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

Abstract
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

Abstract
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

Abstract
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

Abstract
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

Abstract
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

Abstract
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

Abstract
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.
Edgardo Pérez Morales. No Limits to Their Sway. Cartagena’s Privateers and the Masterless Caribbean in the Age of Revolutions.
Authors: Terrien Nicolas 
Published: January 2020

Este libro aporta una contribución adicional y de notable interés a la imagen que se está formando actualmente de una historia por naturaleza transimperial, la del Caribe revolucionario bajo el prisma del corso marítimo. Su autor, el historiador colombiano Edgardo Pérez Morales, se incluye en un ámbito historiográfico marcado primeramente por Julius S. Scott —a quien dedica el libro— y por Marcus Rediker. Por lo tanto, no es de extrañar que, en nueve capítulos breves y dinámicos, preste especial atención a la tensión establecida entre los pares libertad/esclavitud y mar/tierra, así como a lo que también él llama el “Caribe sin dueño” (“Masterless Caribbean”).

Published: January 2020

Objetivo: esta investigación evaluó la reproducibilidad en el diagnóstico imagenológico de PA en dientes del maxilar superior a partir de 60 CBCT tomadas en una institución clínica en una ciudad intermedia en Colombia. Métodos: el estudio fue realizado por dos observadores previamente calibrados de CBCT del maxilar superior que contenían dientes permanentes con ápice cerrado, correspondientes a adultos mayores de 18 años de edad. La presencia o ausencia de periodontitis apical se analizó utilizando el índice CBCT PAI. La información registrada fue relacionada con variables de interés. Resultados: la reproducibilidad entre los evaluadores fue sustancial o perfecta. La prevalencia de periodontitis apical encontrada fue del 21,6%, en los dientes con tratamiento de endodoncia 12,4% y en los dientes sin tratamiento endodóntico 9,2%. Conclusiones: la tomografía CBCT proporciona al clínico información que permite una mayor claridad en la fase de diagnóstico. Los dientes con la mayor prevalencia de PA fueron el primer molar y el primer premolar superior izquierdo respectivamente.

El ‘volteo de tierras’: modificaciones irregulares a los planes de ordenamiento territorial en Cundinamarca, Colombia
Authors: Meza Cuesta Jhosef Eduardo 
Published: January 2020

Las modificaciones irregulares de los planes de ordenamiento territorial con fines de lucro, o ‘volteo de tierras’ es un caso de corrupción que se investiga a nivel judicial desde hace más de dos años y que se presenta en varios municipios del Departamento de Cundinamarca como Mosquera, Madrid, Chía, Funza, entre otros. Aunque hay involucrados y las investigaciones han mostrado avances, las posiciones políticas de diversos gobiernos –en particular los de Bogotá y Cundinamarca- no han sido suficientes y sus actuaciones no logran resolver la situación. El objetivo de este artículo es explicar sus principales características, analizar las causas estructurales de la problemática, y algunos de sus efectos legales, urbanísticos y ambientales. Ante la ausencia de investigaciones académicas sobre el tema, se realizó una revisión de prensa en revistas y periódicos digitales en los que se describen las características del fenómeno y los actores implicados. Luego se revisaron diversas normas sobre ordenamiento territorial para explicar por qué este es ilegal. Por último, se analizaron varios informes de organismos públicos como el IDEAM y el IGAC para determinar, desde opiniones de expertos, sus potenciales implicaciones, como la reducción del suelo de vocación agrícola y de protección ambiental, inconvenientes en la red de servicios públicos, y construcción de vivienda de baja calidad.

Heterogeneidad y escisión política: algunos aspectos claves a considerar en un gobierno metropolitano de Bogotá-sabana
Authors: Gómez Puentes Sabina 
Published: January 2020

El interés de está trabajo se concentra en dos propósitos generales. El primero, comprender qué es la metropolización y en qué se distancia de la manera en que se ha entendido lo urbano. El segundo, identificar algunos de los elementos de gobierno que no pueden ser ajenos a los diferentes actores territoriales que buscan hacer gestión de lo metropolitano en Bogotá-Sabana. Busca principalmente desenmarcar el tema de posturas técnicas y del enfoque de proyectos para reflexionar sobre la escala metropolitana como expresión del pluralismo, de las tensiones socioeconómicas que han configurado el desarrollo urbano de la ciudad y como espacio para el ejercicio del poder y la representación de diferentes intereses políticos. Para tales fines, además de la elaboración de un breve marco conceptual en el primer apartado, en el segundo, se hace una revisión de notas de prensa y de los planes de ordenamiento territorial para obtener pistas sobre cómo ha sido el juego político para gobernar el territorio. Finalmente se ofrecen las conclusiones generales del ejercicio.
Determination of plantain crops associated with coffee environmental impacts on agroecosystems by means of Life Cycle Assessment: case study in the Southwest of Antioquia (Colombia)
Authors: Valenzuela Vergara Elisa Esther , Castañeda Sánchez Darío Antonio , Cano Londoño Natalia Andrea 
Published: January 2020

Plantain and coffee are basic foodstuff of Colombian family standard basket, constituting important sources in the dynamism of the economy of the country. Given the importance of these products, five environmental impacts: global warming, aquatic eutrophication, terrestrial acidification, aquatic ecotoxicity and use of soil were evaluated in three plantain crops associated with coffee in Antioquia Southwest (Colombia), for this purpose RECIPE 2008 method with a cradle to gate approach was used. Surveys and interviews applied to owners and employees of the farms, and to agents related to the production chains were carried out to obtain primary data, secondary data were taken from Ecoinvent 3.1 database. Consumption of resources and emissions were assigned to a functional unit of 1 kg of plantain and 1 kg of dry parchment coffee. Production systems consisted of four stages: establishment/propagation, production, postharvest and distribution. Plantain system generated less impact than coffee, and the stages that contributed the most to the environmental burden on impact categories in both crops were establishment/propagation and production. This is mainly due to the manufacture and the use of fertilizers.
Effects of strain on La0.67-x Prx Ca0.33 MnO3, LaMn1-x Cox O3 and LaMn1-x Nix O3 magnetite samples
Authors: Olarte Torres Javier Alberto , Cifuentes Arcila María Cristina , Suárez Moreno Harvey Andrés 
Published: January 2020

This paper presents the results obtained from the synthesis and morphological characterization of different magnetite samples: La0.67-x Prx Ca0.33 MnO3.LaMn1-x Cox O3 and LaMn1-x Nix O3 at 0.13 ≤ 𝑥𝑥 ≤ 0.67 produced by a solid-state reaction mechanism and 𝐿𝐿𝐿𝐿𝑀𝑀𝑀𝑀1−𝑥𝑥(𝐶𝐶𝐶𝐶/𝑁𝑁𝑁𝑁)𝑥𝑥𝑂𝑂3 at 0.0 ≤ 𝑥𝑥 ≤ 0.5 produced by the sol-gel method. These samples were characterized using X-ray diffraction spectroscopy and by measuring electric resistivity and magnetic susceptibility which were carried out as a function of temperature. Notably, the effects of strain and compressive strength on the lattices of magnetite samples were highly dependent on the concentration of 𝑃𝑃𝑟𝑟, 𝐶𝐶𝐶𝐶, and 𝑁𝑁𝑁𝑁. Moreover, the transition temperatures of metal-insulator and ferromagnetic-paramagnetic phases also largely depend on these strength effects, e.g., at higher concentrations of 𝑃𝑃𝑟𝑟, effects of increased strain strength were observed, relocating the shifts of ferromagnetic-paramagnetic transitions to lower temperatures. On the other hand, effects of increased compressive strength were observed at higher concentrations of 𝑁𝑁𝑁𝑁 and 𝐶𝐶𝐶𝐶, relocating the shifts of ferromagnetic-paramagnetic and metal-insulator transitions to higher temperatures.

Comparison of biogas production obtained from samples of Mitú and Sibundoy municipal solid waste
Authors: Triana Jiménez Kelly Marcela , Velasquez Mario Enrique 
Published: January 2020

This study compares the calorific power of biogas obtained from the municipal solid waste (MSW)of two towns in Colombia,whose populations are affected by deficiencies in the supply of electricity. The production of biogas would represent an importantopportunity to meet these needs, taking advantage of the solid waste generated, in whose composition organic material predominates(45 %). For this purpose, MSW samples were taken from the municipalities of Mitú (Vaupés) and Sibundoy (Putumayo), in orderto establish their relevance to produce biogas. For each sample, the organic waste was characterized in terms of its macroscopiccomposition, moisture content, ash, volatile and total solids. Subsequently, the composition of biogas obtained was determinedfrom anaerobic digestion tests with biological sludge as inoculum in different proportions and the calorific value of the gas wascalculated. It was found that organic waste from both municipalities is suitable to produce biogas due to the physicochemicalcharacteristics of the samples, the high methane content generated and, therefore, the satisfactory calorific power for its use in theproduction of electrical energy.
