The Shrine of ʿAbd al-Qādir al-Jīlānī in Baghdad & the Shrine of ʿAbd al-ʿAzīz al-Jīlānī in ʿAqra: Mapping the multiple orientations of two Qādirī Sufi shrines in Iraq

This thesis charts the stakeholder communities, physical environment and daily life of two little studied Qādiriyya Sufi shrines associated with Shaikh ʿAbd al-Qādir al-Jīlānī (1077 – 1165 AD), a 12th century Ḥanbalī Muslim theologian and the posthumous founder of one of the oldest Sufi orders in Islam. The first shrine is based in Baghdad and houses his burial chamber; and the second shrine, on the outskirts of the city of ‘Aqra in the Kurdish region of northern Iraq, is that of his son Shaikh ʿAbd al-ʿAzīz (died 1206 AD). The latter was also known for lecturing in Ḥanbalī theology in the region, and venerated for this as well as his association with Shaikh ʿAbd al-Qādir. Driven by the research question “What shapes the identity orientations of these two Qādiriyya Sufi shrines in modern times?” the findings presented here are the result of field research carried out between November 2009 and February 2014. This field research revealed a complex context in which the two shrines existed and interacted, influenced by both Sufi and non-Sufi stakeholders who identified with and accessed these shrines to satisfy a variety of spiritual and practical needs, which in turn influenced the way each considered and viewed the two shrines from a number of orientations. These overlapping orientations include the Qādirī Sufi entity and the resting place of its patron saint; the orthodox Sunnī mosque with its muftī-imams, who are employed by the Iraqi government; the local Shīʿa community’s neighbourhood saint’s shrine and its destination for spiritual and practical aid; and the local provider of welfare to the poor of the city (soup kitchen, funeral parlour and electricity-generation amongst other services). The research findings also revealed a continuously changing and adapting Qādirī Sufi scene not immune from the national and regional socio-religio-political environments in which the two shrines exist: a non-Sufi national political class vying to influence and manipulate these shrines for their own purposes; and powerful national sectarian factions jostling to do the same. The mixture of stakeholders using and associating with the two shrines were found to be influential shapers of these entities, both physically and spiritually. Through encountering and interacting with each other, most stakeholders contributed to maintaining and rejuvenating the two shrines, but some also sought to adapt and change them driven by their particular orientation’s perspective.

Structural and Biochemical Characterization of Peroxiredoxin Q beta from Xylella fastidiosa CATALYTIC MECHANISM and HIGH REACTIVITY

The phytopathogenic bacterium Xylella fastidiosa is the etiological agent of various plant diseases. To survive under oxidative stress imposed by the host, microorganisms express antioxidant proteins, including cysteine-based peroxidases named peroxiredoxins. This work is a comprehensive analysis of the catalysis performed by PrxQ from X. fastidiosa (XfPrxQ) that belongs to a peroxiredoxin class still poorly characterized and previously considered as moderately reactive toward hydroperoxides. Contrary to these assumptions, our competitive kinetics studies have shown that the second-order rate constants of the peroxidase reactions of XfPrxQ with hydrogen peroxide and peroxynitrite are in the order of 107 and 106 M(-1) s(-1), respectively, which are as fast as the most efficient peroxidases. The XfPrxQ disulfides were only slightly reducible by dithiothreitol; therefore, the identification of a thioredoxin system as the probable biological reductant of XfPrxQ was a relevant finding. We also showed by site-specific mutagenesis and mass spectrometry that an intramolecular disulfide bond between Cys-47 and Cys-83 is generated during the catalytic cycle. Furthermore, we elucidated the crystal structure of XfPrxQ C47S in which Ser-47 and Cys-83 lie similar to 12.3 angstrom apart. Therefore, significant conformational changes are required for disulfide bond formation. In fact, circular dichroism data indicated that there was a significant redox-dependent unfolding of alpha-helices, which is probably triggered by the peroxidatic cysteine oxidation. Finally, we proposed a model that takes data from this work as well data as from the literature into account.

Evaluación de los cambios dentarios y su influencia en los tejidos blandos de pacientes tratados con sistema Damon Q y MBT

Se realizó una investigación con el objetivo de establecer los cambios dentarios y evaluar la influencia de estos en los tejidos blandos comparando pacientes tratados con sistema Damon Q (N=23) y MBT (N=16). Se seleccionó una muestra de estudio conformada por 39 individuos siendo 28 mujeres y 11 varones de edades comprendidas entre 11 y 26 años. Se registraron radiografías cefálicas laterales digitales tomadas antes y después de concluido el tratamiento. Las inclinaciones de los incisivos superiores e inferiores así como las alteraciones del perfil facial fueron medidas mediante el Software de análisis cefalométrico Nemotec Dental. Para determinar los cambios en los tejidos duros y blandos se aplicó la prueba T-Student verificándose diferencias estadísticamente significativas (p < 0,05) para los dos sistemas en las variables: ángulo incisivo maxilar, mandibular, posición del labio inferior según el plano estético de Ricketts y el de Burstone. La correlación existente entre los cambios en la inclinación de los incisivos y la posición labial, se evaluó mediante el coeficiente de relación de Pearson encontrando para el sistema Damon una correlación entre la posición del incisivo superior y la del labio superior e inferior, la posición del incisivo inferior tuvo una correlación moderada con el labio inferior, con la técnica MBT se encontró una relación moderada entre la posición del incisivo superior y el labio inferior. Se concluyó que existen cambios postratamiento en la posición de los incisivos, así como protrusión labial inferior hallando relación entre la inclinación vestibular de los incisivos y el movimiento de los labios en ambas técnicas

On the optimaL response of q-vortex

Wingtip vortices represent a hazard for the stability of the following airplane in airport highways. These flows have been usually modeled as swirling jets/wakes, which are known to be highly unstable and susceptible to breakdown at high Reynolds numbers for certain flow conditions, but different to the ones present in real flying airplanes. A very recent study based on Direct Numerical Simulations (DNS) shows that a large variety of helical responses can be excited and amplified when a harmonic inlet forcing is imposed. In this work, the optimal response of q-vortex (both axial vorticity and axial velocity can be modeled by a Gaussian profile) is studied by considering the time-harmonically forced problem with a certain frequency ω. We first reproduce Guo and Sun’s results for the Lamb-Oseen vortex (no axial flow) to validate our numerical code. In the axisymmetric case m = 0, the system response is the largest when the input frequency is null. The axial flow has a weak influence in the response for any axial velocity intensity. We also consider helical perturbations |m| = 1. These perturbations are excited through a resonance mechanism at moderate and large wavelengths as it is shown in Figure 1. In addition, Figure 2 shows that the frequency at which the optimal gain is obtained is not a continuous function of the axial wavenumber k. At smaller wavelengths, large response is excited by steady forcing. Regarding the axial flow, the unstable response is the largest when the axial velocity intensity, 1/q, is near to zero. For perturbations with higher azimuthal wavenumbers |m| > 1, the magnitudes of the response are smaller than those for helical modes. In order to establish an alternative validation, DNS has been carried out by using a pseudospectral Fourier formulation finding a very good agreement.

Révolution P.Q. : figures révolutionnaires québécoises

Mon mémoire de recherche-création se divise en deux volets. Le premier volet est une partie théorique qui est partagée en trois parties. Dans l’introduction, je parle de la figure iconique que renvoie l’image de « Che » Guevara. Dans la première partie, je fais une distinction entre une révolution et une révolte. Ensuite, je fais un résumé de différents ouvrages concernant les groupes contestataires dans la littérature québécoise et comment les auteurs ont parlé de révolte et d’identité plutôt que de faire un portrait du révolutionnaire québécois. Parallèlement, je démontre comment le cinéma québécois a dépeint les révolutionnaires, soit de manière ironique et cynique, soit en démontrant le côté humain et héroïque des contestataires. Dans la deuxième partie, j’explique pourquoi j’ai décidé de faire un film documentaire sur les figures de la révolution au Québec. Je parle de mes choix esthétiques, du choix des intervenants, de la voix au cinéma et de la puissance des archives. Mon film documentaire traite spécifiquement de la question des figures contestataires et est complémentaire du mémoire écrit. Dans mon film, j’essaie surtout de démontrer s’il existe des figures contestataires iconiques québécoises qui renvoient à l’idée de la révolution, comme la célèbre image et l’individu qu’était Ernesto « Che » Guevara. Puisqu’il a inspiré des générations de contestataires dont ceux du Québec dans les années 1960 et 1970, quelles personnalités québécoises peuvent être identifiées comme étant des icônes de la révolution?

GENETIC VARIATION, LOCAL ADAPTATION AND POPULATION STRUCTURE IN NORTH AMERICAN RED OAK SPECIES, QUERCUS RUBRA L. AND Q. ELLIPSOIDALIS E. J. HILL

Forest trees, like oaks, rely on high levels of genetic variation to adapt to varying environmental conditions. Thus, genetic variation and its distribution are important for the long-term survival and adaptability of oak populations. Climate change is projected to lead to increased drought and fire events as well as a northward migration of tree species, including oaks. Additionally, decline in oak regeneration has become increasingly concerning since it may lead to decreased gene flow and increased inbreeding levels. This will in turn lead to lowered levels of genetic diversity, negatively affecting the growth and survival of populations. At the same time, populations at the species’ distribution edge, like those in this study, could possess important stores of genetic diversity and adaptive potential, while also being vulnerable to climatic or anthropogenic changes. A survey of the level and distribution of genetic variation and identification of potentially adaptive genes is needed since adaptive genetic variation is essential for their long-term survival. Oaks possess a remarkable characteristic in that they maintain their species identity and specific environmental adaptations despite their propensity to hybridize. Thus, in the face of interspecific gene flow, some areas of the genome remain differentiated due to selection. This characteristic allows the study of local environmental adaptation through genetic variation analyses. Furthermore, using genic markers with known putative functions makes it possible to link those differentiated markers to potential adaptive traits (e.g., flowering time, drought stress tolerance). Demographic processes like gene flow and genetic drift also play an important role in how genes (including adaptive genes) are maintained or spread. These processes are influenced by disturbances, both natural and anthropogenic. An examination of how genetic variation is geographically distributed can display how these genetic processes and geographical disturbances influence genetic variation patterns. For example, the spatial clustering of closely related trees could promote inbreeding with associated negative effects (inbreeding depression), if gene flow is limited. In turn this can have negative consequences for a species’ ability to adapt to changing environmental conditions. In contrast, interspecific hybridization may also allow the transfer of genes between species that increase their adaptive potential in a changing environment. I have studied the ecologically divergent, interfertile red oaks, Quercus rubra and Q. ellipsoidalis, to identify genes with potential roles in adaptation to abiotic stress through traits such as drought tolerance and flowering time, and to assess the level and distribution of genetic variation. I found evidence for moderate gene flow between the two species and low interspecific genetic differences at most genetic markers (Lind and Gailing 2013). However, the screening of genic markers with potential roles in phenology and drought tolerance led to the identification of a CONSTANS-like (COL) gene, a candidate gene for flowering time and growth. This marker, located in the coding region of the gene, was highly differentiated between the two species in multiple geographical areas, despite interspecific gene flow, and may play a role in reproductive isolation and adaptive divergence between the two species (Lind-Riehl et al. 2014). Since climate change could result in a northward migration of trees species like oaks, this gene could be important in maintaining species identity despite increased contact zones between species (e.g., increased gene flow). Finally I examined differences in spatial genetic structure (SGS) and genetic variation between species and populations subjected to different management strategies and natural disturbances. Diverse management activities combined with various natural disturbances as well as species specific life history traits influenced SGS patterns and inbreeding levels (Lind-Riehl and Gailing submitted).

Q certification and tourist satisfaction in the Spanish hotels

Spain has been working on improving the competitiveness of its tourist destinations, focusing on the quality of the service. This paper analyzes whether the efforts made by the tourism establishment to achieve the Q brand are perceived by their guests in a general way or in a particular dimension of the service. Statistical contrasts of mean differences are performed to evaluate if the score of a Q hotel is greater than that of a non-Q hotel. The results show that the Q brand is related to the satisfaction of the customer in a different way according the analyzed dimension.

Lecturas de la prensa popular: Un estudio de recepción del periódico Q'hubo en la localidad de Kennedy en Bogotá

En este trabajo de grado se aborda la relación entre las audiencias y los medios a partir de un estudio de recepción del diario Q’hubo en los sectores populares de Bogotá, específicamente en la localidad de Kennedy de esta ciudad. El estudio reconoce que las formas determinadas de interactuar con los medios están atadas a los contextos, las instituciones y los entornos culturales y sociales desde los que lector construye su realidad y se inserta en la sociedad actual. Por lo mismo, se nutre de estos elementos para entender los procesos de recepción a través de las formas cotidianas de consumo del diario Q’hubo frente al contexto mediático actual. Se sustenta que el Q’hubo se comunica con sus lectores combinando aspectos clásicos de la prensa popular y adaptando aspectos de diseño y lenguaje aportados por los nuevos medios. Lo que a su vez se relaciona con apropiaciones, usos y modos de leer de la audiencia, que reivindica interacciones tradicionales y desarrolla interacciones emergentes gracias a la convergencia de las tecnologías con la cultura letrada, oral y visual.

Láser Q-Switched en el manejo de ocronosis exógena: revisión sistemática de la literatura

Antecedentes: La ocronosis Exógena (OE) es una enfermedad subdiagnosticada y de difícil manejo (1). El láser Q-Switched (QS) surge como una alternativa para el tratamiento de esta (2). Objetivo: Describir las características de los pacientes, del láser QS y los desenlaces en el tratamiento de OE. Métodos: Se realizó una búsqueda de la literatura en las bases PubMed, Embase, PMC, Scielo, Elselvier, BMJ Case Reports, Journal of Medical Case Reports, Cases Journal e International Medical Case Reports Journal, desde enero del 2000 a marzo del 2016, pacientes con ocronosis exógena, 18 a 70 años, tratados con láser QS. Los artículos fueron evaluados mediante la herramienta de evaluación de validez y valor educativo de reportes de caso descrito por Pierson (3). Resultados: Se encontraron 256 artículos, 63 fueron seleccionados: 28 repetidos y 31 no cumplieron criterios de inclusión. Se escogieron 4 artículos que reportan 12 casos de pacientes con ocronosis exógena diagnosticada mediante estudio histopatológico y tratada con láser QS. Discusión: Hay poca experiencia con el láser QS en OE. En la práctica clínica se usa para tatuajes y patologías pigmentarias dérmicas con resultados satisfactorios. El pigmento dérmico en OE y la corta duración de pulso de láser QS, podrían ser el pilar de tratamiento para OE. Conclusión: El láser QS puede ser útil para el tratamiento en OE, con nivel de evidencia 3 y grado de recomendación D. Se sugiere realizar estudios clínicos con mayor grado de evidencia.
