Attosecond all-optical control and visualization of quantum interference between degenerate magnetic states by circularly polarized pulses
Authors: Shu Chuan-Cun , Guo Yu , Yuan Kai-Jun , Dong Daoyi , Bandrauk André D.
Published: January 2020

Controlling coherence and interference of quantum states is one of the central goals in quantum science. Different from energetically discrete quantum states, however, it remains a demanding task to visualize coherent properties of degenerate states (e.g., magnetic sublevels). It becomes further inaccessible in the absence of an external perturbation (e.g., Zeeman effect). Here, we present a theoretical analysis of all-optical control of degenerate magnetic states in the molecular hydrogen ion,

, by using two time-delayed co- and counterrotating circularly polarized attosecond extreme-ultraviolet (XUV) pulses. We perform accurate simulations to examine this model by solving the three-dimensional time-dependent Schrödinger equation. A counterintuitive phenomenon of quantum interference between degenerate magnetic sublevels appears in the time-dependent electronic probability density, which is observable by using x-ray-induced transient angular and energy-resolved photoelectron spectra. This work provides an insight into quantum interference of electron dynamics inside molecules at the quantum degeneracy level.
Photo-induced effects in Ge-As-Se films in various states
Authors: Zhang Zheng , Xu Siwei , Chen Yimin , Shen Xiang , Wang Rongping
Published: January 2020

Amorphous Ge-As-Se thin films have been prepared by the magnetron sputtering deposition technique, and the photo-induced effects (PIEs) in the different states have been investigated. It was found that, for the as-deposited films, Ge5 exhibits photodarkening (PD) while Ge15 and Ge25 undergo photobleaching (PB), and the degree of PB in Ge25 is larger than that in Ge15. On the other hand, all the annealing films exhibit PD, and the degree of PD decreases from Ge5 to Ge25. In all cases, PD is reversible while PB is irreversible. The Ge/As ratio or the lone pair electrons in Se atoms that were suggested for PIEs in the chalcogenide films cannot account for the present results in the GeAsSe films. Nevertheless, Ge15 exhibits minimum PIEs during a continuous illumination process that could be the best option for waveguide fabrication.
Optimizing an interleaved p-n junction to reduce energy dissipation in silicon slow-light modulators
Authors: Passoni Marco , Gerace Dario , O’Faolain Liam , Andreani Lucio Claudio
Published: January 2020

Reducing power dissipation in electro-optic modulators is a key step for widespread application of silicon photonics to optical communication. In this work, we design Mach–Zehnder modulators in the silicon-on-insulator platform, which make use of slow light in a waveguide grating and of a reverse-biased p-n junction with interleaved contacts along the waveguide axis. After optimizing the junction parameters, we discuss the full simulation of the modulator in order to find a proper trade-off among various figures of merit, such as modulation efficiency, insertion loss, cutoff frequency, optical modulation amplitude, and dissipated energy per bit. Comparison with conventional structures (with lateral p-n junction and/or in rib waveguides without slow light) highlights the importance of combining slow light with the interleaved p-n junction, thanks to the increased overlap between the travelling optical wave and the depletion regions. As a surprising result, the modulator performance is improved over an optical bandwidth that is much wider than the slow-light bandwidth.
Optical beam steering by using tunable, narrow-linewidth butt-coupled hybrid lasers in a silicon nitride photonics platform
Authors: Zhu Yeyu , Zeng Siwei , Zhu Lin
Published: January 2020

Chip-scale, tunable narrow-linewidth hybrid integrated diode lasers based on quantum-dot RSOAs at 1.3 μm are demonstrated through butt-coupling to a silicon nitride photonic integrated circuit. The hybrid laser linewidth is around 85 kHz, and the tuning range is around 47 nm. Then, a fully integrated beam steerer is demonstrated by combining the tunable diode laser with a waveguide surface grating. Our system can provide beam steering of 4.1° in one direction by tuning the wavelength of the hybrid laser. Besides, a wavelength-tunable triple-band hybrid laser system working at

Come “statue di bronzo”
Authors: Pentassuglio Francesca
Published: January 2020

Obiettivo del presente contributo è un esame dei riferimenti al tema del silenzio in alcuni “luoghi” della letteratura socratica. Più particolarmente, l’analisi si concentra sull’importanza riconosciuta alla virtù del σιωπᾶν in due specifici ambiti: 1) l’educazione dei giovani e 2) lo scambio dialogico. Il primo aspetto è indagato soprattutto a partire dal Milziade di Eschine di Sfetto, che presenta positivamente la capacità di tacere nei giovani (Stob. 2.31, 23; Plu. De recta rat. aud. 4 p. 39b-c) e che permette di istituire, a questo riguardo, alcuni paralleli con opere non socratiche (in particolare X. Lac. 3.5 e Isoc. Bus. 28-29). Il secondo aspetto, non privo di connessioni con il primo, è invece approfondito soprattutto a partire da un riferimento al ruolo del silenzio nel Protagora platonico (329b), che consente di indagarne la funzione più specificamente anti-sofistica.
Probing Into Space-Time View
Authors: Hu Chang-Wei
Published: January 2020

Space-time view is the cornerstone of physics, which can be divided into two categories. One is the absolute space-time view, it is a description of pure and real space-time. Because there is no a space with nothing, the absolute space-time view will deviate from the actual measured value quantitatively. The second is the view of material space-time, which is the result of observing the world through some medium. The principles of cosmology play an important role in the view of material space-time. The relativistic space-time view is a material space-time view, its material basis is the physical vacuum, that is, ether. The invariability principle of light velocity is intrinsically related to the principle of cosmology.

La cooperación académica en educación superior entre México y España 1977-2017. Una política migratoria y contexto de acogida diferenciado
Authors: Trejo Peña Alma Paola
Published: January 2020

La movilidad académica y estudiantil ocurre gracias a la cooperación académica entre Estados. Desde 1977, con el restablecimiento de las relaciones entre México y España, la cooperación académica de nivel superior se ha incrementado y reglamentado a través de instrumentos normativos que intensifican los intercambios tanto de académicos como de estudiantes. Ambos países forman parte de redes de colaboración que fomentan la movilidad académica y estudiantil en Iberoamérica. Además, la adquisición de Recursos Humanos Altamente Calificados (RHAC) resulta fundamental para que estos países desarrollen innovaciones tecnológicas y avances científicos. En este artículo buscamos determinar si la política migratoria y de cooperación académica para RHAC influye en la retención de talentos. Se analizan la legislación de extranjería de gestión de RHAC e instrumentos normativos entre México y España. Entre los principales resultados destacan que la cooperación académica se ha estrechado y, a diferencia del caso español, el contexto de acogida en México es más favorable, pues facilita la permanencia de los académicos españoles en el país.

Der codierte Christus Figuration als Bild-Text-Dynamik im De laudibus sanctae crucis des Hrabanus Maurus
Authors: Schulz Matthias
Published: January 2020

Among the early medieval illuminated manuscripts of the ninth century, the De laudibus sanctae crucis (Cod. Reg. Lat 124) by Hrabanus Maurus offers one of the most complex interplays of image-text relationships based on carmina figurata. It unfolds different levels and strategies of figuration. The specific aspects and qualities of its iconic practice can be described as a kind of coding. The coded subject and leitmotif of the cycle, which affects and gives structure to all other miniatures, is the central figure of Christus triumphans. The essay focuses on the detailed description and analysis of this symbiotic dynamic of a figural impulse that combines seeing, reading, and imagination into a meta-concept of figuration.
Giulio Mancini e la nascita della connoisseurship
Authors: Pierguidi Stefano
Published: January 2020

The role of Giulio Mancini as the father of connoisseurship has been recently questioned on the grounds that Mancini never aimed to discuss the attributions of contemporary works of art. Generally the birth of modern connoisseurship, with figures such as the Richardson brothers, has been linked to the growing art market of the 18th century, and the most important 17th-century forerunners, such as Marco Boschini, acted as dealers as well: all these connoisseurs dealt with the attributions of paintings of the previous centuries. This paper explores the roots of connoisseurship in the topography work of Mancini, author of the first modern artistic guide to Rome. Mancini, studying the early Renaissance frescoes in Rome (Jacopo Ripanda, Pastura, Pinturicchio, Baldassarre Peruzzi), discussed Vasari’s biographies and suggested new attributions with a modern approach that clearly anticipates the method of later connoisseurs.
MapTap and Cornelia Slow Digital Art History and Formal Art Historical Social Network Research
Authors: Brosens Koenraad , Alen Klara , Slegten Astrid , Truyen Fred
Published: January 2020

The essay introduces MapTap, a research project that zooms in on the ever-changing social networks underpinning Flemish tapestry (1620 – 1720). MapTap develops the young and still slightly amorphous field of Formal Art Historical Social Network Research (FAHSNR) and is fueled by Cornelia, a custom-made database. Cornelia’s unique data model allows researchers to organize attribution and relational data from a wide array of sources in such a way that the complex multiplex and multimode networks emerging from the data can be transformed into partial unimode networks that enable proper FAHSNR. A case study revealing the key roles played by women in the tapestry landscape shows how this kind of slow digital art history can further our understanding of early modern creative communities and industries.
Portraiture under Epoché: Matisse According to Husserl
Authors: Zeidler Sebastian
Published: January 2020

The article considers a range of issues in Henri Matisse’s art from around 1906 through the lens of Edmund Husserl’s theory of the image: the treatment of light and color in Matisse’s Young Sailor II, his combination of image and sign in the portrait of his daughter Marguerite, and the interaction between marks and sheet in his drawings. In Matisse’s art and Husserl’s phenomenology, just what was a portrait; and what, more broadly, was the relation between a modern self and his world? The answers to these questions suggest why Husserl has become such a popular reference point for Bildwissenschaft. A century ago, Husserl and Matisse did what contemporary image culture is now doing as a matter of course. In putting their world under epoché, they experienced it by expelling themselves from it.
Gold, Licht und das Potenzial des Mosaiks
Authors: Schellewald Barbara
Published: January 2020

The article focuses on the complex interaction between gold and light in the very specific medium of mosaic in Late Antiquity and Byzantium. Studying the metaphoric qualities of light/gold and its qualitative distinctions in early Christian and Byzantine sources leads us to an understanding of the complex function of gold or golden tesserae in script and images. As gold is understood as light, mosaic seems to be a more or less perfect medium as it is not stable, but dependent on the changing light. The gold ground is transformed in every moment by light. Mosaic can thus be understood as the medium with the greatest capacity to bridge – virtually – the gap between the visible and the invisible divine light.
“Framing and Fashioning of Images”: The Pictorial Invention of the Art Lover in Daniel Mytens’s Portrait of Thomas Howard, Earl of Arundel (ca 1618)
Authors: Volmert Miriam
Published: January 2020

The article examines Daniel Mytens’s portrait of Thomas Howard, Earl of Arundel, and the pendant portrait of his wife, Aletheia Howard (ca 1618), in relation to early modern rhetorical concepts in portrait painting and art theory. Particular focus is placed on the pictorial meaning of the depicted sculpture gallery in Lord Arundel’s portrait in its relation to the sitter. The author argues that the composition subtly transforms certain patterns of a long-standing pictorial code in portrait painting, which can be identified as a type of “picture within a picture.” Already established in the Italian portrait tradition, an integrated little picture or window view next to the sitter was a widespread formula in seventeenth-century Dutch and British portraiture, in order to praise a sitter’s moral and political virtues. Mytens reinterprets this portrait type, in this way inventing a pictorial mode of highlighting the particular virtues of the art lover: his portrait, through its adaptation of the picture-within-a-picture formula, praises the earl’s noble act of collecting antiquities while at the same time strongly emphasizing his intellectual strength.
Neue Einbände für alte Handschriften
Authors: Wittekind Susanne
Published: January 2020

A book cover encloses the manuscript inside. If it is elaborate, it distinguishes the manuscript as a precious and valuable object (as a frame does for a painting), all the more so when an old manuscript is clothed in a new and costly cover. In conjunction with added texts and other traces of use, one can grasp from this ‘reframing’ a shift of a text’s meaning. This is especially true of Gospel Books, which were handled as symbols of God in liturgical contexts. From the High Middle Ages on, treasure inventories and oath formulae were added to Gospel Books. They indicate the importance of an old Gospel Book for the religious community as a material proof of the age and rank of their church. Gospel Book covers from the High and Late Middle Ages demonstrate this by using spolia, old-fashioned forms and material, or invoking venerated founders. Often shaped as pendants, they seem to be arranged for display.
Vom liturgischen Textil zum Werbebanner? Zwei byzantinische Goldstickereien im Dom zu Halberstadt
Authors: Strohmaier Patricia
Published: January 2020

Two church banners made from a garment of late-fourteenth-century Italian lampas display two late-twelfth-century purple veils embroidered with gold. Bishop Konrad of Krosigk, having acquired a treasure of relics, textiles, and liturgical objects during the Fourth Crusade, donated these to his cathedral. The article focuses on how the two veils, which originally had veiled the chalice and the paten in the Byzantine mass, were reused and reframed. There is evidence that at first they were displayed upon or close to the altar, representing the cathedral’s new wealth by their costly appearance and Greek inscriptions evoking the splendor of Byzantine textile production. When sewn on church banners in the fifteenth century, they assumed the role of an advertisement for the Byzantine treasure, an attempt to reaffirm the marginalized cathedral’s prestige.
›Reframing‹ mittelalterlicher Skulpturen: Verschönerung, Umnutzung, Neuinterpretation?
Authors: Bergmann Ulrike
Published: January 2020

Medieval wooden sculptures were in most cases reframed several times during their history. Sculptures have thus been repainted or reused in different contexts. The reasons for these reframings have been different, for example change of taste, use, or place, or repair of damage. Sculptures of the Virgin Mary were especially subject to these later changes, because they were the focus of veneration and thus were exposed to touching hands, burning candles, and incense. In addition, the image of the Virgin was often exposed to fashionable new stylings. Medieval reframings can only be traced by very close examination of the object and are difficult to link with a specific historical context. Therefore, this study concentrates on some examples of medieval sculptures in Cologne, which have been the subjects of intense studies by restorers and art historians.
Neupräsentationen und Umdeutungen des Heiligen Kreuzes von Polling vom 13. bis zum 18. Jahrhundert
Authors: Seeberg Stefanie
Published: January 2020

The center of the baroque altarpiece of the Augustinian Monastery of Polling in South Germany forms the so-called Holy Cross. Its current presentation, dated from 1763, is the last of a sequence of four well-documented presentations of a Romanesque wooden cross since 1230. This cross is an excellent example for analyzing and comparing several methods of re-presenting a historic art object as well as for understanding the motivation for such re-presentations, which are grounded on changes of the spiritual function of the object. In its first reframing, the cross received a covering of gilded parchment and a painting of the crucifix on this ground coat. In a fundamental publication from 1994, this covering was compared with a reliquary holding the old venerated wooden cross. However, looking at the context of medieval instructions for painters and the material evidence of extant contemporary paintings, this interpretation becomes questionable: the covering with parchment was a common and technically motivated procedure rather than a spiritually motivated one.
The Lost Gothic Statue of St. Wenceslas at the Old Town Bridge Tower
Authors: Gajdošová Jana
Published: January 2020

This article suggests that a Gothic statue of St. Wenceslas once stood in front of Prague’s Old Town Bridge Tower in a location where a miracle associated with the translation of the saint’s body occurred. Consequently, the statue complemented the east façade’s sculptural program but was also set away from it in order to signal the saint’s significance here. This location in turn encouraged the viewers below to interact with the statue in a very intimate way, and also to make a link between this canonized Bohemian ruler and Emperor Charles IV. The emperor’s own statue on the façade, fashioned with the symbols of St. Wenceslas, leaned out of its architectural niche in order to look down at the saint-king and to emphasize the link between the two rulers.
Silver and Sanctified Bookkeeping: St. Eligius and the Smelting of Sin in the Wittenberg Heiligtum
Authors: Huber Stephanie Lebas
Published: January 2020

This article examines Lucas Cranach’s renderings of two non-extant silver gilt reliquaries made in the likeness of St. Eligius from the electoral Heiligtu. in Wittenberg. The significance of Eligius’s dual roles as both a metalworker for the Merovingian kings and as the bishop of Noyon bestowed the prince-electors in Wittenberg, most notably Frederick the Wise, with the ability to cleanse their treasury of all sin associated with indulgences. To explain the prominent place given to Eligius’s image in the collection, the article investigates his connection to French royalty, Holy Roman Emperor Charles IV’s valorization of his cult, the meaning attributed to his image in vernacular legends, and the evolving administrative role of bishops across the Middle Ages.
Verkörperung – Entkörperung bei Rembrandt
Authors: Koos Marianne
Published: January 2020

This article analyzes the painterly formation of pictorial subjects of embodiment and disembodiment since the early modern period. Starting with Gerhard Richter, Quattrocento painters, and Titian, it focuses on Rembrandt and his late group portrait The Anatomy Lesson of Dr. Deijman (1656). The subject of this picture is a dissection of a man’s brain – and hence the surgeons’ search for the seat of the human soul and the motion of life. In the motif of the corpse, Rembrandt performs a radical operation with paint layers that historical sources described with the terms “doodverwe” and “lyffverwe” (“dead color” and “body color”). Rembrandt’s pictorial formation is a distinctly complex answer to the soulless, lifeless corpse’s state of being, which has been reduced to no more than an image. At the same time, the dead body is the place in which Rembrandt reflects the act of painting as a way of working with the tension of embodiment and disembodiment, of giving and taking life, with color.
Toward a history of the Trecento diptych: Format, materiality, and mobility in a corpus of diptychs from Angevin Naples
Authors: Kozlowski Sarah K.
Published: January 2020

Laying the groundwork for a larger project, this essay brings together for the first time a working corpus of diptychs connected with the Angevin court in Naples in the later thirteenth and fourteenth centuries. Comprising both surviving diptychs and diptychs now lost but recorded in inventories, this body of material reveals that objects of this type were commissioned and collected in significant numbers at the Neapolitan court, in a range of sizes, mediums, and subjects, and were produced by workshops linked not only to Naples but also to central Italy, Genoa, and the Eastern Mediterranean. In turn, diptychs in Naples raise larger questions about the histories, materialities, and meanings of the format in the thirteenth and fourteenth centuries in Europe and the Mediterranean. Above all, the objects brought together here press us to set diptychs in motion through networks of artworks, artists, and patrons on the move across the Mediterranean.
Aperçues
Authors: Didi-Huberman Georges
Published: January 2020

This text attempts a new genre: the aperçue – from the French verb apercevoir, seeing in passing by, voir en passant. From Baudelaire’s Passante, the aperçues inherit the rhythm of appearing and disappearing and the emotion of seeing, which only unfolds in the temporality of memory and imagination. They are related to figures of afterlife and actualization such as Warburg’s Ninfa and Freud’s Gradiva, capturing ephemeral moments in which the long and discontinuous temporality of memory – and thus also a dimension of lament for the dead – is at work. Lastly, the aperçues are a literary genre, since images – especially those we never saw before remembering them – are made visible particularly through words, as we see reading James Joyce, Henri Michaux, and Yoko Tawada.
Ein Werk zweier Künstler? Paul Egell, Johann Peter Benckert und der Kruzifixus mit Maria Magdalena in der Propsteikirche St. Peter und Paul zu Potsdam
Authors: Fischbacher Thomas
Published: January 2020

The author suggests an attribution for two largely unknown Baroque sculptures inside the Church of St. Peter and Paul at Potsdam. The crucifixus, which has so far not been attributed to an artist, is shown to exhibit parallels to a 1716 work by Paul Egell. It remains unclear, however, whether the Potsdam crucifixus was also created by Egell himself or by Johann Peter Benckert, who congenially completed it in 1763 with a statue of the kneeling Maria Magdalena. The appealing depiction of the saint as an elegant sinner and penitent offers believers various possibilities for identification.
An Early Medieval Golden Reliquary Cross from Zagórzyce, Świętokrzyskie voiv. (PL)
Authors: Kubica-Grygiel Anna , Grygiel Michał
Published: January 2020

A unique golden cross with an embossed depiction of Christ crucified and filigree border was discovered without specific context at multicultural site 1 in Zagórzyce, Kazimierza Wielka District (PL). This artifact is a most impressive example of Early Medieval box-like cross-shaped pendants – unequivocally associated with Christian symbolism – and should be considered to have been a personal reliquary container. The box-like reliquary crosses that most closely parallel the find from Zagórzyce come from discoveries generally dated to the eleventh century. The Zagórzyce reliquary probably comes from a similar period, as it uses an archaic form of Greek cross with slightly flared-out arms, which is found among pendants dated to the tenth century or earlier. It was probably produced at the end of the tenth or in the eleventh century in an area west of Poland, perhaps in the Holy Roman Empire.
Ornamente transzendental und empirisch. Zu Kants Kritik der Urteilskraft und zu den Tätowierungen der »Neuseeländer«
Authors: Klammer Markus
Published: January 2020

By exploring the relation between the transcendental functions and the empirical and historical implications of the notion of »ornament« in Immanuel Kant’s Critique of the power of judgement, this article argues that Kant tried to establish the concept of ornament as a link between the pure formality of the aesthetic judgement and concrete empirical instances of beauty. Following a discussion of Kant’s emphasis on »exemplarity« and an analysis of his choice of examples of beauty, the article explores the conflict between Kant’s notion of the human body as an »ideal of beauty« and his famous disapproval of ornamental lines in the faces of Maori people. Finally, it considers the modes of representation of leading Maori, their garments, and their facial tā moko in the late nineteenth-century portraits of Gottfried Lindauer and Samuel E. Stuart, and advocates a dual reading of these portraits as both conforming to and contradicting the Kantian model of human beauty.
Per Ravenna trecentesca: nuove proposte per l’assetto architettonico di Santa Maria in Porto Fuori
Authors: Massaccesi Fabio
Published: January 2020

This contribution intends to draw attention to one of the most significant monuments of medieval Ravenna: the church of Santa Maria in Porto Fuori, which was destroyed during the Second World War. Until now, scholars have focused on the pictorial cycle known through photographs and attributed to the painter Pietro da Rimini. However, the architecture of the building has not been the subject of systematic studies. For the first time, this essay reconstructs the fourteenth-century architectural structure of the church, the apse of which was rebuilt by 1314. The data that led to the virtual restitution of the choir and the related rood screen are the basis for new reflections on the accesses to the apse area, on the pilgrimage flows, and on the view of the frescoes.
Jona und der Hai Zu einem frühneuzeitlichen Hai-Präparat zwischen Exegese und Naturgeschichte
Authors: Bauernfeind Robert
Published: January 2020

A seventeenth-century dry preparation of a porbeagle which was combined with a wooden sculpture of the prophet Jonah is analyzed using pictorial theories that emphasize the paradox of preparations being both subject and material of a visual representation. It explains the combination of Jonah and the shark by referring to speculations of early-modern natural history that the large fish that devoured Jonah must have been a shark. The preparation’s characteristic posture appears to be an adaptation of the depiction of a great white shark in Konrad Gessner’s Historia Animalium (1558), which had itself been drawn after a deformed dry preparation. The preparation of the porbeagle – probably made in an ecclesiastical context – thus represents less itself than a large shark.

The Seoul Metropolitan Area (SMA) has a population of 24 million and frequently experiences unhealthy levels of ozone (O3). In this work, measurements taken during the Korea-United States Air Quality Study (KORUS-AQ, 2016) are used to explore regional gradients in O3 and its chemical precursors, and an observationally-constrained 0-D photochemical box model is used to quantify key aspects of O3 production including its sensitivity to precursor gases. Box model performance was evaluated by comparing modeled concentrations of select secondary species to airborne measurements. These comparisons indicate that the steady state assumption used in 0-D box models cannot describe select intermediate species, highlighting the importance of having a broad suite of trace gases as model constraints. When fully constrained, aggregated statistics of modeled O3 production rates agreed with observed changes in O3, indicating that the box model was able to represent the majority of O3 chemistry.

Comparison of airborne observations between urban Seoul and a downwind receptor site reveal a positive gradient in O3 coinciding with a negative gradient in NOx, no gradient in CH2O, and a slight positive gradient in modeled rates of O3 production. Together, these observations indicate a radical-limited (VOC-limited) O3 production environment in the SMA. Zero-out simulations identified C7+ aromatics as the dominant VOC contributors to O3 production, with isoprene and anthropogenic alkenes making smaller but appreciable contributions. Simulations of model sensitivity to decreases in NOx produced results that were not spatially uniform, with large increases in O3 production predicted for urban Seoul and decreases in O3 production predicted for far-outlying areas. The policy implications of this work are clear: Effective O3 mitigation strategies in the SMA must focus on reducing local emissions of C7+ aromatics, while reductions in NOx emissions may increase O3 in some areas but generally decrease the regional extent of O3 exposure.

Translations of Non-Russian Soviet Literature in the Estonian Book Production (1940s-1980s)
Authors: Möldre Aile
Published: January 2020

This paper explores the dynamics of publishing of non-Russian Soviet literatures in Soviet Estonia, establishing the output of titles and the most popular source literatures. The analysis follows the position of Soviet national literatures during four periods in political history: the Stalinist years, the Thaw, Stagnation, and Perestroika. The study uses statistical yearbooks, bibliographies, archival material, as well as research literature as sources. The publishing of Soviet literature was strongly regulated by the publishing authorities and dependent on ideological directions. The analysis demonstrates that the proportion of the non-Russian Soviet literatures started to increase during the Thaw period, but the peak of its production was reached during the 1970s and the beginning of the 1980s due to official pressure. The total number of source literatures was 49, demonstrating the diversity of translation production, although they were represented equally. The top source literatures were Latvian, Lithuanian, and Ukrainian. The interest of the literary circles and reading audiences in the translations was rather weak, although the top authors attracted the attention of the more intellectual segment of readers.

A promising method for the treatment of effluents is the use of floating macrophytes. Ammoniacal nitrogen is a typical compound present in urban landfill leachates and its removal is important due its toxicity to several organisms. Therefore, the study evaluated Typha domingensis survival and nitrification potential artificially floating in domestic solid waste leachate. Plants were exposed for 35 days to leachate (100, 75 and 50 %) and to rainwater with N:P:K (control). Dissolved oxygen (DO) of the treatments was periodically measured, and ammoniacal nitrogen, nitrite and nitrate were analyzed before and after exposure. At the end of the experiment, plant survival rate was calculated. After two weeks, DO increased twice in the control, three times in 50 % leachate, four times in 75 % leachate, and eight times in 100 % leachate. At the end of the experiment, ammoniacal nitrogen was no longer detected, there was a significant reduction of nitrite, and a significant increase of nitrate in the treatments containing leachate. Plant survival was higher in those individuals exposed to 100 % leachate and decreased at lower leachate concentrations: 98 %, 94 %, 92 %, and 86 %. The study demonstrated that the ammoniacal nitrogen concentration of the leachate was not toxic to T. domingensis, and that it was efficient in the removal of this compound from the effluent, indicating that the species may be used artificially floating for the removal of this contaminant from domestic solid waste landfill leachate when in low concentrations.

Ecuador es uno de los países más ricos en biodiversidad y endemismo del mundo, y cerca de 3200 especies de plantas tienen usos medicinales. El objetivo de esta investigación fue evaluar la composición química y el efecto antimicrobiano del aceite esencial de Lasiocephalus ovatus Schltdl. (Asteraceae) colectada en la provincia de Chimborazo, Ecuador. Las partes aéreas de L. ovatus fueron sometidas a hidrodestilación para obtener el aceite esencial, el cual fue analizado mediante cromatografía de gases acoplada a espectrometría de masas. La actividad fue evaluada frente a cinco bacterias y una levadura usando la técnica de microdilución en caldo en microplacas de 96 pozos. El rendimiento del aceite fue de 0,05 % y 27 compuestos fueron identificados, representando 95,45 % de la composición total con un elevado contenido de monoterpenos oxigenados (52,17 %). Los compuestos mayoritarios fueron alcanfor (40,48 %) y 1,2,5,5-tetrametil-1,3-ciclopentadieno (11,90 %), seguido por p-menta-1,5-dien-8-ol (5,23 %) y 1,6-dimetilhepta-1,3,5-trieno (4,69 %). Las bacterias más sensibles a la acción del aceite fueron Staphylococcus aureus ATCC 25923 y Escherichia coli ATCC 25922 con concentraciones mínimas inhibitorias de 200-400 μg/mL y bactericidas de 800 μg/mL. La inhibición antimicrobiana frente a las bacterias Enterococcus faecalis ATCC 29212, Pseudomonas aeruginosa ATCC 27853, Klebsiella pneumoniae ATCC 700603 y la levadura Candida albicans ATCC 10231 fue baja, con un rango de concentración mínima inhibitoria de 800 a 6400 μg/mL. Este reporte representa un primer análisis de la actividad antimicrobiana del aceite de L. ovatus, por lo tanto, una contribución importante al estudio del género Lasiocephalus.

El embalse La Nitrera se encuentra localizado a 2140 m.s.n.m. en el municipio de Concordia, departamento de Antioquia (Colombia) y es la única fuente de abastecimiento de agua del municipio. La operación de un embalse sobre un sistema lótico afecta la estructura y ensamblaje de sus ecosistemas acuáticos. Esta investigación tuvo como propósito analizar la distribución de la biomasa de los macroinvertebrados acuáticos antes y después del embalse, con el fin de determinar el impacto de este sobre las comunidades hidrobiológicas. Para tal fin, se analizaron las variables hidrobiológicas en época seca, de lluvia y en diferentes periodos de transición entre el año 2016 y 2017. Se investigaron cuatro estaciones de monitoreo, realizando la determinación, conteo y definiendo el rol trófico de los macroinvertebrados acuáticos, además de un análisis termogravimétrico (TGA) de la biomasa. Con la información obtenida, se construyó un modelo trófico y se calculó la pérdida de energía calórica disponible de la biomasa (TGA). Los resultados evidenciaron que las comunidades de macroinvertebrados acuáticos presentan una modularidad similar entre ellas en las estaciones antes del embalse, y una modularidad diferente en la estación después del embalse. A través del índice de modularidad (modelo Ghepi) y el análisis TGA, se logró establecer que el embalse altera la cadena trófica de las comunidades de macroinvertebrados acuáticos.

La leishmaniosis es una enfermedad con gran impacto en salud pública dado a las características de las lesiones tegumentarias. El tratamiento experimental con terapia larval (TL) ha mostrado su uso potencial para la cura de la leishmaniosis, sin embargo, se han utilizado especies de moscas para TL en heridas causadas por Leishmania que no son de fácil colecta y cultivo bajo condiciones de laboratorio como Lucilia sericata o Calliphora vicina. El objetivo del presente trabajo fue usar una especie de mosca de fácil colecta, y de alta fecundidad como la Musca domestica para aplicarlas en TL de úlceras leishmánicas. Se realizó un estudio cuali-cuantitativo, de tipo descriptivo, mediante un diseño experimental empleado un modelo animal (Mesocricetus auratus), infectado con Leishmania amazonensis para evaluar el efecto terapéutico de la TL y comparar los resultados con el tratamiento químico antimonial de la droga experimental “Ulamina”. Se evidencia cicatrización y cura de la úlcera leishmánica en el 66,66 % de los animales tratados con TL en aplicación simple y del 100 % en TL combinada con Ulamina. El uso combinado de TL+Ulamina, muestra un efecto potenciador de la cura clínica de las úlceras, pero con persistente inflamación. Se observó una efectividad óptima de la TL con M. domestica, sobre las úlceras, aunque no se evidenció un efecto sobre L. amazonensis dado a la presencia de amastigotes en los frotis y a los amplicones obtenidos de 480 bp desde las improntas de los animales.
