Imagen de apoyo de Radiographic and ultrasonographic assessment of the distal forelimb in lame horses = Aspectos radiográficos y ultrasonográficos de las regiones que causan claudicación en la porción distal de los miembros torácicos de equinos

Por: Juan José Restrepo Bucheli | Fecha: 2018

The digits on equine forelimbs withhold a great variability of weight overload, mainly caused by motion. Bones are linked through tendons and ligaments, which receive the greatest loads during the different phases of the stride. Ultrasound has become an important aid on evaluating these structures, since they are highly prone to lesion. To that purpose, we ought to evaluate tendinous and ligamentous lesions associated to distal limb lameness in horses by ultrasonographic examination of the distal limb. Furthermore, we studied the incidence of ungular cartilages ossification through radiographic examination. Tendinous and ligamentous structures were assessed on longitudinal and transversal planes. Colateral ligaments of the distal interfalangeal joints were also evaluated at the dorsal aspect of the limb, over the coronary band of the hoof. Aditionally, transcuneal examinaition was performed following trimming the hoof and levelling the frog. Dorsopalmar radiographs of both forelimbs were taken in order to grade ossification of the ungular cartilages by using the Ruohoniemi scale. Palmar structures such as oblique sesamoidean ligaments (46,66%), straight sesamoidean ligament (53,33%) also presented ultrasonographic signs of disruption. Suprasesamoidean, sesamoidean and infrasesamoidean lessions were observed on the deep digital flexor tendon. There were correspondence between the grade 1 and 3 of the ossification of the ungular cartilages and the desmopathy of the collateral ligament of the distal interphalangeal joint, characterized by loss of the echographic pattern and the presence of fibrotic or mineralized areas. The desmopathies of the collateral ligaments of the distal interphalangeal joint, does not always have correspondence relationship with the ossification of the ipsilateral ungular cartilage. When the ossification of the cartilages is severe, can disturb the ability to dampen.

Imagen de apoyo de Sinthetic cast and transcortical pins to reduce a fracture in the third metacarpal bone in a foal = Yeso sintético y clavos transcorticales para reducir una fractura en el hueso tercer metacarpiano en una potra

Por: Juan José Restrepo Bucheli | Fecha: 2018

The equines have an appendicular skeleton which has a group of long bones, to develop high speeds, and avoid predators. These bones are targets for traumas and fractures. Their treatment and prognosis are direct influenced by the body weight. The external skeletal fixation is a therapeutic method used in horses for the treatment of third metacarpal / metatarsal bone fractures, and conminuted distal fractures. The external fixation methods mix the use of transcortical pins and a periferic structure, to direct the force to the proximal portion of the fractured region while the limb bears weight, a very important aspect in horses, because they need to bear weight although it exists an osseus injury. With the use of a sinthetic cast, three transcortical smooth pins with 4 mm of diameter, inserted with a range of 15 to 30° on the dorsal/palmar plane of the distal third of the radius, and three transcortical smooth pins of 4,5 mm of diameter, inserted with a range of 15 a 30° on the dorsal/palmar plane of the proximal third of the third metacarpal bone, was reduced a fracture in the proximal portion of the third metacarpal bone. In addition, it compromised the fourth carpal bone and the carpometacarpal joint of the left forelimb of a thoroughbred weanling foal of five months old. The goal of the procedure, was to allow the allignment of the limb and stabilize the joint which has less movement in the carpus. The external fixation was maintained during two months, and then, it was determined the use of the specimen for breeding aims.

Imagen de apoyo de NEW TIMBRAL DIRECTIONS IN THE CONTEMPORARY CELLO REPERTOIRE: Analysis of works by Colombian composers from 2000 to 2015

Por: Sergio Andrés Castrillón Arcila | Fecha: 2019

This work analyses the repertoire for solo cello and cello with electronic media from 2000 to 2015 by Colombian composers, focusing on timbre as the main musical element explored. Nevertheless, a historical view on the European and non-European repertoire is included. This thesis consists of two parts. The first part includes chapters 1, 2, and 3. Chapter 1 classifies the cello playing techniques used in the most well-known pieces and studies the solo cello from the 17th century onwards, emphasising so-called extended playing techniques. Such classification serves as a tool for the further musical analyses in this work and as a foundation for the methodological framework in chapter 2, which discusses the notions of timbral modulation, timbral polyphony, and timbral re-signification. Chapter 3 discusses a new timbral development in the solo cello and cello with electronic media repertoire in the 20th and 21st century. This chapter surveys the crucial historical facts that generated a paradigm shift in the cello repertoire. This includes the emergence of different musical tendencies and the work of pioneer composers and performers. The second part of this study includes chapters 4 and 5, where the solo cello and cello with electronics repertoire from 2000 to 2015 by Colombian composers is analysed. The pieces involved emphasise a new timbral development within the repertoire. To summarise, this thesis emphasises how timbre was one of the elements that bifurcated the cello repertoire in the 20th and 21st century. Furthermore, this study describes how progressive composers and performers have deeply expanded playing techniques and the timbre of the instrument, and the exploration and combination of the medium with apparatus, artefacts, and new instruments into new ways of making music.

Imagen de apoyo de La vie comme parcours: les marionnettistes dans le métro parisien. Des groupes en mouvement dans des espaces de circulation

Por: Carlos Martín Carbonell Higuera | Fecha: 1998

L'expérience dans le métro est le résultat d'un parcours de vie volontairement assumé, où se mêlent les logiques de l'immigration et l'exclusion. L'étranger qui va pour rester, et surtout le sans papiers, arrive dans une situation où il est dépourvu d'éléments pour s'insérer dans le pays d'accueil. Sur le plan social, tous les liens qu'il avait constitués dans son pays de provenance sont absents, sauf les amis et les parents éventuels ou la solidarité d'origine qui peut être un appui dans un moment donné. Malgré tout, le processus pour arriver à se faire une place dans la société réceptrice est longue et n'est pas exempte d'inconvénients. La situation de départ pour l'étranger est, ainsi, une situation de «marginalité». Mais cette perception ne doit pas être prise dans le sens négative d'anomie. La volonté de l'individu qui arrive dans un pays étranger est de chercher des mécanismes ou des formules pour s'intégrer au milieu. «Qu'est-ce qu'il faut faire?» «Où est-ce qu'il faut aller?». Dans plusieurs cas, l'individu n'est pas tout seul, et il peut s'appuyer sur son réseau. Dans des communautés ethniques plus constituées, il trouvera un appui plus fermé. Mais pour ceux qui n'appartiennent pas à un tel groupe, la constitution d'une socialité s'effectue ailleurs, et la recherche de modes de survie est généralement réalisée en dehors des cercles sociaux traditionnels.

Imagen de apoyo de Prospective memory impairment in End Stage Renal Disease

Por: Maria Samira Gutiérrez De La Pava | Fecha: 2017

Existe una extensa investigación que analiza el efecto de la enfermedad renal en etapa terminal y el estado de las funciones cognitivas en general. No obstante, la evidencia sobre las deficiencias subyacentes en el ultimo estadio de falla renal sigue siendo poco estudiada en lo que respecta a la memoria prospectiva. Esta función es particularmente importante para un comportamiento competente en la vida diaria, así como para llevar a cabo futuras acciones previstas. Por lo tanto, parece pertinente examinar la posible disminución de la memoria prospectiva entre los pacientes con enfermedad renal y evaluar la función cognitiva inicial de estos individuos. Este estudio ofrece un primer enfoque al comparar el rendimiento entre pacientes con falla renal y controles sanos de la misma edad en pruebas cognitivas estandarizadas. Dichas pruebas incluyen el MMSE, el NART y las actividades diarias instrumentales (IADL). Este estudio evalúa el rendimiento de la memoria prospectiva utilizando el instrumento de la semana virtual. Los resultados muestran diferencias significativas para todas las pruebas cognitivas generales entre pacientes y controles, donde los controles sanos superaron a los participantes con falla renal en etapa terminal. El análisis reveló un peor rendimiento significativo de los pacientes con falla renal para tareas de memoria prospectiva independientemente de la regularidad de la tarea (regular-irregular) o el tipo de señal (evento-tiempo). Notablemente, los resultados sugieren la ocurrencia de deterioro prospectivo de la memoria entre la población clínica evaluada. Este estudio ayuda a generar conocimiento sobre los mecanismos cognitivos que se alteran a causa de ultimo estadio de la falla renal, particularmente la memoria prospectiva, lo que sugiere que este déficit podría tener implicaciones negativas en el programa de diálisis.

Imagen de apoyo de Creative learning in schools: Lessons from two initiatives developed in partnership between educational and cultural organisations

Por: Antonia Bonilla Mora | Fecha: 2018

Schools and cultural organisations have collaborated together to develop arts-based learning programmes in schools. At a first glance, this model seems beneficial as these initiatives increase students’ opportunities to access the arts and foster their creative expression, whilst pupils also acquire soft skills and strengthen their ability to work collaboratively. However, as one examines this matter closer, it becomes evident that certain aspects involved in the development of these partnerships are animated by motivations that transcend the ones circumscribed in widening students’ opportunities in creative learning. This dissertation is the result of an ethnographic study of a music and a dance initiative delivered in partnership between cultural organisations and schools across Greater London. Through constant comparison of the data, three themes surfaced as the principal categories animating arts-based learning in schools developed in partnership with cultural organisations: - Artistic partnerships maximise the creative potential and soft-skills acquisition of students. - Cultural organisations established an asymmetric relationship with their educative partners. - The motivations of cultural partnerships are dictated by priorities that transcend educational objectives. The analysis adopts Bourdieusian theory, mainly Bourdieu’s notion of cultural capital, to examine the way in which creative learning is introduced in schools. Furthermore, a Bernsteinian framework is employed to analyse the pedagogy that arts initiatives under the direction of artist-teachers enforce in the classroom. Moreover, the study contributes to arts learning and creative partnerships by providing recommendations that encourage participatory and collaborative practice in future endeavours.

Imagen de apoyo de The Ngo-Isation Dilemma: International Cooperation, Grassroots Relations And Government Action From An Accountability Perspective

Por: Lina Fernanda Buchely Ibarra | Fecha: 2012

This paper summarizes the results of a case study examining policy advocacy activities developed by the Fundación Esperanza (Hope Foundation) and the Plataforma Social HERMES (HERMES Social Platform) in support of Colombian Draft Law 070 of 2009 (creation of a National System for Migration and other regulations). It maps the actors and interests involved in efforts taking place between February and May 2010, to promote public policy in the field. The conclusion drawn from this research is that there are at least three ways of highlighting the relationships between civil society actors, government servants, grassroots and international cooperation agencies in the field of migration: instrumentalization (between NGOs and International Cooperation), complementarity and capture (between NGOs and local government) and impersonation (between NGOs and migrant population). The paper ends by presenting these three principal reflections within the framework of Migration NGOs’ accountability, an issue described as a challenge in the current law and development literature.
