Abstract: El tumor de Pindborg es una neoplasia benigna, rara, con carácter invasivo local y tendencia a la recidiva, que representa entre el 0,17 y el 1,8 % de todos los tumores odontogénicos, del cual tan solo se han publicado unos 200 casos, con una media de 4 casos nuevos por a o en el mundo. Se presentó el caso de un hombre de 39 a os de edad que acudió a la consulta de cirugía maxilofacial remitido de neurocirugía postraumatismo craneofacial, por presentar un aumento de volumen en el ángulo mandibular derecho. Se tuvo como objetivo publicar la existencia de esta infrecuente neoplasia por lo interesantes que resultan estos tumores por su evolución, dificultad en el diagnóstico, variantes de tratamiento y tendencia a la recidiva. Después de realizar exámenes de laboratorio, radiografías, tomografía axial computarizada y biopsia de fragmento óseo, se obtuvo extensión y diagnóstico de tumor de Pindborg en hemimandíbula derecha. Se realizó la técnica quirúrgica de hemimandibulectomía derecha y reconstrucción con injerto óseo de cresta ilíaca. La evolución del paciente fue satisfactoria. The Pindborg's tumor is a benign and uncommon neoplasm with a local invasive character and a trend to relapse accounting for the 0.17 and the 1.8 % of all odontogenic tumors with only 200 cases published in the literature and a mean of four cases per year at world scale. This is the case of a man aged 39 came our consultation of Maxillofacial Surgery referred from Neurosurgery Service after a craniofacial trauma and an increase of volume in right mandibular angle with the aim to publish the existence of this uncommon neoplasm due to the interesting of this type of tumor by its evolution, difficulty for diagnosis, variants of treatment and trend to relapse. After carry out laboratory examinations, X-rays, axial tomography computerize and biopsy of bone fragment, it was possible the extension and diagnosis of Pindbog's tumor in right hemi-mandible. The right hemimandibulectomy is performed as surgical technique and the reconstruction using bone graft of iliac crest. Evolution of patient is satisfactory.

Abstract: the tortilla is the most widely consumed food product in mexico and is produced through the traditional process of nixtamal. this method has two down-sides: the first is the amount of contaminated water that the process generates (nejayote); the second is the time loss generated by a batch-based production system. as a possible solution to this various methods have been developed that are based principally in extrusion. through heat extrusion the product is converted in a fluid pseudo-plastic due to the fact that the product is being cooked at the same time as it is being sheared and transported. this causes the viscosity of the cornmeal to be altered. in response to this problem, this investigation presents a system that transports and cooks cornmeal with specific quantities of water and calcium in order to obtain the nixtamal. the stages of transport contain a low shear screw that is connected to the rectangular oven by way of a geometric adapter. the rectangular oven was designed according to the rheological and thermal properties of the cornmeal. consequently, the geometry obtained suits the cooking process and offers a laminate flow in order to diminish the amount of shearing during the cooking process.

Abstract: La tortilla es el alimento más consumido en México y se produce a partir de masa obtenida por el proceso tradicional de nixtamalización. Este método tiene dos inconvenientes, el primero es la cantidad de agua contaminada que genera (nejayote), el segundo, son los tiempos perdidos, ya que la producción es por lotes. Como consecuencia, se han desarrollado métodos continuos que se basan principalmente en la extrusión. Mediante la extrusión con calor, el producto se convierte en un fluido pseudoplástico debido a que el cocimiento se realiza mientras éste se somete a cizallamiento en el transporte. Esto provoca que la viscosidad de la harina se altere. Debido a este inconveniente, en esta investigación, se presenta un sistema que transporta y cuece harina cruda de maíz con ciertas cantidades de agua y cal para obtener harina nixtamalizada. Las etapas de transporte y cocimiento se realizan por separado y en condiciones de bajo cizallamiento. La etapa de transporte cuenta con un tornillo de bajo cizallamiento, el que a su vez está acoplado al cocedor rectangular mediante un convertidor de geometría. El cocedor rectangular se dise ó de acuerdo a las propiedades térmicas y reológicas de la harina de maíz. Como resultado, la geometría obtenida favorece al cocimiento y ofrece un flujo laminar para disminuir el cizallamiento durante el cocimiento.
