Los generadores de calentamiento por induccion son puentes inversores con carga resonante, cuya mision es basicamente crear una corriente sinusoidal de gran amplitud sobre la "bobina de caldeo", que forma parte del tanque resonante. En el interior de esta bobina se introduce la pieza que se desea calentar. EI campo magnetico creado induce corrientes superficiales corrientes de Foucault sobre la pieza, que producen su calentamiento. Los tanques resonantes tambien llamados osciladores utilizados en la actualidad son el resonante serie y el resonante paralelo.

Aunque ya desde hace algun tiempo se vienen construyendo generadores de alta potencia basados en estos dos osciladores, el exito nunca ha. Tal y como se explica en la introduccion de esta memoria, los puentes inversores utilizados deben operar sobre una carga inductiva corriente retrasada para evitar el fenomeno de la recuperacion inversa de sus diodos y la consiguiente ruptura de los transistores.

De la restriccion topologica anterior se deduce que el generador paralelo debe conmutar a frecuencias inferiores a la resonancia, y el serie a frecuencias superiores. A esta restriccion topologica hay que unir otra que es exclusiva del calentamiento por induccion: La corriente por la bobina de caldeo debe ser sinusoidal.

De no ser asi, resultaria imposible disponer toda la potencia de calentamiento sobre la pieza en el espesor requerido por la aplicacion. La conjuncion de las dos restricciones anteriores obligan al inversor paralelo a funcionar a la frecuencia de resonancia del oscilador.

Esto imposibilita un control por variacion de frecuencia, regulandose la potencia desde la. Directory of Open Access Journals Sweden. Esta forma de presentarse las ulceraciones y la edad del paciente son frecuentes en pacientes VIH positivo Virus de la inmunodeficiencia humana, esto no pudo ser comprobado en el caso ya que el paciente dejo de asistir a consulta luego de recibido el tratamiento. We present a patient with multiple confluent ulcers in both the ventral and the dorsal tongue and lips, compatible with primary herpetic gingivostomatitis.

This way of presenting ulceration and patient age are common in HIV positive patients human immunodeficiency virus, this could not be found in the case because the patient stopped coming to see after the treatment. Acyclovir treatment was introduced mg tablets orally every 6 hours for 10 days. It is noteworthy that the treatments for herpes simplex virus with acyclovir are not approved by the Food and Drug Administration FDA but if accepted by the Center for Disease Control.

Two-phase characteristics of the feeding fluid of Cerro Prieto IV wells Mexico obtained by gas equilibrium; Caracteristicas bifasicas del fluido de alimentacion de pozos de Cerro Prieto IV Mexico , obtenidas por equilibrio gaseoso.

C Mexico. The gas composition of fluids produced by CP IV geothermal wells from the Cerro Prieto field was studied in order to identify different types of fluids entering the wells by estimating their temperature and excess steam. The results for the reservoir natural state indicated the presence of fluids with heterogeneous reservoir temperature between and degrees Celsius and excess steam values, which were found from negative boiled liquid that has lost steam when flowing to the well to one steam phase with zero liquid saturation.

Also, the results suggested that a steam phase could occur at CP IV which is added to the feeding fluid, depending on the operation conditions of the wells.

The origin of this steam could be the boiling of the deeper liquid due to a pressure drop. Se utilizo un metodo de equilibrio gaseoso basado en la reaccion de Fischer Tropsch y el equilibrio combinado pirita-pirrotita FT-HSH3. Los resultados obtenidos indican que en el estado inicial del yacimiento existen fluidos que muestran heterogeneidad en los valores de temperatura de yacimiento entre y grados Celsius , asi como en el exceso de vapor con valores desde negativos liquido que despues de ebullir ha perdido vapor en su trayecto hacia el pozo hasta uno vapor con cero saturacion de liquido.

El estudio individual de los pozos con fenomenos de ebullicion muestra que a traves del tiempo. Se obtuvieron secuencias sin contraste y postcontraste e. Ferro F, G. Mexico ; Melendez A, L. Recently the radiolabelled anti microbic peptides has intended as new radiopharmaceuticals for distinguish a bacterial infection of a sterile inflammatory process through a diagnostic image. The objective of this study was to develop a derived of the UBI radiolabelled with Tc m in high radiochemical purity and to evaluate the feasibility of using it in the specific detection of infectious focuses.

The molecular structures of the UBI as well as of other 2 cationic peptides used as control TatScr and TatScr , they were calculated and optimized in their more stable configuration by molecular mechanics procedures and quantum mechanics. The three radio complexes got ready experimentally and their stability in vitro saline solution is evaluated, human serum and cysteine solutions.

The experimental results correlated appropriately with the calculated data. The In vivo specificity was determined using Balb-C mice with induction in a paw of an infectious process and in another paw of a sterile inflammatory process.

During the last two decades the advances in imaging diagnostic of TMJ have greatly contributed to the assessment of the TMJ disorders.

The aim of this study was to investigate the potential usefulness of technetiumm labelled leukocytes scintigraphy in the diagnosis of TMJ inflammatory process applying a rabbit TMJ arthritis model. Arthritis was induced unilaterally with an intra-articular injection of ovalbumin in left ATM. On the contra-lateral side, the same dose of saline was injected.

After twelve days a computed tomography was realized. Scintigraphic images obtained five days after induction of TMJ inflammation showed the localization of inflammatory process. The results were expressed as cpm of activity found in left ATM and contra-lateral side. The authors reported 6 cases 3 males with ages between 17 and 63 years old, 4 with bone manifestations, one with repetitive urinary lithyasis and another with peptic ulcer and obesity, showing alternations in calcium metabolism and increased P T H.

THe scintigraphy showed preferential uptake of the tracer in the inferior right lobe 2 cases and in the inferior left lobe 4 cases of thyroid, with total location agreement in the surgery.

The histological study was parathyroid adenoma in all cases. These results emphasize the clinical necessity of a more initial diagnosis of primary hyperparathyroidism and it is possible to day that the metabolism of tetrofosmin is quite similar to sestamibi. Tetrofosmin can be used in parathyroid scintigraphy routinely. Design and characteristics of beta-excited X-ray sources; Caracteristiques des sources de rayons X excitees par des particules beta; Konstruktsiya i kharakteristiki beta-vozbuzhdennykh istochnikov rentgenovskikh luchej; Diseno y caracteristicas de las fuentes de rayos X excitadas por particulas beta.

En tenant compte du rayonnement de freinage, de l'ionisation de la couche K et de fluorescence provoquee par les rayons X, il est possible de degager une formule mathematique commode pour les spectres et les nombres de photons emis, en fonction de l'energie beta maximum, de l'epaisseur de la cible et de la configuration de la source.

En ce qui concerne les nombres de photons emis, les resultats de l'experience concordent parfaitement avec ceux des calculs theoriques, ce qui confirme la valeur de l'analyse. Il devient ainsi possible de mettre au point des sources de rayons X isotopiques repondant aux exigences des applications auxquelles elles sont destinees.

Enfin, les auteurs passent en revue les possibilites, avantages et limites des sources de rayons X isotopiques. Los autores han estudiado los rendimientos en rayos X y las distribuciones espectrales correspondientes a materiales de blanco que abarcan del cobre al uranio, para diversas geometrias fuente-blanco blancos de transmision, blancos de reflexion, blancos ''sandwich'' y mezclas intimas de la fuente y el blanco.

Para interpretar los resultados experimentales, los autores idearon un metodo de analisis de los procesos que intervienen en la produccion de rayos X por excitacion mediante particulas beta; dicho metodo. Scott, F. L'addition de plaques conductrices dans la region aval du miroir a pour effet d'attenuer la violence de l'instabilite en cannelures. Cette attenuation ne depend que de la resistance surfacique de ces plaques. Les auteurs ont etudie cet effet en mesurant le spectre de frequence des signaux en provenance de sondes a sintillateur enrobe placees au voisinage de l'enceinte a vide.

El plasma de 70 eV se inyecta mediante un cation en el espejo, con ayuda de un campo de gufa octopolar de tipo lineal. El campo especular se aplica durante un lapso igual al tiempo de transito del plasma. Se observan dos modos definidos de operacion, dependientes exclusivamente de las condiciones establecidas en el campo de gufa. Segun el primer modo, en el espejo el plasma no sufre estriado alguno, la mayor parte del mismo escapa en direccion axial, se observa una lenta, y anomala difusion radial y se emiten microondas en los ar-.

La emision de microondas no es compatible con la rama electronica de la inestabilidad de Harris. La estabilidad de este modo se atribuye a la union lineal por el plasma frio que sale por efusion de la zona del campo de gufa. Esta densidad disminuye al agregar al campo de gufa un cilindro de simetria axial.

El plasma resultante, atrapado en el espejo presenta inestabilidades en forma de estrias, perdidas radiales.
