Luxación acromio-clavicular posterior con fractura clavicular asociada

Se presenta un caso infrecuente de luxación acromio- clavicular posterior asociada a una fractura de tercio medio clavicular ipsilateral en un varón de 17 años. El diagnóstico se basa en la sospecha clínica y en las pruebas de imagen, siendo la TAC de particular utilidad. La reducción abierta y fijación coraco-clavicular con resección del extremo distal clavicular dio excelentes resultados. Se compara el tratamiento realizado con otros publicados, realizando una revisión de la literatura al respecto.An unusual case of combined posterior acromioclavicular joint dislocation and an ipsilateral fracture of the middle third of the clavicle in a 17-year-old male is presented. Diagnosis is based on clinical suspicion and imaging test, being CT scan particularly useful. Open reduction and coracoclavicular fixation with excision of the distal clavicle led to successful results. Treatment is compared with previous reports. A review of the literature is made

Kinetics and compositional dependence on the microwave power and DiH4/N flow ratio of silicon nitride deposited by electron cyclotron resonance plasmas

The archival version of this work was published in Journal of The Electrochemical Society. Hernández, M. J., Garrido, J., Martínez, J. and J. Piqueras. Kinetics and compositional dependence on the microwave power and DiH4/N flow ratio of silicon nitride deposited by electron cyclotron resonance plasmas. Journal of The Electrochemical Society 141.11 (1994): 3234-3237Silicon nitride layers have been deposited at a low temperature, 150ºC in an electron cyclotron plasma from nitrogen and silane as gas precursors. Deposition conditions have been varied in a wide range. Nitrogen flows from 25 to 400 sccm and silane flows from 2.5 to 35 sccm have been used in our experiments. The microwave power was varied from 100 to 1500 W. The result of the nitride growth kinetics show strong dependence on the silane to nitrogen flow ratio and on the microwave power. For large flow ratios and small powers the kinetics exhibits a nearly linear behavior whereas for low flow ratios and high powers a saturated regime was observed. Ellipsometry, infrared spectroscopy, and etch rate studies showed that the best material quality, 95% Si3N4, is obtained in the saturated regime for the lowest flow ratios and the highest powers used

Rapid thermal annealing behavior of amorphous SiC layers deposited by electron cyclotron resonance plasma

The archival version of this work was published in Journal of the electrochemical society 143.1 (1996): 271-277Hydrogenated amorphous silicon carbide, a‐SiC:H, has been deposited by electron cyclotron resonance plasmas. Operating in methane excess (Formula flow ratios between 2 and 4) and at high enough microwave powers, the deposited SiC films are close to stoichiometric. In these SiC layers, only small traces of the Formula and Formula stretching bands can be detected. Rapid thermal annealing leads to nearly complete dehydrogenation of the SiC layers deposited under these conditions as deduced from ellipsometric and infrared spectroscopy

Surface Electromyography of the Longissimus and Gluteus Medius Muscles in Greyhounds Walking and Trotting on Ground Flat, Up, and Downhill

In the field of canine rehabilitation, knowledge of muscle function in the therapeutic exercises prescribed is needed by physical therapists and veterinary surgeons. To gain insight into the function of longissimus dorsi (LD) and gluteus medius (GM) muscles in dogs, five Greyhounds performing leash walking and trotting on the ground flat, up (+7%), and downhill (−7%) were studied by surface electromyography, and the mean and maximum activity was compared. For the same incline, the surface electromyography (sEMG) of LD was higher (p < 0.05) at the trot than at the walk. In LD muscle, trotting uphill showed significantly higher maximum activity than any other exercise. A change of +7% incline or −7% decline affected (increased or decreased, respectively) the mean sEMG of the LD and GM muscles of dogs walking or trotting on the ground. When combined, the influence of gait and incline on electromyographic activity was analyzed, and walking at certain inclines showed no difference with trotting at certain inclines. Walking and trotting up and downhill added separate therapeutic value to flat motion. The results of the present study might contribute to a better understanding of the function of LD and GM muscles in dogs, this being especially useful for the field of canine rehabilitation

Adaptación de los métodos de enseñanza a los métodos de aprendizaje de los alumnos

El actual proceso de adaptación al Espacio Europeo de Educación Superior (EEES) que estamos viviendo en la Universidad, y que tiene como objetivo favorecer la convergencia europea en materia de educación universitaria, ha destacado algunos aspectos que pueden ser cambiados por parte de los docentes en aras de mejorar el proceso de enseñanza/ aprendizaje. En el presente artículo, presentamos unas directrices que pueden ayudar a los docentes a adaptar los métodos de enseñanza, para que se adecúen al máximo a las capacidades de aprendizaje de los alumnos que cursan sus asignaturas.Peer Reviewe

Hacia un programa de educación docente para la justicia social

Diseñar un modelo de Formación Docente para la Justicia Social implica generar espacios de aprendizaje colaborativos, críticos, reflexivos y políticamente comprometidos con la mejora de las oportunidades de vida de los estudiantes y la sociedad en su conjunto. Este enfoque sugiere una nueva manera de comprender la naturaleza de los procesos de enseñanza y aprendizaje a favor del desarrollo integral de todos y cada uno de los alumnos. En el presente artículo se abordarán contenidos y metodologías que conforman la esencia de un programa de formación de esta naturaleza, brindando nuevas claves y estrategias para repensar el desarrollo profesional de los docentes, de cara a constituirse en verdaderos agentes de cambio tanto dentro como fuera de las escuelas.A Teacher Education Program for Social Justice requires the design of collaborative and reflective learning experiences that foster political commitment towards the improvement of life opportunities for students and society as a whole.

Desarrollo del proyecto de reciclaje de equipos informáticos en el marco de Teruel Digital

En la presente ponencia se presentará la actuación de Reciclaje de Equipos Informáticos, que se realiza en la provincia de Teruel en el marco del proyecto Teruel Digital. En dicha actuación colaboran varios profesores del Departamento de Informática e Ingeniería de Sistemas y dos becarios, alumnos de la Escuela, y pretende recoger los equipos informáticos que ya no utilizan los organismos públicos, particulares y empresas, para ponerlos a disposición del resto de ciudadanos. Además se realiza asistencia técnica a las asociaciones que pueden solicitar equipos donados, así como potenciar el uso de software libre en toda la provincia.Este proyecto está financiado por el contrato OTRI 2006/0302

Molecular analysis of lungs from pigs immunized with a mutant transferrin binding protein B-based vaccine and challenged with Haemophilus parasuis

38 p.The molecular analysis of pigs vaccinated with a mutant transferrin-binding protein B (Y167A) from Haemophilus parasuis was compared with that performed for unvaccinated challenged (UNCH) and unvaccinated unchallenged (UNUN) pigs. Microarray analysis revealed that UNCH group showed the most distinct expression profile for immune response genes, mainly for those genes involved in inflammation or immune cell trafficking. This fact was confirmed by real-time PCR, in which the greatest level of differential expression from this group were CD14, CD163, IL-8 and IL-12. In Y167A group, overexpressed genes included MAP3K8, CD14, IL-12 and CD163. Proteomics revealed that collagen -1 and peroxiredoxins 2 and 6 were overexpressed in Y167A pigs. Our study reveals new data on genes and proteins involved in H. parasuis infection and several candidates of resistance to infection that are induced by Y167A vaccine. The expression of proinflammatory molecules from Y176A pigs is similar to their expression in UNUN pigsS
