Una planta sin clásicos. La berenjena en la farmacología medieval y renacentista

La berenjena (Solanum melongena L.) es una planta solanácea de múltiples variedades, cuyos ancestros salvajes se sitúan en Indochina y el este de África. Su cultivo fue muy temprano en zonas de China e India. Aun así, no se extendió al Occidente antiguo ni apenas se conoció, de ahí su ausencia en los textos clásicos de botánica y farmacología. Fueron los árabes quienes llevaron el cultivo de la planta por el Norte de África y Al-Andalus, de donde pasó ya a Europa. Los primeros testimonios occidentales de la berenjena aparecen en traducciones latinas de textos árabes, para incorporarse luego a la literatura farmacológica medieval y, más tarde ya, a la del Renacimiento, que empezó a tratar de ella por su posible parecido con una especie de mandrágora. Pese a que se le reconocían algunas virtudes medicinales, siempre se la tuvo bajo sospecha por ser de sabor poco agradable, indigesta y causante de algunas afecciones. Solo los botánicos de finales del Renacimiento describirían la planta y sus variedades con criterios más «científicos» y botánicos, ya sin apenas intereses farmacológicos.

Patronazgo literario en la Inglaterra medieval (ss. VII-XIV) : una visión panorámica

Este artículo ofrece una aproximación panorámica a la práctica del patronazgo literario en Inglaterra desde el s. VII al XIV. Durante el período anglosajón las relaciones de patronazgo fueron principalmente de dos tipos: (1) un poeta o scop que quedaba vinculado a una corte (p. ej. Déor) y (2) un intérprete o gleoman que desarrollaba su actividad no creativa de forma itinerante ante públicos diversos (p. ej. Wídsid). Caso aparte es el del pastor Cadmon, quien por intervención divina se convirtió en poeta bíblico y fue acogido en un monasterio. Tras la conquista normanda se introdujo un modelo de patronazgo aristocrático que favoreció la aparición de la figura del autor (p. ej. Wace) que componía sus obras en anglonormando, mientras el inglés era usado por juglares anónimos para deleite de las clases populares. La literatura en lengua inglesa no asistiría a la aparición de sus primeros autores (p. ej. Chaucer y Gower) hasta el siglo XIV, gracias en parte al patronazgo del rey Ricardo II

Um olhar sobre o castelo de Noudar: do castelo medieval à ruína: Proposta de valorização do lugar

O Castelo de Noudar está implantado num íngreme promontório da herdade da Coitadinha, a Noroeste de Barrancos, integrando o atual Parque da Natureza de Noudar. Construído a partir de 1303, foi alvo de diversas transformações ao longo do tempo, para responder às exigências militares de cada época, e chega aos nossos dias num avançado estado de decadência física. A investigação desenvolvida assenta, em grande parte, no desenho: de Noudar a uma escala territorial, como elemento que participa numa rede fortificada complexa; da evolução morfológica e funcional, que nos permite ter noção das várias configurações do castelo ao longo dos séculos; num desenho propositivo que desenvolve uma estratégia para valorização do lugar e do seu património material e imaterial. Hoje é fundamental compreender como as valências do Parque e da fortaleza se podem cruzar? Este trabalho pretende refletir sobre possibilidades de valorização para contrariar a degradação em que a fortaleza se encontra; ABSTRACT: The Noudar Castle is located in a steep promontory in the herdade da Coitadinha, Northeast from Barrancos, part of the Natural Park of Noudar. Its construction began in 1303, and underwent several transformations throughout its existence, adapting to the military advancements thru out the ages. Today, it shows an advanced state of decay. The investigation is focused on the design of Noudar on a territorial scale, taking part in a complex network of fortified systems; its functional and morphological evolution, which allows us to comprehend the configurations of the castle throughout the centuries; and on a proposed design that develops a strategy to enhance and bring value to this place and its material and non-material heritage. Today it's crucial to comprehend how can the values of the Park and fortress intertwine. This thesis reflects on the possibilities of valuing this site, counter acting the decay which has fallen upon it.

Near-infrared Instrumentation For Rapid-response Astronomy

Ɣ-ray bursts (GRBs) are the Universe's most luminous transient events. Since the discovery of GRBs was announced in 1973, efforts have been ongoing to obtain data over a broader range of the electromagnetic spectrum at the earliest possible times following the initial detection. The discovery of the theorized ``afterglow'' emission in radio through X-ray bands in the late 1990s confirmed the cosmological nature of these events. At present, GRB afterglows are among the best probes of the early Universe (z ≳ 9). In addition to informing theories about GRBs themselves, observations of afterglows probe the circum-burst medium (CBM), properties of the host galaxies and the progress of cosmic reionization. To explore the early-time variability of afterglows, I have developed a generalized analysis framework which models near-infrared (NIR), optical, ultra-violet (UV) and X-ray light curves without assuming an underlying model. These fits are then used to construct the spectral energy distribution (SED) of afterglows at arbitrary times within the observed window. Physical models are then used to explore the evolution of the SED parameter space with time. I demonstrate that this framework produces evidence of the photodestruction of dust in the CBM of GRB 120119A, similar to the findings from a previous study of this afterglow. The framework is additionally applied to the afterglows of GRB 140419A and GRB 080607. In these cases the evolution of the SEDs appears consistent with the standard fireball model. Having introduced the scientific motivations for early-time observations, I introduce the Rapid Infrared Imager-Spectrometer (RIMAS). Once commissioned on the 4.3 meter Discovery Channel Telescope (DCT), RIMAS will be used to study the afterglows of GRBs through photometric and spectroscopic observations beginning within minutes of the initial burst. The instrument will operate in the NIR, from 0.97 μm to 2.37 μm, permitting the detection of very high redshift (z ≳ 7) afterglows which are attenuated at shorter wavelengths by Lyman-ɑ absorption in the intergalactic medium (IGM). A majority of my graduate work has been spent designing and aligning RIMAS's cryogenic (~80 K) optical systems. Design efforts have included an original camera used to image the field surrounding spectroscopic slits, tolerancing and optimizing all of the instrument's optics, thermal modeling of optomechanical systems, and modeling the diffraction efficiencies for some of the dispersive elements. To align the cryogenic optics, I developed a procedure that was successfully used for a majority of the instrument's sub-assemblies. My work on this cryogenic instrument has necessitated experimental and computational projects to design and validate designs of several subsystems. Two of these projects describe simple and effective measurements of optomechanical components in vacuum and at cryogenic temperatures using an 8-bit CCD camera. Models of heat transfer via electrical harnesses used to provide current to motors located within the cryostat are also presented.

An Assessment of Professional Development for Astronomy and Physics Faculty: Expanding Our Vision of How to Support Faculty's Learning About Teaching

In this thesis, we will explore approaches to faculty instructional change in astronomy and physics. We primarily focus on professional development (PD) workshops, which are a central mechanism used within our community to help faculty improve their teaching. Although workshops serve a critical role for promoting more equitable instruction, we rarely assess them through careful consideration of how they engage faculty. To encourage a shift towards more reflective, research-informed PD, we developed the Real-Time Professional Development Observation Tool (R-PDOT), to document the form and focus of faculty's engagement during workshops. We then analyze video-recordings of faculty's interactions during the Physics and Astronomy New Faculty Workshop, focusing on instances where faculty might engage in pedagogical sense-making. Finally, we consider insights gained from our own local, team-based effort to improve a course sequence for astronomy majors. We conclude with recommendations for PD leaders and researchers.

Doctrina jurídica y práctica social del matrimonio medieval según Las Partidas

En este trabajo se analizan las ideas sobre el matrimonio en Las Partidas, la más importante manifestación del universo cultural alfonsí, tanto en su expresión jurídica como en su significado social y antropológico. Se inicia con una exposición del modelo matrimonial existente en la corte castellana en tiempos de Fernando III, según se recoge en la Primera Crónica General. A continuación se contempla el matrimonio en su relación con la codificación del parentesco y el desenvolvimiento de la conyugalidad como comportamiento humano, considerados de forma atemporal, para después exponer, en síntesis, la evolución de las teorías sobre el matrimonio durante la Edad Media hasta el siglo XIII. La segunda parte del trabajo estudia la doctrina del matrimonio en Las Partidas agrupada en los siguientes apartados: Celebración del matrimonio. Requisitos para su validez, edad núbil, sexualidad. Uniones “no justas”. Ruptura del matrimonio. Nulidad en razón de parentesco. Impotencia. Divorcio y separación.

Echoes of Greek Tragedy in Medieval Literature: The Case of Oedipus

In approaching this issue, it will be helpful to use two analytically distinct methods, to wit, the diachronic, which allows us to speculate about how the myth reached the hands of Lydgate (Guerin 2005, 183–191); and the synchronic, to clarify the similarities and differences between the two authors. Thus, approaching the subject diachronically, the first pages of this paper will attempt to delineate the main milestones in the long tradition of the myth of Oedipus, beginning from the time of Ancient Rome; and, afterwards, a synchronic analysis will examine various motifs as they have survived, disappeared or been transformed in the medieval poem. The final part will explore the possible reasons for these changes.

Opisthorchiasis in infant remains from the medieval Zeleniy Yar burial ground of XII-XIII centuries AD

We present a paleoparasitological analysis of the medieval Zeleniy Yar burial ground of the XII-XII centuries AD located in the northern part of Western Siberia. Parasite eggs, identified as eggs of Opisthorchis felineus, were found in the samples from the pelvic area of a one year old infant buried at the site. Presence of these eggs in the soil samples from the infant’s abdomen suggests that he/she was infected with opisthorchiasis and imply consumption of undercooked fish. Ethnographic records collected among the population of the northern part of Western Siberia reveal numerous cases of feeding raw fish to their children. Zeleniy Yar case of opisthorchiasis suggests that this dietary custom has persisted from at least medieval times.
