Entrenador de sistemas secuenciales

[ES] En este trabajo se ha desarrollado una herramienta que contribuye al aprendizaje del alumnado de primer año del Grado de Ingeniería Informática de la Universitat Politècnica de València cursando la asignatura de “Fundamentos de computadores”. Se ha desarrollado una página web que permite acceder a ejercicios para resolver unas ecuaciones y un cronograma interactivo asociados a un circuito secuencial síncrono con biestables. Se ha optado por desarrollar una aplicación web para evitar problemas de compatibilidad y facilitar el acceso. Esto ha permitido incluir y manejar de forma más sencilla una gestión de usuarios y un registro de los ejercicios realizados por los alumnos. Esta memoria detalla las fases de análisis y especificación, diseño, implementación, la puesta en marcha y las pruebas que verifican el correcto funcionamiento de la herramienta, además de las tecnologías adoptadas.[EN] In this work, a tool has been developed that contributes to the learning of first-year students of the Computer Engineering Degree of the Universitat Politècnica de València, taking the subject of "Computer Fundamentals". A web page has been developed that allows access to exercises to solve equations and an interactive time diagram associated with a synchronous sequential circuit with flipflops. It has been chosen to develop a web application to avoid compatibility problems and facilitate access. This has made it possible to include and manage in a simpler way a user management and a record of the exercises carried out by the students. This report details the phases of analysis and specification, design, implementation, commissioning and tests that verify the correct operation of the tool, in addition to the technologies adopted.Buliman, O.

Traumatic lumbar Spondylolisthesis: Case Report

Only few cases of traumatic spondylolisthesis (from the cranial to lumbosacral joint) have been reported to date. Recovery of neurological function is dependent on the time of decompression and stabilization. We highlight the paramount importance that the time past between injury and surgical decompression have on neurological recovery and implant durability. Authors present the case of a 26 years old patient who suffered a motor crash 10 days ago before admission in our institution for cauda equina syndrome (L5 level). He also presented abdominal trauma with left kidney contusion, spleen contusion, thoracic contusion and left fibular fracture. X-ray and MRI examinations of the lumbosacral spine revealed grade 3 of spondylolistesis (60% anterior dislocation L5 - S1, intervertebral disc and posterior ligaments laceration, severe compression of the dural sac and dural laceration with CSF leakage through the posterior muscular mass). Surgery performed 14 days after the injury consisted in a posterior approach with L5 laminectomy, dural decompression and duroplasty with fascia lata, segmental reduction and stabilization with transpedicular screws, L5-S1 discectomy and anterior intervertebral grafting with two tricortical iliac crest grafts. Posterior lumbar interbody fusion was carried out using titanium screws (Solas system). Decompression, reduction with L5, S1 pedicular screw fixation, L5 – S1 disc excision and anterior intervertebral grafting with two tricortical iliac crest grafts is an appropriate surgical technique wich offer a good stabilization and fine functional recovering

Giant extracranial liposarcoma: Case report

Objective: Anaplastic liposarcoma of the head is an extremely rare entity. Seventy-seven cases of head and neck liposarcomas have been reported in the world literature since 1911. Radical surgery is the form of treatment advised.Clinical presentation: Authors report the case of a 62 years old female patient admitted in our institution for a giant extracranial tumor (122/88 mm), developed insidious over a period of 3 years and neglected. The patient agreed surgery only for the epicranial tumor. The lesion was completely removed. Postoperatory outcome was excellent concerning this tumor, although the histopathological result was not that great: high anaplastic liposarcoma.Conclusion: Liposarcoma of the scalp is rare. Diagnosis is made histologically. The histopathologic variant influences clinical behavior and prognosis. The treatment of choice is wide surgical excision.&nbsp
