Abstract: Introduction: Humans have gone through physical changes over the last 4 million years. The mouth, however, has not changed teeth quantity or quality. Eight incisors for fruits, vegetables and tubers; four little canines for little animals; eight premolars and twelve flat molars are used for crushing these foods, especially whole grains and legumes. The teeth crushing foods are the first step in the building of faecal matter. Foods are selected mostly according to cultural guidelines than to biological needs. The patterns of consumption are induced by the publicity of industrialized or processed foods. Material and Methods: This study design was observational, analytical, correlational, transversal and prospective. One thousand children (0 - 12 years old) were questioned in order to learn about the relationship between Weekly Eating Frequency (WEF) and Faecal Matter (FM) characteristics. The FM was classified as soft, normal or hard and the outcome was expressed as Dry Faecal Residue (DFR). The WEF and Weekly Bowel Movement Frequency (WBMF) were determined and tabulated according to times per week. Environmental factors, parents’ education level and children’s birth order were examined. Results: There was a strong association between DFR, WBMF and WEF. Environment and education level did not play a key role although birth order did matter. Conclusions: Fibre-free foods (dairies, meats, flours and sweeties or sodas) increased DFR. Foods containing fibre from vegetables decreased DFR, which in turn contributed to the WBMF. Lowest DFR was observed in children under Exclusive Breastfeeding (EB). Distant last-born children had higher DFR. Comments: Daily examples support these results and it is clear that children’s FM is built by their parents. We encourage parents to follow the “mouth nature” rather than the “advertisements nature”.
Associated or Concomitant Diseases Influence Significantly the Health-Sickness Concept in Celiacs  [PDF]

Abstract: It is well-known that feeling to be a healthy or sick person most probably results from the mind than from the body. We all know healthy people who feel sick and vice versa. We were interested in the health and sickness feeling of celiac people, their autorating of these feelings and its conditioning factors as well as their expectations. In this paper we present the results of an inquiry to evaluate these situations. We performed a descriptive, transversal and prospective study for 2 years to groups of celiacs and their families. They received a closed inquiry to be completed before the beginning of the talk. The inquiry included personal data and the co-existence of associated or concomitant (AoC) diseases. Most of the sample’s patients felt to be a healthy person (86.8%). Mothers see their children as healthy and the auto rated criteria is significantly better than the adult celiac person (“t”= -6.024 (p = 0.000)). AoC diseases influenced negatively in the feeling of being healthy and strongly decreased the autorating. Longer time passed on treatment reflects an increase feeling of health and of the autorating. In people with AoC diseases and who feel sick, the increased time of treatment did not show significant differences. People with “gluten sensitivity” felt sicker and auto rated themselves with a lower number than celiacs. Many pediatric gastroenterologists notice that the newly agreed definition of celiac disease, referring it as “autoimmune, chronic, incurable, and multisystemic”, results in a very negative character of the condition which might compromise the future labour of this people as well as their admittance to different health insurance systems.
Precariedad, movimientos de huelga y sindicalismo en Francia
Jon Bernat Zubiri Rey
Encrucijadas : Revista Crítica de Ciencias Sociales , 2011,
Abstract: Este artículo tratará de revisar las causas y la incidencia de la precariedad en las relaciones sociolaborales francesas, para entender las formas en que las nuevas composiciones del trabajo y sus expresiones en los movimientos de huelga pueden conducir, como causa y efecto principal, a una repolitización de los sectores precarizados, tratando de generar nuevas vías para una acción colectiva enraizada en la empresa y su territorio, y mejorando la centralidad en la orientación de los sindicatos y los movimientos sociales. Para esto apuntaremos algunos aspectos relevantes para diagnosticar las causas y la incidencia de la precariedad sociolaboral en Francia. Veremos el rol que estos sectores precarizados, empezando por los jóvenes, han tenido en los movimientos de huelga general acontecidos en los últimos a os para terminar, en la tercera parte, con una presentación de algunas huelgas locales en ámbitos laborales dónde el trabajo precario se ha normalizado en los últimos tiempos.
Convergencia oblicua: modelo estructural alternativo para la dorsal Neuquina (39os) - Neuquén Oblique convergence: alternative structural model for the Neuquén high (39o S), Neuquén
José Silvestro,Martín Zubiri
Revista de la Asociación Geológica Argentina , 2008,
Abstract: La dorsal neuquina es un lineamiento estructural de escala regional desarrollado a los 39oS, que se extiende por más de 270 km con orientación E-O, marcando el límite natural norte de la Patagonia. La actividad tectónica a lo largo de esta zona durante el Jurásico y Cretácico controló la sedimentación de la cuenca Neuquina desarrollando una serie de secuencias de crecimiento y discordancias asociadas. Por las características estructurales se reconoce un sector occidental con predominio de lineamientos orientados al NE relacionados a estructuras predominantemente compresivas y un sector oriental caracterizado por el predominio de lineamientos NO con desarrollo de estructuras transcurrentes. La orientación particular de este rasgo tectónico, aproximadamente perpendicular a los cinturones andinos, fue tradicionalmente explicado mediante dos modelos estructurales: transcurrencia e inversión tectónica. Basándose en nueva información de subsuelo y la disponibilidad de nuevos conceptos tectónicos, se plantea un esquema alternativo en donde se contempla el desarrollo de zonas dominadas por transcurrencia, estructuras relacionadas a inversión oblicua de hemigrábenes y el desarrollo de estructuras compresivas sin influencia de los rasgos extensionales previos. El arreglo en planta de las estructuras y su evolución en el tiempo puede ser originado por convergencia oblicua, bajo un campo de esfuerzos NO-SE, entre un bloque rígido ubicado al sureste (Cratón norpatagónico) actuando como contrafuerte con límite oeste paralelo a la traza del río Limay y límite norte paralelo al cauce del río Negro, que converge con una zona al noroeste factible de ser plegada representada por la cuenca Neuquina. Este esquema permite explicar la distribución y orientación de las zonas compresivas y transcurrentes y su evolución en el tiempo con desarrollo de estructuras cada vez más jóvenes hacia la parte externa del sistema. The regional scale structural lineament recognized as Neuquen high developed at 39o S latitude, is extended for more than 270 km in an E-W direction, defining the natural northern boundary of the Argentine Patagonia. The tectonic activity in this zone during Jurassic and Cretaceous times controlled the sedimentation of the basin, given place to a series of growth sequences and related unconformities. The structural features allows the recognition of a western sector where NE trending anticlines predominate related to high angle reverse basement faults and an eastern sector where the lineaments are NW trending and developed right-lateral wrench structures.

Revista Argentina de Radiología , 2010,
Abstract: Objetivo: Determinar las características de desempe o de la ecografía en el diagnóstico de las hernias de la región inguinocrural en pacientes con manifestaciones clínicas de pubalgia del deportista. Material y Métodos: Fueron realizadas ecografías de la región inguinocrural en forma bilateral a 400 pacientes consecutivos con pubalgia (800 regiones inguinocrurales exploradas; 379 pacientes de sexo masculino y 21 femenino; edad media: 28 a os, con un rango de 16 a 45 a os). Todos los pacientes eran deportistas -profesionales o amateurs-, provenientes íntegramente de un centro de medicina deportiva, derivados por un subespecialista en pubalgia. Los hallazgos ecográficos fueron comparados con los de la cirugía laparoscópica o con los resultados del examen físico y eventual seguimiento por consultorio externo. En consecuencia, se determinó la sensibilidad, especificidad y los valores predictivos positivo y negativo de la ecografía para el diagnóstico de hernias de la región inguinocrural en este grupo de pacientes. Resultados: Se detectaron hallazgos ecográficos que sugirieron la presencia de hernia en 128 regiones inguinocrurales (100 pacientes, 28 bilaterales). Al ser comparados con la cirugía y la clínica, la sensibilidad del método fue del 96,96% y la especificidad del 100%; los valores predictivos positivo y negativo, del 100% y 99,4%, respectivamente. Conclusión: La ecografía es un método de alta exactitud diagnóstica para la detección de hernias en pacientes con pubalgia del deportista que al examen físico no son evidentes o bien de naturaleza equívoca.

Soldadura de metales disimilares por láser de CO2
Garciandía, F.,Zubiri, F.,Etayo, J. L.,Cervantes, R.
Revista de Metalurgia , 1998,
Abstract: The work carried out in CETENASA (Laser department) in order to weld dissimilar metals is summarized. The involved metallic pair is M-35 and F-143, a high speed steel and a spring steel, respectively. Looking at the chemical composition of the involved alloys that will appear later, it can be easily understood the difficulty to obtain welded parts with structures metallurgicaly acceptable because of the high cracking degree that these materials show, specially M-35. The principles of a study which is being developed in the authors' laboratory and which shows some interesting CO2 laser possibilities are presented. En el presente documento se resumen los trabajos llevados a cabo en CETENASA (Dpto. Láser) para la obtención de puntos de soldadura entre metales disimilares. El par metálico estudiado es M-35 y F-143, correspondientes a un acero rápido y un acero para muelles, respectivamente. Debido a las composiciones químicas de las aleaciones implicadas se comprende la dificultad para obtener soldaduras con estructuras aceptables, desde el punto de vista metalúrgico, dado el alto grado de fisuración que presentan estos materiales, especialmente el M-35. El presente trabajo es un avance de los primeros resultados encontrados dentro de una investigación más amplia, en la que se demuestran las posibilidades que presenta la soldadura con láser de CO2.

On the Detection of Visual Features from Digital Curves Using a Metaheuristic Approach  [PDF]
Cecilia Di Ruberto
Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.331241
Abstract: In computational shape analysis a crucial step consists in extracting meaningful features from digital curves. Dominant points are those points with curvature extreme on the curve that can suitably describe the curve both for visual perception and for recognition. Many approaches have been developed for detecting dominant points. In this paper we present a novel method that combines the dominant point detection and the ant colony optimization search. The method is inspired by the ant colony search (ACS) suggested by Yin in [1] but it results in a much more efficient and effective approximation algorithm. The excellent results have been compared both to works using an optimal search approach and to works based on exact approximation strategy.
