafos suprimidos en la versión inglesa, de modo que la versión italiana es prácticamente idéntica al texto original, que con esta edición aparece ahora en Astrea, también con su título original.
